Hi Marcio,
the URL you mentioned is on our internal PROD landscape, i.e. only accessible within SAP network.
It is, for instance, NOT accessible from the trial landscape, which is one of the two external landscapes (next to Factory).
To enable such kind of on-demand on-premise connectivity, you can use the SAP HANA Cloud Connector (see https://help.hana.ondemand.com/help/frameset.htm?e6c7616abb5710148cfcf3e75d96d596.html). Alternatively, you could also deploy our "someservlet" to trial, then the access from your other trial application is no problem at all.
Regards,
Timo
