Hello
I work with JBoss + Eclispe + Firebird. I've written a ejbStore procedure like
that:
public void ejbStore()
{
System.out.println("Project enter: ejbStore");
Connection connection = null;
PreparedStatement ps = null;
try
{
connection = getConnection();
String select = "update PROJECT set FK_LECTURER_ID = ?,FK_SUBJECT_ID = ?,"+
" PROJECT_DAY = ?,PROJECT_HOUR = ?,CLASS_NUMBER = ?, STUDENTS_IN_GROUP = ?," +
" NUMBER_OF_GROUPS = ? where PROJECT_ID = ?";
ps = connection.prepareStatement(select);
ps.setInt(1,this.getFk_lecturer_id());
ps.setInt(2,this.getFk_subject_id());
ps.setString(3,this.getProject_day());
ps.setInt(4,this.getProject_hour());
ps.setInt(5,this.getClass_number());
ps.setInt(6,this.getStudents_in_group());
ps.setInt(7,this.getNumber_of_groups());
ps.setInt(8,this.getProject_id());
ps.executeUpdate();
}//try
catch (Exception e)
{
System.out.println("Project wyjatek: ejbStore");
e.printStackTrace();
}
finally
{
try
{
if (ps != null ) ps.close();
}
catch (Exception e)
{}
try
{
if (connection != null) connection.close();
}
catch (Exception e)
{}
}//finally
System.out.println ("Project exit: ejbStore");
}//ejbStore
During testing no exception appears and it seems to work. When I call a get*
method after a set* method a new value seems to be stored in the data base. But
when I execute a sql query there are no changes in the table. Does anybody know
what can be wrong. I think that a problem is somewhere else but I am not sure.
One more thing, ejbCreate and ejbRemove method works properly.
