Overview

Step 3: Name the Library

3. Add the Library

• Project-level library — makes JARs available only to a specific project; best for project-scoped dependencies.
• Application-level / Workspace-level library — share libraries among multiple projects in the same application/workspace.
• Global library — IDE-wide; useful when multiple applications across workspaces need the same libraries.
• Maven-managed dependencies — preferred for reproducible builds, transitive dependency resolution, and CI/CD pipelines.
• Module/classpath vs. deployment bundling — runtime availability depends on packaging: web apps need JARs in WEB-INF/lib, EAR modules in lib or module libs; for standalone Java apps JARs must be in classpath or packaged with a runnable distribution.
• JDeveloper ADF specifics — when building ADF apps, prefer creating library JARs and declaring them as shared libraries in the ADF application or using the ADF Library Jar mechanism.
