Java class must implement IDmMethod interface

lek

We try to create custom method server to follow user requirement.

Custom method server implement IDmMethod.

public class SampleMethod implements IDmMethod {

....

public void execute(Map params, OutputStream arg1) throws Exception {

initWorkflowParams(params);

IDfSessionManager sessionManager = login();

try

{

IDfId workitemID = new DfId(m_workitemId);

session = sessionManager.getSession(m_docbase);

//String smtp = session.getServerConfig().getString("smtp_server");

IDfWorkitem workitem = (IDfWorkitem)session.getObject(workitemID);

//IDfWorkflow workflow = (IDfWorkflow)session.getObject(workitem.getWorkflowId());

if (workitem.getRuntimeState()==IDfWorkitem.DF_WI_STATE_DORMANT)

workitem.acquire();

System.out.println("Hello World");

workitem.complete();

}catch(Exception ex){

ex.printStackTrace();

}finally

{

if ( session != null )

sessionManager.release(session);

}

Our environment D6.7 sp2 , window 2008 server 64 bit.

We create workflow using workflow manager. In workflow we crate auto activity and use custom method. Then we run workflow , method server not work and we find error in server.log

Please consider moving this question as-is (no need to recreate) to the proper forum for maximum visibility. Questions written to the users' own "Discussions" space don't get the same amount of attention and can go unanswered for a long time.

You can do so by selecting "Move" under ACTIONS along the upper-right. Then search for: "Documentum" and select the first result that appears. This will relocate it to the Developer Network space of the Documentum community.

Try implementing IDfMethod. However the suggested way of creating a method is by creating a module.

BTW, have you configured the method to run as a workflow method?

Hi Alvaro

I have config method to Run as the server, Use method server and Use as workflow method.

You could try clear the work folder before starting up the method server

C:\Documentum\jboss5.1.0\server\DctmServer_MethodServer\work

Also make sure that you do not have only one mthdservlet.jar on your classpath.

HI Experts,

from your stacktrace i can see that you are using D6.7SP2.

i suppose to implement server method you should implement IDfMethod and not IDmMethod

( if i recall IDmMethod existed within methodServer.jar and was used in 5.X versions ==> please check becaus im not 100% sure of the version)

the IDfMethod interface exists in the dfc.jar so no need to include jar from server into your project.

You put wrong method into activity config.
