Hello Henry,
I had the same problem. You must use a TypeHandler which handles the string
on java to a clob on database site. In spring (www.springframework.org) you
can find custom type handler in package
"org.springframework.orm.ibatis.support". I've written following
TypeHandler:
public class ClobToStringTypeHandlerCallback implements TypeHandlerCallback
{
/**
* [EMAIL PROTECTED]
*/
public void setParameter(ParameterSetter setter, Object parameter)
throws SQLException {
String s = (String) parameter;
if (s != null) {
StringReader reader = new StringReader(s);
setter.setCharacterStream(reader, s.length());
} else {
setter.setString(null);
}
}
/**
* [EMAIL PROTECTED]
*/
public Object getResult(ResultGetter getter) throws SQLException {
String value = "";
Clob clob = getter.getClob();
if (clob != null) {
int size = (int) clob.length();
value = clob.getSubString(1, size);
}
return value;
}
/**
* [EMAIL PROTECTED]
*/
public Object valueOf(String s) {
return s;
}
}
See the iBatis doc how to use TypeHandlers in sql map configuration files.
If something is not clear to you don't hesitate to ask.
Cheers,
Martin

Subject: Re: 32k limitations for clob/blob?
Is there anyone who have a working-code for insert CLOB and LONG data
type in Oracle?
-Henry
P.S.
Check the statement (update failed). - is a missleading error message from
iBatis. I did use INSERT command.
