Java and JavaScript in the Database

We have a jdbc application that reads from one Oracle table and builds a prepared statement to do an insert into a different table.

We are getting the following exception:
java.sql.SQLException: Numeric Overflow

oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112)

oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:146)

at org.iobis.Moveit.moveit(Moveit.java:85)
at org.iobis.Moveit.main(Moveit.java:327)

The line of code referenced (Moveit.java:169) is part of a switch statement that picks the appropriate data type:
public void setPlaceholderValue ( int placeHolderNum, ResultSet rs, String oracleColumnName, PreparedStatement stmt ) throws Exception {

int columnIndex = rs.findColumn(oracleColumnName) ;
int columnType = rs.getMetaData().getColumnType(columnIndex) ;

if ( rs.getObject(oracleColumnName) != null ){
switch (columnType) {
case Types.VARCHAR: stmt.setString(placeHolderNum, rs.getString(columnIndex)); break;
case Types.INTEGER: stmt.setInt(placeHolderNum, rs.getInt(columnIndex)); break ;
case Types.DATE: stmt.setDate(placeHolderNum, rs.getDate(columnIndex)); break;
case Types.NUMERIC: stmt.setInt(placeHolderNum,rs.getInt(columnIndex)); break ;
case Types.FLOAT: stmt.setFloat(placeHolderNum, rs.getFloat(columnIndex)); break ;
case Types.TIMESTAMP: stmt.setTimestamp(placeHolderNum, rs.getTimestamp(columnIndex)); break ;
default: throw new SQLException("The result set column type " + rs.getMetaData().getColumnType(columnIndex) + " was not recognized. see http://java.sun.com/j2se/1.5.0/docs/api/");
}
} else {
stmt.setNull(placeHolderNum, columnType);
}
}

This utility has been used many times with no problems but never on the table that was being moved when this exception occurred. This table has 10 columns of type NUMBER 22. One of these is a recently added ID column. The value of the id column was probably the same as the record number when the exception occurred, 2,534,151.

Any help or advice would be appreciated,
