Question

I have some static html content (included on a dynamically generated page) that I want to localize, i.e., help-en.html, help-fr.html and so on. In the JSP file where it is to be included I have a bean userLocale which is a string containing "en", "fr" and so on.

Thus a reasonable way to refer to the localized file would be:

help-${userLocale}.html

And a reasonable way to include it into the JSP would be:

<%@include file="help-${userLocale}.html" %>

However, this does not work, as the JSP compiler complains that it cannot file the file literally named "help-${userLocale}.html". Thus it seems that page directives are processed before EL code, and as such it s not possible to use EL inside page directives.

Is this correct, are there any workarounds, and/or are there any similarly simple ways to achieve the goal described above, without resorting to multiple choose/when tags or whatnot?

Answer 1

Use jsp:include instead. The @include is compiletime, not runtime.

E.g.:

<jsp:include page="help-${userLocale}.html" />
