Hello I get this error in the browser while building a Soap message inside a 
web service:

I placed correctly endorsed libraries (dom3-xercesImpl-2.5.0.jar and 
dom3-xml-apis-2.5.0.jar) both inside %JAVA_HOME%\jre\lib\endorsed and inside 
%CATALINA_HOME%\common\endorsed.
If a build a SOAP message in a jsp page or in a stand alone java class I have 
no errors, but if I try to build a SOAP message inside the code of a web 
service I get the errors above.

My configuration is: j2sdk1.4.2_03 tomcat 5 and jwsdp-1.5.


Thank you in advance for a response.
