Is this a Spring IDE issue or I'm I wrong? (Spring-flex/wtp/Gilead)

[Tcharl]

Hi,

I got a stackOverFlow exception while mixing eclipse/spring IDE/M2Eclipse (works good out of the box).

My flex-appContext:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

		</property>
	</bean>




</beans>

The exception while I'm persisting a flex object:

Do you have any solution?

Thank you in advance, Tcharl

Hi Tchar!

Do you see this exception when running your app? Then I think this is not related to Spring IDE or the tooling in general and I would move this question to the Spring flex forum.

Hi Martin, thank you for your sollicitude!


The strange thing is that the project works well out of the box (running with cargo-tomcat).
It just fails with wtp/m2Eclipse and spring ide.

As I said before, the issue appears when I persist an objet (From flex to java). It works well in the other way.

I'm ok to duplicate the post in flex forum, but I still suspect a Spring ide Issue.

Here's my service-config.xml file if you see something strange:

<?xml version="1.0" encoding="UTF-8"?>
<services-config>

    <services>
        <!-- <service-include file-path="remoting-config.xml" /> -->
        <!-- le canal amf par défaut -->
         <default-channels>
           <channel ref="myProj-flex_webApp-amf" />
        </default-channels> 
    </services>

    <channels>
        <!-- définition des canaux amf, ici un canal standard (non sécurisé, non crypté) -->
        <channel-definition id="myProj-flex_webApp-amf" class="mx.messaging.channels.AMFChannel">
            <endpoint url="http://{server.name}:{server.port}/{context.root}/messagebroker/amf"
                      class="flex.messaging.endpoints.AMFEndpoint"/>
        </channel-definition>
  
    </channels>

                <pattern>Service.*</pattern>
                <pattern>Configuration</pattern>
            </filters>
        </target>
    </logging>

    <system>
        <redeploy>
            <enabled>false</enabled>
        </redeploy>
    </system>

</services-config>

I think that this is because my flex and webapp maven modules are pointing to the same service-config file (located un webapp/web-inf/flex webapp module) Spring ide must not interpret it well when a flex object is sent ti The server and fall into infinite loop. Any workaround? Patch? Suggestion?

[Martin Lippert]

Hey Tchar!

Can you attach a small sample project that demonstrates the problem? That would be great!

Cheers,
