I just upgraded our app from Drools 4 to 5 libraries. We just use the rules engine with DRL. The performance of the engine on our rulebase is unacceptably slow. I assume there is something we need to do to our rules or the way we are configuring the engine to fix this. I don't see anything in the release notes about backwards compatibility issues. I would very much appreciate it if someone would direct me to any documentation that explains what needs to be done so our 4.0 rules perform at least as well as they did before the upgrade?

Edson, I figured I must have missed some docs explaining changes required for the upgrade. If I suspected this was an inherent problem with the 5.0 release I'd have supplied lots of info. I am inferring from the response that there are no known issues with 5.0 upgrade so I'll do my own investigation for a while. Let's hope I find something unrelated to the Drools.

How much slower is that? 10%, 100%, 1000%? Also, we need a description of your use case: what kind of rules do you use, how many rules, how many facts, etc. Finally, we need a way to reproduce the problem. So, if you can provide more info, we might be able to help. []s Edson 2009/5/28 Scott Reed <sreed(a)avacoda.com&gt; > I just upgraded our app from Drools 4 to 5 libraries.

Another change that occurred in parallel with the upgrade was responsible for the upgrade. MY apologies for the false alarm. I am now seeing a problem with "Unable to load dialect ... JavaDialectConfiguration" - it appears to be looking for the Eclipse JDT jar file. However, I have never required that before. I use the Eclipse plugin but have not needed the JDT jar in the deployed app - doing fine with drools-compiler. I can start a new thread for this issue if it's going to take more than one reply to address this. Here's the drools dependencies in my classpath: antlr-runtime-3.1.1.jar drools-api-5.0.1.jar drools-compiler-5.0.1.jar drools-core-5.0.1.jar joda-time-1.6.jar mvel2-2.0.10.jar Here's the error output: Exception in thread "AWT-EventQueue-0" org.drools.RuntimeDroolsException: Unable to load dialect 'org.drools.rule.builder.dialect.java.JavaDialectConfiguration:java:org.drools.rule.builder.dialect.java.JavaDialectConfiguration' at org.drools.compiler.PackageBuilderConfiguration.addDialect(PackageBuilderConfiguration.java:274) at org.drools.compiler.PackageBuilderConfiguration.buildDialectConfigurationMap(PackageBuilderConfiguration.java:259) at org.drools.compiler.PackageBuilderConfiguration.init(PackageBuilderConfiguration.java:176) at org.drools.compiler.PackageBuilderConfiguration.<init>(PackageBuilderConfiguration.java:153) at org.drools.compiler.PackageBuilder.<init>(PackageBuilder.java:242) at org.drools.compiler.PackageBuilder.<init>(PackageBuilder.java:142) at com.cbfp.findata.Rules.generateRuleBase(Rules.java:165) at com.cbfp.findata.Rules.addPackage(Rules.java:208) at com.cbfp.findata.Rules.createRules(Rules.java:64) ...

Edson, I wasn't clear. I am getting this dialect error when I run the app outside Eclipse. It works great in Eclipse.

I interpreted the dependencies file to say that both compilers are optional. I figured Drools-Compiler would do the compiling unless I wanted whatever special compiling features were offered by Eclipse or Janino.
