Hi all,
I've been using jxpath v1.1 to implement a central store of system
configuration backed
by an XML document. I read the XML document into a DOM tree and then execute a series
of jxpath
getValue() calls on the DOM to get configuration values. That all works great except
under heavy
load, say 100 threads looking for config values. Every so often I get the following
exception.
Do all calls to getValue() need to be synchronized? That would be unfortunate. Is
there any
alternative? Is this a bug that's fixable in the jxpath source?
Thanks. Love jxpath by the way.
