RE: how to solve java.lang.NoClassDefFoundError
Hi Richard, Your problem might be related to the driver class not available in your classpath. You can find the exact cause by looking at the _0002fconnect_00033_0002ejspconnect3_jsp_20.java:82) at line no. 82. Look at tomcat_home/work/../localhost/yourwebapp/jsp/_0002fconnect_00033_0002ejspcon nect3_jsp_20.java Can you check if your dependent jar (firebirdsql-full.jar) is placed under WEB-INF/lib folder. Placing dependent jar files here must solve your problems. hope it could help. regards SM -Original Message- From: Richard Drent (Drent IT BV) [mailto:[EMAIL PROTECTED] Sent: Monday, October 13, 2003 10:52 AM To: 'Tomcat Users List' Subject: how to solve java.lang.NoClassDefFoundError Can anyone tell me what this meens, and how to solve.

On line 82 is this //Load driver Class.forName(org.firebirdsql.jdbc.FBDriver); I cant tell you if you are using the correct package name for FBDriver.class. Well it would be wise enough if you could look into these jars below by exploding/opening it. Package declration and Driver class must be the ones that you use in your application page. -rwxrwxrwx1 adminsite1 336637 Oct 9 09:04 firebirdsql-full.jar -rwxrwxrwx1 adminsite1 308739 Oct 9 09:04 firebirdsql.jar all seems fine to me. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
