You are using old API. Which version of drools are you using? <div>You need to do something like:</div><div><br></div><div>KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();<div>kbuilder.add(ResourceFactory.newXXXResource(YYY); , ResourceType.DRL); //replace XXX for the type of resource you want</div>
<div>//add all your resources</div><div><br></div><div>//check for errors</div><div>if (kbuilder.hasEsrrors()){</div><div>...</div><div>}</div><div><br></div><div><div>KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();</div>
<div>kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());</div></div><div><br></div><div>I'm pretty sure all this steps are currently described in the documentation. </div><div><br></div><div>Best Regards,</div>

Hi<br>
I wrote code for creating RuleBase. But I got error at retrieving URL<br>
resource by passing ruleFile to the getResource() method.It is returning<br>
null. How to get the URL resource. I posted the sample code which i have<br>
written for creating RuleBase.<br>
public RuleBase createRuleBase() throws Exception<br>
{<br>
if(rules==null)<br>
{<br>
throw new Exception("No rules provided for Engine");<br>
}<br>
<br>
ruleBase = RuleBaseFactory.newRuleBase();<br>
PackageBuilder builder = new PackageBuilder();<br>
<br>
for(String ruleFile : rules)<br>
{<br>
System.out.println("Rule is "+ruleFile); //prints<br>
the ruleFile<br>
URL resource = this.getClass().getResource(ruleFile); //gets the URL<br>
resource of the ruleFile<br>
<br>
if(resource==null)<br>
{<br>
System.err.println("Could not find resource: "+ruleFile);<br>
continue;<br>
}<br>
<br>
File file = new File(this.getClass().getResource(ruleFile).getPath());<br>
if(!file.exists())<br>
{<br>
System.err.println("Could not find rule file: "+file.getPath());<br>
continue;<br>
}<br>
<br>
builder.addPackageFromDrl(new FileReader(file.getPath()));<br>
}<br>
<br>
org.drools.rule.Package pkg = builder.getPackage();<br>
ruleBase.addPackage(pkg);<br>
<br>
return ruleBase;<br>
}<br>
<br>
My Packages are not adding to RuleBase.It is returning null.<br>
<br>
How to add the packages to ruleBase.Please suggest me<br>
<br>
Thanks<br>
