Oracle9i Intermedia cannot set properties

Question

hai, i want to ask why Oracle9i in my server cant set properties for mp3 or wav (audio length can be recognized, but the value of mimetype and format is ???). but when i use another Oracle9i in another computer, i can. when i check with System.out.println (Java), the file uploaded with servlet, i use method OrdHttpUploadFile.getMimeType() its work (the output is "audio/mpeg") but when OrdAudio.getMimeType() its output is "???"
any idea

Answer 1

no exception at all
i'm using Java servlet for upload and retrieve media, with JBoss as Application Server,
this code is for upload:
oracle.jdbc.driver.OracleCallableStatement insertAudio =
(oracle.jdbc.driver.OracleCallableStatement)
conn.prepareCall("BEGIN "+
"INSERT INTO audiotab VALUES(1,:1,:2,:3,:4,:5,SYSDATE," +
"ORDSYS.ORDAudio.init(),:6,:7,:8) " +
"RETURN audioid INTO :9 ; END;");
... (fill bind variable)
insertAudio.executeUpdate();
oracle.jdbc.driver.OraclePreparedStatement selectAudio=
(oracle.jdbc.driver.OraclePreparedStatement)
conn.prepareStatement(
"SELECT * FROM audiotab WHERE audioid=? FOR UPDATE ");
... (fill bind variable)
oracle.jdbc.driver.OraclePreparedStatement updateAudio=
(oracle.jdbc.driver.OraclePreparedStatement)
conn.prepareStatement(
"UPDATE audiotab SET audiofile=:1 WHERE audioid=:2");
.... (fill bind variable)
OracleResultSet rs=(OracleResultSet)selectAudio.executeQuery();
if(rs.next())
OrdAudio ord=(OrdAudio)rs.getCustomDatum(8,OrdAudio.getFactory());
data.loadAudio(ord);
formData.release();
updateAudio.setCustomDatum(1,ord);
updateAudio.setLong(2,audioid);
updateAudio.executeUpdate();
conn.commit();
there is one thing that maybe weird (for me), when i'm using Toad from Quest Software, i look the ORDAudio, THERE IS audio/mpeg as its MIME type, and other properties was right, so what happen with this?? is it because of Java, Oracle, or web server, i'm using tomcat 4 before JBoss 4, and the result was same.
and there is one thing that disturbing me, why method getCustomDatum() from OracleResultSet was deprecated, although it works but its annoying, is there other method to get the ORDAudio and other ORD.
