WebLogic Console and BPM Worklist. Authentication using OpenLDAP by Maarten Smeets


clip_image002In this blog I will illustrate how you can configure Weblogic Server to use OpenLDAP as authentication provider and to allow OpenLDAP users to login to the Oracle BPM Worklist application. In a previous blog I have already shown how to do Weblogic Authentication with ApacheDS (LDAP and Weblogic; Using ApacheDS as authentication provider for Weblogic). In this blog I will use OpenLDAP to also do BPM Worklist authentication.


Why use OpenLDAP?

Oracle Platform Security Services (OPSS) supports the use of several authentication providers. See: http://docs.oracle.com/cd/E23943_01/core.1111/e10043/devuserole.htm#JISEC2474. OpenLDAP is the only open source provider available in this list.

  • Microsoft Active Directory
  • Novell eDirectory
  • Oracle Directory Server Enterprise Edition
  • Oracle Internet Directory
  • Oracle Virtual Directory
  • OpenLDAP
  • Oracle WebLogic Server Embedded LDAP Directory
  • Microsoft ADAM
  • IBM Tivoli

When you can use a certain provider for Weblogic authentication, this does not automatically mean you also use this user in Fusion Middleware applications which use JPS such as the BPM Worklist application. Possible authentication providers in Weblogic Server cover a wider range of servers and mechanisms than can be used in JPS out of the box.

What causes this limitation? Well, most Fusion Middleware Applications (all as far as I’ve seen) can only look at the first LDAP provider for authentication. This is usually the default authenticator (Weblogic Embedded LDAP server). When I add another LDAP authenticator, it will be ignored. The solution is straightforward; use a single LDAP. Of course if you don’t want that, you can also virtualize several LDAPs and offer them as a single LDAP for the application to talk to. The most common solutions for this are; Oracle Virtual Directory (OVD, http://docs.oracle.com/cd/E12839_01/oid.1111/e10036/basics_10_ovd_what.htm) and LibOVD. Oracle Virtual Directory is a separate product. LibOVD is provided with Weblogic Server but does not have its own web-interface and is limited in functionality (and configuration is more troublesome in my opinion). When (for example for ApacheDS) you specify the generic LDAPAuthenticator and not a specific one such as for OpenLDAP, you need to specify an idstore.type in the jps-config.xml in DOMAINDIR\config\fmwconfig. This idstore.type is limited to the list below: Read the complete article here.

Creating Custom BPM Work List for Human Tasks based in ADF by Mark Peterson

clip_image002If you ever need a custom work list and need to open the human task from this list, then this blog can help you. All you really need to do is find the list of tasks and create the URL that opens the task from the custom work list. This is not as straightforward as it seems since the URL contains some dynamic fields that you will need to derive from information about the tasks.

The need for a custom work list usually involves some sort of relationship between instances in a process, or between tasks in different processes such that the OOTB functionality of the BPM workspace is not sufficient. The user wants to see a logical grouping of tasks or between parent and child tasks. These tasks should be shown grouped together. These tasks can be shown in a table or tree format and each task should have a link to click on to open the task directly from the form. This is an example of such a list and grouping.

Use Cases

The relationships between tasks may consist of simple parent/child relationships. The above table was used to implement a custom ACM UI where each of these tasks (children) are activities for a given case (parent). Here a work request (case) with several child tasks, or activities are listed along with the status, description due date, started date and assignee. Notice the links to open the task or reassign the task.

Another example is when a tasks is related to another other (like siblings) by customer or account ID. In all of these examples, the user wants a convenient way to jump directly to the related task, without closing the current task or form, going to the work space, finding and opening the task from the work space. Here are some example users stories this post can help you implement.

  1. As an agent, I want to open a task associated with a leg of a trip from the trip overview page, so I don't have to search and find the task in the workspace, when I'm working on the trip.
  2. As a user, I want to be able to see all tasks associated with a work requests and be able to open a task to work on it without having to find the task in the workspace when I'm working on the work request.
  3. As a underwriter, I want to be able to see all related line items on a insurance policy and be able to jump to any of these line items from any other line item in the policy without need to find and open the line item from the workspace.
ADF URL Parameters

The URL pattern you need to construct is as follows:

http://hostname:port/faces/adf.task-flow?bpmWorklistTaskId=<TaskId>&adf....

The following parameters needs to be derived and appended to this URL using the amphersand "&" as a delimiter between parameters and an equal sign "=" between the parameter and value. The parameter value pair a listed in the following table. Read the complete article here.

Integrating Custom BPM Worklist into WebCenter Portal (Same Domain for BPM and WebCenter) by Red Samurai

http://2.bp.blogspot.com/-5jAvXzUNY24/UlkqQRvJaJI/AAAAAAAAKYU/xJ4yqWTWiCg/s320/13.pngI would like to share sample application configured to run custom BPM Worklist and steps describing how to configure and access it from the WebCenter Portal. This post will be based on two other posts from my blog, I would recommend to go through them first. The one where is described how to extend WebCenter Portal 11.1.1.8 - Extending WebCenter Portal 11.1.1.8 Made Easy. Other one about deploying custom ADF shared libraries - Deploying ADF Applications as Shared Libraries on WLS. For this post, I assume BPM and WebCenter environment is running on the same domain. There is one more - custom BPM Worklist access implementation through BPM Java API - ADF 11g PS5 Application with Customized BPM Worklist Task Flow (MDS Seeded Customization).
BPM and WebCenter Portal runs on the same domain - each of different WebLogic Managed Server. With such configuration, setup is quite straightforward, comparing to having separate domains: Read the complete article here.
