+Seam Environment Configuration
+==============================
+
+Example:
+
+The following bean will cause the string "Hello World!" to
+be bound to the JNDI name java:global/msg when the archive
+that contains this bean is deployed.
+
+import org.jboss.seam.envconfig.Bind;
+import org.jboss.seam.envconfig.EnvironmentBinding;
+
+public @EnvironmentBinding class EnvironmentVars
+{
+ @Bind(jndiAddress="msg") private final String msg = "Hello
World!";
+}
+
+You can then inject the value into a managed bean as follows:
+
+@Resource(lookup = "java:global/msg") String msg;
+
