<html:errors> in JSP
This is strange, I am working with the DAOS, business object, and struts.
The purpose of this is type a string and click submit, it should be adding a field in test table in mySQL.
The problem is when I click on it, and it'll forward to the success page. I checked the database, it didn't add. I am not getting any error messages in JSP. So, it's really hard for me to debug whatever it is. I made exceptions and properties. I placed the <html:errors/> in the submit page. It stills forward success page, and I didn't see any error messages in success page. I had a small example of getting SQL exceptions in JSP. It was really helpful for me to debug this. So I'm not sure how I can get exception messages from struts. Examples of those will be nice.
A big picture of this is fuzzy in my mind.
-I'm not sure how will the ActionError sends a message to the properties. Then the <html:errors> messages will show up. Here's the files that I'm working on.
AddAction - a struts Action
publicclass AddActionextends Action{
/* forward name="success" path="" */
privatefinalstatic String SUCCESS ="success";
protectedstaticfinal String FAILURE ="failure";
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception{
ActionErrors errors =new ActionErrors();
try{
ClientBO clientBO =new ClientBO();
clientBO.addSheet((SheetsForm)form);
return mapping.findForward(SUCCESS);
}
catch (Throwable e){
e.printStackTrace();
ActionMessage error =new ActionMessage(e.getMessage());
errors.add(ActionErrors.GLOBAL_MESSAGE, error);
}
saveMessages(request,errors);
returnnew ActionForward(mapping.getInput());
}
}
This is a submit page.
