Hi, APOLOGIES Apologies if this appears in MIME (I hope not), I am using the web version of MS Outlook, have no access to the full client, and thus have no control over the options. SUMMARY I've got a bit of a problem with Jakarta Tomcat 3.2.1/3.3.1 I am running a small XML application that takes the getDocumentElement() of a document class and appends it onto another class. To do this, I use the importNode() function. When I test it on my home server, which is a modified version of the JSDK2.1 server (modified in the sense that I have randomly added .jar files as needed), the application works. When I test it on Tomcat 3.2.1/3.3.1, it doesn't. DETAIL The code in question is as follows: Document temp=null; if (result==null) temp=builder.parse(new InputSource(new StringReader("<result>No records</result>"))); else temp=builder.parse(new InputSource(new StringReader(result))); Node temp3=temp.getDocumentElement(); Node temp4=temp2.importNode(temp3,true); root2.appendChild(temp4); return temp2; The code is sloppy, because I've been trying to debug it, so I tried various permutations of the same code. This was the last state of the code. The code bombs on "Node temp4=temp2.importNode(temp3,true);" it reports the error message: java.lang.NoSuchMethodError at sf_maincontrol.setupXMLSearchEngine(sf_maincontrol.java:109) at sf_maincontrol.run(sf_maincontrol.java:57) at sf.searchme(sf.java:68) at sf.doPost(sf.java:16) ... This is odd, because as can be seen on the earlier lines, it is running various other methods of the document class just fine. Originally, I thought it was because I was using an old version of Tomcat (3.2.1), so I switched to Tomcat 4.0. Tomcat 4.0 was so completely different (and I couldn't get it to install), so I switched to 3.3.1, which worked. All of my own special jars are in the web-inf/lib directory, etc. etc. I just can't understand why it isn't running importNode, but is running all the other methods of the Document class. Thank you Cecil Chua
