Hi, I've a BRL with Person as a fact containing field name age(in sample package). Now,I've a POJO class named PersonDetails with fields age,name with its getters,setters methods.Now I uploaded that POJO model in that sample package. Now,I need to check in When condition of brl whether age in Person fact is equal to the value obtained from getAge() method of PersonDetails POJO class. When I used guided editor it is giving as age is equal to 1.Literal Value,2.Expression editor,3.Formulae. How can i achieve that ??I should create new instance of PersonDetails p in When condition and i should call p.getAge() and that value must be compared to age in Person Fact. Can you please suggest me how to achieve this.. Thanks -- View this message in context: http://drools.46999.n3.nabble.com/Calling-POJO-class-get-Method-in-BRL-tp...

Thank you Manstis for quick response.I've a small doubt in this Manstis. Actually My Main class PERSON source code is RuleAgent agent = RuleAgent.newRuleAgent("/Guvnor.properties"); RuleBase rb = agent.getRuleBase(); FactType appType = rb.getFactType("details.Personn"); Object application = appType.newInstance(); appType.set(application, "age", 40); rb.newStatelessSession().execute(new Object[] {application}); WorkingMemory wm=rb.newStatefulSession(); wm.fireAllRules(); And my POJO class PersonDetails code is package com.sample; public class PersonDetails { public int age=40; public String name="drools"; public int getAge() { return age; } public void setAge(int age) { this.age = age; } public String getName() { return name; } public void setName(String name) { this.name = name; } } Now my BRL in guvnor is(As per your instructions) rule "brl1" dialect "mvel" 3. | when 4. | PersonDetails( a : age > 0 ) 5. | Personn( age == a ) 6. | then 7. | System.out.println("Welcome Drools"); 8. | end Even it is equal to 40,Im unable to see WELCOME drools message in guvnor 5.3.I uploaded PersonDetails POJO class in that package,it is uploaded and I'm able to see that model in that package,But one error I'm always seeing one message when I'm saving changes in uploaded model.."Unable to save,it was recently updated by guest".Does this error affects my source code of BRL..I didnt get what is the wrong in my BRL. Could you please suggest me what the wrong thing i coded here..Please Thanks -- View this message in context: http://drools.46999.n3.nabble.com/Calling-POJO-class-get-Method-in-BRL-tp...

Hi Manstis, Where do you insert a PersonDetails fact? Why do you set the age on Person when you state it'll be in PersonDetails? You'll also need to have a relationship between Person and PersonDetails and include this in your rule. Manstis,Let me explain my requirement precisely.age is the field in my POJO class which is set to 40.In the same way,I set the value of age which is in Person fact to 40 in my main executable class. Now,I need to compare age in POJO class(which is 40(hardcoded))and age in Person fact(which is set to 40 in the main Java class -appType.set(application, "age", 40);) When these two ages are equal,I should print welcome drools.As both are 40,the output must be Welcome Drools. Here is my BRL code. when 4. | PersonDetails( a : age > 0 ) 5. | Personn( age == a ) 6. | then 7. | System.out.println("Welcome Drools"); 8. | end Should i need to insert Model PersonDetails in the source code?I followed ur instructions to create BRL.Please help me in achieving my requirement -- View this message in context: http://drools.46999.n3.nabble.com/Calling-POJO-class-get-Method-in-BRL-tp...

After your suggestion here is my code, RuleAgent agent = RuleAgent.newRuleAgent("/Guvnor.properties"); RuleBase rb = agent.getRuleBase(); FactType appType = rb.getFactType("personDetailss.Personn"); Object application = appType.newInstance(); appType.set(application, "age", 40); rb.newStatelessSession().execute(new Object[] {application}); WorkingMemory wm=rb.newStatefulSession(); PersonDetails p=new PersonDetails(); wm.insert(p); wm.fireAllRules(); System.out.println(application); MY BRL is rule "myrule1" 2. | dialect "mvel" 3. | when 4. | PersonDetails( a : age > 0 ) 5. | Personn( age == a ) 6. | then 7. | System.out.println("Welcome to drools); 10. | end Even both are 40,Im unable to get output.Please help me -- View this message in context: http://drools.46999.n3.nabble.com/Calling-POJO-class-get-Method-in-BRL-tp...
