Re: [rules-users] Caching of JBoss Rules bytecode field readers

I found a link that might explain what is happening with the problem I described in another posting (included below): http://jira.jboss.com/jira/browse/JBRULES-1009 Mark Proctor, if you read this posting, can you please explain in more detail how and why JBoss Rules generates bytecode field readers and caches them by string name? I would appreciate it. Could this explain the issue I'm experiencing as described below? I have scoured the documentation and have tried many different approaches to solving this problem, to no avail. I absolutely can not get the new version of a .drl file to load with just an application restart in Tomcat. I have to restart Tomcat each time. In my mind, this has to be a classloader issue. I just don't know how to get around it. I would really appreciate any help!

In my implementation, the rulebase is cached the first time it is used in my application, but when I add new rules to the source file and rebuild my application then redeploy it on Tomcat, the new version of the rules don't get loaded into the rulebase. Why and how is an older version of the rules being loaded into the rulebase when I redeploy my application in Tomcat? As FYI, I have developed a business rules service that initializes the rulebase upon a Spring container startup by loading the drl file from the classpath. Is there an internal Drools static cache that is scoped to something other than my application? The only thing I can do to load the new rules is restart Tomcat. When I do this, the new version of the drl source file is loaded and used, so I'm thinking the problem I'm having is somehow related to the class loaders Tomcat uses, but I can't find information about what Drools might be doing internally with a static cache or something like that. Can anyone explain what might be happening and how to configure Drools and/or my application to get around this problem I'm having? I definitely appreciate any help you can provide!
