Re: [rules-users] 4.0.0.MR3 Problems

Using the string you have there and reflection the system tries to load the JavaDialect, as long as its in your classpath it should work. The code to do this is straight forward and is in PackageBuilderConfiguration: public DialectRegistry buildDialectRegistry(PackageBuilder packageBuilder) { DialectRegistry registry = new DialectRegistry(); ClassLoader classLoader = Thread.currentThread().getContextClassLoader(); for ( Iterator it = this.dialects.entrySet().iterator(); it.hasNext(); ) { Entry entry = (Entry) it.next(); String str = (String) entry.getKey(); String dialectName = str.substring( str.lastIndexOf( "." ) + 1 ); String dialectClass = (String) entry.getValue(); try { Class cls = classLoader.loadClass( dialectClass ); Constructor cons = cls.getConstructor( new Class[]{PackageBuilder.class} ); registry.addDialect( dialectName, (Dialect) cons.newInstance( new Object[]{packageBuilder} ) ); } catch ( Exception e ) { throw new RuntimeDroolsException( "Unable to load dialect '" + dialectClass + ":" + dialectName + "'" ); } } return registry; } I've know idea why this is failing for you, let me know what you find.
