You don't see the SpaCal Display applet?

Although Java is enabled in your browser preferences? This means your browser doesn't include the Java 2 Runtime Enviroment Version 1.3, which is necessary to run this applet. Here's what you can do first:

Try with Netscape 7 or Mozilla;
Try with the Internet Explorer Version 5 on Mac.

In any case the runtime environemnt of J2SE 1.3 or higher or a complient environment should be installed on your computer. Then you have the following choices:

Run the Sun's browser "Applet Viewer". At DESY UNIX clusters you have to initialise the proper JDK version first:
```
  ini jdk3
  appletviewer http://www-h1.desy.de/h1det/calo/spacal/spdisplay/
```

Alternatively, at DESY you can start the similar stand-alone application:
```
  spdisplay
```
located in /h1/bin on Linux workstations;

You can launch the spdisplay application directly from your browser (also outside DESY) if the Java Web Start is installed on your machine;

Finally you can try to activate the Sun's J2SE1.3 plug-in in Netscape/Mozilla or Internet Explorer:
- For UNIX Netscape 4 you only have to redefine the shell variable NPX_PLUGIN_PATH by adding the plug-in path .../jdk1.3.1/jre/plugin/i386/ns4 before starting the browser. At DESY LINUX clusters Netscape is launched through the shell script /usr/local/bin/netscape, in which this variable is defined, therefore you have to copy it to your home directory and change the definition for NPX_PLUGIN_PATH like this:
```
  NPX_PLUGIN_PATH=$HOME/.netscape/plugins:$TSTHOME/products/jdk/linux/j2sdk1.4.0/jre/plugin/i386/ns4:$NSHOME/lib/plugins
```
  Now, restart Netscape from your script and open the same applet with the plug-in;
- If Netscape 6 or Mozilla is installed on your machine, try the following:
```
  ln -s $TSTHOME/products/jdk/linux/j2sdk1.4.0/jre/plugin/i386/ns600/libjavaplugin_oji.so $HOME/.netscape/plugins/
```
  (JDK path is given for the DESY LINUX installation), then restart Netscape and open the same applet with the plug-in. Hopefully, it will work.
- For Internet Explorer just click on the page: applet with the plug-in and then download and install the plug-in.
