How to get Eclipse to recognize Java EE jar files so that servlets can compile?

Question

I am configuring the Eclipse version for Java EE to compile Servlets. I have a problem when Eclipse says that "HttpServlet" cannot be resolved because it cannot find Java EE jar files.

I am using Windows XP. I already have Tomcat 6.0. I think the easiest solution would be to link the servlet-api.jar file with the Tomcat installation.

I added it to the Windows CLASSPATH environment variable. Now it looks like this:.: C: \ Program Files \ Java \ jre1.6.0_04 \ lib \ ext \ QTJava.zip; C: \ Program Files \ Apache Software Foundation \ Tomcat 6.0 \ lib \ servlet-api.jar

This did not work. Am I doing something wrong?

What is the best solution?

Answer 1

You can add the servlet-api.jar file to the project properties. In the project hierarchy, right-click on the project name-> properties-> Java build path-> Libraries. From there, add servlet-api.jar as an external jar file.

Answer 2

First add Tomcat Server by going to New -> Server -> Server. Then right-click on your project, select "Build Path" → "Configure Build Path". Click Add Library → Server Runtime and select Add Tomcat Server.

Answer 5

java :

• eclipse 'lib'.

• Right-click the servlet file file in the Navigator view and select Add to Create Path.

For more complex projects, I would suggest Maven + m2eclipse.
