Problem in Using Java Bean in JSP

Hi,
I have a bean called BankAccount.....I tried to use it in a jsp file called Usebean.jsp like this <jsp:useBean id="BA" class="BankAccount" scope="application" /> I tried in both tomcat and j2ee1.3 server... but when i run the jsp file i get an error saying..... Class.org.apache.jsp.BankAccount not found...... But i have put the class file properly inse classes folder.....
Can anyone help me soon..... i am new to JSP........
Thanks,
Akshatha

Well u need to have your class in a package
like mypackage.BankAccount
and put your class in classes/mypackage
<jsp:useBean id="BA" class="mypackage.BankAccount" scope="application" />

Using java bean with jsp

hello friends,
i'm new to jsp. i want to create an html form that accepts username and a value from four radio buttons and display back the entered name and checked radio button's value using java bean.
i use the <jsp:setProperty id="" property="*"> method. i don't know how to access the radio buttons value from the html.
also when i use an additional field other than username the jsp page is showing error.
Please give me the correct method to use java bean with jsp in this circumstance.
thank you.

thank you, but i have a problem left. the case is like this.
i got the jsp and bean worked fine when i have a sinle input text field.
but when i added a second text field i recieved the following error.

Using java beans in jsp using tomcat

hi i have made a form to enter user first name and last anme with html and then i have made a value javabean in which i want to store the information filled bu user. i want to display the information stored in java bean in jsp page i have made the full application and i have made class file of java bean as well as jsp file but when i try to run this web application in tomcat i am getting class not found exception.
could anybody tell me that where i should store the bean class in tomcat and do i need to make any package in which i have to place my java bean file plz tell me complete procedure along with code if possible

whew thats a lot of questions... All of this is pretty basic stuff. I would recommend you take a look at the web services tutorial: http://java.sun.com/j2ee/1.4/docs/tutorial/doc/
lets see.
Starting a package name with com is just a generic standard which is followed.
It is most correct when creating commercial packages to create packages like com.companyName.project
http://java.sun.com/docs/codeconv/html/CodeConventions.doc8.html
You should not need a page import directive unless you are using classes in scriptlets: ie <% %> tags in your JSP. Your jsp:useBean tag will automatically import necessary classes - you don't need to import classes for beans specifically
<jsp:useBean id="myClass" scope="session" class="com.myPackage" />
Your directory structure should be something like this
webApplicationRootDirectory
- page1.html
- page2.html
- page3.jsp
- page4.jsp
- WEB-INF
     - web.xml
     - classes
       - com
         - myPackage
           - myClass.classerrrm. Thats about it I think.

Using Java Bean in JSP to show database record

I have links in my Tomcat container that if someone clicks on a specific link it should go to a Record page (Show.jsp) with all the values associated with a record from a database.
For example if someone clicks on a specific link like this:
LinkExample
it would take you to a jsp with database info for someone named Jones and show you his info:
Lastname = Jones
Firstname = Mike
City = San Diego
I would like to do this using a Java helper class and bean so I dont have any database connection or Java code in my JSP.
I created Java class file that has Database connection that works with a Java bean. I just dont know how to get the Show.jsp to work with the Java Bean and Java helper class file.
Here is what I have for Show.jsp and this is the part I have been working on the longest but cant get it to work because it doesnt seem to work with the database:<jsp:useBean id="user" class="num.UserDB"/>
//do I call getUser(lastname) here and if so how?
<jsp:setProperty name="user" property="*"/>
Last Name: <jsp:getProperty name="user" property="lastname"/><BR>
First Name: <jsp:getProperty name="user" property="firstname"/><BR>
City: <jsp:getProperty name="user" property="city"/><BR>My Java Helper class that compiles and connects to database:
package num;
import java.io.*;
import java.sql.*;
import java.util.*;
import num.User;
public class UserDB
public User getUser(String lastname)
User user = new User();
        try
     Class.forName...//database connection stuff here
    ResultSet results = stmt.executeQuery("SELECT * from user where lastname = '" + lastname + "'");
     if(results.next() == true)
     results.next();
     user.setLastname(results.getString("lastname"));
     user.setFirstname(results.getString("firstname"));
        user.setFirstname(results.getString("city"));
     catch(Exception e)
               System.out.println("Exception...");
   return user;
}My Java Bean that compiles here:
package num;
public class User
private String firstname;
private String lastname;
private String city;
public User()
     //no arg constructor
public User(String firstname, String lastname, String city)
       this.lastname = lastname;
          this.firstname = firstname;
          this.city = city;
public String getLastname()
          return lastname;
public void setLastname(String lastname)
     this.lastname = lastname;
//more bean methods for all fields here

Sorry if I wasnt specific enough. I have a link that passes a value (field that is passed is called lastname) to a JSP where I want to show record info for that value that is passed.
My question is how do I show the database record info on Show.jsp for the lastname field value of Jones where I want to use a Java Bean and Database helper class in Show.jsp
Here is the message I get when I hit the link (LinkExample) and it goes to Show.jsp:
org.apache.jasper.JasperException: Cannot find any information on property 'lastname' in a bean of type 'num.UserDB'

    Statement stmt = conn.createStatement();
    ResultSet results = stmt.executeQuery("SELECT * from user where lastname = '" + lastname + "'");
     if(results.next() == true)
     results.next();
     user.setLastname(results.getString("lastname"));
     user.setFirstname(results.getString("firstname"));
                     user.city(results.getString("city"));

   return user;

How can i use JAVA BEAN and JSP?

well, i have developed all my web apps by using pure JSP only, i know this sucks, but i dont know how to start on using beans... what directory should i put them into... etc... what are the good programminmg practices/standards/techniques when incorporating beans in jsp???

Standards are pretty loose, but generally, Beans hold a lot of the backend logic for your JSP. This can include data validation before entering into the database, database inserts, queries, data manipulation. The JSP should really only contain code that will retrieve the data from the bean and appropriately output it.
As far as using them, you can use the <jsp:useBean> tag in your JSP. As long as the bean is stored somewhere that your classpath points to, you're all set. From then on, you can use it like any other object in your JSP.

Using java beans in jsp

Hi, I need to do this, can any one help me.
In the signup form, i have some text frields like this
HTML
<form action=http://localhost:8080/servlet/Signup.jsp">
<input type=text name=name>
<input type=text name=phone>
<input type=submit value="Submit">
</form>
JAVASP
req.getParameter("name");
req.getParameter("phone");
i am doing some validation here like if the user name exists in the database i am diverting him to the html page like this
rs = st.executeUpdate("select * from regi where user="+name+"");
if(rs.next())
here i need to call the html page in the from of a bean and with the old values intact to it
else
insert into regi values('"+name+"','"+phone+"')
this is how i am doin my html in the form of a bean
<%!
public void beans()
%>
<form action=http://localhost:8080/servlet/Signup.jsp">
<input type=text name=name value=<%=name%>>
<input type=text name=phone value=<%=phone%>>
<input type=submit value="Submit">
</form>
<%!
%>
but this is giving me error, can any one help me please?
Thanks
Uma

Hai Uma,
I read ur code like this.
<%!
public void beans()
%>
<form action=http://localhost:8080/servlet/Signup.jsp">
I think here is the mistake. <%! %> - for declaring variables. But for writting codes we have to use <% %> tags only. Can u try the same program by removing "{" in this tags or remove "!" from tag...
I hope this may helpful to u to solve ur problem
With Regards
Siva

What's the difference between using java directly in JSP and java bean

What is the difference if I use java code directly in JSP or use java bean in JSP?
Which class to use for receiving the passed parameter from html or java script? Any difference for java code and java bean in the way receiving the passed data?
How can I pass string from jsp to html or java script?

1 Cleaner pages
2 you have to write the class and use set and get methods
3 What do you mean when saying passing string from jsp to html??, do you mean the value you can use <%=variablename%>

How can I pass string from jsp to html or java script?

it's generally accepted as better design to separate presentation from logic. meaning, the java code in the jsp should be used to support displaying data, as oppsoed to implementing the application - like database access, etc.
when the logic is separated from the presentation, it allows you to reuse logic components within several jsp pages.
if you decide to change the presentation layer in the future (to support wap, for example) you don't need to rewrite your entire application, since the "guts" of the application is outside of the jsps.
it is also a good idea to separate your business logic from your data layer. adding a "buffer zone" between these layers helps in the same manner as in separating presentation from logic. if you're using flat files for storage now, upgrading to a database wouldn't require rewriting all your business logic, just the methods which write out the data to a file, for example.
once you feel comfortable with separating the various layers, check out the struts framework at http://jakarta.apache.org/
to answer your second question, to get parameters passed in from HTML forms, use ServletRequet's getParameter() method.
in tomcat:
<% String lastName = request.getParameter( "lastname" ); %>
to answer your third question: when displaying the HTML from withing a jsp, print out the string to a javascript variable or a hidden form element:
<% String firstName = "mike"; %>
<input type="hidden" name="firstname" value="<%= firstName %>">
<script language="javascript1.2">
var firstName = "<%= firstName %>";
</script>
this jsp results in the following html:
<input type="hidden" name="firstname" value="mike">
<script language="javascript1.2">
var firstName = "mike";
</script>

Stepping into Java Beans from JSP

I am trying to figure out how to step into the Java Source code for my beans that are used in my JSP pages. I need to be able to debug them by stepping into them, using break points, etc.
I have Nitro installed and a sample JSP page with the import to my test Java Bean class. What I did was create two projects in my work space. One as a Web project application and one as a Java project. I referenced and opened both projects. Everything compiles fine and the syntax is correct.
The problem is I can not make the link for importing the class.
I get this error: Class com.BrianTest.MyBean not found in import com.BrianTest.MyBean
Anyone got a clue or a good example? I did try and add the class path and I tried to put it in a Jar file and attach the source to the Jar, but same problem.
Thanks :?

Stepping into jsp:useBean is not possible, but you can step-into jsp getter & setter tag.
Since you are using java bean from a dependent project you need to configure your server with DevLoader.
And currently only Tomcat server can be configured with Sysdeo Devloader to handle this situation
Download Sysdeo DevLoader for Tomcat from http://www.sysdeo.com/eclipse/tomcatPlugin.html
NOTE: If the project is self sufficient and not dependent on other projects/locations for classess/libraries then NitroX picks up all the libraries & classes present within default WEB-INF/lib & WEB-INF/classes respectively. And in this case you need not modify server configuration.
Sysdeo DevLoader is to allow your web project to use libraries/classes from dependent projects. All you need to do is extract DevLoader.zip present within tomcatPluginV3.zip inside your Tomcat/server/classes folder.
For more information about DevLoader please refer to http://www.sysdeo.com/eclipse/readmeDevLoader.html
This will solve your problem and you should be able to run/debug your application. And most important make sure you have the correct NitroX build that supports Sysdeo DevLoader, refer http://www.m7.com/whatsnew.htm document against your build id (Help > About NitroX > NitroX Icon)

First reaction: yuck.
This is not something you should be using a bean for.
Beans are meant for storing data, not for generating HTML from.
I don't really like queries on a JSP page either, but thats a different story again.
I would recommend you use JSTL for this.
1 - it provides a c:forEach tag for looping
2 - it provides sql tags for doing queries in a database
IF you are going to do database queries from a JSP page, I absolutely recommend you use the JSTL tags.
(end rant)
Your problem is probably caused by the fact that in your bean you have the following
try{
// code here
catch (Exception e){
// completely ignore exception and carry on as if nothing bad happened.
// what you should be doing is something like:
System.out.println("Error occurred " + e.getMessage());
e.printStackTrace();
return e.getMessage();

Using java beans to store records from recordset

Hi there,
I have been stuck on an issue with Java Beans in JSP for the last few days and cant get my head around it.
I am basically trying to retrieve all the records out of a resultset which pulls records from a table through a JDBC connection and store the records in a html table using the java beans getProperty tag.
Problem is that the first row of the recordset is being applied to every row in the table. I have tried implementing for loops to iterate through the result set but without any luck.
I need help urgently
Thank you

Thanks for the feedback M
I have added the JSTL 1.1 library and used the Foreach components and data source components which now totally eliminate the need for beans altogether. :P
<c:forEach var="row" items="${deejays.rows}">
<tr onmouseover="this.bgColor='gold';"
onmouseout="this.bgColor='#FFFFFF';">
<c:forEach var="column" items="${row}">
<td>
<c:out value="${column.value}"/>
</td>
</c:forEach>
<td width="24%" align="center">
<input type="image" src="7af5.jpg" name="test" value="test"/>
</td>
<td width="15%">
<input type="radio" name="book1"/>

Thanks a lot

Seems to me that executeUpdate() would throw an SQLException, which in turn would get caught by your empty catch. The SQL keyword VALUES is misspelled. Put a 'se.printStackTrace()' in your catch to confirm this.

Problems with a java bean in Weblogic 5.1

Hello,
          I am having a problem deploying a java bean in Weblogic 5.1:
          I have been given a .class and a .jar file for a java bean (not an EJB). I
          placed the .class file into e:\temp\WEB-INF\classes and added the following
          line to my weblogic.properties file:
          weblogic.httpd.webApp.testApp=e:/temp/
          I have also updated the web.xml file in the WEB-INF directory as follows:
          <?xml version="1.0" encoding="UTF-8"?>
          <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web
          Application 1.2//EN"
          "http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
          <web-app>
          <servlet>
          <servlet-name>EdIface</servlet-name>
          <jsp-file>test.jsp</jsp-file>
          </servlet>
          <servlet-mapping>
          <servlet-name>EdIface</servlet-name>
          <url-pattern>EdIface</url-pattern>
          </servlet-mapping>
          </web-app>
          When I try to access my http:\\server:port\testApp\test I get an "Error
          500 - internal server error".
          Has anyone had experice with deploying a java bean with jsut the .class and
          .jar file? Where should I put the .jar file?
          I appreciate any advice!

Why use Java Beans?

Why should we use java beans?
Everybody says it is used to set the properties. What does this mean?
Can anyone give me a realtime scenario of the problems it can solve?
How does Spring framework utilize beans to solve problems? i.e wiring beans, declaring them in context file.
