Hi,

I tried to install the new version for eclipse 3.0.1.
Unfortunately is does not work.

-> double click on the jar-file eclipseUML_E301_freeEdition_2.0.0.beta..jar => nothing happens

-> java -jar eclipseUML_E301_freeEdition_2.0.0.beta..jar
a NullpointerException occurs:

I'm using java 1.5.0_01

Maybe you can help me.

Thanks.

First of all, you take a risque to use jdk 1.5 since we don't yet support it. Second, your jar may be corrupted. You need redownload again.
