10 points if you can solve this for me. Thanks.

Your applet java code is fine: try this
<html>
<applet code = "HelloWorld.class" width = "200" height = "100">
</applet>
</html>
(you didn't close the applet tag </applet> and you don't need the other cr@p)

Loading a simple Hello World Applet faster?

I'm new to java. I;m trying to load the hello world applet but the problem is that it takes about 20 to 30 seconds to load at first attempt, I there a way to make this faster, i have tryed making a jar file and running that but nothing changes in speed.

Well, it's always going to be slower to run the applet in a web page in a browser because you have the extra steps of the browser grabbing the files over the network, parsing the HTML fully, displaying the page, and starting the JVM. The appletviewer grabs the files locally, does a simpler parse of the HTML, doesn't have to display much HTML, and already is a JVM.
In my experience, JVMs inside of browsers (the early days) were significantly slower than a JVM you invoked on the command line. Now that there's the plug-in, it's still slower but not by much.
What browser are you using? Are you using a modern browser and the Java plug-in or are you using, say, and old browser with the JVM built in?
Also, how long does it take to download the HTML and the class file from the server? What happens when you download them directly with something like wget or curl?

No. Post the question in an Eclipse forum.

Basic (and I mean basic) java problem with a simple hello world script

I have a simple cut-and-paste html page and java class in my /home/jc158027/java directory.
jc158027> cat HelloWorld.java
import java.applet.*;
import java.awt.*;
public class HelloWorld extends Applet{
Label helloLabel = new Label ("Hello World");
public void init () {
setBackground (Color.yellow);
add (helloLabel);
}Ok, so I javac HelloWorld.java and get HelloWorld.class, so far so good.
Next I create my html page:
jc158027> cat hw.html
<HTML>
<HEAD>
<TITLE>Jay's Java Test Page</TITLE>
<BODY>
<HR>
This line of text comes before the applet.
<APPLET CODE = 'HelloWorld.class" WIDTH=500 Height=90>
</APPLET>

This line of text comes after the applet.
</BODY>
</HTML>The result is that the text lines work, I get a nice grey box with no applet running. Looking at my console I get the following error:
Caused by: java.io.FileNotFoundException: /home/jc158027/java/HelloWorld/class".class (No such file or directory)
What I don't understand is the HelloWorld/class".class portion, shouldn't it be just either HelloWorld".class or HelloWorld/class, it is as though it is trying to look in a directory (class) that does not exist.
What am I missing here?

And if you put dots in where it expects a class name, it assumes those dots are to separate levels in a package name.
So it was looking for a class named "class", which would be in a file called class.class, in a package named "HelloWorld". Packages correspond to directories relative to some classpath root, so it looked for the directory HelloWorld to be the parent of the classes in the HelloWorld package.

Hello, World Applet

Plz Plz help me, im really new to Java and im trying to create a hello wolrd applet, this is the following code im usuing:
class helloWorld

Plz help me, i would really like to expand my knowledge in Java.

im having trouble again with the applet.Are you sure it's an applet? If so, applets are not designed to be run as standalone applications (no main method)...
i really dont get wot this means, plz help me.
java -cp . helloworld.AppYou get a NoClassDefFoundError message because the JVM (Java Virtual Machine) can't find your class. The way to remedy this is to ensure that your class is included in the classpath. The example assumes that App.java contains the "package helloworld;" statement, you have correctly compiled App.java (class names and their corresponding source files should be capitalized), and are running the command from the directory that contains the path helloword/App.class.

Exception in thread "main" java.lang.NoClassDefFoundError: hello
Does anyone know what could be the cause of this error?
Thanks in Advance!!

Please check your class path. Make sure that current working directory is included in it.
If not add it as shown below

Simple "Hello world" servlet in sap j2ee 6.20

Hello @ all,
I want to develop a little "hello world" servlet which runs on a sap j2ee 6.20.
Writing the code is not the problem
But I do not know which steps I have to do in order to get the servlet to run.
Do I have to create an ear-File? If yes how can I build an ear-File!
Or is the a way to just create a folder in the root of the j2ee with an WEB-INF folder! I tried this but it dosn´t work!
Is there perhaps a plugin available for eclipse 2.1 to develop and deploy the application to the sap j2ee??
Thanks alot for your help!
Best regards
Kai

Hi Kai.
Coding is always cool!! Never a problem
>>Do I have to create an ear-File? If yes how can I build an ear-File!
Anyways, If you have created the J2EE application then you have to build a Web Applicatipn Project. And then give the reference of your application to this Web Application Project. Now craete a archive file of this web application project.
When you will do this a .ear file will be created and a .war file will also be created in your application. Noe Deploy ear to J2ee engine. It will ask for the password of SDM. Give that password and it will be deployed on the SAP J2ee engine.
To run the application write:
http://<my_server>:<my_port>/irj/servlet/<my_application_name>/
This will run your application. Hope this will help.
Do award points if you find answer is helpful for you.

Problem with a simple hello world JSP

We have just installed WLS Express 7.0 (just downloaded) on a Solaris 8 server. Using the dmwiz.sh, we have created a new domain with a managed server. Both the Admin Server and managed server have started and are running. When I tried to load a sample web application (a war file that has a hello world JSP), I got a HTTP 500 internal server error in serving the hello.jsp page. This sample works fine in Windows WLS Express 7.0.
Can someone please help? Thank you in advance.

Problem running a simple Hello World RMI Program

I wrote a simple RMI application, consisting of a Server Interface, Server Implementation and a Client.
Since the codes are really small, am pasting them here so that you could identify the problem if any, in the code.
1. Server Interface......
import java.rmi.* ;
public interface HelloInterface extends java.rmi.Remote
     public void sayHello(String arg) throws RemoteException ;
2. Server Implementation......
import java.rmi.* ;
import java.rmi.server.* ;
public class HelloImpl extends UnicastRemoteObject implements HelloInterface
     public HelloImpl() throws RemoteException
          super() ;
     public void sayHello(String arg) throws RemoteException{
          try{
               System.out.println("RMI Program : Hello "+arg) ;
          catch(Exception e){
               e.printStackTrace() ;
               //throw new java.rmi.UnexpectedException("undeclared checked exception", e);
     public static void main(String[] args) throws RemoteException
          try{
               if( System.getSecurityManager() == null )
                    System.setSecurityManager( new RMISecurityManager() ) ;
               HelloImpl impl = new HelloImpl() ;
               Naming.bind("HelloService",impl) ;
               System.out.println( "Service bound..." ) ;
          catch(Exception e){
               e.printStackTrace() ;
               //throw new java.rmi.UnexpectedException("undeclared checked exception", e);
3. Client Code.
import java.rmi.* ;
import java.rmi.Naming.* ;
class RMIClient
     public static void main(String[] args)
          try{
               if(System.getSecurityManager()==null)
                    System.setSecurityManager( new RMISecurityManager() ) ;
               HelloInterface helloInt = (HelloInterface) Naming.lookup("rmi://sand.cise.ufl.edu/HelloService") ;
               helloInt.sayHello("Ranjit") ;
          catch(Exception e){
               e.printStackTrace() ;
I have double checked the classpaths and they all look fine..
I have even unset the classpath from the shell which runs the rmiregistry..am still getting these errors..
1. If i use the default java to run the application..this is the error that it spits..
sand:24% java -Djava.security.policy=java.policy HelloImpl
java.rmi.UnexpectedException: undeclared checked exception; nested exception is:
java.lang.ClassNotFoundException: HelloImpl_Stub

2. Using java from some other location..the error looks different...but in both cases it just gives errors :((

I am embarking on a huge assignment but if am having problems getting started..
Your help will be highly appreciated..
thanx and regards
Ranjit Iyer

First of all you should be posting this Q in the RMI forum :)
You are getting that error because your stub is not in your clients classpath (or u can say the compiler is not able to find it).
Make sure that the file HelloImpl_Stub is in the client classpath/package.

I tried the following workarounds but not much of help:
1) Tested the database connection in my jdeveloper which showed sucess !!
2) In the run time connect dialog box, I have used FND as application short name and APPLICATION_DEVELOPER as responsibility key
3) I reviwed all the steps in the document
4) I checked if the DBC file is the correct one.
It would be great if anyone of you can suggest some options or if the issue resolution. I am still doing research on this.

How to make a simple hello world c program in xcode???

Hello..... I've learnt the basics of c programming recently, They use code blocks (ver 10.05) in my class. Im new to Xcode.. so please can you help me?

Go to http://www.netbeans.org/
You should find tutorials there.

If the "Hello World" Applet were two classes....

...okay, so I'm oversimplifying. I've written a pretty useful little applet that is now well in excess of 2000 lines - but I've fallen back to my roots as a C programmer to make the thing work as a single class since every attempt I've made to get multiple classes to work on my little web app has failed.
I've tried something (roughly) like this:
======s1.java
package stuff;
class s1 extends Applet
        s2 foo;
        public void init()
                foo = new s2();
======s2.java
package stuff;
class s2
        init()
                int foo = 0/0; (I know it runs if I get exception)
}Now, I jar this up and it attempts to load, but doesn't find s2. Is there
a set of requirements regarding the naming of the package, the naming of
the jar file, etc.? I know I'm missing an import line in s1.java.... what
should that import line read to be able to see s2?
(The .html does load the jar, but throws an exception trying to find the
s2 class.)

Even in c you have to import, though you should not have to do so if you truly have them in the same package (same project same folder). Are you using an IDE?

Setting up TomCat on Vista for simple hello world sampl (usingxWire maybe)

Re-entering Java after many years working with c#/vb.net only.
Does anyone have any links for a newbie setting up/configuring a machine to get me started.
Thank you!
hazz

Thank you Martin!
I was about ready to download Eclipse.
I see 3 versions; With TomCat being a J2EE web server do I get 2 below?
1. Eclipse IDE for Java Developers
2. Eclipse IDE for Java EE Developers
3. Eclipse Classic 3.3.2
Thank you,
Greg

HOW TO: Create a GUI "Hello World"


This document describes how to create and run a very simple "Hello World"
Java GUI app using JDeveloper. The application will have one button and one
text field. Clicking the button will populate the text field with the message,
"Hello World!"
Creating The New Application
In this section, we will create an application with an empty frame.
<ol>
[*]Choose File | New Workspace.
</li>
[*]Choose File | Save Workspace.
</li>
[*]Enter <TT>HelloGui.jws</tt> as the name for the workspace.
This creates a Workspace called HelloGui. A workspace organizes all the projects
you need to work on at one time.
</li>
[*]Choose File | New Project.
The Project Wizard opens. This wizard will help you create a new project called
HelloGui. A project contains all the files that go together in one "tier"--for
example, all the files belonging to a single Java Application client, or all
the files belonging to an Enterprise Java Bean. Because we are working on
a simple, one-tier application, we will only need one project in our workspace.
</li>
[*]If the Welcome page appears, click Next.
</li>
[*]On the Project Type page, in the What is the Project's Filename?
field, change the filename to <TT>HelloGui.jpr</tt>. Leave the rest of the
path the same.
</li>
[*]Select A Project containing a new... and choose Application
from the dropdown list.
</li>
[*]Click Next.
</li>
[*]On the Project Options page, in the What is the name of the project's
default package field, enter <TT>helloGui</tt>.
</li>
[*]Click Next.
</li>
[*]On the Project Information page, you can enter any information about your
project that you wish.
</li>
[*]Click Finish.
The Application Wizard opens.
</li>
[*]In the Class field, enter <TT>HelloApp</tt>.
</li>
[*]Select the New Empty Frame radio button.
</li>
[*]Click OK.
The Frame Wizard opens.
</li>
[*]In the Class field, enter <TT>HelloFrame</tt>.
</li>
[*]Click OK.
JDeveloper creates an application, <TT>HelloApp</tt>, containing an empty
frame, <TT>HelloFrame</tt>. The source code for these classes appears in the
Navigator, which is the upper left-hand pane in the JDeveloper IDE.
</li>
[*]Choose File | Save All.</li>
</ol>
Adding a Panel to the Frame
In this section, we will now add a panel to the frame. In the next section,
we will add all the other components to this panel.
<ol>
[*]In the Navigator, double-click <TT>HelloFrame.java</tt>.
A viewer opens. This viewer has four tabs at the bottom:
<ul>
[*]Source, the currently active tab, which displays the source code
of the selected class</li>
[*]Design, which invokes a visual layout designer</li>
[*]Class, which invokes an editor for the class' attributes, and
can help you stay JavaBean complient</li>
[*]Doc, which displays the class' JavaDoc
</li>
</ul>
</li>
[*]Click the Design tab.
The viewer now displays a grey square, a graphical mock-up of your frame.
Also, on the right-hand side of your screen, the Property Inspector opens.
This allows you to quickly set attributes and define events for components.
</li>
[*]In the component palette (the tabbed toolbar near the top of your screen),
select the Swing Containers tab.
</li>
[*]Click the blue square (described in rollover text as <TT>JPanel</tt>) and
click on your frame to add the panel.
The Property Inspector now displays attributes of the JPanel.
</li>
[*]In the Property Inspector, click twice inside the box beside the name
field.
</li>
[*]Change the name to mainPanel.
</li>
[*]Click the box beside the layout field.
</li>
[*]Choose XYLayout.
XYLayout is an easy-to-use Layout for prototyping. Later, we will change the
layout to a more portable one.</li>
</ol>
Adding Components to the Panel
In this section, we finish laying out a prototype UI. We will add polish and
portability to the UI later.
<ol>
[*]In the Component Palette, select the Swing tab.
</li>
[*]Select the <TT>JTextField</tt> component, which looks like a text field
with a cursor.

Hello,
I followed your instruction step by step to make this "Hello World", but when I run it, I got message "cannot find the runable node". What do I miss here? Thanks.
<BLOCKQUOTE>quote:<HR>Originally posted by Avrom Faderman ([email protected]):

This document describes how to create and run a very simple "Hello World"
Java GUI app using JDeveloper. The application will have one button and one
text field. Clicking the button will populate the text field with the message,
"Hello World!"
[b]Creating The New Application
In this section, we will create an application with an empty frame.
<ol>
[*]Choose File | New Workspace.
</li>
[*]Choose File | Save Workspace.
</li>
[*]Enter <TT>HelloGui.jws</tt> as the name for the workspace.
This creates a Workspace called HelloGui. A workspace organizes all the projects
you need to work on at one time.
</li>
[*]Choose File | New Project.
The Project Wizard opens. This wizard will help you create a new project called
HelloGui. A project contains all the files that go together in one "tier"--for
example, all the files belonging to a single Java Application client, or all
the files belonging to an Enterprise Java Bean. Because we are working on
a simple, one-tier application, we will only need one project in our workspace.
</li>
[*]If the Welcome page appears, click Next.
</li>
[*]On the Project Type page, in the What is the Project's Filename?
field, change the filename to <TT>HelloGui.jpr</tt>. Leave the rest of the
path the same.
</li>
[*]Select A Project containing a new... and choose Application
from the dropdown list.
</li>
[*]Click Next.
</li>
[*]On the Project Options page, in the What is the name of the project's
default package field, enter <TT>helloGui</tt>.
</li>
[*]Click Next.
</li>
[*]On the Project Information page, you can enter any information about your
project that you wish.
</li>
[*]Click Finish.
The Application Wizard opens.
</li>
[*]In the Class field, enter <TT>HelloApp</tt>.
</li>
[*]Select the New Empty Frame radio button.
</li>
[*]Click OK.
The Frame Wizard opens.
</li>
[*]In the Class field, enter <TT>HelloFrame</tt>.
</li>
[*]Click OK.
JDeveloper creates an application, <TT>HelloApp</tt>, containing an empty
frame, <TT>HelloFrame</tt>. The source code for these classes appears in the
Navigator, which is the upper left-hand pane in the JDeveloper IDE.
</li>
[*]Choose File | Save All.</li>
</ol>
Adding a Panel to the Frame
In this section, we will now add a panel to the frame. In the next section,
we will add all the other components to this panel.
<ol>
[*]In the Navigator, double-click <TT>HelloFrame.java</tt>.
A viewer opens. This viewer has four tabs at the bottom:
<ul>
[*]Source, the currently active tab, which displays the source code
of the selected class</li>
[*]Design, which invokes a visual layout designer</li>
[*]Class, which invokes an editor for the class' attributes, and
can help you stay JavaBean complient</li>
[*]Doc, which displays the class' JavaDoc
</li>
</ul>
</li>
[*]Click the Design tab.
The viewer now displays a grey square, a graphical mock-up of your frame.
Also, on the right-hand side of your screen, the Property Inspector opens.
This allows you to quickly set attributes and define events for components.
</li>
[*]In the component palette (the tabbed toolbar near the top of your screen),
select the Swing Containers tab.
</li>
[*]Click the blue square (described in rollover text as <TT>JPanel</tt>) and
click on your frame to add the panel.
The Property Inspector now displays attributes of the JPanel.
</li>
[*]In the Property Inspector, click twice inside the box beside the name
field.
</li>
[*]Change the name to mainPanel.
</li>
[*]Click the box beside the layout field.
</li>
[*]Choose XYLayout.
XYLayout is an easy-to-use Layout for prototyping. Later, we will change the
layout to a more portable one.</li>
</ol>
Adding Components to the Panel
In this section, we finish laying out a prototype UI. We will add polish and
portability to the UI later.
<ol>
[*]In the Component Palette, select the Swing tab.
</li>
[*]Select the <TT>JTextField</tt> component, which looks like a text field
with a cursor.
</li>
[*]In your panel, click and drag the cursor to outline the text field.
Don't worry if the text field doesn't have exactly the right size or position.
We will adjust these later.
The Property Inspector now displays attributes of the JTextField.
</li>
[*]In the Property Inspector, change the name (just as you did for the
JPanel) to <TT>displayField</tt>.
</li>
[*]Change the text to nothing (erase the value that is already there).
</li>
[*]In the Component Palette, select the <TT>JButton</tt> component, which looks
like a button being clicked.
</li>
[*]In your panel, click and drag the cursor to outline the button.
The Property Inspector now displays attributes of the JButton.
</li>
[*]In the Property Inspector, change the name and action command
to helloButton.
</li>
[*]Change the text to <TT>Say Hello!</tt>.
</li>
[*]Choose File | Save All.</li>
</ol>
