Subject Re: Getting a bunch of java.lang.Exception: Could not load *.class errors.
Date Thu, 08 Oct 2009 17:10:14 GMT
With netbeans it's not an easy task.

It comes from the server you selected. The best option is to select a
Geronimo server, though the Geronimo plugin for netbeans is only
available in 6.8, and only supports an older version of geronimo 2.0
or something - it technically supports them all, but doesn't recognize
newer installations as it looks for the geronimo-kernel jar with a
specific version. I got around this by modifying it's source and
changing the file it looks for to the one in my geronimo installation
and all it's features worked from here. Though it's very limited and
can only deploy WAR archives, it does help with the classpath
problems.

The best practice option for this is to define the property in your
project's run options. When you go into the project's properties and
to the Run page where you select the server, you'll see a text field
at the bottom that allows you to enter options. Define the property
there, something like: -Dj2ee.platform.SOMETHING.classpath=

An alternative is to select a null server (open your project's
configuration files and remove/empty the server selection).

And another alternative (which I don't recommend you do unless you
don't need the other servers ever again) is to edit netbeans' internal
representation of the glassfish servers and modify their classpaths.

Try the first option first, if it doesn't work reply to this e-mail. I
was successful in using that technique, so if it doesn't work for you
we only missed something.
