Re: [Wrapper-user] Adding -Djava.system.class.loader=... parameter?

[Leif M. <le...@ta...>]

Lars,
Please add the following property to your configuration.  It will
cause the full generated command line to be logged.
wrapper.java.command.loglevel=INFO
This will let you see exactly how the Wrapper is launching the JVM.

If you wish, you can copy that command line into a batch script or sh
file.  Then, IMPORTANT, remove the wrapper.key property from the
command line.  This will let you run the JVM in a semi-standalone mode
which should let you test the JVM without the Wrapper binary in the
equation.   The java side of the Wrapper will still be there.  This
mode is not usually all that useful, but it can be helpful in removing
doubt about the Wrapper binary causing certain problems.

I may be able to help more if you post the resulting command line
along with your error.  Where are the classes referenced by your
custom class loader coming from?   Are you getting a
ClassNotFoundException on a Wrapper class, one of your application
classes, or a system class?

Cheers,
Leif
