Configuring EJB bindings in SCA OASIS applications

You can configure Enterprise JavaBeans (EJB) service and reference bindings for use in SCA OASIS applications.

About this task

[AIX Solaris HP-UX Linux Windows][z/OS] New feature New feature:
The SCA stateless session bean binding is a protocol binding that you can use to integrate SCA with EJB-based services. The product provides OASIS support for both EJB 3.x and 2.x bindings for services and references.newfeat

Procedure

Results

You have configured an EJB service or reference binding for an SCA OASIS application.

Use of the bindings has the following limitations:
  • A local EJB invocation from a Java EE application to an SCA service with an EJB 2.x or EJB 3.x binding is not supported.
  • A Java EE application running on a non-WebSphere application server, on "bare" Java Standard Edition (SE), or on a WebSphere application server previous to Version 7.0 without the Feature Pack for EJB 3.0 cannot invoke the SCA EJB 3.x service binding.
  • The product does not support an SCA composite that has both EJB 2.x and EJB 3.x services in different components but implements the same interface.

What to do next

Ensure that your components do not use an SCA OASIS implementation that the product does not support.

Table 1. Unsupported sections of SCA OASIS specifications. The product does not support these sections of the SCA EJB Session Bean Binding specification.
Section Not supported in SCA OASIS implementation
2 Session Bean Binding Schema binding.ejb/@uri for SCA service binding
  • The SCA stateless EJB implementation automatically generates a unique URI based on the component name, service name, and service interface. The URI is used as the EJB service endpoint.

    See step 1 in the "Configure EJB service bindings and invoke them in caller applications" procedure.

  • The product supports the cobra url format:
    corbaname:iiop:host:port/NameServiceServerRoot#jndi_name
ejb-link-name
  • The product does not support ejb-link-name in the SCA OASIS implementation.
