Oracle OAF:Date Field -set min and max date

Hi All,

Its long time i have written anything interesting..too much occupied in job and not able find time to write anything...

Now a days i am working some interesting projects.. projects just to enhance user experience in using oracle projects.

Instead of multiple clicks in OOB we are developing a single screen to perform the same transaction...
and one screen to view all the data he need.
 we are working developing Custom OAF page and integrating with Oracle OOB.

OOB-- Out of box(oracle standard pages)

One of the requirements was to control the calendar in the date field..our requirement was to stop user from selecting any date in the past.

There are multiple approaches for doing this either in complete java or JAVA and PLSQl
here i am presenting one of the approaches of getting date from DB
--Get page connection

Connection conn = pageContext.getApplicationModule(webBean).getOADBTransaction().getJdbcConnection();

--sql query

String selectSQL = "select NVL(TO_DATE (fnd_profile.VALUE ('XX_GLOBAL_DATE'),'DD-MON-RRRR'),SYSDATE) date1 FROM DUAL";

System.out.println("SQL: "+selectSQL);

--parse the sql

PreparedStatement stmt = conn.prepareStatement(selectSQL);

--execute query

ResultSet rs = stmt.executeQuery(selectSQL );

System.out.println("RS: "+rs);

while (
java.sql.Date date = rs.getDate("date1");
--get the date field handler
OAMessageDateFieldBean dateField = (OAMessageDateFieldBean)webBean.findIndexedChildRecursive(stat_date);
--set the minimun value
similary we can set the max date also ...But make sure the date is in sql date type.

But one catch is  if user dont use the calendar and type date in the field the system will allow a past date.To over come this issue
you need to have a validation logic defined either in the set attribute of the VO or a error raised from DB if you are not comfortable in java :)
