[gridsam-discuss] run-time '...JobDefinition not found ...' bug

[Vesso N. <ve...@do...>]

There's a problem with certain GridSAM Client installations.

Symptoms:
Using CLI from the Client side to send a valid JSDL through 
gridsam-submit results in an error returned with the message:
"No jsdl:JobDefinition element can be found in the request. Please check 
your input and the namespace declarations."

Reason:
In the file GridSAMService.java the call to
"...
if(pRequest.selectPath(GridSAMSupport.XPATH_NAMESPACES_DECLARATION 
+          
"/gridsam:submitJob/gridsam:JobDescription/jsdl:JobDefinition").length 
== 0){
..."

fails as the XPath evaluation fails even though the JSDL is valid and 
the JobDefinition element is present.

The failure is caused by the Body part of the SOAP message sent from the 
Client side containing duplicated 'sumbitJob' XML elements
- i.e.  effectively changing the path to the JobDefinition element:

incorrect SOAP:
