Tomcat requires a Java runtime environment (JRE) to run. The openjdk-6-jre-headless package is apparently the only JRE installed on your system. You can't remove it but keep Tomcat because Tomcat won't work without it.

If you install some other JRE package first, such as openjdk-7-jre, then you should be able to remove openjdk-6-jre-headless without removing Tomcat, because Tomcat's dependency on a JRE will still be satisfied.

What you want is:

dpkg --force-depends --purge openjdk-6-jre-headless openjdk-6-jre-lib icedtea-6-jre-jvmvm

So, dpkg --force-depends is the key.

As u can see in below message, It describes the packages that are about to get uninstalled.

The following packages will be REMOVED:

ca-certificates-java default-jre-headless icedtea-6-jre-cacao icedtea-6-jre-jamvm   
libcommons-dbcp-java libtomcat7-java openjdk-6-jre-headless openjdk-6-jre-lib 
tomcat7 tomcat7-admin tomcat7-common

Hence it will remove tomcat packages.
