Call a Java Class on Server start-up

[abhishek pendkay]

Hi All,

I am new to WebLogic. I am using WebLogic 10.3. I want to call a JAVA class on server startup. This class and the dependent classes are all bundeled into a JAR. How do I do this..??

Thanks

Does the app include a web app part? If so, then that's what ServletContextListener classes are for.

No it is not a web-app nor is it connected with any servlet or JSP page so I guess ServletContextListener would not help me.

The class is a simple java class which acts like a scheduler and which should start with server start-up and it depends on few other class files. All of these class files are packaged in a jar file. Is there a way I can tell Weblogic to read that jar and call my class (it has a main method) at startup..??

WebLogic Server console has a place where you can enter the fully qualified Java class name. This class gets called at the time of server startup. All you have to ensure is that the class file or the jar (which contains the class) is present in the classpath.

Both Startup and Shutdown Classes are provided for doing life cycle maintenance activities.

Hi.,

Implement your jar as a JavaAgent and set javaagent parameters in server start up file(bat or sh)
