WSRP version 2.0 milestone 1 binary now available

The Open Portal WSRP Project has recently released the milestone 1 binary of WSRP version 2.0 implementation. The same is available for download here. Here is the link to the install and user guide for this milestone.
  1. Install Instructions
  2. User Guide
The WSRP version 2.0 milestone 1 release is the first release from the OpenPortal WSRP Project that implements the OASIS WSRP version 2.0 specification. The main intent of this release is to provide a base platform for developers to build optional and additional features that are defined in the WSRP version 2.0 specification and demonstrate to WSRP users the basic usecases of using both the versions.

Technically since all the major features of the WSRP version 2.0 specification are defined optional, we already have a WSRP version 2.0 implementation, by just porting the version 1.0 implementation to 2.0 schema's and claim version 2.0 compliance. However to have a meaningful version 2.0 implementation, the optional features are required to be implemented. The OpenPortal WSRP Project addresses/implements these optional features in the subsequent milestone. Please check the WSRP version 2.0 Project page for more details.

So what exactly is there in this release ?
  1. Provides a base v2 implementation by porting v1 implementation to v2 schema's.
  2. Provides both version 2.0 and version 1.0 WSRP Producer implementation.
  3. Supports sharing of resources like registration-handle/portlet-handle across v1 and v2 WSRP Producer services.
  4. Provides both version 1.0 and 2.0 implementation of Consumer.
  5. Provides the necessary administrative interface to create a v1 or v2 Consumer.
  6. Supports backward compatibility by supporting both v1 and v2 stacks.

Note : The code base uses OASIS WSRP public review 04 schema to demonstrate the above
