type that.
so i tried using html file, but here aksing plugin download.You will need the java plugin for whatever web browser you are using. Go to its web

Something like this should workjava -cp /path-to-external-jar:SMSClient.jar TheMainClassWhen you use the -jar option, the -cp option is ignored. If you want to use -jar, you can add a Class-Path entry into theSMSClient jar's manifest with the relative path to the external jar.

Mozilla 1.4.2 and Java Applets on Linux

Hello,
Does anyone have clue as to why the newest version of java does not work on Mozilla -1.4.2 on linux.
I went to java.com and downloaded the jre. Followed all the setup instructions TWICE. Still no java. I look in the help/plugins and see the flash plugins are working great but no java. It's enabled in the advanced preferences and I have the .so file in the plugins directory. Anybody have a clue???
Thanks for any help in advance,

[root@localhost mozilla]# ./mozilla
You're using the 'root' account to do normal work?????-------------------------------------------
Yes I did do that when I su root to create a symbolic link. Maybe I strayed and installed something as root. That should not have corrupted my system.
/usr/local/mozilla/plugins/java2/plugin/i386/ns600/libjavaplugin_oji.soThis was something I tried as last ditch efforts. THIS is the link that is created when in version 1.7 of mozilla you go to a page that has an applet. It gives you a download window that askes if you want to download the plugin. I'm using the LATEST version of java and this link does not exist obviously.
Now I've given up on the "pop-up/ install applet plugin becuase it does not work." THIS IS THE LINK CREATED BY THE "INSTALL PLUGIN WINDOW in version mozilla 1.7 when you hit an applet page".... which I have removed it all becuase its worthless too.
/usr/local/mozilla/plugins/java2/plugin/i386/ns600/libjavaplugin_oji.so
Also - The directions given on LINUX INSTALL INSTRUCTIONS on the http://www.java.com download page are worthless.
I've gone in as a normal user not root and nothing works.
this is where my link is....
/usr/local/mozilla/plugins/libjavaplugin_oji.so
this is where it points to....
<java-home>/jre/plugin/i386/ns610-gcc32/libjavaplugin_oji.so
this is how it was created in the mozilla plugins directory
ln -s <java-home>/jre/plugin/i386/ns610-gcc32/libjavaplugin_oji.so /usr/local/mozilla/plugins/libjavaplugin_oji.so
If you look at the installation instructions again, I have followed them to a T.
these are the errors associated with the worthless"Download Plugin option" which has been removed and I'm back to creating the symlink manually again which does not work.
libXext.so: cannot open shared object file: No such file or directory
libstdc++-libc6.1-1.so.2: cannot open shared object file: No such file or directory
This sounds like you may be missing some important software libraries or that they are too old. Which >distro are you using?
If you have only recently installed them you may need to run "ldconfig" so that the runtimelinker can find >them. It should NOT be this big of a headache when I recently installed redhat enterprise 3 workstation - then I updated the system with the "updates" option for redhat that downloads all recent and available updates.
installed the jre - then I tried to see an applet in mozilla. Thats it.
IT DOES NOT WORK. If it works for someone out there with the latest JRE and mozilla-1.4.2 or 1.7 thats great but I can't seem to figure why I can't get it to work........

[SOLVED] Where do I find "applets" for linux?

Hi, do you know those things we put on linux desktop that measure cpu, memory, disk usage, network, etc? So, how are they called: applets, gadgets, monitors, icons, plugins?
I think they are so cool!! They make the system really beatiful, and there are many of them that we can customize a lot.
I'm looking for some to use with WindowMaker, AfterStep and LXDE.
But I don't know where to find them (neither how to call them), so, could anyone please tell where to find them?
Thanks!!

Yeah, that's it, maybe widgets is a better name to describe them.
Actually what I was looking for is a site specialized on it, that contains lots of them. Do you know any?
After a quick search on google, i found this one: http://www.instantfundas.com/2007/10/8- … tform.html. I'll try them to see which are better.
Widgets are pretty cool, and they would be a strong reason for me to move from LXDE to WindowMaker or Afterstep, as they can make these WMs look very nice.
Well, I'm moving this topic to SOLVED. From now on, if I need more help I can find by myself.
So, thanks for the suggestions guys.

EJB access from applet on Linux

Hi,
I've been trying for 2 days now to access an EJB in JServer from a Java Applet running in the Java Plugin 1.2.2 in Netscape on Linux.
After loading the applet web page the plugin fires up and downloads a whole bunch of needed classes. Then I get this exception:
java.lang.ExceptionInInitializerError: org.omg.CORBA.INITIALIZE: can't instantiate default ORB implementation

at java.lang.Thread.run(Thread.java, Compiled Code)
The frustrating part is that the same applet works just fine when called in a Win NT broswer (IE and Netscape) or appletviewer. A java test application accessing the EJB also runs fine on Linux.
The only obivious difference is that my Windows machine has the Java Plugin 1.3 installed and Linux only 1.2.2. But since the applet has been compiled with the 1.2.2 compiler that shouldn't really make a difference, should it?
I'd appreciate any help on this subject.
Thx,
Thomas J.

i could answer this
but my colleagues are working on a client which uses client(applet) to access stateless session beans
but mine's giving a little problem
visit my problem for some of the overview which i think will be fixed or
the same could run on your machine

Mozilla 1.4.2 and Java Applets on Linux Red Hat

Hello,
Does anyone have clue as to why the newest version of java does not work on Mozilla -1.4.2 on linux.
I went to java.com and downloaded the jre. Followed all the setup instructions. Still no java. I look in the help/plugins and see the flash plugins are working great but no java. It's enabled in the advanced preferences and I have the .so file in the plugins directory. Anybody have a clue???

Which Java version are you trying to install? The version of Mozilla you use doesn't matter, although I think 1.6 is quite a bit faster than 1.4. I haven't bothered to upgrade to 1.7, I'll upgrade to 1.8 when it's released ...
The j2sdk comes with several libjavaplugin_oji.so files for different configurations. To which one does the link in the plugins dir point?
With 1.4.2 the link must be to <java-home>/jre/plugin/i386/ns610-gcc32/libjavaplugin_oji.so
With 1.5.0 beta 2 <java-home>/jre/plugin/i386/ns7/libjavaplugin_oji.so

Can't parse xml from applet using dom on linux on Netscape 7 using jre 1.4.

Hi,
I can't seem to parse xml from an applet on linux on Netscape 7 using the JRE 1.4.
My code looks like the following:
StringBufferInputStream is = new StringBufferInputStream("<foo></foo>");
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = null;
try
  builder = factory.newDocumentBuilder();
  domDocument = builder.parse(is); // this line creates an exception
catch (Exception e)
  System.out.println(e);
This code works fine from an applet on windows. On linux, the error message is:
java.security.AccessControlException: access denied (java.util.PropertyPermission entityExpansionLimit read)
I've tried both JRE 1.4.0_04 and 1.4.1_03
Thanks!
Q

There's another posting about this same problem (platform unspecified), but the same error message. I was also having this problem (Windows 1.4.03) and swithced back to 1.4.01 and the problem went away. In the future, I may sign my applets to get a more generous security policy. But, I'm sure it'll be a lot of work (vs. a line of code somewhere).

SetForeground in Applet does not work (Netbeans under Linux)

I'm attempting to make a Breakout version of java (if I go through with it) and the first issue that I encountered is that I can't change the color of the moving rectangle (you know, the thing you hit the ball with). I tried the code under Textpad on a Windows machine and that worked fine, but not under Netbeans in Linux using jdk 1.6.0_01.
import java.awt.*;
import java.applet.*;
import java.awt.event.*;
public class Breakout extends Applet implements MouseListener, MouseMotionListener{
     int mouse_x, mouse_y;
     Thread t;
     public void init(){
          addMouseListener(this);
          addMouseMotionListener(this);
     public void start(){
          t= new Thread();
          t.start();
     public void run(){}
     public void mouseClicked(MouseEvent me){ }
     public void mouseEntered(MouseEvent me){ }
     public void mouseExited(MouseEvent me){ }
     public void mousePressed(MouseEvent me){ }
     public void mouseReleased(MouseEvent me){ }
     public void mouseDragged(MouseEvent me){ }
     public void mouseMoved(MouseEvent me){
          mouse_x = me.getX();
          if(mouse_x>=400)
               mouse_x=400;
          repaint();
     public void stop() {}
     public void destroy(){ }
     public void paint(Graphics g){
          setBackground(Color.black);
          setForeground(Color.white); //doesn't work
          g.drawRoundRect(mouse_x, 600, 50, 20, 20, 20);
}I'm wondering if it's because the Applet under Linux uses the Native l&f theme while appets under Windows uses the Windows l&f theme.
Any thoughts would be helpful!

setForeground(Color.white); //doesn't work
g.drawRoundRect(mouse_x, 600, 50, 20, 20, 20);Change this to:
g.setColor(Color.WHITE);
g.drawRoundRect(mouse_x, 600, 50, 20, 20, 20);You can move the background setting into method init(), calling it once is enough.
I'm wondering if it's because the Applet under Linux
uses the Native l&f theme while appets under Windows
uses the Windows l&f theme.You use java.awt.Applet, so you use AWT which means there's no L&F theme (as in Swing) but it's native components being responsible.

this applet works fine on Windows...
please anyone!

To determine if your browser can view applets, try
viewing the "Cubic" applet on the following page..
http://java.sun.com/docs/books/tutorial/2d/display/Cubi
.html
You will notice that you can manipulate the pattern of
the applet by dragging the colored squares. Thanks for the pointer - it does, indeed, work as expected.
It's a bummer that the "sample applets" are screwy, as that seems like a good place to go to confirm that you have everything configured right (well, it DID seem like a good place to go - it seems quite a bit less good now).
Thanks for the help,

How to run ' appletviewer' in linux console ?

i have no idea how to run an applet in linux , thanks very much .

You just type "appletviewer" etc.
You probably have to be running X first.

Proxy Login

Urgent help needed.
I am very confused with how my applets perform on my intranet. When the applets are loaded on a machine within the domain the server is held, there is no problem as to what the applets can do, but when they are loaded outside the domain, and have to go through a proxy server, access is denied. Another strange thing that happens, is that when a specific applet is loaded, the user is prompted for their username and password for the proxy, but this doesnt happen with any of the others. Also, if the user cancels the login, the applet is restricted, and the user is never asked to login in again. Any help would be greatfully appreciated, as I dont know whether this is a problem with the JSP or the Applet. I also need to try and fix this problem asap, because the current fix just doesnt make sense, i.e. to make the user login to the applet that prompts for the proxy login, and then use the other applets,
Thanks in advance,
Osian

Plugin has nothing to do with servlet or JSP. In IE, applets using AWT will not need a plugin. The jre that comes with Netscape 6.x and Mozilla also gives the same problem. As a result, I have not been able to see applets from linux.
Can someone help?
