Sample Applications and Code Examples

JMS 2.0 Simplified API

JMS 2.0 is a completely overhauled release of the API, which applies modern programming techniques to make the use of JMS even easier. Using the simplified API to send and receive messages, dozens of code lines can be cut from JMS applications, making code development and maintainability even easier. The updated API also includes enhancements to message subscriptions, delivery delay, and more.

Test Domain

Use the WebLogic Server Examples domain to try out your own applications. By default, this directory is located in ORACLE_HOME/user_projects/domains/wl_server, where ORACLE_HOME represents the directory you specified as the Oracle Home when you installed WebLogic Server; for example, C:\Oracle\Middleware\Oracle_Home.

You can use the WebLogic Server instance you are running right now to try out your JSPs, servlet or other Java Platform, Enterprise Edition (Java EE) Applications. See the Fast Track Deployment and Administrator Guide.

WebLogic Server API Examples

The API examples demonstrate Java EE and WebLogic Server features. Each example comes with source code, instructions for building and running the examples, and ant scripts to automate the build process.
