I have jdk1.6.0_13 installed, but when I try to find a javax.servlet
package, or press ctrl+space in Eclipse after Servlet
I cannot get anything. Where can I download this package, and why isn't it included in standard distribution for developers?

4Have you instaled the J2EE? If you installed just de standard (J2SE) it won´t find.
javax.servlet
is a package that's part of Java EE (Java Enterprise Edition). You've got the JDK for Java SE (Java Standard Edition).
You could use the Java EE SDK for example.
Alternatively simple servlet containers such as Apache Tomcat also come with this API (look for servlet-api.jar
).
those classes are usually part of servlet.jar

The normal procedure with Eclipse and Java EE webapplications is to install a servlet container (Tomcat, Jetty, etc) or application server (Glassfish (which is bundled in the "Sun Java EE" download), JBoss AS, WebSphere, Weblogic, etc) and integrate it in Eclipse using a (builtin) plugin in the Servers view.
During the creation wizard of a new Dynamic Web Project, you can then pick the integrated server from the list. If you happen to have an existing Dynamic Web Project without a server or want to change the associated one, then you need to modify it in the Targeted Rutimes section of the project's properties.
Either way, Eclipse will automatically place the necessary server-specific libraries in the project's classpath (buildpath).
You should absolutely in no way extract and copy server-specific libraries into /WEB-INF/lib
or even worse the JRE/lib
yourself, to "fix" the compilation errors in Eclipse. It would make your webapplication tied to a specific server and thus completely unportable.
