Re: [rules-users] Changing the java compiler level in drools
If you're trying to use generics in the RHS of a rule, I don't think playing with
the compiler setting will help. They weren't available in DRL last time I looked.
You may be better off writing a static method on a Java class or a global object, which
you can call out to. That way you can work with generics outside your DRL.
Unless anybody knows about this issue being sorted out in a newer version of Drools? :)

for me. I am trying to use generics in the consequence part.
Following is my code that I used to change the compiler level.
*Drools Version: 5.2.1 GA
JDK Version : 1.6*
*final Properties properties = new Properties();
properties.setProperty("drools.dialect.java.compiler", "JANINO");
properties.setProperty("drools.dialect.default", "java");
properties.setProperty("drools.compiler.lnglevel", "1.6");
PackageBuilderConfiguration packageBuilderConfiguration =
new PackageBuilderConfiguration(properties,(ClassLoader[]) null);
final KnowledgeBuilder knowledgeBuilder = KnowledgeBuilderFactory
.newKnowledgeBuilder(packageBuilderConfiguration);*
Let me know where I am going wrong.
Thanks for the help.
