HELP with mySQL!!
Im trying to connect to Mysql using MySQL Connector/J , but always found this error message when executing it
"java.lang.ClassNotFoundException: com.mysql.jdbc.Driver".
i have the JAR file in C:\JDBC and C:\jdk1.5.0\jre\lib\!
i set my CLASSPATH like below
C:\jdk1.5.0\jre\lib\mysql-connector-java-bin.jar;c:\jdk1.5.0\lib\tools.jar;c:\jdk1.5.0\lib\dt.jar;C:\Program Files\Apache Software Foundation\Tomcat 5.5\classes;C:\Program Files\Apache Software Foundation\Tomcat 5.5\lib;C:\JDBC;
codes are below
import java.sql.*;
public class main {
/** Creates a new instance of main */
static final String JDBC_DRIVER = "com.mysql.jdbc.Driver";
public static void main(String[] args) {
try {
Class.forName(JDBC_DRIVER).newInstance();
System.out.println("Driver loaded");
} catch (Exception ex) {
System.out.println(ex.toString());
HELP PLEASE!!!!!!!
Look at some of these I got from the search - I am sure you will determine the problem.
http://search.sun.com/search/developers/index.jsp?and=%22java.lang.ClassNotFoundException%3A+com.mysql.jdbc.Driver&nh=10&phr=&qt=¬=&field=&since=&col=devforums&rf=0&Search.x=15&Search.y=8
It looks like a classpath problem.

Help with mySQL Connection string
Here is hoping someone can help & once I get it down I promise I'll post all my work on this list so some other newbie can benefit.
I'm simply trying to run a very very straightforward JDBC test with mySQL & I keep getting the "Server configuration denies access to data source" error. But before you tell me that I must simply look at what my mysql.db & mysql.user table allows - I'VE TRIED THAT. I realize that the error is probably there somewhere - but I can't see it.
I've tried connecting with 2 different accounts - the provided "root" & a user I created "deep" to 2 different databases the provided "test" & "testdb" which I created) . Here is what mysql says about the two different databases
mysql> select * from db;
Host | Db | User |.......
-----+------------+-------
| % | test | | ......
| % | test\_% | | ........
| localhost | testdb | deep |........Note that "root" should have access to "test" & deep@localhost should have access to "testdb" right?
So here are all the connection strings I have tried - all return the same error below
Connection conn = DriverManager.getConnection(
"jdbc:mysql://localhost:3306/test", "root", "mypass"
// "jdbc:mysql://localhost:3306/testdb", "deep", "mypass"
// "jdbc:mysql://localhost/testdb?user=deep&password=mypass"
// "jdbc:mysql://localhost/testdb", "deep", "mypass"
// "jdbc:mysql://localhost:3306/testdb?user=deep@localhost&password=mypass"
// "jdbc:mysql://localhost:3306/testdb?user=deep&password=mypass"
// "jdbc:mysql://localhost/testdb", "deep@localhost", "mypass"
// "jdbc:mysql:///test", "root", "mypass"
// "jdbc:mysql://localhost/test", "root@localhost", "mypass"

Need help with MySQL connection error _mmServerScripts
Trying to create insert a recordset I got the message:
"The files from the _mmServerScripts folder are for the server model PHP-MySQL. You try to connect to a database using a different server model .Please remove this folder outside the Dreamweaver environment on both local and testing machines and try again."
I've searched the net and have seen this message hunting people since dw8...
I could not find a "cure".
Things to notice:
0 - Yes the whole thing is apache/php/mysql... just DW thinks it's not.
1 - Both the connection and the Recordset actualy works. I have a whole site based on this connection and the recorsets I've created manualy based on it.
2 - It does not matter if we erase or not the _mmServerScripts folder the message stands still allover.
3 - The problem seems to show up when you split servers...
3.1 - If I test in a WAMP environment where apache and mysql are in the same machine I can use DW to create data objects for me.
3.2 - If I test in my real test environment which have web server and db server separated from each other then I can't use DW to create data objects, see bindings, behaviours etc... all I get is this message.... while the code itself runs fine anyway.
Does any one already knows how to work around or fix this?
Thanks,
JulioThanks PZ,
Yes everything is fine with the site definition.
everything works. I can upload, run, test all ok.
The only thing that does not work is to insert any sort of data object through DW interface. If I declare my reordsets by hands or even If I use the ones DW created in my local test server all works fine.
Then if I use the site definition and try to see any bindings or create a recordset or create a new connection using dw... then the messages come up and dw can't go any further in that task.
By spli servers I mean one phisical linux server with apache/php but without mySQL + one physical Linux server with mySQL but without apache/php.
So when I use a site definition that points either to a WAMP or LAMP i.e. when everything is in the same machine DW goes happy and does whatever it's asked to do.
When I try that on the real mccoy environment (with the two separated servers)... It looks like DW gets confused... -
Need Help with mysql admin for Mac
Hello all.
I am new to cold fusion and databases all together. Infact I
am doing an online tutorial to get me started, my problem is the
tutorial really just scratches the surface for the mac side and in
some cases sorta explains how to do but no visual help and I am
very visual.
I am searching for software that is really idiot proof to
start my knowledge with then make the transition when I learn more
and more to hard coding. The tutorial suggests Navicat for Mysql
admin and it is nice but he is setting up basic databases in Access
which looks really easy and I am trying to follow along with
navicat but I am just not getting it specifically when it comes to
setting up relationships between tables. Can I use a software like
FileMaker Pro and just convert to mysql or is their other software
that makes it a little more easy to understand how to set up
relationships like access does.
I am totally new to this stuff and I am looking for the
easiest product to use. Thanks again for your help and time.
ChrisAs for the database part, before you write your first query,
you should become grounded in the concepts of data modeling. Then
find a good source (book, books-on-line, etc. ) for the particular
"flavor" of SQL used by your database of choice, then start writing
your queries. Data model first (entities, relationships,
attributes), then SQL.
Couple of fairly good online tutorials for data modeling.

Help with MySQL/PHP Connection
Hi,
I'm making a site that requires the storage of information via MySQL. I've set up my testing server, and it connects fine. When I try to add a MySQL connection, however, I keep getting the "HTTP Error Code 404: File Not Found" error. I've tried using both the MySQL server provided by my web host and one hosted on my own computer (using "localhost" as the server), but both give me the same error. The error box says that perhaps:
1) There is no testing server running on the server machine.
2) The testing server specified for this site does not map to the http://**mywebsite**.com/_mmServerScripts/MMHTTPDB.php URL. Verify that the URL Prefix maps to the root of the site.
I'm certain it's not #1, because both of my MySQL servers work fine outside of Dreamweaver. But I'm not quite sure what #2 is saying. Any help?
Thanks in advance.nickf77 wrote:
I have my testing server set up at my FTP account that came with my hosting package. Should it not be?
It's not ideal, but you can do it that way. The principle is still the same.
When using a remote connection, the value of Host directory is the same as you use for FTP connections to your remote site. In many cases, this is left blank, is simply a forward slash, or is something like public_html. In any event, it's the root level of your website.
URL prefix is also the root level of your site, but expressed as a URL: http://www.example.com/.
Host directory and URL prefix must both point to the same place. The first is a path, the second is a web address. -

}Thank youA blank page usually indicate that an exception is been thrown but cannot be displayed because the response is already started/committed/processed. Just read the appserver's logs as usual for the details.
Your servlet class does way too much. You're mingling all the processing steps together in one class. This is simply asking for trouble. Use a DAO class for accessing the DB. Use a JSP file for presentation. Use a business object to process the input/output data. Use a servlet for controlling the request. To start off, you may get some ideas out of this article and the JSP/Servlet follow-up: [http://balusc.blogspot.com/2008/07/dao-tutorial-data-layer.html].
Oh, your JDBC code is not safe against SQL injection attacks either. -

Need help with mysql-connector-j setup!
I have downloaded and installed Tomcat 5.5 and MySQL Server 5.0 and have both up and running. I then downloaded the MySQL-Connector-J and the folder is located at:
C:\Program Files\Java\jre1.5.0_06\lib\ext\mysql-connector-java-3.1.12
My JSP code looks like this:
<%@ page contentType="text/html; charset=iso-8859-1" language="java" import="java.sql.*" errorPage="" %>
<%@ page import="java.net.*" %>
<%@ page import="java.util.*" %>

<%@ page import="java.sql.*" %>
<%
try{
Class.forName("com.mysql.jdbc.Driver").newInstance();
catch (Exception E) {
out.println("Unable to load driver. " + E);
%>And I am getting the folowing error:
java.lang.ClassNotFoundException: com.mysql.jdbc.DriverNow, before anyone tells me to go read other posts, I have already done this and I have tried changing my classpath with no luck. I have tried these locations as my classpath:
C:\Program Files\Java\jre1.5.0_06\lib\ext\mysql-connector-java-3.1.12
C:\Program Files\Java\jre1.5.0_06\lib\ext\mysql-connector-java-3.1.12\mysql-connector-java-3.1.12-bin.jar
Neither of which seem to work. Can anyone figure out what's happening here?Ok, I copied it to the <tomcat dir>/common/lib, but I copied the entire folder (which I'm assuming is necessary), with no luck. So, now the location is:
C:\Program Files\Apache Software Foundation\Tomcat 5.5\common\lib\mysql-connector-java-3.1.12\mysql-connector-java-3.1.12-bin.jar
Any other suggestions?
Thanks.

Read the API docs and the JDBC Tutorials for the proper way to use a PreparedStatement. It may "work" to add the quotes, but it is definately not the right way to do it. What happens if the city entered contains an apostrophe? Your statement will be broken again. Like I said, use a PreparedStatement and use it right. -
I've got a db that contains various attributes of particular
items... very similar to a db of a DVD library, for example...
Director, Year of Release, comments, release date... etc.
How do I structure the query in Dreamweaver (CS3) to tell the
db to return ALL results for a field if it is submitted blank? As
in, if a user didn't specify a Director, then it should not filter
by that column and return ALL directors instead?
In the advanced recordset dialogue I have the variables set
to submit the run-time values from the form, but I don't know what
to put in the "Default Value" field...
I know this should be very simple, but I just can't get it to
work... I tried %, but that's not doing it. (also, I tried
searching the forum, but the search function is not working
properly right now.)
Any help is appreciated.I am completely self-taught to this point... testing the
fields for content and adjusting the WHERE clause accordingly is a
bit beyond my level. However, if anyone knows of any good content
on the web that can help me get it that would be helpful... i just
need to see a couple examples of this in action in order to
comprehend it.
I know that this is (or should be) an incredibly basic
function of DB query... this shouldn't be THAT hard to find... I've
googled and come up short... -
Help with MYSQLi Query and WHILE statement

Not sure what is wrong here but the same record is printed in the while loop 11 times (the amount of records in the table).

As I see it, the way you have suggested is just rearanging things right?
here is a screenshot of the outcome:
And here is the improved code:

<?php

$row_count = $result->num_rows;
//Create Variables

Some help with MySQL fetch size
To get the number of rows returned by a MySQL query, I do this:
public static void main(String[] args) throws Exception
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection connection = DriverManager.getConnection(url, user, password);
Statement statement = connection.createStatement();
String query = "SELECT * FROM users";
ResultSet rs = statement.executeQuery(query);
int number = statement.getFetchSize();
connection.close();
System.out.print(number);
}which returns 0 even though I have 7 users. What am I doing wrong?Jamwa wrote:
Sad to say but
Retrieves the number of result set rows that is the default fetch size for ResultSet objects generated from this Statement object. Is a bit ambiguous to me.When trying to look something up in the API, it's a good idea to keep your eyes open. I scrolled up half a screen
from getFetchSize to setFetchSize, and Lo! and behold:
<quote>
If the fetch size specified is zero, the JDBC driver ignores the value and is free to make its own best guess as to
what the fetch size should be. The default value is set by the Statement object that created the result set.
</quote>
Now I understand what a fetch size of 0 means. Thank you, API! -
OT: Help with MySQL/PHP line (SQL syntax)
I have this now -
$colname_rsPassword = $_POST['password'];
$query_rsPassword = sprintf("SELECT contactFName,
contactLName,
contactPassword, contactEmail, contactRecord FROM
tblcontactdata WHERE
contactPassword = %s", GetSQLValueString($colname_rsPassword,
"text"));
How would I change that to include $_POST['LName'] and
$_POST['FName'] (as
posted from the form) in the WHERE clause?

==================I did it another way -
GetSQLValueString($colname_rsPassword, "text"),
$_POST['fname'],
$_POST['lname']);
goes to this -
GetSQLValueString($colname_rsPassword, "text"),
"'".$_POST['fname']."'",
"'".$_POST['lname']."'");
Woiks!
