Help with jsp
How can one access the servletContext object from within a bean that was instantiated using <jsp:useBean ... />?
try this:
<jsp:useBean id="mybean" ... />
<jsp:setProperty name="mybean" property="servletContext" value="<%= application %>" />
of course, the bean needs a field to hold it.

Any help with this will be really appreciated. I'm new to programming.
If I search for an ssn in a database, I want to view all records relating to that ssn. However, I am getting all the records in the table.
eg.
at the prompt for ssn, let's say I enter 111111111
I would like to see
111111111 abc xyz etc
111111111 pdg ppp etc
however, I am getting
000000000 utt tui etc
111111111 tug etg etc
How do I make limit the search to the ssn I want?
The related code is below.
Thanks.

Help with JSP and logic:iterate
I have some queries hope someone can help me.
I have a jsp page call request.jsp:
====================================
<%@ page import="java.util.*" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<html>
<body>
<%@ page import="RequestData" %>
<jsp:useBean id="RD" class="RequestData" />
<%Iterator data = (Iterator)request.getAttribute("Data");%>
<logic:iterate id="element" name="RD" collection="<%=data%>">
<jsp:getProperty name="RD" property="requestID" />
<%=element%><br>
</logic:iterate>
</body>
</html>
And I have the RequestData.java file:
======================================
private int requestID = 1234;
public int getRequestID() { return requestID; }
The jsp page display:
======================
0 RequestData@590510
0 RequestData@5b6d00
0 RequestData@514f7f
0 RequestData@3a5a9c
0 RequestData@12d7ae
0 RequestData@e1666
Seems like the requestID is not returned. Does anybody know this?
I have done the exact one using JSP and servlets, trying to learn using JSP and custom tags. The one with JSP and servlet looks like:
============================================
<%@ page import="RequestData" %>
<%Iterator data = (Iterator)request.getAttribute("Data");
while (data.hasNext()) {
RequestData RD = (RequestData)data.next();
out.println(RD.getRequestID() );
}%>Oh think I got it...
but one thing I'm not sure is...
If I use "<jsp:useBean id="RD" class="RequestData" />", do I still need "<%@ page import="RequestData" %>"?
I tried without and it gives me error... -

Please help me.....Actually you're probably off on a false trail with jsp:useBean. The more up to date methods use tag libraries (typically JSTL) and access bean attributes using EL, bean expression language. E.g. you put your initial form data into a request attribute called "data" and you put:
<input type="text" name="property1" value="${data.property1}" ....useBean is no use for binding returned fields from a form. Always remember that your JSP generates HTML and once that HTML is sent to the browser that's it, the JSP has done it's job and finished. Only with JSF, at present, does what you write in your JSP affect the processing of received form data. When you get the form data back you need to "bind" the values from the request back to the bean. A framework like Spring will do this stuff for you, but in a raw Servlet/JSP environment it's up to you. -
Help with JSP/Weblogic/Tomcat Discrepencies
Hi,
I have something very strange happening. I recently did some JSP stuff on
WLS60SP1 and all went quite well. I then took those same JSP pages and tried
them out on the latest release of TOMCAT. I was really impressed that
everything seemed to be completely transparent and working just fine until
the following situation:
When I reference, within a JSP page, an object that has previously been
added to the request scope that has just been created, but not messed with
in anyway...meaning all the attributes in this bean have their default
values set...and they are all Strings with the exception of one Integer
using this format:
<%= custVal.getCustomerNumber() %>
- In WLS, what shows in the text field on the form is nothing, because
customer number in the custVal object is null (default for a String)..this
is what I want.
- In Tomcat, what shows it the word "null".
...here is the weird part, by changing from scriptlet references to the
<jsp:getProperty....> format such as....
<jsp:getProperty name="custVal" property="customerNumber"/>
-In WLS, he is still a happy camper and works just fine regardless of how I
reference the bean
-In Tomcat, I also get the correct results that I want.
So, unlike most postings, I found out how to fix it but I would like to know
why...any ideas?
Thanks in advance,

I have 3 pages ...1) index.jsp 2) Forward.jsp 3) welcome.jsp
I have 2 fields in the index.jsp once upon filling & hit submit it has to to go Forward.jsp page...in the Forward.jsp..i have coded only one tag with
<jsp:forward page="welcome.jsp" />
I have one question...once the page comes to Forward page...will it display the contents of the Welcome .jsp in the same page itself...or it will go to Welcome.jsp page..
As i saw it will display the contents of Welcome.jsp page in itself...
Please let me know...
Regards
GnaneshI understand your question only because I have a set up totally identical to yours. The thread Matt suggested does explain the situation (i.e. the server passed control to another page but the client doesn't know that), but doesn't necessarily give a good solution a problem that you may have, and that I do have:
If the user sees the welcome page, and for some reason decides to "reload", the forward page is re-executed, even though it has done its job. This could be a problem for session management if you specifically don't want that job being done twice in a session. Now you could hack around that, but I'd really rather see a neat solution. Is there one? -
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)

any pros please help? i know it's something to do with my jsp session validation. thanks in advance.one more thing, with regrads to the solution evnafets provided. I tried it out on all my pages that requires administrator rights and found that the code only redirects when it's not expecting any parameters. Else, it just display an error message there. Is there a way around this? Or I should let let my end user suffer?

Help with jsp and javaBean in eclipse/Tomcat
Hi,
I am new to JSP and JavaBean. I am going through tutorial for a jsp page that uses a javaBean. I am using eclipse to create jsp page and the java bean.
My eclipse project "Date" has five package as under:-
1. Deployment Descriptor
2. Java Resources: src
3. build
4. WebContent
I have my data.jsp page in WebContent/WEB-INF/ folder. When I just run date.jsp in a browser as: http://localhost:8080/Date/date.jsp, it gets launched into the browser correctly. But when I add a JavaBean "TimeFormatterBean.java" in the Java Resources:src folder and use it in date.jsp page, I get errors as under:-
org.apache.jasper.JasperException: Unable to compile class for JSP:
An error occurred at line: 5 in the jsp file: /date.jsp
TimeFormatterBean cannot be resolved to a type
2: pageEncoding="ISO-8859-1"%>
3: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
4:
5: <jsp:useBean id="formatter" class="TimeFormatterBean"/>
6:
7: <html>
8: <head>
The data.jsp page is as under:-
<jsp:useBean id="formatter" class="TimeFormatterBean"/>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<h1> Date JSP </h1>
<p> The current time is:
<%= new java.util.Date() %>
<jsp:getProperty name="formatter" property="name"/>
</p>
</body>
</html>I can see "TimeFormatterBean.class" in build/classes folder.
If anyone could please help me out with this, it would be very helpful
Thanks a lot!You probably should place TimeFormatterBean inside a package, or maybe you could try importing it , even if it�s in the default package, with something like this <%@ page import="TimeFormatterBean" %> at the top

Need serious help with JSP + JDBC/Database connection
Hey all,
I have to build an assignment using JSP pages. I am still pretty new and only learning through trial and error. I understand a bit now, and I have managed to get a bit done for it.
I am having the most trouble with a Login Screen. The requirements are that the a form in a webpage has Username/Number and Password, the user clicks Login, and thats about it. The values for the username/number and password NEED to come from the database and I cannot manage to do this. The thing I have done is basically hardcode the values into the SQL statement in the .jsp file. This works, but only for that one user.
I need it so it checks the username/number and password entered by the user, checks the database to see if they are in it, and if so, give access. I seriously am stuck and have no idea on what to do.
I dont even know if I have made these JSP pages correct for starters, I can send them out if someone is willing to look/help.
I have setup 3 other forms required for the assignment and they are reading data from the db and displaying within tables, I need to do this with non-hardcoded values aswell. Im pretty sure I need to use for example 'SELECT .... FROM .... WHERE username= +usrnm' (a variable instead of username="john" , this is hardcoded), I just CANNOT figure out how to go about it.
Its hard to explain through here so I hope I gave enough info. A friend of mine gave some psuedocode i should use to make it, it seems ok to follow, its just I do not know enough to do it. He suggested:
get the username and pass from the env vars
open the db
make an sql (eg SELECT user, pass FROM users WHERE user = envuser)
index.jsp points to login.jsp
login.jsp get the vars you put into index.jsp
opened the db
is the query returns nothing - then the user is wrong
OR if the passwords dont match
- redirect back to index.jsp
if it does match
- set up a session
- redirect to mainmenu.jsp
Anyway, thanks for any help you can give.
-AaronHi,
Try this... it may help you...
mainMenu.jsp
<html>
<body>
<form method="POST" action="login.jsp">
Username: <input type="text" name="cust_no">
<p>
Password: <input type="password" name="password">
<p>
<input type="submit" value="LOGIN">
</form>
</body>
</html>
login.jsp
<%@ page import="java.io.*, java.sql.*"%>
<html>
<body>
<%
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection connection = DriverManager.getConnection("jdbc:odbc:rocky");
Statement statement = connection.createStatement();
String query = "SELECT cust_no, password FROM customers WHERE cust_no='";
query += request.getParameter("cust_no") + "' AND password='";
query += request.getParameter("password") + "';";
ResultSet resSum = statement.executeQuery(query);
if (request.getParameter("cust_no").equalsIgnoreCase(resSum.getString("cust_no") && request.getParameter("password").equalsIgnoreCase(resSum.getString("password"))
%>
<h2>You are logged in!</h2>
<%
else
%>
<h2>You better check your username and password!</h2>
<%
}catch (ClassNotFoundException cnfe){
System.err.println(cnfe);
}catch (SQLException ex ){
System.err.println( ex);
}catch (Exception er){
er.printStackTrace();
%>
</body>
</html>
I didn't check the code that I wrote. So you may have to fix some part of it. Also this may not be the best solution, but it will help you to understand the process easily.
The more efficient method is to check whether the result set returned from the database is null or not.... I hope you got the idea... Good luck!

Howdy all,
I have a
<jsp:getProperty name='input' property='code01'/>
tag and would like to be able to put a variable in the property field so that I can increment from code01 to code02 to code 03 by concatenating strings
Is this possible?Thanks for your input on the forum, but I tried with no sucess to put it into action:
<% String colname="code02"; %>
<jsp:getProperty name='Input' property='<%=colname%>' />
Produced this:

Anyone can help?
Thanks a lot.

warrenHi , I have similar problem. wonder anyone can help me. I have a datastructure. ArrayList contains list of Hashtable; each Hashtable has two key-value sets ; for each key-value set , value is a ValueObject.
My jsp works ok. but when I click on the radio butten for one radio group, it sets not only the porperty on that row, but the rows belows ,which suppose to be another radio group , because I am using indexed="true". each row should be a individual group seperated by the name poDisplayVO[i] , as show in the html generated .
<!-- JSP -->
<logic:iterate id="poDisplayVO"
name="testForm"
property="poDisplayVOList"
type="java.util.Hashtable">
<tr>
<td>
<bean:write name="poDisplayVO" property="name"/>
</td>
<td>
<% String val = ((java.util.Hashtable)poDisplayVO).get("subjAreaName").toString();%>
<html:radio indexed="true" name="poDisplayVO" property="fosVO.select" value="<%=val %>" />
<bean:write name="poDisplayVO" property="subjAreaName"/>
</td>
<td>
<html:radio indexed="true" name="poDisplayVO" property="fosVO.select" value="no" /> NO
</td>
<td>
<html:radio indexed="true" name="poDisplayVO" property="fosVO.select" value="yes" /> YES

Help with JSP code to access channel properties
hi,
So I've added a new string property to the search channel (still can't figure out how to do it through the UI with ps7, see my other topic, but for now added it manually by downloading, editing and reuploading the DP).
Now how can I access the contents of that string property (which is set in the psconsole) from within the jsp files? It's probably quite simply but I just can't find the correct docs for that kind of info, so any help is appreciated.
thanks.Here's a piece of code that I use to get an Integer property from the display profile:
<dtpc:getIntegerProperty id="tabLevel" key="tabLevel"/>
<jx:declare id="tabLevel" type="Integer"/>
<% if (tabLevel.intValue() == 0 ) { %>
<jsp:include page="header.jsp" flush="true"/>
<%@ include file="primaryContainer.jsp"%>
<% showFooter = true; %>
<% } else { %>
<%@ include file="secondaryContainer.jsp"%>
<% } %>
There is also a getStringProperty tag that should work for you. The available tags for the desktopProviderContext can be found at /var/opt/SUNWportal/portals/portal1/desktop/default/tld/desktopProviderContext.tld
BTW, that's the only way I've figured out how to add new properties is by manually adding it to the DP and uploading it back. -
Help with jsp and servlets(litterature)
I'm planning on converting a asp website to jsp and I need to figure out the following:
1: servlet that gives out connection objects from a pool and manages "lost" connections to a mysql db
2: a bean that has getConnection and closeConnection that is used on every jsp page.
3: servlet/bean that can check size/dimesions/filetype on a remote url image
4: Figure out what users are logged in at every given moment. result: x users are on, these are user1, user2, user3. automatic removal when session runs out. probably need a servlet for this.
I got these books:
deitel java how to program 3rd edition
deitel advanced java 2 platform how to program
The last book has a servlet and jsp section ut I suspect that java has evolved since then so thats why I'm asking if you have any other suggestions that offer more than 2 chapters. Its really basic the stuff i have :)
Its been 3 years since I've touched java so i hope you guys can recomend jsp/servlet books that can answer these questions for me and help me get started with this project?
Thanks :)1. apache dbcp commons library.
http://jakarta.apache.org/commons/dbcp/
2. tomcat DataSource, which already has the dbpc logic incorporated into it.
http://tomcat.apache.org/tomcat-5.5-doc/jndi-datasource-examples-howto.html
3. no idea, google may help
4. HttpSessionBindingListener. This allows you to monitor when a bean (such as a User bean) is added to the session and when it is removed from the session. This way you can track yourself which users are online.

Could someone please help me with the setup process of tag libraries? I've looked on the Internet and found some instructions, but they are all for Tomcat. I'm using Jserv, and I'm not sure how to setup my environment to work with custom/tag libraries. Could someone help me by giving me some instructions or sending me to an article that could help me?
Thanks in advance!
-PVHi pvongboupha
The best source for getting to know how to set up tag libraries is the JSP specification. You can download this from :
http://java.sun.com/products/jsp/download.html
See the chapter on Tag libraries. Any J2EE compliant server will conform to these rules.
You can also see a chapter from Core Servlets & JSP by Marty Hall. This chapter is on Tag Libraries
http://developer.java.sun.com/developer/Books/javaserverpages/cservletsjsp/
Keep me posted on your progress.
Good Luck!
