my code is

     this.jdbcTemplate.update(SOME_SQL_UPDATE, new PreparedStatementSetter() {
                    public void setValues(PreparedStatement ps) throws SQLException {
                        ps.setBoolean(1, myObj.isVal1());
                        ps.setString(2, myObj.getVal2().toString());
                    }
                });

public class myObj {
    private boolean val1;
    private Enum val2;
}

my db column for boolean is number(1,0) and my set string column is varchar.

Note: I am using spring 1.2 and currently upgrading to spring 3.

What could be wrong?

How can i fix this?

Answer 1

Are you sure myObj is not null? It looks like it could be the only object that could be null in that statement. Could you do a simple null check on the object inside the method to confirm?
