Subject [jira] [Commented] (AXIS2-2972) Vague error produced for ServiceClient invocation within a service where class pathing is a problem
Date Fri, 10 Jun 2011 10:37:59 GMT

    [ https://issues.apache.org/jira/browse/AXIS2-2972?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13047126#comment-13047126

Deepak Pant commented on AXIS2-2972:
------------------------------------

I was able to fix this issue by doing following: (WebSphere 7.0.0.17 and Apache Axis2 1.5.4)

(a) WebSphere Console: Under "Class loading and update detection", selected following two
options: Classes loaded with local class loader first (parent last) and Single class loader
for application.
(b) WebSphere Console: Under "Manage Modules" for both the WAR file(s) present in the EAR,
selected "Classes loaded with local class loader first (parent last)" option.
(c) Removed following files from WEB-INF/lib of my WAR files: xalan-2.7.0.jar, xercesImpl-2.6.2.jar,
xercesImpl-2.8.1.jar, xml-apis-1.3.02.jar
(d) Added following via Ant to MANIFEST.MF file of the WAR file.
<attribute name="DisableIBMJAXWSEngine" value="true"/>
(e) Bundled "commons-logging-adapters-1.1.1.jar" file instead of commons-logging-1.1.1.jar.
(f) Forcefully included "org.apache.axis2.jar" file present under "/IBM/WebSphere/AppServer/plugins"
folder in the EAR/lib folder. Forced it to be the first file in MANIFEST.MF file of the EAR
file.

Once WebSphere is happy... life is good...

> The problem I have seen occurs when a component is not in the deployment directory, but
is being referenced externally. Instead of encountering a ClassNotFoundException or similar,
a vague error is produced when attempting to:
> 1) create a ServiceClient within a service
> 2) load a configuration context within a service
> The client was external to the jar because it will be used both remotely and as a part
of the service. The text of the exception is misleading because the receivers in use as per
the services.xml have nothing to do with those seen in the error.
> To create the error, simply attempt to create a new ServiceClient() in a class that is
not contained within the deployment directory, but is referenced by a class in the deployment
directory.
> The error seen is the following:
> java.lang.ClassCastException: org.apache.axis2.receivers.RawXMLINOnlyMessageReceiver
