This blog post will help you if you notice that the javax servlet package does not exist. Javax package. Servlet. Javax file. A servlet package contains a set of classes and interfaces that summarize and define the contracts between the corresponding servlet class and the runtime provided by the servlet container corresponding to the instance of that class.

Well, these one or two packages are not actually built into Java like java.io. Instead, they come bundled with a servlet-centric web server (like Tomcat). First of all the Java compiler will be able to use our compiler servlet, we need to tell it where to find the types in these two packages.

The required classes are, of course, usually stored in a statement called servlet.jar. The exact location of this file will probably depend on the web server you are using, but in this case with Tomcat you can find it in any lib subdirectory of the main Tomcat build directory (for example, d: Program Files Apache Group jakarta-tomcat- 3.2.3 lib servlet.jar). In order for one of our Java compilers to compile servlets, you need to add this path to your Java classpath. As an extension, Java only looks for classes in the current directory (“.”). Where, “.” this is the standard classpath. If you change the contents of the servlet.jar document classpath (“.; D: … lib servlet.jar” on Windows, “.: / Usr /…/ lib / servlet.jar” on Unix), then the servlet should often compile well.

You can also specify the path for the class to be used when javac.exe is run as follows:

You must add a Tomcat parameter to your /lib/servlet-api.jar file to round up the classpath time.

  javac -cp.; / n / To / Tomcat / lib / servlet-api.jar com / example / MyServletClass.java 

The classpath is now where Java should look due to imported dependencies. Otherwise, it defaults to any current directory containing once. in the above example. ; is the partitioning path for Windows; If your site uses a Unix-based operating system, your company should use : instead.

If you are still facing the same compilation error and are currently using Tomcat 10 or newer, at this point you should migrate the latest imported sources from javax . * in Jakarta. * .

  import jakarta.servlet. *;jakarta.servlet.http. * import;

• jakarta.servlet.ServletException: class [com.practice.MyServlet] is not a servlet

If you are working with an expert project, add the following to your personal pom.xml dependency

       javax.servlet      javax.servlet-api      3.0.1      provided  

Well, these two sentences are not actually embeddeds in Java, as usual in java.io. Instead, they link to a servlet-compatible web server (like Tomcat). So, before the Java compiler can summarize our servlet, we need to figure out where to find the classes in these two packages.

The required classes are usually reserved in a servlet file named .jar. The correct location for this file depends on the theme of the particular web server software you are integrating into the game, but in the case of Tomcat clients, you can find it in the lib subdirectory, which points to the game’s main web directory. .. installing Tomcat. (e.g. d: Program Files Apache Group jakarta-tomcat-3.2.3 lib servlet.jar). In order for the Java compiler to compile the servlets, you may need to add this file to your personal Java classpath. By default, Java only looks for current free information (“”. “) To work with classes. Hence,”. “is the path of the rest of the class. If you change the path to the class, include it in the servlet file. Jar (“.; D: … lib servlet.jar “for Windows” .: / Usr /…/ lib / servlet.jar “for Unix) the servlet should compile correctly.

You can use almost any classpath if you can I can get javac.exe like this:

En / Example / Model / BearExtra.java

  package com.example.model;BearExtra public class public static empty go ()   System.out.It println ("yes, it works!");    

En / Example / Web / Bear.java

  package com.example.web;import com.example.model. *;Public class bear  static local community void main (String [] args)   BearExtra .go ();   

Now, to combine the race and these classes, go to the main directory where you can “see” and create multiple com folders:

* Nothing / MacOS

  javac -cp. com / example / model / *. java com / example / web / *. Javajava -cp. com.example.web.Bear 

Windows

  javac -cp comeexamplemodel * .java comeexampleweb * .javajava -cp. com.example.web.Bear 

  Yes, information technology works!

  Optional: thanks:

In my experience, I am not using an IDE and am trying to compile servlets myself from the command line.

I have assigned the following environment variables:
CLASS: C: Program Files Java jdk1.7.0 lib;CLASSPATH
: C: Program Files apache Foundation Tomcat 7.0 common lib servlet-api.jar; C: Program Files Apache Software Foundation Tomcat 7.0 lib commons-fileupload-1.2.1 .jar; C: Program Files Apache Software Foundation Tomcat 7.0 lib commons-io-1.3.2.jar; C: Program Files Java jdk1.7.0 bin; C: Program Files Java jre7 bin;

When I try to compile the servlet program, the following error literally pops up
