Class GridWeblogicStartup

java.lang.Object
  org.gridgain.grid.loaders.weblogic.GridWeblogicStartup

All Implemented Interfaces:

GridWeblogicStartupMBean, weblogic.common.T3StartupDef

@GridLoader(description="Weblogic loader")
public class GridWeblogicStartup
extends Object
implements GridWeblogicStartupMBean

GridGain loader for WebLogic implemented as a pair of start and shutdown classes. This is a startup class. Please consult WebLogic documentation on how to configure startup classes in Weblogic. Weblogic loader should be used for tight integration with Weblogic AS. Specifically, Weblogic loader integrates GridGain with Weblogic logging, MBean server, and work manager (JSR-237).

The following steps should be taken to configure startup and shutdown classes:

1. Add Startup and Shutdown Class in admin console (Environment -> Startup & Shutdown Classes -> New).
2. Add the following parameters for startup class:
   • Name: GridWeblogicStartup
   • Classname: org.gridgain.grid.loaders.weblogic.GridWeblogicStartup
   • Arguments: cfgFilePath=config/default-spring.xml
3. Add the following parameters for shutdown class:
   • Name: GridWeblogicShutdown
   • Classname: org.gridgain.grid.loaders.weblogic.GridWeblogicShutdown
4. Change classpath for WebLogic server in startup script: CLASSPATH="${CLASSPATH}:${GRIDGAIN_HOME}/gridgain.jar:${GRIDGAIN_HOME}/libs/"

For more information see Configuring and Starting GridGain and Startup and Shutdown Classes.

Note: Weblogic is not shipped with GridGain. If you don't have Weblogic, you need to download it separately. See http://www.bea.com for more information.

How to use AOP with Bea WebLogic

The following steps should be taken before using Gridify annotation in applications on Bea WebLogic.

AspectJ AOP

1. Add GridWeblogicStartup with configuration described above.
2. Classpath of the WebLogic should contain the ${GRIDGAIN_HOME}/config/aop/aspectj folder as well as as all GridGain libraries (see above).
3. Add JVM option -javaagent:${GRIDGAIN_HOME}/libs/aspectjweaver-1.5.3.jar (replace ${GRIDGAIN_HOME} with absolute path) into startWeblogic.{sh|bat} script which is located in "your_domain/bin" directory.

Note: Bea Weblogic works much slower if you use AspectJ with it.

Spring AOP

Spring AOP framework is based on dynamic proxy implementation and doesn't require any specific runtime parameters for online weaving. All weaving is on-demand and should be performed by calling method GridifySpringEnhancer.enhance(Object) for the object that has method with Gridify annotation.
