Installing and configuring Netbeans and JDK

On this web page we will describe how to install the necessary software to work with the lcsim software framework. The lcsim reconstruction and analysis framework is java based and therefore works on Linux, Windows and MacOSX. In this tutorial we describe the installation and configuration of the following three software packages.

  • netbeans: An IDE (Integrated Development Environment) that simplifies editing and developing the code, building it etc.
  • the java based reconstruction framework.
  • JAS3: is a general purpose, open-source, data analysis tool with the following features
    • Plotting of 1d, 2d and 3d histograms, XY plots, scatterplots etc.
    • High quality print output.
    • Fitting (binned or unbinned) using an extensible set of optimizers including Minuit.
    • Export of plots in a variety of formats including PS, EPS, PDF, SVG, GIF, PNG.
    • Easy to learn GUI for performing common analysis tasks (plotting, ntuple-analysis, fitting etc.).
    • More complex analysis can be performed using a variety of scripting languages (pnuts, jython, etc.), or by writing Java analysis modules.
    • Able to read data in a variety of formats including: SQL databases, text-files (see also HEP specific features).
    • AIDA compliant analysis system.
    • Built-in editor and compiler.
    • Simple spreadsheet capabilities.
    • Logbook for recording analysis tasks, and optionally publishing results to the web.
    • Highly modular structure allows addition, replacement or removal of modules to customize application for a particular problem domain.
    • Plugins provide:
      • Event browser for files in stdhep and lcio format
      • WIRED Event display

Preferred Installation

The machines at the Fermilab computer training center were preinstalled with Scientific Linux Fermi (SLF) 6.3 (32 Bit).  For both windows and Linux we recommend using the netbeans jdk bundle. To install it first get the netbeans java jdk bundle from below.

make the installation script executable and execute it (check the Preferences of your Browser to find out where the file is downloaded):

chmod +x /[path to your Download area]/Downloads/

/[path to your Download area]/Downloads/

On MacOSX Java is usually installed and  it one can just use the existing version. If it is not installed one can get it from the Apple download side:

Then one can obtain netbeans from:

Alternate Installation of NetBeans and JDK

If the bundled installer doesn't work, you can try these directions. This is not preferred because the JDK binary installs to your root filesystem instead of in your home folder. Obscure versioning conflicts may occur.

Get JDK (6u38) from below and follow the installation instructions.

Get NetBeans (7.2.1) in the Java SE bundle from below and follow the installation instructions. Then follow the same instructions for installing and configuring CVS in NetBeans.

Configuring NetBeans

Now, launch NetBeans. Since the lcsim software is located in the CVS code repository first get the necessary CVS plugin for NetBeans

Select Tools-> Plugins->Available Plugins

then select CVS -> Install and accept the licence agreement and click finish.

Getting and Building lcsim Software

Now to install the lcsim framework:

select Team->CVS->Checkout

specify the CVS Root as shown below and leave the password field blank

(Note: Click on thumbnail to expand. If that is still too small, right click and select 'Open in Image New Tab...')

Click the Next button and type GeomConverter into the Module field. Click Finish and the package will begin downloading.


After you clicked Finish, NetBeans will pop open a window asking if you want to open the project.

Click OK / Create Project / Open Project and run the priming build when it asks. This will take a while since initially all necessary libraries need to be downloaded from the maven code repositories. Hopefully in the end it will say:


(Note: org.lcsim will not build successfully until GeomConverter has been built)
So repeat the process for the lcsim module.
Open the project right click on org.lcim and select build. Again this will take a while. To speed up the process in the future you might want to select to skip the tests the next time you build.

Right click on the org.lcsim package and do:

org.lcsim_> Properties->Build->Actions-> Build project -> Add-> skipTests=true

org.lcsim_> Properties->Build->Actions-> Clean and Build project -> Add-> skipTests=true

lcsim-contrib and mcd-analysis

Repeat the above process for the lcsim-contrib and mcd-analysis modules. You can also browse the ilc repository by clicking Browse... instead of typing in the module name

Getting and configuring JAS3

The latest version of JAS3 is 0.9.9:

Run the following command to extract JAS3
tar xzvf /[path to your Download area]/Downloads/jas-assembly-0.9.9-distribution.tar.gz

and then launch it with:

You may want to create a shortcut pointing towards this executable. The jas-assembly-0.9.9 folder includes an icon for this (jas3png).

From the menu bar select View -> Plugin Manager.

Now choose the Available Tab, and select all of the following:

from hep -> visualization:

  • HepRep Plugin
  • WIRED 4
  • WIRED 4 Base Library

(Note: if you have properly built the org.lcsim package in NetBeans, the org.lcsim plug-in should already be listed as installed in the Plugin Manager when you first run JAS3)
from hep -> linearcollider

  • org.lcsim

If you used the netbeans jdk bundle (windows and linux)  make sure you use the same Java that was bundled with netbeans and that you build lcsim etc. with:

From the menu bar select View -> Preferences -> Java -> Compiler

and set to the correct javac:
/[path from which you ran the JDK+NetBeans installer]/jdk1.6.0_38/bin/javac

(Note: on MacOSX this step is not necessary)
(Note: if you used the Alternate Installation instructions, JAS will likely already have the correct compiler set. If not, try /usr/bin/javac)
