A description 2 is a security element.
A description 3 is a resource element that contains a JSDK element (description 3A) designating a version of JSDK, a jar element (description 3B) designating a JAR file (execution file of an application) and its version, and a sub-jnlp element (description 3C) designating a SUB-JNLP file.
A description 4 is an update element that is for setting a method of performing an updating process. If auto is indicated, the updating process of an application is performed automatically, if manual is indicated, the updating process of the application is performed manually, and if mail is indicated and when an updating process of the application can be executed, an update notification is distributed to announce the fact.
A description 5 is an install element that sets a method of executing the installing process. If auto is indicated, the location of installation of the application is automatically selected. If manual is indicated, the location of installation is selected manually.
A description 6 indicates whether the type of application is “with GUI” or “without GUI”. As mentioned with respect to the update element, the installed JSDK application 147 is set as an object to be subjected to the update process.
A description will now be given an automatic update process that automatically updates the installed JSDK application 147.
If the update element indicates “auto” and there is present an application to be updated which is the same as the application for updating relating to the JNLP file (steps S102 and S103), the JSDK platform 148 compares the version of the application for updating with the application to be updated (step S104). If the version of the application for updating is newer than the application to be updated (step S105), the application to be updated is updated by the application for updating (step 106).
A description will now be given of a life cycle of the Xlet mentioned with reference to
The life cycle of the Xlet corresponds exactly to such as state transition of the Xlet. However, there may be many variations as to what state exists or how the state transits. This is the same also in the Xlet manager, the multi Xlet manager and other managers. The initialization state is a state immediately after generation of an Xlet instance. The transition to the initialization state is limited to once. The stop state is a state where service is stopped. The active state is a state where service is being provided. The transition between the stop state and the active state can be done any number of times. The end state is a state immediately after the Xlet instance is deleted. The transition to the end state is limited to once. As mentioned with reference to
It is a merit for managing the life cycle of the JSDK application 147 by the JSDK platform 148 that the memory capacity can be saved. Especially, in a multi-thread in which each of many JSDK applications 147 is performed as a thread, the above-mentioned merit provides a large existence value. It is a merit for setting the JSDK on 147 as the Xlet that the life cycle management of the JSDK application is easy.
1) Error Application
A description will be given of the error application 513 shown in
Here, an exception of Java (Registered Trademark) is handled as an error. Here, when an exception thrown by other JSDK applications is not caught, the error application 513 displays information indicating that the thrown exception is not caught. The exchange of exception here uses a thread group of Java (Registered Trademark). The thread group has a function that ThreadGroup.uncaughtException method is called by the Java (Registered Trademark) virtual machine if an exception thrown by another thread belonging to the thread group. The thread group further has a function to access information regarding other threads belonging to the thread group. There is a further function to set a relationship between parents and children (a tree structure) in the thread group. There is a further function to register a name of each thread group.
When producing each Xlet manager 531, the multi Xlet manager 532 gives a thread group to each Xlet manager 531 (S2). Each Xlet manager 531 produces a thread using the thread group concerned. Using this, the Xlet manager 531 manages information regarding a status of the Xlet and a life cycle of the user application 501. The Xlet manager 531 gives a thread group to the Xlet of the user application 501 when the Xlet of the user application 501 produces a sub-thread (step S3). The Xlet of the user application 501 produces a thread using the thread group concerned. Thus, a tree-structure of the thread groups is formed. The top-end of the tree-structure of the thread groups is managed by the JSDK manager 533.
2) Rule Application
A description will be given of the rule application 514 shown in
As the rule violation here, a rule violation of a service request made by the JSDK application to the API 551. As a specific example of the rule violation of the service request, there are a rule violation associated with a limit of a number of threads, a rule violation associated with a limit of a number of files opened, a rule violation associated with a printing process such as a color/monochrome setting, a print paper size or a number of print papers, and a rule violation associated with a scan process such as a color/monochrome setting, a paper size or a number of papers. Here, the rule application 514 displays information indicating the rule violation when the rule violation occurs in the service request made by other JSDK application to the API 551. The thread group of Java (registered Trademark) is used for monitoring the rule violation.
3) Image Forming Process
Although the RAW file is superior to the FFS file in respect of a high-speed reading and writing, the FFS file is superior to the RAW file in respect of providing files from the combination machine 101 to a PC or the like.
(Emulator)
Hereafter, the difference between the structure of
The panel manager emulator 744 is a class which emulates the panel manager 544 so as to convert an operation performed on the operation panel 202 into an operation on the keyboard 712 or the mouse 713. The emulator JSDK session 753 is a class which performs an establishing process of a communication path. The event emulator 754 is a class which emulates an operation of the combination machine 101. The JVM 755 is a Java (Registered Trademark) virtual machine for achieving the JSDK application 147 and the JSDK platform 148.
It should be noted that a starting procedure of the JSDK system in the PC 701 is the same as that shown in
4) Power Control
A description will now be given of a power control of the combination machine 101 of
Power supply mode of the combination machine 101 includes an “ON-mode”, which corresponds to a state where a power supply is turned on, and an “OFF-mode”, which corresponds to a state where a power supply is turned off. Although it is desirable to always set the combination machine 101 into the ON-mode so as to be in a standby state of an image forming process from a viewpoint of convenience, it is not preferable from a viewpoint of power saving to always set the combination machine 101 into the ON-mode so as to be in a standby state of an image forming process. Therefore, the ON-mode includes, in addition to the normal “standby mode”, which is under standby of an image forming process, various kinds of “power-saving mode” for saving power consumption during standby of an image forming process.
In the power-saving mode, a power source to component parts consuming a large power, such as an electric heater of the print part 122, a spindle motor of the HDD 233, a panel of the touch panel 311 or the like, during standby of an image forming process being set in a power-saving state, and, on the other hand, component parts consuming a small power, such as a power supply to the NIC 241 or the like are maintained to be in the standby state. Thus, the viewpoint of convenience and the viewpoint of energy-saving are compossible.
As examples of the power-saving mode, there are a “light-off mode”, a “preheating mode” and a “night mode”. In the light-off mode, a power supply to a heater is in a standby state, a power supply to a motor is in a standby state and a power supply to a panel is in a power-saving state. In the preheating mode, a power supply to a heater is in a preheating state, a power supply to a motor is in a power-saving state and a power supply to a panel is in a power-saving state. In the night-mode, a power supply to a heater is in a night state, a power supply to a motor is in a power-saving state and a power supply to a panel is in a power-saving state. In any mode, power consumption in the standby mode is smaller than power consumption in the power-saving mode.
When a fixed time (3 minutes, etc.,) passes in the standby mode or a fixed time zone (midnight, etc.) is reached, it shifts to power-saving mode. When an operation of the combination machine 101 is performed in the power-saving mode, it shifts to the standby mode. When a fixed time (3 minute, etc.,) passes in the power-saving mode or a fixed time zone (midnight, etc.) is reached, it shifts to the OFF-mode. When facsimile image data, scan data or print data is received, it shifts to the power-saving mode. When a power button is turned off, the power supply mode shifts from the ON-mode (the standby mode or the power-saving mode) to the OFF-mode. When a power button is turned on, the power supply mode shifts from the OFF-mode to the ON-mode.
Therefore, it is desirable to cause a platform to perform a power control.
The power manager 561 is a class which controls whether to permit or prohibit a shift to power-saving of component parts constituting the combination machine 101 in accordance with an executing condition of an image forming process or an executing condition of an application (JSDK application 147).
The machine state lock 562 is a class which controls whether to permit or prohibit a shift to power-saving of component parts constituting the combination machine 101 in accordance with a control request from an application (JSDK application 147) for an image forming process. As to a power control of the power manager 561, the application is involved passively.
Accordingly, it is no need to judge by the application itself as to which equipment is to be set in which power state. As to a power control of the machine state lock 562, the application is involved actively. This is used when the application performs a process taking a long time such as an image processing and when the application itself is required to prohibit a shift to a power-saving state.
It should be noted that although the machine state lock 562 controls a shift to power-saving of the component devices based on the control request with respect to the component devices of which control request is made by the application for an image forming process made a control request, a shift to power-saving is permitted as a default with respect to component devices of which control request is not made by the application for an image forming process. As to a power control of the machine state lock 562, the application is required to be involved actively when it is needed.
A description will now be given of the power control by the power manager 561. When starting scanning, the user application 501 sends a scan start request to the scan service 571 (step S301). In response to the request, the scan service 571 sends a notification of use of each component device used in the scan process to the power manager 561 (step S302). Upon receipt of an inquiry setting these component devices in a power-saving state from the SCS 169 through the system event manager 543 thereafter (step S303), the power manager 561 sends to the SCS 169 through the system event manager 543 a response to prohibit these component devices from being shifted to power-saving (S304).
When ending the scanning, the scan service 571 sends an open notification of each component device used for the scan process to the power manager 561 (step S311), and also sends a scan end notification to the user application 501 (step S312). Upon receipt of an inquiry setting these component devices in a power-saving state from the SCS 169 through the system event manager 543 thereafter (step S313), the power manager 561 sends to the SCS 169 through the system event manager 543 a response to permit a shift to power-saving of these component devices (step S314). Thus, the power manager 561 prohibits the component devices used for the scan process from being shifted to power-saving. There is no need for the user application 501 to be conscious of the above-mentioned process.
A description will now be given of the power control by the power manager 561. When starting printing, the user application 501 sends a print start request to the print service 572 (step S401). In response to the request, the print service 572 sends a notification of use of each component device used in the printing process to the power manager 561 (step S402). Upon receipt of an inquiry of setting these component devices in a power-saving state from the SCS 169 through the system event manager 543 thereafter (step S403), the power manager 561 sends to the SCS 169 through the system event manager 543 a response to prohibit these component devices from being shifted to power-saving (S404). Upon receipt of an inquiry of setting devices other than these component devices in a power-saving state from the SCS 169 through the system event manager 543 thereafter (step S405), a response to permit a shift to power saving is sent (step S406).
When ending the printing, the print service 572 sends a release notification of each component device used for the printing process to the power manager 561 (step S411), and also sends a print end notification to the user application 501 (step S412). Upon receipt of an inquiry of setting these component devices in a power-saving state from the SCS 169 through the system event manager 543 thereafter (step S413), the power manager 561 sends to the SCS 169 through the system event manager 543 a response to permit a shift to power-saving of these component devices (step S414). Thus, the power manager 561 prohibits the component devices used for the printing process from being shifted to power-saving. There is no need for the user application 501 to be conscious of the above-mentioned process.
A description will be given below of the power control by the power manager 561. Upon receipt of an inquiry to set the HDD 233 to a power-saving state from the SCS 169 (step S501), the power manager 561 checks whether or not the application open class can be stopped (step S502) and also checks whether or not the JSDK application 147 can be stopped (step S503). The results as to whether or not they cab be stopped are announced to the machine state lock 562. Accordingly, the power manager 561 confirms the machine state lock 562 as to whether or not the applications can be stopped.
If the application open class can be stopped (step S502), the power manager 561 sends to the SCS 169 a response to prohibit the HDD 233 from being shifted to power-saving (step S511). If there is the JSDK application 147, which cannot be stopped, in the JSDK applications 147 (step S503), the power manager 561 checks location of installation of the JSDK application 147 concerned. The location of installation of the JSDK application is managed by the install manager 545. Thus, the power manager 561 inquires the install manager 545 of the location of installation of the JSDK application 147. If the JSDK application, which is being executed or can be stopped, is installed in the HDD 233 (step S504), the power manager 561 sends a response to the SCS 169 a response to prohibit the HDD 233 from being shifted to power-saving (step S511). If there is no JSDK application 147, which is being executed and can be stopped, is installed in the HDD 233 (steps S504 and S505), the power manager 561 sends to the SCS 169 a response to prohibit the HDD 233 from being shifted to power-saving (step S511). Accordingly, the power manager 561 can prohibit the HDD 233 from being shifted to power-saving if the JSDK application 147 is installed in the HDD 233. There is no need for the JSDK application 147 to be conscious of the above-mentioned process.
A description will be given below of the power control by the power manager 561. When starting printing, the user application 501 sends a print start request to the print service 572 (step S601). In response to the request, the print service 572 sends a notification of use of each component device used in the printing process to the power manager 561 (step S602). Upon receipt of an inquiry of setting these component devices in a power-saving state from the SCS 169 through the system event manager 543 thereafter (step S403), the power manager 561 sends to the SCS 169 through the system event manager 543 a response to prohibit these component devices from being shifted to power-saving (S604). Upon receipt of an inquiry of setting devices other than these component devices in a power-saving state, a response to permit a shift to power-saving is sent. Therefore, when an inquiry to set the touch panel 311 in a power-saving state is received thereafter (step S605), a response to permit the shift to power-saving is sent (step S606). At this time, it is assumed that the combination machine 101 is in the power-saving mode and the touch panel 311 in the power-saving state. Additionally, it is assumed that the combination machine 101 is performing a printing process.
If an error occurs in the printing process, the print service 572 sends an error occurrence notification to the user application 501 (step S611) and also sends an error occurrence notification to the power manager 561 (step S612). In response to the error occurrence notification, the power manager 561 sends a request to change the shift to power saving of the touch panel 311 from permission to prohibition to the SCS 169 through the system event manager 543 (step S613). When the error in the printing process is cancelled, the print service 572 sends an error cancellation notification to the user application 501 (step S621) and also sends an error cancellation notification to the power manager 561 (step S622).
In response to the error cancellation notification, the power manager 561 sends a request to change the shift to power saving of the touch panel 311 from prohibition to permission to the SCS 169 through the system event manager 543 (step S623). When ending the printing, the print service 572 sends a release notification of each component device used for the printing process to the power manager 561 (step S631), and also sends a print end notification to the user application 501 (step S632). Upon receipt of an inquiry of setting these component devices in a power-saving state from the SCS 169 through the system event manager 543 thereafter (step S633), the power manager 561 sends to the SCS 169 through the system event manager 543 a response to permit a shift to power-saving of these component devices (step S634).
Thus, the power manager 561 changes the status of the shift to power-saving of the touch panel 311 from permission to prohibition if an error occurs in the printing process when the combination machine 101 is in the power-saving mode, and, on the other hand, returns the status of the shift to power-saving of the touch panel 311 from prohibition to permission if an error occurring in the printing process is cancelled when the combination machine 101 is in the power-saving mode. There is no need for the JSDK application 147 to be conscious of the above-mentioned process. The JSDK application can perform the display of error occurrence without being conscious of the above-mentioned process.
