Hello group, I've seen other people with similar problems to mine, however none of the solutions presented are working here. Hopefully one of you can point me in the right direction.
I'm attempting to get Guice, JPA, and Shiro all to play nice with each other (and Wicket, once this is nailed down). I'm trying to deploy the following onto resin-4.0.29: *web.xml - * <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/javaee";

servletContextEvent) { servletContext = servletContextEvent.getServletContext(); super.contextInitialized(servletContextEvent); } @Override protected Injector getInjector() { ServletModule servletModule = new ServletModule() { @Override protected void configureServlets() { super.configureServlets(); install(new JpaPersistModule("serverPersistenceUnit")); install(new WebSecurityModule(servletContext)); filter("/*").through(PersistFilter.class); filter("/*").through(GuiceShiroFilter.class); } }; return Guice.createInjector(servletModule); } } *WebSecurityModule.class - *public class WebSecurityModule extends ShiroWebModule { public WebSecurityModule(ServletContext servletContext) { super(servletContext); } @Override protected void configureShiroWeb() { bindRealm().to(BaseRealm.class); addFilterChain("/**", ANON); } }* BaseRealm.class - * public class BaseRealm extends AuthorizingRealm { @Inject private SecurityDAO securityDAO; @Inject private UserDAO userDAO; public BaseRealm() { setName("BaseRealm"); } @Override protected SimpleAuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException { UsernamePasswordToken token = (UsernamePasswordToken) authenticationToken; String username = token.getUsername(); User user = securityDAO.findUserByUsername(username); if (user != null) { return new SimpleAuthenticationInfo(user.getId(), user.getPasswordHash(), getName()); } else { return null; } } @Override protected SimpleAuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) { Long userId = (Long) principalCollection.fromRealm(getName()).iterator().next(); User user = userDAO.find(userId); if (user != null) { SimpleAuthorizationInfo info = new SimpleAuthorizationInfo(); List<String> permissions = identifyPermissions(user); info.addStringPermissions(permissions); return info; } else { return null; } } private List<String> identifyPermissions(User user) { List<String> permissions = new ArrayList<String>(); if (user.isCreator()) { permissions.add("repository:create"); } for (Long id : securityDAO.findReposOwnedByUser(user)) { permissions.add("repository:delete:" + id); permissions.add("repository:" + id); } for (Long id : securityDAO.findReposAdministerableByUser(user)) { permissions.add("repository:" + id); } for (Long id : securityDAO.findReposContributableByUser(user)) { permissions.add("repository:" + id + ":create"); permissions.add("repository:" + id + ":view"); } for (Long id : securityDAO.findReposViewableByUser(user)) { permissions.add("repository:" + id + ":view"); permissions.add("repository:" + id + ":create:note"); } return permissions; } } And when I run it, I get this: 03 15:42:02.859] {main} com.google.inject.CreationException: Guice creation errors: 1) Error in custom provider, java.lang.NullPointerException while locating
