Hi,
Being a j2me developer, I came across the task of installing a signed midlet in a Tytn (using Intent vm). I have 2 valid certificates (verisign and thawte) and the midlet fails to install with invalid permissions for both of them.
My question is: does the WM (or jvm for that matter) support installation of signed midlets? Is this WM dependent or JVM dependent? Does anyone came across this problem?
Thanks in advance for any help!

I have a Qtek S200 with:
Microsoft Windows Mobile 5.0 OS 5.1.195 (Build 14928.2.2.0).
and
intent Java MIDlet Manager Runtime MIDP 2.0: v10.1.7.545 (Build 20051117)
I want to develop a MIDlet which needs file access and/or camera access. I know that device needs the optional packages (JSR-75 PDA-API and JSR-135 Mobile Media API) to accomplish that. And it seems that these optional packages are not supported by the MIDlet Manager.
I have tested this MIDlet already on a smartphone (Nokia N73). The Java Micro Edition of this Phone supports several Optional Packages. It can not be possible that a PDA provides less functionalities than a Smartphone.
1. Is it possible to upgrate the JVM (MIDlet Manager) on the device? So that I can use these optional packages.
2. Does anybody know which MIDlet Manager supports these functionalities?
I have found a newer version of the intent Java MIDlet Manager
Runtime JTWI 1.0: v11.1.7.1023 (Build 20060907)
This version provides the optional package JSR-75 which is needed for file access.
I found a download here: http://wronek.wikidot.com/java-wm
But this version does not provide the Multi Media API JSR-135 which is needed to use the devices build in camera.
So if anyone knows an other MIDlet Manager please reply.
I've found an other MIDlet Environment which supports file access (JSR-75).
It is the IBM J9. The installation of this Environment is a bit tricky but the GUI of this MIDlet Environment is more beautiful than that of the intent Java midlet manager.
Here you can find a good installation discription:

Hello, I've not found anywhere answer to my question so I ask here. Don't you know any 100% working Java Virtual Machine to set on Windows Mobile 6 Emulator (and the best on free commercial license)?
Soft (emulator) I use is from:
http://www.microsoft.com/DOWNLOADS/details.aspx?FamilyID=38c46aa8-1dd7-426f-a913-4f370a65a582&displaylang=en
Another interesting thing is that I downloaded and launched WM 5 Emulator and without any problem installed JBed platform. Unfortunatelly WM 6 doesn't allow me to launch any midlet (using JBed). It throws:
Code:
The file 'jbed' cannot be opened. Either it is not signed with a trusted certificate, or one of its components cannot be found. If the problem persists, try reinstalling or restoring this file.
Myisafu brakes installation process and couldn't reach to the end.
Many similar topics are to found on the internet, but none of them touches emulator problem. All of them are with reference to real devices.
Regards.
Hello;
I am developing a java based application to work on mobile phones. HTC p4350 is one of the phones we want the app to work on.
Our application runs on various other phone models, but when i want to install the midlet on intent midlet manager, it raises error : midlet install unsuccessful. Another midlet manager (IBM J9) is installed on HTC P4350 and the application works fine.
Our application generates problems only on HTC P4350 and intent midlet manager. And the error message gives us no clues.
Does anybody have any idea about why this problem occurs and how this problem can be solved?
I am using an HTC Ozone from verizon.
It's winmo 6.1.
I installed JavaFX 1.2 and then the java programs are installed ok,
but when I run them I get the message:
Exception: Application not authorized to access the restricted API...
From digging around I find out that the application might be blocked because of unsigned signature.
What should I do to fix this ?
Thanks
I can't remember what the Java program is called which allows you to run java apps.
But it comes with the wm6.5 rom which 3VOLUTION made.
for those who might encounter the same problem, I found the java bible here http://forum.xda-developers.com/showthread.php?t=339579
and downloaded Esmertec Jbed
and now all java runs fine.
Cheers!
