How to connect a local java application to HANA as a Service

Dear all,
I need to develop a Java application, connectinig to HANA service runnning on Cloud Foundry in SCP.
The JDBC connection string that I see in VCAP_SERVICES contains the port 443 and therefore a JDBC connection that is expecting the 3xx1y pattern cannot take place.
I was trying to setup chisel but am not getting as far as I need and am not sure is stilil needed.
Please advice.
