Overview

Oracle9i Application Server (Oracle9iAS) provides a fast, lightweight, highly scalable, and easy-to-use J2EE environment, Oracle9iAS Containers for J2EE (OC4J). OC4J is written entirely in Java and executes on the standard Java Development Kit (JDK) virtual machine. It provides a complete J2EE environment that includes a JSP Translator, a Java Servlet engine and an Enterprise Java Beans (EJB) container.

Oracle9iAS Containers for J2EE (OC4J)

OC4J provides the following key capabilities:

• Complete J2EE 1.2 API Support: OC4J provides complete support for all J2EE 1.2 APIs, including Enterprise JavaBeans (EJB) 1.1, Servlet 2.2, Java Server Pages (JSP) 1.1, JTA 1.0.1, JNDI 1.2, JMS 1.0,  JDBC 2.0, and JavaMail 1.1.2. 
• JDK-Based:  This release is certified to run against the standard JDK 1.2.x or JDK 1.3.x.  
• Lightweight: OC4J requires less than 10 Mb disk space and less than 20 Mb of memory. 
• Quick Installation and Configuration: OC4J can be installed quickly and easily (literally, less than 2 minutes) and uses standard XML file-based configuration facilitating rapid customization and maintenance. 
• Ease of Use: Java applications built with any development tool can be deployed against OC4J. OC4J supports standard J2EE deployment packages EAR, WAR, JAR or Client JAR files. Applications deployed with OC4J can be debugged using standard java profiling and debugging capabilities. 
• High Performance: OC4J is highly optimized, providing extremely fast response times and very high throughput rates. 
• Availability and Scalability: OC4J provides component clustering, load-balancing, and application state replication (fail-over). 
• Partial J2EE 1.3 API Support: OC4J provides a partial implementation of J2EE 1.3 APIs, including Public Drafts of both Servlet 2.3 and EJB 2.0 APIs. 
• Platforms Supported: OC4J is a feature of Oracle9iAS and is available on all standard operating systems and hardware platforms including Solaris, HP-UX, AIX, Tru64, Windows NT and Linux.
