Building and Deploying the Library 
Use
In this step you build and deploy the Java library on the AS Java.
Prerequisites
You are in the J2EE Development perspective in the J2EE DC Explorer view.
Procedure
DC Build
...
1. In the context menu of your J2EE Library DC, choose Development Component ® Build...
The dialog window Build Development Components appears which contains two entries.
2. Select both entries (if necessary) and confirm with OK.
The component build now creates a deployable archive named example.org~appl~tax.sda, which wraps the archive example.org~appl~tax~calc~tax.jar of component appl/tax/calc.
Deployment
...
1. Select example.org~appl~tax.sda in the J2EE DC Explorer view.
2. From the context menu, choose Deploy to J2EE Engine.
This will deploy the library to the configured runtime system.
3. Monitor the ongoing process in the Deploy Output and General User Output views.
For the deployment, the AS Java must be running.
Result
The library is deployed to the AS Java.
