Being able to set configuration using servletContextListener is reasonable request. However, I don't understand why would you need to read the configuration anywhere else than during group processing? Can you elaborate on your use-case?

In the taglib I'd like to contribute ;), I have two modes: one "production" mode and one "debug" mode. In the debug mode, you can get the unoptimized versions of your JS/CSS files. To get the unoptimized versions from the group name, we need the configuration :)

Basically, now, my taglib and also the one in wro4j-tag, we reimplement a version of the wro configuration file parser. Which is always inferior than the 'real' one, lacking many features, etc.

I think that's what the bug alf239/wro4j-tag#4 in wro4j-tag is about.

Fixed in branch 1.4.x

Usage:

1. Add listener in web.xml:

<listener>
  <listener-class>ro.isdc.wro.http.WroServletContextListener</listener-class>
</listener>

2. Access WroConfiguration or WroManagerFactory objects in any servlet:

ServletContextAttributeHelper helper = new ServletContextAttributeHelper(servletContext);
WroConfiguration config = helper.getWroConfiguration();
WroManagerFactory managerFactory = helper.getManagerFactory();
