The Eclipse JDT model includes the classpath container concept. A classpath container is a logicalcollection of Java libraries, i.e., JAR and ZIP files, that canappear on a project's classpath. MyEclipse provides you with many user-configurable classpath containers, including Generic JavaEE Libraries and many framework libraries, like JSF, JPA, Spring,Struts, etc.
Note: Runtime libraries are not deployed with your project.
The figure below depicts contents of a Java EE 6 runtime library.
To modify project libraries, do the following:
- Open the project Libraries preference page by selecting Windows>Preferences from the menu, expanding MyEclipse, and selecting Project Libraries.
- Select the library to modify, and use the Add or Remove
Custom JAR buttons to edit the contents as needed.
