Hi, We are an insurance company employing drools ( version 2 currently) for policy validation rules and for reading policy specific rates from spreadsheet using drools. We are currently running in to memory issues when we execute the compiled JAR ( including the drools compiled files), as there are lot of rules fired for different versions of policy rating. My question here is :- Is there any scope of resolving this memory issue with upgrade of drools package from version 2 to version 5? Will the compiled DRLs in Drools 5 be more compressed compared to Drools 2? I have been trying to upgrade to Drools 5 by adding the necessary jars for compilation. But unfortunately I am gettng few errors on spreadsheet and DRL compilation. Is there more to work on the upgrade? One of the errors I frequently get for spreadsheet comparison is something like below: *Invalid character input "?" (character code 65533)* Please clarify my above questions. Thank you much, Steve ** _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Thank you much. Mauricio. Thats right that there are lot of changes till version 5. How about my first question? Will the memory of the compiled rules have any effect on it? _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
