Make inbound calls.
Step 8 towards the goal:
Using optimized local adapters for inbound support
About this task
Depending on what you want to achieve and what kind of systems you are working with, choose the method you want to use to make calls with the native APIs.
Before you begin
Secure optimized local adapters for inbound support.
Procedure
Use the optimized local adapter native APIs to call a stateless session bean and connect from an external address space to
WebSphere
®
Application Server
.
In this method, you invoke an EJB application from an external native language program using the primitive APIs and retrieve the response. This method is designed for applications that want more flexibility and where the response area maximum length is not known prior to the call.
Use the optimized local adapter Invoke API to call a stateless session bean and connect from an external address space to
WebSphere
®
Application Server
.
In this method, you invoke an EJB application with the Invoke API from an external native language program and retrieve a response. This method is designed for exploiters that want a simplified path where the response area length is known prior to the call.
Use the optimized local adapter to call an EJB application from
WebSphere
®
Application Server
from an external address space in a client-initiated transaction
.
In this method, you begin a transaction in a client environment, and call an EJB application that is running on
WebSphere
®
Application Server
. The new transaction is propagated to the
WebSphere
®
Application Server
. This method is only supported when calling from a transaction-enable environment, like CICS
®
.
Use the optimized local adapter to call an EJB application from
WebSphere
®
Application Server
while ignoring the transaction context
.
In this method, you begin a transaction in a client environment, and call an EJB application that is deployed on
WebSphere
®
Application Server
, and ignore the transaction context. This method is only supported when calling from a transaction-enable environment, like CICS
®
.
