Set web service to use with the connector

Hi,

I have created a web service in .asmx format and now need to use it in BonitaSoft, I'm using version 7.

How do I configure the SOAP connector to access the web service.

I tried a configuration but i got the following error message:

**java.lang.reflect.InvocationTargetException
org.bonitasoft.engine.bpm.connector.ConnectorExecutionException: USERNAME=install | org.bonitasoft.engine.core.connector.exception.SConnectorException: org.bonitasoft.engine.connector.exception.SConnectorException: java.util.concurrent.ExecutionException: org.bonitasoft.engine.connector.exception.SConnectorException: org.bonitasoft.engine.connector.ConnectorException: Exception trying to call remote webservice
**

Grateful for any help,

Greetings!
