Hello Steffen, For running OWS using the bundled jre with a smaller memory footprint what you are doing is correct, i.e. specifying jvm args in javaws.vmoptions . For running the application using the preferred JVM with smaller memory footprint it is correct to specify appropriate jvm args in the jn...

You say it is working on some machines but not on some other machines. The cause is: Caused by: java.nio.file.AccessDeniedException: C:\Users\rboada\.cache\icedtea-web\jvm-cache\azul_11.0.7\c6e8a848-6334-4ce5-b06e-d8c2c9ba35b8\zulu11.39.15-ca-fx-jdk11.0.7-win_x64\bin -> C:\Users\rboada\.cache\icedte...

Thanks for reporting this problem. It is some problem with ServiceLoader which is not always reproducible.

We decided to fix it by doing away with the ServiceLoader.

We are making a bug fix release OWS 1.2.2. We will announce as soon as it is out.

Hi I presume you are using OWS 1.2.1 on Windows. There is an exception in the logs: [ITW-APP ][2020-10-08 16:23:08.707 MESZ][ERROR][sun.nio.cs.StreamEncoder.writeBytes(StreamEncoder.java:221)] Exception in thread "ows-pool-1" java.util.ServiceConfigurationError: com.openwebstart.jvm.localf...

I am not sure if 10.* is a valid wildcard spec for an IP address. May be you can try 10.*.*.*?

I did some search and found this: https://docs.microsoft.com/en-us/previo ... dfrom=MSDN

> I have update the JNLP file to <java version="11+" href="https://download-openwebstart.com/jvms.json" initial-heap-size="32m" max-heap-size="320m"/>. I set the link to OpenWebStart default URI. > The URL of JVM Server by default is https://download-openwebst...

Also if you notice in your LAN settings you have selected Automatically Detect Settings. It says this may interfere with Manual Setting and so must be disabled for manual setting to take effect. Please try your app after disabling it and see if it works as expected.

Yes right. I was going to ask you about Advance setting where you apply the proxy to a particular protocol.

Hi Thanks for using OWS. In case of System Proxy OWS will pick up the settings from the LAN settings presuming Windows OS. To understand your issue better can you please attach the screen shot of your LAN Settings: LanSettings.PNG Also please send the logs. I will try to reproduce your issue and inv...

Hi, OpenWebStart is based on IcedTeaWeb which is an implementation of JSR56 OWS derives its security features from ITW. Following are links to documentation: IcedteaWeb : https://github.com/AdoptOpenJDK/IcedTea-Web https://icedtea.classpath.org/wiki/IcedTea-Web Security in ITW : https://icedtea.clas...

Hi,

This dialog means that Codebase attribute is missing in the manifest of the Jar file.

If the URL from where the jars are downloaded is trusted then you could bypass the checks on manifest. Please see : viewtopic.php?p=480#p480

Hi, You have specified the location of JVM server in your JNLP file: <j2se version="1.6+" href="http://java.sun.com/products/autodl/j2se" Using OWS's itw-settings > JVM Manager you can see which JVMs can be used by OWS and also specify whether to allow use of JVM server from JNLP...

> What is the preferred way of specifying this permission? Does it always have to go to the main JRE java.policy file or do you recommend placing it into the java.policy in "C:\Windows\Sun\Java\Deployment\", or perhaps, something completely different? Thank you for your help! > Depends on ...

Hi, You say that you have <all-permissions/> in the jnlp file and yet you are getting "Denying permission: ("java.net.SocketPermission" "my-dev-server" "resolve")" . This is strange because, as we discussed, with all-permissions the app should have the permiss...
