To build BELTS you'll need the source. This can be obtained by following the links at the BELTS SourceForge site. Provided you have CVS installed anonymous CVS access is probably the best way to get the source. If you're unsure how to use CVS, there is plenty of documentation on the Sourceforge site.

cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/belts login
cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/belts co -d belts belts-all

Once you've downloaded or fetched the source, you should have a directory that looks something like this.

[kevin@titus belts]$ ll

drwxrwxr-x    6 kevin    kevin        4.0K Aug 15 10:25 build

You'll also need a local copy of JBoss. This must be version 3.2.0. No other version will work. Unpack the distribution and put it in a directory named jboss.

Copy build/etc/local.properties-example to build/local.properties

[kevin@titus belts]$ cp build/etc/local.properties-example build/local.properties

Edit build/local.properties using the text editor of your choice. At the bottom of this file is a property belts.package-path. Set this to the directory containing the jboss directory created earlier.

#
# Root Path for Thirdparty Packages
#
belts.package-path=/home/kevin/tools
            

Now all you have to do it build it using build/build.sh on Linux or build/build.bat on Windows. The output should start something like this:

[kevin@titus belts]$ ./build/build.sh Searching for build.xml ... Buildfile: /home/kevin/projects/belts/build/build.xml

and end something like this:

main: BUILD SUCCESSFUL Total time: 39 seconds [kevin@titus belts]$

If you have any problems building BELTS, the best place to go for advice and help is the BELTS SourceForge site and the belts-developers mailing list.
