Java MySQL ResultSet Help

How do I read the result of query -
"SELECT unix_timestamp(date_format(now(), '%Y-%m-%d %H') )"
from Java Result Set to a String variable in Mysql..
I tried -
Connection conn = getConnection( );
Statement s = connection.createStatement();
ResultSet rs = s.executeQuery( "SELECT unix_timestamp(date_format(now(), '%Y-%m-%d %H') )" );
String result = resultSet.getString( "unix_timestamp(date_format(now(), '%Y-%m-%d %H') )");
I don't get the value in result..rather I get the exception...My resultSet comes as not null from database.
Thanks!

You are using one variable when executing query and using another variable when accessing data. See the bolded values.
Connection conn = getConnection( );
Statement s = connection.createStatement();
ResultSet rs = s.executeQuery( "SELECT unix_timestamp(date_format(now(), '%Y-%m-%d %H') )" );
String result = resultSet.getString( "unix_timestamp(date_format(now(), '%Y-%m-%d %H') )");

JDBC Java- mysql problem help!

Hi, I wnat to connect to mySQL fromo Java, I followed all the instructions from the mySql web page, yet I havent been able to do it, when I compile the java progrm I keep getting class not found exceptions, I am using Fedora Core and Java was already installed-well I chose to install it when I installed the operating system, the point is that the paths are all assigned by he system not by me.
WHat can I do?, Ive been trying over andover again with no results, hopefully somebody can help, I tried to include all the configuration in this email,
thank you
my java program is the following:
t.java
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class t {
public static void main (String[] args) {
System.out.println("Hello, world!\n");
Class.forName("com.mysql.jdbc.Driver");
when I javac t.java
I have the following error
4. ERROR in t.java
(at line 11)
Class.forName("com.mysql.jdbc.Driver");
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Unhandled exception type ClassNotFoundException
when I comment out the Class.forName the hello world rogram runs fine

Thanks duff,
The driver seems to be found
when I run
public class t {
public static void main (String[] args) {
try
System.out.println("Hello, world!\n");
Class.forName("com.mysql.jdbc.Driver");
System.out.println("MySQL Driver Found");
catch (ClassNotFoundException e)
System.out.println("MySQL Driver NOT Found");
e.printStackTrace();
I feel somehow ive been focusing in the wrong side of the problem due to my ignorance in Java. Please help me to understand, the reson for which ithe runtime was telling me that there was an unhandled exception was because it is a requirement to handle all exceptions of this kind? why wouldnt it cmplain if I jst did the hello world without any exception handling, maybe because it is a requirement in the Class.forName...
the other question is, is the message I was obtaining completely independent of the fact that the class was or was not found?
Maybe, I should go with these questions to the newbies forum...
thanks

Java mysql ResultSet - how many rows

Hi
As a beginner java dude I'm trying to work with java on my mysql database instead of using perl (which works fine by the way). BTW this is not an apple specific question.
I have properly managed to connect to my database and executa a query which returns a ResultSet object. By using the next() method I would like to populate an array with the results of my query using a while loop. All of this works fine. One problem persists however. I would like to know how many rows my query has so I can creat my array with the correct number , i.e if the query has 10 rows then the array should be String[] Array = new String[10].
But i can only loop through the ResultSet once as it appears to be detsroyed after that. I have solved the issue by making two identical statements and I use one with getRow() in a while loop so I can create an array with the correct variables, and the other to loop through and populate the array.
It seems to me there must be a better way to check how many rows a query returns ... i mean if I take the original query an put it through
int nr = 0;
while (rset.next()) {
nr = rset.getRow();
String[] Data = new String[nr];
and then do
while (rset.next()) {
int count = rset.getRow();
--count;
int idnr = rset.getInt("One");
String name = rset.getString("Name");
Data[count] = idnr + " " + name;
the the last while returns null results.
How can withdraw the number of rows from the ResultSet and still use that same ResultSet in the last while loop? I have a feeling i'm missing something very elementary here.. but being new thats to be expected.
Thanks

Darn, just after I posted this I was struck by lightning and found an answer. The ResultSet isnt destroyed its just that the marker is at the end efter looping through a while loop, so if you want to loop again you have to the the marker to move to the absolute beginning.. thsi can be done using ResultSet.beforeFirst() which nice and neatly pops the marker back to its initial state.
Sorry for bothering everyone.

Image size and mime type.. non-java guy needs help

Image size, mime type.. non-java guy needs help
Im not at all familiar with java so this is really weird for me to work out. I?ve been doing it all day (and half of yesterday).
Im trying to write a custom clodFusion tag in java that gets the width, height, size and MIME types of a given file. I?ve been trying to get it to work on the command line first. I can get the width and height but cant get the size and the MIME type.
Here is what I got
/*import com.allaire.cfx.*;*/
import java.awt.image.renderable.*;
import javax.media.jai.*;
import com.sun.media.jai.codec.*;
import java.io.*;
import java.util.*;
public class ImageInfo {
private RenderedOp image = null;
private RenderedOp result = null;
private int height = 0;
private int width = 0;
private String type = "";
private String size = "";
public void loadf(String file) throws IOException
file = "80by80.jpg";
FileSeekableStream fss = new FileSeekableStream(file);
image = JAI.create("stream", fss);
height = image.getHeight();
width = image.getWidth();
System.out.println(height + "\n");
System.out.println(width);
System.out.println(type);
public static void main(String[] args) throws IOException {
ImageInfo test = new ImageInfo();
test.loadf(args[0]);
can anyone please help me out to modify the above so I can also print the mime type and the file size to screen.
thanks for any help

any suggestions?

IMac: Install Java 7 need help!

Hello, I've an iMac with the newest software version, I want to install java 7 on it for a game server, but when I download it from java.com and I install it and start the server, it still says: Computer on java 6, update to 7 to run server. I already tryed to install with Terminal and direct acess to System Library, it shows that java 7 is installed, but I have to delete java 6. When I delete all java versions, apple says I have to install java SE6, what isn't java 7 but java 6! Help please!!!

The Oracle JRE is only a web plugin. If you need server-side Java, you'll have to use the Apple-supplied Java 6 runtime, or else the Oracle JDK (which is not a drop-in replacement for Apple's Java.) If your server application depends on Java 7, you'll most likely have to run it on another operating system.

I can't open ibooks. There was a screen pop up about java se. Help please.

Hi there ajsupprt,
It sounds like you may need to update the version of Java installed on your computer. Take a look at the article below for more information.

Oracle.jdbc.driver.oracleResultSet Vs java.sql.ResultSet

Hi all
Could any one got any idea on this problem...
My application program is forced to use both Java Result Set(java.sql.ResultSet) and Oracle ResultSet(jdbc.driver.oracleResultSet).
This on javac get compiled and is working fine....
But when i try to compile with vbjc(visibroker-java compiler)... it failes to compile...
throwing ...
.."The method oracle.jdbc2.Blob getBlob(int) declared in class oracle.jdbc.driver.OracleResultSet cannot override the method of the same signature declared in interface java.sql.ResultSet. They must have the same return
type."

Hi Prowzen,
Ur reply was much userful, which gave me a direction to prob into... Thank You Very MUCH.
I relpaced
BLOB blob = ((OracleResultSet)rs).getBLOB(int);
with
oracle.sql.BLOB blob =(BLOB)rs.getObject(int);
So eliminating usage of OracleResultSet, the conflicts got cleared...
Keep writing...

Displaying Picture in a Java APPLICATION please help!!

I have been trying to write a method that Displays a .jpg file when called. However I have not gotten far, every book I have tell you how to display pictures in an applet but not an application. I did find some code that is supposed to be for an application, but It does not compile right. Any help would be apprecidated!
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class PictureIt{
public void makeImage() {
//***Image Output Stream
String imgFile
= "d:\\temp\\TestImage.jpeg";
out = new FileOutputStream(imgFile);
BufferedImage image = null;
image = (BufferedImage)createImage

ball = kit.getImage("pic1.gif");
public void paintComponent(Graphics comp) {
Graphics2D comp2D = (Graphics2D) comp;
comp2D.drawImage(ball, 20, 20, width1, height1, this);
sound class is the container JFrame here it is
import javax.swing.*;

Java mysql connection

Hi,
Can anybody tell me how can I make the java-mysql JDBC connection using IDS Server ( type 3 driver )
this is the only driver which bypass proxy/firewall
if any one use this driver before pls give me more information about it.

Well, first you have to obtain a type 3 driver for MySQL. I don't know if such a driver exists.
Assuming one does, you'd need a properly configured server.
Once you've got that, the Java code should be identical to that for any other driver.

Can i download java for my ipad, the problem is i open glovis.usgs from my ipad, but i can't see the full page, cause the page need a java...help me please

Can i download java for my ipad, the problem is i open glovis.usgs from my ipad, but i can't see the full page, cause the page need a java...help me please

Nope. The iPad (and iPhone and iPod touch) cannot execute Java applets. It's a limitation in iOS from the beginning (just like lack of Flash). You will either need to use a desktop computer or access a desktop computer via RDP or VNC to access that page on iPad.mIn short: there is no native way to use a Java applet on iOS.

Problems implementing java.sql.ResultSet on AbstractTableModel

Hi java Gurus !!
I have a trouble implementing interface java.sql.ResultSet on javax.swing.table.AbstractTableModel. The AbstractTableModel class defines a method like
this:
int findColumn(String column)
while the java.sql.Resultset defines a method as follows:
int findColumn(String column) throws SQLException.
the compiler gives me the following error:
"Error #: 462 : method findColumn(java.lang.String) in class inducontrol.Untitled1 cannot override method findColumn(java.lang.String) in class javax.swing.table.AbstractTableModel, overridden method does not throw java.sql.SQLException at line 213, column 14
How can I solve it?
thanks a lot !!!!

Hassen is correct, it seems that you mix two different things.
Can you show code excerpts so we can give you some tips ?

I need to learn how to use all about java & mysql...help me!

I have a situation here, I need to learn how to use java with mysql
. Can I connect to a MYSQL DB with servlets?
how can I build an e-mail server with java (no matter how difficult)
please, I need help, and I really apreciate your help.
thank you very much!!

I have a situation here, I need to learn how to use
java with mysql
. Can I connect to a MYSQL DB with servlets?Yes... documentation to help you connect to any database can be found at http://java.sun.com/products/jdbc. To connect to MySQL, you'll need drivers (sourceforge.net), and the specific connection URL for those drivers will be included in the documentation.
how can I build an e-mail server with java (no matter
how difficult)If you're fairly new to JSP/Servlets, you may be in over your head here, since an email server is no easy application to code. Here's a link to the source code for the JAMES project... Apache's Java email server... maybe you can find some useful information there...

JAVA + MYSQL + ACCESS + ENCODING!!! help needed here!!!!

i have to migrate some data from access to mysql. however, i have some japanese characters in the access table and whenever i am done w/ migration and open the mysql table, i see bunch of ?????? instead japanese character. since im now working for a japanese company, this pc is in japanese eviorioment.
i set mysql table to use utf8. does anyone here know whats going wrong? i guess there is something to do w/ encoding stuff. please help!!!
here is some more information:
java1.5.1, access2003, mysql5.1 and japanese xp

This is the third thread you have opened on the same problem within the last couple of days, and you have not provided any more information than in the first one that would let people figure out what you are doing and thus help you.
In the first thread you opened it seems you had gotten to the point of realizing that you couldn't insert Japanese characters correctly in your mysql database, right? So it seems that the problem is simply with your mysql configuration and/or the way you interact with it from Java.
So, to narrow the problem down further:
1. Can you insert Japanese directly into mysql (not from Java) and get them rendered correctly? That would indicate your DB is configured correctly.
2. What is the code you use to insert Japanese characters into mysql? (start with hardcoded Japanese, don't mix the Access migration into this yet)
