BPM getTaskDisplayURL workflow version issue

Jack Issac

Hi,

I'm using JDev 11.1.1.9

I prepared custom worklist for webcenter portal and I'm getting tasks of user with bpm api.

For a bpm application, I deployed 2 different version to soa server. They have different URI for their UI project, like following URI:

/workflow/v0.2b/PersonelBPM_ADF/faces/adf.task-flow?_id=PersonelHT_TaskFlow&_document=WEB-INF/PersonelHT_TaskFlow.xml

/workflow/v0.1b/PersonelBPM_ADF/faces/adf.task-flow?_id=PersonelHT_TaskFlow&_document=WEB-INF/PersonelHT_TaskFlow.xml

Also I'm showing task to user in a inline popup using modal-dialog-task-flow. For show task to user, I'm getting display url following code,

                    Map parameters = new HashMap();

                    parameters.put(Constants.BPM_WORKLIST_TASK_ID,

                                   task.getSystemAttributes().getTaskId());

                    parameters.put(Constants.BPM_WORKLIST_CONTEXT,

                                   getWfCtx().getToken());

                   parameters.put(Constants. BPM_PARENT_URL,

                                   ProjectUtils.getSOAUrl() + "/worklist");

                    //--

                    //---------------------------------

                    String taskURL =

                        WorklistUtil.getTaskDisplayURL(getWfSvcClient(),

                                                       getWfCtx(), task, null,

                                                       "worklist", parameters);

This code is giving to me task url; but it's not giving right task url for different version of applications.

Example, I started the process separately. 1 process in 0.1 version, 1 process in 0.2 version.

When I get tasks url, they are same workflow URI for all process in this application; but I'm expecting like following urls:

For 0.1b version:

http://<hostname>:<port>/workflow/v0.1b/PersonelBPM_ADF/faces/adf.task-flow?_id=PersonelHT_TaskFlow&_document=WEB-INF/PersonelHT_TaskFlow.xml/...............................

For 0.2b version:

http://<hostname>:<port>/workflow/v0.2b/PersonelBPM_ADF/faces/adf.task-flow?_id=PersonelHT_TaskFlow&_document=WEB-INF/PersonelHT_TaskFlow.xml/...............................

Also I checked URI of soa composite in Enterprise Manager, they have different URI.

Thanks,

Jack.

Hi Jack,

I had a same problem. I solved like this,

    String taskDefID = task.getSystemAttributes().getTaskDefinitionId();

    String getBPMProjectNameFromTaskDefID(String taskDefID) {

        try {

            //Example Def ID

            //soa_partition/ProjectName!CompositeVersion/UI_ProjectName

            //default/BPMProject!0.1/BPMProjectUI

              

            String projectNameWithVersion =

                taskDefID.substring(taskDefID.indexOf("/") + 1,

                                    taskDefID.lastIndexOf("/"));

            String version =

                projectNameWithVersion.substring(0, projectNameWithVersion.indexOf("!"));

            return version;

        } catch (Exception ex) {

            ex.printStackTrace();

            return "";

        }

    }

    private String getTaskURIFromTaskDisplayURL(String taskDisplayURL) {

        try {

            String workflowSubString =

                taskDisplayURL.substring(taskDisplayURL.lastIndexOf("workflow"));

            String[] splittedworkflowSubString =

                workflowSubString.split("/", 3);

            String taskURI = splittedworkflowSubString[2];

            System.out.println("Task URI : " + taskURI);

            return taskURI;

        } catch (Exception ex) {

            ex.printStackTrace();

            return "";

        }

    }

    private String reGenerateTaskDisplayURLByCompositeVersion(String taskURI,

                                                              String compositeVersion) {

        try {

            String workflowURL = ProjectUtils.getWorkflowUrl();

            String reGeneratedWorkflowURLWithCompositeVersion =

                workflowURL + "/" + "v" + compositeVersion + "/" + taskURI;

            return reGeneratedWorkflowURLWithCompositeVersion;

        } catch (Exception ex) {

            ex.printStackTrace();

            return "";

        }

    }

I solved like this; because task.getSca().getCompositeVersion(), retuned null everytime.

But for use these functions,

All your bpm project URI have to like /workflow/v.1.1/.....

Thanks.

Hi,

Is there any advice?

Is this a bug or my mistake?

Doesn't anybody knows?

Thanks,

Hi @BSRT

Thanks for your answer.

Yes, I did all uri as you say and I used your functions.

it's working fine now.

Thanks much.

Jack.
