This section provides basic information for writing, compiling, and executing applications that use ClusterJ. For the API documentation for ClusterJ, see Section 4.3, “ClusterJ API Reference”.

Requirements.  ClusterJ requires Java 1.5 or 1.6. MySQL Cluster must be compiled with ClusterJ support; MySQL Cluster binaries supplied by Oracle include ClusterJ support beginning with MySQL Cluster NDB 7.1.1. If you are building MySQL Cluster from source, see Building and installing MySQL Cluster Connector for Java from source, for information on configuring the build to enable ClusterJ support.

Beginning with MySQL Cluster NDB 7.1.2, to compile applications that use ClusterJ, you need the clusterj-api jar file in your classpath. To run applications that use ClusterJ, you need the clusterj runtime jar file; in addition, libndbclient must be in the directory specified by java.library.path. Section, “Executing ClusterJ Applications and Sessions”, provides more information about these requirements.


The requirements for running ClusterJ applications were somewhat different in MySQL Cluster NDB 7.1.1; see Building and executing ClusterJ applications in MySQL Cluster NDB 7.1.1, if you are using this release.
