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?

I do not see why you would use two sorts.
And what is the issue exactly by the way? Errors?
So, the records before the Merge Join need to come sorted, to achieve this simply tick:

WLS 8.1 sp1 with Struts 1.1 JSP with bean tag won't compile

          Hello,
          We are currently porting our application which uses struts 1.1 to WLS 8.1 sp1
          from another app server. Everything seems to deploy correctly and pages which
          use struts tags appear to compile and run fine. However, the pages with struts
          <bean:define> tags are not compiling.
          Example JSP Code:
          <bean:define id="userForm" name="userForm" scope="session" toScope="page" type="UserFormBean"/>
          <% if (userForm.hasUserData()) {hasUser=true;} %>
          WLS Console Output:
          ..jsp_servlet\_jsp\_sailor\__home.java:493: cannot resolve symbol
          symbol : variable userForm
          location: class jsp_servlet._jsp._sailor.__home
          if (userForm.hasUserData()) { //[ /jsp/sailor/home.jsp; Line: 38]
          When I look at the JSP's parsed java code (__home.java:493) I find that nowhere
          in the class is the variable userForm declared.
          Is this a bug in WLS? Does anyone know of a workaround?
          Thanks,
          Scott

HELP! Beginning JSP with JavaBean Class

First of all, I'm using jdk1.4 beta and Jakarta's tomcat version 4.0.1 release build.
Hello. I desparately need help. I have a JavaBean class ("CarBean.class") saved in %catalina_home%\webapps\root\myapp\web-inf\classes\com\wrox\cars\CarBean.class
I also have a jsp page saved as carpage.jsp in %catalina_home%\webapps\root\myapp\
So when I point my browser to http://localhost:8080/myapp/carpage.jsp, I get an internal server error. It appears it can't find the JavaBean class for some reason. I'm pretty sure I have my envionment variables set up right. I can get it to work, if I save the JavaBean class in c:\jdk1.4\jre\class\com\wrox\cars
Here's my JavaBean class source file:
package com.wrox.cars;
import java.io.Serializable;
public class CarBean implements Serializable {
public CarBean() {
private String make = "Ford";
public String getMake() {
return make;
public void setMake(String make) {
this.make = make;
and here's my jsp page:
<html>
<head>
<title>Using a JavaBean</title>
</head>
<body>
<h2>Using a JavaBean</h2>
<% com.wrox.cars.CarBean myCar = new com.wrox.cars.CarBean(); %>
I own a <%= myCar.getMake() %>
<% myCar.setMake("Ferrari"); %>
Now I own a <%= myCar.getMake() %>
</body>
</html>
I'm not new to java, just JSP. I just don't know why I can't get the jsp to locate the JavaBean class. I remember I used to have an older version of Tomcat and I recall not having any problems. It seems the Tomcat 4.XX is somewhat significantly different than previous versions. Perhaps I configured my Tomcat wrong? Help would be greatly appreciated. Thanks.

hi
i am not using Tomcat server but as i worked in JWS you have to import the bean class from jsp files.
so the first code in jsp file will be like this
<%@ page import = "CarBean">
becoz JWS cant automatically find the bean class we have to explicitly import bean.but i dont know if tomcat finds
bean or one have to import.
hope this will help u.

Hi Veronika,
The <jsp:usebean> is used for only javabeans not EJB (Enterprise javabean). You said that you have deployed SpellCheck.jar to the JRun server. So that must be an EJB. Where are you accessing this EJB from in your JSP? ARe you doing it inside the projsp.SpellCheck javabean? If yes, can you post some code from the javabean.
Cheers

JSP with Java Class

How to run *.class in JSP. For example, the demo class, Clock.class is run in html format, Can I run the Clock.class in JSP format?

Please notice,
The applet has a graphical context which can draw lines, circules and painting all the object including the background. Now the applet can be load from a jsp page also as if it resides on a html page. Now when you want to use the class Clock.class as a bean inside the jsp page, it has to keep the following definition ( you can't get the graphical context from the applet as a class method in a bean.
The JavaBeans is realy nothing more than a class that maintains some data ( called properties) and follows certain coding convention ( getXX() setXX()) and it has to implements the Serilizable interface and provide no argument for the constructor.
As a result when you want to use the jsp tag for Bean like <jsp:useBean id="MyClock" class="Clock.class" /> keep in mind that the Clock.class is directly located in /WEB-INFO/classes/ in your web application directory.
Now your purpose will be directly oriented to get or set some value for the clock like to get the current time or to set different time zone or to calculate the time in Kurdistan if you are in US etc..
So the Clock class has become a source of hidden business logic operation exposed by methods only.
The graphical animation etc.. is not related to Bean at all event though the applet implements the Seriazable interface

Import a compiled .class or include a .jsp with a class code inside?

which is better and faster, to import a class file or a jsp file that has a class code inside?

I apologize but this is a clarification of this problem. We are having a problem dynamically reloading java classes that are referenced by jsp's and servlets. The problem DOES NOT exist when trying to reload jsps or servlets themselves. We would like to reload these classes without having to restart the processes. Any thoughts would be helpful. Thanks.

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...
org.apache.jasper.JasperException: Unable to compile class for JSP
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.

Need help with JSP - Session Bean scenario

I have massive problems with a simple JSP <--> Statefull Session Bean scenario with Server Platform Edition 8.2 (build b06-fcs)
What I do is generating a Collection in session bean returning it to JSP
and giving the List back to Session Bean.

How to upload a file into server using j2ee jsp and servlet with bean?

How to upload a file into server using j2ee jsp and servlet with bean? Please give me the reference or url about how to do that. If related to struts is more suitable.
Anyone help me please!

u don't need j2ee and struts to do file uploading. An example is as such
in JSP. u use the <input> file tag like
<input type="file"....>You need a bean to capture the file contents like
class FileUploadObj {
    private FormFile srcFile;
    private byte[] fileContent;
    // all the getter and setter methods
}Then in the servlet, you process the file for uploading
    * The following loads the uploaded binary data into a byte Array.
    FileUploadObj form = new FileUploadObj();
    byte[] byteArr = null;
    if (form.signFile != null) {
        int filesize = form.srcFile.getFileSize();
        byteArr = new byte[filesize];
        ByteArrayInputStream bytein = new ByteArrayInputStream (form.srcFile.getFileData());
        bytein.read(byteArr);
        bytein.close();
        form.setFileContent(byteArr);
    // Write file content using Writer class into the destination file in the server.
    ...

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

Problem with JSP using bean packaged in jar file

Hi,
          I am trying to use a java bean in a jsp file. The java bean is packaged
          into a jar file. I am getting class not found compilation error. If the
          bean remains to be a seperated class file, everything work well.
          Does anyone know how I can use bean in a jar file within jsp , i.e. to
          allow the bean to be found during compilation ?
          Thanks,
          Terence.

Jacek,
          Thanks for replying.
          My JSP's are just files in my document root . However, I found a solution to
          my
          problem. That is to have the jar file defined in my weblogic.class.path. I may
          have missed some files in my original jar file which causes my problem.
          Mayby I should package everything into a web application for deployment. That
          will be my next step.
          Thanks anyway.
          Terence.

Importing Bean Class to JSP

Hi here's my bean
import java.util.*;
public class leaveChange extends Object implements java.io.Serializable
     String Name;
     String Grade;
     String Pattern;
     int numDays;
     Date startDate;
     Date endDate;
Now to use this bean in my JSP page what do I do ?
I tried
<%@ page import="leaveChange"%>
but got following error
[javac] C:\Program Files\Apache Group\Tomcat 4.1\work\Standalone\localhost\Devannualleave\newDev\advancedOptions_jsp.java:8: '.' expected
[javac] import leaveChange;
[javac] ^
[javac] 1 error
Thanks in advance

Update
changed Bean class to
package test;
import java.util.*;
public class leaveChange extends Object implements java.io.Serializable
     String Name;
     String Grade;
     String Pattern;
     int numDays;
     Date startDate;
     Date endDate;
JSP File
<%@ page import="test.leaveChange" %>
and have in my WEB-INF/classes/test
my Bean Class
but get the following error
[javac] C:\Program Files\Apache Group\Tomcat 4.1\work\Standalone\localhost\Devannualleave\newDev\advancedOptions_jsp.java:8: package test does not exist
[javac] import test.leaveChange;
[javac] ^
[javac] 1 error
Any help ?

Cant find bean class from jsp page using Tomcat 4

Hi
I have searched numerpus forums and seen many posts from people who seem to have the same problem however none of the solutions seem to work for me.
I have a jsp page which is trying to call a bean method however I get an error
saying that the class for the bean cannot be found. I have :
1. put the class in a package called kolaBean under
C:\Program Files\Apache Tomcat 4.0\webapps\ROOT\begjsp-ch01\WEB-INF\classes\kolaPackage
2. included the package statement in the java file for the bean
3. included an empty constructor in the java file for the bean
4. I have declared the above constructor as public (is this necessary?)
5. used the full package name:
kolaPackage.kolaBean bakedBean = new kolaPackage.kolaBean();
6. imported import java.beans.*; (is this necessary ?)
7. still got the same error...
Any pointers really really appreciated
Thanks
Kola

in reply to David Rons email:
Is this a fresh install of tomcat? If so, it could be a configuration
problem.Yes it is
Is the class public in the package (I forget that all the time)?Yes it is. I have also declared the constructor to be public is this
necessary?
What's the error message?here is the error message:
An error occurred between lines: 11 and 14 in the jsp file:
/begjsp-ch01/kolaBean.jsp
Generated servlet error:
C:\Program Files\Apache Tomcat
4.0\work\localhost\_\begjsp-ch01\kolaBean$jsp.java:59: Class
kolaPackage.kolaBean not found.
kolaPackage.kolaBean bakedBean = new
kolaPackage.kolaBean();
^
2 errors
Thanks in advance
Kola
