Configuring mailSender throws PropertyAccessExceptionsException

[mcbeelen]

Hello,

I was trying to configure a mailSender in my application using the following piece of code:


<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailS enderImpl">
<property name="session" ref="mailSession"/>
</bean>

<bean id="mailSession" class="org.springframework.jndi.JndiObjectFactoryB ean">
<property name="jndiName">
<value>java:comp/env/mail/Session</value>
</property>
</bean>


When I started my application the following exception was thrown:

2007-02-26 13:39:38,943 ERROR [localhost].[/sponsoring] - Exception sending context initialized event to listener instance of class org.spri
ngframework.web.context.ContextLoaderListener

I have the same configuration in another webapp and that application does get initialized properly.

Any suggestions about what is wrong and how I can fix this?

I'm using Spring 1.2.8 for an application running on Tomcat 5.5.12 in JVM 1.5.0_07.

With kind regards,
Marco

Failed to convert property value of type [javax.mail.Session] to required type [javax.mail.Session]

This kind of error message normally points to the classpath. Do you have duplicate copies of javax.mail.Session in different classloaders (e.g. one in the server and one in the app)?
