at
com.model.Student_College.main(Student_College.java:31)
Now i am sending my main class and .xls
file.
public class Student_College {
public
static void main(String args[]) throws IOException
{
Student s=new Student();
College c=new College();
s.setAge(20);
s.setMarks(35);
c.setRanking("B");
c.setLocation("elhi");
try
{
KnowledgeBase
kbase = readBase();
StatefulKnowledgeSession
ksession = kbase.newStatefulKnowledgeSession();
ksession.insert(s);
ksession.insert(c);
ksession.fireAllRules();
System.out.println("Department
is "+s.getDepartment());
System.out.println("Status
is " + c.getStatus());
ksession.dispose();
}
catch(RuntimeException re)
{
System.out.println("Error
in main ...");
re.printStackTrace();
System.out.println("Error
is "+re);
}
}
private
static KnowledgeBase readBase() throws IOException
{
DecisionTableConfiguration dconf = KnowledgeBuilderFactory.newDecisionTableConfiguration();
dconf.setInputType(DecisionTableInputType.XLS);
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource("manohar.xls",
Student_College.class), ResourceType.DTABLE, dconf);
if(kbuilder.hasErrors())
{
System.out.println("Error
in kbuildefr ......");
throw
new RuntimeException(kbuilder.getErrors().toString());
}
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
return kbase;
}
}
In above main class i used the following
code to interpret my manohar.xls file...
String drlString = null;
try {
drlString
= DecisionTableFactory.loadFromInputStream(ResourceFactory.newClassPathResource("manohar.xls",
Student_College.class).getInputStream(), dconf);
} catch (IOException e) {
// TODO
Auto-generated catch block
System.out.println("Error
in drl String .....");
e.printStackTrace();
}
System.out.println("..........."+drlString);
