Hi,

 

It appears that nested inner classes are not implemented correctly. I am getting a compile error even when the rule is rewritten to include the import statement :

 

package com.sample

import com.sample.OuterClass.InnerClass.InnerInnerClass;

Yes, most likely we don't have the logic to reflect on inner inner classes. See this class to understand how we resolve a string name to a Class instance:
http://anonsvn.labs.jboss.com/labs/jbossrules/branches/4.0.x/drools-core/src/main/java/org/drools/base/ClassObjectType.java

Maybe you can make a test case and a patch for us for the 4.0.x branch. I guess make it generic enough so that it can work with any numbers of nesting. Although I may be concerned on how this might impact reflection lookup.

rule "Inner Class Test"

when

InnerInnerClass( )

then

System.out.println( "" );

end

Importing the class was the first thing I tried. That did not work either.

 

Thanks,

you need to import the inner classes, look at the HelloWorld example which uses a nested Message object and see how it's imported. Inner classes definitely work, let me know if inner.inner classes don't.

Hi,

 

I have a rule that looks like this :

 

package com.sample

rule "Inner Class Test"

when

com.sample.OuterClass.InnerClass.InnerInnerClass( )

then

System.out.println( "" );

end

The inner class referenced by this rule is defined like this:

package com.sample;

public class OuterClass {

   public class InnerClass {

      public class InnerInnerClass { }

   }

}

I am getting an error "Unable to resolve ObjectType 'com.sample.OuterClass.InnerClass.InnerInnerClass'".

What am I doing wrong? I am using XMLBeans-generated POJOs in my application and these POJOS contain a lot of deeply nested inner classes and these are giving me compile-errors in Drools.

Thanks,

Narendra
