Hi All,
I am using drools API, and developed a webservice out of it.
I created rule binary package using BRMS Guvnor.
I used RuleAgent to acces the properties file.
ie RuleAgent agent = RuleAgent.newRuleAgent("/
application.properties");
"application.properties" file was stored in current working directory.
I executed my application using eclipse, it was fine .
For testing purpose i deployed the application in tomcat application
server.
Now it is unable to find "application.properties" file. and shows following
in "catalina.out" file:
java.lang.NullPointerException
at java.util.Properties$LineReader.readLine(Properties.java:418)
at java.util.Properties.load0(Properties.java:337)
at java.util.Properties.load(Properties.java:325)
at org.drools.agent.RuleAgent.loadFromProperties(RuleAgent.java:299)
at org.drools.agent.RuleAgent.newRuleAgent(RuleAgent.java:256)
My question is, in which location should i keep the "application.properties"
file , so that RuleAgent can access it.
Could you please tell me the solution.
Thanks & Regards
Shekhar

Hi,
I had also faced the same problem.
Use the below code, it works proeprly.
Properties properties = new Properties();
InputStream stream = DiscountCheckServlet.class.getResourceAsStream
("<mention your properties file here>");
properties.load(stream);
RuleAgent agent = RuleAgent.newRuleAgent(properties);
Please let me know if it works.

Try putting your .properties file inside "WEB-INF/classes" folder of your

Hi All
Thanks a lot for your kind response.
After putting properties file in the "WEB-INF/classes" it worked.
I will try the method suggested by you too.

Hi All
I am using Guvnor for rule edition and modification.
I uploaded the Package containing the classes for writing rules.
Attributes are taken from the uploaded package.Package was developed in
eclipse editor.
Rule writing was successful. In property file i have stored URL given by the
Guvnor.
I have stored the property file at "WEB-INF/classes".The Rule agent is
reading the property file.
But when I run the project, it shows "ClassNotFoundException" for the class
I uploaded in the Guvnor.
When I viewed the Package source in the Guvnor I could see the import
statement
for the class,but still why this error?
Could anybody give me some hints to solve this.
Thanks & Regards

Hi All,
I am just trying to call the package created in the Guvnor using sample java
class by loading from the properties.
As below :
public static final void main(String[] args) {
System.out.println("Mainnnnnnnnnn");
Properties properties = new Properties();
try {
properties.load(new FileInputStream("Guvnor.properties"));
} catch (IOException e) {
}
RuleAgent agent = RuleAgent.newRuleAgent(properties);
RuleBase ruleBase = agent.getRuleBase();
WorkingMemory workingMemory = ruleBase.newStatefulSession();
GuvnorModel gm=new GuvnorModel();
gm.setAge(22);
workingMemory.insert(gm);
workingMemory.fireAllRules();
for (Iterator i = workingMemory.iterateObjects(); i.hasNext();)
{
System.out.println(i.next().getClass().getCanonicalName());
}
}
//
and got the following error :

@SuppressWarnings("unused")
private final long serialVersionUID=5308493362083281112L;
/**

System.out.println("Mainnnnnnnnnn");
Properties properties = new Properties();
try {
properties.load(new FileInputStream("Guvnor.properties"));
} catch (IOException e) {
}
RuleAgent agent = RuleAgent.newRuleAgent(properties);
System.out.println("Mainnnnnnnnnn1");
RuleBase ruleBase = agent.getRuleBase();
System.out.println("Mainnnnnnnnnn2");
WorkingMemory workingMemory = ruleBase.newStatefulSession();
// Driver d = new Driver("Jarek", 20, null);
GuvnorModel gm=new GuvnorModel();
gm.setAge(22);
workingMemory.insert(gm);
workingMemory.fireAllRules();
for (Iterator i = workingMemory.iterateObjects(); i.hasNext();) {
System.out.println(i.next().getClass().getCanonicalName());
}
}
}//

You need to add that line in org.drools.rule.DialectRuntimeRegistry
and org.drools.base.mvel.MVELCompilationUnit which are drools core classes.
Then you need to recompile Guvnor and Drools again. I suggest you to use the
latest sources to check if the error was solved.
Best,

Hi, I've fixed this bug in the trunk few days ago:
https://jira.jboss.org/browse/BRMS-320
<https://jira.jboss.org/browse/BRMS-320>The bug is still open because I don't
have enough permissions in jira yet. ;)
Please try it out and let me know the results.

Hi All, I am just trying to call the package created in the Guvnor using sample java class
by loading from the properties. As below : public static final void main(String[] args) {
System.out.println("Mainnnnnnnnnn"); Properties properties = new Properties();
try { properties.load(new FileInputStream("Guvnor.properties")); } catch
(IOException e) { } RuleAgent agent = RuleAgent.newRuleAgent(properties); RuleBase
ruleBase = agent.getRuleBase(); WorkingMemory workingMemory =
ruleBase.newStatefulSession(); GuvnorModel gm=new GuvnorModel(); gm.setAge(22);
workingMemory.insert(gm); workingMemory.fireAllRules(); for (Iterator i =
workingMemory.iterateObjects(); i.hasNext();) {
System.out.println(i.next().getClass().getCanonicalName()); } } // and got the following
error : RuleAgent(default) EXCEPTION (Sun Apr 04 15:38:12 EDT 2010):
