Hi, i've installed personal jvm on my pocket PC, I wrote a simple java program and downloaded the class file to the pocket pc, now when i click the class file the jvm shows an error "cannot find clas ..".
I tried to set the classpath using a registry editor ie
"\Program Files\Java\bin\pjava.exe" -classpath "\myclass" -file "%1".
even then it is not finding the class. I placed my class file in one of the directories containing a example supplied along with the pjava installation since the example is running fine.still, i get the same error. ANy idea how to solve this??

Thanx..
