HI All, I am working on a POC to see if the ITX REST API can call  an  ITX map and execute it. Has anybody out there tried to do this, if so would you be willing to share an example of how you accomplished it using ITX and REST API.

 

Thanks Tom W

Hi ,

I am trying a POC with JSON format using the Open API importer - I tried generate a sample map for calling webservices using the REST API.

Steps followed:

1) File --> Import --> OpenAPI

2) Provide the swagger.json file

3) select an operation to generate a type tree and adapter command line properties --> "Post" option

4) select  "Use IBM transformation Extender map to call REST api" --> Next

5) select "Generate sample source" --> Next

6) Encounter below type tree importer - Error .

"

java.lang.NullPointerException

I am unable to generate the sample map due to type tree importer issue. But I am able to generate the type tree using the JSON importer with the same JSON file.

Can someone help me on this issue and provide any steps you used for webservice call using JSON.

Thanks !

I recommend you log this with IBM as a support call.  It seems unlikely it will be solved on the developerWorks Forum, and a copy of your files will be required to move investigation forward.

Thank you.

Hi,

I managed to get it to work with the Launcher, but the path is not very easy.

I'd rather document a more proper way of doing things, but will see if I can share my current version.

I hope to be able to do so soon, but I need to rework it, since I did not document every thing. As usual, the "obvious" steps are complete mystery a few months later... I discovered it the hard way afetr a PC crash and a full reinstallation!

Dear all,

 

here's a (very dirty) sample of a wroking scenario. The PDF documents the rough steps to make it work, and the project contains all you need to replicate it.

I used the MongoDB adapter to put to a MongoDB database, since it's more fun and actually quite easy.
