Tomcat 4.1.18 jsp import and include error
I installed Tomcat 4.1.18 under Windows 2000 Server and IIS, everything
is fine except two errors:
1. In jsp, when I import a class, this class should in some package,
otherwise you get ClassNotFoundException. But in Tomcat 4.0.4 I can
import a class without package. Is this a Tomcat 4.1.18 feature or bug
?
Example:
with package :
<%@ page import="testPackage.TestData" %>
is ok but without package :
<%@ page import="TestData" %>
you get exception.
2. In jsp, I can only include other jsp pages under that context, and I
can only use relative path, I can not use full url or cross context. I
still can do that in Tomcat 4.0.4, but in Tomcat 4.1.18 I can not.
Example:
if I have a context testContext, under that I have a folder jsp, and a
test.jsp under jsp folder.
use relative path is ok
<%@ include file="/jsp/test.jsp"%>
but can not use full url
<%@ include file="http://myhost:port/testContext/jsp/test.jsp"%>
and can not cross context
<%@ include file="../../otherContext/otherJsp/otherTest.jsp"%>

It's *not* actually a Tomcat issue at all; it's a JDK issue. JDK 1.4.1
enforces the Java Language Specification requirement (discussed below),
whereas JDK 1.3 did not. There is no Tomcat involvement in *any* of this
(other than the fact that it uses the standard reflection capabilities
provided by the JVM).
Bottom line -- the only reason a Tomcat 4.0.6 to 4.1.12 upgrade should
have caused you any grief with unpackaged classes is if you also upgraded
your JDK up to 1.4.1 or later.

Noel,
I think they have clamped down in tomcat 4.1.X all classes now muct be
within packages. This wasn't the case in tomcat 4.0.X or before. When I
changed from 4.0.6 to 4.1.12 I had to formally package all of my beans

Dave

See http://forum.java.sun.com/thread.jsp?forum=31&thread=231550.
You ought to be able to use TestData without an import, since it is in the
default package, but according to the above, you cannot import a class
without a package name because the generated java import statement would be
considered invalid. Mind you that isn't clear from JLS 7.5.1:
