I found that it is really important to have exact version of jars specified. The easiest way to do this is run the
maven script that comes in the download for the tutorial. Run the "mvn install" command first. Be sure you have the jta jar. Delete the
test dir from the source code unless you have
junit (they do not have it in the pom.xml).
Then run "mvn package" and maven will get all the dependent jars and then puts the app source and war file in a directory called "target". The jars are in target/quickstartSNAPSHOT/WEB-INF/lib.
