You see parser errors such as: 

java.lang.NoSuchMethodError at 
org.apache.xpath.DOM2Helper.
getNamespaceOfNode 
(DOM2Helper.java:348) at
 org.apache.xml.utils.
TreeWalker.startNode
 (TreeWalker.java:281) at
 org.apache.xml.utils.
TreeWalker.traverse 
(TreeWalker.java:119) at 
org.apache.xalan.transformer.
TransformerIdentityImpl.
transform 
(TransformerIdentityImpl.

Check that you have followed the instructions to copy the XML parser-related JAR files to the servlet container's lib/ directory, and that you have removed any default parser.jar files.
Running iPlanet, you see the following in your browser: 

GX Error (GX2GX) socket
 result code missing!!!
There is a mismatch between the web.xml and ias-web.xml files. All servlets mentioned in web.xml must have a corresponding entry in the ias-web.xml file. Use the kguidgen utility to generate a GUID for the servlet.
