Hi,

I have written some java program in which i am using some external jars. The code is running fine. I exported the jar as Runnable jar using the eclipse export option. I named the jar as abc.jar then i try to run it using "java -jar abc.jar". It started to execute but threw a exception java.lang.NoClassDefFoundError in between where i used the classes in the external jar, eventhough the refered jar files are there in classpath. Looks like classpath is getting reset to the current directory. I hope i am clear. Can anyone please help me resolve this issue.

Thanks in Advance

Hi Norm Radder,

I resolved the issue. Those external jars actually referring to some other jar. I think those jars where in the classpath thats why it was working when i run it from eclipse toolkit. But when i export my project as Runnable jar the manifest file will have an entry for classpath which points only to the current directory. So at run time my program wont find those additional jars. SO i also added those additional jars in my build path. That resolved the issue

Thanks,
Divith
