Hi,
I’m experiencing the following error running a java web application on AIX version 5.3 with Oracle Database 10g Release 10.1.0.2.0? This error is only happened off and on, is there anything wrong with my java code or the database configuration?

java.sql.SQLException: Closed Statement

This exception normally is thrown when you try to reuse a callable statement that was closed already.
Check the stacktrace for the location of the offending line in your java-source.

hi Frank,
Thanks for your reply, this exception occur at the moment my program called the commit method, but my close method is at the finally block, so the connection should not be closed. This exception is only happened occasionally, if the case like what you mentioned, this exception will occur consistently.

Regards

The error does not have to occur consistently. There are more ways to close a transaction then to commit. It depends greatly on how you handle exceptions for example. Are all exceptions propagated to the java-block you are referring to, or are some handled somewhere halfway? (Either in a nice "when others" in the database-procedure, or a catch in a java method)
