Using Https to connect to the PushServer

mahen

Hi,

I am using Https to connect to the LightStreamer server using com.lightstreamer.ls_client.LSClient. The pushServerUrl in com.lightstreamer.ls_client.ConnectionInfo class passed in to LSClient has a url of the form https://XXX.XX etc.
When i try to connect in this way, i am getting the following error:

do i have to put any certificates in a particular location in LightStreamer installation?
or, do i have to do something else/
Thanks in advance for any pointers.

You must have enabled the 443 port on the Server by uncommenting the <https_server> element in the Server configuration file. There, you also find the <keystore> subelement, where the path to your certificate files is supplied (see the embedded comment for notes on the certificates).

The keystore provided in the "conf" directory is self-signed. We provide it because it allows you to try https access from a browser (the browser will prompt you for acceptance). Can you access the Server in https successfully from a browser?

Access in https from a java program, on the other hand, requires that either a correct certificate is mounted on the Server or, in case of a self-signed certificate, that the same certificate is supplied to the JVM "truststore".
This can be done by application code, with no involvement of Lightstreamer Java Client Library.
Anyway, please show us the corresponding Server log for a check.

Thanks Dario for the reply.
It was an issue with the client. I had to set it up properly by giving the truststore etc. now it looks fine.

Hi everybody !!
I also wanted to use Lightstreamer with https, but it didn't work. But the problem is that i didn't find the <https> tag in my lightstreamer_conf.xml.
Where can i find this tag ?
