Which action called on click of Logon Button in EP 7.4

Hello Everyone,

I have a requirement to call a BSP page on click of Login button in EP 7.4.

I check the logonPage.jsp but could not figure out where event is going on click of Logon button and which page/servlet is being called, as I want to update my code there to call specific BSP page.

Can we directly achieve this if not then what other options do we have?

Thanks in advance for your help.

Regards,

Rajesh
