How to escape strings server-side

[ob1kanobee]

Hello,

I am trying to incorporate the escape/unescape function written in javascript within a java process page.
It seems simple enough, but I cannot get it to work.

Code:

<script language="javascript">
function doEscape(sFileName) {
if(sFileName != null && sFileName != "") {
return escape(sFileName);
}
</script>

Here's the Java code calling the javascript function. The getAbsolutePath returns me the path and filename being imported. I need for users to be able to upload filenames with ascii and non-ascii characters as well as punctuations, etc.:

<%
sFilenameLocal = fCustomerSat.getAbsolutePath();
sFilenameLocal = %>doEscape(<%=sFilenameLocal%>)<%;
System.out.println("FileName is: " + sFilenameLocal);
%>



I keep getting an "incompatible types" error even though the variable sFilenameLocal is a string variable.

I also tried putting quotes around the java sFilenameLocal variable with basically the same results.


What am I missing here? Any help will be appreciated. TIA

Ask yourself these questions :

1) Does the Java part of a JSP page (within the scriptlet tags) execute on the client, or the server ?

2) Does Javascript exectute on the client or server ?

When you can answer these questions correctly, and understand them, you will be able to answer your own question

Thanks for the response.
Java executes on the server side and Javascript executes on the client side. Now that I understand what's going on, is there a workable solution for this scenario or a similar function in Java for the escape and unescape functions?

Try these two classes :

http://java.sun.com/j2se/1.4.2/docs/api/java/net/URLEncoder.html
