Prabath,
Are you familiar with JSR 196?
Have you considered encapsulating your openid consumer code in a JSR 196 Server Auth Module (i.e, SAM)?
When a SAM is integrated in the Glassfish servlet container, it is applied by the container's constraint processing machinery on behalf of applications for which it is configured, and without requiring recompilation or redeployment of the applications.
At present the 196 SPI is supported by Glassfish, and there is work going on to provide support for the SPI in other containers including JBOSS, Tomcat, and Geronimo. The SPI is expected to be a required component of EE 6.
