LOUI development is best done in with the eclipse IDE. Java 7 and eclipse 3.5 are the minimum acceptable versions for development - using Java 8 and eclipse 3.8.2 is highly recommended.  Errors may occur on 4.x versions of eclipse, and higher Java versions (as of 2019 October) have not been tested.

. Using Java 8 and eclipse 3.8.2 is highly recommended. It is required to download the full Eclipse SDK (e.g. eclipse-SDK-3.8.2-macosx-cocoa-x86_64.tar.gz) from the eclipse download site. If one wants to create products for multiple platforms, downloading the eclipse Delta Pack (eclipse-3.8.2-delta-pack.zip) and setting up a "Target Platform" would also be required. In addition to these download files, one should also use the Eclipse update mechanism to install two a few more packages:

In the "Help" menu option, "Install New Software ..."

• GEF SDK from the standard download site already available in eclipse
• PGroup widget from Nebula project at httphttps://downloadarchive.eclipse.org/nebula/releases/2.0.0/
  • NOTE: This version at least made the getTemp app buildable for me; the latest (2.5.something) had an error related to JRE 1.8 so my guess is nebula dropped Java 8 support somewhere along the way?
  • Add the URL in the "Work with" box, and select the Pgroup widget from the "Nebula Release Individual Widgets" section
• Subversive

Subversive is the subversion (SVN) plugin; you'll need that to get the sources.  It works with the current project sets.  In the past, subclipse was another You'll also want a subversion plugin before you go much further.  Subclipse is one option, but the latest releases need Eclipse 4.2.x so that won't work super easily.  Subversive is available from the repository above, and it works with the project sets.Each required plugin which is not part of the standard eclipse SDK is in the source repository as its own project. Sample list of required projects for the LOUI build project set are as follows:

The repository is subversion and it is on jumar. The connection url is is svn://jumar.lowell.edu

Example checkout syntax from command line:

$ svn checkout svn://jumar.lowel.edu/edu.lowell.loui.nasa42<YOUR DESIRED REPO HERE>/trunk edu.lowell.loui.nasa42 <LOCAL PATH HERE>

Create a new workspace and do the above checkouts and then do the following:

• Create Create /opt/LOUI/ directory  directory for storing the configuration files. Give it permissions and ownership of the your username (or your desired development username)

• Check out the whole tree for the config files

  Code Block
  bash bash
  $ cd /opt/LOUI $ svn checkout svn://jumar.lowell.edu/LOUI_Configuration/trunk/dev .

• Edit the jndi.properties file in /opt/LOUI/(DESIRED LOUI(we reccomend lmi)) to point to the right machine and right broker.

One can either do the checkouts individually using an eclipse subversion plugin, such as subclipse, or use a shell script to do all the checkouts in one operation, or use the eclipse's Team Project Set.

The easiest and fastest way to build the workspace is to use Team Project Sets.

You'll also need to set up the logging path; the apps will technically work without it, but this should not be allowed. Root permissions are fine.

• Create a directory in /var/log/LOUI/

In order for the apps to run properly, the directories for the log files need to be created in advance. The logging framework creates the log files and rotates them automatically but the parent directory structure needs to be in place. The log files are located in directories under Each app has a separate directory under /var/log/LOUI/. Each app has a separate directory. The current list isThe following apps should show up in there:

• cat
• deveny
• getTemp
• gwaves
• igrins
• joe
• joeClient
• lmi
• nightlyReport
• nihts
• observerTargetlist

Once you're up and running minimally, the fastest way to get everything is to use Team Project Sets.

After you retrieve the required plugins, there are a few more libraries that need to be downloaded and installed. First is JUnit:
