[jdom-interest] java.lang.NoSuchMethodError when using tomcat

[Otavio Rezende da Silva]

Philip,

I've also experienced this problem. This happens beacause Tomcat's got an 
embeded XML parser. I guess it's located in a directory called lib, in a 
file called XML.jar.
This parser is based on the release 1 of DOM, and JDOM needs to be used with 
the 2nd release. To correct this problem You will have to replace the 
org.w3c.dom files of this package by the 2nd release ones. You can do that 
opening the jar file using a zip tool (WinZip for example) and adding the 
DOM rel 2 files. As you said the application is running well outside the 
webserver, you must have the files somewhere in your classpath.

Cheers,

Otavio Silva
