Two possible issues could be   you either forgot to include Servlet jar in your classpath you forgot to import it in your Servlet class   To include Servlet jar in your class path in eclipse  Download the latest Servlet Jar and configure using buildpath option  look at this Link for more info    If you have included the jar make sure that your import is declared    import javax servlet http HttpServletResponse

You can do the folllwoing  import the jar file inside you class   import javax servlet http HttpServletResponse  add the Apache Tomcat library as follow   Project   Properties   Java Build Path   Libraries    Add library from library tab   Choose server runtime   Next    choose Apache Tomcat v 6 0   Finish   Ok  Also First of all  make sure that  Servlet jar is included in your class path in eclipse as PermGenError said   I think this will solve your error

As a reason of this problem  some code is broken or undefined You may see an error in a java class such as  The type javax servlet http HttpSession cannot be resolved  It is indirectly referenced from required  class files   you shuold download   javax servlet jar  as mentioned before  Then configure your project build path  add the javax servlet jar as an external jar I hope it fixes the problem At least it worked for me
