First of all thanks for reading and reviewing my problem and suggesting the possible strategy to solve this issue. I will be trying this right away and will provide you the feedback soon.
Here are my thoughts. see in JBPM engine level we have this object which I have defined which is data model and the same will act as the object to invoke the cxv dynamic client apis. I checked the dynamic apis it takes in the object and then it creates the MessagePart and creates the soap message and then post it to the webservice. it should work I had tried different style of cxf clients they work all fine. I created a simple client with just the DTO as the object and passed to client.invoke( , obj)
pardon me if my understanding is little not clear. why you think that class is not the right one which webservice expects. ? if you see that com.xxx.mdsoasis.OasisNotificationCtlDto and com.xxx.mdsoasis.OasisNotiicationCtlDto are exact class names which it is comparing. I debugged and I saw the issue right there in the cxf apis I am not sure what the problem is I believe its the classloader issue.
CXF Mentions : The JaxWsDynamicClientFactory sets the Thread context ClassLoader to a new ClassLoader that contains the classes for the generated types. If you need the original ClassLoader, make sure you save it prior to calling createClient.
If i see closely the code in WebServiceWorkItemHandler out of the box i see that this same DTO will work if we follow above note provided by them, I am not so expert on class loaders but I am thinking to extend the work item and see if I can make it flexible WebService Task. which work the way I wanted to invoke with out runing wsconsume. but lets see how far i would be successful. I have some deadlines as well.
Summarize .
1. Go ahead and pack classes which i get from wsconsume and test
2. Have steps to extend exisitng webServiceWorkItemHandler in order to liverage from the advanced CXF WSDynamic Factory class.
Currently if we fix the class loading issue in the before calling the createClient will solve this issue and we can use the same DTO whic is the process level to pass as Parameter to the web operation.
Look at the JIRA which I have logged at the CXF Jira , actually I wanted to share the information which I have captured and where exactly the issue happens. I cannot conclude that it is a error becuase may be WebServiceWorkItemHandler. is not calling or using the CXF apis correctly and hence they are not working also the name of the classes are same but as they come from different class loaders they are having issue.

** I just wanted to share the information , I myself not sure on the things but thought if we share probably you might look at it might get some conclusive rationalization for the above issue.
Thanks again for looking at the post and answering it
look at the debugger below
This method is inside the CXF Apis , I will update the post with the class name
Class Name : ClientImpl
private void checkPart(MessagePartInfo part, Object object) {
if (part == null || part.getTypeClass() == null || object == null) {
return;
}
Class<?> typeClass = part.getTypeClass();
if (typeClass == null) {
return;
}
if (typeClass.isPrimitive()) {
if (typeClass == Long.TYPE) {
typeClass = Long.class;
} else if (typeClass == Integer.TYPE) {
typeClass = Integer.class;
} else if (typeClass == Short.TYPE) {
typeClass = Short.class;
} else if (typeClass == Byte.TYPE) {
typeClass = Byte.class;
} else if (typeClass == Character.TYPE) {
typeClass = Character.class;
} else if (typeClass == Double.TYPE) {
typeClass = Double.class;
} else if (typeClass == Float.TYPE) {
typeClass = Float.class;
} else if (typeClass == Boolean.TYPE) {
typeClass = Boolean.class;
}
} else if (typeClass.isArray() && object instanceof Collection) {
//JAXB allows a pseudo [] <--> List equivalence
return;
}
if (!typeClass.isInstance(object)) {
throw new IllegalArgumentException("Part " + part.getName() + " should be of type "
+ typeClass.getName() + ", not "
+ object.getClass().getName());
}
}
I Now I may be totally wrong but just thinking load and sharing information as i said.
Do you think that something can be done in below so that I dont have to create the classes. I have observed in debugger that control doesnt not go beyond italics and bold how come client is already inside the clients map object ??
this is another mystery I am not able to resolve when I run the debugger.
protected synchronized Client getWSClient(WorkItem workItem, String interfaceRef) {
if (clients.containsKey(interfaceRef)) {
return clients.get(interfaceRef);
}
String importLocation = (String) workItem.getParameter("Url");
String importNamespace = (String) workItem.getParameter("Namespace");
if (importLocation != null && importLocation.trim().length() > 0
&& importNamespace != null && importNamespace.trim().length() > 0) {
Client client = dcf.createClient(importLocation, new QName(importNamespace, interfaceRef), getInternalClassLoader(), null);
clients.put(interfaceRef, client);
return client;
}
long processInstanceId = ((WorkItemImpl) workItem).getProcessInstanceId();
WorkflowProcessImpl process = ((WorkflowProcessImpl) ksession.getProcessInstance(processInstanceId).getProcess());
List<Bpmn2Import> typedImports = (List<Bpmn2Import>)process.getMetaData("Bpmn2Imports");
if (typedImports != null ){
Client client = null;
for (Bpmn2Import importObj : typedImports) {
if (WSDL_IMPORT_TYPE.equalsIgnoreCase(importObj.getType())) {
try {
client = dcf.createClient(importObj.getLocation(), new QName(importObj.getNamespace(), interfaceRef), getInternalClassLoader(), null);
clients.put(interfaceRef, client);
return client;
} catch (Exception e) {
logger.error("Error when creating WS Client", e);
continue;
}
}
}
}
return null;
}
Thanks
