Creating and Deploying a Library 
Purpose
The component tech/tax/calc is a simple Java library and therefore cannot be deployed directly to the AS Java. The developer USER1 in this step continues wrapping the library with a Java library component.
Process Flow
For this step, you have to complete the following procedures:
...
1. Create a new development component (DC) for the library.
More information: Creating a New Development Component.
2. Declare the use of another DC – that is, the DC you created in the previous steps of this tutorial.
More information: Declaring the Use of Another Development Component.
3. Build and deploy the new library.
More information: Building and Deploying the Library.
4. Check in the changes to the DTR and activate them in the CBS.
More information: Checking in the Changes to the DTR.
Result
You have a Java library as a development component built and deployed on the AS Java.
