Hi! I've developed an application in J2ME for Motorola's i88s device which has GPS. I use Sun's J2ME Wirelesss Toolkit. I want to include GPS' external class libraries in my application. These GPS class files are packaged in a ZIP file. I put this ZIP file in 'lib' directory under application's directory. ( Name of my application is : 'GuiTests' and my Wireless Toolkit Installation dir is 'C:\WTK104'. So this ZIP file is in 'C:\WTK104\apps\GuiTests\lib\'). When I put this ZIP file in the above said folder, the application gets compiled but verifier gives an error saying, "Class loading error: Wrong name com.sun.kvem.ktools.ExecutionException: Preverifier returned 1 Build failed" I also tried to put this ZIP file in 'C:\WTK104\apps\lib\' directory as a common external library for all the projects, but it gives the same error. Any suggestions are highly appreciated. ~Vaibhav.
