# 278 BPM API - Initiator Tasks

Here is my composite -

Here is the app link in Workspace

Now I want to initiate via the API.

First Kudos to Rommel Pino's post here

A great starting point -

Anyway - let's get a list of the Initiable Processes I have deployed, and then initiate the above process.

I create a project in jdev and include the following jars -

Code -

package initiatorapi;

import java.util.HashMap;
import java.util.List;

import java.util.Map;

import oracle.bpel.services.bpm.common.IBPMContext;
import oracle.bpel.services.workflow.client.IWorkflowServiceClient;
import oracle.bpel.services.workflow.client.IWorkflowServiceClientConstants;

import oracle.bpel.services.workflow.client.WorkflowServiceClientFactory;

import oracle.bpel.services.workflow.task.model.Task;

import oracle.bpm.client.BPMServiceClientFactory;

import oracle.bpm.services.client.IBPMServiceClient;
import oracle.bpm.services.instancemanagement.IInstanceManagementService;
import oracle.bpm.services.processmetadata.IProcessMetadataService;
import oracle.bpm.services.processmetadata.ProcessMetadataSummary;

            IBPMContext bpmContext = getIBPMContext("weblogic", "welcome1");
            List initiableTasks =
                service.getInitiatableProcesses(bpmContext);
            for (ProcessMetadataSummary pms : initiableTasks) {
                System.out.println(pms.getProjectName() + "/" +
                                   pms.getProcessName());

}

Test a couple of times -

I now log in to workspace as weblogic -

Now let's check the roles for this process -

Test the API with jstein/welcome1

I change the method so as to pass in user/pwd -

Re-test -

None found!

I can now expose this class as a web service -

I add the following jars -

So my libraries are as follows -

and deploy to WLS

Test

Login to workspace as jcooper
