[Wrapper-user] Re: [Wrapper-cvs] JVM Restarts

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

Russell,
    You made a common mistake.  The mainclass is the class that is loaded
when java is first loaded.  This will be your class if and only if you have
manually implemented the WrapperListener interface, which you have not.
I tried to warn about this in the default wrapper.conf file that comes with
version 3.0.5.
    Please go back and read the integration documentation.   You will most
likely want to use Method #1 and set the mainclass to be WrapperSimpleApp

http://wrapper.tanukisoftware.org/doc/english/integrate.html

    Post back if you still have problems.

    By the way, I replied to the wrapper-user list as that is where this 
post
should have gone.  The wrapper-cvs list is only monitored by people who
want to keep track of changes to the wrapper source, or who have
comments on the changes.

    Cheers,
    Leif
