Deploying Struts 2 project in JBOSS 7

I am facing problem while deploying my web application in Jboss 7.1.1 final. while deploying it gives me many warnings like below:

But ultimately the war was deployed and I was able to open the url in Jboss 7.1.1 final. but when I am trying to login to the application it gives me following error.

The same projects runs very fine in Tomcat 7.

Code Snippet:

@Action(TNIBeans.AUTHORIZATION_ACTION)
@Scope(TNIBeans.BEAN_SCOPE)
public class AuthorizationAction extends ActionSupport implements SessionAware,ServletRequestAware {

    private InputStream inputStream;
    /**
     * Logger for this class
     */
    private static final Logger logger = Logger
            .getLogger(AuthorizationAction.class);
    @Autowired
    private XStream xstream;
    
    public void logException(String message) {
        logger.error(message);
    }

    public void log(String msg) {
        logger.info(msg);
    }
    
    HttpServletRequest request = null;

    @Autowired
    @Qualifier(TNIBeans.EMPLOYEE_SERVICE_IMPL)
    private EmployeeService employeeServiceImpl;
    @Autowired
    @Qualifier(TNIBeans.CODE_SERVICE_IMPL)
    private CodeMasterService codeMasterService;
    
    Map<String,Map<String,String>> codeMaster = null;
    private String strResult = null;

    private static final long serialVersionUID = -8517227229292215672L;

    private Map<String, Object> session = null;
    private Employee emp = null;
    
    private String userName;
    private String password;
    private String roles;
    private String responseMsg;

    public String login () throws Exception {
        log("Entered login");
        if (logger.isDebugEnabled()) {
            logger.debug("execute() - start.....");
        }
        try {
            log("Authentication Started For User : "+userName);
        //  employeeServiceImpl.authenticate(userName, password);
            inputStream = new ByteArrayInputStream("success".getBytes("UTF-8"));
            log("Authentication Result : success");
            log("Initiating authorisation : ");  // This is printed in Console output if u observe (ie, till here the code                                  executed properly)

    // It couldn't create instance of "employeeServiceImpl" interface defined above..... 

            emp = employeeServiceImpl.authorize(userName);

Another code snippet of authorize function:

@Override
    public Employee authorize(String signum) throws BusinessException {
        System.out.println("Hi Tapo..."+signum); // this is not printed in console output if u observe (ie, controller doesn't                                  enter authorize function) 
        logger.info("authorize : "+signum);
        Employee emp = null;
        try{
            emp = findRoles(signum);
            if (WebConstants.adminSignum.equalsIgnoreCase(signum)) {
                emp.setSignum(signum);
                emp.setName("System Administrator");
                emp.setRoles(Role.LnCD_ADMIN);
                emp.setRoles(Role.LnCD_DELEGATE);
                emp.setRoles(Role.SYS_ADMIN);
            }
            return emp;
        }catch(BusinessException e){
            throw new BusinessException(e.getMessage());
        }catch(Exception e){
            throw new BusinessException(e.getMessage());
        }
    }

According to your console output that is relevant to the jboss server.log file that is in your deployment folder you've got java.lang.NullPointerException in the method login of the AuthorizationAction. And the exception occured right in the statement

emp = employeeServiceImpl.authorize(userName);

That is employeeServiceImpl is null. If it's not null then we've seen "Hi Tapo..." in the logs. Nothing similar happened.

Then the employeeServiceImpl is a property that initialized via Spring application context. Even not you posted the aplicationContext.xml here I assume there's bean definition in it. Then it should be injected, again assume that this works too, as for you said that it's well running at Tomcat server.

Hence this could only happen if the bean creation failed. This is exactly the case where NullPointerException you shouldn't prevent.

For that moment we only know that employeeService bean failed. We don't have the sources. You didn't posted it. Then we required additional exceptions from the log file to find the cause why the bean is not created. Didn't get it too.

So, the only way to find out to deploy the working app in Tomcat 7 on JBoss 7. And what happened, is some integrated frameworks become behave slightly different as expected. And they became load additional libraries that is not used under Tomcat. This is because the features of JBoss that is not available in the Tomcat. Finally I found that my resources stopped loading because JBoss returns URLs with vsf protocol. Even my application understands vsfzip protocol I needed to add those protocol to make it working.

Those warnings are only available during devMode(=true), if you don't use the Convention plugin, everything should be ok.

The proper support for JBoss 7 was added as from version 2.3.1 of Struts 2.
