classpath

classpath variable is set for providing path of all java classes which is used in our application. All classes related to servlet are available in lib/servlet-api.jar so we set classpath upto lib/servlet-api.jar.

Set Classpath in Servlet

Copy Servlet-api.jar file location and set the classpath in environment variable.

If your classpath is already set for core java programming, you need to edit classpath variable. for edit classpath just put ; at end of previous variable and paste new copied location (without delete previous classpath cariable).

In the above image you can see "C:\Program Files\Java\jdk1.6.0\jre\lib\rt.jar" path is already set now you can only put your servlet-api.jar location at the end of this path. Finally your complete path is;

C:\Program Files\Java\jdk1.6.0\jre\lib\rt.jar ; C:\Program Files\Apache Software Foundation\Tomcat 7.0\lib\servlet-api.jar.;
