> (Fatal: Application Error: Cannot grant permissions to unsigned jars. Application requested security permissions, but jars are not signed.)

The log says that jars are not signed. Please sign the jars of your application.

Henceforth, please send log files instead of copying logs from console.

> Are you trying to use OWS in an enterprise environment? Yes - So we have firewalls, Anti-Virus, Intrusion Protection in place and most users will connected to Network via VPN > So did you try the above mentioned URLs in a browser in the same environment (behid firewal, vpn etc) as where OWS is run...

> the AccessibleScollDemo.jnlp doesn't have the jnp\information\shortcut node. True. I added the tag and removed href in jnlp and even then the shortcut was not created. It seems JWS shortcut creation depends on whether you choose to cache the app or not. This option is available in Java Control pan...

> To make it easier lets just take server1/xyz.jnlp into account. If i change the "Start in" directory of the shortcut "server1" to, e.g. "C:\tmp", it will be reset to the OWS install dir at the next run of the jnlp. I can confirm this behavior both with OWS 1.5.0 and ...

Hello Nick, Which version of OWS are you using at present? > 1. Updating OWS always fails with a Connection reset; Just to clarify, you started itw-settings. Did you choose Updates > Check for Updates Now? Or do have the option "Check Automatically for Updates " checked. Are you saying tha...

> I checked the updates in 1.5.1. But unfortunately this won't help me. I would need some kind of OWS option to just create shortcuts if they don't exist and keep the shortcut untouched otherwise. But if i understood you correctly, this is not possible at the moment. > What makes you think that OWS ...

Hello Which OWS version are you using? From your description your OS is Windows. " Java application (JNLP) which is deployed on different servers (e.g. production, test, uat, ...). Each of those applications create a shortcut on the desktop with different names" OWS names the Desktop Short...

The last statement in log file is "Download of resource WebNMS.jnlp will start now!". It is not clear what is happening after this point.

Can you please try with the latest OWS 1.5.0 and send the logs if it does not work?

Thanks

Hi, You are starting a jnlp file WebNMS.jnlp which is present on your C: drive. This Jnlp file seems to have an href that points to "https://10.39.234.152:8443/conf/WebNMS.jnlp" OWS tries to down load this resource. But after this there is nothing in the log. Can you please send us the log...

We will need to look at all your jnlps, your cache and your server set up to really understand your issue. We can make an offer for paid support in case you are interested.

Please have a look at https://openjfx.io/openjfx-docs/maven . Then you can build: 1. jar file with manifest have security permissions using maven-jar-plugin 2. sign the jar file also the openjfx jar files using maven-jarsigner-plugin 3. create jnlp file with your app jar and openjfx jars like the on...

Please have a look at https://openwebstart.com/docs/FAQ.html# ... enwebstart.

In order to avoid a possible conflict between OWS and the actual JNLP applications, both icedtea-web and OpenWebStart dispense with as many dependencies as possible. Therefore, OWS uses its own logging framework which is not affected by the Log4Shell exploit. The code for logging in OWS can be viewe...

But even when I start the myapp.jnlp which was downloaded from app_v2 and which has codebase app_v2 from my Downloads folder by right clicking it and choosing Open with -> OWS, the wrong application gets started. So on the server: app_v1.host.com/myapp.jnlp has code base and href: <jnlp codebase=&q...

> I click on a link "app_v1.host.com/myapp.jnlp" in my browser, the myapp.jnlp is downloaded and then automatically started with OWS because of the file association in Windows. > Is OWS started automatically or are you supposed to "open" the downloaded jnlp? My experience with Ch...

Firstly, OWS works with the URLs provided to it : 1. as an argument to javaws executable 2. the codebase and the href in the jnlp 3. then the jnlp pointed to by the href OWS does not manipulate the URLs. So it is important to look at the Jnlps and their attributes like codebase and href to make sure...

You can check the source code or check if the app is running in a sandbox (there should be an icon on the window).

We have not tested on RHEL but it should work.

Hi,

We do not provide .rpm..

This link https://github.com/karakun/OpenWebStart/issues/154 shows how to convert .deb to .pm which you said you have already done.

I hope you installation was successful.
