garbage collection calls right after “Creating Package Builder …” line in the

heap/memory.</span></font></p>

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

shouted down, but isn't it impossible to compile DRL on Android and the
suggestion is to load pre-serialised KnowledgeBases?<br>
<br>
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?<br>
<br>
Have you looked at <a href="http://blog.athico.com/2011/03/jbpm5-lightweight-running-on-android.html" target="_blank">http://blog.athico.com/2011/03/jbpm5-lightweight-running-on-android.html</a>,
which might give some pointers - although it is only jBPM and not rules
themselves.<br>

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

Subject: Re: [rules-users] Drools in non-eclipse environment<br>
<br>
Which version of drools is this?<br>
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.<br>
