Posted on 2002-06-04

I tried serveral ways to make it work; however
I can't.

Actually, my problem is i don't know where
i have to set for CLASSPATH.

I also tried for the second way, putting jar file
into jre/lib/ext, but i think it might have
some change in 'String driverName = "org.gjt.mm.mysql.Driver"' but i don't know what it
have to be !!!!

code to access the driver:
Class.forName("org.gjt.mm.mysql.Driver");

Connection conn = DriverManager.getConnection("jdbc:mysql://SERVER1:3306/DB", "UN", "PW");

to set the classpath in windows:
C:\> set CLASSPATH=\path\to\mm.mysql.jdbc-[version];%CLASSPATH%
to set the classpath in unix:
$setenv CLASSPATH /path/to/mm.mysql.jdbc-[version]:$CLASSPATH

HTH,

Well...i think i found the problem...
I went to DOS mode to set the CLASSPATH.
then i exit which means - I thought - the CLASSPATH
is also deleted...

So what i have to do ???

yes.. you would have to set the classpath for each dos window.

Or you can set it as an environment variable:
In WinNT/Win2k:
In Win9x:

I put the unjar all files at c:\mm.mysql,
then i set the CLASSPATH=c:\mm.mysql.

And
String driverName = "org.gjt.mm.mysql.Driver";
Class.forName(driverName);

it still doesn't work... what i did wrong ????

Here is a silly question, but have to make sure, did you un-jar the jar file that you downloaded?  Make sure that you have extracted the proper jar from within the original jar, then you could place it into the lib/ext directory.  I've done that on a W98 and W2000 machine without any problems, never needed to set the path.  Ok, I see that you did un-jar the files, then copy the bin jar named: mm.mysql-2.0.14-bin.jar and place it into the lib/ext directory.
