Re: [rules-users] Upgrade to Drools 5 - loss of performance

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) ...
