Loading MySQL to Borland's Java

Question

I still can't connect to MySQL.
I looked in the other threads' instructions, I think I am doing everything correctly.
I still get the
java.lang.ClassNotFoundException:org.gjt.mm.mysql.Driver
exception on the
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
command.
This is my system:
Java: Borland's JBuilder home edition.
Operating System: Windows XP
Driver I am trying to use: GNU's mm.mysql-2.0.14
Relevant Directories:
MySQL: C:\MySQL
GNU's driver: C:\MySQL\mm.MySQL-2.0.14 (I thought it
made sense to put it here.)
Relevant Environment Variables:
CLASSPATH:.;C:\MySQL\mm.MySQL-2.0.14\mm.mysql-2.0.14- bin.jar
I have also tried:
CLASSPATH:.;C:\MySQL\mm.MySQL-2.0.14\lib\jdbc2_0-stdext.jar
CLASSPATH:.;C:\MySQL\mm.MySQL-2.0.14]\lib\jta-spec1_0_1.jar
-and-
CLASSPATH:.;C:\MySQL\mm.MySQL-2.0.14]\org
I didn't set the environment variables
path to C:\j2sdk1.4.0_01
j2ee_home to c:\j2sdkee1.3.1
java_home to c:\j2sdk1.4.0_01
because I don't have any files on my computer that start
with j2sdk. Apparently, JBuilder uses other files.
I can use MySQL with the command line mysql command, but only from the c:\mysql\bin directory.

Answer 1

I can't tell for sure from the information you give, but I think you're mixing apples and oranges. Here's an excerpt from the readme file that comes with the driver:
MM.MySQL is distributed as a .jar archive containing the sources
and class files as well as a class-file only "binary" .jar archive
named "mysql-2.0.13-bin.jar".
You will need to use the "jar" command-line utility that comes with your JDK
to un-archive the distribution.
Once you have un-archived the distribution .jar archive,
you can install the driver in one of two ways:
Either copy the org subdirectory and all of it's contents
to anywhere you like, and put the directory holding the org subdirectory
in your classpath, or...
Put mysql-2.0.13-bin.jar in your classpath, either by adding the
FULL path to it to your CLASSPATH enviornment variable, or putting it
in $JAVA_HOME/jre/lib/ext.
I placed mysql-2.0.13-bin.jar in $JAVA_HOME/jre/lib/ext and it works fine.
If you copied the org subsubdirectory and all of it's contents to C:\MySQL\mm.MySQL-2.0.14, then use that as your classpath.
If you're trying to use just the jar file, then the classpath entry should be the directory that contains the jar.
Because you don't have C:\mysql\bin in your PATH, you either have to be in that directory or prepend your sql commands with C:\mysql\bin for the commands to be recognized.
