Is there any way to add the regex validation for credit card number along with the text box of credit card is not null?

I have the credit card number format regex it is working as expected but if i need to add the not null as well means how to add it?

My doubt is will the same normal regex will work in ADF as well?

The regex i checked was,
/^$|s+/

along with the pattern like this “((4|5)[0-9]{15}|^9[7][0-9]{15}|^3[5][0-9]{15}|^6[5][0-9]{15}$)”

please suggest the correct regex validator for the Oracle ADF

with the number format validation not null validation also should be added which should get supported by oracle ADF.

Thanks in advance
