The short answer is "no". For reasons including security and platform-portability (Macintosh computers prior to OS X did not have environment variables, as I understand), the Java platfom does not support reading environment variables. However, the JRE has a mechanism for passing these properties over the command line, but I'm not totally sure whether they work the same way as the .properties file. I've been meaning to try it out, just haven't found the time yet. I think that if you run
java -DCatalogManager.catalogs=$HOME/cvs/xml/catalog.xml ... the JRE will use this property assignment rather than what's in the CatalogManager.properties file. Since the OS is doing the environment variable substitution, there aren't any issues on the Java end. Again, I'm really just guessing on this. I haven't hunted through the Java documentation to see how the entire property mechanism works, but I think this will work. The naming scheme may be different, though.

Is there some way to use environment variables in the catalogs properties of a CatalogManager.Properties file? Ie. something like this: catalogs=$HOME/cvs/xml/catalog.xml ? Thanx! - Steinar
