Hi Samid,
The issue related with your host entries under /etc/hosts file .
java.net.UnknownHostException: sapsleora: sapsleora
The exception is really saying is that there is no known server with the name "local".As per me you're trying to connect to your local computer. Try with the hostname "localhost" instead, or perhaps 127.0.0.1/::1
Your host file entries would be like as below:
127.0.0.1 localhost.localdomain localhost
<IP-address of your server> <hostname of your system>
Save the host file & retry the SWPM.Hope this time you'll get the successful execution.
Regards,
Gaurav
