how to use Xalan with Weblogic as a web server

[Waldle Cai]

Hi all,
I've done a little program, which can translate XML to WML using Xalan API. But when tried to port the code to a servlet. It can't work. Weblogic gives me some runtime error. Looks like Weblogic can't work properly with Xalan XSLT.
The error message is as following:java.lang.NoSuchMethodError: org.w3c.dom.Node: method isSupported(Ljava/lang/Str
ing;Ljava/lang/String Z not found

Has anyone done similar program, which can work under Weblogic. Is there any setting I've missed out, ie classpath or system property..
Thanks and Regards

In fact "isSupported(String feature,String version)" is a method of the DOM interface "Node" only since the level 2 recommendation (http://www.w3.org/TR/2000/REC-DOM-Level-2-Core-20001113/java-binding.html). The classpath you are using with Weblogic probably contains a references to a DOM level 1 interface.

yup, you're right.after i changed the classpath so that Xalan jar files are before the Weblogicaux.jar. it works!!!
Thanks a lot
