is commons-exec thread safe?
Is commons-exec thread-safe? I am asking because ProcessBuilder is not, as stated in http://docs.oracle.com/javase/7/docs/api/java/lang/ProcessBuilder.html "*Note that this class is not synchronized.* If multiple threads access a ProcessBuilder instance concurrently, and at least one of the threads modifies one of the attributes structurally, it *must* be synchronized externally."

[daemon] Can't start jvsc on OSX 10.8
Hello -- I'm trying to start tomcat 7.0.50 on my OSX 10.8 machine following the instructions here: http://tomcat.apache.org/tomcat-7.0-doc/setup.html#Unix_daemon Version 1.0.15 of the commons daemon was bundled with tomcat. I built jsvc with this command: sudo ./configure --with-java=/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home and then I'm trying to use the daemon.sh script to start the service. My catalina log file says: Cannot find any VM in Java Home /Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home Cannot locate JVM library file java_init failed Service exit with a return value of 1 So I passed the -debug flag to jsvc to see what's happening: sudo ./daemon.sh --tomcat-user _www --java-home /Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home start Output is pasted below. It's clear that the problem is that the layout of the directories is not what jsvc is expecting: /Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents> ls -l total 8 drwxrwxr-x 3 root wheel 102B Feb 13 09:31 MacOS/ drwxrwxr-x 15 root wheel 510B Dec 18 19:16 Home/ -rw-rw-r-- 1 root wheel 1.5K Dec 18 19:13 Info.plist Any help?

Conditional Configuration Keys
All, I searched around and could find an answer, I have a set of properties where I want to conditionally select them based upon environment variables. For example, I have the following set: schemas.default=DB schemas.perf=PERF schemas.qa=QA schemas.int=INT And I would like to do something to the effect of: If (env.variable == 'qa') schemas=QA else If (env.variable == 'perf') schemas=PERF else If (env.variable == 'int) schemas=int else schemas=DB The way I accomplished this today is that I created an AOP interceptor that does this work and when the clients request "schema" it does this logic. My preference would be to handle this during property loading time. Are there any extensions where I could do such a thing?

RE: Conditional Configuration Keys
Oliver, Thanks for that reference, and while that is somewhat helpful it means that for each environment, we still need a separate properties file for each of the environments and another one for the common stuff. Previously, we had accomplished this before by conditionally loading files based upon path within our XML file like: My hope was to find a way to do that a little bit more concisely within a single file or as I mentioned hooking into the property loading process.

I don't think that this can be much improved. If you only use properties files, an option could be using the include directive [1] in a clever way. Here you can use variables, too. There is also the possibility to set an IOFactory on a PropertiesConfiguration. This factory is used for creating an input stream to the file to read.
