    Default java.lang.NoClassDefFoundError when i run my first project

    I use MAC OS v10.5.8 2.6 Processor: Intel Core 2 Duo 2.66 GHz and a Memory 4GB 1067 Mhz DDR3.

    I have the default java settings enabled:
    J2SE 5.0 32-bit
    Java SE 6 64-bit
    J2SE 5.0 64-bit

    I downloaded the default eclipse version for mac:
    Eclipse IDE for Java Developers

    I install and run it, then i create a sample application to test it works and it gives me this kind of error when i try to "Run" my project

    This is the error log:

    Hello trichask and welcome.

    It's not a question of people ignoring your post, but not everyone uses Eclipse and probably even less know the answer. Adding additional post to your thread is not going to get you the answer any faster.

    As a non-Eclipse user, the only thing I can suggest it that the application you are trying to run has not been compiled before attempting to run it.
    This is only a guess mind so might not be the answer you are looking for.

    I found the solution. Please check this post,

    To solve the issue:

    1. Decompress the file in the eclipse/plugins folder to any directory you like
    If you cannot find the exact version, just decompress the IBM ICU JAR that's shipped with your version of Eclipse
    2. In that directory, open the file com/ibm/icu/
    3. Replace = JDK

    with = ICU

    4. Recompress the file in the eclipse/plugins folder with the modified file

    Make sure Eclipse is started with a clean cache, and it should work. The easiest way of cleaning the Eclipse cache is to remove the .plugins folder of your workspace.

    A best way is to add this line in eclipse.ini file :
