Package java servlet 2.2

i downloaded servlet2.2.zip, and i don't know how to deploy it. i want to use "import javax.servlet.jsp.*;" in my java program.
thanks in advance.

The zip may contain a jar perhaps called servlet.jar or if not then a number of class files.
Use WinZip or PkZip to extract the jar to a directory where you keep other jars, or if just classes then extract those to a directory.
If you use the environment variable CLASSPATH then adjust the script that sets it to include either the jar or the classes directory. And you're ready to go.
If you use a tool like JBuilder then create a library including the jar or classes directory.

it is because i have no one to look up at for help with java, except for the book (The Complete Reference, Java 2, 3rd Edition, Naughton & Schildt) and, of course, some times this forum.There's the whole Internet available to you. Remember, Google is your friend.
please, will anyone tell me how to find out what server type and version does JDK 1.6.0_10 provide? It doesn't. Java comes in three 'editions':
Micro (JME, earlier J2ME which is meant for mobiles and other similar platforms)
Standard (JSE, earlier J2SE which is what you're using, it's meant for core Java applications, like the sort you might use on your desktop.)
Enterprise (JEE, earlier J2EE which is for server side code. This includes JSPs, Servlets, EJBs etc)
i did not find any information about this in the book.Probably because it's a Java 'Standard' Edition (JSE or J2SE) book
What you need, to learn about servlets, is a JEE book. I'd suggest Head First Servlets and JSP from O'Reilly. Otherwise, follow the link I gave earlier to find tutorials.
To get started, you'll need a JDK, which you say you already have and a server. I'd suggest you get Tomcat. You will also find the servlet-api.jar after you setup Tomcat. This is an implementation of the JEE specification for servlets. This contains the javax.servlet.* packages you'll need to compile. Beyond this, the scope of what servlets are and how to deploy etc is rather large and best left to one of the afore-mentioned tutorials.

Problem Installing Java Servlets Package

I downloaded a sample servlet program which imports classes from the Java Servlets Package. I have the JDK 1.2 which does not come with the servlet classes (javax.servlet and javax.servlet.http). So I then downloaded them from java.sun.com. They come as a set of class files in .zip format. I thought packages were supposed to be in .jar format? At any rate, my compiler still fails to see these classes even after I have extracted these files into the same directory as the original .zip file and added this directory to my classpath. Am I going about this the wrong way? Any ideas on how I can make my compiler see these classes? --Thanks

I down loaded j2sdk 1.4 . and also down loade servlet package. I installed in bin directory.
i took the sample program and compiled. there is error message " java servlet package not found.
please help. email me at [email protected]
Thanks

When compiling servlets etc, you need to include in your classpath a jar file with all the javax.* classes defined in it.
For Tomcat this is called servlet.jar and is in (I think) [TOMCAT_HOME]/shared/lib or /common/lib
For J2EE 1.4 Server, the jar is [J2EE_HOME]/lib/j2ee.jar
Where the _HOME directory is the directory where you installed J2EE.
Include this jar file in your classpath when compiling.
Good luck,

You need to elaborate "not working" in developer's perspective instead of in user's perspective.

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.

Okay...I'm a seasoned programmer in every language but JAVA. Here's the issue...every time I try to use the Core Servlets book/website by Marty Hall and Larry Brown I get hung up on the packages.

You are then suggesting that I make the corrections directly to the files in apache using notepad instead of using the envir. variables?No I am not suggesting that. I am suggesting that you need to read the documentation about the product(s) and set them up the way they require, rather than blindly think that the CLASSPATH environment variable is some magical entity.
I will try this, but I was hoping that since my IDE auto configured (with exception to java_home) that I would not have to do this. I wil give it try....thanks for the suggestion.See, you're using an IDE. Like I mentioned, IDEs do not use the CLASSPATH environment variable. You need to set up your project in your IDE in such a way that it knows what the dependent jars are. I'm sure there's a way to add jars to your project's dependencies.

Inputting an excel file to the java servlet program

Hi,
How can I input an excel file into the java servlet program? I am using POI HSSF programming to read the content of that excel file.I have created a form that will accept the path from the user and in the servlet program, I have called a post method to retrieve the path of the file. I am getting the path of the file as a string.Then I have to access the file to read the data. But it is not working. What should I do?.Please help me.
I have created an html file to create a form that will ask the path of the file to be loaded into the servlet program.Please give me a solution,thanks in advance. The servlet program that receives the file is shown below. It just only take the name of the file and prints if that is ok.

Problem: package javax.servlet.jsp does not exist

I am a novice JSP programmer. My projects that use any javax.servlet classes are not seeing those at all. I am working with a group of folks using Java SE 1.5. (Note: I'm using Windows so the directory separator is "\")
What Used to work:
1. Nearly all my projects were working using Java version 1.6. These projects were developed as examples from Wrox and Apress books about JSP and Struts.
What has changed:
1. I un-installed the version 1.6 of JDK and JRE, as well as tomcat, netbeans, and all the associated libraries/jars.
2. I installed version 1.5 of JDK and JRE, as well as tomcat, netbeans, and all the associated libraries/jars.
3. I updated my JAVA_HOME, CATALINA_HOME, CLASSPATH, and PATH environmental variables. I made sure that the path to servlet-api.jar (in the tomcat common\lib) is included in the classpath.
What is wrong:
1. References to javax.servlet.* are not satisfied--they are flagged in the source code in NetBeans and I get compiler errors with any project containing those references. For example:
... package javax.servlet.jsp does not exist
import javax.servlet.jsp.*;
What I've found:
1. My CATALINA_HOME=C:\Java\Tomcat 5.5
2. My JAVA_HOME=C:\Java\jdk1.5.0_11
3. My CLASSPATH=.;C:\Program Files\QuickTime\QTSystem\QTJava.zip;%JAVA_HOME%\lib;%JAVA_HOME%\jre\lib;%JAVA_HOME%\lib\jsp-api.jar;%CATALINA_HOME%\common\lib\servlet-api.jar;C:\Java\logging-log4j-1.2.14\dist\lib\log4j-1.2.14.jar
4. My PATH=c:\wint\BIN;%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin;%CATALINA_HOME%\bin;C:\MySQL\MySQL Server 5.0\bin;D:\MiKTeX 2.5\miktex\bin;C:\Perl\bin\;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\QuickTime\QTSystem\;C:\Program Files\Microsoft SQL Server\80\Tools\Binn\;C:\SFU\Perl\bin\;C:\SFU\common\;C:\Program Files\Lahey-Fujitsu Fortran\v7.1\Bin;C:\Program Files\Lahey-Fujitsu Fortran\v7.1\Win32\Bin
What I need:
1. I need to have some reference to the servlet classes satisfied in my configuration. Any help is appreciated.
thanks
jondr

Oh. I got some over-the-shoulder debug help.
My error was in the classpath specification:
The path: %JAVA_HOME%\lib\jsp-api.jar
Should be: %CATALINA_HOME%\lib\jsp-api.jar
That contains the javax.servlet.jsp.*

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.

ANT script genrated error: package javax.servlet does not exist

Hi there,
I am running ANT and confronted this message:
    [javac] Compiling 1 source file to C:\eclipseProjects\tomcat_test
    [javac] C:\eclipseProjects\tomcat_test\WEB-INF\src\WebTest.java:4: package javax.servlet does not exist
    [javac] import javax.servlet.ServletException;
    [javac] ^I googled around and found this solution:
servlet-api.jar is the jarfile that contains javax.servlet.ServletException and javax.servlet.http.* which are imported by WebTest.java and must therefore be found in the classpath. If javac doesn't find this jar (or the javax.servlet packages), it will say (or shout, depending on my and javac's mood): [the error message]
well...I set in the classpath the location of the servlet-api.jar
(found at: C:\Tomcat\common\lib)
I set it with the environment variable (windows xp)
Just as it's shown here: http://www.cs.usask.ca/~wew036/latex/env-env.jpg
NOTHING :-(
could anyone assist, thanks

Hi..seems u r new to J2ee.. dont worry its a very small problem:
Here is the solution.. yes u have to edit the environment variables:..
I am using J2EE sdk 1.4 and running on xp
This is the classpath setting:
C:\Sun\AppServer\lib\j2ee.jar;
This is the PATH setting
C:\Sun\AppServer\bin;
Good Luck :)

Questions about Java Servlets and JSP

Hi,
I'm a confident Java Programmer (and really enjoy using this language) but am very new to Java servlets and Java Server Pages.
I have previously worked with Perl on my web projects (simple 'league' style voting pages). I read in my 'Core Java' book that I should no longer use perl or even cgi.
I need to know more about Java servlets and Java Server Pages so I can make the switch to a 'real' programming language.
I have a few questions:
How should I start to learn JS and JSP?
How applicable will the java knowlegdge I have already be?
Are JSP common on the world wide web?
What tools do I need to start? (I currently develop in JBuilder and have Java 1.4.1 Standard Edition)
Is it likey my web host (and others) will support JSP?
Thank-you very much for helping a novice get started,
Regards,
Paul

Hi, Steve ...has to be frustrating! But do not despair.
Let's suppose the servlet it's named MyServlet on package org.servlets
WEB-INF should look:
WEB-INF
classes
org
servlets
MyServlet.class
web.xml
web.xml file should have this two declarations:
<web-app>
<servlet>
    <servlet-name>MyServlet</servlet-name>
    <servlet-class>org.servlets.MyServlet</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>MyServlet</servlet-name>
    <url-pattern>/MyServlet</url-pattern>
</servlet-mapping>

</web-app>Now, once the container starts (Tomcat?), you should be able to see that servlet in:
http://localhost:8080/[my-context/]MyServletAnd what my-context is? The web application context. This string should be empty if your're deploying to the root context, otherwise should the context name. In Tomcat, deploying to root context defaults to using webapps/ROOT.
Sorry for my English, but I felt the need to answer your request. I hope it helps despite my writing.

Java servlets and Tomcat server

Hi friends
i am using Sun One forte Community edition . i am trying to make a hello world servlet .
there are 2 Files one is Index.html , HelloWorld.java (Servlet)
I call this servlet from the index.html file.
evertime i call it it gives me and error of Apache tomcat file not found .The tomcat server is inbuilt with the Sun One studio.
the directory structure is
-----HOME
-------WEB_FOLDER
----------Index.html
----------WEB-INF
-------------CLASSES
-----------------myServlet (package)
---------------------HelloWorld.java
-------------LIB
The problem is I am not getting how to write the path of servlet in index.html to call the helloWorld servlet.

Make this entry in your server.xml file located in tomcat_dir\conf.
<Context path="/abc"
     docBase="webapps/abc"
     crossContext="true"
     debug="0"
     reloadable="true"
     trusted="false">
</Context>
Suppose i want to develop my servlets in another folder Let it be "XYZ".Then your package statement must be, 'package xyz;'. Place all your servlets in webapps/abc/WEB_INF/classes/xyz dir.
Place all your Jsp(s) and Htmls in webapps/abc/pqrs dir.
Now they all come under one context 'abc'.

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.
