You will need to add the required jarfile for the servlet API to your classpath.

Have you installed Tomcat? If yes, then the IDE which you must be using would have an option for setting the class path for you.

Ya i installed tomcat .Do i hav 2 create any xml file for tat servlet program..In book its said tat after compiling in java, its corresponding class file should be pasted in root directory of tomcat.. But its not compiling...???

Yes you have to create web.xml entry for that servlet program and also set the classpath to point to your servlet and jsp jar files.
