In order to take advantage of WebLogic-specific features or settings, the project must be targeted to a WebLogic server runtime.
To target a WebLogic server runtime, either:
When targeting a WebLogic server runtime, the appropriate JAR files will be added to the library classpath and WebLogic-specific deployment descriptors will be created as needed. WebLogic EJB validators become enabled for EJB projects (not applicable in IBM Rational Web Developer). All modules in an enterprise application should have the same server target.
Tip: Since WebLogic Server only supports up to J2EE 1.3, set Highest J2EE version used for development to 1.3 in Window > Preferences > J2EE. This makes it easier to target a WebLogic server runtime.
