lorenzo commented on ODE-260:
-----------------------------
Hi, this is still broken in version 1.3.5 using oracle and CLOB type for
ODE_MESSAGE.HEADER column.
If the column is empty oracle always returns an empty string (default behavior
for CLOB columns) and the check on line 105 of MessageDAOImpl fails.
Probably this should be changed to something like this
return (_header == null || _header.length() == 0) ? null :
DOMUtils.stringToDOM(_header);
Here is a fragment of the stack trace
Caused by: org.xml.sax.SAXParseException: Premature end of file.
at org.apache.xerces.parsers.DOMParser.parse(Unknown Source)
at org.apache.xerces.jaxp.DocumentBuilderImpl.parse(Unknown Source)
at org.apache.ode.utils.DOMUtils.parse(DOMUtils.java:623)
at org.apache.ode.utils.DOMUtils.stringToDOM(DOMUtils.java:549)
at org.apache.ode.dao.jpa.MessageDAOImpl.getHeader(MessageDAOImpl.java:105)
We will try to fix this using a VARCHAR2 instead of a CLOB for the header
column, expecting 4000 chars to be enough...
Bye
