NPE in NoRowsResultSetImpl.closeThis is a discussion on NPE in NoRowsResultSetImpl.close within the Apache forums in Application Servers & Tools category; I am seeing a strange problem trying to execute a simple delete statement.

It would be great if you could file a JIRA issue for this error and upload a test case to reproduce it, if you have one. From the stack trace, it looks like the NPE happens when the delete cascades to another table which references GEOFF__BLOG__USER, so the schema of the other tables would also be useful in the bug report. -- Knut Anders |
