Service access via Flex

[Mark Ellul <ma...@catalystic.com>]

Hi

We are looking at creating a Flex Front end to Ofbiz.

I have been looking at BlazeDS as a way of sending data to a Java Class
where I would want to call Ofbiz Services that are not exported (for
security reasons)....

How can I call a Ofbiz service that is not exported from Java?

I have looked at SOAP and RMI and both need to be exported...

Is it possible?

If not, any ideas on how I could do it?

Thanks and Regards

Mark

Hi David,

Thanks for your response...

I was planning on running my external facing code in the JVM, another reason
I want to use BlazeDS is that it uses a binary protocol, so its more
efficient at sending lots of data.


SO Basicall I will be running it in the same container and my issue is well
the DispatchContext.

I have pasted my test example below... What I have is a service helloPerson
and my testBlaze method which is called by a AMF handling servlet...  I was
thinking that if I had the ServletConfig of the AMF request, I could some
how... be able to create the  Dispatch Context...

But I am a little lost...

Is this the correct approach? if so Could someone point me to some code that
might help me?

If not how would I do it?

Thanks

Unless you're running code in the same JVM, the intention of the  
export flag is to keep it from being run externally.

If you want to get around that for your code, it needs to run in the  
same container (JVM).

BTW, if you make the service responsible for its own security and  
authentication, then it should be fine to export it.
