ClassNotFoundException on main class when no network access

While testing that my Webstart application can run Offline, I ran into the following problem:
[Setup]
Using Webstart 1.6.0_01
Using JRE 1.5.0_07
[Steps to reproduce]
1-While having access to network, download MEdit Webstart application from server
=> MEdit application is properly cached and because of desktop integration parameters, icon is added to desktop
=> MEdit application starts properly
2- Close MEdit application and unplug network cable
3- Double-click on icon on desktop (or go through Control Panel -> Java console) and start MEdit
=> This time MEdit does not start properly and instead, I'm having the following ClassNotFoundException:
java.lang.ClassNotFoundException: com.miranda.medit.MEdit
     at java.net.URLClassLoader$1.run(Unknown Source)
     at java.security.AccessController.doPrivileged(Native Method)

     at com.sun.javaws.Launcher.doLaunchApp(Unknown Source)
     at com.sun.javaws.Launcher.run(Unknown Source)
     at java.lang.Thread.run(Unknown Source)
I checked my jnlp file, but I haven't find any wrong. Does any one have a clue what could be causing the problem? I tried the steps above using demo applications and it I am not having any problem. Thus for sure there something wrong with my .jnlp file or the application itself.
Here is a copy of the .jnlp file:

Ok I found the cause for the problem. It has to do with java.protocol.handler.pkgs in .jnlp file. Webstart uses that property and set it with 'com.sun.javaws.net.protocol|com.sun.deploy.net.protocol'. To fix the bug, I must make sure I append these two protocol handlers, as shown here:
<property name="java.protocol.handler.pkgs" value="com.miranda.monako.dao.url.protocol|com.sun.javaws.net.protocol|com.sun.deploy.net.protocol">

Java can't find main class when manifest has certain JARs on it

I recently wrote an Ant script that builds my application and jars it up, creating a manifest in the process. The manifest specifies the main class and a classpath that mentions other jars that exist in the same directory. Everything works as expected and I am able to run the program using "java -jar abc.jar".
However, I recently started using classes in my program that come from a jar that should (according to the company I work for) reside in a central location rather than each application having its own copy. So, I changed my build script to reference those shared jars in a common location. But now when I run "java -jar abc.jar", I get a java.lang.ClassNotFoundException: com.example.Main. If I edit the jar's manifest and manually remove the new jars from the classpath, the ClassNotFoundException error goes away (although obviously that causes other problems.) Is there something about adding those new jars to the manifest classpath that would prevent Java from finding my main class? My manifest looks something like this and the last two jars (the ones with the absolute paths) are the jars that seem to be the root of the problem.

I still don't know why giving the absolute classpath entry like that would cause Java to be unable to find the jar's main class, but I did make an interesting discovery. If I give the absolute path without the drive letter, is able to find the main class again. Something like this won't work...
Class-Path: C:\software\tibco\ems\clients\java\tibjms.jarBut something like this will...
Class-Path: \software\tibco\ems\clients\java\tibjms.jarBut I'd still like to know why Java doesn't accept drive letters when running on a Windows machine. After all, what if my manifest needed to reference a jar that was on a different drive, like a network drive (since this whole problem came up as a result of shared common jars that need to exist outside of the project.)

Could not find the main class - Problem with Webservice-Access

Hello Everybody,
I'm having serious Problems with accessing a WebService (Tomcat-Axis) per executable jar-File.
I constructed a simple GUI with 3 Textboxes 1 Button and 1 Resultbox.
I use eclipse so it was no Problem to simple generate the Backgroundclient by Processing the .wsdl-File of the WS.
Now I do this:
Head_tServiceLocator serviceLocator = new Head_tServiceLocator();
Head_t service = serviceLocator.getRPCCall();
RPCCallSoapBindingStub Head_t = (RPCCallSoapBindingStub) service;and use the Webservice like an Object.
All this works very well.
Now the Problem:
Head_t service = serviceLocator.getRPCCall();this Line has to throw a ServiceException.
If i add a try-catch Block to Process the Message JAVA tells me after i exported to JAR (with Manifest-stuff and so on) and double Click on the JAR the following :
Could not find the main Class - Program will exit.
And if i add a throws Declaration to the Methodheader it tells me:
Fatal Exception Occured - Program will exit
But if i Comment out that Line at least the GUI is being displayed (so it DOES find the main-Class). But then of course the Webservice won't be accessed.
All the JARs needed (axis.jar, commons-discovery.jar and so on) are in the same Directory as the Webservice-Client.jar
Please Help me.
Greets,
Zap

I am not done any typing mistake while creating the jar file i already followed the suggestion that you have mentioned but still the same error .
This is my MANIFEST.MF file created under META-INF folder

"Could not find the main class" when running a jar

Hi, I'm trying to create and run a jar from my application, but I can't figure out how to properly set an entry-point. Looking at the Java Tutorials http://java.sun.com/docs/books/tutorial/deployment/jar/index.html I still can't get it to work.
I have a directory myApp, which contains a directory images and some class files, including mainClass.class. I also have a manifest Manifest.txt in the directory myApp with the following line:
Main-Class: mainClass.class
+ one empty line
I create a jar successfully, while inside the myApp directory, with the following command:
jar cfm myApp.jar Manifest.txt *.class images\*.*
I then proceed to run the jar with the following command:
java -jar myApp.jar
and receive the following error:
Exception in thread "main" java.lang.NoClassDefFoundError: myApp/class
My completely uneducated guess is that there is something wrong with my manifest. The tutorial says that the line should be:
Main-Class: MyPackage.MyClass
I'm assuming that I get the error because I didn't specify a package, which I didn't do because I didn't know what to put there. Do I even have a package?
Can anyone tell me what I've done wrong? thanks.

One problem is you are specifying a file name instead of a class name. It probably should beMain-Class: mainClassA good test is to run your app before jaring it - if you run it with "java mainClass" then the Main-Class attribute must be mainClass.
Also class naming conventions say that class names should start with a capital letter - MainClass for example. It is just a convention, but it is easier to get help when you follow conventions.

Jnlp main class: static void main() or applet class????

When create jnlp file for applet, I have to specify main class. This "main class", is it the class that contain static void main(), or the applet class. The way I design is the that the applet class will SwingUtilities.InvokeAndWait the "main class".
Should I specify main class when jar the files or in jnlp file?
Lastly, when I upload my jnlp file to my web server, and try to access it through a web browser, it keeps saying that the web address is invalid. Do I need any special permission from the web server to run jnlp file?
Thank you and have a wonderful day

Lastly, when I upload my jnlp file to my web server, and try to access it through a web browser, it keeps saying that the web address is invalid. What address, what URL?
..Do I need any special permission from the web server to run jnlp file?No. All that is required is that it is accessible, and returns the correct content-type for .jnlp files.

Access the property of main class in loaded swf.

Hi
i have one main.fla, its document class is main.as. the code in main.as is
package
import flash.display.MovieClip;
public class Main extends MovieClip
private var loading:Loading;
public var trovami:Number=10;
public function Main()
stage.frameRate=31;
loadSWF();
private function loadSWF():void
loading=new Loading(this);
Loadind.as is another class where i load another swf its name is my_swf.
the code of loading class is:
package
import flash.display.MovieClip;
import flash.display.SimpleButton;
import flash.text.TextField;
import flash.display.Loader;
import flash.events.*;
import flash.net.URLRequest;
public class Loading extends MovieClip
private var _fla:MovieClip;
private var url:String;
public var val:String;
private var loader:Loader;
public function Loading(fla:MovieClip)
_fla=fla;
init();
private function init():void
url='my_swf.swf';
var request:URLRequest=new URLRequest(url);
loader=new Loader();
initListeners(loader.contentLoaderInfo);
loader.load(request);
private function initListeners(dispatcher:IEventDispatcher):void
dispatcher.addEventListener(Event.COMPLETE,completato);
private function completato(event:Event):void
_fla.addChild(loader);
loader.y=10;
val="hello"
and the document class of loaded swf is Main2. in my_swf.fla there is one text its name is:
a_txt.
so i have to use property of Loading class in Main2 for text.
code of Main.as is
package
import flash.display.MovieClip;
import flash.text.*;
public class Main2 extends MovieClip
public function Main2()
a_txt.text=val;
where val is the property of Loading class.
so how can i access.

You have a reference to your loaded movie within your Loading class - instead of just setting val to a string - add a method in your Main2 class - and call that from Loading - passing the string to it. Push not pull...
Main 2 becomes:
public function Main2() {
     //a_txt.text=val;
public function setText(val:String):void {
    a_txt.text = val;
And then in your Loading class - when you're done loading just call setText:
private function completato(e:Event):void
    addChild(loader);
    loader.y=10;
    MovieClip(loader.content).setText("hello");
    //val="hello";

Accessing object of the main class from the thread

Hi, I'm having problem accessing object of the main class from the thread. I have only one Thread and I'm calling log.append() from the Thread. Object log is defined and inicialized in the main class like this:
public Text log; // Text is SWT component
log = new Text(...);Here is a Thread code:
...while((line = br.readLine())!=null) {
     try {
          log.append(line + "\r\n");
     } catch (SWTException swte) {
          ErrorMsg("SWT error: "+swte.getMessage());
}Error is: org.eclipse.swt.SWTException: Invalid thread access
When I replace log.append(...) with System.out.println(..) it works just fine, so my question is do the log.append(..) the right way.

This is NOT a Java problem but a SWT specific issue.
It is listed on the SWT FAQ page http://www.eclipse.org/swt/faq.php#uithread
For more help with this you need to ask your question on a SWT specific forum, there is not a thing in these forums. This advice isn't just about SWT by the way but for all specific API exceptions/problems. You should take those questions to the forum or mailing list for that API. This forum is for general problems and exceptions arising from using the "core" Java libraries.

Silly problem when compiling main class

hi there,
i have a problem when compiling the main class.
the classes used by the main class are not recognized. the compiler can't locate the children classes.
i've already set the path and classpath environment variables, but there's still something missing.
how should i organize my folders in order to be able to compile the main class successfully, please?
thanks.

It would be good to have a precise problem description: the actual command used, folder structure and environment variable settings. Even if you have to construct a simple test case with a couple of classes that illustrates the problem.
In the absence of that some generic remarks:
The PATH variable typically points at all the folders that contain executable files that you use often. You can always access other executable files by specifying there full names.
The CLASSPATH variable is typically left unset.
When you use the java tools (like the javac compiler or the java runtime) you can specify the classpath that you want to use with -cp. This will override any CLASSPATH value. So in the simple case of two classes (Main and MyClass), you can put them in anywhere you like (for example C:\MyJavaStuff) and compile and run with:
{noformat}
C:\MyJavaStuff> javac -cp . *.java
C:\MyJavaStuff> java -cp . Main
{noformat}(Mind the dot after -cp))
By a "main" class I guess you mean a class with a static void main(String args[]) method, but I am suspicious of your "child" classes. Perhaps packages are involved. A precise description of the problem would help.

No shared network access when booted from Firewire

I can't seem to access any volumes on my network when my MacMini is booted from an ext. firewire drive. I've tried to do this from two seperate bootable FW drives and I can't access my NAS or any of the other Macs on my network. This is an issue that I just noticed. I have worked with Macs and PCs across networks for a while but I can't figure this one out for some reason.
I'm running MacMini 1.66 GHz Intel Core Duo and I'm on 10.5.8. Any insight is appreciated. Thanks!

UPDATED/SOLVED---I finally figured this problem out. **Note: This whole process began with the desire to expand my original MacMini's 75GB HD space and to avoid potential disaster. I have recently been going through a spate of HD failures and I really wanted to avoid such a calamity with my main system volume. So the goal was to, in effect, replace the MacMini's drive without having to open it up by simply buying a new 1TB drive and dropping it into a FW enclosure with a huge fan. I had hoped that a simple BounceBack recover would do the trick but I quickly found out that it was not to be.
The problem existed on backup copies that were created by my old version (5.1.4) of BounceBack (that I never updated). For whatever reason, that version excludes necessary components for networking when making bootable volumes. Therefore all my external FW drives that were bootable were not truly complete/useable volumes. Here's how I came to that conclusion and how I ultimately solved the problem.
1. I ended up having to do a reinstall of Leopard. I did this by cloning Leopard install disc to an image file and then restoring that image file to the FW drive. The real purpose of cloning the install disc was to immediately test the veracity of my theory that the problem lay within my BounceBack bootable volumes and not with the FW drives themselves. Sure enough, I found everything to be working perfectly from the newly minted, clean install Leopard FW volume. So then...
2. ...I cloned the MacMini's orginal internal HD. It was the only volume with my most recent system that did NOT have the aforementioned network access problems and it was the volume from which all of the other BounceBack volumes were created.
3. I restored this volume to the FW drive and was rewarded with a brand new, expanded and fully working system volume with all my applications and settings intact.
To be fair, I feel compelled to mention that this is not necessarily an indictment of BounceBack. Again, the copy I was using is several years old and I simply never paid for an update, thinking that the copy I was using was sufficient. I'm willing to bet that the makers of BounceBack solved this problem long ago with one of the many updates since that have been released I first purchased the software. That being said, I'm now using Time Machine for backups of my system volume while utilizing BounceBack for data on other volumes that don't need to be bootable.

The "-cp ." tells Java to ignore the CLASSPATH variable and just look in the current directory instead. You probably had the location of StdIn on your CLASSPATH variable.
What you need to do in this case is to add the current directory "." to your CLASSPATH variable.

Java Access Bridge 1.1 Could not find the main class

When I try to load Java Access Bridge 1.1 I receive the following error:

Does anyone know why?

you must check with the classpath
please see that you have not repeated %classpath%
at the end of the class path like you do in win98.
similiarly with %path%

I have set up a wireless network in my office using a couple of Airport Extremes, and, for some reason, our Windows computers are able to view the password of the network. Well, given that we employ teenagers, you can imagine what happens when they all find out the password. We want to restrict network access to only those devices we deem necessary. How do I accomplish this?

You can keep using your Apple routers as AP devices.. but get a router running a secure OS as the actual router that controls the network..
If you have 18-20 teens on the network.. then setting quota and restrictions on bandwidth is far more important than time..
Gargoyle on a cheap router can do it.. eg WNDR3800 or the newer W1024ND v2.
Simply turn off the wireless in these devices.. and use the ethernet connection to the airport as WAP.
Honestly you just will never get the security or control using apple domestic routers.

I want to be able to access my main computer when I'm away from home. Are there honest and trusted 3rd party applications that allow access to the home computer when I'm traveling?

the job takes me away from home and at times I need information stored on the iMac. I would like to access the main computer and its files through a second computer, Mac Pro. Is there a service that will allow me to access my main computer when I'm traveling? For example if I'm in Brasil and need to access files found in my main computer in Canada, what reliable allows me to connect between the 2 computers?

Yes,

Just installed Firefox for my boss, and ran into something I've not seen before. When trying to access our private camera system, that uses specific ports, I got this message: "This address is restricted - This address uses a network port which is normally used for purposes other than Web browsing. Firefox has canceled the request for your protection."
Cannot find a setting in Firefox to correct this problem. Please help.

Couldyou please help?

Hmm, only way I know would be a relatively painless Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space and no Disk corruption, and is relatively quick & painless...

Just be sure to select Preserve Users & Settings.
