Following is my code:
KnowledgeBuilderConfiguration kbc =
KnowledgeBuilderFactory.newKnowledgeBuilderConfiguration();
kbc.setProperty("drools.dialect.java.compiler", "JANINO");
KnowledgeBuilder builder = null;
builder = KnowledgeBuilderFactory.newKnowledgeBuilder(kbc);
Reader drlSource = new
InputStreamReader(RVEngine.class.getResourceAsStream(ruleset.getDrlSourc
e())); //ruleset.getDrlSource() = com/cit/myDrl.dslr
Reader dslSource = new
InputStreamReader(RVEngine.class.getResourceAsStream(ruleset.getDslSourc
e()));
builder.add(ResourceFactory.newReaderResource(dslSource),
ResourceType.DSL);
builder.add(ResourceFactory.newReaderResource(drlSource),
ResourceType.DSLR);
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(builder.getKnowledgePackages());
no matter what I type in my dslr (drl) file I get the following
exception on the highlighted line; ANY IDEA????
I have 1 rule or No rule it still throws the same exception. Does it
have to do with any jar files?

It could be an error in the DSL file. Check for errors after *each*
builder.add(...).

New subject: HELP - Problem creating package -validateUniqueRuleNames(PackageBuilder.java:830)
All my rules worked fine with Drools 3. NowI am trying to upgrade to
Drools 5.
I am using the following jar files to create binary (jar) files for my
rules from command line:
antlr-runtime.jar, drools-api.jar, drools-compiler.jar, drools-core.jar,
drools-decisiontables.jar, drools-jsr94.jar, drools-templates.jar,
janino-2.5.15.jar, joda-time.jar, jsr94.jar, jxl.jar, mvel2.jar,
xpp3.jar, xpp3_min.jar, xstream.jar,
org.eclipse.jdt.core_3.6.1.v_A68_R36x.jar
This is my DSLR:
package cit.coverage;
expander Coverage.dsl
rule "rrr"
auto-focus true
when
He is nice
then
He is happy
end
This is my DSL Coverage.dsl:
[condition][]He is nice=eval(true)
[consequence][]He is happy=eval(System.out.println("HA HA"))
I am trying to create binary(jars) using the following code:
KnowledgeBuilderConfiguration kbc =
KnowledgeBuilderFactory.newKnowledgeBuilderConfiguration();
kbc.setProperty("drools.dialect.java.compiler", "JANINO");
KnowledgeBuilder builder = null;
builder = KnowledgeBuilderFactory.newKnowledgeBuilder(kbc);
Reader drlSource = new
InputStreamReader(RVEngine.class.getResourceAsStream(ruleset.getDrlSourc
e()));
//ruleset.getDrlSource() = com/cit/myDrl.dslr
Reader dslSource = new
InputStreamReader(RVEngine.class.getResourceAsStream(ruleset.getDslSourc
e()));
builder.add(ResourceFactory.newReaderResource(dslSource),
ResourceType.DSL);
builder.add(ResourceFactory.newReaderResource(drlSource),
ResourceType.DSLR); <-- problem
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(builder.getKnowledgePackages());
no matter what I type in my dslr (drl) file I get the following
exception on the highlighted line;
I have 1 rule or 0 rule it still throws the same exception. Does it have

This is my DSLR:
package cit.coverage;
expander Coverage.dsl
rule "rrr"
auto-focus true
when

then
He is happy
end
*This is my DSL** Coverage.dsl**:*
[condition][]He is nice=eval(true)
[consequence][]He is happy=eval(System.out.println("HA HA"))
This is not a correct Java statement, as it should be for the consequence:
- eval() is not valid here
- There is no semicolon at the end
This would be correct:
[consequence][]He is happy=System.out.println("HA HA");
The NPE should be gone in 5.2.0.

Sorry .. no use. I made those changes but nothing different. I'll try
