Obtaining Unique Constraints via dbMetaData

[ak singh]

Hi All,
I created an unique constraint using the following queries :-

 ALTER TABLE <table name>ADD CONSTRAINT <const name>UNIQUE(<column name>) disable;
CREATE INDEX <name> ON <table name>(<column name>);
ALTER TABLE <table name>ENABLE NOVALIDATE CONSTRAINT <const name>;

this was done as the column on which the unique constraint was being added had some on unique values.

now when i perform

    dbMetaData.getIndexInfo(,,,,)

it doesn't list the above added unique constraint. this is being done to create a sql script from the source user(oracle)/database(mysql) to create its copy
any help for obtaining the constraint will be appreciated.
thanks and regards
