I have two pages. A and B.
A and B have to import the same package Such as
In page A,
<%@ page import="java.util.Calendar" %>
<%@ page import="java.util.TimeZone" %>
And in page B,
<%@ page import="java.util.TimeZone" %>
============================================
Problem is..
I have to include page B within the page A sometimes
and if I do that, it makes duplication exception.
Right now, my server doesn't throw the duplication exception
but I got the exception from the other server which is not mine.
It look just like this image.
"Only a type can be imported blar blar".
============================================
Is there any way to make sure that the package is imported only one time??
+++++++++++++++++++++++++++++++++
The image is just an example. Point is this sentence; "Only a type can be imported blar blar".
Let me make things clear.
Each pages imports class T with 'page import' directive of jsp.
Page B has a variable of class T.
T inst = new T();
Page A includes page B with 'include' directive of jsp.
I access to the page A, I get this compile error sometimes
Only a type can be imported. java.util.T resolves to a package.
I believe this is caused because I imported the same library in two different pages and I included page B in page A.
Is there any way to solve this without any server configuration??
Create a common file that is shared by each page A and B. You can write your import statements in it and only include it at the top of the main page. Avoid imports from A and B. That way you can make sure imports will not be duplicated. I have used this approach in many projects. In situation like this I envy PHP's require_once / include_once
Hope this will help you.
Enjoy
