Can't get PojoCache annotations to work on JBoss AS5

[gerbrand]

Hello,

For the past two days I've spent (wasted) a lot of time to get the PojoCache working on JBoss AS 5.

I've added the PojoCache libraries to my JBoss server\all\lib directory and added a pojocache-service.xml . I could successfully retrieve the PojoCache.

No I want to the 'Replicable' annotation working. After some time I figured out AOP needs to be enabled.

I 've changed the aop.xml in my conf\bootstrap\ directory: enableLoadtimeWeaving=true


However now when I start JBoss I get the following error. I really don't have a clue why this happens and I'm a little bit frustated, so I hope someone can help.

Below is the error I get while starting up JBoss:

You should be added -javaagent switch on JAVA_OPTS in run.sh like this :
set JAVA_OPTS=-Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Dsun.lang.ClassLoader.allowArraySyntax=true -Djboss.platform.mbeanserver -javaagent:deployers/jboss-aop-jboss5.deployer/pluggable-instrumentor.jar

Thanks the reply to my slightly not to nice-written posting! For the moment I've used the Serializable objects - working on something else already. I'll try it out asap.

congratulate you,, i spend two days for the aop run too .
now the application is normal start up .
but how i retrive the pojocache . pls help me.

i retrive the pojochache as follow

JMXServiceURL url = new JMXServiceURL(
 "service:jmx:rmi://127.0.0.1/jndi/rmi://127.0.0.1:1090/jmxconnector");
 JMXConnector jmxc = JMXConnectorFactory.connect(url, null);
 MBeanServerConnection mbsc = jmxc.getMBeanServerConnection();
 ObjectName mbeanName = ObjectName.getInstance("jboss.cache:service=PojoCache");
 // 得到proxy代��直接调用的方�
 PojoCacheJmxWrapperMBean cache = (PojoCacheJmxWrapperMBean)MBeanServerInvocationHandler.newProxyInstance(mbsc, mbeanName,PojoCacheJmxWrapperMBean.class, false);

 PojoCache cache2 = cache.getPojoCache();

but unfortunate i get the error

Somehow JBoss tries to Serialize the PojoCacheImpl class.

Caused by: java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: org.jbo
ss.cache.pojo.impl.PojoCacheImpl

Do you have a reference to the PojoCache inside the java classes you try to put into the cache? Maybe that's the problem, the class that implements Serializable shouldn't use classes that are not Serializble.
Best to keep the class reletively simple, by using primive types and types such as Date, BigInteger, String inside the class.

you can look my code upon . i only want to get pojocache from mbean service. when run to

MXServiceURL url = new JMXServiceURL(
 "service:jmx:rmi://127.0.0.1/jndi/rmi://127.0.0.1:1090/jmxconnector");
 JMXConnector jmxc = JMXConnectorFactory.connect(url, null);
 MBeanServerConnection mbsc = jmxc.getMBeanServerConnection();
 ObjectName mbeanName = ObjectName.getInstance("jboss.cache:service=PojoCache");

 PojoCacheJmxWrapperMBean cache = (PojoCacheJmxWrapperMBean)MBeanServerInvocationHandler.newProxyInstance(mbsc, mbeanName,PojoCacheJmxWrapperMBean.class, false);

 PojoCache cache2 = cache.getPojoCache();

throw the error .

[tongzhao]

in jboss as 5 ,
the manner to get mbeanserver as follows can't use .

MBeanServerLocator.getMBeanServer

is there other method get the mbean server in the same jvm

The PojoCache I retrieve using the following code:

 PojoCache cache= getCacheManager().getPojoCache("jboss.cache:service=EJB3SFSBClusteredCache", true);
 synchronized (this.getClass()) {
 if (!pojoCacheStarted) {
 cache.start();
 pojoCacheStarted=true;
 }
 }

Using that code I retrieve a standard configured pojocache. The EJB cluster cache. That Cache is used by JBoss for clustered EJB's, I use the cache for my own purpose.

You can configure you're own cache too, by creating a PojoCache.xml file, and placing the file in the deploy directory or in your ear.

I've created weblog entry on this subject, see:
http://www.gerbrand-ict.nl/2009/03/lessons-learnt-using-jboss-500ga-clustering/

Considering the hits I get, I'm considering writing a proper tutorial on Clustering.

i have the pojocache-service.xml in my web-inf.
and start normal.

but why the error say PojoCacheImpl not serialize.

Not certain if the web-inf is the right location. Eitherway, if you use the pojocache-service.xml, you don't need the mbean server anymore.
That code is only needed if you don't use the xml file, and want to programmatically register the pojocache.

this is my service.xml

because i want to support cluster and stable. so i have my own service.xml

[tongzhao]

if stalbe. must usr jta .and jta is bundle with jboss as .

[tongzhao]

i can run normal pojocache2.0.0 and jboss 4.2.3.


client code must be

MBeanServer server = MBeanServerLocator.locateJBoss();
 ObjectName on = new ObjectName("jboss.cache:service=PojoCache");

 PojoCache cache = PojoCacheFactory.createCache("replSync-service.xml", false);
 PojoCacheJmxWrapperMBean wrapper = new PojoCacheJmxWrapper(cache);

 server.registerMBean(wrapper, on);
 wrapper.create();
 wrapper.start();

 PojoCache cache_ = wrapper.getPojoCache();
