Hi,
I posted the following ticket on the WebSphere user's forum and I thought
I'll be posting it here as well.
Hello,
This post is meant to illustrate a WAS 9.0.0.3 issue when using JAX-RS 2.0
with Apapche CXF 3.1.11.
The issue consists in raising the following exception:
[31/05/17 11:14:31:120 CEST] 000000a1 ServletWrappe E
com.ibm.ws.webcontainer.servlet.ServletWrapper init SRVE0271E: Uncaught

while bootstraping the resources in the following code:
@ApplicationPath("services")
public class App extends Application
{
}
Interesting enough, if web.xml is used instead of annotations, as in the
example below:
<servlet>
<servlet-name>CXFServlet</servlet-name>
<servlet-class>org.apache.cxf.jaxrs.servlet.CXFNonSpringJaxrsServlet</servlet-class>
<init-param>
<param-name>javax.ws.rs.Application</param-name>
<param-value>fr.simplex_software.tests.TestServiceImpl</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>CXFServlet</servlet-name>
<url-pattern>/services/*</url-pattern>
</servlet-mapping>
then everything works as expected.
The included WAR contains a very simple REST service with only one endpoint.
In order to experience the issue perform the following operations:
1. Clone the following repo using the command:
git clone
https://github.com/nicolasduminil/JAX-RS-2.-WebSphere-9-issue.git
2. Build the WAR using the command:
mvn -DskipTests clean package
3. Deploy the created WAR on WAS 9.0 and start the application using the
admin console or any other method you prefer
4. Run integration tests using the command:
mvn failsafe:integration-test
The following assertion failure will be observed:
java.lang.AssertionError: expected:<200> but was:<500>
at
fr.simplex_software.tests.ITest123.testMultipart2(ITest123.java:33)
and the full stack trace will be displayed in the server log file
Now, to confirm that using web.xml instead of annotations works, do the
following:
1. Switch on the develop branch:
git checkout develop
2. Perform the remaining operations as above
One detail to be noted is that the WAR is including Apache CXF 3.1.11
artifacts. Then the WAS parent-last class-loading strategy should be used.
However, during the tests it appeared that using the parent-first or the
parent-last strategy doesn't change anything.
The same as far as the variable
com.ibm.websphere.jaxrs.server.DisableIBMJAXRSEngine is concerned.
Another interesting point is that it appears that using the Apahce CXF
provided with WAS 9.0, which is 3.0.3, and consequently not including the
libraries in the WAR,
works as expected as well.
