Adding or Editing a Java method
You can add a Java™ method for each function or service you want to access from the
enterprise information system. Additional methods can be added later
in the Java source editor from
the Enterprise Explorer view or through the Snippets view.
Procedure
- If you click Next on the J2C Java Bean Output Properties page
of the J2C Bean wizard, you can add a Java method now on theAdd method to J2C Java bean page. To add methods without the wizard: Important: The Add J2C Java Bean Method snippet does not automatically copy the J2C bean interface to the client EJB project until the J2C Deployment wizard is run. If the J2C deployment wizard has already been run or you need the new method to be reflected in the client project interface file immediately (if you are adding to a faces JSP web page, for example), copy the file manually to the client project.
- To add a Java method in the Enterprise Explorer view, expand your project and expand Java Resources > src > <implementation Java class>. Right click the class and select Source > Add/Edit J2C Java bean method.
- To add a Java method from the Snippets view, expand your project and expand Java Resources > src > <implementation Java class>. Double click this file to open it in the Java Editor. The Snippets view is found in the top right pane in the Web perspective, or in the bottom left pane of the Java EE perspective. Click J2C in the Snippets view, and right click, and select Add method to J2C Java bean, and select Insert. The New Java Method page appears.
- To add a Java method from the menu in the Java Editor, right click in the source view and select Source > Add/Edit J2C Java bean method.
- On the New Java Method page, click Add.
- In the Name field, type in a meaningful name (getCustomer, for example).
- Next, you specify the input and output data types for your Java method.
- Input type: For the input type, you can choose to browse for an existing data type, or click new to launch the CICS/IMS Data Binding wizard.
- Use input type for output: If your output data type is the same as your input type, you can select Use the input for output.
- Output type: If your output data type is different from your input type, you can choose to browse for an existing data type, or click new to launch the CICS/IMS Data Binding wizard.
- Click Next.
- Setting InteractionSpec properties
Once you have added a Java method or methods, you need to specify the InteractionSpec properties for each EIS transaction. - Exposing ConnectionSpec for input and exposing InteractionSpec and properties for input and output
You can expose the properties of InteractionSpec and ConnectionSpec for input as data so that your Java application can set the property values. For example, you can expose the execution timeout property of ECIInteractionSpec to provide a timeout value based on user input. - Example of manually exposing interactionSpec: CICS Taderc99 sample
You can expose the properties of InteractionSpec and ConnectionSpec for output so that your Java application can get the property values after the transaction has been executed. - Example of manually exposing interactionSpec and IMSConnectionSpec as input data: IMS phone book sample
You can expose the properties of IMSInteractionSpec and IMSConnectionSpec for input as data so that your Java application can set or get the property values. For example, can expose the user name and password properties of IMSConnectionSpec if your Java application is using component-managed EIS sign-on. Or, you can expose the client ID property of IMSConnectionSpec if your Java application is executing an interaction on a dedicated persistent socket connection. - Example of manually exposing interactionSpec as output data: IMS phone book sample
You can expose IMSInteractionSpec properties for output. Currently, the only output properties that can be exposed are asyncOutputAvailable, convEnded, and mapName. To expose these properties of IMSInteractionSpec for output, you must create an output class and modify the interface and implementation files of your J2C bean before using it in an application. - Creating an MFS-based conversational application
The IMS™ TM Resource Adapter v. 10.20 RAR contains the convID, useConvID and convEnded properties in the interactionSpec, and these properties can be used to support conversational applications.
