hi!

i am working on a projekt and would like to use the treetag from http://www.jenkov.dk.
put it doesn't work in my environment. i'm desperate...

please can anyone help me who used/knows this tag?
i get always an 'HTTP Status 500'
-> org.apache.jasper.JasperException
root cause: java.lang.NullPointerException
com.jenkov.prizetags.tree.impl.TreeTag.expandCollapseNode(TreeTag.java:107)
com.jenkov.prizetags.tree.impl.TreeTag.doStartTag(TreeTag.java: 134)
...

i have installed the treetag like described it in the userGuide-file.
i put the jenkov-prizetags-bin-v.2.1.5 in my WEB-INF/lib directory and the treetag.tld in my WEB-INF directory. to declare the use of the tree tag i put the following declaration at the top of my jsp page:

<%@ taglib uri="/WEB-INF/treetag.tld" prefix="tree" %>

(i use jsp 1.2 and jdk 1.4 and tomcat 5.5.4)

and it doesn't work. i'm helpless...
i need your answer very badly, please!

thanks in advance, lana
