How to getapplicationContext scoped variable in JSF?

wquraishi Sep 24, 2007 3:39 PM

Hello all,

I have an application scoped variable which I would like to use in my JSF code. It contains a server specific value indicating the base URL for the apache server serving the static content (images). The variable gets set in a filter and I want to add it as part of the URL for an h:graphicImage something like:

<h:graphicImage url="#{APACHE_BASE_URL}/#{blogPhoto.photoUrl}" rendered="#{blogPhoto.photoUrl ne null}" styleClass="boxed"/>

Apache Base URL is correctly populated in the filter. But I can't seem to get anything out in the XHTML page.

Thanks for your help.

this is the code setting the values in the filter:

 if (APACHE_URL == null | APACHE_DIR == null) {
 // set the values in the application context
 org.jboss.seam.contexts.Contexts.getApplicationContext().set(
 "APACHE_URL", APACHE_URL);
 org.jboss.seam.contexts.Contexts.getApplicationContext().set(
 "APACHE_DIR", APACHE_DIR);
 }

APACHE_BASE_URL is not being set. It looks like you are setting APACHE_URL and APACHE_DIR

Sorry the first post should actually say APACHE_URL (typo).

Nevermind...so stupid and too quick to post. Got it..pretty self explanatory too:

In JSF:
The Apache DIR is: <h:outputText value="#{applicationContext.get(APACHE_URL)}"/>
