Error using SOAPRunner: XML document must have top level element

[Former Member]

Hi all,...................xMII 11.5.3 b66

I am attempting to consume a BLS transaction as a web service from a J2EE app.

When I test it with http://naholldo31020/Lighthammer/SOAPRunner/Amy/GetListOfPlants I am getting an error message from the browser. The BLS transaction works fine when called from a Query template. What am I missing?

The XML page cannot be displayed 
Cannot view XML input using style sheet. 
Please correct the error and then click the Refresh button, or try again later.

Hi Amy,

here is an example how you can call a WS via http GET:

http://<server>/Lighthammer/Runner?Transaction=<path_to_your_TRX>&XacuteLoginName=YourAccount&Xacute...

Please note you do not need to use credentials in case you calling localhost.

I think in your case this should be the right url:

http://naholldo31020/Lighthammer/Runner?Transaction=Amy/GetListOfPlants&XacuteLoginName=YourAccount&...

Please change parameters for

- XacuteLoginName

- XacuteLoginPassword

- outputparameter (you can specify * or one of your transaction output parameter)

Hello, Ottavio.

While that URL technique does indeed invoke the same BLS transaction, it uses a somewhat different mechanism to do so (not SOAP-based).

Personally, I think the "Runner" mechanism is optimal, as it allows maximum flexibility in output data structures, output content types, and is generally much higher performance (one less layer to deal with).

However, many client applications can only consume SOAP-style web services.

You can't (generally) test SOAP services directly from a browser. Otherwise, you won't be "posting" the appropriate XML SOAP input message to the service.
