About OC4J

Oracle Application Server Containers for J2EE (OC4J) is a program that allows J2EE applications to run on the Oracle Application Server. OC4J provides a lightweight, easy to use, high performance J2EE environment. The J2EE facilities provided by OC4J include an Enterprise JavaBeans (EJB) container, a Java Servlet container, and a JavaServer Pages translator and runtime (OJSP).

A standalone version of OC4J is included in the JDeveloper installation, and a minimal version is embedded in JDeveloper, giving three ways to run J2EE applications in an OC4J environment:

test applications in embedded OC4J by running and debugging them in JDeveloper
deploy applications for testing to standalone OC4J
deploy working applications to Oracle Application Server

Documentation about Oracle Application Server Containers for J2EE (OC4J), and other Oracle technology, is available online from the Oracle Technology Network (OTN) at http://www.oracle.com/technology/documentation/.
