First of all, I did not use Spring MVC. :) :) Just want to get it out first.
Now what I have is different JSP pages that making calls to different Servlets. All the pieces work great individually but I kind of need to link them together. If all of jsp pages make GET
request then it would be easy, since I would just pass a type
via the web address, and on my servlet side, I would just enumerated through all the parameter, determine which type
is it, and delegate to the right servlet. But not all jsp pages make GET
request, some make POST
request via form. Let see example
A.jsp
$.getJSON('GenericServlet?type=A', ...
GenericServlet.java
String type = request.getParameter("type");
if(type.equals("A")){
//Somehow delegate to Servlet A (Not sure how to do that yet :))
}
but in B.jsp
I would have something like this
B.jsp
<form action="GenericServlet" method="post">
<table border=0 cellspacing=10 cellpadding=0>
<tr>
<td>User Name:</td>
<td><input type="text" name="username" size=22/></td>
</tr>
<tr>
<td>Password:</td>
<td><input type="password" name="password" size=22/></td>
</tr>
</table>
<input type="submit" value="Create User" />
</form>
It kind of hard for me to determine in GenericServlet.java
that this need to go to servletB
