Re: Using servlet and mysql
Dear All,
I already put mysql database driver (jar file) in directory
catalina_home\common\lib and changed 8080 to 3306 but I got the error
java.sql.SQLException: Unable to connect to any hosts due to exception:
java.net.ConnectException: Connection refused: connect. What should be the
matter? I put the database name, teh in directory catalina_home\webapps\ROOT\.
Is this correct? In which directory should I actually put the database name?
Please help. I'm running out of time! Thank you so much.
Yours Sincerely,
TEH

Hi,
You'll need to get the MySQL database driver and put them in the
{catalina_home}\common\lib folder. The driver can be easily obtained
through MySQL site.
BTW, as far as i know, the default port for MySQL database is 3306, so
you might wanna change that. 8080 is for Tomcat, not the database.
Seems like not many new users of connection pooling went through
Apache's documents. Please don't waste their effort, take a look at it
before you start to attempt anything.

Yes, the login name and password are correct. I created the database name, teh,

Re: Using servlet and mysql
Hi,
This is getting more confusing, you mentioned earlier that you're using
MySQL but now it is a Microsoft Works Database. Hmmm perhaps i'm missing
something?
Anyway, if the database you're using is something like an Access
database, you'll just need to use the correct driver and point the URL
to your database file. Can't help you here coz i never tried that before
(Access is like from another world to me). Perhaps you should try other
mailing list, and not Tomcat's.

Re: Using servlet and mysql
Hi,
In short, to get a MySQL server up, try the following:
1) Install an instance of MySQL
2) Install the client software (you can get them from the MySQL web site
too, like MySQL Administrator etc or you can try the MySQL Front for
older version of MySQL)
3) Create a database using the client software.
4) Put the MySQL drivers in the common\lib folder(if you want it to be
global) or in your WEB-INF\lib folder (if you want it to be local)
5) Run the Tomcat, try your code
Not sure whether this is good enough, perhaps someone with better
explanation skill can explain it better than me.
Remember google is always your best friend. :)

Re: Using servlet and mysql
Access databases can only be accessed by ODBC (default present at
2000 / XP). MySQL has nothing to do with it.
1) First create your Access database (.mdb, I don't know what a
Works database is?). It may be placed anywhere on your Tomcat Server.
2) Then configure it for usage by ODBC. Click Start - Run:
%SystemRoot%\system32\odbcad32.exe
In the tab System-DSN make a new entry (I hope I translate well from
Dutch here).
2a) Give the entry a free-choosable unique name, for instance 'MyDatabase'
2b) Specify the path to the database you created in step 1)
3) Attach to the driver using:
// Load the driver, at some Virtual Machines
// newInstance() appears to be necessary
Class.forName( sun.jdbc.odbc.JdbcOdbcDriver ).newInstance();
4) Connect to the database using:
Connection newConnection = DriverManager.getConnection(
jdbc:odbc:MyDatabase );
Note: Microsoft - as usual - implemented some differences in SQL-syntax!

directory to
put the database. However, in the program there was a statement
.(insert into login_table values(?,?)); I do not understand the
usage of login_table. Does it mean that I should create login_table
in database teh? Really need to get this working to
day. Please help. Thank you.

Hi,
Is your login name and password correct? It shows 'root' and the
password is 'root' in the code you posted there.

Dear All,
I already put mysql database driver (jar file) in directory
catalina_home\common\lib and changed 8080 to 3306 but I got the
error java.sql.SQLException: Unable to connect to any hosts due
to exception: java.net.ConnectException: Connection refused:
connect. What should be the matter? I put the database name, teh in
directory catalina_home\webapps\ROOT\. Is this correct? In which
directory should I actually put the database name? Please help. I'm
running out of time! Thank you so much.

Hi,
You'll need to get the MySQL database driver and put them in the
{catalina_home}\common\lib folder. The driver can be easily
obtained through MySQL site.
BTW, as far as i know, the default port for MySQL database is
3306, so you might wanna change that. 8080 is for Tomcat, not the database.
Seems like not many new users of connection pooling went through
Apache's documents. Please don't waste their effort, take a look
at it before you start to attempt anything.

Re: Using servlet and mysql
I would actually recommend steering clear of the jdbc-odbc bridge driver. It's not stable enough for production use on any level.

Re: Using servlet and mysql
I agree completely. For testing purposes or migration it works. We are switching to MySQL asap, but dozens of customers are still using it...
