Here is some more details:

· Currently our system loads rules from Guvnor installed on a server (version 5.0.0)

The problem is that there is no way to debug remotely the rules which are already deployed on Guvnor.

So I was wondering “what if I load the rule I need to debug from my local machine instead…. maybe then I’ll be able to debug it…”

· On my local machine I have drools 5.1.0

Here is part of the original code:

--------------------------------

public synchronized void loadRulebasesDefinition() {

ruleBaseList = RulesMapper.getRulesMapper().retrieveAllRuleBases();

for (Entry<Integer, Rule> entry : ruleBaseList.entrySet()) {

                  Rule currentRuleDefinition = entry.getValue();

                  Properties ruleBaseProperties = createRuleBaseProperties(currentRuleDefinition);

                  RuleAgent agent = RuleAgent.newRuleAgent(ruleBaseProperties);

                  currentRuleDefinition.setRuleBase(agent.getRuleBase());

            }

      }

private Properties createRuleBaseProperties(Rule ruleDefinition) {

            Properties properties = new Properties();

            properties.setProperty("url", ruleDefinition.getRuleBaseURL());

            properties.setProperty("poll", Integer.toString(ruleDefinition.getRuleBasePoll()));

return properties;

      }

--------------------------------

The info about the rules is retrieved by the Mapper class from a DB and the result is a map:

Map<Integer, Rule> ruleBaseList

--------------------------------

So I modified the loadRulebasesDefinition() method and I changed the url info in the DB for some of the rules to start with “local:” and to point to a location on my machine:

----------------------------------

public synchronized void loadRulebasesDefinition() {

ruleBaseList = RulesMapper.getRulesMapper().retrieveAllRuleBases();

for (Entry<Integer, Rule> entry : ruleBaseList.entrySet()) {

                  Rule currentRuleDefinition = entry.getValue();

                  Properties ruleBaseProperties = createRuleBaseProperties(currentRuleDefinition);

if (ruleBaseProperties.getProperty("url").startsWith("local:"))

                  {

try {

                             String path = ruleBaseProperties.getProperty("url").replaceAll("local:", "");

                             File file = new File(path);

                             Reader source = new InputStreamReader(new FileInputStream(file));

                             PackageBuilder builder = new PackageBuilder();

                             builder.addPackageFromDrl( source );

                             org.drools.rule.Package pkg = builder.getPackage();

                             RuleBase ruleBase = RuleBaseFactory.newRuleBase();

                             ruleBase.addPackage( pkg );

                             currentRuleDefinition.setRuleBase(ruleBase);

                        } catch (DroolsParserException e) {

                             // TODO Auto-generated catch block

                             e.printStackTrace();

                        } catch (IOException e) {

                             // TODO Auto-generated catch block

                             e.printStackTrace();

                        }

                  }

else

                  {

                        RuleAgent agent = RuleAgent.newRuleAgent(ruleBaseProperties);

                        currentRuleDefinition.setRuleBase(agent.getRuleBase());

                  }

            }

      }

--------------------------------

When I start the project it looks like working,

But when I try to “debug as Drools application” it goes to some point – loads some rules from URLs etc

– and boom:

Exception in thread "main" org.drools.RuntimeDroolsException: [Error: not a statement, or badly formed structure]

[Near : {... Unknown ....}]

Any idea ?

Thanks & Best regards

Which version of drools are you using? 

If you are using a change-set to feed you kagent, then you can use other protocols rather than http to get your rules from: file://, classpath://

Hello,

Is there a way to tell RuleAgent to load rules not only from remote URL ?

i.e. some rules from URL and some rules from LOCAL path on my computer.

(e.g.: c:\some\folder\rule.drl)

Or if it’s not possible exactly that way is there another way to have some rules loaded from URLs and some rules loaded from local path ?

Best Regards

Ivan
