Added a lot of modifications in order to expression a Tomcat configuration better and to perform more efficient management of various Tomcat components.
With these modifications, a user can configure a tomcat instance with web applications and web services by writing a service, such as:
...
services = {
tomcat = {
enable = true;
webapps = [ mypkgs.HelloWorldWebApplication ];
axis2 = {
enable = true;
services = [ mypkgs.HelloService mypkgs.HelloWorldService ];
};
};
};
