hi,
if you are using tomcat 5.5 server use jdk1.5 and if you use tomcat 5.0 use jdk1.4 then compatability adjust.And jar files to library go to tomcat-home ->common->lib->Servelet-api.jar file to your java program library.....
And better to use myeclipse1.4 instead of eclipse ... bcoz sometimes it requires plugins to avoid that use myelipse1.4 ......

import java.io.*;
public class HTTPGetServlet extends HttpServlet {
     public void doGet(HttpServletRequest request,
               HttpServletResponse response)

          buf.append("</TITLE></HEAD><BODY>");

On a closer look i realized that the IDE is showing as error any import statements i type in. Can anyone help me get over this problem? Thanks a lot in advance.

You need to add the JAR containing the servlet API in the external JARs for the project.

Please help me.....

Have a look in eclipse in the menu under window -> preferences -> java -> installed jre's which one is selected there.
Than you have to check you project settings: right click on the project and select properterties. Check "Java Build Path" and "Java Compiler" settings.
If you run your program, the console also shows the version you are running. If it is an 1.6 version everything should work.

How to run the simple java card program in eclipse?

I am trying to run a simple HelloWorld program in eclipse 3.5 having java card development kit 2.2 installed in it.
Firstly,I go to the JCWDE tab and press start..then when trying to deploy that package its giving me error like " com.hw.HelloWorld: unsupported class file format of version 50.0." can any one help me in this what is this error???n how to resolve n run this program..

Hi,
It is because the converter works on byte code and it only supports a subset of the Java language (see the JC specifications). It is kind of like compiling you code on Java 6 and trying to run it on Java 5. The JCDK outlines the required compiler version.

it's not CLASS_PATH, it's CLASSPATH.
Directory paths with spaces in them are problematic. Surround them with double quotes.
I think the best thing is not a CLASSPATH environment variable. Better to use the -classpath option on javac.exe when you compile.
So your command to compile might look something like:
javac -classpath .;"C:\Program Files\Tomcat\jakarta-tomcat-5.0.28\common\lib\servlet-api.jar" *.java%

Unable to run Servlet program using J2EE SDK

Hello,
i am a newbie to all this j2ee stuff and servlets even.so the problem that i have maybe a very common one and i hope that most of you may have a fix to it...
i use J2EE SDK to compile and run Servlet programs.I have a Servlet program with the class name defined as
public class MyServlet extends HttpServlet ....
the file is stored as MyServlet.java
i set the CLASSPATH variable so that the required classes for the compilation of the program can be located.
the program compiles without any glitches.
However when i run the program by saying
java MyServlet
( i dont think its any different to run servlet code is it?)
i get the message
java.lang.NoClassDefFoundException:MyServlet
Can someone suggest a remedy?
thank you
-NDK

First, I don't understand what you are trying to do. Running a servlet ?
Servlets are ran by an application server ! (Apache Tomcat ....).
Second, is your class in any package ?
