Hello all,

I have a request to imnplement a WSDL service in order to send xn XML as request and to receive an XML with response.

The job I have created is.

Folder --> XML_INPUT -->WSDL Client

Just to see the response in the log file, but after XML_INPUT I'm getting the following error:

NRR_Target..XML_Input_20: com.ascentialsoftware.wsclient.ServiceInvocationException: Service invocation exception:

Any idea what can be the problem.?

This can potentially be a very complex process...."if" the wsdl describes nothing but a single large column to be sent to the service, then this is the general methodology.... (xmlinput to wsTransformer or wsClient, passing the xml in a single large column)...

...but if the real scenario is that the body of the SOAP request is complex xml, then it is not as simple.

How can you tell?

Have a testing tool at your side. I like SOAPui and another one from Actional....both can be downloaded for free; there are many others.

Load up your WSDL into one of those tools and then invoke the service...do you see a whole bunch of properties that have to be filled out, each that makes up the xml? ...or does it just give you a single property where you need to "paste" your already created chunk of xml?

Thanks for the reply, but I'm not a premium member and can't see the entire answers you have posted to me in the last 2 issues I opened.

Can you please add those in a different way?

Thanks a lot
