Original URL from Pretty Context

Pretty-faces is a simple URL rewriting engine. All sorts of SEO is possible and it is really easy. We faced very small problem while using this long with Prime-Faces. The problem us file upload in Ajax environment stopped working because some how it is not able to identify rewritten URL.

Solution

After some Investigation, I found that we can make file upload work, if some how we can find actual url along with query parameter from pretty faces and add this on the h:form component action. I tweaked some solutions available in the fourms and created a new one to support my requirement.

Sample Pretty Faces Rewrite Rule

	<url-mapping id="blog">
	<pattern value="/blog/#{url}" />
	<view-id value="/blog.jsf" />
	</url-mapping>

So the URL in address bar looks like

http://host.com/blog/sample-post

The Rewrite Rule maps the request internally to

http://host.com/blog?url=sample-post

Actual URL Generation Code

	PrettyContext context = PrettyContext.getCurrentInstance(fc);
	if (context.isPrettyRequest()) {
	StringBuilder builder = new StringBuilder(context.getContextPath());
	UrlMapping mapping = context.getCurrentMapping();
	builder.append(mapping.getViewId());
	QueryString query = QueryString.build(context.getRequestQueryString().getParameterMap());
	Map < String, String[] > params = new HashMap < String, String[] > ();
	List < PathParameter > parameters = mapping.getPatternParser().parse(context.getRequestURL());
	for (PathParameter parameter: parameters) {
	params.put(parameter.getName(), new String[] {
	parameter.getValue()
	});
	}
	query.addParameters(params);
	builder.append(query.toQueryString());
	return builder.toString();
	}
	return null;
