If you want to create a custom Connector/MXJ package that includes a specific mysqld version or platform then you must extract and rebuild the connector-mxj.jar (Connector/MXJ v5.0.3 or earlier) or connector-mxj-db-files.jar (Connector/MXJ v5.0.4 or later) file.

First, you should create a new directory into which you can extract the current connector-mxj.jar:

shell> mkdir custom-mxj
shell> cd custom-mxj
shell> jar -xf connector-mxj.jar
shell> ls
5-0-22/
ConnectorMXJObjectTestExample.class
ConnectorMXJUrlTestExample.class
META-INF/
TestDb.class
com/
kill.exe

If you are using Connector/MXJ v5.0.4 or later, you should unpack the connector-mxj-db-files.jar:

shell> mkdir custom-mxj
shell> cd custom-mxj
shell> jar -xf connector-mxj-db-files.jar
shell> ls
5-0-27/                         
META-INF/                       
connector-mxj.properties

The MySQL version directory, 5-0-22 or 5-0-27 in the preceding examples, contains all of the files used to create an instance of MySQL when Connector/MXJ is executed. All of the files in this directory are required for each version of MySQL that you want to embed. Note as well the format of the version number, which uses hyphens instead of periods to separate the version number components.

Within the version specific directory are the platform specific directories, and archives of the data and share directory required by MySQL for the various platforms. For example, here is the listing for the default Connector/MXJ package:

shell>> ls
Linux-i386/
META-INF/
Mac_OS_X-ppc/
SunOS-sparc/
Win-x86/
com/
data_dir.jar
share_dir.jar
win_share_dir.jar

Platform specific directories are listed by their OS and platform - for example the mysqld for Mac OS X PowerPC is located within the Mac_OS_X-ppc directory. You can delete directories from this location that you do not require, and add new directories for additional platforms that you want to support.

To add a platform specific mysqld, create a new directory with the corresponding name for your operating system/platform. For example, you could add a directory for Mac OS X/Intel using the directory Mac_OS_X-i386.

On Unix systems, you can determine the platform using uname:

shell> uname -p
i386

Now you need to download or compile mysqld for the MySQL version and platform you want to include in your custom connector-mxj.jar package into the new directory.

Create a file called version.txt in the OS/platform directory you have just created that contains the version string/path of the mysqld binary. For example:

mysql-5.0.22-osx10.3-i386/bin/mysqld

You can now recreate the connector-mxj.jar file with the added mysqld:

shell> cd custom-mxj
shell> jar -cf ../connector-mxj.jar *

For Connector/MXJ v5.0.4 and later, you should repackage to the connector-mxj-db-files.jar:

shell> cd custom-mxj
shell> jar -cf ../connector-mxj-db-files.jar *

You should test this package using the steps outlined in Section 25.5.2.3, “Connector/MXJ Quick Start Guide”.
