Thanks. FYI we do not use this "local file" capability, we just wanted to be clear on its functionality. which you've clarified. Seems a bit dodgy to trust local content IMO

Peeking at the IcedTea-Web code, it looks like "assumeFileSystemInCodebase" setting allows you to specify "file://" urls in the jnlp and to treat those resources as secure (as if they came from the trusted codebase). Is this correct?

Hmm thanks for the link, but I'm afraid I still do not understand. Does this option make a local jnlp file become trusted? If so, how else does OWS work if it cannot trust a local jnlp? I ask because (with older or more lenient browsers) using the old Java WebStart, the browser plugin could invoke J...

I'm trying to understand the configuration property "deployment.assumeFileSystemInCodebase". This /configuration page says "Defines if files from the local filesystem are always handled as if they would be part of the codebase." I don't really understand this. In my experience, a...

I Just tried locking down all possible settings and then examining the "OpenWebstart Settings" app to see the user experience. I have some questions about settings that are not able to locked down (at least as far as I can tell) JVM Manager Panel : Cannot lockdown the following settings? A...

In my experiments, I can certainly perform the initial install of OpenWebstart unattended. However, later on when an update check triggers, the subsequent install (update) of OpenWebStart is done interactively.

It would be nice to be able to make that update run unattended as well.

Thanks for the information regarding "forced" updates. I'll discuss with my company the possibility of becoming a sponsor.

Regarding the original question: Is it possible for an OWS update to run attended (after the user clicks to allow the update I mean)?

And I assume these files are proper java properties files, so we can use # comments in them?

Thanks for the response.

We may have some customer sites that disallow installation of older JVMs, that is why I was curious about support for later JVMs to run OWS. I believe that security is the concern.

[Followup to my own post] An one other question: Is it possible to force an OWS update? We will be locking down end-users pretty tightly with a locked-down deployment.config hosted on our server, so they will not be allowed to update OWS electively and we will set the update settings to NEVER. If we...

I'm playing around with OWS' update checking and installation. When an update check triggers I see that the user is presented with a dialog asking if they would like to update. This is followed by a series of wizards that step through the process. The final steps are the normal installation process ...

I see the numerous proxy settings mentioned in https://openwebstart.com/configuration/ These settings all start with the prefix "deployment.proxy" Do these proxy settings apply only to OpenWebStart itself (i.e. for fetching application jar files and other jnlp resources), or do the proxy s...

The current version of OpenWebStart installs a bundled 1.8 jre. To my understanding this jre is used exclusively for executing OpenWebStart itself and not for any .jnlp applications. Is there any capability to instead include a different jre version as the bundled jre, for example a java 11 jre? Tha...

Awesome feedback and suggestions, thanks! I apologize for wasting your time: the JDK7-compiled app is running fine under JDK11 now. Not sure why it was fidgety before but i had been playing with various options so... Your tip about looking for that log message was helpful - I massaged that output in...

I realize that OpenWebStart is intended to support JDK8+ runtimes, but as part of my evaluation of OWS I was required to try using it run an app that was compiled using JDK 1.7. If I use j2se="1.8*" in the jnlp, OWS runs the app just fine. If I use j2se="11.0.2" in the jnlp, OWS ...

I stand corrected! I guess I fooled myself because looking at your features-table, I saw that PersistenceService is "greyed out" which means "Low priority Feature". I made the assumption that meant it was not implemented, though in fact it is as I have now proven with our app. On...

Thanks for the speedy reply! The ability to define properties centrally and to lock them down sounds like just what we needed! Our client will need to perform/script the step of creating the %windir%\Sun\Java\deployment\deployment.config file right? And then also to create the actual properties file...

Is there any facility for restricting the user's ability to make changes in the OpenWebstart Settings? OpenWebstart will be deployed in a customer location; installed by system administrators. It is OK for these admins to have full control over the settings. The end-users, however, should be limited...

We are interested in OpenWebStart, but puzzled that the PersistenceService has not been implemented. Our app uses this service to save a small number of user preferences values (a properties file would be fine). Is there a recommended alternative to this functionality? Will PersistenceService be imp...
