How to perform date validations in jasper server?

[daad.madhusudan]

I am working on a jasper report which takes two input date parameters from user as START_DATE and END_DATE.

 

I want to put validations on these dates like:

 

1) END_DATE should not be less than START_DATE   

2) START_DATE should not be greater than END_DATE   

3) END_DATE should be max upto 30 days after START_DATE (difference between START_DATE and END_DATE) should be max 30 days

 

 Does anyone know how to to it using ireport? Or is there any alternative way to achieve this in jasper server?

Make use of the Print When Expression property.

 

You could add a Static Text field to the title band of your report that has some like "Start Date must be before End Date". Then set the Print When Expression to be something like $P{START_DATE}.after($P{END_DATE})
