i currently hang up in the Spring and JSF Integration. I think i misconfigured something and i can not see what exactly. I get a NULL Pointer Exception because of the Service Tier is not going to be loaded by the JSF Bean. My configuration is the following:

I'm happy for every fast clue :) Because i got no idea anymore
With org.springframework.web.jsf.el.SpringBeanFacesELResolver your class needs to be a
simple Spring component. Remove #ManagedBean and add #Component annotations.
You've created another instance of MitarbeiterBean managed by JSF via #ManagedBean annotation and it is not the same bean that is managed by Spring so the serviceMitarbeiter field is not injected. Just forget about JSF managed beans and use Spring components in JSF.
Also replace javax.faces.bean sope annotations with Spring #Scope.
e.g. #RequestScoped -> #Scope("request")

My problem is quite similar to this one (How can I do Spring Security authentication from within a JSF form), but I've tried that solution and the problem still occurs.

When I try to login with a valid user, it sends me to failLogin.xhtml
My DataBase: https://gyazo.com/3997921c1c9bc2787a25c9b0ff904f4b
What's my mistake?
Any help please?
The problem was that the passwords in the DB were not well encrypted, I tried to encrypt them with another website and I went all.
Please can you help me with this exception ? I looked in forums but I didn't find any solution.
I could not find the reason of the nullPointer !
I am working on spring, hibernate and jsf. I could neither insert the bean into database nor get the lines and print them into a dataTable.

I am beginner in spring3 so i am creating a simple login application. In my loginController i am getting "java.lang.ClassCastException: org.springframework.web.bind.support.SimpleSessionStatus cannot be cast to com.forms.LoginForm" on the following line

Please help.
Thanks,

You cannot use Object type to bind your form, use its type instead decoreated with #ModelAttribute1
#RequestMapping("/LoginAction")
public ModelAndView onSubmit(#ModelAttribute("loginForm") LoginForm command) {
Also I saw you're trying to create a new application context inside the controller which seem unecessary, use dependency injection / autowiring instead to your controller class
I searched some examples but i couldn't found any example. What I must do in loginController.login() method. How can I pass username and password text to spring-security?
Spring-security.xml

</p:panelGrid>
<p:commandButton value="Login" actionListener="#{loginController.login()}"/>
</p:outputPanel>
</h:form>
</h:body>
Personally I use this way to set Spring-Security context values:
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
//....
//In your login method:
List<Authority> auths = new ArrayList<Authority>();
auths.add(new Authority("ROLE_USER")); //Role here, like "admin"
Authentication authentication = new UsernamePasswordAuthenticationToken(token, null, auths);
SecurityContextHolder.getContext().setAuthentication(authentication);
The Authority class is as follow:
import org.springframework.security.core.GrantedAuthority;
public class Authority implements GrantedAuthority{
private static final long serialVersionUID = 9170140593525051237L;
private String authority;
public Authority(String authority) {
super();
this.authority = authority;
}
#Override
public String getAuthority() {
return authority;
}
#Override
public String toString() {
return "Authority [authority=" + authority + "]";
}
}
I hope this helps
You can you Pricipal object to get the user details as shown below.
login(Principal principal){
if (principal instanceof UsernamePasswordAuthenticationToken) {
UsernamePasswordAuthenticationToken userDetails = (UsernamePasswordAuthenticationToken) principal;
userDetails.getName();
}
i created a form and on post i want to save those values to the database and show the saved values on the page.
i am new to spring mvc and hence i am not understanding where i am going wrong.

After i click the save button i get the above mentioned error.Please help me resolve this.
Seems to be a problem in your form. At least, the inputs must be given the name attributes:
<form method="post" action="<c:url value='/customer/'/>">
Cust_Id :
<input type="text" name="custid">
<br>
Name :
<input type="text" name="name">
<br>
Age :
<input type="text" name="age">
<input type="submit" value="Save">
</form>
But since you are using Spring, it is preferable to use the Spring forms (and spring url's also):
<spring:url var="customer" value="/customer"/>
<form:form action="${customer}" method="post" modelAttribute="customer">
<form:label path="custid">Id:</form:label>
<form:input path="custId"/> <br>
<form:label path="name">Name:</form:label>
<form:input path="name"/> <br>
<form:label path="age">Age:</form:label>
<form:input path="age"/> <br>
<input type="submit" value="Save"/>
</form:form>
Edit
And you should initialize dao!
#Autowired
private CustomerDao dao;
The attribute of your model has annotated with #ModelAttribute to be nulleable. This is so that when an exception occurs in times of bind there is something to return.
Note the difference between the model attribute and the model attribute parameter.
An exception during bind and validation times could be passing text in an integer field.
Exception:
org.springframework.web.util.NestedServletException:
Request processing failed; nested exception is java.lang.NullPointerException:
Parameter specified as non-null is null: method yourMethod, parameter yourParam
In Kotlin
Going from student: Student to student: Student? exception is avoided.
#RequestMapping("/processFormRegister")
fun processFormRegister(
#Valid #ModelAttribute("firstStudent") student: Student?,
validationResult: BindingResult
): String {
return if (validationResult.hasErrors()) {
"StudentFormRegister"
} else {
"ResultFormRegister"
}
}
And also to see the exception transformed into a validation you could use #Valid and Binding Result of Hibernate Validator obtaining:
failed to convert value of type java.lang.string[] to required type java.lang.integer; nested exception is java.lang.numberformatexception: for input string: "a"
