POST request with JSON data to tRESTClient component

[Anonymous]

How can I create POST request with JSON data using tRESTClient component? I can only successfully send XML Document. Should I put JSON data inside XML element? It seems that is the only way to send JSON data. I am using talend 5.5.1.

You need to give us screenshots of your tRESTClient and your tRESTRequest configurations (schemas, Advanced tab, etc).

client side

service side

I didn't change any advance settings except log messages.

For the tRESTClient you should set both the Content Type and Accept Type to JSON. Only pass the JSON to the "string".
As a test for the service, connect the tRESTRequest to a tLogRow before the tXMLMap.

I added JSON to the string in the tRESTClient component so tXMLmap looks like this.

Now After running I get this error:

Exception in component tRESTClient_2
javax.ws.rs.NotFoundException

And on the service side I get:

Trying to write END_DOCUMENT when document has no root (ie. trying to output empty document).

Use tMap instead of the txmlmap. If not, txmlmap will create the xml in the body even if you don't put anything in this field.

Did you use a tLogRow before the tMap? You need to see exactly what you are getting from the tRESTRequest.

I replaced tXMLMap on service side and client side with tMap. And now I get on clide side still:

Exception in component tRESTClient_2
javax.ws.rs.NotFoundException

And on the service side I get

java.io.IOException: Illegal character: <<>

And inside tlogrow before tMap

That is working then. Look at the body field. It has converted your JSON to XML

So there is still the problem? If yes, could you put some screenshots? For better managing your body, i advise you to choose the option 'Wrap JSON Request' in the component tRESTRequest if that exists.

How should I convert this to JSON ?
I checked 'Wrap JSON Request'.

I still have the problem
