therefore the driver will not allow you to enable
same time.
• New SQLState Codes: Connector/J 3.1 uses SQL:1999 SQLState codes returned by the MySQL
server (if supported), which are different from the legacy X/Open state codes that Connector/J
3.0 uses. If connected to a MySQL server older than MySQL-4.1.0 (the oldest version to return
SQLStates as part of the error code), the driver will use a built-in mapping. You can revert to the old
mapping by using the configuration property useSqlStateCodes=false.

values have no character set, so they cannot be converted to java.lang.Strings without
BLOB
data loss or corruption.
To store strings in MySQL with LOB behavior, use one of the

• Debug builds: Starting with Connector/J 3.1.8 a debug build of the driver in a file named

Starting with Connector/J 3.1.9, we do not ship the
in the JAR archives that ship with the driver.
Do not use the debug build of the driver unless instructed to do so when reporting a problem or bug,
as it is not designed to be run in production environments, and will have adverse performance impact
when used. The debug binary also depends on the Aspect/J runtime library, which is located in the
src/lib/aspectjrt.jar
20.3.3.4. Installing from the Development Source Tree
To install MySQL Connector/J from the development source tree, make sure that you have the
following prerequisites:
• A Bazaar client, to check out the sources from our Launchpad repository (available from
bazaar-vcs.org/).
• Apache Ant version 1.7 or newer (available from http://ant.apache.org/).
• JDK 1.4.2 or later. Although MySQL Connector/J can be be used with older JDKs, compiling it from
source requires at least JDK 1.4.2. To build Connector/J 5.1 requires JDK 1.6.x and an older JDK
such as JDK 1.5.x; point your
To check out and compile a specific branch of MySQL Connector/J, follow these steps:
1. Check out the latest code from the branch that you want with one of the following commands.
