WildFly - getting resource from WAR

I am using the following method to get a resource from WAR file in WildFly:

this.getClass().getResource(relativePath)

It works when the application is deployed as exploded WAR. It used to work with compressed WAR, too. Yesterday, I did a clean and rebuild of project in Eclipse, and it just stopped working.

When I check the resource root:

logger.info(this.getClass().getResource("/").toExternalForm());

I get this:

file:/C:/JBoss/wildfly8.1.0.CR1/modules/system/layers/base/org/jboss/as/ejb3/main/timers/

So, no wonder it doesn't work. It probably has something to do with JBoss module loading, but I don't know if this is a bug or normal behavior.

I found various similar problems on StackOverflow, but no applicable solution. One of the suggestions is to use ServletContext like so:

@Resource
private WebServiceContext wsContext;
...
ServletContext servletContext = (ServletContext)this.wsContext.getMessageContext()
        .get(MessageContext.SERVLET_CONTEXT);
servletContext.getResource(resourcePath);

But, when I try to obtain MessageContext in this manner, I get an IllegalStateException. So I am basically stuck. Any ideas?

Solution

  • I finally gave up and put my resource files in a new JBoss module, as described in this link.

    It works, but the downside is that there are two deployment targets so things are more complicated. On the upside, the size of the WAR file is reduced, and I don't have to redeploy the application if only some of the resources have changed.
