Error using a standalone ws proxy

[Former Member]

Hi there,

I'm trying to create a client application which calls a webservice but I'm getting an error during the client run.

So Here is what I've done:

- Created /Deployed a WebServcie (running correctly)

- Created a Standalone Web Service Proxy.

- Deployed the Standalone WSProxy

- Included the Jar (from the generated Proxy) into my client app

- Added the created bin files from the proxy to the client app

- Added all classpath variables to my client project (I got from the proxy project)

- Trying to run the WS test client

Getting follwing error message:

=============================

What am I doing wrong?

Why can't the libraries be loaded?

Are you sure?

Do you still think it depends on the classpath?

I can also import files like:

com.sap.engine.services.webservices.jaxrpc.wsdl2java.features.builtin.SessionProtocol

so there shouldn't be a classpath prob I guess.

Hi Daniel,

According to my knowledge, we can only import those classes which either itself or JAR file containing them are in classpath.

Hi Daniel,

What do you mean by "deployed the Standalone Proxy"?

Standalone proxies are meant to be used in standalone applications, i.e. applications that do not run on the engine.

If you need to deploy a WS Client Proxy on the engine you have to use a Deployable Proxy for that purpose.

If you want to use a proxy, the steps you should follow are:

1. Generate the proxy

2. Go to the WS Perspective, the appropriate explorer view where the application that will use the proxy is. For standalone proxies this is the Java Explorer.

3. Right click and select "Add Client API" and select the WS Proxy project in the popup - this will add classpath references to all required JAR files

After this you should not receive any further classpath problems.

More information how to work with WS Proxies can be found in the development manual:

For standalone proxies:

For deployable proxies:

Yes...

It is working now.

And?

Yes you have been right all the time.

The problem is: A single reference in the classpath is not sufficiently. After putting all files into my lib/ext directory it was working.

Thanks again.

Daniel

Still get the same error...

Got all required files in my classpath (wouldn't be able to build the project without them).

Still don't understand it.

Thanks for the try.

I really hope someone can help me out.

My code of the client app:

import java.rmi.RemoteException;

import javax.xml.rpc.ServiceException;

import com.dcx.mcg.itp.aa.projects.eeim.proxy.EEIMDataService;
import com.dcx.mcg.itp.aa.projects.eeim.proxy.EEIMDataServiceImpl;
import com.dcx.mcg.itp.aa.projects.eeim.proxy.EEIMDataServiceViDocument;

public class TestWS
{

	public static void main(String[] args)
	{



		try
		{
			EEIMDataService service = new EEIMDataServiceImpl();				
			EEIMDataServiceViDocument port = 
				(EEIMDataServiceViDocument) 
				service.getLogicalPort("EEIMDataServiceConfPort_Document",EEIMDataServiceViDocument.class);
			
			String result = port.sayHello();
							
			System.out.println( "result  [.echoString]:" +result);
		}
		catch (RemoteException e)
		{
			e.printStackTrace();
		}
		catch (ServiceException e)
		{
			e.printStackTrace();
		}
		catch (Exception e)
		{
			e.printStackTrace();
		}
	}
}

Hi Daniel,

This is surely a classpath problem, check again that all

Library(.jar's) files are in classpath.
