    Re: problem in installing jar file?

    Several problems could cause this.

    Work through this list of common installation problems. If you don't find the solution, remember to tell us:

    1. what device you're installing on
    2. if you are installing a JAD and JAR, or just JAR
    3. the contents of JAD, and/or the JAR's MANIFEST file

    Invalid Installer Problem in mobile

    Hi,

    I just completed developing a j2me application (CLDC 1.1, MIDP2.0) and it worked fine with the emulator (Sun Java Wireless Toolkit) while testing. But when I tested the jar file in the mobile (Nokia 7210 MIDP2.1 compatible) it showed invalid application.

    I also tried running the jar file directly form the SunJava Emulator seperately but it showed manifest file corrupted.

    I would be pleased, if anyone could help me with this problem.

    Thanking you in advance.

    Re: problem in installing jar file?

    Which device are u using? The CLDC and MIDP configuration must be in according to ur phone.

    If they're the same, then CleanAndBuild ur application and use the new jar&jad files created.
