Installing JAS3

Java Analysis Workstation 3 (JAS3) is a graphical workbench application that can be used for viewing and manipulating AIDA histograms, viewing event displays, and looking at basic information contained in LCIO files.

Before You Start

If you have installed JAS previously, then you may want to remove the existing plugin configuration to avoid conflicts with the new installation.

cd ~/.JAS3
mv extensions extensions.backup

The new plugin jars will be downloaded automatically later when configuring the plugins within JAS.

Getting the Distribution

You can download the latest distribution from the download area either by clicking the links and using the browser or executing a command like this.

wget http://java.freehep.org/maven2/org/freehep/jas-assembly/3.1.0/jas-assembly-3.1.0-distribution.tar.gz

The above command is just an example.  In general, the current distribution should be used.

Installing the Distribution

Once the tarball is downloaded, you can unpack it with a Unix command.

tar -zxvf jas-assembly-3.1.0-distribution.tar.gz

This will create the directory jas-assembly-3.1.0 which is the root directory for running JAS.

Running JAS

Finally, you can simply run JAS from the command line using a simple command such as the following.

 ./jas-assembly-3.1.0/jas3

You should now see the GUI load.

Configuring Plugins

Next we need to install the plugins used for analyzing HPS data.

In the View menu, click on the Plugin Manager item and find the HPS Java plugin in the tree menu.

You can install the plugin by clicking on the Install selected plugins button.

When prompted, restart JAS3 by clicking on the Restart Now button.

The other plugins on which HPS Java depends will be installed automatically through dependency resolution, so you should be good to go now!

How Do JAS3 Plugins Work

JAS installs jar files for plugins into ~/.JAS3/extensions which are automatically loaded when the application starts. 

Installing the Plugin from HPS Java

When developing HPS Java, you may want to update JAS3 with changes from your local installation.  In order to do this, you will need to install the hps-plugin module.

It can be installed by itself as follows.

cd hps/java/trunk/plugin
mvn

Once this is done, you will need to restart JAS for it to load the modified jar files.

The plugin is also installed automatically when building the entire trunk.

cd hps/java/trunk
mvn -DskipTests

This should make sure that JAS sees your local version of the HPS Java Plugin.
