Re: [rules-dev] Drools on android -reply

Here's what I got working and when it failed .... it was just the basic 'hello world' kind of stuff: Worked: final KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); Died: // this will parse and compile in one step kbuilder.add(ResourceFactory.newClassPathResource("HelloWorld.drl", DroolsTest.class), ResourceType.DRL); LogCat: 01-02 13:13:17.684: E/AndroidRuntime(537): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.versaggi.android.droolsandroidtest/com.versaggi.android.droolsandroidtest.DroolsAndroidTestActivity}: java.lang.NullPointerException That's about as far as I could get. I think this DOC will probably help out .... https://github.com/cgreenhalgh/droolstest/blob/8ea1a06d9b1b38a40b1add7f98.... .. I had to re-compile the CompositeClassLoader.java file and then reinsert it into the drools-api-5.1.0.M2.jar file to get past this issue: "A small modification is needed in org.drools.util.CompositeClassLoader. Apparently, the Android JVM doesn't allow null as the parent classloader so I changed that to super(CompositeClassLoader.class.getClassLoader()) in the constructor, and that works fine." However I think that his other modifications aren't completely integrated into the drools-compiler-5.1.0.M2.jar or the drools-core jar files he provides just yet. ********************************* On Mon, Jan 2, 2012 at 2:11 PM, Wolfgang Laun <wolfgang.laun(a)gmail.com&gt;wrote:
