[jboss-user] [JBoss jBPM] - Re: Accessing file that is not in DB from deployed jBPM proc
Hello,
it's me again. My description was a bit imprecise before. The file
'Sample.drl' should actually be deployed in the database. At least I selected the
'Sample.drl' in the Deployment tab of the eclipse plugin together with some java
classes that my process or belonging drools rules need
('FireRulesActionHandler.java' and 'IntValue.java'). Then I deployed the
process and the named files to the server and the "Deployment successful"-Dialog
appeared.
The problem is that when running the process not all of the files are available. The
'FireRulesActionHandler" seems to be there because it is executed just fine but
the 'Sample.drl' and the 'IntValue' class seem to be unavailable. I access
the 'Sample.drl' through a FileInputStream now as a workaround:
| Reader reader = new InputStreamReader(new
FileInputStream("C:/Temp/Sample.drl"));
| but still the 'IntValue' class cannot be found by the JBPM webapp during
execution of the process. The error stack says:
anonymous wrote :
| 20:28:49,176 ERROR [[FacesServlet]] Servlet.service() for servlet FacesServlet threw
exception
| javax.faces.FacesException: Error calling action method of component with id
taskform:transitionButton
| [...]
| Caused by: org.drools.rule.InvalidRulePackage: Unable to resolve ObjectType
'IntValue'
The 'Sample.drl' rule file, which contains the rules that are being fired by the
FireRulesActionHandler, which is called during execution of the process, looks as
follows:
| package com.sample.action
| #package com.sample
|
| import org.jbpm.context.exe.ContextInstance;
| import org.jbpm.taskmgmt.def.Task;
| import org.jbpm.taskmgmt.exe.TaskInstance;
| import org.jbpm.taskmgmt.def.TaskMgmtDefinition;
| import org.jbpm.graph.exe.ProcessInstance;
| import org.jbpm.graph.exe.ExecutionContext;
| import com.sample.action.IntValue;
|
| rule "Check Number"
| when
| ci : ContextInstance()
| IntValue (intVal : value, value > 100)
| then
| ci.setVariable("number", "999");
| System.out.println("Changed number!");
| end
|
And as I said, when testing the whole process including firing rules and everything
through the jbpm API without deploying it and using the web app then it is executing just
fine...
The files should be stored somewhere in the database when they are being deployed right?
But where exactly are they supposed to go?
Does anybody know why this is not working?
Many thanks in advance!
Maurice
