This is a short description on the use of the java demo,
a client that initiates and uses a random number generator
that lies on a java-server. You will be able to shift the
existing client/server with the ones refered to the other
examples.
Instructions.
1) Start erlang
On the erlang shell type :
--------------------------
ic:gen(random,[{be,java}]). ( generates the java code )
2) Modify the "SNode" string on file "server.java" to the server
node name thet suites for your machine.
3) Modify the "SNode" string on file "client.java" to the client
node for your machine and the "PNode" string for the server
node ( = the same as the SNode for the "server.java" file ).
4) Set and export the CLASSPATH variable to point to the
java classes located in java development kit, the
Otp's classes and the current directory.
Your classpath should look like this :
.:<OTPROOT>/lib/ic-4.0/priv/ic.jar:<OTPROOT>/lib/jinterface_1.1/priv/OtpErlang.jar
where :
<OTPROOT> is the location there OTP is installed
5) Start the empd deamon by using the command :
epmd -daemon
6) Compile the generated java code :
javac rmod/*.java ( compiles all generated java code )
javac *.java ( compiles all manually writen java code )
7) Start the java on an terminal window :
java server ( starts the java-server )
8) Start the client on an terminal window :
java client ( calls the server )
