ClassCastException after upgrading to axis1.4

axis1.4 (java)
weblogic 8.1

I've recently upgraded from axis1.2 to axis1.4. Everything compiled and

built fine, however, on the first soap request I get a class castexception . Here's a few lines from the stacktrace:


Caused by: java.lang.ClassCastException: java.lang.String
   at
org.apache.axis.message.MessageElement.addTextNode(MessageElement.java:1389)
   at org.apache.axis.message.SOAPHandler.addTextNode(SOAPHandler.java:148)

My first thought was that there was a jar incompatability between the

axis jars and others. By others, I mean jars that contain javax.xml.*classes, and perhaps xerces related classes for parsing. I've done alotof fooling around with jar combinations, but I haven't been successfulSo I decided to look at the source code(org.apache.axis.message.MessageElement) for clues and now I'm even more

puzzled because it's not obvious how a casting exception is even
possible. Here's the relevent piece of code :

   public SOAPElement addTextNode(String s) throws SOAPException {
       try {
           Text text = getOwnerDocument().createTextNode(s);
           ((org.apache.axis.message.Text)text).setParentElement(this);
           return this;

The ClassCastException occurs in the line casting 'text' which isstrange because obviously a Text instance was obtained on the lineabove. This all smells like class version incompatabilites with the axiscritical jars, but I can't be sure. I'm fairly new to the axis world somy inexperience is getting in the way. I would appreciate any clues orinsights. Even if someone could confirm my suspicions about jar versionmismatches would be a step forward at this point and if possible a clueabout which classes are not compatable. I've included a full stackTracebelow in case it's helpful.

thanks and sorry for the crosspost to axis-users (I think I may haveposted to wrong group initially, so my apologies as I get oriented here)
