Hi,

Thanks for the help!

I have tried implemented your idea by creating a method that compiles the rules resources (DRL and RF files). But I keep getting a

java.lang.RuntimeException: java.io.EOFException

error when I call kbuilder.add(ResourceFactory.newFileResource("/some/file.pkg"), ResourceType.PKG); 

Any ideas?

Yes, you can compile your rules once and save them as binary files. Here is a code snippet to do that:

 KnowledgePackage pkg = (KnowledgePackage) kbuilder .getKnowledgePackages().iterator().next();

                FileOutputStream out = new FileOutputStream("/some/file.pkg");

try {

DroolsStreamUtils.streamOut(out, pkg);

} finally {

out.close();

}

The code above only uses kbuilder's first package.

The way you load a binary package is the same as you do for DRL files:

kbuilder.add(ResourceFactory.newFileResource("/some/file.pkg", ResourceType.PKG); 

Hope you find this useful!

Thanks for your reply!

No particular reason. Is there a better of going about this – avoid compilation of rules everytime?

Is there any reason why you need to compile the rules every time your app starts?

Hi guys,

I have a drools application running that takes about 7 seconds to run. 5 seconds of this time is used in parsing 2 DRL files that 200kb (6200 lines of code) and 34kb (1400 lines of code). Do you guys have any tips or any techniques that I can use to improve performance?
