Hi All,

While working in my application i came across a situation in which there are likely chances to Unque Constraints Violation.I have following options

Catch the exception and throw it back to UI
At UI check for the exception and show approrpriate Error Message
This is something different idea is to Check in advance about the existance of the given Unique value before starting the whole operation.

My Question is what might be the best practice to handle such situation.Currently we are using combo of Struts2+Spring 3.x+Hibernate 3.x

Thanks in advance
