Re: [Wrapper-user] WrapperJarApp: Encountered an error running main..

Koen,
Can you try the following:
wrapper.java.classpath.1=../lib/wrapper.jar
wrapper.java.classpath.2=../lib/Csv2Db.jar
wrapper.java.classpath.3=../lib/lib/*.jar
Adding your jar to the class path should already fix your problem.
(I use a wildcard for the other jars just to make it a little bit more
easy to handle the classpath)
The Classloader handling in your application is slightly different
when running with the WrapperJarApp.
You might need to get a little bit changed to actually use:
<Your Class>.class.getClassLoader().
instead of the static way with ClassLoader...
Changing the handling to that way, you wouldn't need to define
Csv2Db.jar in the classpath...
Please let me know if you have any further questions.
Best Regards,
Christian
