[rules-users] Time Taken To Load Rule Resource

[Esteban Aliverti]

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!
