Check out 'Spring Modules' subproject - it has a DROOLS integration module. Haven't used it myself yet, so not sure whether it's mature/compatible with most recent release. https://springmodules.dev.java.net/docs/reference/0.7/html/jsr94.html#d0e570 9 https://springmodules.dev.java.net/ Vlad -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Niyas Sent: 19 February 2007 09:49 To: rules-users@lists.jboss.org Subject: [rules-users] Drools With Spring Framework Problem Hi all, I am in need of integrating Drools JBoss Rule Engine with Spring Framework. I have tried sample rule engine examples in the Drools in the standalone with the help od drools IDE for eclipse 3.2. And I also tried some example in the Spring Framework,to know how it works. I have tried some examples in IOC, MVC and JDBC in the spring framework. Now, I want to use both Drools and Spring Framework in such a way that Spring will have the MVC application and it should validate the rules, which written in the drools (.drl) I don't know how to begin with/what are he configuration files needed to setup. PLease if anyone have the sample coding on Drools with Spring or any other links willl be very useful. And also, guide me what are the things need to be know for Spring with Drools. While I have searched in google, lots of things came up like: Use JSR94... (which is mentioning to configure RuleServiceProvider, RuleRuntime, RuleSet..and others..which seeme to be confusing and not clear) Whether there are any API for drools with spring that DROOLS is supporting..like org.drools.spring.metadata.ArgumentMetadataSource. I don't find these Drools API section http://labs.jboss.com/file-access/default/members/jbossrules/freezone/docs/3 .0.5/apidocs/index.html _______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users _______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
