The problem is caused by introducing (redundant) apache xml processing
libraries in the classpath while running application under java 5. The
problem is not limited to hackydev web application. It will appear so
long as all of the following conditions are met:
- your code uses classes in javax.xml.transform to do XSLT transformation
- you are using java 5
- you have apache xml libraries in your classpath
For example, one of my cruisecontrol custom extensions has the same
problem while running java 5, since cruisecontrol put apache xml
libraries in its lib directory.
There _might_ be other xml incopatibility issues, but I have _not_
experienced them so far.
As far as hackystat is concerned, there is no code doing xslt
transformation. So far, it seems it's ok even if there is apache xml
libraries are in the classpath.

Hackydev.
I think this is a CruiseControl related problem associated with
transforming the xml reports. I had this problem too and I think
Cedric's solution is correct.
thanks, aaron

I guess I don't quite understand the nature of the problem yet.
Thanks!

In an attempt to standardarized HackyDev machine on java 5 and
tomcat 5,
there is following error if you try to access build report currently:
javax.xml.transform.TransformerFactoryConfigurationError: Provider
org.apache.xalan.processor.TransformerFactoryImpl not found
Basically, tomcat 5 suplies 2 redundent files "xercesImpl.jar and
xml-apis.jar" (might not be redundent if you are using java 1.4), and
overrides the default system wide property
"javax.xml.transform.TransformerFactory"
with
"org.apache.xalan.processor.TransformerFactoryImpl".
But java 1.5 uses sun implementation of TransformerFactory.
The problem can be solved by deleting the 2 redundant xml related jar
files in "tomcat\common\endorsed" directory. I'll do it tomorrow when I
have physical access to HackyDevmachine.

Cedric
