JDBC connecting with MYSQL

i has install JAVA 2 SDK and MYSQL to do my DBMS, i try to making connection between JAVA and MYSQL, after complie and run java file, i got the Error: java.sql.SQLException: No suitable driver

have you include the jdbc driver in your classpath
try put the jar of jdbc driver in your project 's lib foler
or add it to your system's classpath
and it may work well
good luck

I think you should give a username and password. How can it look up a password without a username? Better GRANT the right permissions, too.
Read the MySQL docs a bit more closely. Your path isn't the way to go.

A few facts:
1. You NEED to have the JDBC driver jar on the Java classpath
2. You don't NEED to have the jar on the Windows classpath
3. You don't NEED to 'override' the Windows classpath - you can just append the JDBC jar to it
Just use #3 above - edit the Windows CLASSPATH environment variable and add the JDBC jar to it. At it at the start and follow it with a semicolon. Or at it at the end AFTER adding a semicolon.
Or specify the CLASSPATH on the command line when you launch Java. Use the '-cp' or '-classpath <class . . >' options. Just type 'java' at the command line to see the list of parameters that can be used.

Problem in establishing connection with mysql 5.0

Hi,
I am using JCAPS 5.1. I tried to insert data to mysql database table.
But i got following error
java.sql.SQLException: Error in allocating a connection. Cause:
Physical Connection doesn't exist.
My intention is to read file in which data are comma seperated and to
populate those values to a mysql 5.0 database table.
Sample DATA in file [test.txt]
111,gg,23,MFG
112,hh,24,MFG
113,ii,25,RETAIL
114,jj,26,IT
Database table: employee
eno,ename,eage,edept
While creating JDBC OTD there is no problem in establishing connection with database. But after deploying i got above error.
I have used Mysql 5.0 Connector/J JDBC driver. Added JDBC driver jar files to following directories as required.
1) C:\JavaCAPS51\logicalhost\is\lib
2)C:\JavaCAPS51\logicalhost\is\domains\test\lib
Steps i have followed as per JDBC-ODBC -eway user guide doc.
1) Created USerDefined OTD and added necessary fields
2) Created JDBC OTD.
3) Created JAVA collaboration and do business process for inserting
4) Mapped all components by creating in Connectivity MAp
5) created necessary external systems in envrionment explorer.[JDBC External System and File External System]
6)Created Deployment profile
5) Deployed it.
After deploying it gives error as
java.sql.SQLException: Error in allocating a connection. Cause: Physical Connection doesn't exist
Please let me know the solution for problem.

In the environment definition,
-> External Application JDBC
-> Properties
-> Outbound JDBC Connection
You have the database URL in the "DriverProperties" field
Valid URL would be : jdbc:mysql://localhost:3306/caps
!! The doc says that this field is optional !! Seems to be an error in the doc:
Hope this helps

Connectivity with MySQL in Windows

How can I connect JSP with MySQL in Windows?
          I Tried out the following code but It did not work
          Class.forName("org.gjt.mm.mysql.Driver");
          Connection cn = DriverManager.getConnection("jdbc:mysql:///test");


I think you missed the IP address for your MySQL server machine.
          If it's on the same computer, try this:
          jdbc:mysql://localhost/test

Create a simple connection with mysql

hello
my name is edvanio i am from brazil.
i'd like to connect one program in Java with mysql for insert, delete and update one simple base ex. teste with nome and fone.
thank , bye

here's a couple of sites
http://www.javacoding.net/articles/technical/java-mysql.html
http://www.developer.com/java/data/article.php/3417381
I recently installed MySQL (just to see if I could get a working program to run)
these were the steps
1. downloaded MySQL
2. downloaded the connector file
3. unzipped/installed MySQL
4. unzipped the connector file
mysql-connector-java-3.0.17-ga-bin.jar
copied the jar file into this directory
C:\Program Files\Java\jdk1.5.0_03\jre\lib\ext
5. opened MySQL, using the code from Gamelan
create the db JunkDB
created the user, permissions, password
6. combined the code from both sites (code follows)
and it worked OK
import java.sql.*;
class MySQL_Test
public MySQL_Test() throws Exception
    testDriver();
    Connection con = getConnection();
    executeUpdate(con,"CREATE TABLE test(id int,text varchar(20))");
    executeUpdate(con,"insert into test(id,text) values (1,'first entry')");
    executeUpdate(con,"insert into test(id,text) values (2,'second entry')");
    executeUpdate(con,"insert into test(id,text) values (3,'third entry')");
    executeQuery(con,"select * from test");
    executeUpdate(con,"drop table test");
    con.close();
protected void testDriver() throws Exception
    try
      Class.forName("com.mysql.jdbc.Driver");
      System.out.println("MySQL Driver found");
    catch(ClassNotFoundException cnfe)

Create database connection with Mysql

Hi, all:
inside JDeveloper, i try to create a database connection for Mysql (third party
JDBC driver). I input all needed parameters into
JDeveloper database connection dialog, and test connection, the error message
says 'Unable to find driver org.gjt.mm.mysql.Driver". The jar file contains driver
is listed in system classpath, and Mysql and MM-Mysql JDBC driver are tested with
other applications and there is no problem.
So, what i should do to create such a connection ??
Any help will be appreciated. thank you in advance.
kevin.

The connectio URL could look like this:
(leave the User-, Password-, and Role-fields, in the tab before, empty)
Java Class Name: org.gjt.mm.mysql.Driver
URL: jdbc:mysql://localhost:3306/test?ultradevhack=true&?user=myuser&?password=mypassword

Connecting with mysql

hello
how can i create a connection to mysql and postgresql databases in jdbc. without using odbc.
thanks.

You need to use a different driver. I assume you're using the jdbc-odbc bridge driver.
For mysql, get the mm.mysql driver at http://mmmysql.sourceforge.net/
For postgresql, go to http://jdbc.postgresql.org/
I've only used the mysql driver, so I don't know the details of how to use the postgresql one.
In general, you will have to do the following:
1. download the jar file and put it in your classpath
2. change the connection url string to conform with the format in the driver documentation.

Jakarta-tomcat-3.3.2 connection with mysql-4.1.12a-win32

how do i connect to mysql using tomcat?
i've set the class path = ".;D:\j2sdk1.4.2_08\jre\lib\ext\mysql-connector-java-3.1.10-bin.jar;"
without quotes
i've copy the mysql-connector-java mysql-connector-java-3.1.10-bin.jar into the mentioned directory = "D:\j2sdk1.4.2_08\jre\lib\ext\"
and my computer's mysql 's service is starting since my computer restart [i've checked it by right click desktop toolbar->Task Manager->Processes->mysqld-nt.exe..
and i've used the code from :
http://www.stardeveloper.com/articles/display.html?article=2003090201&page=4
to test if my connection is active, my JdbcExample1.java file is located at D:\jakarta-tomcat-3.3.2\webapps\ROOT\WEB-INF\classes\com\example, so my source code is :
package com.example;
import java.sql.*;
public class JdbcExample1 {
public static void main(String args[]) {
Connection con = null;
try {
Class.forName("com.mysql.jdbc.Driver").newInstance();
con = DriverManager.getConnection("jdbc:mysql:///test", "root", "nothing");
if(!con.isClosed())
System.out.println("Successfully connected to MySQL server...");
} catch(Exception e) {
System.err.println("Exception: " + e.getMessage());
} finally {
try {
if(con != null)
con.close();
} catch(SQLException e) {}
when i compile the file using javac, it's fine, when i run it using java, it shows me this error:

what have i missed out? anyone can u please help me? is my coding or setting in-accurate? thanks for reviewing my topics too

I'm not sure why you have mentioned Tomcat, but you need to run the class with something like:
java -classpath .;D:\j2sdk1.4.2_08\jre\lib\ext\mysql-connector-java-3.1.10-bin.jar com.example.JdbcExample1If you've correctly set the CLASSPATH environment variable then you can leave out the -classpath command line argument. Notice that you must specify the package of the class too.
To compile this all correctly, you should do something like:
mkdir classes
javac -d classes JdbcExample1.javaand then run with
java -classpath classes;D:\j2sdk1.4.2_08\jre\lib\ext\mysql-connector-java-3.1.10-bin.jar com.example.JdbcExample1

Slow database connection with mysql

I am using MySQL Server 5.0 as my backend and java1.5 as my front end for the GUI. The following statements I use to connect to MYSql.
Class.forName("com.mysql.jdbc.Driver").newInstance();
String url = "jdbc:mysql://localhost:3306/mysql";
The database access seems to be very slow.
I have a data file with about 3000 lines. The parser reads the file one line at a time, formats an insert query and calls executeUpdate. The process takes more than 2 minutes.
What is slowing down my process? Please help
Thanks

ThanksHi,
1. Are you opening and closing the database connection ,During inserting every record from data file?
If so, please avoid opening closing connection for each query execution.
Because , opening and closing the database connection is a time consuming one.
You should open all the required database connections, before you use them or use
Database connection pooling if your application is sucah a big one.
2. Try PreparedStatment instead of Statement. Because Prepared statment query is
compiled and stored into Cache. so if you are executing the same query again and again, the compiled query will be picked up from cache, by replacing with new
parameters
3. Check the logic you used to pick record from datafile and insert into database .
4. Check your RAM size , if you installed database and jvm on same machine.
if so , increase your RAM size.
thanks,

Connection with mysql

Hi all!
I am trying to connect MySql using connector mysql-connector-java-3.0.17-ga-bin.jar. Driver is loaded but it is
not getting connected. Though in Windows it works fine but give problem in linux fedora 6. I am using connection string
jdbc:mysql://localhost:3306/test with username and password.
code --------
System.out.println("before driver loading");
String url="jdbc:mysql://localhost:3306/test";
//load JDBC driver
try
Class.forName("org.gjt.mm.mysql.Driver");
System.out.println("driver loaded");
catch(Exception e)
System.out.println("Uable to load driver.");
try
System.out.println("Trying to make connections");
Connection conn=DriverManager.getConnection(url,"username","password");
System.out.println("Database connected");
Statement stmt=conn.createStatement();
ResultSet rs=stmt.executeQuery("select * from table");
while (rs.next())
System.out.println(rs.getString(1));
catch (SQLException e)
System.out.println("SQLException:"+e);
It shows following error-
SQLException:java.sql.SQLException: Unable to connect to any hosts due to exception: java.net.SocketException: java.net.ConnectException: Connection refused

Whats wrong?

That is an ancient Driver (both classname and jarfile). Download a new driver and use "com.mysql.jdbc.Driver".
That is beside the point though. The real point is that it seems as though your mysql is not configured to accept network connections, or it is configured for a different port from the default 3306. Check your configuration, see the documentation for details.

Microsoft SQL Server JDBC Connection with Enterprise

I'm trying to establish a JDBC connection to a SQL Server 2005 database server within XML Publisher Enterprise with no luck. What I have defined is:
url = jdbc:sqlserver://servername where servername is the database server name
Database Driver Class = com.microsoft.sqlserver.jdbc.SQLServerDriver
And I have placed the sqljdbc.jar file in the c:\OraHome_1\jdk\jre\lib directory as the help file states to do. Bounced the server, but still no luck.
Is there a log file for connection issues to help point you to the potential cause?

Thank you for your quick response. I followed the instruction on Tim's blog and still no luck. Here is the URL and Driver Class I entered:
URL-
jdbc:sqlserver://our server name:1433;databaseName=northwind
Database driver class -
com.microsoft.jdbc.sqlserver.sqlServerDriver
My question:
1. Am I right to use one of databases as northwind or should use server name after "databaseName="
2. I used username "sa" that is sql server user. Is it correct?
3. Some articles mentioned "sqljdbc.jar" file. Does this mean files mssqlserver.jar, msbase.jar and msutil.jar?
Thank you for your help!
