### Fault Handlers

For details on how to inspect any SOAP Faults that are raised as a result of a server or transport error, see [Fault Handling](docId\:B5rX1jLUdhwoIc0UbNOsd).

### Tracing

For full SOAP tracing, run your Control API application by typing the following command:

```bash
java –Djavax.net.debug=all listVS
```

Alternatively, enable debugging within your application by adding the following line:

```bash
System.setProperty( "javax.net.debug", "all" );
```
