[seam-issues] [JBoss JIRA] (JBSEAM-4905) parseStylesheet does not work on JBoss AS 7

[Philippe Guinot (JIRA)]

    [ https://issues.jboss.org/browse/JBSEAM-4905?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12675165#comment-12675165 ] 

Philippe Guinot commented on JBSEAM-4905:
-----------------------------------------

A solution I can see is the replace getClass() by FacesContext.getCurrentInstance().getExternalContext(), then it may be able to load from current WebContent.

However, I'm not really sure that everyone deploys the css into the WebContent...

> Indeed, if the urlString is a relative url, the current class' classLoader won't be able to get the resource from the WebContent. The current application context should be used instead.
> As a workaround I tried to pass the JNDI path of the resource which is an absolute URL. But it does not work, indeed such an URL as the following form 'jndi:/default-host/mypath/mystyle.css' and so does not include the '://' pattern.
