problem sending an email with javamail

[Andre.almeida]

Good morning guys,

I'm facing a problem with my e-mail sender. I have this conf:

        <bean id="mailSession" class="javax.mail.Session" factory-method="getInstance">
		<constructor-arg>
			<props>
				<prop key="mail.smtp.auth">true</prop>
				<prop key="mail.smtp.socketFactory.port">465</prop>
				<prop key="mail.smtp.socketFactory.class">javax.net.ssl.SSLSocketFactory</prop>
				<prop key="mail.smto.socketFactory.fallback">false</prop>
			</props>			
		</constructor-arg>
		<constructor-arg ref="smtpAutentificador"/>
	</bean>
	
	<bean id="mailSender"
		class="org.springframework.mail.javamail.JavaMailSenderImpl">
		<property name="host" value="smtp.gmail.com" />
		<property name="session" ref="mailSession" />
	</bean>
	
	
	<bean id="templateMessage" class="org.springframework.mail.SimpleMailMessage">
		<property name="from" value="server@email.com"/>
		<property name="subject" value="Testing"/>
	</bean>
	
	<bean id="email" class="com.utils.EmailServlet">
		<constructor-arg ref="mailSender"/>
		<constructor-arg ref="templateMessage"/>
	</bean>

        <bean id="smtpAutentificador" class="com.utils.SmtpAutentificador">
		<constructor-arg value="my-mail@gmail.com"/>
		<constructor-arg value="myPassword"/>
	</bean>

        <bean id="emailServlet" class="com.utils.EmailServlet" >
		<constructor-arg ref="mailSender" />
		<constructor-arg ref="templateMessage" />
	</bean>

and the classes that I send the e-mails are just the same as posted here. When I run it in my local machine, everything works fine, but when I deploy it on my JBOSS and try to send an e-mail I get this error:

07:54:38,963 ERROR [[/web]] Exception while dispatching incoming RPC call

I use javax.mail-1.4.1 but when I try to use javax.mail-1.4.4 the same error occurs.
Do you guys have any idea what's going on?

Thanks for your help.
