There is an extra API for J2ME to support bt ( JSR82 )
http://www.jcp.org/en/jsr/detail?id=82
I have downloaded an application which uses bluetooth and J2ME.
The name of the application is BlueChat and the website where this application is available for download is http://www.benhui.net
My problems regards to this application are as follows:
1. I want this application to get compiled in SUN WTK 2.0. The web site gives instructions for running this application on SUN WTK 2.1 in windows platform but does not give any help on Linux platform
2. The website which hosts this application gives 2 jar files one for MIDP 1.0 and the other one for MIDP 2.0 the website says that to download anyone of the jar files and then to paste it in the WTK21/lib/directory which will overwrite the old midp jar file which comes with SUN WTK by default.
Since i am using Linux for development i downloaded WTK 2.0 Linux version .
i couldnt find a default midp.jar file so i did not know where to paste the new jar file which comes with this bluetooth application.
This process is done to compile this application using SUN WTK which has no bluetooth support and then to run this application using Nokia Series 60 MIDP SDK 0.3 beta.
3.In windows i followed the instructions given in the website and the application got compiled but the emulator did not startup due to some problems with the emulator but i did not have any problems with compilation .
4. In Linux i am facing problems in compiling the application.
I placed the jar file that comes with the application in the application's LIB directory when i did this i get one error .
The error is
"Error Preverifying class com.sun.ksecurity.MD5" "Error:native methods should not appear" Build Failed
This is what i get so i am unable to compile the application. So kindly help
Thanks
