Java EE (Java Enterprise Edition) General Discussion

Hi i am having a button close button as shown below inside my JSP Page

<INPUT TYPE='SUBMIT' VALUE='CLOSE' ONCLICK='back()'/>

Upon clicking on this button it should be redirected to an another jsp page .
(I dont want to use window.open functionality as lot of parameters need to passed )

Please tell me what should be written here ;

function back()
{
// Here code needed 
}

Thank you for reading .
