问题
I have an application that exposes web services for clients via CXF. This side of things works perfectly.
The application also needs to act as a client itself and contact other servers, this is where I am running into problems.
With "Parent First" classloading I get this:
Caused by: javax.xml.ws.WebServiceException: Error: Maintain Session is enabled but none of the session properties (Cookies, Over-written URL) are returned.

With "Parent last" classloading the application can't even expose its own services:
[23/06/15 15:33:12:985 BST] 000002d3 servlet E com.ibm.ws.webcontainer.servlet.ServletWrapper service Uncaught service() exception thrown by servlet cxf: java.lang.VerifyError: JVMVRFY013 class loading constraint violated; class=org/apache/cxf/jaxb/attachment/JAXBAttachmentUnmarshaller, method=getAttachmentAsDataHandler(Ljava/lang/String;)Ljavax/activation/DataHandler;, pc=0

at java.lang.J9VMInternals.verify(J9VMInternals.java:85)
at java.lang.J9VMInternals.initialize(J9VMInternals.java:162)
I have tried disabling WebShere's own JAXWS Engine via the WAR's manifest.mf and no matter what I try with "Parent last" classloading I always get some error like the above. A different class depending on what JAR I have moved or replaced, but always a verify error.
I have also gone through the official Apache documentation, various IBM guides, countless blog and forum posts to no avail. I am at my wit's end with this
The same WAR runs perfectly on Tomcat, JBoss and WebLogic.

Does anyone know how to get Apache CXF 2.7.11 on WebSphere 8.5 to be able to act as a server and as a client?
回答1:
We had the same problem using Was 8.5 (jdk 1.7_64), CXF, JAXB & xmlbeans:
JAXB is the default xml/java binding used by CXF. Was 8.5 uses endorsed JAXB api definition version 2.2.2 (in <WebSphere-dir>\AppServer\endorsed_apis\jaxb-api.jar) and standard implementation (in JRE rt.jar).
Xmlbeans 2.4.x holds inside org.w3c.* classes already present in Was (<WebSphere-dir>\AppServer\java_1.7_64\jre\lib\xml.jar).
In the end we solved so:
first following the instructions here: http://www.ibm.com/developerworks/websphere/library/techarticles/1001_thaker/1001_thaker.html
then deleting from our deploy the following jar:
- activation-*,
- stax-api-* (but not stax2-api!),
- jaxb-api-*,
- jaxb-impl-*,
- xercesImpl-*,
- xml-apis-*
last deleting all org.w3c classes inside xmlbeas-2.x.jar
This is a complete list of all thirdparty JAR files we are successfully using:
- cxf-*-2.7.11.jar
- dom4j-1.6.1.jar
- ehcache-2.8.2.jar
- ehcache-core-2.5.1.jar
- jettison-1.1.jar

- openws-1.5.1.jar
- spring-*-3.2.13.RELEASE.jar
- stax2-api-3.1.1.jar
- woodstox-core-asl-4.2.1.jar
- wsdl4j-1.6.3.jar
- wss4j-1.6.10.jar
- xml-resolver-1.2.jar
- xmlbeans-2.3.0-now3c.jar
- xmlpull-1.1.3.1.jar

- xmlsec-1.5.4.jar
- xmltooling-1.4.1.jar
- xpp3_min-1.1.4c.jar
- xstream-1.4.7.jar
We hope this is helpful.

PARENT_LAST: Maybe you have a third party library in your deployment with the javax.activation.DataHandler class. Try to remove the activation-1.1.jar from your deployment.
