Grzegorz Grzybek commented on CXF-5385:
---------------------------------------
I wonder why 2.7.3 works and 2.7.4 not - these both version use
{{javax.ws.rs-api-2.0-m10.jar}} as JAX-RS API.
However I've tested your scenario and encountered two problems:
JAX-RS conflict:
{noformat}
java.lang.NoSuchMethodError:
javax/ws/rs/NotFoundException.validate(Ljavax/ws/rs/core/Response;Ljavax/ws/rs/core/Response$Status;)Ljavax/ws/rs/core/Response;
{noformat}
Commons XmlSchema conflict:
{noformat}
java.lang.NoSuchMethodError:
org/apache/ws/commons/schema/XmlSchemaCollection.read(Lorg/w3c/dom/Document;Ljava/lang/String;)Lorg/apache/ws/commons/schema/XmlSchema;
{noformat}
That's because the above classes are provided by WebSphere 8.5 (regardless of
setting the _parent-last_ class loader):
* {{WAS_HOME/plugins/javax.j2ee.jaxrs.jar}}
* {{WAS_HOME/plugins/org.apache.axis2.jar}}
respectively.
What has worked for me is this:
# console → Environment → Shared Libraries - I've created the shared library
called "JAX-RS" with two JARS:
#* {{M2_REPO}}/javax/ws/rs/javax.ws.rs-api/2.0-m10/javax.ws.rs-api-2.0-m10.jar
#*
{{M2_REPO}}/org/apache/ws/xmlschema/xmlschema-core/2.0.3/xmlschema-core-2.0.3.jar
# Check the "Use an isolated class loader for this shared library" option
# console → Applications → WebSphere enterprise applications → _your
application_ → Shared library references - I've checked the WAR module, clicked
_Reference Shared Libraries_ and added the "JAX-RS" library to the WAR module.
# restart WebSphere (you can't do much in WAS without restarting...)
And everything works!
