Execute Custom code to do a warning message on SSHR Manager Appraisal form

Question

Hello - I do not know much about Java/OAF, but I'm really trying to learn! Here is my requirement,
please help me in getting this done.
Requirement : On Employee appraisal form, they will have their yearly objectives and their weight percentages.
These objectives weight percentage is in per_appraisal table attribute1 field(DFF).
The total weight percentage of an employess all objectives should be equal 100.
When manager will login to give them a final rating, the total of all weights percentages should be equal to 100,
if not I have to through a warning message on the Manager's appraisal form(CompFinalRatingsCO).
To calculate the total weight, we can certainly write a small pl/sql function or a procedure.
But how can I execute that code and show a warning message on SelfService HR Manager Appraisal form?
Thanks in advance for your help.
Thanks

Answer 1

1) extend the CO attached to your page.
2) Capture the Button in Processformrequest of your extended CO.
3) Call a plsql function or procedure with OUT param which will return whether 100% weightage has been entered or not.
If Not, then throw warning message.
Here is the way to call Plsql proc with OUT param.
String sql =
"BEGIN bcr12_mapping_tool_procs_pkg.XXBCR12_HAS_MANDATORY(:1,:2); END;";
OracleCallableStatement cs =
(OracleCallableStatement)am.getOADBTransaction().createCallableStatement(sql,
1);
try {
cs.registerOutParameter(2, 1, 0, 2000);
cs.setString(1, int_name);
cs.execute();
String new_status = cs.getString(2);
cs.close();
if ("Y".equals(new_status.trim())) {
throw new OAException("Please enter all mandatory column highlighted.",
(byte)0);
} catch (Exception ex) {
throw new OAException(ex.getMessage());
}
