[jdom-interest] JRun and JDom

Hi Tako, 

Yes, those two librairies are useful!! :-)) 
They are part of the Java extension packages that are provided with JRun. 
And JRun is using them to parse the web.xml files : launch your JRun
administration console, you will probably have some trouble with the
left-hand side tree.

So, you have two solutions. 
1. You want to use Xerces as your main parser. 
This is what I do, but this is not the solution I would recommand (I do this
because I need Xerces to use Apache SOAP). 
Just put your xerces.jar file at the beginning of your classpath in your
JRun global.properties file. 
Mine looks like that : 

2. You want to stay with the standard Java extension, and in that case use
JAXP. I do this for my production servers. 
JAXP is provided by sun (java.sun.com). 
Download JAXP 1.1 : you will get 3 files -> crimson.jar, jaxp.jar, xalan.jar

Just put them in your JRun lib directory - yes, replace your old jaxp.jar by
this one. 
And voilà, it should work.
