Axiom exception with inline comments in the SOAP request

[teltmn9]

We are developing a web service with Axiom as the message factory, but we see strange Axiom exception being thrown with inline comments. Why is Axiom throwing exception in WebSphere 6.1 when a SOAP message contains an inline comment? If the comment occurs after the soap envelop, the request works properly in Axiom. But any inline comment would cause Axiom message factory to throw exception.

The same request worked with DomPOX but not with AXIOM as the message factory. I provided the actual request and websphere log below.

Please help.

[teltmn9]

Have you experience the same issue?

[Chris]

I have also encounter this, is is cause by a bug in Axiom, see:

https://issues.apache.org/jira/browse/WSCOMMONS-340

[jonnybbb]

Is there a way in spring-ws to remove the comments from an incoming request, when using axiom?

[Chris]

You could use one of these if an XSLT tranform can remove comments:
