I have the following installed.

Eclipse Java EE IDE for Web Developers.

Version: Luna Service Release 2 (4.4.2)
Build id: 20150219-0600


I have added a tomcat7 server. When I attempt to run the server , I get the following. How do I determine what source is missing?

java.lang.ClassNotFoundException: org.apache.catalina.startup.Catalina
at java.net.URLClassLoader.findClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at org.apache.catalina.startup.Bootstrap.init(Bootstrap.java:236)
at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:426)

Let's make sure you...

a. Added the server to the Eclipse workspace (via Window -> Preferences
-> Servers, etc.)

b. Created a Server in the workspace (should see a Server "project" in
the Project Explorer)

c. aren't talking about launching Tomcat from outside Eclipse, right?

d. Right-click your application project, choose Build Path and the
Libraries tab, you see the library/JARs for Tomcat, right?

e. The server you added was a version of Tomcat unpacked from an archive from apache.org, so all of the necessary jar locations were known and used when launching it?
