Forwarding from form or action

[Ritu varada]

I have a jsp which accepts input and the action class calls another service class which searches the database and returns a resultset. But, if the resultset is empty, I need to redisplay the input jsp page with an error message. I do not want to call the service method in the form but once I get to action class, how do I go back to input jsp with a message ? I am sorry if this is a really basic question. I am just not sure how to design this. Thanks.

Here is the process:

In your Struts-config.xml, Create a local forward for this action to the input jsp.

In your ApplicationResources.properties file, create an entry for the message you want to display

In your input jsp, place the tag <html:errors/> where you want the message to appear

In your action class, Instantiate an object of type ActionErrors

If the resultSet is empty, instantiate an object of type ActionMessage, using the constructor that requires a message key. (Use the key of the message you set up in the 2nd step above)

Add this object to the ActionErrors using the add() method.

Call the saveErrors() method provided by the superclasss

Forward to the input JSP.
