Creating Use Dependencies on Another
Development Component
Use
In this step, you create a use dependency for the TaxUIController class to the ITaxCalculator and TaxFactory from the development component technology/tax/calculator. This is required to build the TaxUIController class.
Prerequisites
● You have restarted the SAP NetWeaver Developer Studio to refresh the active DCs list.
● You are in the J2EE Development perspective in the J2EE DC Explorer view.
Procedure
Add Dependency to Another DC
...
1. Under ...appl~tax~servlet..., open the node DC MetaData → DC Definition.
2. Select the node Used DCs. From the context menu, choose Add Used DC.
3. From the component tree in the Active tab page, select the node of your development configuration → example.org_technology → tech/tax/calc → DC MetaData → Public Parts → api.
4. Select only the checkboxes Build Time and Run Time – remove other selections if necessary.
5. Choose Finish.
The TaxUIController class is rebuilt automatically and all compilation errors should vanish.
Add Modules
...
1. Go to the J2EE Development perspective in the J2EE DC Explorer view.
2. Select the node of the Enterprise Application Project (...~appl~tax~...) and from the context menu, choose Add Modules.
3. In the dialog that appears, select the Servlet project (...~appl~tax~servlet...) and choose OK.
You now add the Servlet to your Enterprise Application.
Up to now, the Enterprise Application has only one compile time dependency to tech/tax/calculator. In order to run this application, you must also create a runtime dependency to the J2EE component technology/tax.
Create a New Reference
...
1. Go to the J2EE Development perspective in the J2EE DC Explorer view.
2. Open the entry application-j2ee-engine.xml in your Enterprise Application Project (...~appl~tax~...).
3. In the editor that appears, choose the General tab.
4. Select References.
5. Choose Add.
A dialog box appears.
6. Choose Create New...
7. For the new reference specify:
Data |
Value |
Referenced Target |
tech/tax |
Reference type |
hard |
Reference target type |
library |
Provider Name |
example.org |
8. Save the file.
Result
You have created the dependencies to the public parts of the other development component. Also, you have managed the required references between the files in the different DCs.
