Subject [jira] [Commented] (DBCP-349) Insert clob or blob with oracle connection crashes software
Date Mon, 02 Jul 2012 07:40:48 GMT

    [ https://issues.apache.org/jira/browse/DBCP-349?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13404921#comment-13404921
] 

Renaud Bruyeron commented on DBCP-349:
--------------------------------------


FYI, the stacktrace is missing the top of the stack, but in our case (a spring/hibernate application)
there is a workaround at the application level: one must use CommonsDbcpNativeJdbcExtractor
instead of SimpleNativeJdbcExtractor.
