How to compile a servlet

I am trying to compile a servlet using the import javax.servlet.*;
import javax.servlet.http.*; packages. But the only thing I keep getting is :
BasicServlet.java:1: package javax.servlet does not exist
import javax.servlet.*;
^
BasicServlet.java:2: package javax.servlet.http does not exist
import javax.servlet.http.*;
^
BasicServlet.java:6: cannot resolve symbol
symbol : class HttpServlet
location: class BasicServlet
public class BasicServlet extends HttpServlet
I have included the servletapi2_1_1-win package from the sun site containing the servlet.jar in my classpath. Still it refuses to compile. Besides does anybody know how to compile using the servlet packages available in Tomcat or j2ee, both of which I have on my machine , but can't figure what to include.
Please help.
^

have you actually included the servlet.jar file in your classpath or just the directory, as you need to explicity declare jar files in the classpath...
javac -classpath %CLASSPATH%;C:\[servlet-jar-path]\servlet.jar Servlet.class

Download j2ee is recommended to solve any compling such as servlets and swing
http://java.sun.com/j2ee/download.html
Once done all you do is include j2ee.jar and you have xml, servlets, rmi the works!! :)
However since you download the servelet component only, search in you hard drive for ".jar" file.
You can open the .jar file with a WinZip and you can check if it as javax.servlet.http.* by looking at the far right for javax/servlet/http
Once you know the jar file to include. Next is to put it in the classpath. The most simple way using NT example, how Windows 95/98 is similar. Go to:
Control Panel -> Double Click on System -> Click on Environment tab
Type below in Variable: CLASSPATH
Type in Value: PATH TO SERVLET;.;
Don't forget the ;.; (the dot for currnet path to run)
If you need to add more to the classpath, seperate by classpath.
Log off and log back in as your user. No need to reset the machine.
The system will pick the new CLASSPATH.
Test on dos as "echo %CLASSPATH%" to see what its set to.

How to compile and run a Java servlet using the BEA weblogic server

          Hi,
          Could you help me out as to how to compile a servlet using Web Logic server.I have written a Servlet program and have also set up the environment in the "c:\bea\wlserver6.0\config\examples" folder by giving the command setExamplesEnv.cmd.
          I have stored my GreetingServlet.java file in "c:\bea\wlserver6.0\samples\examples\servlets" folder.

Hello,
1. The .form file was used by Netbean's GUI builder to create the .java and is not needed for compilation.
2..../src # javac -classpath "..." mytool/*.java
I guess the package mytool was not coped with.
Alternatively it is worth to use the ant build tool also used by Netbeans.
Then you can make a jar from the class files, indicate in the manifest.mf file:
1. the main class
2. the library jars

You can compile your servlet as you do for ordinary classes.
like
javac servletfile.java
but do check before you compile that, your servlet.jar or j2ee.jar is there in class path or not.
after compilation put your servlet class in the classes dierectory of your Webserver.

Here is what you will need to do.
1. Compile the servlets by performing the following steps
1.1 Open a command line in the directory where your servlets are located.
1.2 Type the following commands
1.2.1 javac GreetingServlet.java
1.2.2 javac ResponseServlet.java
Then you should see the .class files for these classes appear in the directory .
Next you will put these class files in the WEB-INF/classes directory.
Once you have done that you will edit your web.xml in the WEB-INF directory to include the two servlets. That code will look something like this
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
"http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
<web-app>
     <servlet>
          <servlet-name>GreetingServlet</servlet-name>
          <servlet-class>GreetingServlet</servlet-class>
     </servlet>
     <servlet-mapping>
          <servlet-name>GreetingServlet</servlet-name>
          <url-pattern>/GreetingServlet</url-pattern>
     </servlet-mapping>
     <servlet>
          <servlet-name>ResponseServlet</servlet-name>
          <servlet-class>ResponseServlet</servlet-class>
     </servlet>
     <servlet-mapping>
          <servlet-name>ResponseServlet</servlet-name>
          <url-pattern>/ResponseServlet</url-pattern>
     </servlet-mapping>
</web-app>Once you have done this save the web.xml file and recompile the war file by following these steps
1 open a commandline in the root directory where the servlets are
2 type the following command jar -cvf warFileName.war .
*Note the space and period at the end of the command are not a mistake the space . tells the jar tool to complie the war from the directory you are current in.
Once this command is successfully ran you should see a .war file appear in the directory you are in. Then simply put the war file in your deploy directory of your server and you are finished.
alternatly if you are just doing this for yourself to learn servlets and this is not going to be deployed anywhere then I would just use the W3C's Jigsaw server which does all the work for you all you have to do is compile the servlets and put the class files in the servlets directory and you are done.

How to Compile Servlet Java Files

hello ...
i am a beginner at JSPs and java servlets ... i have been searchin' hopelessly for the past couple of days. Could someone please guide me on how to compile source files for servlets ... namely how can i include the packages javax.servlet.* since the compiler gives me an error that there is no class name ... I am using jdk1.3
Do I need to get the java server development kit ... but i cant seem to find it any where on the sun's site ... and do i need to download the j2ee sdk too ...
As you can gather that i am completely comfused and lost ... After doing programmin with asps and previous java experience, i had thought that the migration to a java platform on would be a breeze but the lack of any solid documentation which addresses the above questions is dampenin my spirits ... and the cryptic documentation with tomcat doesnt help either. :)
pleaze reply soon ... i have to implement a project for my company ... otherwise i would have to put servlets and jsp back in the closet and return back to asp.

Try http://java.sun.com/j2ee/docs.html specifically, the links on that page called Download Instructions, Installation Instructions, Java Servlets Tutorial and JavaServer Pages QuickStart Guide
By the way, J2EE SDK's reference implementation is based on Tomcat itself but is more than a web container.

How to Compile servlet files in weblogic

Hi,
I would like to know how i can compile the servlet files to deploy in weblogic.
I searched for servlet.jar or servlet-api.jar files in my weblogic 8.1 installed folder. Could not find it to set the classpath.
Please help.

You need to use weblogic.jar for Weblogic 8.1. It should be present under server\lib subdirectory in Weblogic installation directory.

}

heyall, just placed the following java code in my src folder in my web app folder in netbeans, anyone tell me how to compile this now?F9
it asks me for a main but not sure exactly what to putCompiling source files never 'asks .. for a main'. You must be trying to execute it. You can't do that outside the servlet container it is intended for
COMPILER ERROR - package javax.servlet.http does not exist
BUT can't even get this far yetSo try compiling it as per your tutorial. Do you understand the difference between 'compile' and 'run'?

How to compile servlet with Edit Plus?

Hi
I am writing a Java servlet in EditPlus and am wondering how to include the servlet.jar file so that EditPlus knows where the javax.servlet.*, etc classes are. I suppose this is an EditPlus specific question so sorry about that but I didn't know who else to ask other than EditPlus themselves of course and I think I have tried that once.
I have read replies on this forum about changing the classpath but I dont think that that is what I need to do here and if it is I dont know what I should be writing as I am not using the jdk.
If anyone can help me at all I would be very grateful.
Thanks

Yes, I have also compiled Java files from EditPlus. Using the facilities for configuring 'User Tools' in EditPlus.
EditPlus runts programs(javac in the current context) in a separate environment(separate DOS command).
I just compiled, from EditPlus, some Java file of mine that uses something from the servlet API. It compiled just fine. I did not do any classpath or other setup on classpath lines inside EditPlus. I guess, EditPlus inherits the existing CLASSPATH(all environment settings in fact) setting from your environment and thereafter aslo passes it along to the separate command prompt it opens to run user configured tools to run.

How to compile a java file(Servlet) in J2EE v1.3.1

This is my first time using J2EE instead of J2SE!!HOw to compile a java file in J2ee\bin because there is no javac in j2ee and when i compile in J2se i got
G:\j2sdk1.4.1_01\bin>javac HelloServlet.java
HelloServlet.java:2: package javax.servlet does not exist
import javax.servlet.*;
This mean it doen;t support servlet in J2se!!so how can /what command to compile a servlet java file in j2ee.Thanks

You'll need to add the j2ee.jar to your classpath. Usually you'll have to add some jars from your app server to your classpath as well.
For example (using weblogic):
javac -classpath c:\java\j2ee\j2ee1.3.1\lib\j2ee.jar;c:\tools\appserver\weblogic\wl7.1\lib\weblogic.jar
HelloServlet.java

How to compile and execute servlet file in j2ee

In j2ee server when iam compiling servet i am getting error messages like package javax.servlet,and javax.servlet.http does not exist like that.
i hsve set path like this.and i gave path for j2sdk .
set CPATH=.;%J2EE_HOME%\lib\j2ee.jar
javac -classpath %CPATH% AdderServlet.java
can anybody tell me where to place
servlet and how to compile it.
Thank u,
Renuga

Make sure that '%J2EE_HOME%\lib\j2ee.jar' is existing. Where is your J2EE_HOME pointing to?
The best thing I can suggest is, create your own bat file to compile the servlets. Like this,
Save the lines below as "MyCompiler.bat" file.
@echo off
set JDK_HOME=<path to you jdk home upto bin directory>
set J2EE_HOME=<path to you je22 home>
set CLASSPATH=.;%J2EE_HOME%\lib\j2ee.jar
%JDK_HOME%\javac %1
Use the command,
MyCompiler AdderServlet.java
You can improve this MyCompiler.bat further, can add additional jar files to the classpath whenever you want. You can put this bat file in System's path, so that you can invoke it just by the name (MyCompiler) without giving the full path to it (like C:\mydir\MyCompiler).
Hope this helps.

How to compile servlets

well,actually the problem arises this way.i have installed the new version j2ee sdk which even contains j2se1.5.now when i compile the servlet program it says the package import http.servlet.*; does not exists.i even had set the classpath as C:\Sun\AppServer\jdk\lib\dt.jar;C:\Sun\AppServer\jdk\lib\tools.jar;C:\bea\weblogic81\server\lib\weblogic.jar;C:\bea\weblogic81\server\lib\webservices.jar;.;
b'coz i m using web-server as weblogic so i even included it in the classpath.now wats the problem for compilation ,i tried all sorts of things but unable to solve.so plz some1 do post the solution as i m preparing for SWCD.

well,actually the problem arises this way.i have
installed the new version j2ee sdk which even
contains j2se1.5.of course - jee cannot exist without jse.
now when i compile the servlet
program it says the package import http.servlet.*;
does not exists.Because you need that package in your CLASSPATH and it's not, according to the compiler.
i even had set the classpath as
C:\Sun\AppServer\jdk\lib\dt.jar;C:\Sun\AppServer\jdk\l
ib\tools.jar;C:\bea\weblogic81\server\lib\weblogic.jar
;C:\bea\weblogic81\server\lib\webservices.jar;.;I'm confused - you have WebLogic 8.1 as your JEE server. Why do you need the one from Sun? (Answer: You don't.)
b'coz i m using web-server as weblogic so i even
included it in the classpath.now wats the problem for
compilation ,i tried all sorts of things but unable
to solve.so plz some1 do post the solution as i m
preparing for SWCD.You're preparing for SWCD and you don't know how CLASSPATH works? Oh, my.
You should not use a system environment variable CLASSPATH. (I don't have one.) Use the -classpath option on javac.exe and java.exe when you compile and run, respectively. You should set the CLASSPATH each and every time you compile and run, because it changes with every application you write.
If this becomes tedious, either put it in a script or learn how to use Ant.

How to compile servlet

Hi,
Now i create my first servlet, I want to compile and run it.
I downloaded J2EE SDK but I don't know where is the jar file which contain servlet classes.
thanks,
Shimaa

My friend , From your post it seems you have kickstarted your career in JSP and Servlet Technology. Compiling a Servlet is as simple as mud if you are using Tomcat [Best Server for Beginners in this field]
For Tomcat :
If you downloaded the tomcat server from Apache website and if you extracted to your c:\ , then following things have to setted up in the environmental variables of your machine (Right click Mycomputer ->Advanced->Environmental Variables)
1: CATALINA_HOME : C:\jakarta-tomcat-5.0.16
2:CLASSPATH : C:\jakarta-tomcat-5.0.16\common\lib\servlet-api.jar;C:\jakarta-tomcat-5.0.16\common\lib\jsp-api.jar
3:JAVA_HOME : C:\j2sdk1.4.0
4:path : c:\j2sdk1.4.0\bin;C:\jakarta-tomcat-5.0.16\bin..
Hope this helps...
