WSRP version 2.0 implementation on OpenPortal WSRP project

The implementation of the WSRP version 2.0 is in full swing in the OpenPortal WSRP Project community. Here is the link to the project wiki page that tracks this project.
Apart form this the following documents are also available for review
  1. WSRP v2 FSD
  2. WSRP Consumer Admin Usecases
  3. Eventing Usecases
  4. Architecture changes for WSRP v2
  5. Project Plan
If you have comments or questions, pls join the project and post your queries or comments. Stay tuned for the milestone 1 drop which is expected in the next few weeks also for more features in the future drops.

Uninstalling OpenPortal WSRP and PortletContainer

Here is how you uninstall OpenPortal WSRP and OpenPortal PortletContainer projects after successful installation without having to uninstall the whole glassfish application server. Recently I came across this issue since someone asked about it and this information was not available or documented anywhere.


Uninstall OpenPortal WSRP :

Upon successful install of OpenPortal WSRP, The installer would have created a 'wsrp' directory as <glassfish_install>/domains/domain1/wsrp. There is a setup.xml under this directory, invoking the 'uninstall-wsrp' ant target does the job. Here is the example

# ant -f setup.xml uninstall-wsrp.

Make sure you restart the glassfish application server after this.


Uninstall OpenPortal PortletContainer :

Similar instructions apply the OpenPortal PortletContainer uninstall procedure. Upon successful install of OpenPortal PortletContainer, the installer would have created a 'portlet-container' directory as <glassfish_install>/domains/domain1/portlet-container. There is a setup.xml under this directory, invoking the 'uninstall-pc' ant target does the job. Here is the example


# ant -f setup.xml uninstall-pc.

 Make sure you restart the glassfish application server after this.

OpenPortal WSRP Project consumed by OpenPortal


The OpenPortal WSRP project is consumed or integrated into the OpenPortal project, Here is a note on some of the integration that was done.

Java Persistence API based (JPA) based datastore :

Added a new datastore for storing WSRP Producer and WSRP Consumer related configurations The file based datastore that OpenPortal WSRP Project is unacceptable as the configurations stored in file would be local to specific portal server node. The JPA based WSRP datastore implementation by default uses derby as backend to store all the WSRP Producer and Consumer related configuration information.


Note : The source code for this resides in the OpenPortal WSRP Project as this can be used outside of the OpenPortal. Watch this space for more details on how to use it in OpenPortal WSRP Project.

User Management:

The OpenPortal project customizes the user datastore of the OpenPortal WSRP Project, its provides user store where WSRP users are created and managed on to the LDAP server that is used by the OpenPortal installation. OpenPortal project creates creates people container under organizational units for each consumer registration The people container is used for creating phantom users that are specific to a consumer registration.


Note : Pls see the other entries on WSRP User Identity Propagation to know more about phantom users and identity propagation techniques

Role Management :

OpenPortal uses roles in LDAP/Access Manager to store explicitly cloned portlets. Explicit clones are portlet clones that are created by consumers that needs to be shared by all the users. Hence the cloned portlet is stored on to the role and all users under that consumer registration are assigned to this role, which makes the portlet clone available to all the users under this consumer registration.


Here is a simple representation, the WSRP Producer and WSRP Consumer stores configuration onto a database. The WSRP Producer uses the AM /LDAP  server to create users and roles for the above mentioned functionalities.


Single SignOn Token(SSOToken) Identity Propagation:

OpenPortal uses AccessManager(AM) to authenticate users, authenticated users are represented by a Single SignOn Token(SSOToken) in AM. Since SSOToken is used only in OpenPortal, the SSO identity propagation is added as an extension by the OpenPortal Project to WSRP Project.


When this option is selected the SSOToken associated with the user is propagated as an UserContext extension by the WSRP Consumer to the WSRP Producer which represents a user. 


Note : This identity propagation mechanism assumes that both Consumer and Producer Portal are OpenPortal installations. Pls see this entry for more details

WSRP Mbeans :

The OpenPortal WSRP Project Mbeans are consumed by the OpenPortal and integrated into the OpenPortal Portal Administration Server (PAS) module, the WSRP Mbeans are deployed on to the Common Agent Container for APG and Orion/Common Agent Container (CACAO/CAC) management server. The OpenPortal administrative console (psconsole) provides a user interface for WSRP administrative purposes using the above Mbeans.


Note: Pls see the architecture here and the intent of this design.

WebService Single Sign On (WSSSO) Portlet :

The OpenPortal project provides a portlet/user-interface that allows users to add/provide Single SignOn information in the form of a username and password. This portlet stores the user credentials that is used by the WSRP Consumer to create a OASIS Username Token profile and propagate the user identity to the WSRP Producer portal.


Note : The WSSSO Portlet uses the SSOAdapter infrastructure to store user credentails, Pls see here for more information on SSO Adapter.

WSRP 2.0 - A Sneak Peek

Here is the list of features that WSRP 2.0  addresses or adds over WSRPv1 specification. We'll try to contrast and compare with the JSR286 specification in some places and see how these two specifications compliment each other. Here is the list of new stuffs that WSRP v2 brings to the table.
