SYBASE Server EnterPrise Anywhere - JDBC 3.0 - executeUpdate

I'm trying to execute a stored procedure which basically does an insert. I've cooem across the following exception most of the time.


com.sybase.jdbc3.jdbc.SybSQLException: Arithmetic overflow during implicit conversion of SMALLINT value '340' to a TINYINT field .

      at com.sybase.jdbc3.tds.Tds.a(Unknown Source)
      at com.sybase.jdbc3.tds.Tds.nextResult(Unknown Source)
      at com.sybase.jdbc3.jdbc.ResultGetter.nextResult(Unknown Source)
      at com.sybase.jdbc3.jdbc.SybStatement.nextResult(Unknown Source)
      at com.sybase.jdbc3.jdbc.SybStatement.nextResult(Unknown Source)
      at com.sybase.jdbc3.jdbc.SybStatement.updateLoop(Unknown Source)
      at com.sybase.jdbc3.jdbc.SybCallableStatement.executeUpdate(Unknown Source)
      at org.jboss.resource.adapter.jdbc.WrappedPreparedStatement.executeUpdate(WrappedPreparedStatement.java:251)

SERVER : JBOSS EAP 4.2

This works fine when trying to update on the SYBASE SQL advantage. these are the input parameters
to the stored procedure.
