Object instantiation exception in TreeCacheAop replication

[henryzh126]

Hi, I'm new to this interesting project. When testing replication, TreeCache is ok but TreeCacheAop throws object instantiation exception:
failed creating instance of com.xxx.Customer; - nested throwable: (java.lang.InstantiationException: com.xxx.Customer);

code is simple:

TreeCacheAopMBean cache = ServiceLocator.getInstance().getTreeCacheAop("testTreeCacheAop");
if (!cache.exists(fqn))
{
...
}else
{
Customer c = (Customer)cache.getObject(fqn); // Exception throws here
...
}

Note that it works fine locally, but after replicated(A->B), B get that problem, both A and B using same stuff and the object is not Serializable, also I don't use farming, but deploy .ear and tree-aop-service.xml under /deploy of both machines respectively. Whatever using runtime interceptor or pre-compile(aopc), get the same result.

So what's the problem...

You will need to post more details of your code. For example, did you do a putObject first? The best way is to thru the tutorial making sure you understand the example there first.

Thanks for reading, ben.

Now I got it. The problem comes from a user defined constructor in the object to be cached, I suspect due to the fine-granularity character of replication, that's why it works fine locally but got object instantiation exception if the cache is replicated from other member.

Thank you.
