Hi Alessio Thanks for the reply. No I create the SOAP message by getting an instance of the SOAP MessageFactory and then adding elements to the body. When i use the SoapMessage writeTo method to a file, it contains no CRLF pairs, but when I intercept the message using WireShark, I see the CRLF's. So it seems as if the SOAPConnection call method or underlying transport is adding the CRLF's Using the exact same code in GlassFish, the CRLF's are never added and it works fine, but I do not want to use GlassFish Regards Alfred View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4243955#...
