On swf version 4.0.10 we get the following: 





  

Using proxied mode:   we can get the error string   as in you example, but we 
need to get a user defined message with the error string 



e.g using the jsp file sent by Andre we can define a customized error message 



<% response.sendError(401, " My message "); %> 



How can we read the " My message " in the onerror handler? 





  

Using the non proxied mode calling dataset.getErrorString() still result in 
error “client could not parse XML from server” 





  

Any Ideas how to handle it? 





  

For our application we are still using version 4.0.8 and we are not able to 
upgrade to 4.0.10 since we are having XmlRpc calls and it seems that XmlRpc is 
not working well in version 4.0.10

Using the .jsp code from Andre to induce a 401 error, I am getting the onerror 
event and error string properly 


LzLoadQueue.XMLOnDataHandler success <?xml version="1.0" 
encoding="UTF-8"?><!DOCTYPE laszlo-data><resultset><error status="2" msg="data 
source error for http://127.0.0.1:8080/trunk/test/post2/foo.jsp : HTTP Status 
code: 401:Unauthorized"/></resultset> 
 «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.jsp : 
HTTP Status code: 401:Unauthorized 
onerror data source error for http://127.0.0.1:8080/trunk/test/post2/foo.jsp : 
HTTP Status code: 401:Unauthorized 
lzx> mydata.getErrorString() 
'data source error for http://127.0.0.1:8080/trunk/test/post2/foo.jsp : HTTP 
Status code: 401:Unauthorized' 
lzx> 

Are you sure you are actually being sent a 401 error from your back-end server?

I am trying to call REST APIs from openlaszlo. I tried to make a dataset http 
request and it worked fine on success. But in case where the REST returns an 
error like HTTP Error 401 – Unauthorized I can't read the error string or code. 
It behaves as the following: 
On proxied mode: dataset.getErrorString()always return null while in debugger 
there is a message showing the error type but we can't access it 
On non proxied mode: calling dataset.getErrorString() result in error "client 
could not parse XML from server" 
Using Xmlhttprequest is also not helpful where it always cast errors types to 
http error 500 

In order to support calling basic REST APIs, I need to get a clear HTTP Error 
code and also be able to read the http content in case of error.
