Issues: Java Script and SCA

I have some issues with using Java Script and SCA. After look some examples,
I have noticed the usage of this structure:

#SCDL:

<composite>

    <component name="Calendar">
        <t:implementation.widget location="uiservices/calendar.html"/>
        <service name="Widget">
            <t:binding.http uri="/calendar"/>
        </service>
        <reference name="calendarRef" target="CalendarComponent">
             <t:binding.jsonrpc/>
         </reference>
    </component>

    <component name="CalendarComponent">
        <implementation.java class="package.Class"/>
                <service name="CalendarService">
            <t:binding.jsonrpc/>
      </service>
    </component>

</composite>

#Java Script

        <script type="text/javascript" src="calendar.js"></script>

        <script language="JavaScript">

            //@Reference
            var calendarRef = new Reference("calendarRef");

            function init() {

                try	{
                    calendarRef.someMethod();
                }
                catch(e){
                    alert(e);
                }
            }

 </script>


However, if I execute this, I get a "TypeError: calendarRef is undefined".

Am I missing something?

Thanks

Could you please make your code available, them me or others can help
more easier. If this is a sample, just add it to trunk, even if it's a
work in progress.

Thanks Luciano for the advices. I have resolved part of the problem. Now, I
am getting the following warnings:
*
Aug 29, 2008 11:57:23 AM
org.apache.tuscany.sca.assembly.builder.impl.ComponentConfigurationBuilderImpl

Any idea?

Re: Issues: Java Script and SCA

Posted by Luciano Resende <lu...@gmail.com>.
On a high level look, it looks right, so some things to check :

   - When you start the application, are you seeing any warnings on
the console ? Usually a missing dependencies will cause your binding
or implementation not to be recognizable by the runtime and it then
display some warnings like :

      Element {http://www.osoa.org/xmlns/sca/1.0}implementation.java
cannot be processed.

   - Another thing is to check if you have your interfaces annotated
as remotable (@Remotable)


If you do see warnings, maybe it's a good idea to look at them or
provide them so I can take a look.

If this does not help, please provide a patch attached to a JIRA and I
can take a look at it.
