Can you write the outputDRL to System.out and check if the generated DRL<br>
syntax is correct ?<br>
<br>
System.out.println(outputDRL);<br>
<br>

I tried to use this also but now I am getting different error:<br>
java.lang.RuntimeException: [8,1]: [ERR 102] Line 8:1 mismatched input<br>
'WHEN'<br>
<br>
<br>
Also, what is the significance of the first line. I have copied it as the<br>
same.<br>
<br>
My code is :<br>
<br>
String curDir = System.getProperty("user.dir");<br>
String fileName =
curDir + "\\src\\com\\rules<br>
\\drools.package";<br>
String
rulePackageContent = FileUtils.readFileToString(new<br>
File<br>
(fileName));<br>
fileName = curDir +
"\\src\\com\\rules\\example.brl";<br>
String brl =
FileUtils.readFileToString(new File(fileName));<br>
BRLPersistence read =
BRXMLPersistence.getInstance();<br>
BRLPersistence write =
BRDRLPersistence.getInstance();<br>
String outputDRL =
rulePackageContent + write.marshal<br>
(read.unmarshal<br>
(brl));<br>
KnowledgeBuilder
builder = KnowledgeBuilderFactory.<br>
newKnowledgeBuilder();<br>
builder.add(ResourceFactory.newReaderResource(new StringReader<br>
(outputDRL)), ResourceType.DRL);<br>
<br>
<br>
if (builder.hasErrors()) {<br>
throw new RuntimeException (builder.getErrors().toString
());<br>
}<br>
KnowledgeBase knowledgeBase =
KnowledgeBaseFactory.newKnowledgeBase();<br>
knowledgeBase.addKnowledgePackages(builder.getKnowledgePackages
());<br>
<br>
I don't know where I am getting this wrong.<br>

I haven't been able to get "ResourceType.BRL" to work. This is how I
do<br>
it ..<br>
<br>
String curDir = System.getProperty("user.dir");<br>
String fileName = curDir + "\\src\\main\\rules\\drools.package";<br>
String rulePackageContent = FileUtils.readFileToString(new File(fileName));<br>
<br>

BRLPersistence read = BRXMLPersistence.getInstance();<br>
BRLPersistence write = BRDRLPersistence.getInstance();<br>
String outputDRL = rulePackageContent + write.marshal(read.unmarshal(brl));<br>
<br>
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();<br>
kbuilder.add(ResourceFactory.newReaderResource(new StringReader<br>
(outputDRL)), ResourceType.DRL);<br>
<br>
<br>
Try this.<br>

Hi,<br>
<br>
I am using Drools-Expert. I am having a class "Person" with data
members as<br>
age and discount.<br>
I am trying to create a .brl. I have these statements in drools.package<br>
package com.rules;<br>
<br>
import com.model.PersonDetails;<br>
<br>
<br>
and in the example.brl I am providing the details of when and then<br>
conditions<br>
<br>
but on execution I am getting the following error :<br>
<br>
java.lang.RuntimeException: [4] Unable to expand: PersonDetails( age <<br>
"20" )[6] Unable to expand:<br>
PersonDetails fact0 = new<br>
PersonDetails<br>
();[7] Unable to expand:<br>
fact0.setDiscount<br>
( 10 );[8] Unable to<br>
expand:<br>
insert(fact0 );<br>
<br>
<br>
It would be helpful is somebody guide me on how execute it.<br>
<br>
Also, I am creating the knowledgebase as:<br>
<br>
private static KnowledgeBase createKnowledgeBase() {<br>
KnowledgeBuilder builder = KnowledgeBuilderFactory.newKnowledgeBuilder();<br>
builder.add (ResourceFactory.newClassPathResource(<br>
"com/rules/example.brl"),ResourceType.BRL);<br>
if (builder.hasErrors()) {<br>
throw new RuntimeException (builder.getErrors().toString
());<br>
}<br>
KnowledgeBase knowledgeBase =
KnowledgeBaseFactory.newKnowledgeBase();<br>
knowledgeBase.addKnowledgePackages(builder.getKnowledgePackages
());<br>
return knowledgeBase;}<br>
<br>
<br>
