The applet must be compiled with Java 1.4, not Java 1.5. Many browsers do not support the more recent version.
The command for compiling the applet is
cd ~/public-web
javac -source 1.4 -target 1.4 asldbsearch.java
jar cvf asldbsearch.jar asldbsearch*.class
jarsigner -keystore rvlkeystore asldbsearch.jar rvlalias
password: rvl2asl
The last two of these commands pack the applet into a jar file and sign it. This allows us to open the socket connection. See the next section for more details.
