Building Custom Worklist application in 11g using wlfullclient.jar

Hi,
Can anybody mention me the detailed steps to be followed to build a custom Worklist application.
I have created a Web application jdev 11g
I placed the following url to create
http://download.oracle.com/docs/cd/E1552301/integration.1111/e10224/bp_worklistcust.htm_+
placed the following jars in classpath
Wsclient_extended.jar
Bpm-services.jar
Bpm-infra.jar
Wlfullclient.jar
xmlparserv2.jar
xml.jar
I did not find this bpm-services-client.jar* anywhere in the SOA stack. I am missing this??
and also place wf_client_config.xml under src folder the content is as below
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<workflowServicesClientConfiguration xmlns="http://xmlns.oracle.com/bpel/services/client">
<server name ="default" default="true" >
<localClient>
<participateInClientTransaction>false</participateInClientTransaction>
</localClient>
<remoteClient>
<serverURL>t3://localhost:7001</serverURL>
<userName>weblogic</userName>
<password>weblogic123</password>
<initialContextFactory>weblogic.jndi.WLInitialContextFactory
</initialContextFactory>
<participateInClientTransaction>false</participateInClientTransaction>
</remoteClient>
<soapClient>
<rootEndPointURL>http://localhost:7001</rootEndPointURL>
<identityPropagation mode="dynamic" type="saml">
<policy-references>
<policy-reference enabled="true" category="security"
uri="oracle/wss10_saml_token_client_policy"/>
</policy-references>
</identityPropagation>
</soapClient>
</server>
</workflowServicesClientConfiguration>
And I have placed web.xml and weblogic.xml under WEB-INF folder.
I do not have any compile time error.
But when I am trying to deploy the application I am getting the following error.
If i remove the wlfullclient.jar I am not getting this error as it is trying to load something while deployment.
Please can anybody tell me what exactly I am missing.

Problems with building custom worklist application

I'am trying to build a custom worklist application using this: http://download.oracle.com/docs/cd/E15523_01/integration.1111/e10224/bp_worklistcust.htm
Here is the code I've built so far (it si quite simple but, for now, I'm just trying to get hold of the concepts involved):
public class Test {
public static void main(String[] args) {
IWorkflowServiceClient wfsc = WorkflowServiceClientFactory.getWorkflowServiceClient(WorkflowServiceClientFactory.REMOTE_CLIENT);
ITaskQueryService queryService = wfsc.getTaskQueryService();
IWorkflowContext context;
try {
context = queryService.authenticate("jstein", "welcome1".toCharArray(), null);
} catch (WorkflowException e) {
e.printStackTrace();
When I run this I get the following exception trace:

I would appreciate any help. I'm really stuck with this..
Thanks! :)

I've finally found a solution to this problem. The problem was that I was trying to connect to a workflow api on the *7001* port but that wasn't the correct port. The correct port is *8001*.
I came to this conclusion quite accidental (or out of desperation if you like).
What I don't understand is that in every single official Oracle document about workflow and worklist the port they were targeting was *7001*. I have to emphasize that I installed SOA 11g suite with all default settings.
Problem solved, moving on.

Deploying the Custom Worklist Application When run ant script Fail

Hi
I have tried to deploy worklist application on Oracle SOA Suite to custom it and I have follow the BPEL Process Manager Developer's Guide (10.1.3.1.0) in chapter 16 topic 16.5.1.5. Deploy the Custom Worklist Application but whenI tried to run ant script to deploy custom worklist application, the error has occur "Unexpected element "echo" ". I access to build.xml file to comment element echo out and run ant again but the new error has occured "The <fail> task doesn't support the nested "condition" element." . How should I do for deploy custom application ?
I use ant -version to check ant version and message has show "Apache Ant version 1.5.2-23 compiled on November 12 2003"
Please help me!

Hi ,
I am facing the same issue. Were u able to solve this ?

Custom worklist application integration with BPEL cluster

Hi all,
I've setup a BPEL cluster using the Enterprise installation guide for 10.1.3.3.0. Currently we have a custom worklist application which is works when deployed on an installation SOA suite (10.1.3.1.0). The integration of claiming or setting an outcome works fine. We use the remote EJB to integrate with the workflow services.
However when testing the application on a cluster, we are getting the following log message in the log file for the custom application:
Questions:
1) What should be the value of the host name in the server URL since in a cluster a remote HTTP server. The HTTP server uses a virtual URL via the loadbalancer.
2) What should be the port number? Should it be the opmn request port from the $ORACLE_HOME/opmn/conf/opmn.xml
Anything else that i'm missing, please let me knoe.
Thanks in advance.

Some more information:

2) I've tried using both the machine name and the http server name in the server url.
3) Snapshot of the wf_client_config.xml:

Building a custom worklist client in 11g R1 fails to authenticate [Solved]

Release: 11gR1
Hi,
We're trying to build a custom worklist client using the APIs exposed by the workflow service described here:
http://download.oracle.com/docs/cd/E12839_01/integration.1111/e10224/bp_worklistcust.htm#BHAHBHID
I created an ADF/webcenter application.
Created a page and added ADF security to the page which in turn authenticates via OID - this works.
However when I try to use the workflow API to retrieve the workflow context I receive this exception:
========= get tasks =========

admin pw : weblogic1
realm : myrealm

Further Notes:
The out-of-the-box worklistapp included with BPEL authenticates correctly through the same OID instance.
The above was when I used REMOTE_CLIENT, I get a similar error when I use SOAP_CLIENT.
Any help is greatly appreciated.

Hi Guys,
Thank you for taking the time to answer my questions, from your replies I gathered that I was barking up the wrong tree.
I'll comment on my solution below for the curious.
thx
Bud
I left my wf_client_config.xml file as is. (shown in the original comment above - I have this file in the ViewController project's src directory - not the global src directory)
I reverted my workflow-identity-config.xml file to its original state (ie removed the multiple configurations and defaulted to the jazn.com realm):
<?xml version = '1.0' encoding = 'UTF-8'?>
<ISConfiguration xmlns="http://www.oracle.com/pcbpel/identityservice/isconfig" >
<configurations>
<configuration realmName="jazn.com">
<provider providerType="JPS" name="JpsProvider" service="Identity">
<property name="jpsContextName" value="default" />
</provider>
</configuration>
</configurations>
<property name="caseSensitive" value="false"/>
</ISConfiguration>
It seemed to me that the worklist client service (API) always uses jazn.com as the realm, even though I added users to myrealm (weblogic's default realm) via oid.
When I browse for users in a HumanTask.task file in JDeveloper for instance the users I had added to myrealm show up in the jazn.com realm - which is okay since they're all in there.
Since this is a client and we don't really know the password of a user logging in I used the authenticateOnBehalfOf() method to get the IWorkflowContext of the user after getting the IWorkflowContext of an Administrator.
In order to get an administrator IWorkflowContext you need to authenticate against a user who is in the 'Administrators' group.
The code I used is below:
public class worklistService {
String adminUser = "harry";
String adminPassword = "welcome1";
String realm = "jazn.com";
public List getTasks() throws WorkflowException, StaleObjectException {
String user = ADFContext.getCurrent().getSecurityContext().getUserName();
try {
IWorkflowServiceClient iWorkflowServiceClient = WorkflowServiceClientFactory.getWorkflowServiceClient(WorkflowServiceClientFactory.REMOTE_CLIENT);
ITaskQueryService iTaskQueryService = iWorkflowServiceClient.getTaskQueryService();
System.out.println("admin user : " + adminUser);
System.out.println("admin pw : " + adminPassword);
System.out.println("realm : " + realm);
System.out.println("user : " + user);
IWorkflowContext directUserContext = iTaskQueryService.authenticate("ben", adminPassword.toCharArray(), realm);
System.out.println("------ directUserContext : " + directUserContext);
IWorkflowContext adminContext = iTaskQueryService.authenticate(adminUser, adminPassword.toCharArray(), realm);
System.out.println("------ adminContext : " + adminContext);
IWorkflowContext userContext = iTaskQueryService.authenticateOnBehalfOf(adminContext,user);
System.out.println("------ userContext : " + userContext);
Hope this helps someone else ...

BPEL transaction in custom worklist application

Hi,
How can we be sure about transaction while performing actions within worklist client?
Such an example, we developed an application by using oracle soa suite worklist api's.
Beside task updating,payload adjustion we need to do some other jobs including business logic in our java client application.
In such cases, if there is an exception at java code, it doesnt commit to database but bpel integration code performs... Is there any way which you can control all this functions calling within one transaction? I want to rollback all if you come up with an exception.
I found an xml attribute which you need to configure in wf client config.xml, we use RMI for performing actions...
participateInClientTransaction true
How does it work?
Thanks for help,
Regards...

Hi,
Every release of soa suite may have an updated version of the worklist application. So if you customize the application and upgrade your soa suite installation there may be ar risk you get into problems. However, most of the time the updated version solves existing bug and no more than that. An other issue is that if you are using the bpel libraries to connect to a bpel server the client always needs to be of the same version as the server. What you should do is:
- get the new 10.1.3.3 version of the libraries or install JDeveloper 10.1.3.3
- update your orabpel.properties file and make sure the bpel home is pointing to the new version
- update/verify the build.xml that it is pointing to the new libraries
- rebuild/compile your customized worklist app against the new libraries
- redeploy the new worklist application to the 10.1.3.3 server
Kind Regards,
Andre

Translating worklist application - jdev 11g

Hi
I need to translate the worklist application into Faroese. I have tried to find information on how to do this. I found the WorklistResourceBundle.class but since this is compiled it's prett hard do.
Does anyone have some information on how I can translate the worklist app?
Is the source available somewhere for the worklist app?

Upgrading a customized bpel worklist application after patch update

Hi,
We have a customized worklist application running developed on SOA 10.1.3.1. Now that we are migrating to version 10.1.3.3. I have 2 related queries:
1. Is there any documentation on whatsnew in the worklist application provided by oracle as part of SOA suite 10.1.3.3. (When doing a file compare on the code, I find quite a few changes but I would like to know if there is a whatsnew feature list by oracle)
2. I would also like to know the best practices to migrate the customized worklist application to take advantage of the new features if any of the worklist application provided with SOA suite 10.1.3.3
Help on this is really appreciated.
Edited by: user10546490 on Jan 21, 2009 4:21 AM

Hi,
The worklist application is customizable but you are running into the biggest problem when you customize it. There is no predefined way to migrate your worklist application to the new version. If you only made changes to the user interface the best way to upgrade is to apply the changes you made to the 10.1.3.1 version also to the new 10.1.3.3 version (by the way i would certainly upgrade to 10.1.3.4 instead of 10.1.3.3 since you plan on upgrading anyway). This problem is exactly the reason we decided to build our own worklist application based on the api's that are also being used by Oracle's version of the worklist application. In most cases (until now) the api definitions are not that different. If you also made lots of changes to the application jsp's and code you have to merge them with the new version which will be a lot of work but i am afraid there is no other solution.
Kind Regards,

Please help if u have come acrross some error like this ..............

Hi,
I'm facing the same issue with SOA Suite 11.1.1.3 with weblogic 10.3.3.0.
I get the following exception:
Error occurred while updating task outcome. java.rmi.UnmarshalException: cannot unmarshaling return; nested exception is:
java.io.InvalidClassException: oracle.bpel.services.workflow.task.model.CustomTaskTypeImpl; local class incompatible: stream classdesc serialVersionUID = -5471687046445499096, local class serialVersionUID = -1564179312380198686
this was working fine with SOA Suite 11.1.1.1.
Please let me know if you guys have found the solution.
Thanks,
Makrand

Question about worklist applications

Hi
i tried to do the example listed in the Oracle BPEL developers guide ( "Building a Worklist Application Using the Worklist Service APIs" ) and when it comes to these
step : "Task task = (Task) tasks.get(i);" I get confused because I don't know if this Task is really a oracle.tip.pc.services.hw.task.tasktype.impl.Task.
Also, I printed the class name
Object obj= tasks.get(i);
System.out.println("Class name " + obj.getClass().getName());
and I got that the value returned was a oracle.tip.pc.services.hw.worklist.WorklistTask
am I wrong?
Thanks Nicolas Fonnegra M

Hi Nicolas
It's important to note that there is a difference between the local Worklist Service APIs and the Remote Worklist Service APIs.
The local API is based around oracle.tip.pc.api.worklist.IWorklistService and its implementation oracle.tip.pc.services.hw.worklist.WorklistService.
The remote API is based around oracle.tip.pc.services.hw.worklist.RemoteWorklistServiceClient.
The remote API provides only a sub-set of the functionality offered by the local API. It is recommended that you use the local API, unless you have to host your worklist application remotely from the workflow service.
The local worklist APIs use the class oracle.tip.pc.services.hw.worklist.WorklistTask to represent tasks, which provides more methods than the class oracle.tip.pc.services.hw.task.tasktype.impl.Task used by the remote APIs.
I suspect that you are using the local worklist API, in which case you should be casting to WorklistTask, not Task.
Hope this helps

BPM Custom Worklist Implementation

Hi everyone,
I am working on BPM custom worklist application. I followed the steps to create a sample page with using TaskList task flow as explained in [BPM User's Guide|http://docs.oracle.com/cd/E23943_01/user.1111/e15175/bpmug_ws_taskflows.htm#BACFBHAE]. But when I browse to the sample page that contains TaskList task flow, it just renendered a blank page and the below exception trace is thrown on SOA console. I guess it's coming from security related issue. Does anyone know what the cause of the problem is? Thanks in advance.

Web logic and SOA server are up and running.
I guess there has to be at least some config file but in the link I gave at the beginning I can't find any explanation how to write it.
Is there any better tutorial or explanation?
Please help :)

Difference between BPM Worklist Application & BPM WorkSpace

Hi
I'm a newbie to Oracle BPM.
I want to understand the difference between
Oracle BPM Worklist APplication (that we use for Human Tasks in SOA : host:port/integration/worklistapp)
and
Oracle Business Process Workspace (host:port/bpm/workspace)
I've done a sample BPM process to which the initiator is jcooper.
When I deployed the app, I could find the task in Workspace but not in WorklistApp. Why is it?
I know that one is specifically intended for BPM, but why can't we see the task for jcooper in WorklistApp?
Also, Can you extend your answer to explain Process Composer too(in this context )?
P.S. I could not find a post that covers the diff b/w the three at a high level.
Regards
RaviKiran

How to implement singleton service if i m using only jar and war component

hello,
in my application i m using only jar and war component .
as i m not using EAR for deployment so i dont have weblogic-application.xml file.
so in this case how i implement weblogic singleton service .and how to call active method

From the documentation:
After you have created a singleton service class using the SingletonService interface, you must define it as a singleton service within WebLogic Server. This singleton service object contains the following information:
The path to the class to load as the singleton service.
The preferred server and other candidate servers for the singleton service.
The following excerpt from the cluster element of config.xml shows how a singleton service is defined:
<singleton-service>
<name>SingletonTestServiceName</name>
<user-preferred-server>myManaged1</user-preferred-server>
<class-name>mycompany.myprogram.subpackage.SingletonTestServiceImpl</class-name>
<cluster>myCluster</cluster>
</singleton-service>
Note that the config.xml is located in the <domain-home>/config directory
