I have Eclipse Indigo for Java SE and I have Tomcat in Ubuntu. I would like to develop a Java EE application, using Servlet and JSP.
My Eclipse doesn’t include Java EE support. Can I add this somehow? If yes, any extra tool or plugin I need to install or download?
Yes. You’ll need to use a server like Tomcat to run your application anyway. (Which you have already.) It comes with <tomcat install>/lib/servlet-api.jar. Just include this in your classpath when developing so the code compiles.
Since Tomcat doesn’t support the full Java EE spec, it only gives you the Servlet APIs. But that is enough for what you are doing.
