Pietro Iglio commented on HHH-2089:
-----------------------------------
Hi, sorry I have other committments and no time to work on the test case. I can tell you
that we have built a version of hibernate with this specific fix and we have been using it
for many months without problems.
The JDBC spec is quite clear about getSubString (see Clob javadoc), do you really need a
unit test?
Please look here:
http://java.sun.com/javase/6/docs/api/java/sql/Clob.html#getSubString(lon...
"pos - the first character of the substring to be extracted. The first character is
at position 1."
Hope this helps.
Ciao, Pietro
ClobType.setToXMLNode: could not read XML from Clob
---------------------------------------------------
Key: HHH-2089
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2089
Project: Hibernate3
Issue Type: Patch
Components: core
Affects Versions: 3.2.0.cr4
Environment: Hib 3.2.0cr4, database: any
Reporter: Pietro Iglio
Original Estimate: 0 minutes
Remaining Estimate: 0 minutes
I get "org.hibernate.HibernateException: could not read XML from Clob" trying
to retrieve a CLOB column as XML. I think I have found the reason of the bug in
org.hibernate.type.ClobType:
public void setToXMLNode(Node node, Object value, SessionFactoryImplementor factory) {
...
node.setText( clob.getSubString(0, len) );
...
}
According to the JDBC spec, the first character of Clob is at 1 position, so the correct
line should be node.setText( clob.getSubString(1, len) );
