Error 403 connecting to Desktop engine

Thu, 04 Feb 2016 02:26:51 GMT

I need to query information about a Qlik Sense app from a Java program, using the Engine API.

Though I will eventually use the enterprise edition, I'm trying to do my development on a Desktop version, to keep things simple. Turns out to be not so simple. All attempts to connect to the engine on port 4848 get a consistent 403 error (Yes, the Desktop app is running. When it is not, an expected connection failure occurs.)

Everything I could find by way of Google on this issue was not helpful.

The JSON structure to simply query the engine for a list of apps seemed simple enough in the API explorer. My program creates the same JSON RPC request:

{ "handle": -1, "method": "GetDocList", "params": [], "id": 6, "jsonrpc": "2.0"

}

which I send to the url http://localhost/4848/. (Since no app is involved in a request to get the list of apps, I didn't put anything in the path as the resource to be accessed.)

I get a solid 403 error. Trying other variants, such as using 127.0.0.1:4848, gets the same error.

Since the api explorer works, it is not surprising that the connection exists, according to netstat:

TCP 127.0.0.1:4848 <machinename>:65237 ESTABLISHED

and the firewall appears to be allowing qliksense.exe access.

Hi Gene,

this is working fine. You have to open a WebSocket and Connection to the port 4848 and send you requests.

For paid Help you can ask rbecher he has already written all that in JAVA.

Problem resolved itself with a new comm support library (tyrus).
