Executables in a war file

We'd like to ship some helper scripts (shell s开发者_如何转开发cripts) as part of an application war. Unfortunately it appears like our build system (maven) discard the permissions on all files and the scripts end up without the executable bit set.

Is it even possible to do that? Does the .war format support executable files? If yes: how could tell maven to keep the permissions/fix them somewhere in the process?

The problem is more likely that these bits are not supported in the underlying zip-format.

The execute bit does not need to be set, if you explicitly execute /bin/sh with the script name.

Also note that your program - which knows the location of the script - can invoke "chmod +x script.sh" before launching.

AFAIK, there is no way to set file permissions within a war/jar (this is however possible when using the Maven Assembly Plugin to create a binary distribution archive of your project, but this is another story).

So, I would either:

• Deliver (as a binary distribution) and run these script outside the webapp ~or~
• Read the files from the classpath, write them to the java.io.tmpdir directory, set the execution bit and then execute them from there ~or~
• Use @Thorbjørn solution (didn't try that but I guess it would work); I'm just wondering from where you execute these scripts.

You can also check and set the executable flag directly from your Java-Code. See http://docs.oracle.com/javase/6/docs/api/java/io/File.html#setExecutable%28boolean,%20boolean%29

Supply the executables outside of the WAR. Call them from within the WAR.
