Writing workflow method while using Workflow Manager (no Process Builder environment)

Hi,

In the Process Builder development guide I see the following:

"To write a workflow-specific method, write a Java class that extends the abstract class WorkflowMethod, which is defined in the bpmutil.jar file in the DOCUMENTUM_SHARED directory. Your class must implement the doTask( ) method that performs the main action of the class."

Currently I am still using Workflow Manager because Process Engine/Process Builder is not yet ready. Can I use the same approach to create a workflow method by extending the abstract class WorkflowMethod? Do you think the bpmutil.jar file (in the DOCUMENTUM_SHARED directory) exists without Process Engine/Process Builder environment? If not, how do write a workflow method when just using Workflow Manager?

Please share your knowledge and experiences for figuring this out.

Thanks.

Implement interface "com.documentum.mthdservlet.IDmMethod" which is available in "mthdservlet.jar" and define method

"public void execute(Map map, OutputStream outputStream) throws Exception"

Better to implement as the method as a BOF module as it will be simpler to deploy, espically in multi node production env.

You can use this as a base....

import java.io.PrintWriter;

import com.documentum.bpm.rtutil.WorkflowMethod;

import com.documentum.fc.client.IDfCollection;

import com.documentum.fc.client.IDfSession;

import com.documentum.fc.client.IDfSysObject;

import com.documentum.fc.client.IDfWorkitem;

import com.documentum.fc.common.DfException;

import com.documentum.fc.common.IDfProperties;

public abstract class SimpleWorkflowMethod extends WorkflowMethod {

protected IDfWorkitem workItem;

protected IDfProperties activityParameters;

void doInitialization(IDfWorkitem workitem, IDfProperties activityParameters) {

this.workItem = workitem;

this.activityParameters = activityParameters;

}

// @Override

protected final int doTask(IDfWorkitem workitem, IDfProperties properties, PrintWriter printwriter) throws Exception {

doInitialization(workitem, properties);

return doWorkflowTask(workitem, properties,printwriter);

}

abstract int doWorkflowTask(IDfWorkitem workitem, IDfProperties properties, PrintWriter printwriter) throws Exception;

protected IDfSession getSession() {

return this.workItem.getSession();

}

protected String getParameterAsString(String parameterName) throws DfException {

return this.activityParameters.getString(parameterName);

}

protected IDfSysObject getObjectFromPackage() throws DfException {

//System.out.println("Entered getObjectFromPackage");

IDfCollection pkgColl = null;

pkgColl = this.workItem.getAllPackages("r_object_id");

try {

if (pkgColl != null) {

// Iteratie van de package

while (pkgColl.next()) {

// We tellen het aantal documenten in een specifieke package

int docCount = pkgColl.getValueCount("r_component_id");

// We gaan elk document in de package itereren in praktijk is dit normaal altijd een formulier

for (int i = 0; i <= (docCount - 1); i++) {

//System.out.println("iterating components.... " + i);

IDfSysObject doc = (IDfSysObject) getSession().getObject(pkgColl.getRepeatingId("r_component_id", i));

return doc;

}

break;

}

} finally {

if (pkgColl != null)

pkgColl.close();

}

return null;

}

And then to actually create a workflow method...

import java.io.PrintWriter;

import com.documentum.fc.client.IDfWorkitem;

import com.documentum.fc.common.IDfProperties;

/**

* Does nothing

* @author Petros Giakouvakis

public class ApxAutoNoop extends SimpleWorkflowMethod {

protected int doWorkflowTask(IDfWorkitem workitem, IDfProperties activityParameters, PrintWriter arg2) throws Exception {

//Here you write your code

return 0;

}

To deploy it: compile it into a jar and create a new method using the Documentum Administrator.... and as verb you point to the class.

if i used extends DfSingleDocbaseModule implements IDfMethod, IDfModule will it work?
