SendRedirect 不适用于 JSP Scriptlet

Question

I have a main.jsp.

Onclick on a button in main.jsp, I am launching my JSP scriptlet in another window. In the JSP Scriptlet, I am processing URL parameters and constructing the URL. URL construction works fine; I print it in the log file and manually open the link constructed.

I want to redirect this JSP scriptlet page to the new URL constructed (different domain), in order to send redirect.

I am putting this line at the end after constructing the URL.

response.sendRedirect(url);

When I try to sendRedirect nothing happens. Can anyone please help me figure out what's wrong?

Answer 1

To call the JavaScript in this scriplet use

url = urlBuffer.toString(); 
System.out.println("url from JS server="+url);    
%>
<script type="text/javascript">
window.location=<%=url%>
</script>

Answer 2

Onclick - is postback or callback event? Do you use ajax? When you using ajax request, you can add code to success event: document.location='some url'; When postback - document.location='<%= url%>';

Answer 3

window.location= .. didn't work for me.

I did this and it worked

 <script> 
window.location.href = "<%= url %>";
 </script>
