[Laszlo-dev] Rest Support

[Henry Minsky]

I'm taking a look at this. Can you tell me if there is an easy way to  you
get Tomcat server to return a 401 code? If I mark
a file as unreadable, I am getting back a 404 code.

<canvas width="100%" height="80%" debug="true">
  <debug  fontsize="12"/>

  <dataset name="mydata" src="http:foo.xml"
           onerror="Debug.write('onerror', this.errorstring)"
           ondata="Debug.write('ondata', this.data)"
           request="true"/>


</canvas>


this returns the following in the debugger in swf8

 «LoadObj#0| err.lzx (loading)» «LzLoader#1| err.lzx (loading)»
ERROR: data source error for http://127.0.0.1:8080/trunk/test/post2/foo.xml:
HTTP Status code: 404:Not Found
onerror data source error for http://127.0.0.1:8080/trunk/test/post2/foo.xml:
HTTP Status code: 404:Not Found

lzx> mydata.errorstring
'data source error for http://127.0.0.1:8080/trunk/test/post2/foo.xml: HTTP
Status code: 404:Not Found'
lzx>



By the way, you won't be able to support full REST API transactions in
non-proxied mode in swf7/8 because the Flash player
does not let you specify PUT or DELETE request . These are supported by the
proxy server though, I am pretty
sure. If they aren't then it's a bug..

In DHTML, I believe PUT and DELETE request methods are supported in SOLO
mode.
