Are you declaring the String in a Java snippet or Javascript?

If chgLocURL is a scripting variable, then it's not visible to the EL. You should never be mixing scriptlets in with the EL. In fact, you should never be using scriptlets at all.

As it's not valid JavaScript syntax, I think it's clear that it's a Java scriptlet.

i am using below
<%

String chgLocURL ="https://google.com";

%>
<jsp:forward page= <%=chgLocURL%> />

See my reply. Scriptlets are 10 years out of date. Read this JspFaq entry.

In any case, you cannot forward to a resource outside of the current web application.

Please help me out with this code fix:

my url is in strnig.
and i need to forward to this new url which is in my string, how should i forward. Please can somebody provide me with right code snippet?

[Bear Bibeault]

Once again: you cannot forward to a resource outside of the current web app.

You'll need to redirect.

Sorry for the confusion. Actually the url is ini scope of my app only. google.com is just an example. Dont get confuse with this. Only thing i want to know if in anyway i can use this string so that i can forward to the url that is in the string.

Thanks

This is called a "red herring" and is to be avoided. Show us real data, or as real as possible, and you won't waste the time of the people trying to help you. Please read AvoidRedHerrings.

Too late.

Only thing i want to know if in anyway i can use this string so that i can forward to the url that is in the string.

When you show us the real code, and show us the real errors that are occurring maybe we can help you.

Hi .

Apologies for my previous reply.

Below is my code snippet:

<%
String chgLocURL ="/jsp/welcome.jsp";

%>
<jsp:forward page="{<%=chgLocURL %> }"/>


It is not working.
Please help me how can i use this string. I just need to forward to the path stored in string chgLocURL from my current jsp in my application.
Please help with the code snippet.
Once again apologies for my previous post.
Thanks.

Its giving page not found error.

[Bear Bibeault]

Does the page exist? If so, where? Does it work when you hard-code the path into the directive? You're still very far from giving us complete information.

Alternatively you can try using

<%response.sendRedirect("url");%>

difference between forward and redirect

[Bear Bibeault]

They do completely different things and are not interchangeable.
