Getting a heap dump on OOME from Tomcat-as-a-service on Windows?

[Laird Nelson]

I have Tomcat 6 running as a service on Windows 2003.

I go to the Tomcat service monitor, choose configure, choose the Java tab,
and add:

-XX:+HeapDumpOnOutOfMemoryError

...as one of the Java options.

When the OutOfMemoryError that I'm concerned about hits, I look around on
the disk to find an .hprof file.  I searched the entire computer; no such
file is found.

Any pointers?

Thanks,
Laird
