Running Java viewer standalone?

Ripcord · Post by **Ripcord** » 2005-09-11 16:04

Hi,

Does anyone have an easy way to get the the Java viewer to run it standalone? I'd like to take advantage of its multiplatform features and run it on OS X and Linux, but not to connect to UltraVNC servers.

(I also wouldn't want to run it in a browser on my Windows client as the browser consumes too much screen real estate).

Really I just need the .jar, I believe, but I haven't found a way of retrieving it. I see it's not for separate download, and I haven't found a way to extract it from the source tree (I assume I'd have to javac it).

Is the only way to get the .jar to build it myself or to install UltraVNC server somewhere temporarily and pull it out?

Point your browser (or curl, wget, whatever) at http://<vnc-server>:5800/VncViewer.jar and save to a file.

Run with: java -classpath VncViewer.jar VncViewer HOST ... PORT ...

variable: value
CLASSPATH: C:\Program Files\Java\jre1.5.0_04\lib\ext\QTJava.zip
QTJAVA: C:\Program Files\Java\jre1.5.0_04\lib\ext\QTJava.zip

cmd>java VncViewer.jar HOST hostname PORT port (display number)

cmd>java VncViewer.jar HOST hostname PORT 5800
cmd>java VncViewer.jar HOST hostname PORT 0
cmd>java VncViewer.zip HOST hostname PORT 5800
cmd>java VncViewer.zip HOST hostname PORT 0

all have same error:
Exception in thread "main" java.lang.NoClassDefFoundError: VncViewer/zip
Exception in thread "main" java.lang.NoClassDefFoundError: VncViewer/jar

Can't start java vncviewer alone (without web browser or JDK) ?
so I must have JDK 1.4 for start java vncviewer as below like Linux Suse 8.0 tell ?

Installation of VNC java client over Linux Suse 8.0

To run the vncviewer java version run on linux, you need the JDK 1.4 or higher. The procedure to installing an running it is as follows:

1. Download the compiled package.
2. Make sure you have your java virtual machine from the JDK 1.4 in your PATH.
3. Make sure you have set the CLASSPATH
4. Type the next commands.
>tar -zxvf vncjavaIPv6.tgz
>cd vnc_javasrc
5. To run vncviewer, type:
>java vncviewer HOST host PORT port (display number)

Of course you need a JDK or JRE installed; but any 1.2 or later will do. Just follow my instructions exactly. The other instructions, while not wrong, are more complicated than necessary, as you can specify the classpath on the command line ("VncViewer.jar" has got to go into the classpath, and "VncViewer" is the class to run).

finally:
successfully connected

with JRE 1.4.2_09-b05
successfully connected

with JRE 1.5.0_04-b05

the mistake was only "PORT 5800" replaced with "PORT 5900" and it work fine !
Sorry for beginner error of java

I was forgot to consider only 5900 redirected by vncserver to 5800 for java

java -classpath VncViewer.jar VncViewer HOST myremote PORT 5900

roadrunner,
Thank you for your time to Java beginner support and your time for update/create and help UltraVNC Java code.
