Re: Barracuda and Jivan

Hi Jancsi,

I am still looking into that problem. However, I know that the org.w3c.dom.ls package has 
changed recently. Yes, the W3C has changed the the interface classes within this package. 
  Xerces 2.4.0 used the old interfaces, where Xerces 2.5.0+ uses the never ones. Jivan is 
based on the older interfaces. Well if I change Jivan to use the never interface, Jivan 
applications will break when they are deployed on older system.

On Tomcat the problem is that the Xerces parser from the CATALINA_HOME/common/endorsed 
even if the classes are provided by the jivan.jar. So I need to change Jivan so it can 
work with 2 different sets of interfaces. Other application server have similar 
'endorsed' techniques, causing the same problem.

Tomcat 5 uses Xerces 2.5.0, but Tomcat 4 uses versions pre Xerces 2.5.0. I will work on a 
fix to be released as soon as possible. But that will be after Xmas, sorry. If you are 
really working over Xmas, you could try to downgrade your version of Xerces to 2.4.0.
