Jeff,
I did read your posting at
http://www.mail-archive.com/[email protected]/msg06898.html
already before sending this question. I could not understand how/where do
I modify the code to consider proxy class.
My getOpaqueValue() displays ResultSet class is: $Proxy2, not
ResultSetLogProxy.
The program DOES WORK if I turn off logging.
I tried something like this:
public Object getResult(ResultGetter getter) throws SQLException {
// if (getter.getResultSet() instanceof OracleResultSet) {
OPAQUE opaqueValue = getOpaqueValue(getter);
if (opaqueValue != null) {
XMLType xmlResult = XMLType.createXML(opaqueValue);
return xmlResult.getDOM();
} else {
return null;
}
// } else {
// throw new UnsupportedOperationException("XMLType mapping
only supported for Oracle RDBMS");
// }
}
private OPAQUE getOpaqueValue(ResultGetter getter) throws SQLException
{
java.sql.ResultSet rs = getter.getResultSet();
System.out.println("ResultSet class is: " + rs.getClass());
// ResultSetLogProxy rsProx = (ResultSetLogProxy)rs;
OracleResultSet ors =
(OracleResultSet)ResultSetLogProxy.newInstance(rs); //--- THROWS
ClassCastException
OPAQUE op = null;
if (getter.getColumnName() != null) {
op = ors.getOPAQUE(getter.getColumnName());
} else {
op = ors.getOPAQUE(getter.getColumnIndex());
}
return op;
}
Thanks

Re: Exception "XMLType mapping only supported for Oracle RDBMS"
The code in the wiki article does not take into account the fact that
iBATIS logging changes the normal classes to proxy classes. First thing
to do is turn off logging to see it will work. Second thing, the code
must be modified to account for the proxy class if logging is enabled (add
another instanceof check for the proxy class, then unwind the embedded
"real" class).
See here for more information:

I am using code as directed in this url:

It throw UnsupportedOperationException("XMLType mapping only supported for

I have logger set to DEBUG mode.
I tried displaying class from ResultSet like :
java.sql.ResultSet rs = getter.getResultSet();
System.out.println("ResultSet class is: " + rs.getClass());
The cosole displays

I am using JDeveloper 10.1.3.1
What should I change in my code to make it working?
Thanks
