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
