Tomcat comes bundled as part of JBoss and it can be found in: %JBOSS_HOME%\server\default\deploy\jbossweb-tomcatxx.sar (depending on which version of JBoss you are using). However the contents of jbossweb-tomcatxx.sar are not the same as that you will find in a standalone tomcat. This folder will not contain any bin or lib directories. All the necessary jars are directly placed inside this folder. You will have to change the build script accordingly.
