Un-official patch for JOnAS2.0

JOnAS2.0 is one of the most powerful EJB server in the world.
EJB is the core architecture of J2EE. To build up the enterprise-oriented, network-oriented and system-independent Java components, EJB is essential architecture for the seriouse developer in the world. Since EJB 1.1 specification was released, we have desired some sophisticated EJB compliant server.
And now voilà JOnAS2.0 from Bull S.A..

How to store 2 bytes String into MySQL

This documentation describes how to store 2 bytes String into MySQL. MySQL is the world fastest SQL database. Though MySQL can be compiled for some specific character set (charset), such as Japanese ShiftJIS, it is desirable to store String with multiple charsets. For example, SQL database for e-commerce should accept Chinese GB2312 as well as Japanese EUC-JP. With MM.MySQL JDBC driver for MySQL, we can store Java String with 2 bytes characters, such as Japanese Shift_JIS, Chinese BIG5 or GB2312. JDBC PreparedStatement can be executed to query by Japanese language or Chinese on MySQL compiled just for ASCII. By OOP-Research.

How to use JOnAS (Enhydra) EJB server with MySQL

This article describes how to use JOnAS (Enhydra) EJB server with MySQL. JOnAS is the implementation of EJB specification Version 1.1, which supports JTA (Java Transaction API). And JOnAS requires JDBC 2.0 compatible driver, including the transaction. But MySQL supports the transaction (BEGIN, COMMIT and ROLLBACK) only in some situation. In the environment where the transaction is not supported, some configuration may be required to work with JOnAS EJB (Enterprise Java Beans) server. But don't worry. MM.MySQL JDBC driver is prepared for JOnAS.
