Re: [Wrapper-user] How do you dump a process which runs as a service ( win2k )?

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

Robert,
    There are a number of ways to invoke a thread dump.
1) Using the WrapperActionServer class (see javadocs)  It lets you 
connect via telnet to
execute commands.   Drawback is that it requires a little bit of coding.

2) Use the WrapperManager.requestThreadDump().   Since you are using a JSP
container,  you can probably just create a little JSP page which 
contains the following:
<% org.tanukisoftware.wrapper.WrapperManager.requestThreadDump(); %>

3) Use JMX. There are even instructions for getting it working with 
JBoss.  This is
probably the easiest.

Cheers,
Leif
