Why not simply call catalina.sh from ant?

For example, this is my "tomcat-start" target (it's verbose, but useful):

  











  




===
Starting Tomcat
===
JAVA_HOME is ${app.java-home}
JAVA_OPTS is ${effective.JAVA_OPTS}
CATALINA_HOME is ${app.tomcat-home}
CATALINA_BASE is ${app.home.dir}
CATALINA_OPTS is ${effective.CATALINA_OPTS}
security-option is '${security-option}'



  
  
  
  

  
  




  
  
  
  
  

  
  

  

Now I don't have to worry about things like proper CLASSPATH, updating
my script when some launch parameter changes, etc.

There are two ways to disable rollover (and thus the date in the filename):

a) There is property in JULI FileHandler to disable rollover.
b) You can use FileHandler class from JDK instead of JULI one.

The above is wrong.

The Bootstrap class should locate & load libraries by itself (thanks
to configuration in conf/catalina.properties). The above puts the
libraries in the System classloader, which is wrong.

http://tomcat.apache.org/tomcat-7.0-doc/class-loader-howto.html

One more error in the above:
note that Tomcat configuration for Common classloader includes not
only "lib/*.jar" but also "lib/" directory itself.

Your configuration includes *.jar files only. Class files and
resources (such as the log4j configuration file) will not be seen by
libraries loaded with the above System classloader configuration.

The below is OK.
