Javax.servlet.* and javax.servlet.http.* don't exist???????

When I compile a class that hase the following import statements:
import javax.servlet.*;
import javax.servlet.http.*;
the compiler says that those packages don't exist, but I'm pretty sure that the do.
Does anybody knows what I could do wrong?

I am having the same problem. I have downloaded both jdk1.3.1_02 and j2sdkee1.3.1. I updated both my Path and CLASSPATH variables to include the path to the jdk1.3.1_02 bin, lib, and jre directories ... as well as the j2sdkee1.3.1 bin and lib directories. Isn't the javax.servlet package included with the j2sdkee installation? I had this working on a different machine a while back, and I'm almost certain these are the only downloads I had.

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.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...

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

Cannot Import javax.servlet.* and javax.servlet.http.*

Hello,
I am a University Student and now doing a project using Servlet and JSP
I have installed WinXP and Tomcat 5.0 on my computer
When I compile the servlet , there are error messages "package javax.servlet does not exist" and "package javax.servlet.http does not exist" coming out.
I have set the classpath already
i.e. %CATALINA_HOME%\common\lib\servlet-api.jar;%CATALINA_HOME%\common\lib\jsp-api.jar
( Of course "%CATALINA_HOME%" = my folder that install the Tomcat )
Can Anybody Explain what is happening and suggest a solution to me?
Please give a hand.

When you ran that command, what happened? Let javac.exe tell you the right answer.
I'd advise two things:
(1) Installing any s'ware in a directory whose name contains spaces (e.g., "Apache Software Foundation" or "Tomcat 5.0") is a very bad idea, IMO. I'd reinstall to a new directory.
(2) Your HelloServlet.java servlet probably doesn't have a package statement in it. Tomcat 5.0 won't play nicely with servlets or beans that aren't in packages. I'd add one and use the -d . option on javac.exe to make sure it created the package directory structure for me.

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

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

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).

tomcat�s web applications servlets-examples and tomcat-docs work fine, but my application doesn�t. Is there any relation between those errors? any idea about what happens?
Thank you in advance.

"...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

How to import javax.servlet.http.*

Dear all,
I'm trying to create an applet that writes (and later reads) a cookie from the clients local HDD. The first thing I run into is that I'm unable to import the nessecary class, which would be, I think, "javax.servlet.http.cookie". I'm using JBuilder 8.0 and every time I'm typing "import javax.servlet"
I get the message "cannot acces the directory "javax.servlet".
How should I troubleshoot this problem?
Regards Ronald

Dear Myself,
I solved the trouble. What I have done is I downloaded the enterprise 1.4 SDK and added the j2ee.jar to the JBuilder 8.0 JDK directories.
Problem solved.
Yippie....
Bye.

While running my app I get the below error - have different Class objects for the type javax/servlet/http/HttpServletRequest used in the signature

I am running ATG[10.1.2] app on Jboss [EAP 5.1.0 GA] I am able to open dyn/admin however when I start my app I get the below error

The supported JBoss version for 10.1.2 is JBoss EAP 5.1.2 but I don't think that your issue is caused because of this. Your issue is more of an environmental thing as you are probably getting two different versions getting loaded of class javax.servlet.http.HttpServletRequest and so correspondingly two different Class objects as the error shows. One reason for this could be if you include any server-specific libraries (in present case the Servlet API JAR which contains the class javax.servlet.http.HttpServletRequest) of a different version in the /WEB-INF/lib of your web application. Try removing it from there if so and see if that helps.

SAPNoClassDefFoundError: javax.servlet.http.HttpSessionListener

Hi,
I have deployed an application in to Netweaver WAS, and have given a hard reference to one of the libraries which is already deployed in the same server. But when starting the application, it gives an error telling that <b><i>javax.servlet.http.HttpSessionListener</i></b> is not available. I gave the servlet.jar in the classpath and still its giving the same error.
Can anyone tell me what can i do to get rid of this problem? This is the error message iam getting in the defaulttrace file:
<b><i>The error is: com.sap.engine.frame.core.load.SAPNoClassDefFoundError: javax.servlet.http.HttpSessionListener</i></b>

Hi Venkat
Check in the visual admin-deploy service,whether or not your application is deployed.Try to start it.
Also check out the below link
