Passing an entire file to JVM arguments

Question

I have several systems that all need to load the same properties to the JVM. I can use the -D flag to load one property at a time, but i am looking for something that will load

Answer 1

Some options:

1. Wrap your properties in your .jar file and then get your processes to read that properties file from getClass().getResourceAsStream()
2. Write a batch file to execute your Java processes, and either explicitly list the -D options, or create the command line dynamically.

I solve this problem normally by using Spring (used for other reasons too) and a PropertyPlaceholderConfigurer. That allows me to specify one or more locations for property files and modifies the Spring configuration in-place.
