How to access dataprovider through jsp syntax

I am creating an image gallery but here's my issue...
I have a database table that contains links to images on my file system. I created a dataprovider for this database table on my page so the dataprovider now returns all the image links.
Now what I need to do is create a row of thumbnails so I add a scriptlet in my jsp code where I want the thumbnail to appear. This scriptlet loops through the dataprovider and for each row it will create a standard html image tag populating the src attribute with the link from the dataprovider.
I figure creating dynamic html img tags is much easier than creating dynamic image components in the backing bean. Doing the former allows me to output the row of thumbnails exactly where I want them on the page (ie where i put my scriptlet code) and is easier to manage.
The problem is i don't know how to access the dataprovider through jsp tags and syntax. I'm sure there must be a way, can anyone help?
Thanks.

I've done this sometimes using scriplets:
<%
request.setAttribute("SOME_CONST", Constants.SOME_CONST);
%>
<c:out value="${SOME_CONST}" />But I would also be interested if anyone knows a way without those ugly scriplet..

Column Not found error while trying to access database through JSP+Java Bea

I am trying to access MS Access 2003 db through JSP using Tomcat 5.0.28.The code for accessing the database is incorporated in the bean.The JSP only calls the particular method of the bean .
Code for Java Bean:
package ActiveViewer;
import java.sql.*;
import java.util.*;
public class CompanyBean
Connection con;
ResultSet rs=null;
Statement st;
public CompanyBean(){}
public void connect()
try
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
System.out.println("Here4");
con=DriverManager.getConnection("jdbc:odbc:activeviewer","","");
System.out.println("Here1");
catch (ClassNotFoundException e)
System.out.println("Could not locate driver.");
catch (SQLException e)
System.out.println("An SQL Exception has occured :: "+e);
e.printStackTrace();
catch (Exception e)
System.out.println("An unknown Exception has occured :: "+e);
e.printStackTrace();
public void disconnect()
try
if (con!=null)
con.close();
catch (SQLException e)
System.out.println("An SQL Exception has occured :: "+e);
e.printStackTrace();
public ResultSet select(String username)
if(con!=null)
try
st=con.createStatement();
rs=st.executeQuery("select * from company where username='" + username + "'");
catch (SQLException e)
System.out.println("An SQL Exception has occured :: "+e);
e.printStackTrace();
catch (Exception e)
System.out.println("An Exception has occured while retrieving :: "+e);
e.printStackTrace();
else
System.out.println("Connection to database was lost.");
return rs;
The code for JSP that uses the above bean is:
<%@ page language="java" import="java.sql.*,ActiveViewer.* " contentType="text/html"%>
<jsp:useBean id="conn" scope="session" class="ActiveViewer.CompanyBean" />
<html>
<body>
<% String username=request.getParameter("username");
String password=request.getParameter("password");
System.out.println("username:"+username);
System.out.println("password:"+password);
conn.connect();
ResultSet rs=conn.select(username);
System.out.println("Below select ");
while (rs.next())
String dbusername=rs.getString("username");
String dbpassword=rs.getString("password");
if(dbusername.equals(username) && dbpassword.equals (password))
{ %> out.println("OK");
<% }
else { %>Invalid Username and / or Password.
<br>Clickhere to go back to Login Page.
<% }
} %>
</body>
</html>
I get the following error:
HTTP Status 500 -
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception
javax.servlet.ServletException: Column not found
though the database is not int he same folder as the jsp, the DSN is set correctly to pint to the db location.The jsp does print in stdout file:
Here4 (from connect method above)
Here 1 (from connect method above)
Below Select (from jsp)
This means that the jsp does connect to db but it gives the above error.Also the field name also matches that in the database and data is present in the db too.
All other things like creating package for bean in WEB-INF/classes,incorporating the packakage are done.
Can someone please help me with their precious advice?

Hi, I too have a problem with an SQL exception, the message is Column not found.
I'm using the sun jdbc odbc driver with access.
the first few lines of the stack trace are
sun.jdbc.odbc.JdbcOdbcResultSet.findColumn(JdbcOdbcResultSet.java:1852)
sun.jdbc.odbc.JdbcOdbcResultSet.getInt(JdbcOdbcResultSet.java:603)

sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)
I am of course sure that the column does infact exist. I can insert into the column no problems. the sql looks like this:
SELECT * FROM Members WHERE uName ='Stewart' AND encPwd='�F2C�3��h�1Y�'
Can any one tell me if there is a common cause to this problem?
Thanks

</html> I've properly set my classpath to C:\Program Files\mysql-connector-java-5.1.6\mysql-connector-java-5.1.6-bin.jar
and also put the jar file in all the WEB-INF sub folders inside C:\apache-tomcat-6.0.16\webapps (I know it had to go in one of the WEB-INF dir, but as I was not sure which one, I put the jar file in all of the WEB-INF folders)
Please, do let me know if u know how to resolve the issue. It'll be a big help.
Thanks.

I've properly set my classpath to C:\Program Files\mysql-connector-java-5.1.6\mysql-connector-java-5.1.6-bin.jarI don't think that does anything. You aren't compiling a .java file.
If you put mysql-connector-java-5.1.6-bin.jar in the directory:
apache-tomcat-6.0.x/libit will be available to all your applications.

Suggest me the best practise for accesing database by JSP page

Hi,
Can you please suggest me the best practises to connect to database through JSP page.
I am using the Struts-Portlet environment. And I have to display some contents from the database to the jsp page(view.jsp).
Please suggest.
Saurabh.

If you know how to use struts and portlets, you wouldn't be asking this question. I suggest looking into the Model-View Controller pattern to get an idea how to set up a web application, then think about how to do it in a portlet environment.

Caonnecting ms access database through tomcat5.5 query

Hi,
I have installed tomcat5.5 and jdk1.6 on my machine which has Windows server2003 as OS.
I'm not able to clearly underdstand the steps in tomcat docs for connecting to database and the changes to be made in different files.
Can someone tell me detailed and clear steps for connecting to an ms access database through jsp?
Thanks in advance for your suggestions.

I'm not exactly sure why you have this problem. I know that the Microsoft SQL Server driver has a parameter "readOnly=false". Check your DB2 docs to see if you need to set a flag like that, too.
Maybe it has to do with transactions and auto commit. See if DB2 assumes autoCommit true or false. Maybe you have to explicitly commit your INSERT.
Maybe you're writing to one database and opening another. Make sure that's correct.
There are other suggestions that I'll offer.
You do all that work with a database in a constructor? Bad idea.
You've got database and UI stuff all mingled together. Ever heard of MVC separation?
Be object-oriented - start by designing an object to encapsulate all those items you're trying to INSERT.
Then write a Data Access Object (DAO) that does CRUD operations for that object. Test these thoroughly, preferrably with JUnit, until they're 100% perfect.
Then have a separate UI that instantiates these objects and calls their methods. The persistence layer shouldn't know about UI stuff, and the UI shouldn't need to have any persistence code in it.

How to connect a PDF form to SQL server database through web service?

Hi,
I'm new to LiveCycle designer. I have designed a PDF form in LC designer ES2, which suppose to take a personnel number and retrieve the personnel information from a SQL server database. Currently its working fine with XML data and a search button, but I need to securly connect to a database through web service. I know how to connect to a wsdl file through designer.

I really appreciate your help and advice.

when should you close the connection? when you're done with it.
how should you close the connection? like this: conn.close();
that said, doing this in a JSP page is bad form and not recommended
JSP's typically don't contain ANY business or data logic

If you do the redirect with javascript, the user cannot resubmit his login when he presses the refresh button. When he does press refresh, he only refreshes the redirect, not the form post that was before it. When he presses back the redirect will also kick him back in stead of going back to the login page. A simple javascript redirect page would look like this:
<html>
<body onload="document.location.href='myhtmlpage.htm';">
</body>
</html>But that is only if you care about resubmits of course.

How to Connect MySQL Database Through JTable?

Hi,
How to Connect MySQL Database Through JTable? anyone of u knows these concept please send me coding of that Part..
Thanks,
Guru..

Start by reading the tutorials. There's a section on Swing which shows you how to use tables and a section on JDBC which shows you how to use SQL.
And you can always search the forum as well since there are working examples of both posted on the forum.
If you need further help with a specific problem then you need to create a [Short, Self Contained, Compilable and Executable, Example Program (SSCCE)|http://homepage1.nifty.com/algafield/sscce.html], that demonstrates the incorrect behaviour.
Don't forget to use the [Code Formatting Tags|http://forum.java.sun.com/help.jspa?sec=formatting], so the posted code retains its original formatting.

How to get the data from mysql database which is being accessed by a PHP application and process the data locally in adobe air application and finally commit the changes back in to mysql database through the PHP application.

How to get the data from mysql database which is being accessed by a PHP application and process the data locally in adobe air application and finally commit the changes back in to mysql database through the PHP application.

If the data is on a remote server (for example, PHP running on a web server, talking to a MySQL server) then you do this in an AIR application the same way you would do it with any Flex application (or ajax application, if you're building your AIR app in HTML/JS).
That's a broad answer, but in fact there are lots of ways to communicate between Flex and PHP. The most common and best in most cases is to use AMFPHP (http://amfphp.org/) or the new ZEND AMF support in the Zend Framework.
This page is a good starting point for learning about Flex and PHP communication:
http://www.adobe.com/devnet/flex/flex_php.html
Also, in Flash Builder 4 they've added a lot of remote-data-connection functionality, including a lot that's designed for PHP. Take a look at the Flash Builder 4 public beta for more on that: http://labs.adobe.com/technologies/flashbuilder4/
