How are you connecting to Java ?

[Jose]

Hey, I'm using livecycle data services to connect to java... I found that the error child problem that we were talking in the oder thread was because I didn't defined the messageBrokerServlet. Now when I tried to define it I have trouble of configuration

my two config files looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<services-config>
 
    <services>
        <service-include file-path="remote-config.xml" />
        <default-channels>
           <channel ref="my-amf"/>
        </default-channels>
    </services>
    <security>

        <login-command class="flex.messaging.security.TomcatLoginCommand" server="Tomcat">

            <per-client-

authentication>false</per-client-authentication>
        </login-command>
        <security-constraint id="basic-read-access">
            <auth-method>Basic</auth-method>
            <roles>
                <role>guests</role>
                <role>accountants</role>
                <role>employees</role>
                <role>managers</role>
            </roles>
        </security-constraint>

        <security-constraint id="sample-users">
            <auth-method>Custom</auth-method>
            <roles>
                <role>sampleusers</role>
            </roles>
        </security-constraint>

    </security>
     <servers>
        <server id="my-nio-server" class="flex.messaging.socketserver.SocketServer">
         <properties>
                 
            </properties>
        </server>
    </servers>
    <channels>
        <channel-definition id="my-amf" class="mx.messaging.channels.AMFChannel">
            <endpoint url="http://{server.name}:{server.port}/{context.root}/messagebroker/amf" class="flex.messaging.endpoints.AMFEndpoint"/>
        </channel-definition>
        <channel-definition id="my-http" class="mx.messaging.channels.HTTPChannel">
            <endpoint url="http://{server.name}:{server.port}/{context.root}/messagebroker/http" class="flex.messaging.endpoints.HTTPEndpoint"/>
        </channel-definition>
    </channels>

<system>
    <manageable>false</manageable>
     <redeploy>
     <enabled>true</enabled>
            <watch-interval>20</watch-interval>
            <watch-file>{context.root}/WEB-INF/flex/services-config.xml</watch-file>
            <watch-file>{context.root}/WEB-INF/flex/remoting-config.xml</watch-file>
            <touch-file>{context.root}/WEB-INF/web.xml</touch-file>
        </redeploy>
    </system>

</services-config>



And If got a remoting-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<service id="my-service" class="flex.messaging.services.RemotingService" messageTypes="flex.messaging.messages.RemotingMessage">

<adapters>
        <adapter-definition id="java-object" class="flex.messaging.services.remoting.adapters.JavaAdapter" default="true"/>
    </adapters>

<default-channels>
        <channel ref="my-amf"/>
    </default-channels>

<destination id="mortgageService">
<properties>
            <source>flex.samples.spring.mortgage.Mortgage</source>
        </properties>
</destination>
</service>


and I get this exception:

I get an exception :
GRAVE: El Servlet /WebContent lanzï¿? excepciï¿?n de load()

If I comment the server tag I get the exception I posted on this thread before. any ideas? thanks a lot for your time

[Jose]

Vinod thanks for your help! I manage to find the solution at the end.. I had the jars everywhere and when I tried to put them under web-inf/lib tomcat start crashed so I put all the flex jar under tomcat/lib and now it works. When I access to messabroker/amf I see that it's working but now I've got another problem, When I execute my flex application I get a message like that:

[RPC Fault faultString="Cannot create class of type 'flex.samples.spring.mortgage.Mortgage'." faultCode="Server.ResourceUnavailable" faultDetail="Type 'flex.samples.spring.mortgage.Mortgage' not found."]
    at mx.rpc::AbstractInvoker/http://www.adobe.com/2006/flex/mx/internal::faultHandler()[E:\dev\3.0.x\frameworks\projects\rpc\src\mx\rpc\AbstractInvoker.as:216]

    at mx.messaging::MessageResponder/status()[E:\dev\3.0.x\frameworks\projects\rpc\src\mx\messaging\MessageResponder.as:222]

It's like it's not finding the class on the server but I see that the class is under web-inf/classes. the errors of configuration of flex and java doesn't give much information. I'm having a hard time to set it up, is it normal? Any help would be appreciate
