I use something like the following in my struts-config.xml file:
<action path="/signup"
type="SignupAction"
name="signupForm"
scope="session"
input="page1.jsp">
<forward name="page1" path="page1jsp"/>
<forward name="page2" path="page2.jsp"/>
<forward name="page3" path="page3.jsp"/>
<forward name="page4" path="page4.jsp"/>
<forward name="success" path="confirm.jsp"/>
</action>
In page1.jsp I declare the following buttons:
<html:hidden property="page" value="1"/>
<html:submit>
<bean:message key="button.next"/>
</html:submit>
Page2.jsp:
<html:hidden property="page" value="2"/>
<html:submit>
<bean:message key="button.prev"/>
</html:submit>
<html:submit>
<bean:message key="button.next"/>
</html:submit>
Page3.jsp
<html:hidden property="page" value="3"/>
<html:submit>
<bean:message key="button.prev"/>
</html:submit>
<html:submit>
<bean:message key="button.next"/>
</html:submit>
Page4.jsp
<html:hidden property="page" value="4"/>
<html:submit>
<bean:message key="button.prev"/>
</html:submit>
<html:submit>
<bean:message key="button.finish"/>
</html:submit>
In my SignupForm.java I define all fields for each page. Then I have a
switch statement in the validate method to validate the data for each page:
public ActionErrors validate(ActionMapping mapping, HttpServletRequest
request)
{
ActionErrors errors = new ActionErrors();
switch (page)
{
case 1:
// Validate fields on page 1
case 2:
///
}
return errors;
}
Finally in the SignupAction.java I check for which button was pressed and
return the next or previous page:
public ActionForward perform(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException
{
HttpSession session = request.getSession();
SignupForm signupform = (SignupForm) form;
int page = signupform.getPage();
String label = request.getParameter("submit");
if (label != null)
{
if ("<< Prev".equals(label)) // Previous was
pressed
{
return mapping.findForward("page"+(page-1));
}
else if ("Next >>".equals(label)) // Next was pressed
{
return mapping.findForward("page"+(page+1)); //
Finished was pressed
}
else if ("Finish".equals(label))
{
// Do finish work, add data to database, whatever
}
..... return(mapping.findForward("success"));
I'm new to struts (about 2 weeks now). I tried to find examples but couldn't
find any. So I hacked out this. Perhaps if someone has a better way we can
all learn something new.
I hope this helps.
