Hi Kapil,
I have also just replied to your other thread (the network timeout error you get in the HTTP client), and I am beginning to think you may be trying something that is impossible?! With "SAP back-end system(HANA Server)" do you mean a SAP system (= ABAP system), which is able to process RFC and HTTP requests, or do you mean a HANA database, which is able to process SQL commands sent via ODBC/JDBC protocol?
I'm not familiar with databases, so I'm not sure, whether there are also databases that are capable of receiving and processing HTTP requests (and whether the HANA database in particular is able to do this), but I would assume, that even if a DB is able to act as HTTP server, some additional customizing and setup on the DB would be necessary for this. If you are sending HTTP requests to a port on the DB, which is expecting SQL commands, this could explain all kinds of strange behavior and errors...
Perhaps we should go back one step and take a detailed look at what you are trying to do and what you setup so far (and what error you are getting where).
Best Regards, Ulrich
