i think the problem is in the Hibernate Helper but i can't figured where
any advise?
import java.util.Properties;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;
public class HibernateHelper {
private static SessionFactory sessionFactory;
static{
try {
Configuration configuration = new Configuration();
Properties properties = configuration.getProperties();
ServiceRegistry serviceRegistry = new ServiceRegistryBuilder()
.applySettings(properties)
.buildServiceRegistry();
sessionFactory = configuration.buildSessionFactory(serviceRegistry);
} catch (Throwable e) {
throw new ExceptionInInitializerError(e);
}
}
public static final SessionFactory getSessionFactory() {
return sessionFactory;
}
public static final void shutdown(){
getSessionFactory().close();
}
}
I had same kind of problem when using following combination.
Struts 2.5 jar
Hibernate 4.3.5.Final
MySQL connector 6.0.3
Java 7
On changing mysql-connector-java to lower version 5.1.10, it solved. Please check your mySQL connector compatibility with your Spring and Hibernate jars. You can see your spring jars configuration as well.

The class app required is com.junta.model.User
I tried change mapping class but it didn't resolve my issue.
I have read about CLASSPATH, may be I need change smth in setup?
I got a webapp. It works fine on iosx. But if I import the project(mavenproject) into my virtualbox to windows 10(clone with git and import into eclipse with mavenproject). If I want to upload something to the server I get an error."The requested resource is not available." To see the uploadpage I got the following controller:
#RequestMapping(value = "/erstellen", method = RequestMethod.GET)
public String zeigErstellenForm() {
System.out.println("im here");
return "dateien_upload_erstellen";
}
Its possible to see the uploadpage so I guess this function is called but it doesn't print "im here". I can't understand whats going on.

There are no errors in the project. I clean everything updated maven etc.
You can not display a sysout message inside a JSP!
In the WEB-INF/jsp directory of your webapp, create a file index.jsp and write inside these JSP, your helloWorld message.
It will work unless you have missed something else.
Or if you want to use the Model, something like below inside your controller :
ModelAndView mav = new ModelAndView();
mav.addObject("message", "hello world");
return mav;
For your nullpointer exception, I will try remote debugging with your eclipse platform, and make some breakpoints inside the lines :

I am creating basic HelloWorld application in Spring MVC.
But it throws me error.

How can I solve error?
I am trying to simply get my default error page to display when an error occurs. I have tried every configuration I can think of, but I just can't get it to work. When I navigate directly to the error page it works, but errors will not direct there (in the native Eclipse browser or any mainstream browser).
There are no errors in the DD.
Here is how I currently have the DD:
<?xml version="1.0" encoding="UTF-8"?>

</error-page>
<error-page>
<exception-type>java.io.IOException</exception-type>
<location>/MyApp/errorPage.jsp</location>
</error-page>
</web-app>
(I'm specifying 429 because the API I am working with has been throwing those to me recently)
Here is the error page:
<%# page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1" isErrorPage="true" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<title>You blew it</title>
</head>
<body>
<p>You caused a ${pageContext.exception} exception</p>
</body>
</html>
If it helps, here is the 429 error, and subsequent IOException error log I am getting (not looking to solve this here, just in case it helps).

I am new to Spring. I am trying to run a self-learning project called library, using Spring web flow on Tomcat. As the IDE I use Eclipse Indigo.
My project's WebContent folder structure is as following:
WebContent
pages
welcome
- introduction.jsp
- menu.jsp
- welcome.jsp
- welcome.xml
WEB-INF
- library-service.xml
- library-servlet.xml
- library-webflow.xml
- web.xml
lib
- commons-logging.jar
- jstl.jar
- ognl-2.6.9.jar
- org.springframework.binding-2.0.9.RELEASE.jar
- org.springframework.js-2.0.9.RELEASE.jar
- org.springframework.webflow-2.0.9.RELEASE.jar
- spring.jar
- spring-webmvc.jar
- standard.jar
As the content web.xml, it is as following:
<display-name>library</display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/library-service.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>library</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>library</servlet-name>
<url-pattern>/pages/*</url-pattern>
</servlet-mapping>
The content of library-servlet.xml is as following:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
<import resource="library-webflow.xml" />
</beans>
I have used the library-service.xml to declare to beans from service layers. Its content is as following:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
<bean name="libraryService"
class="com.library.service.LibraryService" />
</beans>
As the content of welcome.jsp page, it is as following:
<html>
<head>
<title>Welcome</title>
</head>
<body>
<h2>Welcome!</h2>
Next
Skip
</body>
</html>
As the content of welcome.xml is:
<flow xmlns="http://www.springframework.org/schema/webflow"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/webflow
http://www.springframework.org/schema/webflow/spring-webflow-2.0.xsd">
<view-state id="welcome">
<transition on="next" to="introduction" />
<transition on="skip" to="menu" />
</view-state>
<view-state id="introduction">
<transition on="next" to="menu" />
</view-state>
<view-state id="menu" />
</flow>
My problem is that when I runned welcome.jsp, I got the following nested error in Tomcat. I am using Tomcat 6.0.35.

Am I doing something wrong?
Try adding the webflow XML to the web.xml:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/library-service.xml, /WEB-INF/library-webflow.xml</param-value>
</context-param>
