We are working on a migration project from ASP to J2EE using struts. Because in ASP the complete logic in ASP file itself, so while calling stored procedure to render a report, they are showing 'Loading Data....' message on the screen by temporarily writing the message to the response. This message flushing is followed by a call to Procedure. So till the time the procedure executes, user can see the 'Loading Data...' message.
Now we have to achieve the same functionality. It means once click 'Search' button, we need to call the action class which gives temporary message to the user and followed by calling the Database procedure.
Can any body implemented like this? How to achieve it and is there any other alternatives for it?
