Re: [rules-users] Unable to load dialect java from Ant task

Hi all, I have a perfectly running Eclipse 3.3 with DRools 4.0.4 and JDK 1.5.14. The rules are compiled with a post build Ant task which uses Janino (need it for Tomcat compatibility). Now OUTSIDE Eclipse it seems I cannot use that Ant task to save my life :( I tried switching from Janino to the default compiler, same thing. I always get this infamous error: BUILD FAILED E:\buildRules-hudson.xml:30: RuleBaseTask failed: Unable to load dialect 'org.drools.rule.builder.dialect.java.JavaDialectConfiguration:java' at com.csc.ezbook.eztarif.rules.DroolsCompilerAntTaskStandalone.execute (DroolsCompilerAntTaskStandalone.java:163) at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:288) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl. java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke( DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.apache.tools.ant.dispatch.DispatchUtils.execute(DispatchUtils.java :105) at org.apache.tools.ant.Task.perform(Task.java:348) [...] Caused by: org.drools.RuntimeDroolsException: Unable to load dialect 'org.drools.rule.builder.dialect.java.JavaDialectConfiguration:java' at org.drools.compiler.PackageBuilderConfiguration.addDialect( PackageBuilderConfiguration.java:152) at org.drools.compiler.PackageBuilderConfiguration. buildDialectConfigurationMap(PackageBuilderConfiguration.java:140) at org.drools.compiler.PackageBuilderConfiguration.init( PackageBuilderConfiguration.java:117) at org.drools.compiler.PackageBuilderConfiguration.<init>( PackageBuilderConfiguration.java:94) at com.my.app.rules.DroolsCompilerAntTaskStandalone.getPackageBuilder( DroolsCompilerAntTaskStandalone.java:257) at com.my.app.rules.DroolsCompilerAntTaskStandalone.execute( DroolsCompilerAntTaskStandalone.java:136) That "DroolsCompilerAntTaskStandalone" is my task using the default compiler like this: PackageBuilderConfiguration conf = new PackageBuilderConfiguration(); conf.setClassLoader( loader ); PackageBuilder builder = new PackageBuilder( conf ); If I use Janino like below the error is exactly the same... PackageBuilderConfiguration pkgBuilderCfg = new PackageBuilderConfiguration(); pkgBuilderCfg.setClassLoader( loader ); JavaDialectConfiguration javaConf = (JavaDialectConfiguration) pkgBuilderCfg.getDialectConfiguration( "java" ); javaConf.setCompiler( JavaDialectConfiguration.JANINO ); PackageBuilder builder = new PackageBuilder( pkgBuilderCfg ); Again, in Eclipse all is working fine. I checked Ant's classpath, here it is: E:\apache-ant-1.7.0\bin\..\lib\ant-launcher.jar E:\apache-ant-1.7.0\lib\*.jar C:\Program Files\Java\jdk1.5.0_14\lib\tools.jar Here is how I provide a classpath: <taskdef name="rulescompiler" classname="com.my.app.rules. DroolsCompilerAntTaskStandalone" classpathref="droolsutils.classpath" /> <target depends="newfilesarethere" name="build" unless="rulesCompile. notRequired"> <rulescompiler srcdir="${THIS_PROJ}/src/com/my/app/rules" tofile="${THIS_PROJ}/build/classes/com/my/app/rules/ packaged.rules" classpathref="droolsutils.classpath" > <include name="*.drl" /> </rulescompiler> </target> The classpath I provide contains pretty much all libraries I use normally in the project, but I tried even to add ALL jar's from the Eclipse 3.3 install directory (that would include all DRools 4.0.4 libraries, with antlr and whatnot) I tried also with DRools 4.0.7, same behaviour... What does that mean and where is it coming from? Could it have issues with the tools.jar from Java 1.5.0_14?
