[jira] Commented: (CAY-1307) Error committing CLOB on Oracle8

["Bryan Lewis (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CAY-1307?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12776431#action_12776431 ] 

Bryan Lewis commented on CAY-1307:
----------------------------------

Comparing the Cayenne2 and 3 sources.  Cayenne2 had this line in its
OracleLOBBatchAction.writeClob() methods:

        Method getWriterMethod = OracleAdapter.getWriterFromClobMethod();

Cayenne 3 has:

            Writer out = clob.setCharacterStream(0);

I believe the former line would still work, since OracleAdapter still
provides the writerFromClobMethod.
