another DBCP problem with tomcat 4.1.30, tomcat-5.0.27 and Oracle ApplicationServer-9.0.4

[Edson Alves Pereira]

        Hello dudes, i�m trying to store a value to a CLOB in my databse,
everything is fine with a simple Connection created with DriverManager, but
when i use DBCP from one of these servlet-engines i got the same error:

ava.sql.SQLException: invalid arguments in call

04/08/27 11:56:44       at appi.util.JUtils.getClob(JUtils.java:166)

        Here�s my code:

      //create a new temporary CLOB
      tempClob = CLOB.createTemporary(
        servlet_.getDbCon( ).getCon( ),
        true,
        CLOB.DURATION_SESSION );


        How can i fix it?

        Regards,
        Edson
