Hi all,
I'm just getting started with jBPM, and I have a small question about XOR gateways. At the moment, our nodes have two endpoints, and the code for one endpoint looks like this:
switch(result) {
case OK:
return true;
default:
return false;
}
While for the other endpoint (pointing to an 'end event'), it looks like this:
switch(result) {
case OK:
return false;
default:
return true;
}
So in the other constraint it's the other way around. To me, this looks like a bit of duplication, and in this example it's not too bad, but in more complex examples, it's trickier. So I was wondering, isn't there a better way to do this? Isn't it possible to create one piece of code, and let true go to one sequence flow, and false to the other, without having the need to duplicate the code? Is something like this possible??
Thanks for the help,
Kind regards,
Erik

Hi All,

[jBPM] - How to use a custom object as process variable

Hi,
I want to use me.bpm.test.Application as a variable for a process. I'm fully using the web based guvnor designer to design the process.
package me.bpm.test
public class Application
{
public String firstName;
public String lastName;
public Date dateOfBirth;
public String address;
public boolean isApproved = false;
public int getAge()
{
int age;
// some code to calculate age using dateOfBirth
return age;
}
}
1. How do I add this class to Guvnor and/or JBPM Console so that in the runtime console can use the class.
2. How do I define the Mapping (assignment, DataInputSet, DataOutputSet) from freeform templates (.flt) to the process level object? Can I use firstName_out->Application.firstName ?
Thanks in Advanced.
