Hi,

I have Rapidanalytics running on a server and I want to access it from RapidMiner 5.1.6 on a different machine.
I have added the Remote repository, but I cannot connect to it. I have no idea how to fix the unsupported content type exception.

Please let me know if you have any clue how to fix this.

Thanks, Zoltan

    Hi Zoltan,

    this is almost certainly because of a wrong hostname or IP address. E.g., when you use an unknown host, many DNS servers direct you to a search page (like OpenDNS does). This has content type text/html, as opposed to the expected XML expected from RA, hence the error message. This DNS redirect is a pain. Make sure your server uses the correct hostname that can be resolved from the client.

    Best,

    Hi Simon,

    Thanks for the DNS idea. After some reboots and some time, the problem misteriously disappeared and I am a happy RapidAnalytics user since then. :)
    I remember that I had the same problem when I first tried RapidAnalytics several months ago, and it started working after some time. You are right that this can be a network problem as both installations happened on the same network. This time I have tried both the hostname and the IP address, neither worked in RapidMiner, but both worked in a browser which might mean that the problem is Java-specific.

    If I will need to install another RapidAnalytics then I will try to investigate further.

    Best, Zoltan

    Hi,

    one other remark on this issue: If you can't set your hostname, you can also edit

    server/default/deployers/jbossws.deployer/META-INF/stack-agnostic-jboss-beans.xml

    and enter the hostname there (property "webServiceHost").

    Best,
    Simon
