There are two ways of getting info from the bean.
1) the jsp:getProperty tag, which seems correct in your code
2) the <%= ... tag. In that case you must write a valid java expression. In your case: list.getValue1()

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.

Problems using GET method in JSP

Hi,
I had some problems using GET method in JSP.
I'm using Apache web server 1.3 and Tomcat 3.3.1 in windows 2000.
And I'm using language English and Korean.
When I send messages using POST method, all is good
But when I send message using GET method, English is good, but Korean is not good.
I tried to encode using
URLEncode.encode(str, "UTF-8")
and decoding it using
URLDecode.decode(request.getParameter(tag), "UTF-8")
but it didn't work.
How can I receive request including Korean using GET method in JSP?
If anyone have solutions, please let me know.
thanks.

thanks.This problem appears, when one use UTF-16 encoding in JSP - am I right?
If so there are two solutions:
1) Temporary: Use "UTF-8" - or any other 8 bit encoding scheme and
encode Korean symbols with "&1234;" kind of escapes - though it
may not work
2) Absolute: get my piece of code, which I have managed to write
just a month ago resolving absolutely similar problem with UTF-16
in code using Chinese/Russian/English encodings
But I wouldn't say that it's costs 10 DDs :) - it's much more
expensive... So try 1st variant if it wouldn't help - let me know.
I'll figure :)

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 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.

          You realy can do it like Xiang says, but the better way is to use packages. That's
          the way BEA is designed for. If you use packages you can but your bean classes
          in every subfolder beneath Classes. Here for example we have the subfolders test
          and beans:
          You have to declare the package on top of your Bean Source Code:
          package test.beans;
          In your JSP you don't need the import code of Xiang. You only have to refer the
          path of your bean class:
          <jsp:useBean id="testBean" scope="session" class="test.beans.TestBean" />
          There are some other AppServers that only can deploy Java Beans in packages. So
          if you use packages you are always on the right side.

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 session bean in JSP

Dear All
I write a BorrowList session bean and tested OK in console mode. I can't use it in the JSP, Dose any body tell me How can I create this bean in the JSP and when should I place the bean classes(Home, Bean and Remote).
I'm now using the BEA Weblogic 7.0
I'm appreicate if anybody can help me.
Best Regards
YU

U may be used the code similar to following :
Context context = new InitialContext.();
Object obj = (Object)context.lookup("Your JNDI name");
YourHome home = (YourHome)obj.portableRemoteObject.narrow(obj,
YourHome.class);
YourRemote remote = home.create();
System.out.println("your Business methods : "+remote.businessMethod1());
Put this code or whatever code used in ur console client in JSP and invoke the businessMethods using remote object.
I worked with BEAWeblogic 5.1, I think similar case may be there with BEA Weblogic7 also.
First, make a jar file with ome.Remote and Bean by using the deploymenttool, then compile with ejb compiler, the new Jar is the complete deployable file. Take this file and register in weblogic.properties file that is specify the path of the Jar file in the weblogic.properties file. and put the JSP in public-html directory and start the server. if the bean is deployed successfully, open JSP file in a browser then it will work.... if the bean is not deployed you won't get any result.
I can say, just placing the initialContext part of code on the JSP and running the JSP. I think, this may helps u...

Using web beans in JSP

I would like to know how create a tree using Web Beans that Jdeveloper provides. Using the web object editor I could add two Beans which mapped to JSTree and JSTreeData(in oracle.jdeveloper.jsp.wb package), though I don't know the difference between them. I tried to include Both these beans in the JSP(which appear as tags) but I am unable to render the tree. Let's say I have a parent node (text: row1, url: url1, 3 childs) and 3 child nodes (text: row2..row4, url: url2..url4, each with no childs). How do I write it in the JSP to render it properly

Using BI Bean in JSP

Hi,
Can anyone please provider some pointers on using BIBeans in a JSP page. There are few options in my knowledge.
1)Using BI-Beans API for writing our own JSP tags.
2)In Jdev(10g) there seems to be some support for Graphs through ADF.
3)JSP and UIX tags provided BI-Graph beans.
thanks

Problem with Session Beans in JSP

Hi,
          I'm testing Weblogic for our company's IT department and just ran into a
          strange error. I wrote a simple JSP script to use a bean that works fine
          except when trying to set the bean scope to session. I looked at the the log
          file and the only exception recorded was a ClassCastException. Could anyone
          please clarify this to me? Is this a current bug in Weblogic?
          Thank you for your attention,
          Paul Visan


          classcastexception are generally due to bad classpaths...
          can you provide more information like what is the code trying to do..stack trace etc..

Problem using struts tags in .jsp

I have a page that fills in the appropriate user information in text fields when viewed. The problem is, i want to have a text field that shows the full name, but i only have getter and setter methods for firstname and lastname in my form bean. Is there a way to combine firstname and lastname to display the fullname using the <html:text> tag ???

You can use an ActionForm for your view that differs from the bean you are using. DynaActionForm would be ideal because it can be tedious to have a full complement of view beans that mirror your value objects.
The idea is to loadup a DynaActionForm with the values for the view before the JSP is called in an Action. The following shows the parts of this and some code for execute() that creates DynaActionForm.
If you have this bean in myapp/Contact.java
package myapp;
public class Contact {
private String firstName,lastName;
public String getFirstName() { return firstName; }
public String getLastName() { return lastName; }
public void setFirstName(String _firstName) { firstName = _firstName; }
public void setLastName(String _lastName) { lastName = _lastName; }
}Put this in the appropriatesecions in struts-config.xml
<form-bean name="ContactActionForm" type="org.apache.struts.action.DynaActionForm">
<form-property name="fullName" type="java.lang.String"/>
</form-bean>
<action path="/showContactForm"
        type="myapp.ShowContactActionForm">
<forward name="success" path="/contactActionForm.jsp">
</action>
<action path="/handleContact"
        name="ContactActionForm"
        type="myapp.HandleContactActionForm">
<forward name="success" path="/contactActionForm.jsp">
</action>And for the execute method in the ShowContactActionForm put...
Contact contact = db.getContact(contactId);
ModuleConfig mc = _mapping.getModuleConfig();
FormBeanConfig fbc = mc.findFormBeanConfig("ContactForm");
DynaActionFormClass dafc =
DynaActionFormClass.createDynaActionFormClass(fbc);
DynaActionForm theForm = (DynaActionForm)dafc.newInstance();
theForm.initialize(_mapping);
theForm.set("fullName", contact.getFirstName() + " " + contact.getLastName());
_request.setAttribute("ContactForm", theForm);
fwd = _mapping.findForward("success");

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'
.....My UserDB class:
public class UserDB
public User getUser(String lastname)
User user = new User();
        try
     Class.forName("org.gjt.mm.mysql.Driver");
    Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/dbconnone?user=smitherson&password=abcdefg");
    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"));
     catch(Exception e)
         System.out.println("Exception..." + e);
   return user;
}Bean class:
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, Sting city)
      this.firstname = firstname;
       this.lastname = lastname;
this.city = city;
public String getFirstname()
          return firstname;
public void setFirstname(String firstname)
     this.firstname = firstname;

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
