Hello,

We have a problem while trying to run a secure applet. We
made a applet consisting of tow classes. We compile this
applet and sign it using the examples on java.sun.com/security/signExample/
and add it to the a .jar-file (both classes and the
HTML-file). Then we try to run the applet under Netscape
4.05 using the Java-plugin 1.1.1. Our applet is a
clientprogram that tries to connect to a serverprogram on
another computer through sockets (which is the reason we
want to make is secure).

The applet doens't load, but gives the following message:
"Applet Client notinited". The javaconsole gives this:

JAR cache enabled.

java.lang.NullPointerException:

at java.util.Hashtable.get(Hashtable.java:267)

at java.util.Properties.getProperty(Properties.java:279)

at java.lang.System.getProperty(System.java:428)

at java.lang.Integer.getInteger(Integer.java:652)

at java.lang.Integer.getInteger(Integer.java:585)

at Client.init(Client.java:48)

Do you have any idea what is wrong and what can be done
about it?

Thanks,
