I tried that .. I was able to reproduce same crash on android emulator .. default heap is 24M ( like any android device ). I tried raising it upto 400Mb in steps, but it failed everytime with same error .. but was able to sustain longer everytime i increase the heap. Seems that I can not go beyond 400m .. the emulator crashed !

In a meeting right now, but you could try Googling for ways to increase the heap size on Android?
I did a very quick search and it looked possible....

Thanks Mike !
It is failing after few seconds ( about 30-35 secs ) after I get the “Creating Package Builder ..” line on the console …I am not getting the next debug statement, but getting the exception instead. I am seeing a lot of garbage collection calls right after “Creating Package Builder …” line in the console before crashing, which tells me that the issue is probably related to heap/memory.
Here’s the snippet from my code.
System.out.println (“Creating Package Builder .. ”);
PackageBuilder builder = new PackageBuilder( cfg0 );
builder.addPackageFromDrl(new InputStreamReader(is)); // “is” is input stream for drl file
RuleBase ruleBase = RuleBaseFactory.newRuleBase();
ruleBase.addPackage( builder.getPackage() );
System.out.println (“Package added to rule base.. ”);

Congratulations Abhay!
When does your application crash? e.g. building package, inserting facts, firing all rules?
I'm not sure how much help I can be, but your advice might help others.
Unfortunately I'm not able to analyse the Android log :(
Cheers,

I am have now managed to get past all the compiler errors for Drools on android .. ( I think ) ☺ .
My app is failing ( crashing ) when run on android device. Looking at the log, appears to be a heap memory problem, can anyone see anything suspicious here in the android log, that may point to the drools code as suspect ?

The ride’s real fun ☺
Got apache harmony’s beans.jar to work .. now , when I am reading the serialized knowledgebase object on android, quite obvious, it is throwing this error –
java.lang.UnsupportedOperationException: can't load this type of class file
since my serialized knowledgebase object is in java format .. and not dex. Can this serialized version be converted into .dex format using the “dx” utility – pre or post serialization ? I tried the “dx” tool on the serialized object, but it doesn’t seem to understand the format.

That’s exactly what I am trying out at the moment .. option – b. Pre-compile, serialize and unserialize …I’ll share the results.
Also rule file’s there at the location mentioned. So that’s not a problem.
I’ve gone through the blog you mentioned … and as you indicated, it’s only jbpm .. no rules …

Preparing to be shouted down, but isn't it impossible to compile DRL on Android and the suggestion is to load pre-serialised KnowledgeBases?
Also, as another observation, are you sure the DRL was indeed found and the NPE is not caused by "com.ts.DBconnector.readKnowledgeBase(DBconnector.java:143)" perhaps passing a null to KnowledgeBuilder?
Have you looked at
http://blog.athico.com/2011/03/jbpm5-lightweight-running-on-android.html, which might give some pointers - although it is only jBPM and not rules themselves.
With kind regards,
Mike

You might try this:

props.put( "drools.dialect.java.compiler", "JANINO" );
KnowledgeBuilderConfiguration kbConfig =
KnowledgeBuilderFactory.newKnowledgeBuilderConfiguration( props, (ClassLoader[]) null );
Requires the janino jar in your classpath, which I have as

I am using drools 5.1.0
Let me explain what I am trying to do. I am trying to write a drools app on to android platform. In my app, I have added following jars in the application classpath -
antlr-runtime.jar
drools-api.jar
drools-compiler.jar
drools-core.jar
mvel2.jar
Do I need any other jar files ?
upon drilling down into the Null Pointer Exception, it appears that it is throwing NPE at following line inside RuleBuilder.java
RuleConditionBuilder builder = (RuleConditionBuilder)context.getDialect().getBuilder(ruleDescr.getLhs().getClass());
and on further drilling, I found that "context.getDialect()" is retuning NULL.
Then I put some debug inside PackageBuilder.java
upon drilling down for the error, found out that it is not able to set the context's dialect.
ctr.getDialect(pkgRegistry.getDialect()) gives "null" ...
DialectCompiletimeRegistry ctr = pkgRegistry.getDialectCompiletimeRegistry();
RuleBuildContext context = new RuleBuildContext(this, ruleDescr, ctr, pkg, ctr.getDialect(pkgRegistry.getDialect()));
Is there any default setting /configuration that I am obviously missing ?
what could be the problem ?

Which version of drools is this?
For drools 5.0.1 we just use maven to resolve the dependencies for us and it works fine. I can't obviously see any eclipse compiler in the jars that we distribute with our application.

> Subject: [rules-users] Drools in non-eclipse environment
>
> Has anyone tried using drools in non-eclipse env ? meaning that
> org.eclipse.jdt.core_3.5.1.v_972_R35x.jar is not in the classpath ?
>
> Documentation says this :
>
> (
http://docs.huihoo.com/drools/4.0.7/ch02s05.html)
>
> if you do not have Eclipse JDT Core in your classpath you must override the
> compiler setting before you instantiate this PackageBuilder, you can either
> do that with a packagebuilder properties file the ChainedProperties class will
> find, or you can do it programmatically as shown below; note this time I use
> properties to inject the value for startup.
>
> They also provide an example, but I am not able to figure out exactly how to
> use this example/info.
>
> Here is my code :
>
> KnowledgeBuilder kbuilder =
> KnowledgeBuilderFactory.newKnowledgeBuilder();
> kbuilder.add(ResourceFactory.newInputStreamResource(is),
> ResourceType.DRL);
>
> where "is" is input stream containing the rule file ( .drl)
>
> How do I override the compiler setting ?
>
> I am getting a null pointer exception ( see below ) and I suspect that
> overriding the packagebuilderconfiguration will fix it ?
