2 options will help Xerces consume less memory
1)turn OFF validation for any Documents created from the
DocumentBuilderFactory e.g.
factory.setValidating(false);

2)turn OFF namespace awareness for any Documents created from the
DocumentBuilderFactory e.g.
factory.setNamespaceAware(false);

Subject: java.lang.OutOfMemoryError: PermGen space


> I'm having some problems figuring out what webapp is causing this problem.
I figure the cause of this is the fact that garbage collector does not clean
up and memory allocated for java object generation is used . Right now i
have a hunch on one of the webapps:
> I have an application which connects every 5 minutes to an url, opens a
stream and reads some data(about 20 lines from an xml file) appends that
text to a local file, draws a chart based on that data and creates some html
files. The xml files where the text is appended can get to a max of 30 kb at
the end of the day. That's not that much. But still, could something like
this cause the PermGen space error? 10x
