HELP: alfresco APIs and Services?

shamabbas

Hi,
I'm trying to integrate alfresco with my own developed application developed in Flex to upload and retrieve files. Please let me know what APIs and Services are being used in alfresco just to upload and retrieve files. And if also can help please let me know how to call these services in my Application. Actually im totally new so need some help. Please!
I'll be very thankful to you.

I'm really new to this my self, so i apologize if I'm wrong about something, but I hope this might be of some help.

The Webscripts Samples page in the wiki contains an example on how to upload files:

http://wiki.alfresco.com/wiki/Web_Scripts_Examples

As for downloading files there is a property called downloadUrl that applies to document objects, this is detailed out here:

http://wiki.alfresco.com/wiki/3.2_JavaScript_API#ScriptNode_API

So what you might do is to use a web script to retrieve the download URL for the file and then do a http request using the URL to download it.

Hi gronfelt,
Thanks for replying. I have picked code for uploading and downloading files in java from different forums. I'm facing authentication problems now. Session starts and right then end when upload any file. I don't know much about its authentication process but it generates ticket for password to pass which i really don't know how to do.
I asked many places but no help yet. If you'd know something let me know.
Thanks once again. I really appreciate you replied to me. And it will obvisouly help me the javascripts api link you sent. Other webscripts i have already worked in it.
thanks alotz!

What is the reason?

shamabbas

I'm using java code which was pasted here in forums to upload files in alfresco repository. Part of code is given below which is used for authentication purpose

               WebServiceFactory.setEndpointAddress("http://localhost:8080/alfresco/api");
                AuthenticationUtils.startSession("admin", "admin");
                System.out.println("Ticket::" + AuthenticationUtils.getTicket());
‍‍‍‍‍

But gave me following exception.
