Thought I would just post this for reference for others as I had to figure it out today. Perhaps it will save others some time.
Today I installed tomcat6 using:
zypper install tomcat6 tomcat6-admin-webapps tomcat6-docs-webapp
However, I was surprised to discover after starting tomcat and visiting http://localhost:8080/ that only a blank page was displayed. No errors where reported in catalina.out.
I am accustomed to normally seeing the default Tomcat Welcome page being displayed. With Suse, this is packaged separately, so you must also install:
zypper install tomcat6-webapps
(In fact, there is no ROOT directory in /usr/share/tomcat6/webapps until you install this package.)
Also, of course, you must edit /etc/tomcat6/tomcat-users.xml and configure your users and passwords before accessing http://localhost:8080/manager/html
Also of note, the admin panel previously used in Tomcat 5.x is no longer available in Tomcat6 so you will no longer see a link for that on the Welcome page.
