My goal is to call a service from a java servlet.

Here is the code I wrote in my servlet,

            try{
                     //Set connection properties required to invoke LiveCycle ES Properties
                          Properties connectionProps = new Properties();
                          connectionProps.setProperty(ServiceClientFactoryProperties.DSC_DEFAULT_EJB_ENDPOINT,
                               "t3://xxx.xxx.52.67:7001");
                          connectionProps.setProperty(ServiceClientFactoryProperties.DSC_TRANSPORT_PROTOCOL,
                               ServiceClientFactoryProperties.DSC_EJB_PROTOCOL);    
                          connectionProps.setProperty(ServiceClientFactoryProperties.DSC_SERVER_TYPE,
                               "WebLogic");
                          connectionProps.setProperty(ServiceClientFactoryProperties.DSC_CREDENTIAL_USERNAME,
                               "administrator");
                          connectionProps.setProperty(ServiceClientFactoryProperties.DSC_CREDENTIAL_PASSWORD,
                               "xxxxxxxx");
                                              
                     //Create a ServiceClientFactory object
                     ServiceClientFactory myFactory = ServiceClientFactory.createInstance(connectionProps);
                                                  
                     //Create a ServiceClient object
                     ServiceClient myServiceClient = myFactory.getServiceClient();
                    
                     //Create a Map object to store the parameter value
                     Map params = new HashMap();
                                                           
                     //Create an InvocationRequest object
                     InvocationRequest esRequest =
                     myFactory.createInvocationRequest(
                     "http://xxx.xxx.52.67:9080/rest/services/AQUO_STEVEN/Processes/RenderEmployeePDF:1.0",
                     //Specify the LiveCycle ES process name
                           "invoke",          //Specify the operation name
                           params,                    //Specify input values
                           true);                     //Create a synchronous request
                                            
                     //Send the invocation request to the process and
                     //get back an invocation response object
                     InvocationResponse esResponse = myServiceClient.invoke(esRequest);
                     FormsResult formOut = (FormsResult)esResponse.getOutputParameter("RenderedForm");
                                      
                     //Create a Document object that stores form data
                     Document myData = formOut.getOutputContent();
                                
                     //Get the content type of the response and
                     //set the HttpServletResponse object's content type
                     String contentType = myData.getContentType();
                    
                     resp.setContentType("text/html;charset=UTF-8");
                                
                     //Create a ServletOutputStream object
                     ServletOutputStream oOutput = resp.getOutputStream();
                                
                     //Create an InputStream object
                     InputStream inputStream = myData.getInputStream();
                                
                     //Get the size of the InputStream object
                     int size = inputStream.available();
                                
                     //Create and populate a byte array 
                     byte[] data = new byte[size];
                     inputStream.read(data);
                                            
                     //Write the data stream to the web browser           
                     oOutput.write(data);
                                      
                      } catch (Exception e) {
                           e.printStackTrace();
                     }            

and

AQUO_STEVEN/Processes/RenderEmployeePDF:1.0 is the process I created in Adobe Workbench.

However, I get the following exception in the log file.

####<Mar 2, 2015 11:38:34 AM EST> <Notice> <StdErr>  <[ACTIVE] ExecuteThread: '3' for queue: 'weblogic.kernel.Default (self-tuning)'> <<WLS Kernel>> <> <> <1425314314630> <BEA-000000> <ALC-DSC-031-000: com.adobe.idp.dsc.net.DSCNamingException: Remote EJBObject lookup failed for ejb/Invocation provider>

where line 159 is this line,

InvocationResponse esResponse = myServiceClient.invoke(esRequest);

Can anyone give me some suggestions on how to fix this error?

thanks
