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
mysql-connector-mxj.jar
(Connector/MXJ
v5.0.3 or earlier) or
mysql-connector-mxj-gpl-[ver]-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 5-0-51a/ META-INF/ connector-mxj.properties
The MySQL version directory, 5-0-22
or
5-0-51a
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
In Connector/MXJ v5.0.9 and later, an additional
platform-map.properties
file is used to
associate a specific platform and operating system combination
with the directory in which the mysqld
for
that combination is located. The determined operating system and
platform are on the left, and the directory name where the
appropriate mysqld is located is on the right. You can see a
sample of the file below:
Linux-i386=Linux-i386 Linux-x86=Linux-i386 Linux-i686=Linux-i386 Linux-x86_64=Linux-i386 Linux-ia64=Linux-i386 #Linux-ppc=Linux-ppc #Linux-ppc64=Linux-ppc Mac_OS_X-i386=Mac_OS_X-i386 Mac_OS_X-ppc=Mac_OS_X-ppc Rhapsody-PowerPC=Mac_OS_X-ppc #Mac_OS-PowerPC= #macos-PowerPC= #MacOS-PowerPC= SunOS-sparc=SunOS-sparc Solaris-sparc=SunOS-sparc SunOS-x86=SunOS-x86 Solaris-x86=SunOS-x86 FreeBSD-x86=FreeBSD-x86 Windows_Vista-x86=Win-x86 Windows_2003-x86=Win-x86 Windows_XP-x86=Win-x86 Windows_2000-x86=Win-x86 Windows_NT-x86=Win-x86 Windows_NT_(unknown)-x86=Win-x86
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 ../mysql-connector-mxj-gpl-[ver]-db-files.jar *
You should test this package using the steps outlined in Section 22.4.3.3, “Connector/MXJ Quick Start Guide”.
Because the
mysql-connector-mxj-gpl-[ver]-db-files.jar
file is separate from the main Connector/MXJ classes you can
distribute different
mysql-connector-mxj-gpl-[ver]-db-files.jar
files to different hosts or for different projects without
having to create a completely new main
mysql-connector-mxj-gpl-[ver].jar
file
for each one.
