Connetion between Tomcat & MySQL
Hi, I am using Tomcat 3.3.1 and MySQL 4.0 in Window XP. MySQL engine is running. When I run my jsp, it stated the error that "import com.mysql.Driver" not found. Anyone know how to install the driver properly? I read something about setting the class path. But where to set? I don't know much about the MSDOS command and specify the envirnomental variables in Window XP. I download both the J/Connector & OCBC driver from MySQL. Where should be the exact location to store?

Re: Connetion between Tomcat & MySQL
Assuming that you aren't using JDBCRealm, then it should be enough to put the jar file in $TOMCAT_HOME/lib/apps. If you are using JDBCRealm, then place it in $TOMCAT_HOME/lib/common. Setting the CLASSPATH is evil ;-). "Amy Cheung" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > Hi, > > I am using Tomcat 3.3.1 and MySQL 4.0 in Window XP. > MySQL engine is running.

Re: Connetion between Tomcat & MySQL
I'll assume that you're using Connector /J. Stick the file mysql-connector-java-x.y.zz-bin.jar (where "x.y.zz" is the version number) in Tomcat's common/lib directory. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Connetion between Tomcat & MySQL
My apologies (and my tping error), the directory should be "common/lib", not "lib/common". - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Connetion between Tomcat & MySQL
Any JDBC driver for mysql (that works for you) will do.

Re: Connetion between Tomcat & MySQL
There is two things you can do. Set your CLASSPATH to include mm.mysql.driver and include the jar in your webapps lib folder. HTH Kind Regards Schalk Volume4
Re: Connetion between Tomcat & MySQL
OK. Thanks. It can connects to the database now.
Here is a minor problem. The results I obtained from
the query is a ResultSet, rs. I keyed in this code:
while (rs.next())
{
System.out.print(rs.getString("RoomID");
}
In the Tomcat server, it printed the results that I
wanted. How to incorporate that results into the html
code to show on the web page? I tried but it's give me
error that cannot convert ResultSet into String.
Thanks,

RE: Connetion between Tomcat & MySQL
That's just not good advice at all. I don't know where people get the idea of touching CLASSPATH when they're talking about Tomcat and web-apps in general. Drivers should be placed in common/lib or WEB-INF/lib. That's IT. And mm.mysql.driver? You mean: com.mysql.jdbc.Driver And one last rant, as Chris Williams started to point out... ODBC is a Microsoft data access abstraction layer. ODBC = Microsoft Way of doing it JDBC = Java way of doing it So you'd only download or use the ODBC driver if you were accessing MySql from a VB or C# program. > -Original Message- > From: Schalk [mailto:[EMAIL PROTECTED] > Sent: Tuesday, September 09, 2003 6:20 AM > To: Tomcat Users List > Subject: Re: Connetion between Tomcat & MySQL > > > There is two things you can do.

Re: Connetion between Tomcat & MySQL
You may want to put the JDBC driver jar file under %TOMCAT_HOME%/common/lib and try again. This is the location where the classloader loads the classes which makes available to all Tomcat applications.
