webMethods is pleased to introduce the webMethods Enterprise JavaBeans Adapter 6.0 (EJB Adapter) for integrating with EJB-based business applications. The webMethods EJB Adapter provides seamless and real-time communication with application servers, enabling you to exchange data between a webMethods Integration Server and Enterprise JavaBeans on a J2EE application server. The EJB Adapter provides companies with a complete set of tools to rapidly integrate their EJBs with the webMethods Integration Server.
Using functionality provided by the adapter, the Integration Server can identify the EJBs deployed on the application server, create a remote instance of an EJB, and then invoke a selected method on the remote bean instance. For example, you can use the EJB Adapter to create services that webMethods Integration Server clients use to create and update account information for a database connected to an application server that provides EJB capabilities.
The EJB Adapter enables you to establish and manage connections to your EJB servers. Connections, connection pools, and sessions are fully managed by the adapter. Through these connections, you can create and run your EJB integrations.
The EJB Adapter provides service templates for interactions with EJBs. This makes it easy to develop adapter services to interact with EJBs. Service templates represent specific operations.
The EJB Adapter provides the ability to generate adapter services that implement the following operations:
| Adapter Service Template | Description |
| CreateEJB | Creates one or more instances of a single remote EJB class and returns the EJB handles to the caller. |
| InvokeEJB | Invokes a single method on an existing EJB. |
| CreateInvokeEJB | Creates one or more instances of a single EJB class and invokes a single method on those instances. |
The open framework of the webMethods Integration Server enables bi-directional interaction between the EJB server and the webMethods Integration Server. With the proper client classes and input parameters, EJBs can initiate a connection to the webMethods Integration Server. Once the connection is established, any service on the Integration Server can be invoked by providing its folder and service name. Provided with the EJB Adapter is source code for a sample EJB application that illustrates how to implement code that invokes services on a webMethods Integration Server.
The webMethods EJB Adapter supports the following J2EE Enterprise JavaBean servers:
Note: For the most up to date information about the software and operating systems that the adapter supports, see the webMethods Enterprise JavaBeans Adapter Installation Guide Version 6.0 that is posted on the webMethods Advantage Product Download Site and the Advantage Bookshelf (http://advantage.webmethods.com/Bookshelf).
