MYSQL :: Problem With MySql And Java Under Windows

MySQL + Java
Basically i want a GUI frontend to connect to a database. My experience of this has been visual basic app and access database. The only thing i liked was that to deploy the user only needed the app and the database, deployment was simply packaging the 2 together.Can i make a database using mySQL and deploy it as in the example above? Or does the user need to have a mySQL installed ? Now i all read about databases mySQL/oracle is of a server running the database and the app connecting. However for my app the information will not be updated or changed and therefore i don't need to connect to a server to access the database?

Mysql Connector Java JAR
I am making a Java Applet connects to mysql database, it works well in
application mode. When I run it in applet mode, obviously the client
running the applet should have the mysql connector file
(mysql-connector-java-3.0.8-stable-bin.jar).

So the question is how to bundle this mysql jar file with my applet jar
file. I've tried to make both 2 files together in the html file:

archive="PCMApplet.jar;mysql-connector-java-3.0.8-stable-bin.jar"

the GUI shows up but the connection call to database is failed:
java.lang.ClassNotFoundException: org.gjt.mm.mysql.Driver
It seems to me that the mysql-blah.jar is not being used.

Transactions With Java And MySQL
I'm trying to port the use of postgresql db to mysql. I'm using
Java and having the following problem - I can't seem to write more
than 1 query per execution. Easier to explain with an example that
worked under postgresql and does not using mysql:

aStatement.executeQuery("BEGIN; DELETE FROM table1; DELETE FROM
table1; DELETE FROM table3; COMMIT;");

If I separate this into 5 different queries it works fine. Any
ideas?

Communicating With MySQL Through Java
In java is it possible for me to open a socket with a MySQL database and directly send infomation or would I need to use something like php as a buffer.

I know this isn't secure, but the application I am writing does not neet security. I'm just looking for some method to add information to a database. I made a simple .jar file mhich can do what I am looking for but I now I need something which I can upload to a remote webserver.

Deleting Mysql Entries In Java
I am asking the user to put in a number and the java prog will look for the corresponding entry and delete it.

so far i have asked the user and stored their choice and now move onto the part of deleting the entry.

i need to call the method for deleting and pass the parameter of the userÂ´s entered number to it.

if im taking the right approach or if "DAO" patterns would be more useful?

Java Mysql Show Table Status
I am using java to retrieve a resultset with "show table status" mysql

In the metadata object it is showing as VARCHAR but when I do
getString() it is returning me the object string (e.g. "[B@1e3e7d2")and
not the actual database value. I am using Mysql 4.1 and jdbc driver
3.1. I tried getB/Clob, getBytes, getCharacterStream() and none of

Java In Linux (Redhat 9) To Access MySQL
Using a Java program, I can connect to the test database in MySQL. The
test database is installed using a MySQL utility, and it can be accessed
by any user without supplying a password. The relevant lines in my Java
(Java version 1.4.1) code are:

Connection con = null;
String url = "jdbc:mysql:///test"; // <== no user or password specified
con = DriverManager.getConnection(url);

However, when I try to connect to the accounting database (built as one
follows the Larry Ullman's "MySQL" book), the program fails. I need to
supply a user and a password. The relevant lines are now:

Connection con = null;
String url = "jdbc:mysql:///accounting?user=root&password=pswd"; // <==
con = DriverManager.getConnection(url);

I cannot get a connection. The error message is:

"Invalid authorization specification: Access denied for user:
'root@thorvald' (Using password: YES)"

(thorvald is my machine name.)

I have tried all sorts of variations on the url, trying to access the
accounting database, with no success. I can use the same user/password
of root/pswd within the mysql monitor to access anything I want.

Any ideas?

Again, I am using Linux (Redhat 9) , Java 1.4.1, MySQL 4.0.13, and the
MySQL ConnectorJ 3.0.8 (for Java access to MySQL).

Connecting To A Remote Mysql Server From A Java Application On Another Machine

But, now how do i set the connection string so that the java application accesses the DB (/server) from my local PC?

Windows 2003 To Windows XP Pro Secure Communications...
I have a Windows 2003 Server running a Coldfusion app that needs to constantly update a MySQL database on a Windows XP Pro machine.

These machines are not on a LAN and are physically separate. I'm trying to find a way to establish secure communications between them since I do not want port 3306 open to the entire internet.

What I've Tried
So far I tried CopSSH with Putty but this did not work because I need to manually initiate all sessions and enter passwords by hand.

Since there aren't any SSH solutions that allow persistent, automatic connections, it appears I need to go with VPN.

The VPN Dilemma
I tried creating a VPN server on the WinXP MySQL machine but I cannot get ODBC to work remotely. How do you get the ODBC on the local (Win 2003) machine to recognize the MySQL database on the remote (WinXP Pro) server?

Note: I also understand that getting SSL working on Windows is a pain in the butt. I'm trying to steer completely clear of that. I don't have the tools to recompile, etc.

Java.sql.SQLException
Currently im trying to use java and mySQL together using JDBC.
But i've encountered an error message when i execute my codes.

before this error message, they printed this:

"Tue 13 Sep 12:55:31 SGT 2005 TRACE:"

i guess it has got to do with this part of my code:
conn = DriverManager.getConnection("jdbc:mysql://localhost/foaf", "", "abcde");

Connecting To Database Using Java
i am able to connect to mysql database located at localhost:3306 inside tomcat. But i wanna do it in stand alone command line java program.

this is what my code looks like:

com.mysql.jdbc.jdbc2.optional.MysqlDataSource d = new com.mysql.jdbc.jdbc2.optional.MysqlDataSource();

Properties prop = new Properties();
prop.put(Context.INITIAL_CONTEXT_FACTORY, provider);
ctx = new InitialContext(prop);

ctx.bind("jdbc:mysql://localhost:3306/bsidb", d);

// where provider is a string equal to "com.sun.jndi.fscontext.RefFSContextFactory"
// and bsidb is my database name

when i do the look-up it successfully returns the datasource.
and when i do getconnection
it returns a connection to the datasource.

the problem is when i do query... it returns an SQLException: No database selected

i am not using any config files because as i've said, i will do the connection using stand alone java program.
i use mysql4.1 and mysql-connector-java-3.0.16-ga-bin.jar, fscontext.jar are in my classpath.

[java] Jdbc, More Than One Sql Command

Does anybody know why I cannot execute something like that in my Java
program:

stat.execute("CREATE TABELE a(b int);INSERT INTO a(b) VALUES(1);");
???

something like this works fine:
stat.execute("CREATE TABELE a(b int);");
stat.execute("INSERT INTO a(b) VALUES(1);");

i was trying to change the string:
"CREATE TABELE a(b int);
INSERT INTO a(b) VALUES(1);"
"CREATE TABELE a(b int); INSERT INTO a(b) VALUES(1);"
and nothing works.

Can anyone tell me why this jdbc driver cannot take this??? If I put the
string:
"CREATE TABELE a(b int);INSERT INTO a(b) VALUES(1);"
into mysql console everthing works fine....

I don't get it. I was trying to run it in pg, and evertyhing worked fine.

Can I Use MySQL With A Mac And Windows
I need to share a MySQL database with a guy that uses a Mac, but I don't know anything about the Mac environment. I use WinXP. He has a server that has MySQL loaded on it. I want to create the database, then both of us want to be able to access it or make changes to it via the web.

What type of products do I need? I figure a good MySQL reference book is a necessity. Is there some type of front end application that he can run. I think I can run Access as a front end once it is set up properly. Am I making sense?
