There was some duplication of files in src/main/resources vs src/main/webapp.  I removed the dups from webapp (maven will copy the src/main/resources files to WEB-INF/classes).  I also added some filtering to the serviceParams.properties so that I could replace the mysql properties with values specific to my environment.
Also, I was interested in quickly launching the service without deploying to a separate tomcat instance, so I included the configuration for the maven tomcat plugin.  The following command will launch the infobutton-service in an embedded tomcat and will override default jdbc props with my specific values.  The following screenshot demonstrates that it works and the results look consistent. mvn clean tomcat7:run-war -Ddatasource1.password=mypass -Ddatasource2.password=mypass -DskipTests
