"javac blahblah.java" returned with error: package javax.servlet.http does,

and a bunch of "cannot resolve symbol".
I do have servlet-api.jar in the classpath.
This is ApacheTomcat 5.5.25, JVM version 1.5.0_04-b05,
javac -J-version
java version "1.4.2_13"
What am I missing?

The environment variabele $classpath is only used by the java runtime, not by the java compiler.Are you certain of that Balusc?
Granted I don't use the command line to compile things much, but I'm pretty sure it uses the CLASSPATH environment variable if you don't specify a -cp or -classpath.
Can you please show the
- error message/stacktrace
- value of CLASSPATH environment variable
- command line you are using to compile the class
- an excerpt from the class itself.
Cheers,
evnafets

Hi,
The file servlet-api.jar / servlet.jar is not available in your classpath.
To compile an Servlet you need the jar file to be in classpath.
The jar file can be found in your webserver / application server lib folder.

Zack

Package javax.servlet.http does not exist

Hello All,
A few problems here
1. My classpath doesnt seem to work.:
.;"C:\Program Files\Apache Software Foundation\Tomcat 6.0\lib\servlet-api.jar"
2. As a result, i get many errors in my simple code, but there are still a few that are not related to javac not recognizing the servlet api.
I also tried setting the classpath at the command line (event hough its temporary)
set classpath="C:\Program Files\Apache Software Foundation\Tomcat 6.0\lib\servlet-api.jar"
but the servlet package is still not recognized
I have 2 classes, one to read the database connection details from a file and another class, my servlet.

Package javax.servlet does not exist, package javax.servlet.http does not

Dear All,
I am a newbie to JAVA.
I installed JDK1.6.0_04, then NetBeans IDE 6.0
I tried compiling an example servlet, but got this error message:
package javax.servlet does not exist, package javax.servlet.http does not exist
I tried locating these packages, but in vain. I also tried setting the CLASSPATH to many values, still it did not work.
Can anyone, please, help me with this.
Should I be able to see/locate these packages, do I have to download them?
Thank you very much.

What servlet/JSP engine do you plan to deploy to? Tomcat, perhaps?I think it's Tomcat (C:\Program Files\Apache Software Foundation\Apache Tomcat 6.0.14). Are there other engines that come with NetBeans IDE 6.0 (when I downloaded NetBeans, I chose ALL)
>
If so, you'll need to put the servlet JAR in your CLASSPATH. (servlet-api.jar for Tomcat 5.5 and earlier, servlet.jar for 6.0 >and later.)
I tried locating these packages, but in vain.
You won't find them until you realize that you have to deploy that servlet someplace.How to deploy?
I also tried setting the CLASSPATH to many values, still it did not work.
See above. What were you planning to set CLASSPATH to?First I set to:
C:\Program Files\Apache Software Foundation\Apache Tomcat 6.0.14\lib (because I found jar named servlet-api.jar in this folder)
Later I added this:
C:\Program Files\Java\jdk1.6.0_04\lib (out of trial-and-fail)
Finally I added some paths that lead to a library such as
C:\Program Files\glassfish-v2\lib
C:\Program Files\glassfish-v2\lib\ant\lib
Can anyone, please, help me with this.
Should I be able to see/locate these packages, do I have to download them?
You have to get a servlet/JSP engine. Step 1.Thank you for your help

Package javax.servlet.http does not exists

Hi,
I am new to J2EE and am writing my first servlet. I tried to compile a servlet I wrote and got the following error.
"package javax.servlet.http does not exists".
What do i do to correct this error?
Also is there any links which has a complete servlet tutorial.
Please advice
Thanx

Most probably you need to include the servlet-api library in your classpath when compiling.
You should find this file in the lib directory of your container.
It will be called servlet-api.jar (Tomcat) or j2ee.jar (Suns J2EE server) or something along those lines.
The j2ee tutorial is a decent place to start learning about servlets...

Problem: package javax.servlet.jsp does not exist

I am a novice JSP programmer. My projects that use any javax.servlet classes are not seeing those at all. I am working with a group of folks using Java SE 1.5. (Note: I'm using Windows so the directory separator is "\")
What Used to work:
1. Nearly all my projects were working using Java version 1.6. These projects were developed as examples from Wrox and Apress books about JSP and Struts.
What has changed:
1. I un-installed the version 1.6 of JDK and JRE, as well as tomcat, netbeans, and all the associated libraries/jars.
2. I installed version 1.5 of JDK and JRE, as well as tomcat, netbeans, and all the associated libraries/jars.
3. I updated my JAVA_HOME, CATALINA_HOME, CLASSPATH, and PATH environmental variables. I made sure that the path to servlet-api.jar (in the tomcat common\lib) is included in the classpath.
What is wrong:
1. References to javax.servlet.* are not satisfied--they are flagged in the source code in NetBeans and I get compiler errors with any project containing those references. For example:
... package javax.servlet.jsp does not exist
import javax.servlet.jsp.*;
What I've found:
1. My CATALINA_HOME=C:\Java\Tomcat 5.5
2. My JAVA_HOME=C:\Java\jdk1.5.0_11
3. My CLASSPATH=.;C:\Program Files\QuickTime\QTSystem\QTJava.zip;%JAVA_HOME%\lib;%JAVA_HOME%\jre\lib;%JAVA_HOME%\lib\jsp-api.jar;%CATALINA_HOME%\common\lib\servlet-api.jar;C:\Java\logging-log4j-1.2.14\dist\lib\log4j-1.2.14.jar
4. My PATH=c:\wint\BIN;%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin;%CATALINA_HOME%\bin;C:\MySQL\MySQL Server 5.0\bin;D:\MiKTeX 2.5\miktex\bin;C:\Perl\bin\;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\QuickTime\QTSystem\;C:\Program Files\Microsoft SQL Server\80\Tools\Binn\;C:\SFU\Perl\bin\;C:\SFU\common\;C:\Program Files\Lahey-Fujitsu Fortran\v7.1\Bin;C:\Program Files\Lahey-Fujitsu Fortran\v7.1\Win32\Bin
What I need:
1. I need to have some reference to the servlet classes satisfied in my configuration. Any help is appreciated.
thanks
jondr

Oh. I got some over-the-shoulder debug help.
My error was in the classpath specification:
The path: %JAVA_HOME%\lib\jsp-api.jar
Should be: %CATALINA_HOME%\lib\jsp-api.jar
That contains the javax.servlet.jsp.*
Thimk.

You need a J2EE implementation, I recomemend Tomcat, you also need to put the .jar w/ the implementation in in your classpath.

servlet-api.jar is the jarfile that contains javax.servlet.ServletException and javax.servlet.http.* which are imported by WebTest.java and must therefore be found in the classpath. If javac doesn't find this jar (or the javax.servlet packages), it will say (or shout, depending on my and javac's mood): [the error message]
well...I set in the classpath the location of the servlet-api.jar
(found at: C:\Tomcat\common\lib)
I set it with the environment variable (windows xp)
Just as it's shown here: http://www.cs.usask.ca/~wew036/latex/env-env.jpg
NOTHING :-(
could anyone assist, thanks

Hi..seems u r new to J2ee.. dont worry its a very small problem:
Here is the solution.. yes u have to edit the environment variables:..
I am using J2EE sdk 1.4 and running on xp
This is the classpath setting:

This is the PATH setting

Error 500: javax.servlet.http.HttpSession: method getServletContext()Ljavax

I think that I have an older version of servlet class files... is there any way to solve the following issue?
in old version, getServletContext() method isn't included in HttpSession object. is there any way to get around this problem? cuz our client has an old version... i am not sure if it's possible...
HttpSession session = e.getSession () ;
// Retreive our context so we can initialize the runtime settings.
ServletContext context = session.getServletContext () ;
i'd greatly appreciated in advance...

sorry, in e.getSession(), "e" object comes from "HttpSessionBindingEvent"

When compiling servlets etc, you need to include in your classpath a jar file with all the javax.* classes defined in it.
For Tomcat this is called servlet.jar and is in (I think) [TOMCAT_HOME]/shared/lib or /common/lib
For J2EE 1.4 Server, the jar is [J2EE_HOME]/lib/j2ee.jar
Where the _HOME directory is the directory where you installed J2EE.
Include this jar file in your classpath when compiling.
Good luck,

I am suggesting that you need to read the documentation about the product(s) and set them up the way they require, rather than blindly think that the CLASSPATH environment variable is some magical entity.
I will try this, but I was hoping that since my IDE auto configured (with exception to java_home) that I would not have to do this. I wil give it try....thanks for the suggestion.See, you're using an IDE. Like I mentioned, IDEs do not use the CLASSPATH environment variable. You need to set up your project in your IDE in such a way that it knows what the dependent jars are. I'm sure there's a way to add jars to your project's dependencies.

Javax.servlet.http.* error

I am trying to compile a file, but got the error message "package javax.servlet.http does not exist",
"import javax.servlet.http.*"
It seems to me that this particular package is missing. how and where exactlly do I get this particular package and make it to work??
thanks

As you are using the package I assume that you're targetting a servlet engine (such as Tomcat) or a J2EE server. The package is in servlet.jar which is part of the binary release of the container that you are using.
You can download containers from the following links:
http://java.sun.com/products/servlet/index.html
