在Eclipse中添加外部库

Question

I create new projects in Eclipse regularly and every time when I add a Servlet to one of them I get the error import javax.servlet can't be resolved

To solve this I have to add a jar to the project.

So is there any method such that the required JARs are added to all of my projects ,ie, I don't have to add them again and again whenever I create a new project.

Answer 1

You should be using Eclipse IDE for Java EE Developers and creating each project as a Dynamic Web Project . It will ask you which container you are using (like Apache Tomcat 7.0.x ), but it will add the necessary JARs to the classpath for you. Anything you drop in your WEB-INF/lib folder will also be added automatically to the classpath.
