NoClassDefFoundError: com/sapportals/wcm/repository/ResourceException

Hi All,

i want to access a KM resource (an excel file to be specific) using webdynpro. for this, i am trying to access it's parent folder first...

So, i have written the following line of code in the View's wdInit method::

My NDS's version is 7.0.11.

	//get XLS file from KM	-- "/documents/Test/myfile.xls"

		com.sapportals.portal.security.usermanagement.IUser sapUser = null;
		try {
			IWDClientUser wdClientUser = WDClientUser.getCurrentUser();
			sapUser = (com.sapportals.portal.security.usermanagement.IUser) wdClientUser.getSAPUser();
		} catch (WDUMException e1) {
			wdComponentAPI.getMessageManager().reportSuccess("Got an exception1234::");
		}

		IResourceContext resContext = new ResourceContext(sapUser);
		ICollection parent = null;
		IResourceFactory factory = null; 
		RID rid_parentFolder = null; 
		try {
			rid_parentFolder = RID.getRID("/documents/Test");
			factory = ResourceFactory.getInstance();
			parent = (ICollection) factory.getResource(rid_parentFolder, resContext);
		} catch (ResourceException e2) {
			wdComponentAPI.getMessageManager().reportSuccess("Got an exception1235::");
			e2.printStackTrace();
		}  

But, i am getting this error:

500 Internal Server Error			
		SAP NetWeaver Application Server 7.00/Java AS 7.00

See full exception chain for details. 

Correction Hints	
It can't be determined from the exception chain, which class loader failed to load the above class. But at least the class loader of the current application does not contain a resource with name 'com/sapportals/wcm/repository/ResourceException'. 
Note: the above hints are only a guess. They are automatically derived from the exception that occurred and therefore can't be guaranteed to address the original problem in all cases.

I found that this class is in <i>_webdynpro_services.jar</i> .. My system administrator told me that the <i>_webdynpro_services.jar</i> file on the server is different from the file on my developing system.

I even tried replacing the server jar with the jar from my system .. but in vain

Is there any folder on the server we have to put in the JAR ?????

plz let me know..

Any input is highly appreciated.

Thanx.
