Deploying Gadget to MWS Problem

,
#1

Hi All

I’m returning to webmethods after a few years on another project.
I’m trying to develop a new inbox landing page using the business console but the first, and very basic, problem I encountered is the following exception on trying to deploy the HelloWorld example from the documentation.
I am working with webmethods 10.3 & the business console default tabs all work ok, but I can’t see what the problem with the deployment is.
I deployed using Designer to a remote MWS & have tried both a Portlet project & a Gadget project with the same result.

Please help, any ideas welcome!

Hi Ewan,

looks like one of the XML files in the project has additional content before the “<?xml ... ?>” tag.
Or one of these files does not match its encoding with the encoding specified in th xml-tag.

Hi Holgar

Thanks for your quick response.

On checking the xml files I can see that the gadgetDefinition.xml is empty & complaining about it!
On adding information in the editor it doesn’t allow me to save & the xml never updates.

Am I missing something in Designer do you think - I was just following the documentation

Designer logs show this error

Hi Ewan,

sorry, in this case I will no longer be able to assist you as we are currently on 9.12 and we only have used CAF-Portlets so far.

Lets see if there are other community members around who know better.

Regards,
Holger

For the moment I can manually add the xml definition & publish to the server!

Thanks Holger
