org.springframework.beans.NotWritablePropertyException: Invalid property while sending email

Hello All,

I am a new to spring framework.

I want to send an email to user for alert purpose.

I have want to expose this as a cxf web service.

After creating classes from WSDL2Java plug in i have implemented necessary methods in my NotificationServiceImpl class.

Following is my XML configuration.

XML:
===

<bean class="com.pmc.ws.notificationservice.NotificationServiceImpl">
<property name="mailSender" ref="mailSender"/>
<property name="messageTemplate" ref="messageTemplate"/>
</bean>

<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
<property name="host" value="10.60.10.210"/>

<property name="username" value="Live.Server@abc.in"/>
<property name="password" value="abc123"/>
<property name="port" value="25"/>
<property name="javaMailProperties">
<value>
mail.smtp.auth=true
</value>
</property>
</bean>

<bean id="messageTemplate" class="org.springframework.mail.SimpleMailMessage" scope="prototype">
<property name="from" value="Live.Server@abc.in"/>
</bean>

Following is my NotificationServiceImpl class
=============================

/**

Any Help will be appreciated.

Thanks & Regards,

Are you sure you deployed the right class ?

Ya surely.....I have properly bundled it as the Service assembly and
I m using sericemix for deploying it....

Just in case, unbundle it and decompile the class file. (using jad or other decompilers). I can't see anything wrong with your sources.

Ohh k I got it solved...

In the NotificationServiceImpl Class i have changed the data type to the "mailSender" variable.

Earlier it was : private MailSender mailSender;

Now it is : private JavaMailSender mailSender;

And it started working...However interface JavaMailSender extends MailSender...so it must work...

I have also tried by keeping its data type of the JavaMailSenderImpl still it was showing same error.

But anyways...Thank you very much for all you response.

Appreciated.

And it started working...However interface JavaMailSender extends MailSender...so it must work...

Yes, I checked that too. The wiring worked on my environment (Spring 3.0.2). Which version of Spring are you using ?

Anyway, it's good that you found a way around this problem !

I guess we are using Spring 3.0.2 but i have observed one thing,

There are 3 jars available in my classpath...

1) spring-context-support-2.5.6.jar
2) spring-context-support-2.5.6.SEC01.jar
3) spring-support-2.0.8.jar

And all of this jar contains the JavaMailSenderImpl.class in it.

Do you think it might cause an issue of this?

Only one of them will be used, I don't think this should cause such a problem. Making a bit of clean up wouldn't hurt though

Ok Cool.

Anyways thanks for your reply.

I had the same problem, when you were telling about the changes in the code I came to the following idea (resolution).

My code was correct with the setter for injection. But I had two maven projects, project A and project B.
Project A was de application project and depended on Project B (a service).
When building project A it get the jar from my maven repository instead of building the dependent project B and using that jar, and while changing the code in project B and running in Eclipse went wel, running the same code from the command line would complain about the setter.
After doing mvn install on project B I was able to run the project A from command line successfully.

Hope this helps anyone who also had the same issue when working with multiple projects. (I know I should have made maven modules for these two dependent projects).

Hi ,

Am getting NotWritablePropertyException.

Configurations:

delivery.xml

<bean id="deliveryResponseService" class="com.telenor.cinclus.metermaid.delivery.impl.DeliveryResponseServiceImpl">
<property name="estimationService" ref="estimationManager"/>
<property name="missingReadingDate" value="${delivery.qualityx.missing.date}" />
<property name="powerDownSeconds" value="10" />
</bean>

Below is the code.

public class DeliveryResponseServiceImpl implements DeliveryResponseService {

/** The logger. */
private Log logger = LogFactory.getLog(getClass());

/** Service for estimating missing values. */
private EstimationService estimationService;

private Date missingReadingDate;

private int powerDownSeconds;

/**
* Sets the estimation service.
*
* @param estimationService
* the new estimation service
*/
public void setEstimationService(final EstimationService estimationService) {
this.estimationService = estimationService;
}

public void setMissingReadingDate(String missingReadingDate) {
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MMM-dd HH:mm:ss.SSS");
try {
this.missingReadingDate = sdf.parse(missingReadingDate);
} catch (ParseException pex) {
String defaultTime = "1900-Jan-01 00:00:00.000";
logger.error("Wrong dateformat: " + missingReadingDate + ". Using default. (" + defaultTime +")");
try { this.missingReadingDate = sdf.parse(defaultTime); }
catch (Exception ex) {}
}
}

public int getPowerDownSeconds() {
return powerDownSeconds;
}

public void setPowerDownSeconds(int powerDownSeconds) {
this.powerDownSeconds = powerDownSeconds;
}
}

Please help on this . I am using Maven to build the project. After generating jars , am checking the class file whether it is getting updated or not, the propety is updated with setter and getter methods.
Still i am not able to find the root cause this Exception. Spring Configuration files are loading in one application and this Class is in other application.

Please help to resolve this exception

below is the Exception Stack Trace for org.springframework.beans.NotWritablePropertyException.

2013-03-20 10:01:28,421 FATAL [MeterMaidLauncher] [PLAT:config.error] Error creating beans: Error creating bean with name 'deliveryController' defined in class path resource [appContext/delivery.xml]: Cannot resolve reference to bean 'deliveryResponseService' while setting bean property 'responseService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'deliveryResponseService' defined in class path resource [appContext/delivery.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'powerDownSeconds' of bean class [com.telenor.cinclus.metermaid.delivery.impl.DeliveryResponseServiceImpl]: Bean property 'powerDownSeconds' is not writable or has an invalid setter method.

naveen

I'm going to guess that Spring doesn't like powerDownSeconds having the setter and getter take and return a primitive int. Try Integer instead.

Thanks James for reply, but i tried with Iteger , getting same Exception.

How about String? Just like you have done for the date method.
