problem building Axis 1.2.1 from source

[Mike Woinoski]

I'm trying to rebuild axis.jar from the Axis 1.2.1 source. "ant compile" 
generates a number of errors like the following:

    C:\Home\Java\axis\src\org\apache\axis\SOAPPart.java:90:
    org.apache.axis.SOAPPart is not abstract and does not override abstract
    method renameNode(org.w3c.dom.Node,java.lang.String,java.lang.String) in
    org.w3c.dom.Document
    public class SOAPPart extends javax.xml.soap.SOAPPart implements Part
           ^
I've tried it with Java 5.0 and Java 1.4.2 (using Ant 1.6.2), resetting 
JAVA_HOME for the different compilers, but I get the same errors. Is the 
compiler using the wrong version of the Xerces libraries? Should I be using an 
older compiler (JDK 1.3?)

Thanks,
Mike
