Start and stop a deployed J2EE library

Before you begin

You must install a J2EE library before you can start it. See Install a J2EE library

Starting a J2EE library makes it available to the modules and applications deployed to WebLogic Server that reference the library; stopping the library makes it unavailable.

When you start a J2EE library, you can make it immediately available to clients, or you can start it in Administartion Mode to first ensure that it is working as you expect. Starting in Administration mode allows you to perform final ("sanity") checking of the library directly in the production environment without disrupting clients.

Similarly, you can stop a J2EE library so that no clients can use it, or you can stop it in Administration Mode so that only administrative tasks can be performed.

Stopping a library does not remove its source files from the server; you can later redeploy (also called update) a stopped library to make it available to deployed WebLogic Server modules and applications once again.

To start or stop an installed J2EE library, follow these steps:

In the left pane of the Console, click Deployments. A table in the right pane displays the installed applications, modules and J2EE libraries. J2EE libraries are specified with the Library entry in the Type column.
In the table, locate the J2EE library you want to start or stop.
Check the box to the far right of the J2EE library.
Click the Start button at the top of the Deployments table to start a stopped library. Similarly, click the Stop button to stop a library.
When you start a J2EE library, you must pick one of the following options:
- Servicing all requests: Specifies that WebLogic Server make the library immediately available to all modules and applications that reference it.
- Servicing only administrative requests: Specifies that WebLgoic Server make the library available in Administration Mode only.
When you stop a J2EE library, you must pick one of the following options:
- When work completes: Specifies that WebLogic Server wait for the library to finish its work and for all modules or applications that are currently using it to stop.
- Force stop now: Specifies that WebLogic Server stop the library immediately, regardless of the work that is being performed and the modules and applications that are currently using it.
- Stop, but continue servicing administrative requests: Specifies that WebLogic Server stop the library once all its work has finished, but to then put the library in Admnistrative Mode so it can be accessed for administrative purposes.
