Try using the DiscoveryNavigator instead of the default Vaadin navigator.
Then add the views using addBeanView

@Alexander DM

I added my export from eclipse.

Alexander thanks for your time really help me up, I finally find my problem, it was the param value of my beanName in the web.xml. It was like this

<init-param>
            <param-name>beanName</param-name>
            <param-value>sv.com.vaadin.MainUI</param-value>
            <load-on-startup>5</load-on-startup>
</init-param>

then I changed to

<init-param>
            <param-name>beanName</param-name>
            <param-value>mainUI</param-value>
            <load-on-startup>0</load-on-startup>
        </init-param>

and it’s works.`

addionaly also added the default target url at this line in the security.xml

<form-login login-page="/login/" always-use-default-target="true" default-target-url="/" />

Thanks.

Hello, I have a problem with the spring security integration with vaadin, the login page works fine, I enter the credentials and got forwarded to the MainView, in this view I can see the authoritys, then when I click the link “ROLE_ADMIN View (throw exception, if user doesn’t have access)” I got the next error and lose the user and his roles, and dont do the validation to the view, ignore the @Secured annotation.

Is Spring Java Configuration instead of XML configuration supported?

[Chris67 (Chris Steinmeyer)]

If you mean the annotation-based-configuration then it is possible. But you still need a small application context where you configure spring to use annotations.

applicationContext.xml[code]

<?xml version="1.0" encoding="UTF-8"?>

<context:annotation-config/>
<context:component-scan base-package="de.test"/>

[/code]

simple bean[code]
package de.test;

@Component
@Scope(“session”)
public class TestBean {
// some code
}
[/code]

simple vaadinview[code]
package de.test;

@Component
@Scope(“session”)
@VaadinView(value=“test”)
public class TestView extends CustomComponent implements View{
@Autowired
private TestBean bean;

@Override
public void enter(ViewChangeEvent event) {
	// some code
}

}
[/code]

[Andreas43 (Andreas Kessler)]

I mean annotation based config instead of an applicationContext.xml, or do I need always an XML?

package com.foo.bar.conf;

@Configuration
@Profile("test")
public class TestProfileConfig {
 
    @Bean
    public Person employee() { 
        return new Person("John", "Smith", 55);
    }
}

Hello, I have a problem when create framework project with maven, vaadin version 7.1.4, adds on spring integration and hibernate3. I cannot config it work with MVC. I need simple project for it.
Please help me.

[Chris67 (Chris Steinmeyer)]

@Andreas Kessler

Yes this is possible without an xml.

Configuration classes:

package de.test;

// Load this property file
@PropertySource("classpath:database.properties")
// Spring context configuration
@Configuration
public class DataConfig {
	@Autowired
	Environment env;
	
	// For classes which don't have a "@Component" annotation
	@Bean
	public DataSource dataSource(){
		BasicDataSource dataSource = new BasicDataSource();
		dataSource.setUrl(env.getProperty("jdbc.url"));
		dataSource.setUsername(env.getProperty("jdbc.username"));
		dataSource.setPassword(env.getProperty("jdbc.password"));
		return dataSource;
	}
	
	@Bean
	public PlatformTransactionManager transactionManager(){
		return new DataSourceTransactionManager(dataSource());
	}
}

package de.test;

@EnableTransactionManagement
// Import the other configuration
@Import(DataConfig.class)
// This does the same as
// <context:annotation-config/>
// <context:component-scan base-package="de.test"/>
@ComponentScan("de.test")
@Configuration
public class AppConfig {
	@Autowired
	DataConfig dataConfig;
}

Hi!

I have my Vaadin 7 web project and my widgetset in separate locations, using maven 3.
My widgetset project pom contains other Vaadin addons and is working fine since before I added spring-vaadin-integration.
My Vaadin web project pom contains the spring-vaadin-integration addon.

When I run the application I get this message:

INFO: Requested resource 
[/VAADIN/widgetsets/com.example.application.common.widgetset.AppWidgetSet/com.example.application.common.widgetset.AppWidgetSet.nocache.js] 
not found from filesystem or through class loader. Add widgetset and/or theme JAR to your classpath or add files to WebContent/VAADIN folder.

… and this error message when I hit refresh in my browser:

Failed to load the widgetset: ./VAADIN/widgetsets/com.example.application.common.widgetset.AppWidgetSet/com.example.application.common.widgetset.AppWidgetSet.nocache.js?1380183315479

When I unpack the widgetset.jar the widgetset and the “missing” file are at the correct location.

My web.xml contains the correct path too…

Is there anything else wrong with my web.xml?

[Marius14 (Marius Reinwald)]

Try to run maven clean and then recompile your widgetset and application.

[Roger34 (Roger Stenman)]

Hi Marius! I have tried cleaning and recompiling, and cleaning everything in Tomcat. Unfortunately I end up with the same error.

[Roger34 (Roger Stenman)]

Perhaps this is not related to spring-vaadin-integration. I just had a look in my Tomcat Deployment directory and found that the application-common-widgetset-0.0.11-SNAPSHOT.jar in there was only 6kb, containing only the /com and /META-INF directories.

I went to my workspace/…/lib folder and copied the application-common-widgetset-0.0.11-20130926.124257-7.jar in there (>20Mb) to the Tomcat Deployment directory and it worked.

It seems like I have some problems with my widgetset pom-structure.

Hi,
In apache-shiro example you’ve used seperate login page. Have you tried to implement login page in vaadin? I used: <property name="loginUrl" value="/#!login"/> <property name="successUrl" value="/"/> in ShiroFilterFactoryBean but it doesn’t work. /#!login is a view in vaadin. Everything compiles, but when I enter the page, I get something like ‘bad redirection’ in all browsers.

That’s exactly what I used the UI provider for. I made LoginUI and MainUI and the provider displays the UI based to the path in the request - /login loads the LoginUI, everything else is MainUI. Works out quite nicely.

AT

I have a same problem if I want to implement a login page .
Can u help me. If UiProvider is solution, how it is configured to launch login page (#!loginView)

Thx

[Pat5 (Pat Novak)]

I’ve downloaded Vaadin sample projects from xpoft’s github and they work fine, except the spring-security example. Whenever I type the login and password (did not change anything, so default user/user or admin/admin) it just gives me 404 error. Anyone know how to fix it?

[Fabrizio18 (Fabrizio Gianneschi)]

Hi, I’m trying to use your plugin under Vaadin 7.0.1 and Spring 3.2.2.

I can’t get Spring to see the main UI bean registered with the “beanName” in the web.xml, even if I’ve annotated it correctly (@Component and @Scope).
The applicationContext.xml has both the context:annotation-config and context:component-scan tags.

It seems that Spring isn’t looking at the annotations: NoSuchBeanDefinitionException
Could you help me?

[Chris130 (Chris Steinmeyer)]

Can you post your web.xml?

It seems that you define the wrong name for your UI.

[code]
@Component
public class
MainUI
… {
…
}

<…>

beanName

mainUI


</…>
[/code]In this example it is important that the bean name is “mainUI” and not e.g. “mainUi”. Be sure that this is not the problem. Otherwise post your web.xml.

[Fabrizio18 (Fabrizio Gianneschi)]

Thanks, it was exactly a wrong name problem in the web.xml.
My beanName’s param-value had its first letter capitalized, and this doesn’t work.

[erg144 (Ed Ross)]

I have been having a very difficult time trying to use the spring integration. Basically, the main UI is working and wired up with spring, However, I can not get any of the navigational views working with Spring. I have tried the normal navigation and the DiscoveryNavigator without much luck. The classes are loaded, but not controlled by spring.

@Component
@Scope(“prototype”)
@VaadinView(LoginViewComponent.NAME)
public class LoginViewComponent extends CustomComponent implements View,
Button.ClickListener {

@Autowired
private transient ApplicationContext applicationContext;

@Transient
@PersistenceContext(name="model")
EntityManager entityManager;

I expected the applicationContext and entityManager to have been populated but both are null.

any help?

thx

Vaadin 7.1.0 and SpringVaadinIntegration 2.0.2
@Component
@Scope(value = “session” , proxyMode = ScopedProxyMode.TARGET_CLASS)
MyCOmponent extennds AbstractComponent
on detach() doesn’t clears connectorId

UI has Request Scope

So, on reinitializng UI throws RuntimeException: A connector with id 9 is already registered!

Repoducing: using SpringSecurity.

1. log in
2. log out (close session)
3. log in

The same problem found in article: http://ttlnews.blogspot.com/2013/07/vaadin-error-connector-with-id-7-is.html

[Chris130 (Chris Steinmeyer)]

@Ed Ross

It can be possible that Spring didn’t find your class. Is your view class in a package which is scanned by Spring? Otherwise Spring cannot find your view class and autowiring isn’t working.
