Re: How to pass the --enable-preview parameter when using JSVC?
Yes, I did try -X--enable-preview, was passed via jsvc, but not in a meaningful or understandable way to java/tomcat.

Most Java-related binaries which call through to the JVM (e.g. javac) offer an option to pass JVM parameters using "-J[foo]". I don't see a mirror of that for jsvc unless maybe -X is intended to provide that facility. I would suggest that you ask the jsvc folks if they would consider adding a -J alias to -X if indeed that's what it's for. If -X is different than -J, then they should probably introduce a new -J option to support such things. - -chris -BEGIN PGP SIGNATURE- Comment: Using GnuPG with Thunderbird - https://www.enigmail.net/ iQIzBAEBCAAdFiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAl5zw8UACgkQHPApP6U8 pFgBnBAAmTZhyH/xSO2Nwtn0pYz3ddG1L6uvqfi1CVH0SxOZuf0MLzvxwtLAkgNU eqH72v8wXc0yBUm62Phphb/YtG2jhesOIKS2X8Tr33gYS9XNV8wkhfRMB/4/k295 2tkdydVgTezI3jXOG/ONA1kHVIEcuhxQWcdHJuYK2oFqGn559bHOj+SQB+FMPdLE BQNc5ZAFt20o05Q0Bx9Nsv69tlZPkaCc28DiQlinGFvPVqE4j/0M5VIxlc8uR3KR FbharaHsnMs0RIesec3+ITSyv7Vz16AQEPlEaNBuhSEN8e4S4Pk8xS7VGDbh/N7z J3pTWxi/VDoEunioqjr6KxIrzlSVF+KrNpIpJWUtT+k2if8CzvztkLDW9HoSdj3o GsMoSf1Pr4Jj5hHdr/MvmBthJ3d4BxD92iS1ADB2hinfu28mEPHiLRBWLd2GICOH zCKDTGfe9w+7y1kYcvz9Mf4nm0vnGE7/iaTZ3ZKJRLAHwJC6xQksA0S/OavmCsrx CtqHnzZoWZo2hXB4GoyK92qmy5iihfxyMHaQ5fADcQ7Kn+xPqv6DxEnASLqV/pj5 ZZCBfgJYAo/6IOYpte1MJ8AVAAwDvLIlsWcNpIF2Cfdu5vwHwh+9wSnM3eqGHznP 4FYdaRuuQIqKZS4VOdE6GTDzm2SloZGYWGx7fYuVlUaszflWzF0= =Z/9B -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
How to pass the --enable-preview parameter when using JSVC?
Hello, When I deploy my war it produces the below error message, telling me to pass the "--enable-preview". I can add the "--enable-preview" to my tomcat start.sh script dev environment to resolve the problem. However, if I launch the production tomcat using the jsvc binary (to bind to port 443 instead of 8443), the JSVC binary doesn't seem to pass the "--enable-preview" parameter. What must I do to allow JSVC to accept and pass the "--enable-preview" parameter? apache-tomcat-9.0.27 jdk-13.0.1 18-Mar-2020 15:38:27.659 SEVERE [main] org.apache.catalina.core.StandardContext.filterStart Exception starting filter [FrameSecurityFilter] java.lang.UnsupportedClassVersionError: Preview features are not enabled for com/marsh/div/rock/emp/FrameSecurityFilter (class file version 57.65535). Try running with '--enable-preview' (unable to load class ..) BUT then if I try to add --enable-preview to the production JSVC script environment: "Invalid option --enable-preview Cannot parse command line arguments" Thank you for any and all help!
