How to start a process using BPM API

1. Create a class like the one below, containing a method for starting BPM process, using BPM Api

package <Package_Name>;

import java.net.URI;
import java.util.Map;
import java.util.Set;
import com.sap.bpm.api.BPMFactory;
import com.sap.bpm.pm.api.ProcessDefinition;
import com.sap.bpm.pm.api.ProcessDefinitionManager;
import com.sap.bpm.pm.api.ProcessStartEvent;
import com.sap.bpm.pm.api.ProcessStartManager;
import commonj.sdo.DataObject;
import commonj.sdo.Property;

public class ProcessStarter {

private ProcessDefinitionManager processDefinitionManager;
private ProcessDefinition processDefinition;
private ProcessStartManager processStartManager;
private Set<ProcessStartEvent> processStartEvents;
private ProcessStartEvent processStartEvent;
public ProcessStarter(String vendor, String dcName, String processTechnicalName) {
this.processDefinitionManager = BPMFactory.getProcessDefinitionManager();
this.processStartManager = BPMFactory.getProcessStartManager();
this.processDefinition = processDefinitionManager.getActiveProcessDefinition(vendor, dcName, processTechnicalName);

 }

public DataObject getProcessStartDataObject(){
this.processStartEvents = processStartManager.getProcessStartEvents(processDefinition.getId());
this.processStartEvent = processStartEvents.iterator().next();

 DataObject sdo = processStartManager.createDataObjectForStartEvent(this.processStartEvent); 

return sdo;
 }


public URI startProcess(DataObject dataObject) throws BPMProcessStartException{
try {
return processStartManager.startProcess(this.processStartEvent, dataObject);
 } catch (Exception e) {
throw new BPMProcessStartException("Could not start process: "+ e.getMessage() , e);
 }
 } 
}

2. Create an instance from the above class:

ProcessStarter starter = new ProcessStarter("<Vendor-Name>", "<DC-Name>", "<Process-Name>");

3. Set process input data:

DataObject startSDO = starter.getProcessStartDataObject();
DataObject processInput = startSDO.getDataObject("StartProcess");
 processInput.set("engDepartment",”VALUE”);
 processInput.set("itemNo", “VALUE”);
 processInput.set("orderNo", “VALUE”);

processInput.set("organization",”VALUE”);
 processInput.set("processType", “VALUE”);
 processInput.set("requestNo", “VALUE”);

processInput.set("requestorId", “VALUE”);
URI processInstanceId = starter.startProcess(startSDO);
