QueryResourcePropertiesRequest

[jo...@renfors.net]

Hi!

I'm developing a simple wsdm application with muse-0.5 for my Msc thesis. 
I've ran into problems with creating a QueryResourcePropertiesRequest to 
my wsdm application. How exactly i am supposed to build the request 
object?

This is the code snipped that i'm trying to get to work:

--------------------
QueryResourcePropertiesRequest request = new QueryResourcePropertiesRequest();
QueryExpressionType query = new QueryExpressionType();
MessageElement[] queryString = new MessageElement[1];
queryString[0] = new MessageElement();
queryString[0].addTextNode("*");
query.setDialect(new URI("http://www.w3.org/TR/1999/REC-xpath-19991116"));
query.set_any(queryString);
request.setQueryExpression(query);
Object response = getService().queryResourceProperties(request);
-----------------------
getService() returns the service stub.

I couldn't find samples for queries in the tutorial. Thanks in advance for 
your reply.

Hi Jouni,

Sorry for the late reply!

See 
http://svn.apache.org/viewcvs.cgi/incubator/muse/branches/v0.5/src/site/content/tutorial/disk/requests/query.soap?rev=157124&view=markup 
for an example of a QueryRPs request.

At a glance, your code for building up the request looks ok. The problem 
could be that the server is expectiong the XPath to not be wrapped in an 
element, i.e.:

<wsrp:QueryExpression 
dialect=".../REC-xpath-19991116">*</wsrp:QueryExpression>

as opposed to:

<wsrp:QueryExpression 
dialect=".../REC-xpath-19991116"><my:XPath>*</my:XPath></wsrp:QueryExpression>

Unfortanately, I'm not sure if the Axis-generated QueryExpressionType will 
  allow you to directly add a text node (i.e. set_any takes a 
MessageElement  , not a NodeIml).

I'd highly recommend that you upgrade to Muse 1.0, which implements MUWS 
1.0 and is being actively developed. We just released a beta last week 
[1]. Besides implementing MUWS 1.0 (which is now an official OASIS 
standard), it provides more features and better error messages. For 
example, if you send a request that is schema-invalid, the server will 
return a SOAP fault that describes exactly what part(s) of the request are 
not valid and why. If you do upgrade, we can point you at some good 
examples of building up requests programmatically using XmlBeans-generated 
types.

Good luck and let us know if you have any problems.

Regards,
Ian
