Where to put the Bean class in a html- Bean- JSP setup

Hi,
The setup is simple, the front end is a html form, there is a Java Bean with set/get methods and finally a jsp which accesses the bean and prints the result.
The problem is that it cannot locate the Bean class. I have compiled the bean class and stored the .class file in webapps/ROOT/WEB-INF/classes dir. The jsp and html files are located in the webapps/ROOT dir. Iam using tomcat 5.0.28, with ROOT context enabled. Is this because I need to set the CLASSPATH for Tomcat? Any pointers?
Thanks

No you don't need to set CLASSPATH.
You need to put your bean in a package.
As of java1.4, JSPs can not access beans that are in the default/unnamed pacakge.
package mypackage
public class MyClass
and then the class would compile to
WEB-INF/classes/mypackage/MyClass.class

Where to place tld,tag class files to create a small custom tag

hi ,
please any one help me to create a small custom plugin wothout using JSTL

Your TLD will reside in the WEB-INF/ directory, whereas your tag class will be put into WEB-INF/classes/ directory, depending on your package it'll live in a directory somewhere under that. Of course, you could also put the TLD and tag class into a JAR file and place that under WEB-INF/lib/

JSP with Bean Class

Hi,
i am using tomcat server, Where it is store Bean class file, and how to call bean class file in JSP
Pls help me

Thanks, that works when I do this from current dir (C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\servlets-example
\WEB-INF\classes) :
set CLASSPATH=.;%CLASSPATH%
And I have to put the User.java file in the util directory that is located up one directory (C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\servlets-example
\WEB-INF\classes\util).
package util;
import java.io.*;
import java.text.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.sql.*;
import util.User;But it still wont work from the num directory that I had in my original question. I tried setting my classpath to point to the num package:
Set CLASSPATH=%CLASSPATH%;C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\jsp-examples\WEB-INF\classes\num
and it gave me same error.
Please advise or should I just live with the servlet calling the class in the util directory and forget about the num directory?

Where to place javabeans in tomcat

I have a problem finding my javabeans in apache tomcat 4. I have a project with jsp pages in a folder called crm. I have made some java beans which is in com.xxx.crm.beans package (folders). these folders (package) is placed in the crm folder and in my jsp page I use this code:
<jsp:useBean id="ValidationBean" scope="session" class="com.xxx.crm.beans.ValidationBean" />
<jsp:setProperty name="ValidationBean" property="*" />
what am I missing out? I have also tried to restart tomcat. Do I have to place javabeans in the appservers classpath?
Structure:
crm/
login.jsp
crm/com/xxx/crm/beans/
validationbean.class
thanks in advance.

Where I should put the bean class?

Hello,
I am learning JSP. I want to know where I should put the bean class? Which directory should I put the bean class?
note that I am using Tomcat 4.1

I can't tell if you've got everything you need or not, but what you've shown looks right so far. Let me run down the necessities:
In your JSP file:
<%@ page import="aos.*" %>
<%-- imports all of the classes in the "aos" package --%>
In your Java file:
package aos; // tells Java this is a package (you probably have this)
Then, of course, you put the class file into the directories that you mentioned, ie, $CATALINA_HOME/ROOT/WEB-INF/classes/aos (forgive me if I use Unix-styled slashes; old habit, and shouldn't make any difference.)
You may need to restart Tomcat. You have to restart it when you add certain directories, although I'm not sure exactly which ones. But it never hurts to just restart it anyway.

TOMCAT CAN�T FIND BEAN CLASSE

Hello, i am from Argentina. i need URGENT help with tomcat, because i am developing my final thesis.
I have all my sources in
C:\jakarta-tomcat-5.0.16\webapps\tesis
C:\jakarta-tomcat-5.0.16\webapps\tesis\ (archivos jsp)
C:\jakarta-tomcat-5.0.16\webapps\tesis\lib
C:\jakarta-tomcat-5.0.16\webapps\tesis\web-inf\classes\edu\tesis\beans
C:\jakarta-tomcat-5.0.16\webapps\tesis\web-inf\classes\edu\tesis\queries
C:\jakarta-tomcat-5.0.16\webapps\tesis\web-inf\classes\fede\servlets
my problem is that when i execute the login.jsp through the browser in this way
http://localhost:8080/tesis/login.jsp
tomcat can�t find the edu.tesis.beans package
In compiled jsp class i can see this
package org.apache.jsp;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.jsp.*;
import edu.tesis.beans.*;
so, the problem is that tomcat set package org.apache.jsp; to my jsp, so it can�t find edu.tesis.beans package.
This is my context path that is in $CATALINA_HOME/conf/server.xml file
<Context path="/tesis" docBase="C:\tomcat\webapps\tesis"
debug="9"
reloadable="true"
crossContext="true"/>
This is an extraction of my jsp file
<html>
<head>
<%@page import="edu.tesis.beans.*"%>
</head>
<body>
<jsp:useBean id="universidad" class="edu.tesis.beans.Universidad" scope="request" />
<form action="servlets/fede.servlets.ServletMaxwell" method="post"><BR><BR><BR><BR>
PLEASE, I NEED AN URGENT HELP!!!!
THANKS,
FEDERICO

Tampoco te preocupes porque Tomcat cambie el paquete de las p�ginas jsp. Eso es un comportamiento normal. Adem�s nota que el paquete de tu tesis es importado en la clase generada a partir del jsp, o sea que deberia encontrarla si est� en el lugar correcto.
Otra cosa que veo extra�a en tu estructura de directorios es que existe un directorio "lib" por fuera de WEB-INF. Si este contiene beans en forma de paquetes jar, deberia estar dentro de WEB-INF

Can not call bean class from JSp/Tomcat 5.5

hello everyone...
i m using one bean class Parser which is called by discussion.jsp page. i put class file in webapps/grid/WEB-INF/classes and JSP page is in webapps/grid/. The whole combination is working fine for tomcat 3.3.2 but not working properly in tomcat 5.5.
Error is as follow...

An error occurred at line: 38 in the jsp file: /discussion.jsp
Generated servlet error:
Parser cannot be resolved or is not a typeplease help me....
Thank in Advance

You still need to import the class from the default package. As a word of advice you should put the class in a package. The later versions of Tomcat do not play well with bean classes that are not in packages.

How to place a servlet file in Tomcat 5.0?

Hi,
i'm using Apache Tomcat 5.0 as myweb server.i don't know how to set the class path and where to place my servlet and html files,and how to run my servlet file.if anybody knows plz give me a detailed description abt this topic.

Look at the directory structure of your Tomcat installation directory. You will see a webapps directory under that. The Tomcat installation comes with samples ready to run. Look at those and create a similar directory structure under webapps for your application. I don't think you need to worry about classpath. Tomcat should be taking care of all that if you create the proper directory structure.
You run your servlet by specifying a url like:
localhost:8080/servlets-examples/from a browser. This assumes that your installation is using port 8080 which I think is the norm for Tomcat. Here "servlets-examples" is the name of the directory you created. Actually Tomcat 5.0 comes with a "servlets-examples" application. This would be a good directory to look at. You could also run their examples to get a feel for it.
If you are new to servlets, you'll probably have to get a book that explains how things need to be set up. You'll need to create a web.xml for your application. If you look at the servlets-examples directory under webapps, you'll see that it has a WEB-INF directory under it and that directory contains a file called web.xml as well as a sub-directory called classes. This structure is standard accross all application servers because it corresponds to the war (wars are specialized types of jars for web apps) file standard.

For WebLogic 5.1, where should I put my class files for my JavaBeans?

With JBuilder4, I have built an application with JSP and a few Java Beans (Those JavaBeans are instantiated in those JSP files). There are no EJBs. The package name is called 'onlinetrade'. I have tested the application on JBuilder's web server, it works pretty well.
Now I am moving this application to WegLogic 5.1. I have encountered a problem with WebLogic 5.1
and do not know where I should place my JavaBean class files --
Originally, the JSP files for my application are in package path-- ..onlinetrade\jsp
and the class files for my beans are in the package path -- ..onlinetrade\jsp\bean\*.class
Now, with WebLogic 5.1,
1) I have put my JSP files in
C:\weblogic\myserver\public_html\onlinetrade\jsp
2) I have created subdirectory and put my bean class files in
C:\weblogic\myserver\classfiles\onlinetrade\jsp\bean
When I started weblogic and the first page - login.jsp page can be up and accessed. But when I login and forward to another JSP page called 'controller.jsp', where a bean is instantiated, I got the following error
Compilation of 'C:\weblogic\myserver\classfiles\jsp_servlet\_onlinetrade\_jsp\__controller.java' failed:
C:\weblogic\myserver\classfiles\jsp_servlet\_onlinetrade\_jsp\__controller.java:210: cannot access jsp_servlet._onlinetrade._jsp.registerBean
probably occurred due to an error in /onlinetrade/jsp/controller.jsp line 53:
registerBean registerBeanInstance = new registerBean();
I know the javac is working, and a java file is created upon the JSP page, but the problem is -- the bean class files cannot be found!!!
Where should I create the package path and put my bean class file so that my JSP pages can pick them up?
Any help is greatly appreciated!
Thanks.

Where should JavaBeans be placed when using Tomcat?

I want to use a javaBean from inside a JSP, but it seems like Tomcat can't find the bean (...can't find the class).
Is there a particular catalogue where the bean-classes should be placed?
My test-JSP looks like this:
<html>
<head>
<title>Untitled</title>
</head>
<body>
<jsp: useBean id="enBean" class = "ASimpleBean"/>
</body>
</html>

Your problem most probably is that your class isn't a member of a package. A recent change to the way java/tomcat works is that classes in the default package (ie no package) aren't visible any more.
Put your class in a package(eg SimplePackage), so your className would become simplePackage.ASimpleBean
The class files should be placed under your web-inf/classes directory on your web application.
Hope this helps,

I have a complaint about my mac book pro being slippery. Why do these expensive computers that we as consumers purchase if you set them on a couch slip off no matter where you place them on the couch?

Hi, my Mac Book Pro 15 inch lap top if i set it on the couch no matter where I place it slips off and luckily so far I have caught it before it falls onto the floor and gets ruined, of which I am super afraid of, due to what I initially paid for it as the consumer. Also, the couch is not made of slippery material at all. Also, when using it on my lap while watching tv, and multi tasking while doing my college homework, it even slides off of my lap at times. Why is it called a lap top then when it's not working as one? Are we to wear rubber pants that grip your products? Also, Why do you place on your Apple website that in one area a satin cover is available in the teal color, and then in another area it's discontinued? I believe it would be simpler if Apple would just remove the product all together from the purchasing website once any product becomes discontinued. Also, I was sitting here at home waiting for a reply about the satin cover in teal no longer being available period or that it has shipped, but yet I ended up calling Apple altogether myself and finding this all out that the only available color is the black. It would've been nice to have recieved an e-mail or a phone call on why it wasn't going to be shipped, or shipping instead of having to do customer services job and doing the leg work myself. Also, why is it that no one also even tells a consumer about the classes that were offered to a new consumer for 14 days after purchase of paying the $99.00s to learn about their macs of any kind? If I had known about such a program, I surely would've signed right up for it. Now I am being told that I can only take one clas at a time or something?!? I seriously wish I was told about this as a consumer of the Mac Book Pro 15 inch, because I would've purchased that offer right away, and now I am stuck and can no longer do it. Also I have had my computer since October of last year. So, I am in college as becoming a graphic designer within a degree of an Associates of Science and am now still struggling to learn the computer, and the programs I pruchased as well at the time of purchase, along with an Epson printer, the magic mouse, and the one year warranty. As for this all, I do believe that Apple needs to make a better bottom to the Mac Book Pro's within a much better quality for the price we pay as consumers, and all other lap tops and/or Notebooks in making them slide proof. The tiny rubber spots on the bottom of the lap tops or any Apple computer similar to mine just needs a better quality improvement to us consumers I spent good money on this purchase, I think now I deserve a rubberised protective cover for free for the slipperyness, and also since I was never told about the program for the classes of which a consumer was to pay $99.00s for, I think as a good paying quality consumer for Apple's products, I now deserve these classes for free as well.
Sincerely,
Kim

Hi shldr2thewheel,
it has been a while since we have last spoke, I would like to let you know, I am still working on getting used to the switch from windows to a Mac/Apple system. I do have a new question for you, I did purchase In Design CS5.5 through journeyed.com through Cuyahoga Community College of which I attend as a student, is there a way to purchase an online book through iTunes to learn that as well? Also, you know me, the struggling student, I would also, when and if the book can be purchased through the iTunes, would need to know if you do know of a much easier book for struggling students like myself and at a reasonable price as well for the In Design CS5.5 program. Our campus bookstore had closed early, and, so did the colleges library and our local library here where I do live, so, I cannot go to either place to purchase a book or to take out a book, plus cash funds are low at this moment as well but, I do have money left on the iTunes account to use, if it can be used. So, can it be used, the iTunes money, towards finding a low priced online book? I am in great need of assistance as I have a project due for my one course for this Tuesday, September 4, 2012.
Sincerely in need of help once again,
Kim
