Error creating bean with name PropertyName: No property found

Question

I create beens with Spring in ApplicationContext.xml like below:

<bean id="myClass" class="com.classes.MyClass">
 <property name="Url" value="https://localhost"&gt;&lt;/property&gt;
 <property name="Name" value="admin"></property>
 <property name="Password" value="admin"></property>
</bean>

package com.classes

public class MyClass {
    private String Url;
    private String Name;
    private String Password;
    public void setUrl(String url) {
        Url = url;
    }
    public String getUrl() {
        return Url;
    }
    public void setName(String name) {
        Name = name;
    }
    public String getName() {
        return Name;
    }
    public void setPassword(String password) {
        Password = password;
    }
    public String getPassword() {
        return Password;
    }
}

here is the factory, I wonder there is anything wrong with it

public class SpringFactory implements FlexFactory {
    private static final String SOURCE = "source";

    public void initialize(String id, ConfigMap configMap) {
    }

    public FactoryInstance createFactoryInstance(String id, ConfigMap properties) {
        SpringFactoryInstance instance = new SpringFactoryInstance(this, id, properties);
        instance.setSource(properties.getPropertyAsString(SOURCE, instance.getId()));
        return instance;
    } // end method createFactoryInstance()

    public Object lookup(FactoryInstance inst) {
        SpringFactoryInstance factoryInstance = (SpringFactoryInstance) inst;
        return factoryInstance.lookup();
    }

    static class SpringFactoryInstance extends FactoryInstance {
        SpringFactoryInstance(SpringFactory factory, String id, ConfigMap properties) {
            super(factory, id, properties);
        }

        public String toString() {
            return "SpringFactory instance for id=" + getId() + " source=" + getSource() + " scope=" +
                    getScope();
        }

        public Object lookup() {
            ApplicationContext appContext = WebApplicationContextUtils.getWebApplicationContext(flex.messaging.FlexContext.getServletConfig().getServletContext());

            String beanName = getSource();
            try {
                return appContext.getBean(beanName);
            } catch (NoSuchBeanDefinitionException nexc) {
                ServiceException e = new ServiceException();
                String msg = "Spring service named '" + beanName
                        + "' does not exist.";
                e.setMessage(msg);
                e.setRootCause(nexc);
                e.setDetails(msg);
                e.setCode("Server.Processing");

                throw e;
            } catch (BeansException bexc) {
                ServiceException e = new ServiceException();
                String msg = "Unable to create Spring service named '"
                        + beanName + "' ";
                e.setMessage(msg);
                e.setRootCause(bexc);
                e.setDetails(msg);
                e.setCode("Server.Processing");
                throw e;
            }
        }
    }
}

But it threw Error creating bean with name Password: No property found

It only happens with the 3rd String property, if I only set 2 String property, and let the 3rd refer to another bean. It works. But everytime I put 3rd property there. It fails. Is there any restriction or configuration. Don't tell me that I made any typo or wrong naming, it wouldn't wrong because I checked very carefully.
