Davanum Srinivas resolved AXIS-1903:
------------------------------------
Resolution: Fixed
I added a catch for java.lang.IncompatibleClassChangeError and used the patched
code inside that. Would that work? Please latest CVS.
thanks,

> IncompatibleClassChangeError when deploying Axis 1.2-RC3 on WebSphere 5.1
> with PARENT_FIRST classloading
> --------------------------------------------------------------------------------------------------------
>
> Key: AXIS-1903
> URL: http://issues.apache.org/jira/browse/AXIS-1903
> Project: Axis
> Type: Bug
> Components: SAAJ
> Versions: 1.2RC3
> Environment: WebSphere 5.1.x on Linux (2.4.x kernel).
> Reporter: David Tompkins
> Priority: Blocker
>
> I am deploying Axis 1.2RC3 in a war that resides within an ear. The axis jars
> are in the war/WEB-INF/lib dir. For various reasons related to the other
> contents of my ear, I must use PARENT_FIRST classloading. As many have
> reported, if you have PARENT_FIRST classloading on WebSphere 5.1 with Axis
> 1.2RC3, then there is a conflict between the version of saaj (1.1) that ships
> with WebSphere, and the version of saaj (1.2) that Axis 1.2RC3 expects, and
> you get the following exception:
>
> java.lang.IncompatibleClassChangeError: class org.apache.axis.SOAPPart does
> not implement interface org.w3c.dom.Document
>
> This issue can be resolved with PARENT_LAST classloading and a manifest which
> specifies the classpath...but for those of use who can't use PARENT_LAST
> classloading, there is another option.
>
> It appears that a single source code change to Axis will eliminate the issue
> altogether. The offending code is in
> org.apache.axis.message.MessageElement.addTextNode(), and can be patched as
> follows:
>
> OLD CODE:
>
> public SOAPElement addTextNode(String s) throws SOAPException {
> try {
> Text text = getOwnerDocument().createTextNode(s);
> ((org.apache.axis.message.Text)text).setParentElement(this);
> return this;
> } catch (ClassCastException e) {
> throw new SOAPException(e);
> }
> }
>
> PATCHED CODE:
>
> public SOAPElement addTextNode(String s) throws SOAPException {
> try {
> Text text = new org.apache.axis.message.Text(s);
> this.appendChild(text);
> return this;
> } catch (ClassCastException e) {
> throw new SOAPException(e);
> }
>
> After making this change, Axis 1.2RC3 will run on WebSphere 5.1 with
> PARENT_FIRST classloading, and no exceptions will be thrown.
