Posting to SDATA from Java fails
Posted: 23 Jan 09 6:26 AM

Hi all. I consume a webservice via a URI. I'm able to get the xml and change the element text. However, when I PUT the changed data to the server, the server response code is 200 but the data on the server never changed.
The server logs say:
Event Type: Information

Event Category: None
Event ID: 0

Time: 14:05:14
User: N/A

Description:

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp
and one for every element that I'm trying to post.
Does anyone have any idea what these error messages mean? How do I fix this. Your help will be appreciated.

So an exception is being thrown in the OnBeforeLoad of the web application. I would look at the rule and see what is it is trying to do. Maybe there is a piece of information required that is not supplied.
Good Luck on it. |

Thank you for the reply, Mark. You are correct in your diagnosis that information was missing. I was having a hard time making up the correct SAX document to pass back to the slx server. I solved this by downloading the xml from a known working URI. I parsed that xml from the file to see if it posted. It did. Then I started stripping elements until I came down to the minimum xml needed to PUT to the server.
My procedure was: 1) Download the xml from the URI using jdom and a xerces parser (the default one with jdom). 2) Extract the root and child elements and add to an ArrayList 3)Manipulate the data 4) Compose a string from this data in the format deduced from experimenting with the file mentioned in the first paragraph. 5) Parse this string with jdom into a SAX document and PUT to the server. Voila.
Some observations: 1) omit the prologue (delete it) if you're parsing with jdom. Jdom adds its own prologue when parsing into a SAX/DOM document. 2) If you are PUTting elements to the server and you omit one, that field will be updated on the server with a null value. |
