ivy-java README
Last modification, lun jan 6 16:25:35 CET 2003 , Yannick
-----------------------------------------------------------------------------
Ivy java is open source software distributed under the terms of the GNU
Lesser General Public License (LGPL). See the COPYING.LIB file for details.
Some included utilities are distributed under the terms of the GNU
General Public License, a copy of which is included in the file COPYING.
This page has been hugely inspired from the one Wes wrote for the gnu-regexp
package. As I am a newbie in package creation, I started from an existing one.
INSTALLING
Copy the ivy-java jar file (located in the 'lib' directory)
to your usual installation directory for Java archives. If it is located in
your main java class repository, it is possible that will just work as is,
however, you might want to put it elsewhere and fiddle with the CLASSPATH
environment variable.
Typically this is done by adding an entry to your CLASSPATH
variable setting with the full path to the JAR file, e.g.
csh: % setenv CLASSPATH ${CLASSPATH}:/usr/java/lib/ivy-java.jar
bash: % export CLASSPATH=${CLASSPATH}:/usr/java/lib/ivy-java.jar
DOS: > set CLASSPATH %CLASSPATH%;C:\Java\lib\ivy-java.jar
Various shells and operating systems may have slightly different methods.
Consult your Java virtual machine documentation for details. You may also
specify the -classpath option to the java executable, e.g.
compile: % javac -classpath /usr/java/lib/ivy-java.jar MyClass.java
execute: % java -classpath /usr/java/lib/ivy-java.jar MyClass
DOCUMENTATION
ivy-java should come with
- one man page: doc/ivy-java.1,
- the javadoc api html documentation tree: doc/api/
- a programmer's guide both in html: doc/programmersguide/
and in pdf format: doc/programmersguide.pdf
If any of those file is missing, see the tar.gz archive on the Ivy java
web page ( http://www.tls.cena.fr/products/ivy/ivy-java.html )
UTILITIES
ivy-java comes with a simple utility program intended to test
and demonstrate its features. It is compiled into the Java archive
file. To run fr.dgac.ivy.Probe, you will need gnu.regexp and gnu.getopt,
which are available at http://www.urbanophile.com/~arenn/hacking/download.html,
and put those class files in your classpath as well.
Running java fr.dgac.ivy.Probe successfully is the key to knowing whether
your ivy-java installation is OK.
Ivy also comes with a simple TCP relay, allowing any script application to
send text messages onto an Ivy bus. To run the relay, launch
$ java fr.dgac.ivy.IvyDaemon
Then any line sent to the local port 3456 will be forwarded as an ivy
message. It can be used in shell scripts in conjunction with netcat
$ echo "hello world" | nc -q 0 localhost 3456
HACKING
You are free to fold, spindle, mutilate and modify this library,
provided you follow the terms outlined in COPYING.LIB. The ivy-java
project team gratefully accepts any bug fixes or enhancements you may
come up with (see the TODO file if you're in need of some ideas). A
few parameters at the top of the Makefile in the 'src' directory
need to be edited to match your local system setup.
BUG REPORTS
Send bug reports to <jestin@cena.fr>, or join the ivy mailing list
by sending a "subscribe" message to <ivy-request@tls.cena.fr>. It helps
if you can send a code sample showing the messages you were
using and how you were using it.
LATEST VERSION
You can always obtain info about the latest version of ivy-java at
http://www.tls.cena.fr/products/ivy/download/desc/ivy-java.html.
Don't hesitate to ask me by mail a cvs snapshot if you're not satified with
the upstream release.
Thanks!
