SV: SV: [jdom-interest] Error in build : trinity

[Michael_Harley at bankofscotland.co.uk]

hello Per,

We have a class XMLParser, which contains the class variable;

Document doc;

When you mention concurrency are you considering the getRootElement()
method be 'synchronised'?

I have checked the dtd file used by the XML and the word 'trinity' does not
appear there either.

Thanks

Mike H

Hi,

The doc variable seems to be a field, not a method local variable.
If this method is declared in the servlet, I would expect very
strange behaviour if you have two concurrent requests, each acting
on the same Document instance.
