Creating a Servlet (javax.servlet.* & javax.servlet.http.*)

Hello,
I am writing my first servlet and I need to include the following 2 packages (javax.servlet.* & javax.servlet.http.*). I have J2SE & J2EE installed on my machine, but I am still unable to compile because I am missing these important packages. Perhaps I have a partial install or I need to get these from another site? I did look in my lib & bin directories and searched my all my hard drives. I would appreciate if some one can help me out.

You need to make sure that servlet.jar is in your classpath or that you add it to your 'java' argument list when compiling your files. So if you're using Windows you'd do something like:
c:\java -classpath c:\j2ee\servlet.jar MyServlet.java

  • 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.

  • 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). I expand my .war file at /webapps on tomcat directory and startup Tomcat. Tomcat starts up but while starting I get the following errors...

    it seems like C:\softProyecto\Tomcat5\conf\Catalina\localhost\admin.xml (C:\softproyecto\tomcat5 = tomcat�s home directory) needs javax.servlet.http.HttpServlet. And that comes from a Tomcat .jar file, i think.
    After more and more messages..... here it comes my application (MapasRuido)...which needs javax.servlet.http.HttpServlet and compiled ok at compiling time!

    "...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

  • Service method in javax.servlet.http.HttpServlet

    Hi All,
    I have a doubt in the service method of javax.servlet.http.HttpServlet
    There are two service methods in the javax.servlet.http.HttpServlet.
    one is with protected and other is with public access specifier.
    In the javadoc it is said that public service method dispatches client requests to the protected service method.
    Why this type of design is required.
    Instead of having a two service methods, Is it not possible to have a single service method and attain the functionality intended.
    Are there any advantages by having two service methods.
    I think there may be some idea/functionality behind these for having two service methods , which I am not able to understand.
    Would be greatful , if someone can throw light on this .
    Thanks,
    Dhanasekaran.

    This is just a theory, but here goes:
    The public service() method takes arguments of ServletRequest and ServletResponse, presumably because that's the signature that the non-HTTP specific servlet engine requires.
    The protected service() method of HttpServlet takes arguments of HttpServletRequest and HttpServletResponse and includes HTTP specific functions.
    My guess is that the public service() method either casts the arguments to the Http objects or does work to create the Http objects before calling the protected method.

  • 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.

  • Importing of javax.servlet.http.* ???

    I currently have a JSP page where I would like to remove someof the java script code and place within a processRequest mathod within the bean I am using. In doing so, I am assuming I need to import:
    import java.beans.*;
    import javax.servlet.http.*;
    import javax.servlet.*;
    In order to create a method such as:
    public void processRequest (HttpServletRequest request) {
    // Get the name and e-mail.
    this.processError = false;
    if (name == null) setName(request.getParameter ("name"));
    if (email == null) setEmail(request.getParameter ("email"));
    if (name == null || email == null) {
    this.processError = true;
    return;
    // Get the date.
    String dateR = request.getParameter ("date");
    if (dateR == null) date = JspCal.getCurrentDate ();
    else if (dateR.equalsIgnoreCase("next")) date = JspCal.getNextDate ();
    else if (dateR.equalsIgnoreCase("prev")) date = JspCal.getPrevDate ();
    entries = (Entries) table.get (date);
    if (entries == null) {
    entries = new Entries ();
    table.put (date, entries);
    // If time is provided add the event.
         String time = request.getParameter("time");
    if (time != null) entries.processRequest (request, time);
    I could then use something like this within my JSP page to handle the processing of the request to the JSP page:
    <%@ page language="java" import="cal.*" %>
    <jsp:useBean id="table" scope="session" class="cal.TableBean" />
    <%
         table.processRequest(request);
         if (table.getProcessError() == false) {
    %>
    My problem here is that the javax.servlet.* does not seem to be included within jdk1.3. Where can I find these so I can make use of them?
    Thank you!

    effectivly javax.servlet doesnot come with j2se 1.3 but you can download it here : http://java.sun.com/jsp (in subsection : "download reference implementation and specification")
    however i bet that it is provided with every servlet engine you could download...

    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.
    Regards,
    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,
