Fatal Read Error: Could not read or parse the JNLP file at

[JohannT]

Hi,

my webstart app runs fine with OpenWebStart 1.9.1 and JDK8 from a local tomcat 8.5.59 on my machine. But the very same app in the same configuration startet from our developer test server on the LAN always throws this error "Fatal: Read Error: Could not read or parse the JNLP file at 'file:/C:/Users/user/AppData/Local/Temp/umwelt11.jnlpx'."
The 'umwelt11.jnlpx' file was downloaded by ows into that folder prior to the error message. Oracle webstart has no issues to start the app from that location. Any hint to look for to solve the problem is appreciated.

This is the ows-stage1.log, there is no ows-stage2.log:

Your jnlp file has: <jnlp spec="1.0+" codebase="http://apptest:8080/Umwelt11/" href="umwelt11.jnlpx">

OWS is not able to download the jnlp file from the server:
downloadFrom exception: Server returned HTTP response code: 403 for URL: http://apptest:8080/Umwelt11/umwelt11.jnlpx

Code 403 means that you don't have permission to access the resource identified to by the URL

Request please do not copy logs from the console, instead send log files. See OWS Guide for logging.

Also request you to buy support for guaranteed response to your posts on the forum and to enable us to maintain OWS opensource project.
