JSP Database Access : 500 Internal Server Error

Question

Hello everybody!
My JSP code run until I write the next:
Class.forName("com.ms.jdbc.odbc.JdbcOdbcDriver").newInstance();
Connection connDB = DriverManager.getConnection("jdbc:odbc:OracleDB", "carlos_prb", "carlos_prb");
Statement smentDB = connDB.createStatement();
ResultSet rsDB = smentDB.executeQuery("SELECT * FROM websites");
rsDB.close();
smentDB.close();
connDB.close();
I need to access an Oracle Database. This code run in a java class, but not here. If I try to display the portlet the next message appears:
Error: The listener returned the following Message: 500 Internal Server Error
Somebody can help me, please?

Hi Charles,
Thank you for yout help. I tried change this jar file for old one from
jdeveloper 9 RC, but problem is still the same.
I reviewed bcj4html.jar file too, and I did not discover problems in RequestParameters class.
Have you any idea how to solve it ? I am sure that in project properties "libraries" I have selected
all possible BC4J classes. (installation of DS and 9i database has made week before on new XP)
Thank you very much for more info :)
