Login Language box on Login page for ISA

Hi,

I want to enable language selection box on Login page of ISA. I have deployed standard B2B and shop admin application on my local. and created JCO connection for both with same standard user name "weblogin"

I use SAP ECC and checked comunication language in SU01 for weblogin and it has near about 10 different languages.

Now when I go to shop admin login page I can see Language select box along with "user ID" and "Password" box but when I go to standard B2B login page I see only "User ID" and "Password" input box but not able to see "Language" Box.

I checked "login.jsp" file in both application and came to know that both are using the same code to populate language box on login page.

Both application use same backend syatem and same parameter in both JCO connection in XCM of both application.

Can any one help me why I am not getting language box on B2B standard login page. Where I have to make changes so I can populate language box on B2B login page.

I really appreciate If someone guide me.

Thanks in Advance.
