Re: macOS file path to the response.varfile

In the OWS install dir "Command+Shift+." will show hidden directory ".install4j". You will find "response.varfile" there.

Re: JAX-WS and openJDK 11

with which version of JRE are you trying to run your Jnlp application? I have no experience or running JAX-WS app with OWS. However, if the specified jre version > 1.8 you might have to add some module vm args.

Re: everything working even with expired code signing cert

OWS is not responsible for the build and jar signing. OWS checks the jar signing only after downloading the jar. If a jar has problematic certificate such as expired/expiring/invalid certificate you will see a log entry:" Jar found at <path to jar in the cache> has been verified as SIGNED_NOT_O...

I cannot say why OWS does not work without knowing about your environment.

Re: deployment.jvm.arguments.whitelist

In the jnlp file you should specify:

Code: Select all

<java version="17"	java-vm-args="   --add-exports=java.desktop/com.sun.java.swing.plaf.motif=ALL-UNNAMED .. "
There should be '=' after --add-exports. There is no need of a whitelist entry for this arg.
