Reading properties file in jar META-INF

[Rusty Enisin]

I have a jar file that has different configurations depending on which stage of development it is in. The build puts the right info in the jar in a properties file. I am having a hard time accessing the properties file if I put it anywhere else other that right next to the class that is using it.

I would like to put the properties file in the META-INF dir of the jar file. Here is the code from a method in a class in the jar. This works if the properties file is next to the class:

 
InputStream is = getClass().getResourceAsStream("system.properties");
Properties prop = new Properties();

if ( is != null ) {

try {
prop.load(is);
return prop.getProperty("someProperty");
}
catch ( IOException ioe ) {
ioe.printStackTrace();
}
}

I have tried "/system.properties" and "/META-INF/system.properties" but they did not work. Absolute paths work. But our production machines have different paths.

How do I access the properties file in META-INF?

Try this:

InputStream inputStream = this.getClass().getClassLoader().getResourceAsStream("META-INF/system.properties");

That did it. Thanks, Jaikiran!
