Make the build file automatically adjust itself to compensate for this tomcat version-dependent-behavior:
To use the "deploy" target in build.xml, you'll need to undo a hack I had to put in to work with tomcat 5.0.30. In old tomcat, it was necessary to append a space to the localWar attribute of the deploy task:

tomcat 5.0.30
  <deploy url="${tom.url}"
             username="${tom.username}"
             password="${tom.password}"
             path="/${build.branch}"
             localWar="file://${LPS_HOME} " />

In tomcat 5.5.23, that space is no longer necessary, and in fact, it causes problems. Therefore, eliminate the space, like this:
         <deploy url="${tom.url}"
             username="${tom.username}"
             password="${tom.password}"
             path="/${build.branch}"
             localWar="file://${LPS_HOME}"/>
