Using MySQL connector from jar

I want to use MySQLconnector without unziping it. that is, directly from the jar file.
Anyone know how to do that??
thanx

MySQLconnector is the paquet with the necesary drivers to connect to a MySQL database server.
Those drivers are classes packed in a jar file.
To actually use the connector you have to load it with the following line:
Class.forName("com.mysql.jdbc.Driver") ;
That works fine if I unzip the jar file in the working directory. But if I just put the jar file alone, the line above throws an exception because it cannot be able to find the class.

Using mysql-connector-java-5.0.5 from oracle's java procedure.

I need to write the java procedure in Oracle, which will get connection to mySQL server and put some data into it. I am using official mysql-connector-java-5.0.5 driver for this job. Java class for this job work well outside the Oracle. The problem is:
When I try to import jar file of mysql connectior it fail son resolving inside the Oracle db. How can I get access to mysql from Oracle?

I've never tried to add a DB connection under this IDE installation earlier.
Just yeasterday I've created a project with some DB related (mySQL and Hibernate) libraries, although it compiled fine.

Include MySQL Connector in JAR

Is there a way to somehow include the MySQL connector in one of my JARs so that a user does not have to have two JARs in one folder for one program to run? Like, instead of having ThisJAR.jar AND MySQL_Connector.jar in one folder for ThisJAR to use MySQL_Connector for a database connection, I just want ThisJAR.jar.
I think I made that as confusing as it could possibly be. :-P
Thanks in advance,
Zach

A single link can take them to the 'download' page that uses [deployJava.js|http://java.sun.com/javase/6/docs/technotes/guides/jweb/deployment_advice.html] to check a suitable minimum version of Java is available before inserting the link to the launch/install file. If the user 'follows the prompts' from there, they might end up with a single menu item to launch the app., and no visible Jars.
I provide some [examples of the webstart API|http://pscode.org/jws/api.html] that show some services available to apps. launched using webstart, of particular use for your project might be the ExtensionInstallerService to install the DB, and the PersistenceService to store the path the user chose to install it (you would offer them the choice, of course).
Java webstart also offers other nice features like splash screens, icons..
Again, check the licensing arrangements - you might show the MySql license when installing.

"No suitable driver" error using Kodo 3.1.0, MySQL Connector/J & eclipse 3.0M8

Hi,
I'm getting the following error when trying to use the mapping tool from
within eclipse 3.0M8:
<error>-An error occurred running MappingTool
kodo.util.FatalDataStoreException: No suitable driver
NestedThrowables:
java.sql.SQLException: No suitable driver
<info>-Done.
I followed the instructions on using the eclipse plugin, including copying
all jars from kodo's lib folder to the plugin folder, copying the MySQL
Connector/J jar to the kodo plugin folder, adding all of those jars to the
project classpath, and even added an entry to the plugin.xml file to
include the MySQL Connector/J jar. If I remove the project reference to
the MySQL Connector/J jar, the error changes to:
<error>-An error occurred running MappingTool
kodo.util.FatalDataStoreException: com.mysql.jdbc.Driver
NestedThrowables:
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
<info>-Done.
This would imply that adding a <library> entry for the MySQL Connector/J
jar in my plugin.xml does not have any effect; if I remove it, I see the
same error as above. If I add the MySQL jar back to the project
classpath, the error changes back to 'No suitable driver' as above.
The behavior is the same whether I use the Kodo preferences
(Window\Preferences\Kodo Preferences) individually without a
kodo.properties file, or when I clear all individual properties and
indicate a kodo.properties file.
Help?
Thanks,
Matthew

I am not using Eclipse but am also experiencing problems similar to those
described below. The fact is I cannot validate a configuration file which
specifies either a traditional MySQL driver or a MySQL DataSoure.
I am using what I believe to be the official stable version of MySQL
Connector/J which is 3.0.11 and has been for several months. Are you
saying that 3.0.11 (or even 3.0.8) is not supported?
3.0.12 was recently released as the latest stable version so 3.0.11 should
at least be supported by now.

Everything looks correct to me. If you try an older version of the MySQL
driver (such as 3.0.8, which is what we test with), do you see anything
different?
If you try to run a stand-alone Kodo program using the MySQL driver, do
you see the same exception? If so, can you post the complete stack
trace?

Connecting mysql-4.1.12a-win32 with jakarta-tomcat-3.3.2 using mysql-connec

hi calverstine here, i have been trying to connect tomcat to mysql using mysql-connector-java-3.1.10, but does not have any clue how to do it, if you guys ask me to refer to :
http://dev.mysql.com/doc/connector/j/en/cj-classpath.html
it only told me about installing mysql to unix platform tomcat , not windows xp sp1, is there any tutorial tat's useful for using the mysql-connector-java-3.1.10? where should i place this folder after i unzipped it? what is CLASSPATH as being written in the previous URL that told us to set the environment variable?..anybody care to help?

You need to place the driver jar in a place that tomcat can access it; if that place is not already in the classpath for Tomcat, then you need to add it.
After that, you need to supply application code for Tomcat to contain that will use the driver and do whatever it is you want.
If you don't know how to do any of that, you need to either read the Tomcat documentation, or learn basic Java development.

PreparedStatements and MySQL Connector/J

Hi All,
I was wondering what is the exact SQL statement that is passed to MySQL server when we use PreparedStatements. I was trying using MySQL Connector/J, type4 driver. I tried with a simple servlet
    public void doGet(HttpServletRequest request, HttpServletResponse response)
    throws IOException, ServletException   {
        response.setContentType("text/html");
        PrintWriter out = response.getWriter();
        out.println("<html>");
        out.println("<body>");
        out.println("<head>");
          try {
               Class.forName("com.mysql.jdbc.Driver");
               Connection con=DriverManager.getConnection("jdbc:mysql://localhost/mydb?user=root","root","");
               //Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
               //Connection con=DriverManager.getConnection("jdbc:odbc:test");
               PreparedStatement pst=con.prepareStatement("select * from AS_ITM where ID_ITM=?");
               out.println("PreparedStatement = "+pst);
               out.println("<br>");
               pst.setString(1, "10");
               out.println("PreparedStatement = "+pst);
               //ResultSet rs=pst.executeQuery();
               con.close();
          }catch(Exception e){
               out.println(e);
        out.println("</head>");
        out.println("<body>");
        out.println("</body>");
        out.println("</html>");
Here I am printing PreparedStatement object's generated SQL twice and not even executing the query.
And the result is:
PreparedStatement = com.mysql.jdbc.PreparedStatement@19f3736: select * from AS_ITM where ID_ITM=** NOT SPECIFIED **
PreparedStatement = com.mysql.jdbc.PreparedStatement@19f3736: select * from AS_ITM where ID_ITM='10'
See second statement? I have not even sent it to the server.
So is this jdbc driver preparing a simple Statement before it is sent to MySQL server?
Is it what a jdbc driver is supposed to do? So then whats the use of PreparedStatement?Thanks,
Kishor

Hi,
Just exactly what a JDBC driver is supposed to do with a PreparedStatement is not specified in JDBC I believe. I think they only requirement is that a PreparedStatement should be able to insert the various data types correctly into an SQL string.
I am fully aware that PreparedStatements should also be able to give a better performance, for instance by only sending the parameters when you use it the second time, and not the whole the SQL. But I think this is up to the database and driver implementation to decide whether to do this, and how.
Remember, the JDBC driver may be sending other information across to the database than the SQL. We can't see that from looking at the PreparedStatement only. You would have to use a network packet sniffer to see all data exchanged between the driver and the database

[solved] MySQL Connector C++ 1.0.5

Hello everyone,
I'm trying to connect to a MySQL db via C++. MySQL has the connector and API available for this. In the process of building this I've run into some troubles/questions.
First off is that MySQL states that MySQL Workbench uses this connector:

Thanks wonder for your reply.
How do I move files using PKGBUILD? I've found an install -D command but that looks at best at copying the file:
install -D COPYING $pkgdir/usr/share/licenses/$pkgname/COPYING
Another question is that the patch that is executed is only for gcc-4.4 is there a way to have an if statement for that?
no. we don't have any other version in our repo and that patch will work also with older gcc
Edit: a simple solution is to copy them using install -D and then remove them... is this the correct sollution?
yes. and remove the others two files as well.

Hi Kelvin,
I am able to connect through LDAP browser.
I am able to do provisioning also.
I followed the following steps to do recon
1. i imported iPlanetXLResourceObject.xml using Depolyment manager.
2.In Task scheduler, stop execution and disable check boxes are not checked ,XLDeleteUsersAllowed is set to true, user container is set to one of the LDAP branch,
Trusted source to true, rest of the values are default values.
3.In ITResorce, in the Recon Attribute Lookup Code is set to AttrName.Recon.Map
I scheduled a recon task and deleted a user in LDAP.
I am getting the above said error,should i set any other values other than these.
Kindly suggest me the approach,
Thanks,
divya

How to include the mysql-connector in a simple .jar file

Well I started up with java again. Just messing around. This project I'm making now is just plain simple, I have a program thats going to read a table in a database from a server I have here at home. It works fine if I do like this: java javafil to run the file, it reads from the database fine.
But when I made a .jar file out of it using this command: jar cmf manifest.txt javafile.jar *.class
It won't connect to the database. Or it doesn't print out the rows in the table. So I thought I have to include the mysql-connector with the .jar.
manifest.txt
Main-Class: javafile
Now what is an easy way to do this?
This program is also going to be run from a computer that might not have the mysql-connector installed on the computer. Like a friend of mine wants to connect to the database and read it.
I've tried to google "mysql connector in a .jar file" but I get tons of informations about the mysql-connector.jar instead of what I'm looking for.
Thanks,
Torbj�rn Svae

Yeah but the other computer might not have that connector file on their computer. So is there like I way I can use it when it is in the .jar file? Thats kinda what I wanted. You cannot include another JAR in a JAR file. You however can extract it and put the classes in your JAR. Verify the license agreement if it is allowed. Although this is considered as a bad practice (poor upgradebility and maintainability).
If you don't want to use the -cp parameter, then use the class-path entry of the manifest.mf of your JAR. You can also write a batch file with the whole JAR -cp command in a single line and run the batch file instead.
Pluss, even though I have the right classpath in the environment variables set, it doesn't work for me either. So I guess it doesn't load the connector when running the .jar file.The classpath environment variable has nothing to do with running JAR's. Forget about it and use the -cp or -classpath parameter.

Java\jdk1.6.0_02\jre\lib\ext\mysql-connector-java-5.1.16-bin.jar was unexp

Hello, please i am new to Jdeveloper and weblogic servers and i developed an application using jdeveloper and when i try to run the application it brings up this error message
"*** Using HTTP port 7101 ***

I tried deleting the jdk1.6.6.0_02 and tried it again but it still did not run, I also uninstalled the JDeveloper and weblogic server and reinstalled them but the error message still pops up. Please i need help to fix this.
Thanks.

Andrew,
Thanks for the lightning response... but the problem has been solved.
I rebooted again, and installed again (didn't download again because the filesize checked out) and now it works fine, and I'm none the wiser as to the root cause of the problem, except that rt.jar has magically appeared:

I presume that the installer failed on rt.jar, probably because something (something in my start-up, I suppose) was using the JRE while the instal was running... but I didn't do anything different the second time (to the best of my knowledge).

Error in extracting data from SAP using mySQL server database

Hello Experts.
We are now using MySQL server 2005 database for Nakisa OrgChart. We have already configured the SAPExtractor settings.

We are getting the error upon starting the extraction

Hello Luke,
We have not done any modification of the downloadschema file. We receive message: The XML page cannot be displayed

The SAP account we used has SAP_AlLL, SAP_NEW authorizations. Are these authorizations sufficient to perform the data extraction?

JDBC MySQL Connector/J problems when using in applets

I wrote a piece of code which uses the MySQL Connector/J which worked in a normal shell application but when used in an applet it just didnt print anything. The code is:
import java.net.*;
import java.sql.*;
class DB {
static Connection c;
static Statement stmt;
static ResultSet to;
public static String[] getUsers() {
     String str[] = new String[100];
     try {
          Class.forName("com.mysql.jdbc.Driver").newInstance();
     catch (Exception E) {}
     try {
          c = DriverManager.getConnection("jdbc:mysql://localhost/PROGRAM?user=blah&password=blah");
          stmt = c.createStatement();
          to = stmt.executeQuery("SELECT usr_user FROM usr");
          for(int i=0; to.next(); i++) str[i] = to.getString(1);
     catch (SQLException E) {}
     return str;
Is there a problem accessing a MySQL Database via an applet

Applet runs out of a sandbox, if you print the exception, you'll see that you have run into security access violation:
catch (SQLException E) {
E.printStackTrace();
}This will tell you why your applet didn't print anything. Just a firendly advice, never try to catch something and don't display what was caught.
;o)
V.V.
PS: To solve, your problem, you can either sign the applet or use a policy file to grant the applet the required access right.

Fat Jar Export: Could not find class-path entry for 'C:Java/jdk/mysql-connector-java-

what's the problem?
ok, i am using a mysql db und using the driver mysql-connector-java-5.1.8-bin.jar....
i improted this jar file like this run -> run configuration -> classpath -> add external jar....
pls help me

That looks like it might be a binary-distribution JAR that you should unjar. The actual JAR for the classpath is probably inside it.

Unable to extract connector/j jar file(mysql)

im have having a problem on extracting mysql's connector/j jar file on j2sdk1.4.0.
and may i know does sun allows windows xp users to install various kind of versions of j2sdk? for example, install j2sdk1.4.0 into c:\j2sdk1.4.0, and j2sdk1.4.2_05 into c:\j2sdk1.4.2_05?
what to do using j2sdk1.4.0 for connector/j?
i would like to know manual steps instead if automatic step provided by netbean.
i wish this problem could be solved as sonn as possible

im have having a problem on extracting mysql's
connector/j jar file on j2sdk1.4.0.I'm not sure what this means. The MySQL connector JAR isn't part of any JDK. You've got to download it and put it in your CLASSPATH.
