Take a look at the org.drools.rule.JavaDialectRuntimeData class in drools-core. It contains a Map field called "store". All bytecode generated is stored in there, but there is no built-in way of dumping it. So either your tool allows you to inspect it in memory, or you change the class to dump it somewhere. Take a look at the writeExternal() method to understand how we dump it during kbase serialization.
