> I am using Struts 2.0.6, Tiles 2.0 and Tomcat 5.5.27. The application runs
> fine in the past, but recently we did some load testing and get the following
> exception intermittently during load test:

> exception

> Both exceptions are from DigesterDefinitionsReader.java and root cause for
> the second one is "org.xml.sax.SAXException: FWK005 parse may not be called
> while parsing.".
> I am wondering if tiles is thread safe in reading xml definitions. What I
> understand is it is using Xerces parser to parse tiles.xml, but Xerces parser
> is not thread safe [http://xerces.apache.org/xerces2-j/faq-dom.html], so
> there should be some synchronization.
