jNut library
|
||
|
|
~~~~~~~~~~~~
|
||
|
|
|
||
|
|
This directory contains source files for the jNut library,
|
||
|
|
which is a Java abstraction bundle to access NUT server(s).
|
||
|
|
You can use it in Java programs to access NUT's upsd data server in a simple
|
||
|
|
way, without having to know the NUT protocol.
|
||
|
|
|
||
|
|
jNut building requirements
|
||
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||
|
|
|
||
|
|
jNut requires to be build :
|
||
|
|
- A Java JDK 6 correctly set in environment (ie bin folder in path)
|
||
|
|
- A Maven 3 installation set in environment (ie bin folder in path) with
|
||
|
|
sufficient configuration (internet connection, local repository) to let maven
|
||
|
|
get all plugins to make processes.
|
||
|
|
|
||
|
|
jNut is written in Java SE 1.4 and is tuned to be compiled to Java 1.4 code
|
||
|
|
level so most of environment can use it.
|
||
|
|
|
||
|
|
jNut building
|
||
|
|
^^^^^^^^^^^^^
|
||
|
|
|
||
|
|
Once JDK and Maven installed and configured, just go into the jNut directory
|
||
|
|
and type:
|
||
|
|
|
||
|
|
mvn install
|
||
|
|
|
||
|
|
The produced package called 'jNut-x.x-xxx.jar' is located in 'target'
|
||
|
|
subdirectory.
|
||
|
|
|
||
|
|
jNut javadoc
|
||
|
|
^^^^^^^^^^^^
|
||
|
|
|
||
|
|
You can generate jNut javadoc by typing:
|
||
|
|
|
||
|
|
mvn javadoc:javadoc
|
||
|
|
|
||
|
|
Documentation will be generated in 'target/site/apidocs' subdirectory and its
|
||
|
|
entry point is located at 'target/site/apidocs/index.html'.
|
||
|
|
|
||
|
|
Workspace cleaning
|
||
|
|
^^^^^^^^^^^^^^^^^^
|
||
|
|
|
||
|
|
The jNut workspace can be cleaned by removing the 'target' subdirectory or by
|
||
|
|
typing:
|
||
|
|
|
||
|
|
mvn clean
|
||
|
|
|
||
|
|
Unit test notes
|
||
|
|
^^^^^^^^^^^^^^^
|
||
|
|
|
||
|
|
jNut sources embed some unit tests in the 'src/test/java' subdirectory.
|
||
|
|
These tests are based on JUnit and are executed between compilation and
|
||
|
|
packaging phases at each build.
|
||
|
|
|
||
|
|
Implementation notes
|
||
|
|
^^^^^^^^^^^^^^^^^^^^
|
||
|
|
|
||
|
|
Currently, jNut is not thread safe. It is not protected against concurrent
|
||
|
|
queries but queries to different clients can be done in parallel as there are
|
||
|
|
done on different sockets.
|
||
|
|
|
||
|
|
Moreover, jNut have no connection preservation system so servers can break down
|
||
|
|
connections due to timeout.
|
||
|
|
Application using retrieved data must forget them when a disconnection occurs.
|
||
|
|
If the application want to maintain the connection, it must implement a
|
||
|
|
ping-pong mecanism itself.
|
||
|
|
|
||
|
|
At present time, jNut do not support SSL connection. It is planned for near
|
||
|
|
future.
