Support

I have two slight issues:

1.  None of my output is hitting the console using:

            System.out.println(stringvalue);

2 I am trying to apply support for all screen resolutions but I cannot seem to launch the xlet in uWvga mode.  It works fine in Wvga and Svga modes.

I am also having problems adding the following lines to the .dalp file:

<display-mode size=”HVGA”/>

<display-mode size=”WVGA”/>

<display-mode size=”SVGA”/>

<display-mode size=”uWVGA”/>

Once they are added the build fails complaining about:

Buildfile: P:\TFC\Development\Java\workspace\ROIRicohXlet\build.xml

BUILD FAILED
P:\TFC\Development\Java\workspace\ROIRicohXlet\build.xml:23: The following error occurred while executing this line:
P:\TFC\Development\Java\workspace\ROIRicohXlet\ant\build\10-xlet-targets.xml:188: Failed to load P:\TFC\Development\Java\workspace\ROIRicohXlet\ROIRicohXlet.dalp

Build.xml line 23 = <import file="${common.dir}/10-xlet-targets.xml"/>

10-xlet-targets.xml =   <xmlproperty file="${xlet.dalp}" collapseAttributes="true"/>

Any light you can shed on this would be greatly appreciated.  If you need anything further from me please let me know.

Many thanks

Incident Question:
I am working on authentication and I thought I had everything working properly because it was working in the emulator as I was expecting.  When I installed it on the printer I get an exception of :

Question
Incident Question:

I am trying to implement a card reader and I am using the sample code from Ricoh Training Resources\Ver_R2_17\objects\SDKJ_AuthenticationPackage\usb 
I have it integrated into my code but when I try to start up the application UsbHostManager.getUsbServices(); dies because there is not javax.usb.properties file. I cannot find that anywhere in the example. If you could let me know what I am missing I would appreciate it.

I received a J522 error code. What is the issue?

Submitted by admin on

According to our documentation (sdkj_userguide_eRxxx.pdf, around page 16), a J522 error is an extended feature startup failed problem. In this case, most of the time, a problem is in the life cycle method initXlet().  Some things to keep in mind are the execution time of the life cycle methods.  If the application takes longer than specified by the specification to execute errors like J522 may occur.

I tried calling SysEventManager.getInstance().requestVisibleXlet(productId) to change to my xlet but I always get a GetOwnerShipResultException. What can I do?

Submitted by admin on

Seems like the UI is busy and the application will have to retry to make the switch.

I'm able to replicate in my lab with a quick switch to button and at times it may take up too 5 tries. Can you create the workaround to attempt a retry until successful or until a timeout occurs.

See code snippet below:

Incident Question:

Hi,

We have a report from Apple that the MFP is showing an error that has to do with too may windows open.  This is only happening with the Pharos solution at Apple.  This solution also has a Scan to e-mail application that Pharos authored special for Apple.  The Scan application is based off the sample provided on the RiDP site.

All MFPs at the site are experiencing this issue.  Here is a list.

Ricoh MP C4000 - Loses Trusted Cert Regularly - Java Version: 4.30.00 Firmware Version: 2.03

Ricoh MP C4000 - App Failure - Java Version: 4.30.00 Firmware Version: 2.03

Ricoh MP C4000 - App Failure - Java Version: 4.30.00 Firmware Version: 2.03

Ricoh MP C4501 - App Failure - Java Version: 7.23.00 Firmware Version: 3.07

Ricoh MP C4501 - App Failure - Java Version: 7.23.00 Firmware Version: 3.07  

Also RICOH Aficio MP C5502A

 

Because it's across all devices, we believe it is a bug in our code or at least we should be able to modify the code to better handle the windowing.  Here is an excerpt from the logs showing the error.

[stdout] unlockPanelOff key=com.pharos.ricoh.xlet.PharosXlet@26367726

[stderr]    at java.lang.Thread.run(Unknown Source)

I don't know what an SMC log is but I've attached RSH logs as an attachment.

Assuming the workflow is this:

  1. Pharos locks the panel with our authentication.
  2. User badges in
  3. Panel is unlocked
  4. User either prints or switches to scan.
  5. Logout
  6. Repeat with different users
  7. At some point the MFP shows the error message.

What would cause this error and what should we be doing to prevent it?  I suspect a resource leak or something like that and not properly ending either the Scan app or the Pull print app.

Thanks,

Nick.

I received a J301 error and JavaOutOfMemory Exception in the log? How can I solve this?

Submitted by admin on

The J301 Errors typically occur as part of the installation process. 

In sdkj_userguide_exxx.pdf error cause is defined as installation destination invalid and other errors.

The most common causes are:

1. The application was not signed properly.

2. There was a mismatch of the product id between the dalp file and the signature.
