Other wrappers are to be used only with the matching JDBC drivers that must be available when compiling them. Therefore there is no need to worry about its path.Ĭompiling the ApacheInterface wrapper requires that the Apache common-DBCP2 package be installed. Recent versions also add a JavaWrappers.jar that contains all these wrappers. Binary distributions have this wrapper already compiled as a JdbcInterface.jar file installed in the plugin directory whose path is automatically included in the class path of the JVM. The JdbcInterface wrapper is always usable when Java is present on your machine. However, this is not mandatory for CONNECT which adds the package name if it is missing. Note: Conforming java naming usage, class names are preceded by the java package name with a slash separator. The wrapper to use for a table can also be specified in the option list as a wrapper option of the “create table” statements. The wrapper used by default is specified by the connect_java_wrapper session variable and is initially set to wrappers/JdbcInterface. Makes connection to a Postgresql data source. Makes connection to an Oracle data source.
Must be used with a MySQL driver that implements data sources. Makes connection to a MariaDB data source. Used to make the connection with available drivers the standard way.īased on the Apache common-dbcp2 package this interface enables making connections to DBCP data sources with any JDBC drivers. However, they must be compiled and installed manually. Other wrappers, only available with source distribution, enable connection to a Data Source, eventually implementing pooling. It uses the standard way to get a connection to the drivers via the DriverManager.getConnection method. The default wrapper, JdbcInterface, is the only one distributed with binary distribution. In the source distribution, they are located in the CONNECT source directory. They are the source of the java wrapper classes used to access JDBC drivers. For instance on Ubuntu I was obliged to enter: export JAVA_HOME=/usr/lib/jvm/java-8-oracleĪfter that, the compilation of the CONNECT JDBC type was completed successfully.
When this happen, provide a Java prefix as a hint on where the package was loaded. Java_JAVAH_EXECUTABLE Java_JAVADOC_EXECUTABLE) For instance on Linux the Oracle Java JDK package might be installed in a path not known by the CMake lookup functions causing error message such as: CMake Error at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:148 (message):Ĭould NOT find Java (missing: Java_JAR_EXECUTABLE Java_JAVAC_EXECUTABLE Compiling From Source DistributionĮven when the Java JDK has been installed, CMake sometimes cannot find the location where it stands. Point 2 was made automatic in the newest versions of MariaDB. And of course, some JDBC drivers exist to be used with the matching DBMS.The java wrapper class files are available on your system.The Java SDK is installed on your system.New versions distribute a JavaWrappers.jar that contains all currently existing wrappers. The distributed JdbcInterface.jar file contains the JdbcInterface wrapper only. However, if the automatic compilation of it is possible after the java JDK was installed, the complete distribution of it is not fully implemented in older versions. The JDBC table type should be distributed with all recent versions of MariaDB.
