QueryResourceProperties
Description
This interface allows a requestor to query the resource properties document of a managed resource using a query expression.
The given expression is evaluated against the resource properties document of the target resource.
Note that although this request allows to declare a dialect for the given expression, only the XPath 1.0 dialect is supported at the moment.

01 |
The SOAP <Envelope> is the root element in every SOAP message, and contains two child elements, <Header> and <Body>. |
02 |
The SOAP Header will contain all metadata used for identifying the conversation participants (requestor and provider). |
03 - 05 |
Convey the target endpoint also known (in the request phase) as service provider. |
06 - 08 |
Indicate this is a QueryResourceProperties request. |
09 - 11 |
Convey a unique identifier associated with the current message. This will be used for request / response messages correlation. |
12 - 15 |
Provide the address of the source endpoint also known (in the request phase) as service requestor. |
17 - 19 |
This indicates the target resource of this request. Specifically the line 18 contains the resource identifier. |
20 - 22 |
The QueryResourceProperties request. |
22 |
The XPath expression that will be evaluated against the resource properties document of the target resource. |

Description |
---|---|
01 - 03 |
Convey the recipient of the response message. Note that this time we are talking about the service requestor; The address matches the <wsa:From> previously found in the corresponding request. |
04 - 06 |
Indicate this is a QueryResourceProperties response. This is done as usual using a wsa:Action that is part of WS-Addressing specification. |
07 - 09 |
Convey a unique identifier associated with the current response message. |
10 - 12 |
This element provides the identifier of the correlated (request) message. |
13 |
The <wsa:From> element (part of WS-Addressing specs too) identifies the source endpoint, the originator of this response message. |
14 - 16 |
This is the address of the source service endpoint. As said for lines 01-03 this time this is referred to service provider (the message originator). |
17 - 20 |
As part of wsa:From element, this contains (specifically on line 18) additional information needed for identifying the originator of this message. |
21 - 23 |
This is the QuertyResourceProperties response element which contains the result of the evaluated query. |
22 |
This element represents the requested property. Note that the name of the element is the name of the property. |
Faults
- ResourceUnknownFault : There's no resource on QMan associated with the given reference information (soap address and identifier).
- ResourceUnavailableFault : The requested resource is unavailable. This fault should indicate a transient condition. That means a requester might resend the message.
- UnknownQueryExpressionDialectFault : Remember that only XPath 1.0 is supported. This fault is thrown if another dialect is declared on request message.
- InvalidQueryExpressionFault : The given expression is not valid according to the corresponding dialect (XPath).
- QueryEvaluationErrorFault : The evaluation of the given expression thrown an exception.
