The maven way

To run the project this way you will need maven installed.
  1. Download the zipped project
  2. Download jta jar from here.
    • Note that the Download Manager may save the file to your root drive, and it may give the file a .ZIP extension. You must rename the file to jta-1.1-classes.jar.
    • If a later version is available, update the version references in the next step.
  3. Install the jta jar file running: $ mvn install:install-file -DgroupId=javax.transaction -DartifactId=jta -Dversion=1.1 -Dpackaging=jar -Dfile=c:\path\to\jar\jta-1.1-classes.jar
