Re: [cinjug-users] Bean Property not writable in Spring

[Dave Isenhower <disenhower@xxxxxxxxxxxxxxxxxxxxxxx>]

Thanks, that got me over one hurdle, but now I'm getting the same exception on a property that is not capitalized:

org.springframework.beans.NotWritablePropertyException: Invalid property 'uniformMessageSender' of bean class [webrequest.router.uniform.UniformWebRequestRouter]: Bean property 'uniformMessageSender' is not writable or has an invalid setter method: Does the parameter type of the setter match the return type of the getter?

    <bean id="myRouter" class="webrequest.router.uniform.UniformWebRequestRouter">
        <property name="uniformMessageSender">
            <ref bean="myMessageSender" />
        </property>
    </bean>

    <bean id="myMessageSender" class="webrequest.router.uniform.UniformMessageSender">
        <property name="defaultUniformMessage">
            <ref bean="defaultMessage" />
        </property>
        <property name="javaMailSender">
            <ref bean="javaSender" />
        </property>
    </bean>

    <bean id="defaultMessage" class="webrequest.router.uniform.UniformMessage">
        <property name="messageTemplate">
            <value>/etc/mail/uniformMessage.vm</value>
        </property>
        <property name="velocityEngine">
            <ref bean="velocityEngine" />
        </property>
    </bean>

Dave,

 

I might be mistaken, but I think the property you are trying to set should be 'messageTemplate' instead of 'MessageTemplate' (note the lowercase m).

 

Sorry if it's not that, and I have overlooked something...

Subject: [cinjug-users] Bean Property not writable in Spring

I'm having trouble wiring up a bean with Spring 1.1.4.  Has anyone run into a similar problem where you are unable to set a property because the property is "not writable?"  I here's the exception:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'defaultMessage' defined in ServletContext resource [/WEB-INF/UniformDispatcher-servlet.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'MessageTemplate' of bean class [webrequest.router.uniform.UniformMessage]: Bean property 'MessageTemplate' is not writable or has an invalid setter method: Does the parameter type of the setter match the return type of the getter?
    at org.springframework.beans.BeanWrapperImpl.setPropertyValue(BeanWrapperImpl.java:771)

Here is the relevant snippet of my UniformDispatcher-servlet.xml (note:  if I comment out the defaultMessage bean, the javaSender bean sets up OK):

    <bean id="defaultMessage" class="webrequest.router.uniform.UniformMessage">
        <property name="MessageTemplate">
            <value>/etc/mail/uniformMessage.vm</value>
        </property>
        <property name="VelocityEngine">
            <ref bean="velocityEngine" />
        </property>
    </bean>   

    <bean id="javaSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
        <property name="host">
            <value>mail.somewhere.com</value>
        </property>
    </bean>
   
   
    <bean id="velocityEngine" class="org.apache.velocity.app.VelocityEngine" init-method="init">
    </bean>

Finally, here is the code.

public class UniformMessage
{

    protected String messageTemplate = "";

    public UniformMessage()
    {
    }

...

    public String getMessageTemplate() {
        return messageTemplate;
    }
    public void setMessageTemplate(String messageTemplate) {
        this.messageTemplate = messageTemplate;
    }

}

Your help would be appreciated!
