redirect after successful authentication

Hi Experts,

I am trying to redirect the users to a different portal component after they are successfully authenticated, as I need the details of the authenticated user, especially the R3Name that was mapped to. I have done the below modifications in umLogonPage.jsp of the logon application:

1. Deleted the form action:

onaction="<%=inPortal?"":logonBean.getLogonURL(proxy, null)%>";

   2. Deleted the onSubmit of the form:

?"onSubmit=\"javascript:addTenantPrefix();\"":""

  3. Changed the type of logon button to button from submit.

  4. Then, I have added the below script in the umLogonPage.jsp which is being called onclick of the logon button:

function payrollPnumCheck()
{  addTenantPrefix();  var logonAction =  "<%=inPortal?"":logonBean.getLogonURL(proxy, null)%>";  <%  boolean locked = PayrollStatus.isPayrollProcessing();  if((locked)){  %>  alert(location.pathname);  window.location.assign("http://zabrysvsapzhd:50000/irj/servlet/prt/portal/prtroot/com.dd.payrollProcessing.systemLocked");  <%  }else{%>  document.logonForm.action=logonAction;    document.logonForm.submit();  <%}%>
}

But, the portal is not being redirected after the authentication.

Please let me know what am I doing wrong here. I am quite new to js and jsp.

Thank you,

Sai
