We added a new input field to specify the host in 1.1.8
It will be available early next week

We fixed the missing version for the upcoming 1.1.8 release.
It will be available early next week

if there is already a java8 installed then OWS is registered as an alternative. The easiest way you can change this by downloading a *.jnlp file. Then right click on the file and chose "open with other program..." In the popup select OpenWebStart and on the bottom check the checkbox "...

JVM Manager Panel : Cannot lockdown the following settings? Add local... Find local Deactivate/Remove The list of JVMs are stored in a different location as the rest of the settings. Currently there is no possibility to limit the user in manipulating the known JVMs. Cache Panel : Why keep "Lim...

So far we had no reports from users using Intel RMM.
On the other hand we have only little information about the applications which are launched wit OWS.
We do not collect any data from our users.

Do you see any error or warning in the logs (either OWS logs or Intel RMM logs)?

You can find the code here: https://github.com/AdoptOpenJDK/IcedTea-Web/tree/master/jnlp-api Currently there are no plans to publish such an API-jar. Openwebstart is aimed at applications based on Java 1.8 which can for one or the other reason not migrate to Java 11 at the moment. If your applicatio...

not sure, we use install4j and its update mechanism.
A quick glance at the documentation suggests that there is a way for doing unattended updates.

Yes, all files are read using the method Properties.load()

you are right. OWS is geared towards end user which have full control over their computer. I think it would be possible to add an option to force update. But since this is a very specific use case of yours we most likely will not prioritize this a feature request very high. There is always the possi...

Yes, you are right, the bundled JVM is only used for running OWS. One exception to this is if your JNLP contains an <applet-dec> instead of an <application-desc> then it is also run with the bundled JVM. No, we only build one bundle with an 1.8 Java included. But you can have a look inside the insta...

The proxy settigns are used to create a java.net.ProxySelector which is then registered as the default ProxySelector.
As such it is used for any URL connection.

It should work the same as oracle's java web start.
We currently have some issue when the main jar file is not in the root JNLP.
So try to avoid having the main jar in an extension

You could try to leverage lazy loading.
But this would still require you to list all possible plugins in the JNLP.

So maybe this is not the sufficient

no, it is generally discouraged to create a own classloader in a JNLP application.
We will release a new 3.0.0 candidate soon so please register for the newsletter to get informed

maybe try the 3.0.0-alpha1 version.
it has a completely new classloader implementation.

so your app has its own classloader?

Or how are you loading your "plugins"?

Hi, there is no default JVM. The cache.json is only used to store the location and the status of different JVMs available on the current computer. The JNLP file contains the information about the JVM required to run the application. OWS will then use the cache.json to find a suitable JVM. If none is...

As a hint: in the log files of the first stage you will see a line shortly before the end which starts with: "About to launch external with commands"
In this line you see all the arguments that OWS is passing to the JVM when launching your application

OWS does no magic. It is only a launcher for your application. In general a newer JVM can run code compiled for an older Java version. But be aware that Java may has changed behavior between 1.7 and 11. Deprecated methods have been removed and some more subtle changes may also be there. Very famous ...

yes, if the JDK (I think Oracle Java 8 is the only one) has the JavaFX included then the application should run without a dependency to the jfx jars
