hi all
i get the following exception

javax.servlet.ServletException: Cannot find message resources under key org.apache.struts.action.MESSAGE

here's what i wrote im my ActionForm class

i suppose i must create a file and map "error.param.notValid" to a message string or something ..

how can i display my error message in a jsp if say the param in the ActionForm class is empty??


thanx

Hi,

You have to create an application resource file in the src folder with your java code.

For example, you can call it Application.properties.

In this file, put :



In your struts-config:

>

In your jsp :



And in your ActionForm class :



In Struts-config.xml, don't forget to code :



And normally messageparam is required. will be displayed.

I hope it helps you.
