The preferred jvm vendor has to be specified as follows in the jnlp file:

Hi Richard, I cannot say why it is not working for you. However I tried the TLS1.3 sample given here https://blog.gypsyengineer.com/en/security/an-example-of-tls-13-client-and-server-on-java.html . This sample does not work with AO JRE 8 u 265 (the bundled JRE of OWS) but it works with AO JRE 8 u 27...

Hi I am not sure what steps you followed. I hope here is what you did: 1. Install OWS 2. Go to <OWS install dir>/jre 3. you can rename this to jre_8_u265 4. Install a JVM 8 u 272 or later on your machine 5. Copy JRE directory from that JVM to OWS install dir. 6. From command line >javaws <url of jnl...

As part of OWS installation there is a JRE directory under the installation directory. This JRE is used to start OWS and download the jnlp file. The current version is 8 u 265. You could replace this JRE with 8 u 272+. Can you please try this and report back if it solved your issue?

Thanks

Please have a look at viewtopic.php?f=21&t=180

Hi javac is irrelevant. For running an app specified in a jnlp file you need to specify in the jnlp which JRE you want to use run the app. OWS then looks for that JRE on your machine or tries to download it. You can specify using the itw-settings tool how OWS manages the JVM used to run the app. Ple...

Hi, Are you using the same Java class that you have attached in a post above? This class leads to StackOverflow as the logMsg method is called recursively. I had a look at your class. In my opinion you need to clean up its code. Here is my implementation of the class that will run both in applet mod...

Hi In the JNLP file for running as an application you still have: <applet-desc name="HelloWorldGuiApplet" main-class="HelloWorldGuiApplet" width="1024" height="768"> <argument>Hello world!!!!</argument> </applet-desc> Is this a copy+paste error? Changing it to...

Just for information the app works with Java 11 on Windows 64.
Just to confirm you are using 32 bit linux and JVM is 32 bit azul_11.0.7, is this correct?

Thanks

After downloading the "CN=thawte SHA256 Code Signing CA - G2" from Thawte and imported it, it works.

Just for information, in which JVM's certificate store did you import the above certificate, OWS's bundled JVM or the JVM that you use to run the app?

Thanks

Thanks for your suggestion to improve the speed. However, this will entail lot of change that will require quite some effort. Regret to say that due to the lack of resources we cannot undertake this task.

You could try for example

ows.jvm.manager.cache.dir=c:\\temp\\jvmcache

You could mount the drive on the server and give it a name like E: or some such. Is this possible for you?

> If i "initialize" the application from the vendor website it's working but only for me but not for the other user on the terminal sever (Windows server 2012 R2) > Can you please explain what do you mean by "initialize app from vendor website"? Do you have the Jnlp file? Does it...

What is your Operating System? You say that you are starting your jnlp with ITW from commanline. Are you starting as follows? javaws.bat somejnlpfile.jnlp This should start ITW and not OWS. You say that you have registered .jnlpx with OWS. This is effective when starting a jnlp file with dbl-click o...

Likely by mid-November.

Hello Steffen,

This will be fixed in v 1.3.0 to be released in November. The bundled JVM will be started with arg -Xms64m.

Thanks for reporting this issue.

Hi

Thanks for using OWS.

For running JavaFX apps with OWS please have a look at:

Hi I started investigating this by making a small sample. When I start javaws http://host/abc.jnlp it shows me the authentication dialog twice : once in stage 1 for downloading jnlp and second time in stage 2 when it starts the jnlp. After this it does not show Authentication dialog for jar files. A...

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...
