In Resin 3.1, you need -J-DDEV_HOME. The top-level -D would only affect the watchdog manager.

I'm leaving this bug open in case it's possible to propagate the -D directly to the child without the -J.

Thanks for the explanation. The -D works in 3.1.0 and 3.1.1, and it's only the snapshot that this doesn't work. I also tried passing the value explicitly in <jvm-args> and that didn't get it picked up either.

Just confirmed that -D works in 3.1.1 but not 3.1.2 snapshot. The -J-D works in 3.1.1 and 3.1.2.

Assuming you intend to leave this change going forward, then you probably want to change the documentation in httpd.exe -h as well as http://www.caucho.com/resin-3.1/doc/resin-web-server.xtp#JDK%20arguments [^]

Thanks.

The -J-D will have to be the replacement. There doesn't appear to be a way to find out the -D arguments directly, and any heuristic propagation of System.getProperty values would introduce more uncertainty about the normal operation.

The arguments are available through JMX.
