[JBoss AOP] - Re: howto hotswap ?
by flaviarnn
Hi, Birgen!
To enable the hotswap feature, you need to execute you system with the java 5 agent enabled, and pass the "hotSwap" parameter to this agent, like this:
java your_app your_params -javaagent:jboss-aop-jdk50.jar=-hotSwap
You can have more instructions on this page:
http://labs.jboss.com/portal/jbossaop/docs/1.5.0.GA/docs/aspect-framework...
To use the hotswap, all you need to do is invoke the dynamic AOP operations provided by JBoss AOP. Everytime you add or remove an aspect to the system the changes will be performed through hotswap.
To give you an example, suppose you want to add an Interceptor to JBoss AOP. Consider your interceptor is called MyInterceptor. So, you can add both to the system like this:
| // create a binding, defining a pointcut expression
| AdviceBinding binding = new AdviceBinding("execution(public * POJO->method())", null);
|
| // this line associates MyInterceptor to your advice binding
| binding.addInterceptor(MyInterceptor.class);
|
| //finally, add this binding tho the JBoss AOP system
| AspectManager.addBinding(binding);
|
|
The last line deploys the binding, and results in the hotswap of all classes affected by this binding. If you want to specify a cflow constraint, you can pass the cflow expression as the second argument of the AdviceBinding constructor.
Another example adds a binding associated with an advice, instead of an interceptor (suppose your advice method is MyAspect.myAdvice()):
| // create a binding again, defining a pointcut expression
| AdviceBinding binding = new AdviceBinding("execution(public * POJO->method())", null);
|
| // these lines deploy your aspect to the system, the parameter is the name of your class; the second parameter should not be used by end users
| AspectFactory af = new GenericAspectFactory("MyAspect", null);
| AspectDefinition ad = new AspectDefinition("MyAspect", Scope.PER_VM, af);
| AspectManager.addAspectDefinition(ad);
|
| // this line adds the advice to this binding
| binding.addInterceptorFactory(new AdviceFactory(ad, "myAdvice");
|
| //finally, add this binding tho the JBoss AOP system
| AspectManager.addBinding(binding);
|
Notice you can define the Scope as you wish, like Scope.PER_CLASS, Scope.PER_INSTANCE, and others.
Besides, you can play along with these examples, adding interceptors and advices to one single binding.
To remove the binding, invoke the removeBiding method of AspectManager class.
If you have any more questions, or problems to use hotswap, please, ask again.
Regards,
Flavia

Since I have the same ejb's in two different clusters, I am using the jboss.xml approach with
<clustered>true</clustered>
for each of my sesion beans.
see: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=91189
The jboss failover code does not seem to be working though, and I get the following exception stack trace when I shutdown one of the servers in the cluster that the client had been making calls to:

note that loadObject is the session bean call. and that is where it is failing. As soon as I create a new InitialContext using port 1100 and then lookup the session bean again, the call goes through. Although, I thought that the stub was supposed to do this for me.
here is the entry in jboss.xml for one of my sesion beans:
| <session>
| <ejb-name>PersonManagerSessionImpl</ejb-name>
| <clustered>true</clustered>
| <cluster-config>
| <partition-name>${jboss.partition.name}</partition-name>
| <load-balance-policy>org.jboss.ha.framework.interfaces.FirstAvailable</load-balance-policy>
| </cluster-config>
| </session>
