JBossCache 2.0 with JBoss AS 4.2.1 problems

[navjeetc]

Is it possible to use JBossCache with JBoss AS 4.2.1?

As per JBoss Cache 2.0.0 docs somethings may not work as quoted below:

It is possible to deploy a JBoss Cache 2.0 instance in JBoss AS 4.x (at least in 4.2.0.GA; other AS releases are completely untested). However, the significant API changes between the JBoss Cache 2.x and 1.x releases mean none of the standard AS 4.x clustering services (e.g. http session replication) that rely on JBoss Cache will work with JBoss Cache 2.x. Also, be aware that usage of JBoss Cache 2.x in AS 4.x is not something the JBoss Cache developers are making any significant effort to test, so be sure to test your application well (which of course you're doing anyway.)

I downloaded JBossCache 2.0.0 GA, copied all the jars from lib folder to JBOSS_CONFIG/lib folder (I am using all configuration) and then copied replSync-service.xml from etc/META-INF to JBOSS_CONFIG/deploy folder and I get the following error during server startup:

Did I miss any step or is this a compatibility issue?

Please post your config file (use the "Code" button). The etc/replSync-service.xml file does not include a cache loader.

Now I am using local-eviction-cacheloader-service.xml from etc/META-INF but getting the same error.

Earlier in the log there should be an ERROR logging and a stack trace from when this error actually happened. Please post it.

You can't deploy a JBC 2.0.0 cache in JBoss AS as a JMX MBean the way you did with JBC 1.x. You will need to wait for AS 5 for this.

Until then you can instantiate and use JBC 2.0.0 programatically in your code.
