Conversion of WFTs to WFMs

Surender

Hi,

I am trying to convert my WFT workflow to WFM workflow.
I have a requirement where I need to populate workflow name dynamically (by reading the properties file) based on the branch name.

This we can do in WFT by passing the branch name dynamically and reading the values from properties file.

I tried writing a datasource by hard coding the branch name in the datasource.
But my requirement is to pass the branch name on the fly to the datasource.

Does any body have implemented such functionality in WFM and how we can achieve this kind of functionality in WFM?

TeamSite 6.7.1 SP1 and WFM 1.0.0.1 and Solaris 10.

Thanks

will you be passing the name of:
1) the branch where the WF is being invoked?
2) some other branch?
If it is 1 then you can use csclient.getBranch() which will return CSBranch obj where the workflow is being invoked, do this from a preprocessor.

if it is 2 then you can enter the branch name in the instantiation form using either a text field or dropdown list with datasource.

Surender

Thanks Crsb for your reply.
we have more than 100 branches.
we dont want to allow the user to choose the branch in the instantiation form.

dont we have any other way to pass the branch name and read the properties file before the workflow has initiated?

My aim is to:

1. Read the properties file based on branch name and assign the workflow name dynamically.

Crsb

you didn't answer my question if it is 1 or 2?

you need to confirm if the branch name you want to get is the branch where the workflow is being invoked? in this case read #1 in my previous answer. You need to get branch name in preprocessor then read your properties file and set job name.

Surender

Thanks Crsb.
I misunderstood your previous post.
I got it now. The branch name is where the workflow is being invoked.
So I will go with your #1 suggestion. and I will post the result.

Thanks for your help.

Hi Crsb,

csclient.getBranch() requires a CSVPath object as a parameter.
how can I pass vpath?

[html]
CSBranch getBranch(CSVPath path, boolean validate)
Gets a CSBranch object based on the path provided.
[/html]

Crsb

If you are in preprocessor where you have (WFMWorkflow workflow) you can do something like this:


            String workarea = workflow.getParams().get("$IW_WORKAREA").toString();

            CSVPath waPath = new CSVPath(workarea);
        client.getBranch(waPath, true);

I know that code works, I dont have a way to test this but you can also try workflow.getParams().get("$IW_BRANCH");

Surender

Thanks for your help so far.

Now I have 2 problems.

1. how can I get a client object ?
2. once I get a client object how can I modify the workflow name? I didn't see any method or function of workflow object to modify the workflow name.

Here is my java code: still I am getting 2 errors
[html]
public class PreProcessAssignJobName implements InProcessJavaCommand
{
private static final Logger log = LoggerFactory.getLogger(WFJobNamePicker.class.getName());

public WFMWorkflow execute(WFMWorkflow workflow, Mapparams)
{

String branch = workflow.getParams().get("$IW_BRANCH").toString();
CSVPath waPath = new CSVPath(branch);

CSClient client;
CSBranch csbranch = client.getBranch(waPath, true);
String branch_name = csbranch.getName();

String jobname = "NULL";
if (branch_name != null)
{

try {

DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
Document doc = docBuilder.parse (new File("/interwoven/teamsite/local/config/wft/****/Production_Update.xml"));

// normalize text representation
doc.getDocumentElement ().normalize ();
log.debug("Root element of the doc is " + doc.getDocumentElement().getNodeName());

NodeList listOfBranches = doc.getElementsByTagName("branch");
int totalBranches = listOfBranches.getLength();
log.debug("Total no of Branches : " + totalBranches);

for(int s=0; s<listOfBranches.getLength(); s++){

Node firstBranchNode = listOfBranches.item(s);
if(firstBranchNode.getNodeType() == Node.ELEMENT_NODE){
Element firstBranchElement = (Element)firstBranchNode;
String name = firstBranchElement.getAttribute("name");
log.debug("name : "+name);
if (name.equals(branch_name))
{
jobname = firstBranchElement.getAttribute("job_name");
log.debug("jobname : "+jobname);
return workflow;
//return vPath;
}
}

}

}
catch (SAXParseException err) {
System.out.println ("** Parsing error" + ", line " + err.getLineNumber () + ", uri " + err.getSystemId ());
System.out.println(" " + err.getMessage ());
}
catch (SAXException e) {
Exception x = e.getException ();
((x == null) ? e : x).printStackTrace ();
}
catch (Throwable t) {
t.printStackTrace ();
}
}//if
else {
return workflow;
}
return workflow;
}

}

String branch = workflow.getParams().get("$IW_BRANCH").toString();

Does that line give the branch name/VPath? if yes, then why do you still need to client.getBranch()? you can get branch name from branch vpath.

2. once I get a client object how can I modify the workflow name? I didn't see any method or function of workflow object to modify the workflow name.

You are probably right, I know setName() is available with CSWorkflow and you have WFMWorkflow. You can try something like updateVariable(var name, value)... try to print out available workflow vars using workflow.getVariables(), if workflow name is one of them then you can use updateVariable().

Thanks Crsb. I will try that and post the result.

Hi Crsb,

I tried to print out the workflow variables using the below java code:
[html]
WFMNameValuePair[] arr = workflow.getVariables();
log.debug("start of workflow variables");
log.debug("array length: "+arr.length);
for (int i=0; i <arr.length; i++)
{
log.debug("Var "+i+":"+arr.getName());
log.debug("Var "+i+":"+arr.getValue());
}
log.debug("end of workflow variables");

[/html]

but I didn't get any worklfow variables, and I got the following output in the debug log.
[html]
2010-02-17 10:50:52,427 [http-8080-Processor24] DEBUG com.xx.datasource.PreProcessAssignJobName (abc) - start of workflow variables

any idea? how can I change workflow name?

...

I'd look at the other part if his response:

I know setName() is available with CSWorkflow and you have WFMWorkflow

The workflow name is not a variable, it is a property of the workflow itself - therefore setName() should (theoretically) be the way to change it.

Hi Crsb,
any idea? how can I change workflow name?

Do you have to change the name before the job starts? if you don't care if the workflow is already instantiated then you can change the job name from a URL task where the URL Task is the first task in the workflow. I just tested this code and it works:



package XXXXXX.XXXX.XXXX;

import com.interwoven.cssdk.common.CSClient;
import com.interwoven.cssdk.common.CSException;
import com.interwoven.cssdk.workflow.CSExternalTask;
import com.interwoven.cssdk.workflow.CSWorkflow;
import com.interwoven.cssdk.workflow.CSURLExternalTask;
import java.util.Hashtable;
import org.apache.log4j.Logger;

/**
 *
 * @author cb
 */

public class RenameJob implements CSURLExternalTask {
    private static Logger logger;

    public void execute(CSClient client, CSExternalTask task, Hashtable params) throws CSException {

        try {
            logger = Logger.getLogger(RenameJob.class);
         //   logger.setLevel(LoggingUtil.setLogLevel("debug"));
            logger.debug(">>> RenameJob.execute()");

            String branch = task.getArea().getVPath().getBranch().getBranchName();
            branch = branch.replaceAll(".*\\/", "");
            logger.debug("Branch: " + branch);
            CSWorkflow workflow = task.getWorkflow();
            logger.debug("current workflow name: " + workflow.getName());
            workflow.setName(branch + "_NewJobName");
            logger.debug("new workflow name: " + workflow.getName());


        } catch (Exception e) {
            logger.error("Exception RenameJob.execute() at :" + e);
            e.printStackTrace();
        } finally {
            logger.debug("<<< RenameJob.execute()");
            task.chooseTransition("", "Renamed JOb");
        }
    }
}

If you have to do it before the workflow is instantiated then I don't know of straight way to do but it will be possible using nested workflows.

Surender

That is the only way (URL Task) I can think of now.

Surender

Through URL Task I can able to modify my WF name.
Thanks Crsb.
