Importing Inter-package classes

hello
I have never had this problem before but I just 'downgraded' to JDK 1.1.8 because the code will be used on my PDA. I am trying to import Inter-package classes but the compiler it cannot find the classes I've imported. This code was working perfectly in j2sdk1.4.2_02
I think the code is right all files saved in folder graphs and beginning looks like this:
package graphs;
import graphs.AxisParameter;

Yes they are in the same folder with 'package graphs;' in the 1st line,
i've tried with and without package.class to no avail
the exact errors i'm getting are
without the package in front
error: File .\CustomLabel.class does not contain type CustomLabel as expected, but type graphs.CustomLabel. Please remove the file or make sure it appears in the correct subdirectory of the class path
with the graphs.CustomLabel i get the following errors
error: Invalid class File formate: .\graphs\CustomLabel.class, wrong version: 46, expected 45
2nd error: Class graphs.CustomLabel not found in import.

How to import non-package class in JSP ?

We have develped an enterprise solution in java 1.3 . Some of the controller and controller helper classes donot have any package structure. So they are been kept in web_inf/classes. When any jsp tries to refrence these classes class not found exception arise.
One solution is to put these classes in package and write approprite import statement. But this involve lot of changes. Kindly suggest a solution which can have minimum impact.
I have even jared all these classes into a jar and put that jar in the class path. But still its not working.

It should not be web_inf , the case and the spelling matters it should be WEB-INF , make that correction and see if it works.
If not then, use an IDE to refactor your code.
Some good IDEs with refactoring capabilities are
IntelliJ IDEA - commercial
NetBeans - open source I think (not sure)
Eclipse Web Tools - also open source
Using packages is a good practice, and will make your application more understandable.

Package zzz not found in import (server side classes)

          Hi,
          I'm trying to use the "Web Application" feature in WL 5.10
          (with no service pack). My application contains a couple of
          servlets, a couple of server side classes, and a couple of
          jsp pages.
          I created the WEB-INF\classes directory structure both in
          public_html and in my application's root directory. I
          modified setEnv.bat to contain the two directories in
          ClassPath and compilation of my servlets from the command
          line completes OK (the servlets import a package that sits in
          public_html\WEB-INF\classes).
          However, when I try to import the same package from a jsp
          file, I get the "package zzz not found in import" error
          message. The trace shows that the java compiler invoked
          after the servlet has been generated does not contain
          public_html\WEB-INF\classes in the ClassPath, but contains
          public_html\my_app\WEB-INF\classes.
          How can I specify that the java compiler should look under
          public_html\WEB-INF\classes for server side classes? Is there
          another solution and am I even using the right approach?
          Thanks,
          Vladimir

          You should install the service packs, your problem will probably
          disappear then.
          Web Apps are better supported with service packs.

It means you didn't deploy the servlet properly.
Put the package back - all your Java classes should go into packages. All the time. The only exception is when you're writing a quick knock-off to test something that you'll run on the command line and rarely use again.
No surprise - the code you've written is certainly terrible. HTML to the output stream - ever heard of JSP?
SQL code in a servlet - ever hear of Data Access Objects?
Layering apps makes them easier to test, debug, maintain, and understand.
What servlet/JSP engine are you using? Tomcat? If so, Tomcat requires that you use packages.
Where did you put this beauty of a servlet? Better not be /ROOT. Create a directory under /webapps for your app and deploy it there.
What URL did you use to invoke the servlet? I'll bet that's wrong, too.
Lots to correct here.

How to import a package in jsp

i've searching here and i've not found answer to this, so i write it here.
i've created a class to send mail, it imports the javax.mail.* and javax.activation.*, in a package named jspbeans.
now, when i try to use this package in my jsp page (using tomcat), gives me the error:
Package jspbeans not found in import
import jspbeans.*;
the code for my jsp page is:
<%@ page language="java" %>
<html>
<head>
<title>Sending mail from JSP</title>
</head>
<body>
<%@ page import="jspbeans.*"%>
<jsp:usebean id="sendmail" class="jspbeans.SendMail" scope="page"/>
<jsp:setProperty name="sendmail" property="host" value="mail.wavelinksystems.com"/>
<jsp:setProperty name="sendmail" property="to" value="[email protected]"/>
<jsp:setProperty name="sendmail" property="from" value="[email protected]"/>
<jsp:setProperty name="sendmail" property="msg" value="testing 1 2 3..."/>
<jsp:setProperty name="sendmail" property="subject" value="test"/>
<%//sendmail.send();%>
<p>
Mail has been sent to <jsp:getProperty name="sendmail" property="to"/>
</body>
</html>and the path of this jsp page is:
C:\WINDOWS\Desktop\tomcat\jakarta-tomcat-3.3.1\webapps\ROOT\pruebas\jspMailTest.jsp
the path for the package is:
C:\WINDOWS\Desktop\tomcat\jakarta-tomcat-3.3.1\webapps\ROOT\pruebas\jspbeans
what am i doing wrong?
what am i missing?
how do i have to import the package?
thanks

it generates a
java.lang.NoClassDefFoundError: javax/mail/MessagingException
i changed the package to that directory and the import generates no errors, if i do nothing but the import, and soem printing, the page is generated, but when i try to assign the variables, generates that error, why is it?

Problem with importing jsp packages

Hi guys. I'm having a problem compiling a class that imports jsp packages.
I'm getting errors along the lines of:
C:\>javac HelloTag.java
HelloTag.java:4: package javax.servlet.jsp does not exist
import javax.servlet.jsp.*;
^
HelloTag.java:5: package javax.servlet.jsp.tagext does not exist
import javax.servlet.jsp.tagext.*;
- I've copied jsp-api.jar and servlet-api.jar to a folder that's in my path: C:\Program Files\Java\jre1.5.0_03\lib\ext
Any suggestion?
Thanks.

U have to add the path into the classpath
set CLASSPATH=%CLASSPATH%;jsp-api.jar ....
the compile in the same cmd window
Do not use the CLASSPATH environment variable. Use the -classpath option while compiling and specify the path to your jar file.
javac -classpath <path to jar file> filename.javacheers,
ram.

HELP: Import my own class in JSP ???

Hi, all!
I read many previous topics in this forum but no one works for me!
Please someone help me!
I'm using Tomcat 4.1.12 and my JSP scripts work just fine, but I need to import my own .class file. I just don't know where to put it so Tomcat can find it!?
I have this environment variable:
JAVA_HOME=.;c:\jdk1.3.1
And in my code I'want to place something like this:
<%@ page import="myClass" %>
But I get a "can not resolve symbol" exception.
Thanks for readind this, and please help if you can!
Bye.
adriano

Within the Tomcat directory, under your application directory place the class file/s into the WEB-INF/classes directory. If your classes are part of a package place the entire directory structure of the package under the WEB-INF/classes directory.
The import in the JSP is the same as for any Java class.
Hope this solves your problem.

Importing my own classes

I have 2 simple classes in the same directory and I'd like to test the use of import to import one class into the other. Upon compilation of the class thats doing the import, I get a compilation error. Herewith the details, where could I be getting it wrong.
****code for class to be imported****
import java.util.Date;
public class printer
public void print()
System.out.println(new Date());
System.out.println("Hello World");
--The above code compiles with no problems.
***Code for the main class that imports the above*****
import printer;
public class myapp
public static void main(String[] args)
(new printer()).print();
-upon compiling the second class above, myapp.java, I get the following errors:
C:\java\source>javac myapp.java
myapp.java:1: '.' expected
import printer;
^
myapp.java:1: ';' expected
import printer;
^
2 errors

Moreover, classes do not need to import any class which is in the same package as their own, and since your printer class is in the default package (if you call that a package) you shouldn't need to import it into myapp anyway

How to import GreenSock external classes?

Hi, I'm having some problems in importing GreenSock external classes into my flash project.
Line 27: import gs.*;
Desktop\myFlashAPPS\twitter\src\zainu\twitter\MainClass.as, Line 27
1172: Definition gs could not be found.
Here is the directory tree:
myFlashApp (contains myproject.fla)
     src
          zainu
               twitter (contains MainClass.as and gs folder)
MainClass.as:
package zainu.twitter{

You could try specifying the path to the gs folder as if you were importing it directly from the myproject.fla file.
You should set up a classpath for external classes for your system so that Flash has a ready reference for finding them. YOu can set this up via using Edit -> Preferences... -> Actionscript -> Actionscript 3.0 Settings... -> specify a source path. Normally what people do is create a folder in a relatively general location and use that as their source path.   Within that they place a "com" folder, and within that com folder they place their subfolders for different classes they acquire from outside sources, such as your gs folder. So when you want to import the gs classes you can use... import com.gs.*;
There is a tutorial at gotoandlearn that explains this...   http://www.gotoandlearn.com/play.php?id=30

Importing a Custom Class

Hi everyone...
I'm working on one final part of a Flash piece that's ended being quite a bear for me. So looking forward to wrapping it up! I'm a big-time newbie. This has been an amazing learning experience but boy it has made my brain hurt!
The final issue I'm having invloves importing a custom class that calls a custom application. It's a class/application that I downloaded and am trying to apply to my project. It is an application that adds transform handles around targeted objects.
I'm importing the class as I think I am supposed to but it doesn't work. There aren't any erros but it simply doesn't work.
Here's how I'm doing it...
My .FLA, FloorPlan.FLA, is located in my root folder along with the class file, ApplicationMain.as.
ApplicationMain.as has an import that imports the application called TransformTool.as. TransformTool.as is located in the root as well.
So in scenen 1 on frame 1 of FloorPlan.FLA I have an import written like so...
import ApplicationMain;
In the file ApplicationMain.as I have an import to grab the file TransformTool.as that is written like so...
package {
    import flash.display.MovieClip;
    import flash.geom.Rectangle;
    import flash.events.MouseEvent;
    import TransformTool;
    public class ApplicationMain extends MovieClip
        private var _transformTool;
        public function ApplicationMain ()
            _transformTool = new TransformTool();
            _transformTool.mode = TransformTool.ROTATE;
            _transformTool.iconScale = new HandleHintScale();
            _transformTool.iconRotate = new HandleHintRotate();
            // _transformTool.boundaries = new Rectangle(50, 50, 475, 260);
            addChild(_transformTool);
        // register targets //
            _transformTool.targets = [content_MC.e1, content_MC.e2, content_MC.e3, content_MC.e4, content_MC.f1, content_MC.f2, content_MC.f3, content_MC.f4, content_MC.f5, content_MC.f6, content_MC.f7, content_MC.f8];
            _transformTool.activeTarget = content_MC.f8;
        // register radio buttons //
              // radio1.addEventListener(MouseEvent.CLICK, changeToolMode);
          // radio2.addEventListener(MouseEvent.CLICK, changeToolMode);
        private function changeToolMode(evt:MouseEvent):void
            _transformTool.mode = evt.currentTarget.label.toLowerCase();
Everything but this class/application is working just fine. It doesn't cause any erros and make other items not function. It simply isn't working. And I had it working at the very beginning of the project so I know its not the class/application files causing the problem; other than possible path issues.
I'm stumped, yet again!
Thanks in advance for your help!

Not able to access default package classes in own package

I created a class called Constant.java in default package(no package ).
I have Connection.java in util package.
I am trying to use the Constant.java in my Connection.java like below..
public class Constant
public static final String NEW = "01";
package util;
import Constant;
public class Connection
I am unable to compile the class Connection. My question here is Won't I able to access default package in my util package.. ?

Djaunl , I understand.
but, Will I able to access default package in my util package.. ? is this correct.No, you won't be able to use classes out of the "default" package.
Because, AFAIK, if you use a classname that you haven't imported, Java automatically attempts to locate this class in the same package as the current class. It does not check the "default" package (unless that is also the current package), and since the "default" package does not have a package name, you can't import those classes either.

Import and package does not exist

I have a program and I wish to import a package that I've made. I have tried to do this with:
import clientcode.*;but I keep getting the error message java:8: package clientcode does not exist
I am completely new to Java and have no idea how to get around this. Please help

Do you use ide or compile classes from command line?
Most likely it's a classpath problem.

Compiling java package class referring a default package class.

I am trying to compile a java class having a package defination referring a java class with a default package.
The code for the default package class is .
public class Test{.
public static void main(String[] args){
System.out.println("Hello World!");
This class compiles fine.
I have another class called PackJava, whose code is :
package test;
import Test;
public class PackJava{
public static void main(String[] args){
Test test = new Test();
System.out.println("Hello World!");
I have Test file in the windows path
D:\development\packagetest\example
and the PackJava java file in the path
D:\development\packagetest\example\test
I have set the CLASSPATH environment varibale as
D:\development\packagetest\example;.
When I try to compile the PackJava from the
D:\development\packagetest\example path giving the command as
javac -classpath . test\PackJava.java
or
javac -classpath %CLASSPATH% test\PackJava.java
it gives me error,
Do any of you have an idea of the parameter i should pass
to the -classpath option
Thanks

There is a way around all this. The classes in the default packages need to implement an interface with the methods require. The interface can be in any package you want ie. com.work.around.interf.MyInterface1. Next, make this interface available in a Singleton. - The only catch here is that, the main method must reside in default package as well. And o, on start of main, instantiate the class you want and put it in the singleton. There after, you may refer to it from the singleton.
Enjoy.
