Pietro Iglio commented on HHH-2089:
-----------------------------------
OK, I'll try to provide a testcase. These two links clearly show the bug, however:
http://fisheye.jboss.org/browse/Hibernate/trunk/Hibernate3/src/org/hibernate/type/ClobType.java?r=7644#l142
(line 142) with the javadoc of Clob.getSubString():
http://java.sun.com/j2se/1.5.0/docs/api/java/sql/Clob.html#getSubString(long,%20int)
Parameters:
pos - the first character of the substring to be extracted. The first character is at position 1.

> 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) );
