Since former Library projects are not available in the Developer Studio, you have to transform the old Library projects into Enterprise Application (EAR) projects. This procedure describes the steps to do it.
For more information about the analogous case with Development Component projects, see Migrating J2EE Library DC to Enterprise Application DC.
You have a Library project created with an older version of the SAP NetWeaver Developer Studio.
Import the existing Library project in the Developer Studio (using the File →Import wizard).
Create new EAR project.
Select the EAR project in the Project Explorer.
In the context menu, choose Properties→Java EE Module Dependencies.
Choose Add JARs and select the JAR file archiving the Library project.
Choose OK.
Redirect all previous references to the old libraries to the new Enterprise application EAR
When the EAR project is built, the library JAR file is added to the application EAR file.
