我创建了 JBoss 登录模块,它运行良好。下面的示例:
public class UserLoginModule extends UsernamePasswordLoginModule {
private static UserService userService;
@Override
public void initialize(Subject subject, CallbackHandler callbackHandler,
Map<String, ?> sharedState, Map<String, ?> options) {
super.initialize(subject, callbackHandler, sharedState, options);
String wsdlUrl = (String) options.get("wsdlURL");
UserService.initialize(wsdlUrl);
userService = new UserService();
}
@Override
protected boolean validatePassword(String inputPassword,
String expectedPassword) {
boolean result = false;
try {
String response =
userService.getUserPort().checkOperator(getUsername(), inputPassword);
if(RESULT_OK.equals(response)) {
result = true;
} else {
result = false;
}
} catch(Exception e) {
log.error("Error when invoking UserService!", e);
}
return result;
}
}
该模块部署在 JBoss 的 common/lib 目录中。当系统尝试对用户进行身份验证并调用 validatePassword 方法时,一切都很好。
现在,当我尝试从 Web 应用程序(使用自定义登录模块的相同)中的 servlet 调用 UserService 时,会引发异常:

servlet 如下所示:
public class UserServlet extends HttpServlet {
private static Logger logger = Logger.getLogger(UserServlet.class.getName());
private static UserService userService;
@Override
public void init() throws ServletException {
super.init();
userService = new UserService();
}
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
doPost(req, resp);
}
@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
String result = null;
String login = req.getParameter("login");
result = userService.getUserPort().unblockOperator(login);
}
}
我正在使用 JBoss 5.1 EAP。任何想法如何解决这个问题?我的 Web 应用程序(包含 servlet)的 WEB-INF 目录是空的 - 那里没有 jar。
