Issue with modifying mesage via interceptor
Hi Colm,
I recently tried to modify the soap prefixes using an interceptor and a
setcontent method for message. I thought this will update the message but it
appears that it is not doing that.Take a look at the code you can try this
interceptor on any client request.
I choose this phase as at PRE-STREAM I get encrypted message.if you have
any examples that show how to modify the message (raw) that would be
Great!.Thanks for all your help.

Aki the .Net Service I am calling requires specific prefix and namesapaces
removed
I did this finally with the code below.however there are additional two
namespaces of parent node appearing in child node at some phase when
ws-policy is being applied.I would like them removed
I am not what phase i can remove those. This seems to be the only issue
remaining for me
I have fixed the prefix and namespaces for envelop and body using code
below.
<ExecuteRequest xmlns="http://www.xxx.gov/2008/09"
xmlns:s="http://www.w3.org/2003/05/soap-envelope"

SOAPPart soapPart = sm.getSOAPPart();
SOAPEnvelope soapEnv = soapPart.getEnvelope();

soapEnv.addNamespaceDeclaration("s",

Hi,
Treating a SOAP message as a plain text and manipulating its namespace
prefixes using the string-replacing operaiton is not a good idea. You
are likely to corrupt the message.
If your objective is to use different prefixes for certain standard
namespaces in your serialized SOAP message, you may want to look at
the approach mentioned in the mail thread
