Re: Java installation error

Please check the blackberry JDE from which u r developing & device OS.........Your blackberry JDE version should be lower than target OS of your device.

JAR file?

 

You should be pointing your browser at the JAD file, not the JAR file.

 

You deploy OTA by placing the JAD and the COD files on your server.

 

BTW, use this search:

 

"907 invalid jar descriptor missing required attribute"

 

and you will find many potential solutions.
