Neither BindingResult nor plain target object for bean name ... problem

[Pawel]

Hi,

I have a strange problem with my Spring 2.5 and Tomcat 5.5
application.

I have a form which looks like this:


<form:form method="post" commandName="loginCommand">
<form:errors path="*" cssClass="errorBox" />
<div id="login" class="lightBorder label">
<div id="header" class="lightBorder">Login</div>
user <form:input path="user"/> <form:errors path="user"/>
password <form:password path="password"/> <form:errors
path="password"/>

<div id="submit"><input type="Submit" name="submit" class="submit"
value=""></div>
</div>
</form:form>



My controller of this form looks like this:

public class LoginFormController extends SimpleFormController {
private Logger log = Logger.getLogger(LoginFormController.class);

public LoginFormController() {
log.debug("Constructor");
setCommandName("loginCommand");
setCommandClass(LoginCommand.class);
}

protected ModelAndView onSubmit(HttpServletRequest request,
HttpServletResponse response,
Object command, BindException errors) throws ServletException {
....
}
}

My command class looks like this:

public class LoginCommand {
private String user;
private String password;

public String getUser() {
return user;
}
public void setUser(String user) {
this.user = user;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}


My dispatcher-servlet.xml's appropriate fragment looks like this:

...
<bean id="loginFormController"
class="org.dyndns.orzekanie.controller.LoginFormController">
<property name="successView" value="/navigation/logon"/>
<property name="formView" value="/authexclude/index"/>
<property name="validator" ref="loginValidator"/>
</bean>
...

<bean id="urlMapping"
class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<value>
/jsp/authexclude/index.html=loginFormController
</value>
</property>
<property name="order" value="0"/>
</bean>
....





When I'm trying to run my application and display my form I get:

2008-01-22 16:59:44,578 610 DEBUG

Everything looks allright for me - I find this exception very strange.
Could anyone give me some advice?
Thanks,
Pawel

Hello,
I am having the same issue. I have followed the examples in the
online documentation exactly.
Have you resolved this?
Thanks
