MessageBroker already defined from MessageBrokerServlet

[bestwick]

Hi All!

I've tried to build a flex-BlazeDS-Sring project.

I have got this error:

org.springframework.beans.factory.BeanCreationExce ption: Error creating bean with name '_messageBrokerDefaultHandlerMapping': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationExce ption: Error creating bean with name '_messageBroker': Invocation of init method failed; nested exception is java.lang.RuntimeException: MessageBroker already defined from MessageBrokerServlet with init parameter messageBrokerId = '_messageBroker'

What could be the error?

Thanks

That error is generally caused by 1 of two possible scenarios:

1) You are somehow loading the application context containing the <flex:message-broker> multiple times (search the forums for a more detailed explanation of this)

2) The app failed to startup the first time, you made some changes and just restarted the app without restarting the server (this was due to some improper resource cleanup after a failure and has been fixed in the upcoming 1.0.1)

Thank you for your quick ansver!

Yes after reading forum posts I know that this error could come when my context loaded more then one.

But

I solve my problem so:

I added to ads-servlet.xml:

<!-- Controller handler adapter, hogy a Controller interface-t implementalo osztalyok tudjanak requestet kiszolgalni. -->
<bean class="org.springframework.web.servlet.mvc.SimpleControll erHandlerAdapter"/>

<bean class="org.springframework.web.servlet.handler.SimpleUrlH andlerMapping">
<property name="alwaysUseFullPath" value="true" />
<property name="mappings">
<props>
<prop key="/messagebroker/*">_messageBroker</prop>
</props>
</property>
</bean>

thanks again
bestwick
