Upgrading from Spring 2.5.2 to 2.5.4

[adex]

Recently, I have upgraded spring 2.5.2 to 2.5.4. I am using JavaMailSender in my application to send e-mail to the users. Before upgrading, the application was working without problem. After i upgraded i got "java.lang.NullPointerException" for JavaMailSender object.

Is there any change in using "JavaMailSender" in Spring 2.5.4 ?


my bean defintion for JavaMailSender:

<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
      <property name="host" value="smtp.uio.no"/>
      <property name="javaMailProperties">
         <description>see java.sun.com/products/javamail/javadocs/com/sun/mail/smtp/package-summary.html</description>
         <props> 
         </props> 
      </property>
   </bean>

my bean definon for Email class:

 
   <bean id="no.uio.webapps.duoinn.Email" class="no.uio.webapps.duoinn.Email" lazy-init="true" scope="prototype">
      <property name="mailSender" ref="mailSender" />
   </bean>

stacktrace.:

It looks like you don't have a MailSender in your Email class. Are you creating a new one yourself or are you retrieving one from the ApplicationContext/injecting it?

I am injecting it.

For some reason your MailSender doesn't get injected, why I have no idea. The NullPointer is in your own class not inside the MailSender, you might try and remove the lazy-init and also make sure you aren't constructing any Email or Controller classes yourself.

Also what is on line 62 of your Email class anyway.
