On July 3rd, 2006, JDbMonitor v1.0 was released.  It is a tool to monitor performance of SQL statements in any Java/J2EE applications without code changes.  With JDbMonitor, you can determine the application's performance and analyze problems down to specific SQL statement. 

JDbMonitor sits between Java application and the applications' JDBC driver.  It intercepts communication between Java application and the underlying JDBC driver. 

Java Runtime Environment (JRE) or Java Development Kit (JDK) 1.5 is required to use JDbMonitor client.
