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

[Dave Isenhower <disenhower@xxxxxxxxxxxxxxxxxxxxxxx>]

I got it working on another machine.  Still not sure why it was failing.  Thanks for all your help!

Dave, It looks right.

 

I created a local test case with your class (I stubbed out the ones I didn't have) and your xml and it worked...

 

Is it possible that you are getting another error prior to the one that you mentioned? Also can you try and simplify your test case to see if something is masking the problem?

Here it is:

public class UniformWebRequestRouter implements WebRequestRouter
{
    protected UniformMessage mailMessage;
    protected UniformMessageSender uniformMessageSender;
   
    // list of acceptable urls to get templates from
    protected List templateLocation;
    protected String templateName;
   
    public UniformWebRequestRouter()
    {
    }

    public UniformMessage getMailMessage()
    {
        return mailMessage;
    }
    public void setMailMessage( UniformMessage mailMessage )
    {
        this.mailMessage = mailMessage;
    }

    public String getTemplateName()
    {
        return templateName;
    }
    public void setTemplateName( String templateName )
    {
        this.templateName = templateName;
    }
    public List getTemplateLocation()
    {
        return templateLocation;
    }

            UniformMessageSender uniformMessageSender) {
        this.uniformMessageSender = uniformMessageSender;
    }
}

Dave,

 

Can you send a copy of the webrequest.router.uniform.UniformWebRequestRouter class?

 

Thanks,

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>
    </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!
