I'd guess that the BaseIbatisDAO is failing to initialize properly, then causing the exception you are seeing - if the initialization fails, the class does not load, so later classes that rely on it can't find it.
I'd look there for issues - maybe step through it with a debugger. Larry On 4/13/07, [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote:

Jun, The problem is that Tomcat can't find your BaseIbatisDAO class. Is the package in your WEB-INF/classes directory? -Richard -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Friday, April 13, 2007 9:01 AM To: [EMAIL PROTECTED] Subject: java.lang.NoClassDefFoundError error again, need help! I am trying to use iBATIS in jDeveloper 9 and Tomcat 5.0.28. I keep getting error: java.lang.NoClassDefFoundError, under \WEB-INF\lib\ there are : ibatis-2.3.0.677.jar, log4j-1.2.14.jar; commons-logging-1.1.jar... and other struts jar.
