hi,

to add jar files -

1. right click on your project.
2. go to properties.
3. go to java build path.
4. then click on libraries
5. add external jars.

The jar files u will be needing depends upon which functionality u want to use in your project. There is no standard list of jar files as such. Moreover war files are the compressed form of your projects and there is no need to include them to your project. They are used for importing and exporting projects so you need not worry about them.

have you read document for struts ,its well and good

by the way one point i should say you can put your required jar files in web-inf /lib folder so wn you build war ,it automatically added in classpath

if we are using dispatchAction is it necessary to dfine the hidden field in jsp file. or cn i provide namefor the button if i do like tis what happen
