Service classloader problem
---------------------------
Key: AXIS2-537
URL: http://issues.apache.org/jira/browse/AXIS2-537
Project: Apache Axis 2.0 (Axis2)
Type: Bug
Components: core, deployment
Versions: 0.95
Environment: Bea Weblogic 8.1 SP5, All OS, Java 1.4.2_05
Reporter: Dmitriy Kiriy
I have axi2.war\WEB-INF\services\AssetService.aar
in that file I have:
org/apache/axis2/
AssetServiceStub.class
AssetServiceStub$1.class - AssetServiceStub$30.class
AssetServiceSkeleton.class
AssetServiceMessageReceiverInOut.class
AssetServiceCallbackHandler.class
com.mypackage/
AssetServiceImpl (extends AssetServiceSkeleton)
META-INF/
services.xml
AsserService.wsdl
(<parameter locked="false" name="ServiceClass">
com.mypackage.AssetServiceImpl
</parameter>)
All classes excluding com.mypackage.AssetServiceImpl was generated by WSDL2Java
tool.
We have a class loading problem. So, I little bit change
AbstractMessageReceiver.java:
protected Object makeNewServiceObject(MessageContext msgContext) throws
AxisFault {
try {
AxisService service =
msgContext.getOperationContext().getServiceContext().getAxisService();
ClassLoader classLoader = service.getClassLoader();
Parameter implInfoParam = service.getParameter(SERVICE_CLASS);
if (implInfoParam != null) {
try {
Class implClass = classLoader.loadClass(((String)
implInfoParam.getValue()));
return implClass.newInstance();
} catch (Throwable e)
{
System.err.println("While tring to load class "+(String)
implInfoParam.getValue()+" got the following problem: "+e);
e.printStackTrace(System.err);
throw AxisFault.makeFault(new Exception(e));
}
} else {
throw new AxisFault(Messages.getMessage("paramIsNotSpecified",
"SERVICE_CLASS"));
}
} catch (Exception e) {
throw AxisFault.makeFault(e);
}
}
So, in lines:
System.err.println("While tring to load class "+(String)
implInfoParam.getValue()+" got the following problem: "+e);
e.printStackTrace(System.err);
throw AxisFault.makeFault(new Exception(e));
I got:
While tring to load class com.mypackage.AssetServiceImpl got the following
