JSP and Servlet are Server side Programming. As it comes as an built in package inside a Server like Tomcat. The path may be like wise

C:\Program Files\Apache Software Foundation\Tomcat 6.0\lib\jsp-api.jar
C:\Program Files\Apache Software Foundation\Tomcat 6.0\lib\servlet-api.jar

Just you want to Do is Add this in the following way

Right Click> My Computer>Advanced>Environment Variables>System variables

Do> New..> Variable name:CLASSPATH
           Variable value:CLASSPATH=.;C:\Program Files\Apache Software Foundation\Tomcat 6.0\lib\servlet-api.jar;

In a linux environment the soft link apparently does not work  you must use the physical path  for instance on my machine I have a softlink at  usr share tomacat7 lib servlet-api jar and using this as my classpath argument led to a failed compile with the same error  instead I had to use  usr share java tomcat-servlet-api-3 0 jar which is the file that the soft link pointed to

Add servlet-api jar into your classpath  It will be available into Tomcat s lib folder

This happens because java does not provide with Servlet-api jar to import directly  so you need to import it externally like from Tomcat   for this we need to provide the classpath of lib folder from which we will be importing the Servlet and it s related Classes  For Windows you can apply this method   open command prompt type   javac -classpath  quot C  Program Files Apache Software Foundation Tomcat 9 0 lib    quot  YourFileName java          It will take all jar files which needed for importing Servlet  HttpServlet  etc and compile your java file   You can add multiple classpaths Eg    javac -classpath  quot C  Users Project1 WEB-INF lib    C  Program Files Apache Software Foundation Tomcat 9 0 lib    quot  YourFileName java

You need to add the path to Tomcat s  lib servlet-api jar file to the compile time classpath  javac -cp    path to Tomcat lib servlet-api jar com example MyServletClass java  The classpath is where Java needs to look for imported dependencies  It will otherwise default to the current folder which is included as   in the above example  The   is the path separator for Windows  if you re using an Unix based OS  then you need to use   instead  If you re still facing the same complation error  and you re actually using Tomcat 10 or newer  then you should be migrating the imports in your source code from javax   to jakarta    import jakarta servlet    import jakarta servlet http     See also   jakarta servlet ServletException  Class  com practice MyServlet  is not a Servlet

Is it a JSP or Servlet   Well  these two packages aren   t actually built into Java like java io is  Instead  they come with the Servlet-capable Web server  e g  Tomcat   So before the Java compiler will be able to compile our Servlet  we need to let it know where to find the classes in these two packages   The classes required are normally stored in a file called servlet jar  The exact location of this file will depend on the particular Web server software you use  but in the case of Tomcat you can find it in the lib subdirectory of the main Tomcat installation directory  e g  d  Program Files Apache Group jakarta-tomcat-3 2 3 lib servlet jar   For the Java compiler to be able to compile Servlets  you need to add this file to your Java class path  By default  Java looks for classes in the current directory       only  Thus      is the default class path  If you change the class path to include the servlet jar file     d     lib servlet jar  under Windows      usr     lib servlet jar  in Unix   then the Servlet should compile just fine   You can specify a class path to use when you run javac exe as follows   d  javadev  javac -classpath    d  Program Files Apache Group  jakarta-tomcat-3 2 3 lib servlet jar  MyServlet java  Or in Linux javac uses   instead of    server1  javac -classpath      servlet servlet jar  MyServlet java
