Gentlemen,

I am trying to use SUN's SAAJ1.3 libraries on IBM's JDK/Websphere 6.1 since Apache CXF webservices uses it. In order to do this I have to endorse those SAAJ1.3 libraries on Websphere under <WAS_INSTALL_ROOT>\java\jre\lib\endorsed. When this is done, WAS 6.1 throws the following error -

Caused by: java.lang.NoClassDefFoundError: com/sun/xml/messaging/saaj/soap/SOAPDocumentImpl
at com.sun.xml.messaging.saaj.soap.SOAPPartImpl.<init>(SOAPPartImpl.java:119)

SOAPDocumentImpl is part of saaj-impl, but it extends DocumentImpl from Sun's internal copy of Xerces! This explains the problem I am seeing with IBM's JDK. In order to resolve this issue, it requires adding the JAXP-ri-1.4.2 dependency in pom.xml -

<dependency>
<groupId>com.sun.xml.parsers</groupId>
<artifactId>jaxp-ri</artifactId>
<version>1.4.2</version>
<scope>test</scope>
</dependency>

So this is the recommended/universal approach to have the SUN's SAAJ libraries run on IBM JDK. However this breaks the OpenSAML 2.0 requirement to not use SUN's JAXP libraries and instead endorse it with their own xerces, xalan and xml-apis. Because of this restriction, all Webservice implementation- AXIS2, Apache CXF, SUN's JWSDP are breaking and thus cannot use OpenSAML 2.0. Has anyone run into this issue before and if yes what are the suggested means to address this problem.

thanks in advance
Sid
