This section discusses how to obtain MySQL Cluster Connector for Java sources, binaries, compiling, installing, getting started.
Obtaining MySQL Cluster Connector for Java. You can obtain the most recent NDB Cluster release incorporating MySQL Cluster Connector for Java from downloads.mysql.com.
Building and installing MySQL Cluster Connector for Java from source.
You can build and install ClusterJ, ClusterJPA, or both as part
of building and installing NDB Cluster, which always requires
you to configure the build using a
--with-plugins option that causes
NDB support to be included, such as
--with-plugins=max. Other relevant plugin names
that can be used with this option include the following:
clusterj: Required for building NDB Cluster with ClusterJ support.
openjpa: Required for building NDB Cluster with ClusterJPA support.
In addition, you should use the following two configure options when configuring a build to include ClusterJ, ClusterJPA, or both:
--with-classpath=: Required for building NDB Cluster with ClusterJPA support.
pathmust include the path or paths to the OpenJPA libraries and OpenJPA dependencies on your system.
--with-extra-charsets: ClusterJ uses the
ucs2character set for internal storage, and ClusterJ cannot be built without it. The simplest way to ensure that this character set is available is to configure using
--with-extra-charsets=all. This is what we recommend that you use, unless you have some reason for not wanting to include all character sets, in which case you should make sure that
ucs2is specified in the character set list passed to this option.
A typical configuration step in building NDB Cluster with support for both ClusterJ and ClusterJPA might look like this:
./configure --with-plugins=ndbcluster,clusterj,openjpa \ --with-extra-charsets=all \ --with-classpath=
path/to/openjpa/libs must include the
driver-5.1.10.jar(This is the MySQL JDBC driver)
Not all available options for configuring an NDB Cluster build are shown in this section. For information about other options that can be used, see Installing MySQL Using a Development Source Tree, or consult the output of configure --help.
After configuring the build, run
make install as you normally
would to compile and install the NDB Cluster software. Following
installation, the MySQL Cluster Connector for Java jar files can be found in
share/mysql/java under the MySQL installation
directory (by default, this is
You can also use the included file
storage/ndb/clusterj/pom.xml for building
ClusterJ with Maven.
Setting up your build environment to use Maven requires that you
run mvn install in the
clusterj directory. Assuming that you are
already in the root directory of the NDB Cluster source tree, you
can accomplish this by performing in your shell the steps shown
cd storage/ndb/clusterj mvn install
This causes ClusterJ—including the
clusterj-jpa plugin—to be built, with the
.jar files installed in the local
MySQL Cluster Connector for Java jar files.
After building and installing NDB Cluster with MySQL Cluster Connector for Java, you
should find the following JAR files that are needed for using
ClusterJ and ClusterJPA in
share/mysql/java/ under the NDB Cluster
clusterj-api.jar: This is the compile-time jar file, required for compiling ClusterJ application code.
clusterj.jar: This is the runtime library required for executing ClusterJ applications.
clusterjpa.jar: This is the runtime library required for executing ClusterJPA applications. This jar file must be in your classpath when running OpenJPA with ClusterJPA.
