Subject: configuring jaas?
Date: Thu, 24 Jul 2008 16:24:04 -0700

Ok, I know I'm probably doing something stupid here but I can't find  
any decent tutorials that actually specify what specifically to do  
other than "Just create a jaas.config file and put in your project".

I am currently extending the SimpleWebdavServlet like so:
public Repository getRepository() {
         if (repository == null) {
             try {
                 repository = createNewRepository();
             } catch (NamingException e) {
                 e.printStackTrace();  //To change body of catch  
statement use File | Settings | File Templates.
             } catch (RepositoryException e) {
                 e.printStackTrace();  //To change body of catch  
statement use File | Settings | File Templates.
             }
         }
         return repository;
     }

     private Repository createNewRepository() throws NamingException,  
RepositoryException {
         String configFile = "repository.xml";
         String repHomeDir = "/Users/warnero/test-repo";

         Hashtable env = new Hashtable();
         env.put(Context.INITIAL_CONTEXT_FACTORY,  
"org.apache.jackrabbit.core.jndi"
             + ".provider.DummyInitialContextFactory");
         env.put(Context.PROVIDER_URL, "localhost");
         InitialContext ctx = new InitialContext(env);

         RegistryHelper.registerRepository(ctx, "repo", configFile,  
repHomeDir, true);
         return (Repository)ctx.lookup("repo");

     }

When I attempt to hit the repository at
localhost:8080/webdav-spike/repository

The servlet comes up with the authentication response, but if I just  
hit Ok then I get this error:
java.lang.NullPointerException

.server.SessionProviderImpl.getSession(SessionProviderImpl.java:55)

.webdav 
.server.AbstractWebdavServlet.service(AbstractWebdavServlet.java:182)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:803)

I have a jaas.config file located in my web directory (both WEB-INF  
and classes) :
Jackrabbit {
org.apache.jackrabbit.core.security.SimpleLoginModule required  
anonymousId="anonymous";
};

And this is also setup in my repository.xml file

<Security appName="Jackrabbit">
         <!--
             access manager:
             class: FQN of class implementing the AccessManager  
interface
         -->
         <AccessManager  
class="org.apache.jackrabbit.core.security.SimpleAccessManager">
             <!-- <param name="config" value="${rep.home}/access.xml"/ 
 > -->
         </AccessManager>

         <LoginModule  
class="org.apache.jackrabbit.core.security.SimpleLoginModule">
            <!-- anonymous user name ('anonymous' is the default  
value) -->
            <param name="anonymousId" value="anonymous"/>
         </LoginModule>
     </Security>

All of this is fairly straightforward from the Web site, I can't seem  
to find in the jackrabbit-webapp an actual jaas.config file in the  
war, so I'm not sure what I need to do to set this up properly.

Thanks in advance!
