Separate JSF and JSTL JAR files and implementation JAR files are also provided in the WL_HOME/server/lib/api.jar file. You can reference these JAR files for compilation purposes or when using other utilities while developing Web applications.


The JSF and JSTL libraries are bundled as WAR files and are located in the WL_HOME/common/deployable-libraries directory. The JSF libraries include the JSTL JAR files for convenience, so that if an application references a JSF library, it automatically gets JSTL support as well.
