Did you increase the heap size before starting anyway ?
Something like -Xmx1024M -Xms1024M
The default is 160K or something like that, which is not much ...

Subject: heap error
Do I have a memory leak here:
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
....
at
com.purdueefcu.statements.services.regmember.RegularMemberStatementServi
ce.bind(RegularMemberStatementService.java:67)
....
What isn't being garbage collected and leaking memory? Is the parsed
XML document being cached?
I'm selecting xml docs from the DB and binding them. I'm not doing
anything with the bound object...just testing the binding.
