Re: [Connotea-code-devel] post not implemented ?

[Benjamin G. <go...@in...>]

OK,

Apologies all, for using this list as my own personal "intro to java  
web programming" course..  Just to finish this off, the following  
code frag does what I was trying to do

String encodedData = "uri="+URLEncoder.encode(uri,"UTF-8") 
+"&tags="+URLEncoder.encode(tags,"UTF-8");		
URL connoU = new URL("http://www.connotea.org/data/add");			
HttpURLConnection conno = (HttpURLConnection) connoU.openConnection();	
conno.setDoOutput(true);
OutputStream os = conno.getOutputStream();
os.write( encodedData.getBytes() );
int code = conno.getResponseCode();
System.out.println("response code from connotea="+code);

If anyone else is having trouble reading and writing to the api from  
java, please do let me know - think I've made it through most of the  
cases.  The only one I haven't finished yet is the job of writing to  
the connotea wiki from code.  Seems that it is possible to do that  
via browser emulation (cookies etc.) but it would be cool if it was  
added to the API.

cheers all
-Ben
