Method Detail

• getEnvEntry

  public static <T> T getEnvEntry(String name)

  Returns the named environment entry for the deployment component from where this is called. From within the web module this returns the <env-entry-value> of a <env-entry> in web.xml associated with the given <env-entry-name>.

  Note that the name used here is relative to "java:comp/env", which is exactly as it appears in web.xml.

  Example:
  
  web.xml

   <env-entry>
          <cont>org.omnifaces.TEST_INTEGER</env-entry-name>
          <env-entry-type>java.lang.Integer</env-entry-type>
          <env-entry-value>10</env-entry-value>
   </env-entry>
   

  Lookup in Java using relative name

   Integer test = JNDI.getEnvEntry("org.omnifaces.TEST_INTEGER");
   

  Lookup in Java using full JNDI name

   Integer test = JNDI.lookup("java:comp/env/org.omnifaces.TEST_INTEGER");
   

  Note that even the "full JNDI name" is relative to the "deployment component" from which the lookup is done. To use a true global JNDI name an additional <lookup-name> should be specified in web.xml.

  Environment entries can also be injected using Resource.

  Parameters:

  name - the environment entry name relative to "java:comp/env".

  Returns:

  The environment entry value associated with the given name, or null if there is none.
