Update content file from the APPLET (REST API)

[viron82]

Problem:
Can’t  realize updating of a file from the APPLET.
QUESTION 1:
How I can look at examples? Like this http://localhost:8080/alfresco/service/api/upload
I don't know as to look at examples to which references of this kind refer because they are absent.
I have received on demand a tooling Alfresco_SDK_Extentsion_Example_1..3.zip, but there these examples aren't present.
QUESTION 2:
What parameters format I should use  for REST API  http://localhost:8080/alfresco/service/api/upload
in my request.
At realization of function of updating of a file I have faced that there is no due, clear description REST API for this functionality. Despite a seeming considerable quantity of the information, by more detailed consideration absence of the necessary information on this question is found out.

this my code, but this don't work.
I get right ticket but I can't automatic authorization  ( I get popup window for enter login and password ).

And next server response to my applet error with code = 500.

Any ideas?

Hi!

1) I use the source code of Alfresco as reference to see how the things are implemented. The address of the SVN repo is this - svn://svn.alfresco.com/alfresco/HEAD

2) You can view list of all webscripts [1] where for each webscript you can see the parameters and HTTP methods it provides

1- http://localhost:8080/alfresco/service

Hope that helps.

And another thing. I recommend using of commons-httpclient for interactions with rest apis. It's very powerful and easy to use library.
