Cannot upload my Web Applicartion in Jboss7 EAP7 EAP

I must to test this web app, but when I try to deploy on JBoss 7 EAP this is the error, maybe I forgot something?
This is the exception that the application throws:
Cannot upload deployment: {"WFLYCTL0080: Failed services" => {"jboss.deployment.unit.\"WebAppGuestbooks.war\".INSTALL" =>

This is the path of Project

Your persistence.xml file is in the wrong place. The JPA uses a convention to find your persistence.xml so you have put the file in the right place.
According to the Oracle docs:
The JAR file or directory whose META-INF directory contains persistence.xml is called the root of the persistence unit.
If you package the persistent unit as a set of classes in an EJB JAR file, persistence.xml should be put in the EJB JAR’s META-INF directory.
If you package the persistence unit as a set of classes in a WAR file, persistence.xml should be located in the WAR file’s WEB-INF/classes/META-INF directory.
In your case when the persistence.xml file is in src/META-INF/ (if you use MAVEN the path is src/resources/META-INF) its going to be packaged in your war in the WEB-INF/classes/META-INF folder, funcioning as the root of the persistence unit.

you have wrong file name with typo hibernate.cgf.xml should be hibernate.cfg.xml

You have given wrong name hibernate.cgf.xml in getInfo method. That is why you are facing issue

I am not able to get the output. 404 error comes. Is there any problem with the jar?

I got it resolved! I downloaded from the sourceforge DTD and added it to my root directory which is SRC folder.
And, edited the hibernate.cfg.xml to be as below:
<!DOCTYPE hibernate-configuration SYSTEM
"hibernate-configuration-3.0.dtd">
by this way the application doesnt have to hit the URL but it points and finds the DTD in the src folder. this you can do when you are using your system online.
IT worked for me after hell a lot of researches!!

openSession(), getCurrentSession(), beginTransaction(), lazy load

I have a simple java web application that receive some information from database and display that information in web browser. Hibernate is used to interact with database in servlets and jsp files. All work as I want, but I don't understand some things.
Database is simple - 2 tables: Question and Answer. Relationship between tables is one-to-many: one Question can have many Answers.
This is code of java classes Question and Answer:
Question.java
package app;
import java.util.Set;
public class Question {
Long id = null;
String text = "";
Set<Answer> answers = null;
public Question() {
}
public void setId(Long id) {
this.id = id;
}
public void setText(String text) {
this.text = text;
}
public void setAnswers(Set<Answer> answers) {
this.answers = answers;
}
public Long getId() {
return id;
}
public String getText() {
return text;
}
public Set<Answer> getAnswers() {
return answers;
}
}
Answer.java
package app;
public class Answer {
Long id = null;
String text = "";
Question question = null;
public Answer() {
}
public void setId(Long id) {
this.id = id;
}
public void setText(String text) {
this.text = text;
}
public void setQuestion(Question question) {
this.question = question;
}
public Long getId() {
return id;
}
public String getText() {
return text;
}
public Question getQuestion() {
return question;
}
}
And this is configuration of Hibernate:
hibernate.cfg.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

</hibernate-mapping>
So in Question there is a collection of Answers. Because of this there would be a lazy load of Answers. I want to use Hibernate objects in my jsp files, so I use this technique: the filter is used to create a session, and this session is used in both servlet and coresponding jsp file.
This is code of that my filter:
HibernateFilter.java
package app;
import java.io.IOException;
import javax.servlet.*;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class HibernateFilter implements Filter {
private SessionFactory sessionFactory;
public void doFilter(ServletRequest request,
ServletResponse response,
FilterChain chain)
throws IOException, ServletException {
try {
sessionFactory.getCurrentSession().beginTransaction();
chain.doFilter(request, response);
sessionFactory.getCurrentSession().getTransaction().commit();
} catch (Exception ex) {
sessionFactory.getCurrentSession().getTransaction().rollback();
ex.printStackTrace();
}
}
public void init(FilterConfig filterConfig) throws ServletException {
sessionFactory = new Configuration().configure().buildSessionFactory();
}
public void destroy() {
}
}
There are two servlets and two coresponding jsp files in my application - first ones display question with ID = 1, second ones display all questions. This is code of this servlets, coresponding jsp files and configuration of tomcat:
GetOneQuestion.java
package app;
import java.io.IOException;
import javax.servlet.*;
import javax.servlet.http.*;
import org.hibernate.Session;
import org.hibernate.cfg.Configuration;
public class GetOneQuestion extends HttpServlet {
#Override
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
try {
Session session = new Configuration().configure()
.buildSessionFactory().getCurrentSession();
session.beginTransaction();
Question question = (Question)session.load(Question.class, 1L);
//session.getTransaction().commit();
request.setAttribute("oneQuestion", question);
} catch (Exception ex) {
ex.printStackTrace();
request.setAttribute("oneQuestion", null);
}
RequestDispatcher view = request.getRequestDispatcher("/oneQuestion.jsp");
view.forward(request, response);
}
}

session.beginTransaction();
Query query = session.createQuery("from Question");
List all = query.list();
request.setAttribute("allQuestion", all);
} catch (Exception ex) {
ex.printStackTrace();
request.setAttribute("allQuestion", null);
}
RequestDispatcher view = request.getRequestDispatcher("/allQuestion.jsp");

}
}

List all = (List)request.getAttribute("allQuestion");
for (Object object : all) {
Question question = (Question)object;
out.print("<br>Question " + question.getId());

Question
1) Why I need to call "session.beginTransaction()" method in servlets even if I already call "session.beginTransaction()" in filter? If I call one servler from another I also have to call this method in second servlet? Or I have to call this method before every interaction with database?
2) I don't call "sessionFactory.getCurrentSession().openSession()" or "sessionFactory.getCurrentSession().getCurrentSession()" in filter but I call "sessionFactory.getCurrentSession().getCurrentSession()" in servlet and still obtain session which seem to be create in filter. How this can be?
3) If I uncomment line "session.getTransaction().commit();" in GetOneQuestion class from jsp file I receive LazyInitializationException: "could not initialize proxy - no Session" even if there is no lazy load in this jsp file because I don't use any Answer object there. What cause this Exception? Session must be open for any interaction with Hibernate object even if there is no lazy load?

You need to configure a session factory one time (!) on the application startup, not in an every servlet.
You need to close session in the filter after a transaction commit.
You don't need create a transaction in the servlet (or you don't need create a transaction in the filter).
You can store a session factory in the static field of the application initializer class and get current session from it in servlets.
About your questions
Because you do a mistake. You create a new session factory in the servlet.
You obtain a new session (because of your incorrect session factory creation). In the normal situation getCurrentSession() return a session bound to the current thread by ThreadLocal(Not always, It depends of configuration).
You have LazyInitializationException with question.getAnswers().

NPE after upgrading JAX-WS version 2.2.1 to 2.2.8

The application was using JAX-WS version 2.2.1 where I found issue in dealing with CustomException. Unable to generate the classes due to com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions. So I changed the version of JAX WS to JAX-WS 2.2.8, the above issue got solved(the classes for CustomExceptions got created). But now I am getting the following error while trying to consume the service:

I could avoid the NPE by modifying my Webservice endpoint class but not so sure whether the following solution is best or not, but it works for me:
#MTOM
#WebService(name = "sampleService")
#SOAPBinding(style = SOAPBinding.Style.DOCUMENT, use = SOAPBinding.Use.LITERAL, parameterStyle=ParameterStyle.WRAPPED)
public class SampleServiceEndpoint extends SpringBeanAutowiringSupport {
#Autowired
LookupService lookupService;
#Autowired
PersistenceService persistenceService;
#WebMethod(exclude=true)
private void initLookupService(){
if(lookupService == null)
processInjectionBasedOnCurrentContext(this);
}
#WebMethod(exclude=true)
private void initPersistenceService(){
if(persistenceService == null)
processInjectionBasedOnCurrentContext(this);
}
#WebMethod
public List<Items> getItems() {
initLookupService();
return lookupService.getItems();
}
#WebMethod
public long updateItem(#WebParam(name = "item") Item item) throws ConcurrencyException{
initPersistenceService()
return persistenceService.updateItem(item);
}
#XmlMimeType("application/octet-stream")
#WebMethod
public DataHandler downloadFaxFile(String filename){
return new DataHandler(new FileDataSource(filename));
}
}
