Re: [Wrapper-user] JVM Restarts

Russell,
I tried to explain briefly in my previous mail, but most likely,
this is because your
reportServer class does not implement the WrapperListener interface.
The timeout is
happening because the WrapperManager class is never being loaded.
Please read the
integration section of the documentation. Especially concentrating on
Method 1. Most
likely, you will want to specify WrapperSimpleApp as your main class.
http://wrapper.tanukisoftware.org/doc/english/integrate.html
Until you have read the documentation, I don't really want to
rewrite everything that I
have already spent the time to painstakingly write in the
documentation. Believe it or
not, it will not be any easier to reread it here than it would be to
read it in the docs that
are already part of the distribution.
This is the most common request made by users, and I know that it is
simply a case
of user s not taking the time to read the docs... But if you have any
suggestions on what
I could have done to have made it easier for you to have gotten up and
running, I am
listening.
PS. Answering questions, takes real time out of my life. :-)
Please consider paying
for my time by supporting the project. Its cheap, you'll feel great
for helping out a
starving developer, and I promise I'll be in a better mood the next time
you post :-)

Cheers,
