[rules-users] Uploading the fact model to the DRools BRMS
When I upload a jar file to the DRools BRMS it does not get uploaded. When i try to get the clsses by the import statements it says the class cannot be found. Are there any special way of making the jar?Should that fact modelapplication include special libraries or etc ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] OutOfMemory with BRMS 4.0.3
Hello, I am using Drools BRMS 4.0.3 with tomcat 5.5.25, and I get OutOfMemory exceptions in tomcat regularly. I recently changed the java option of tomcat to add -Xmx512m, but it only resulted in taking a little more time before crashing (3 days, instead of 1 before). The server has nearly no access - it's a development server which is not a lot used at the moment - and there are only a few rules, for tests, so I really don't understand this error. I'm using java 1.5.0 on a linux server. The BRMS is accessed by web, to create and deploy the rules, and queried from another tool (on the same machine but in another server: in JBoss), to insert data in a workingMemory and execute the rules from the deployed package URL. I call the dispose() method on the StatefulSession at the end of the query (but this shouldn't be linked to this error, since this is in JBoss and the OutOfMemory occurs in tomcat...). Any idea?

Re: [rules-users] OutOfMemory with BRMS 4.0.3
Hi! Are you using the WorkingMemoryLogger? Here is some information from a previous mail thread (Drools 4.02 or 4.03 memory leak?) on this list: In 4.0.3, there is a memory leak with the use of WorkingMemoryLogger. Maybe it's that ?

I have a vague recollection that there is another file in which you need to list your fully qualified class names before they can be referenced by the BRMS.

Re: [rules-users] what is pluggable dialects
jack wu wrote: i read the documentation saying drools 4.x supports pluggable dialects, but i can't find anything else that explains what it is. i think by default i am using java dialect. and there is a MVEL dialect. is that it? i am trying to see if there is a way to not use java beans as fact objects. i have been looking to the MVEL website where they have a sample like this: Map vars = new HashMap(); vars.put(x, new Integer(5)); vars.put(y, new Integer(10)); Integer result = (Integer) MVEL.eval(x * y, vars); my question is if i use MVEL dialect, can i pass in a Map similar to the above for fact objects? Thanks. Dialects make no difference to what you can assert. The dialect is simple the lanage used to execute returnValue, inlne-evals, evals and consequences. You can choose Java or MVEL, or plugin your own. jack. Looking for last minute shopping deals? Find them fast with Yahoo!

Re: [rules-users] OutOfMemory with BRMS 4.0.3
No, I haven't, because initially I wanted it to be deployed in an environment distinct from my client classes, which are in jboss application server (but 3.2.8 for compatibility reasons...).
