Interface ResourceResolver

public interface ResourceResolver

Returns an input stream for a given named resource, for example a path or URL or some other form of identifier. Thus, a resource might be read from the classpath, a jar file, a war file, a JDBC database, a JNDI context/data source, or similar.

An implementation might use ClassLoader.getResourceAsStream(String) or Class.getResourceAsStream(String) or ServletContext.getResourceAsStream(String) or a combination of these approaches, as deemed appropriate for the application-specific deployment/container environment, for example as follows:

 ResourceResolver myResolver = new ResourceResolver() {
     public InputStream getResourceAsStream(String resourceName) {
         ClassLoader loader = Thread.currentThread().getContextClassLoader();
         if (loader == null) { // there may not be a context class loader
             loader = MyClazz.class.getClassLoader();
         }
         return loader.getResourceAsStream(resourceName);
     }
 };
