D2 Scheduled Workflow

Hello ,

While i was going through D2 4.1 API i came across a couple of methods in com.emc.d2fs.interfaces Interface IWorkflowService for launching workflow

1) launchScheduledWorkflow(Context context, java.lang.String id)

Launch a scheduled workflow.

launchWorkflow(Context context, java.util.List<Attribute> parameters)
Launch document into workflow

so what is difference between Scheduled workflow and Normal workflow , and in case if we use 2nd method ie.

launchWorkflow(Context context, java.util.List<Attribute> parameters)

Launch document into workflow

what are the parameters do we need to have in the java.util.List

I see you only do a request.getAttributes().add(attr); at the end?

You Attribute object is everytime overwritten in your code.

So the only item in your Attribute object should be buttonId = buttonOk.

Try it like this:

Attribute attr = new Attribute();

attr.setName("config");

attr.setType(2);

attr.setValue("myWorkflow");

request.getAttributes().add(attr);

attr = new Attribute();

attr.setName("workflow_label");

attr.setType(2);

attr.setValue("MyWorkflow");

request.getAttributes().add(attr);

attr = new Attribute();

attr.setName("reviewers");

attr.setType(2);

attr.setValue("mayur");

request.getAttributes().add(attr);

etc...

Hi,

And the javadoc is not helping on this..

Julien.Fontaine

Which Javadoc ?

Antal Bos

A scheduled workflow is not started directly, but is triggered by a D2 job based on the future date you send with it.

Antal Bos

As far as i know there is a D2FS api available, but i'm not sure if these methods are described in it.

Mayur_shivs

Which API are you using or you have found for attaching workflow to the document in D2

Regards

Antal Bos

We use the 'D2FS 4.1 Javadoc', but it's indeed very minimal and almost unusable.

One of our developers used a tool called TCPMON.jar and placed it between the JMS and Application server. Then we started a workflow from D2 and picked up the message that was sent. With that message information we could build that message in Java again with the correct attribute-list.

Mayur_shivs

does you have the sequence of attributes which needs to pass to the launchWorkflowRequest , if you have that please let me know the sequence

Regards

Antal Bos

For starting a D2 workflow we came to this list:

attr.setName("list");
attr.setValue("config");

attr.setName("config");
attr.setValue(strWf);

attr.setName("workflow_label");
attr.setValue(strWf);

attr.setName("name");
attr.setValue(strWf);

attr.setName("labelNotification");
attr.setValue("");

attr.setName("notification");
attr.setValue("");

attr.setName("launch_date");
attr.setValue("");

attr.setName("launch_notification");
attr.setValue("");

attr.setName("end_of_workflow");
attr.setValue("");

attr.setName("list");
attr.setValue("workflow_label¬name¬labelNotification¬notification¬add_document_id¬launch_date¬launch_notification¬end_of_workflow");

Mayur_shivs

Thanks for help ,

but i am somewhat confused on first two and last two lines of the previous answer

attr.setName("list");

attr.setValue("config");

what should i pass in as "list" and "config" i have tried "d2_workflow_config" for attr.setValue("config"); but that not working

and in the last two lines

attr.setName("list");

attr.setValue("workflow_label¬name¬labelNotification¬notification¬add_document_id¬launch_date¬launch_notification¬end

what is "list" and whats the separator "workflow_label¬name¬l" ie : "¬" this one

This is the message we picked up with tcpmon.jar:

We rebuild this message in Java like this (Those 'Â¬' just come with the copy from tcpmon to eclipse):

//Create a new ValidDialogRequest
ValidDialogRequest request = new ValidDialogRequest();
request.setId(<<Object ID of document in Package>>);
request.setDialogName("D2WorkflowLaunchDialog");
request.setContext(context);

//Set all the attributes like in the tcp-message
attr = new Attribute();
attr.setName("config");
attr.setType(2);
attr.setValue(<<See the tcp-message>>);
request.getAttributes().add(attr);

...

//Send out the request
final ValidDialogResponse response = (ValidDialogResponse)new D2FSWebServiceSupport().getWebServiceTemplate().marshalSendAndReceive(request);

Mayur_shivs

Thanks for the help , I am not finding "D2FSWebServiceSupport" this class in any of the jar file , so which jar does have this class , I have 4 jars in my classpath

1) the jar build from D2FS wsdl

2) streambuffer.jar

3) D2FS4DCTM-LanguagePack_en_4.0.1_019.jar

4) D2FS-remote.jar

Regards

Antal Bos

That is a custom Class that extends from org.springframework.ws.client.core.support.WebServiceGatewaySupport

Hello

this is my code

ValidDialogRequest request = new ValidDialogRequest();

request.setId("090072e58000b14f");

request.setDialogName("D2WorkflowLaunchDialog");

request.setContext(context);

Attribute attr = new Attribute();

attr.setType(2);

attr.setName("list");

attr.setValue("");

then i have set the value and name of attributes according to my configuration

and in the end i am launching it through import com.emc.d2fs.schemas.models.ModelPort;

like this

request.getAttributes().add(attr);

port.validDialog(request);

i am getting this error

how to resolve this

It looks like it searches for a workflow without a name:

com.emc.common.dctm.exceptions.C6ObjectNotFoundByNameException: Workflow object

"" not found.

Did you set these attributes:

config = <name of the workflow in D2>

workflow_label = <label of the workflow in D2>

name = <name of the workflow in BPM/workflow manager>

Mayur_shivs

Yes i have set these

attr.setName("config");

attr.setValue("myWorkflow");

attr.setName("workflow_label");

attr.setValue("MyWorkflow");

attr.setName("name");

attr.setValue("Workflow 1");// 10 Jun 2013 17:35:35");

but when i am remote monitored TCP messages i am getting like this

|list

|config

|myWorkflow

|workflow_label

|name

|myWorkflow 11 Jun 2013 11:08:13

|reviewers

|mayur

|approvers

|labelNotification

||notification

|launch_date

|launch_notification

|false

|end_of_workflow

|workflow_label¬name¬reviewers¬approvers¬rewriters¬labelNotification¬notification¬add_document_id¬launch_date¬launch_notification¬end_of_workflow

|buttonId

|buttonOk

i am getting time stamp with name , so that time stamp is going to change every time , so does this error is from this thing

and if the value of any field is empty i am doing like this

attr.setName("launch_date");

attr.setValue(" ");

is this the right way

Regards

Antal Bos

This information is incorrect:
name = <name of the workflow in BPM/workflow manager>

The name can be a selve described name, so you are free to use your own name as far as i can see.

.The launch_date can be used to start the workflow on a later time with the D2 job 'D2JobWFLaunchScheduledWorkflows'

Antal Bos

I see you only do a request.getAttributes().add(attr); at the end?

You Attribute object is everytime overwritten in your code.

So the only item in your Attribute object should be buttonId = buttonOk.

Try it like this:

Attribute attr = new Attribute();

attr.setName("config");

attr.setType(2);

attr.setValue("myWorkflow");

request.getAttributes().add(attr);

attr = new Attribute();

attr.setName("workflow_label");

attr.setType(2);

attr.setValue("MyWorkflow");

request.getAttributes().add(attr);

attr = new Attribute();

attr.setName("reviewers");

attr.setType(2);

attr.setValue("mayur");

request.getAttributes().add(attr);

etc...

: Thanks very much Guru , Struggled a lot for this , tried lots of thing but it was eventually you who solved this big problem

You're welcome!

Hi Mayur,

How to get the classes for ModalPort from wsdl?

Regards,

Nitesh

Mayur_shivs

Hi Nitesh ,

Did you got the answer if not here is the procedure

Use the wsimport command (included with your JDK) to generate a set of java source

files for the stub libraries you will need to connect. Add the -keep option in order to

EMC Documentum D2 4.1 Architecture 10

preserve the generated java files after the command has finished running. Depending on

where you have deployed D2, the command will look something like:

wsimport -keep http://localhost:8080/D2/ws/d2fs.wsdl

Build the JAR file for generated classes and add it in your project

Regards

Shilpa_A123

Hi Mayur,

Could you please provide code for 'D2FSWebServiceSupport' mentioned in post? I'm struggling with this and not getting details. If you can provide pointers, it would be great.

Thanks,

Shilpa
