Hi,
I have created a very simple 2 state mxml file(attached
below) where you submit a name which is passed to a RemoteObject
which appends "Welcome " to the input string & returns the
whole string back.
The java class which does this is,
package samples.SimpleRemoteObject;
public class Echo {
public Echo(){
}
public String getString(String str){
return "Welcome " + str ;
}
}
I have added the following to flex-remoting-service.xml under
c:\tomcat\webapps\flex\WEB-INF\flex,
<destination id="EchoString">
<properties>
<source>samples.SimpleRemoteObject.Echo</source>
</properties>
</destination>
The <default-channels> & <adapters>
definition was already there.
I also put Echo.class under
C:\tomcat\webapps\flex\WEB-INF\classes\samples\SimpleRemoteObject.
After Tomcat(v5.5.9) is started, it correctly loads the
initial page
at
http://localhost:8080/flex/SimpleRemoteObject/SimpleRemoteObject.htmlbut after I click on submit, I always get "Error: Unknown
destination 'EchoString'". I have tried renaming the destination
names but there is no change in behavior.
Please let me know what am I doing wrong. All the samples are
running fine
though. This is my first attempt on doing something with
Flex.
Thanks,
Aejaz
