Jolt

[Attributes and Console Screen Reference for Jolt]

Jolt is a Java-based client API that manages requests to BEA Tuxedo services via a Jolt Service Listener (JSL) running on the Tuxedo server. The Jolt API is embedded within the WebLogic API, and is accessible from a servlet or any other BEA WebLogic application. The Jolt Java client class library can be used in HTTP servlets running in WebLogic Server and provides an interface between HTML browser clients and BEA Tuxedo services.

 

Configuring Jolt for WebLogic Server

The following sections provide information on how to configure WebLogic Server to interoperate with Tuxedo using Jolt. Consult your BEA Product Documentation for detailed information on how to configure and use Jolt.

Set Your Environment

You must update your CLASSPATH environment variable used by your WebLogic Server and command-line shells to include the following files from your Tuxedo installation:

Create a Jolt Startup & Shutdown Class

You must create a Startup and a Shutdown class to establish and terminate the connection between Tuxedo and WebLogic Server. WebLogic Server uses the PoolManagerStartUp class to establish a connection to Tuxedo whenever the WebLogic Server is started or restarted. The shutdown class instructs WebLogic Server to invoke the PoolManagerShutDown class to disconnect the Jolt session pools from Tuxedos when the WebLogic Server shuts down. For more information on Startup and Shutdown classes, see Startup and Shutdown Classes.

  1. In the left pane, expand the Deployments folder.
  2. Click on the name of the Startup & Shutdown folder.
  3. Click on the Configure a new Startup Class ... link.
  4. In the Name field, enter the name for your Jolt Startup class. Example: MyJoltStartupClass.
  5. In the ClassName field, enter the following: bea.jolt.pool.servlet.weblogic.PoolManagerStartUp
  6. Click to enable Failure is Fatal.
  7. Click Create.
  8. Target and Deploy your Jolt Startup class and click Apply.
  9. Click on the name of the Startup & Shutdown folder.
  10. Click on the Configure a new Shutdown Class ... link.
  11. In the Name field, enter the name for your Jolt Shutdown class. Example: MyJoltShutdownClass.
  12. In the ClassName field, enter the following: bea.jolt.pool.servlet.weblogic.PoolManagerShutDown
  13. Click Create.
  14. Target and Deploy your Jolt Shutdown class and click Apply.

  6. Click the User tab to create a user identity. See Configuring a User Security Identity.
  7. Restart the Administration Server so that your changes can take effect.

Assign Jolt Connection Pools to a Server

  1. Click the instance node in the left pane under Jolt to select a connection pool for assignment. A dialog displays in the right pane showing the tabs associated with this instance.
  2. Click the Target and Deploy tab.
  3. To assign a connection pool to a selected server, click one or more servers in the list of Independent Servers that has an empty check box. A check mark is displayed next to each server assigned to a Jolt connection pool.
