    Hmm, that message is odd - it suggests that the JDBC driver is returning an OracleClobReader instead of a java.sql.Clob, which is what it's supposed to return. We have not been able to reproduce this problem locally with either ojdbc5.jar or ojdbc14.jar connecting to 10g.

    Could you try changing the type of the field in the .ds.xml file from "text" to "clob", and let us know if that makes the problem go away? Also, what exact version of Oracle are you using?
    I'm using 2012-03-20_v8.2p/PowerEdition and we're migrating to oracle 11g release 2, using ojdbc6_g.jar driver:

    Implementation-Vendor: Oracle Corporation
    Implementation-Title: JDBC debug
    Implementation-Version: 11.2.0.3.0
    Repository-Id: JAVAVM_11.2.0.3.0_LINUX_110823

    and while reading a clob I obtain an OracleClobReader (tested with type="text" or type="clob")

    is it normal?

    the listgrid bound to the datasource which has this clob field works normally.
    But I have a DMI method where I fetch records from the datasource and then I need to convert the clob field to a string...previously I was doing like this:
    Code:
            CharArrayReader richText = (CharArrayReader) map.get("RICH_TEXT");
            if (richText == null) {
                return;
            }
            int ch = 0;
            richText.reset();
            StringBuffer sb = new StringBuffer("");
            while((ch = richText.read()) != -1) {
                sb.append((char) ch);
            }
            richiesta.put(nomeParametro, sb.toString());
    but now I can't cast the OracleClobReader to CharArrayReader, so I'm stuck :-(

      well, after a more careful thinking, casting to a java.io.Reader instead of CharArrayReader, and removing the .reset (which gives an exception in Italian "Contrassegno non valido o non impostato" which sounds something like "marker not set or invalid"), I manage to convert the OracleClobReader to a string.

      But there's another problem, which I wonder if it's a bug (maybe related to the return of an OracleClobReader?):

      if I try to set null in the type="clob" field, I got this exception (with oracle 10g it was working):

      but if I use type="text", then it works

        We have corrected this issue with explicit null values in Clob fields - it will be in tomorrow's (April 10th) nightly builds of 8.3d/3.1d and 8.2p/3.0p
