Trigger downstream jobs depending upon the some input parameter

[Arun Kumar]

Hi, 

I have a requirement to trigger a job depending upon the input parameter. 
Lets say i have job J1,j2,J3 and J4 

The J1 executes and depending upon the input parameter x on job J1 it 
should trigger either J2 or J3. If the x is 1 it should trigger J2 and if 
the x is 2 it should trigger J3. 

some what like below flow chart 

                                                    J1 
                                            x=1  /   \  x=2 
                                                  /     \ 
                                                 J2      J3 

Thanks in advance., 
Arun
