Getting javac to find javax.servlet package

Hey all. I'm trying to get Servlets to run on my computer. I'm using jdk1.4, it didn't have the javax.servlet package to start off with. I downloaded jsdk2.0, which includes the javax.servlet package. I can't get the javac compiler to find these classes no matter what I do, I copied the entire javax/servlet folder into the jdk1.4/src.zip file that seemed to have all the other import files, I copied the jsdk.jar file into jdk1.4/lib/ folder, that didn't work either. In my batch file that sets the path for jdk, I added set classpath = c:\jsdk2.0\lib\jsdk.jar and that didn't work. I really can't seem to get javac to find these classes. Any help is greatly appreciated!

The above advice is incorrect and can lead you to many problems.
You should have nothing in your CLASSPATH environment variable immediately after installing J2SDK 1.4.1.
You then have to install the Servlet API by pointing your CLASSPATH env. var. to it. To do this depends on the version of the Servlet spec. that you have as some of the olders ones were distributed as jar files, and the latest I believe is a set of classes to be extracted.
At the end of the day, you must point your CLASSPATH to the Servlet API. Read up on how to set the CLASSPATH. Also, don't forget to include the current working directory (.) in your CLASSPATH after manually setting it.
Good luck !!

Javac cannot find javax.servlet.*; package

getting an error when I try to compile code that contains the line:
import javax.servlet.jsp.*;
import javax .servlet.*;
Yet, other classes in javax can be seen by the compiler such as javax.swing.*;

I had to download the servlet specification from sun as it wasn't in my jdk (I prefer stripped down versions). Then I placed the jar file in my classpath.
Alternatively, if you are already running tomcat you can point to the servlet api jar file in the lib directory.
And a clear indication that the person stumbling like
that shouldn't try writing servlets yet, as he
clearly lacks knowledge about what's even in the
standard API and what isn't.That's a clear indication that the person making such comments should not be on the forums as the idea is to help people and encourage people.

Cannot find javax.servlet package

I have just downloaded and installed the latest JEE SDK having installed Tomcat on a Linux box so that I can start getting to know JSP.
I am following an example in a book I have for this Servlet...
import javax.servlet.http.*;
import javax.servlet.*;
import java.io.IOException;
public class BasicServlet extends HttpServlet {
     public void doGet (HttpServletRequest req, HttpServletResponse res)
          throws IOException {
          ServletOutputStream out = res.getOutputStream();
          res.setContentType("text/html");
          out.println("<html><head><title>Basic Servlet</title></head>");
          out.println("<body>Hello World</body></html>");
I am using Textpad to write and compile my java and when I try to compile I get errors basically saying that it cannot find the first 2 packages I am trying to import (it manages to find the IOException fine)
Any ideas why? I suspect that the servlet package is not in the classpath but I do no know where the package is in order to add it to my class path.
many thanks

I cannot find javax.servlet package in j2sdk-1.4.0-beta3

I just download and install j2sdk-1.4.0-beta3 and progam a very simple program use import javax.servlet.* and compile it, there is a mistake:
package javax.servlet.* does not exist
And I check the doc of j2sdk-1.4.0-beta3,I also can not find package javax.servlet.So where could I find this package? Need I configure somewhere or download another products?

Hi,
You can go to http://java.sun.com/products/servlet/download.html,
download the servlet 2.3 class files, add the zip file to the classpath.

Javax.servlet package

hi i am using netbeans but i want to deploy some servlets in my mobile application but i am getting problem in accessing javax.servlet package. can anyone tell me where can i get this one. my application is stuck now ......plz reply me fast...... i search a lot i got the specs of it but not the api.

I wonder what you're trying to do.
In my case, I have installed Tomcat 5.0. This installation included a jar file containing the different servlet classes I need to develop servlets. This jar file is in the folder C:\Program Files\Apache Software Foundation\Tomcat 5.0\common\lib.
I did not need to move the jar files from Tomcat to the folder of my J2SDK.
But I had to add en environment variable under Windows XP, namely CATALINA_HOME to let the computer know where the folder of Tomcat was. With this variable, the jar file containing the classes for servlet programming can be found.

How do I get the javax.servlet package?

I have a simple question. I downloaded the JAVA platform Standard Edition SDK 1.6.0 and find that it doesn't have the javax.servlet package? From where can I get it and how to install and configure?

hi,
you don't have servlet in J2SE... you can get it
from J2EE ... download the latest J2EE .. the
package is available in j2ee.jar file..
ou can download it from:
http://java.sun.com/javaee/downloads/index.jsp
-- Abdel Raoof Olakara
http://olakara.googlepages.com
You are quite wrong my friend... Servlets don't depend on any J2EE container, the only thing you need is a J2SE edition... check this:

How to get javax.servlet package

Hi guys
Does anybody know how to get javax.servlet package?
Thanks in advance.
Regards,
Mark.

I just moved the servlet jar into java_home/jre/lib/ext and I made some progress. Instead I recieved this error
---------- Javac ----------
Note: C:\jdk1.3.1_04\bin\java\lang\ThreadGroup.java uses or overrides a deprecated API.

Compiling Servlets: javax.servlet package unknown

Hello everybody,
I'm new to J2EE technology and would like to start with creating servlets, but the javac compiler can not compile my java class succesfully, cos' it seems, it does not know the javax.servlet package.
In each documentation is just a sentence: run javac ... But it does not work.
Do I have to have some special configuration? I also downloaded the J2EE SDK, but the problem resisted.
Help me, please!
Thanx, Peter

Hi peter,
If you have installed the J2EE SDK 1.4, you would find $INSTALL_ROOT/lib/j2ee.jar (INSTALL_ROOT means the installation directory of J2EE SDK). PLease keep this j2ee.jar in the classpath and compile, things would be fine.

Development kit which includes the javax.servlet package

Which java development kit(s) contain the javax.servlet package.v I can't seem to find one. Thanks

You might want to ask this on the Java forum - but if you want to run a servlet you need a Java EE server - something like Glassfish or WebLogic or Tomcat.
The Java forums are here:
https://forums.oracle.com/forums/category.jspa?categoryID=285
Right now you are in the JDeveloper forum - and by the way, if you download JDeveloper you'll get everything you need to develop and test run your servlet.

Cann't find javax.servlet.*

Hi there!
I cann't compile a servlet by means of ant...
It cann't find javax.servlet.*
I've searched for it in jakarta-tomcat-5.0.18 directory but didn't find anything...
Where is it situated?

It should be in %CATALINA_HOME%/common/lib/servlet.jar or %CATALINA_HOME%/common/lib/j2ee.jar

Can't find the servlets package when compiling

Hi,
My problem is that when I compiling my servlets so can't the compiler find the two packages javax.servlet and javax.servlet.http.
Why?
Please can someone help me with this problem!
HelloServlet.java:2: package javax.servlet does not exist
import javax.servlet.*;
^
HelloServlet.java:3: package javax.servlet.http does not exist
import javax.servlet.http.*;

OK,
It seems like it will work with your proposal to. But now I have a new problem that you maybe can solve for me. That is when I try to test the following (from the book More Servlets and JavaServer Pages):
Test 3: A Servlet That Uses Packages and Utilities
The final servlet you should test to verify the configuration of your server and development environment is one that uses both packages and utility classes. HelloServlet3.java is a servlet in the moreservlets package that uses the ServletUtilities class to simplify the generation of the DOCTYPE (specifies the HTML version--useful when using HTML validators) and HEAD (specifies the title) portions of the HTML page. Those two parts of the page are useful (technically required, in fact), but are tedious to generate with servlet println statements.
Since both the servlet and the utility class are in the moreservlets package, they should go in the moreservlets directory. If you get compilation errors, go back and check your CLASSPATH settings--you most likely forgot to include the top-level development directory. I've said it before, but I'll say it again: your CLASSPATH must include the top-level directory of your package hierarchy before you can compile a packaged class that makes use of another class from the same package. This requirement is not particular to servlets; it is the way packages work on the Java platform in general. Nevertheless, many servlet developers are unaware of this fact, and it is one of the (perhaps the) most common errors beginning developers encounter.
Once you compile HelloServlet3.java (which will automatically cause ServletUtilities.java to be compiled), put HelloServlet3.class and ServletUtilities.class in install_dir/webapps/ROOT/WEB-INF/classes/moreservlets. Then, access the servlet with the URL http://localhost/servlet/moreservlets.HelloServlet3. You should get a simple HTML page that says "Hello (3)".
This works not for me! I will get this message when I try to compile HelloServlet3.java:
C:\Apache-Tomcat-4.1.27\ServletsDevel>javac HelloServlet3.java
HelloServlet3.java:23: cannot resolve symbol
symbol : variable ServletUtilities
location: class moreservlets.HelloServlet3
out.println(ServletUtilities.headWithTitle(title) +

Tomcat 5 can�t find javax.servlet.http.HttpServlet

Hi.
I don�t know if this is a simple question or not, but i didn�t find anything solving this problem and
i�m new to tomcat......
I�m trying to deploy my web application in my system. (Windows XP , j2sdk1.4.2_02, jakarta Tomcat 5, jakarta struts 1.1 and jakarta taglibs 1.1).No problems while compiling the .java classes and checked all the .jar files that my application needs to work (or that is what I think). I expand my .war file at /webapps on tomcat directory and startup Tomcat. Tomcat starts up but while starting I get the following errors...

"...The CLASSPATH is ignored by Tomcat, of course. AND javac. AND java. AND Eclipse. AND NetBeans. AND JBuilder. And just about everything else in the Java universe..."
What I mean by this, of course, is that each of these requires you to set the CLASSPATH in the way they expect. None of them even looks for a system environment variable named CLASSPATH. You can waste a lot of time thinking that your CLASSPATH is "all set", but it's not.
Tomcat assumes the following for your Web app's CLASSPATH:
(0) The JDK rt.jar, of course,
(1) All the JARs in TOMCAT_HOME/common/lib,
(2) All the JARs in your WEB-INF/lib,
(3) All the .class files in your WEB-INF/classes
That's it. (Maybe one or two others, but those are the important ones.)
Eclipse and NetBeans have their own way to set CLASSPATH for each project. You'll have to learn how for those IDEs.
The CLASSPATH is still vitally important. The system environment variable just isn't part of it. - MOD

Cannot find javax.servlet in J2EE

I am learning about servlet programming. I am using JBuilder-student edition. I downloaded J2EE. I changed the project properties in JBuilder to use the java.exe in J2EE, but when I try importing javax.servlet or the like, it does not show that javax has such a package. Please help. I am working on this project with a professor, and I have to show some work done soon! I cannot get started with my work unless I get javax.servlet.
I hope somebody can help me.
Thank you,

It seemed that the installation did not unzip the j2ee.WAR, which contains the servlet stuff.(or is it not supposed to?) I then added the folder j2ee to the class path, and it works. I am dumb enough not to understand how it worked, could someone explain please.
Thank you
