Informix JDBC Bug with Insert on PreparedStatement?

Is this a bug in the Informix JDBC Driver? My exception comes out as: -------------------------------------- java.sql.SQLException: System or internal error null at com.informix.util.IfxErrMsg.getSQLException(IfxErrMsg.java) at com.informix.jdbc.IfxSqli.sendExecute(IfxSqli.java) at com.informix.jdbc.IfxSqli.sendCommand(IfxSqli.java) at com.informix.jdbc.IfxSqli.executeCommand(IfxSqli.java) at com.informix.jdbc.IfxResultSet.executeUpdate(IfxResultSet.java) at com.informix.jdbc.IfxStatement.executeUpdateImpl(IfxStatement.java) at com.informix.jdbc.IfxPreparedStatement.executeUpdate(IfxPreparedStatement.ja va) at dtJDBCSession.runSQL(dtJDBCSession.java:231) --------------------------------------- I get ALOT of these "System or internal error null" problems and they come straight from the Informix JDBC driver. It always seems to happen on a PreparedStatement that is inserting into the database. This application of mine also updates an MS-Access database using the same code block (only exception is the ACCESS ODBC driver is loaded instead of the Informix one) and I have never received an exception on an insert statement. Could someone verify if this is a bug in the Informix JDBC driver and where we can get the latest/greatest. Thanks in advance, Theron Kousek
