Creating a scheduler resource reference

When you define schedulers in the server configuration, the object instance is bound into the global name space under the configured Java™ Naming Directory Interface (JNDI) name. You can use a resource reference to avoid manually coding this JNDI name into your application. Using a resource reference allows administrators to map applications to the appropriate schedulers.

About this task

You can alternatively create a scheduler resource reference by editing the XML directly. A Scheduler resource reference is a Java Platform, Enterprise Edition (Java EE) compliant resource that uses the class com.ibm.websphere.scheduler.Scheduler as the object type. For information regarding the XML file format, see the Java EE Specification.

Procedure

  1. Start an assembly tool, such as Rational® Application Developer.
  2. Open the Java EE perspective.
  3. Open your Enterprise JavaBeans (EJB) or Web module with the Deployment Descriptor Editor.
  4. Click the Reference tab.
  5. Click Add.
  6. Select the Resource reference option.
  7. Click Next.
  8. Complete the Reference fields as shown in the following properties:
    Name
    The reference name, for example, sched/MyScheduler. According to this example, the name you choose has a local reference name of java:comp/env/sched/MyScheduler.
    Type
    Select com.ibm.websphere.scheduler.Scheduler, and click OK.
    Authentication
    Select container.
    Description
    Any relevant description.
  9. Click finish.
  10. Optional: Enter a global JNDI name of a configured scheduler in the JNDI name field in the Bindings section of the Reference window. You can specify or override this value when you install the application.
  11. Save your changes to the deployment descriptor.

Results

A scheduler resource reference is now available to use within your application
