I'm also an newbie to using struts. Here's my work in use.


Platform: Jrun4.0 + struts.

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
 
public class UserContactBatchUploadAction extends Action
{
    
    private static Log log = LogFactory.getLog(UserContactBatchUploadAction.class);
 
    public ActionForward execute(ActionMapping mapping, ActionForm form,
                                 HttpServletRequest request,
                                 HttpServletResponse response) throws Exception
    {
      
        String custId = request.getParameter("custId");
 
        try
        {
            log.info("custId = " +custId);
            .
            .
 
        } catch (Exception e)
        {
            log.info("Exception", e);
            ActionMessages messages = getMessages(request);
            messages.add(ActionMessages.GLOBAL_MESSAGE, new ActionMessage(
                    "error.default.exception", e.getMessage()));
            saveMessages(request, messages);
        } finally
        {
        }
    }
}

web.xml

  <servlet>
    <servlet-name>action</servlet-name>
