calling FlowExecutor.launch() manually. unexpected error

[tort]

For example, web application accepts SOAP method call, launches a flow and returns view name:

public class LoginServiceImpl extends ServletEndpointSupport implements LoginService{

@Override
protected void onInit() throws ServiceException {
//loading executor
this.executor = (FlowExecutorImpl)getWebApplicationContext().getBe an("flowExecutor");
}

public String startFlow(String flowName, long userId) throws RemoteException{
ResponseInstruction resp = executor.launch("AcceptClientFlow", new MockExternalContext());
String viewName = resp.getViewSelection().toString();

return viewName;
}
}

onInit runs well.
problem is that NPE occurs when calling executor.launch().

FlowExecutor, flowLocator and flow actions are in spring applicationContext.xml

may be using MockExternalContext is wrong?
please help to launch flow without HTTP

Could you post the stack trace?
Also, take a look at how the AbstractFlowExecutionTests are driving a FlowExecution.

sorry for being away.
it was my mistake, SWF works as expected.
