Error: StateTransferVersion 123 only supports transferring

[jyoonyang]

Hello,

I am getting the following error at startup. Any idea?

12:17:42,175 INFO [TreeCache] locking the /ticket subtree to return the in-memory (transient) state
12:17:42,175 ERROR [RpcDispatcher] failed invoking method

I suspect it has something to do with calling registerClassLoader() and activateRegion(). I tried adding an empty HashMap in the node. But same error...

public void ini() {
...
 cache.put(FQN_TICKET, new HashMap());

 cache.registerClassLoader("/" + FQN_TICKET, this.getClass().getClassLoader());
 cache.activateRegion("/" + FQN_TICKET);
...
}

Thanks,
Jennifer

What JBC version were you running?

JBC has a config attribute "StateTransferVersion" or in later releases "ReplicationVersion". Sounds like the cache has this set to "1.2.3" to allow interoperability with a cache instance running JBC 1.2.3 or earlier.

The registerClassloader()/activateRegion() API are 1.2.4 features that will not interoperate with 1.2.3. If your "ReplicationVersion" is set to "1.2.3", you cannot use these features.

Check and make sure you aren't setting attributes StateTransferVersion or ReplicationVersion in your config file and that you aren't calling TreeCache.setStateTransferVersion() or TreeCache.setReplicationVersion().

Brian,

We had StateTransferVersion set as

<attribute name="StateTransferVersion">130</attribute>

After removing it as you suggested, I don't see the error anymore.

Thank you,
Jennifer
