Hello Yamin,
I made a test and got the same error as you pointed.
As far as I understand, the JSP compiler treats crazyClass as a variable but
not as a class. The workaround is to put class into a package.
Consider slightly changed example:
**********************************************************************
WEB-INF\lib
crazyClass.jar
index.jsp
**********************************************************************
<!-- index.jsp -->
<%@page import="test.crazyClass"%>
<HTML>
<BODY>
<H1><%= "Test!" %></h1><%= "at " +
java.util.Calendar.getInstance().getTime() %>
<H2><%= " Line test" %></h2><%= "at " + crazyClass.getValue() %>
</BODY>
</HTML>
**********************************************************************
// test/crazyClass.java
package test;
import java.io.*;
import java.text.*;
import java.util.*;
public class crazyClass
{
public static int x = 0;
public static String getValue()
{
x++;
return Integer.toString(x);
}
}
