[jira] Created: (TILES-505) DefinitionsFactoryException: XML error
reading definitions under large load
DefinitionsFactoryException: XML error reading definitions under large load
---------------------------------------------------------------------------
Key: TILES-505
URL: https://issues.apache.org/jira/browse/TILES-505
Project: Tiles
Issue Type: Bug
Components: tiles-core
Affects Versions: 2.0.0
Environment: Tomcat 5.5.27, Struts 2.0.6.
Reporter: Boxiong Ding
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:
2010-04-08 05:51:09,970 ERROR [http-443-Processor22] ? - End event threw 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.

------------------------------------
Are you sure the problem was fixed in 2.0.7? I don't see much difference in the source code. I will give a try any way.

What do you mean with "won't even start?" Please post any log you have.
Just a note: the 2.0.x branch is not maintained anymore. You are encouraged to upgrade to the Tiles 2.1.x branch for a stable version.
However I doubt that Struts 2.0.x is compatible with Tiles 2.1.x

> 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.
