ClassCastException: javax.servlet.http.NoBodyResponse

Hi all,
I Have an EAR containing a web application containing a bunch of servlets and an applet accessed through jnlp. When I start the applet, everything works perfectly well, all the functionnalities work. But in my log file, I get about 4 exceptions (always the same) and sometime later on (using the applet) I get one or two more. I know some people on the net had the same problem in various situations but I never found replies to their posts in the archives.
So it runs on sun JSAS 9.0, Windows XP64.
This is the exceptionx I get in the server log just when webstart starts:
(sorry, it is long and ugly in this small text box).
--> The "com.zerobase..." line is just because I override service() and call super() there.

ClassCastException: javax.servlet.jsp.jstl.fmt.LocalizationContext

today i had the following exception, which blows my mind away. what can be wrong?
java.lang.ClassCastException: javax.servlet.jsp.jstl.fmt.LocalizationContext
     at org.apache.taglibs.standard.tag.common.fmt.BundleSupport.getLocalizationContext(Ljavax.servlet.jsp.PageContext;)Ljavax.servlet.jsp.jstl.fmt.LocalizationContext;(BundleSupport.java:127)

well the fact is that the JSPs are 100% correct. i'm migrating some legacy project, which builds, deploys and runs in its old state with no errors at all (and the old state is current PRO, so every bit of code is supposed to be correct). hence i presume it's not the JSPs that are wrong (because i never touched them), that's something else, probably the configuration of things, or conflicts between container libs and webapp libs, or sort of like that.
so if this error doesn't ring a bell, then i'll try to fiddle around, i thought maybe that's something "famous" :).

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.

Javax.servlet.http.* package does not exist ?

i am using j2sdk which does not include servlets, so in the forums i found that including servlet.jar file in jdk1.6.0\jre\lib\ext javax.servlet.* was included but javax.servlet.http did not ..... now this is strange either both do not work or both work. here is the code
import javax.servlet.*;
import javax.servlet.Http.*;
class login
error is package javax.servlet.Http.*; does not exist.

Dear,
javax.servlet is one of the J2EE (Java Enterprise Edition) packages that is not included in the J2SE (Java Standard Edition) , so that one used for developing server side application.
I hope this help.
Regards.

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 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
http://jakarta.apache.org/tomcat/index.html

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...

Good luck,

Try giving servlet..jar path in the class path variable

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.

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 javax.servlet.http.HttpSessionListener 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:
The error is: com.sap.engine.frame.core.load.SAPNoClassDefFoundError: javax.servlet.http.HttpSessionListener

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