How to set system property?

Solution 1:

You can do this via a couple ways.

One is when you run your application, you can pass it a flag.

java -Dgate.home="http://gate.ac.uk/wiki/code-repository" your_application

Or set it programmatically in code before the piece of code that needs this property set. Java keeps a Properties object for System wide configuration.

Properties props = System.getProperties();
props.setProperty("gate.home", "http://gate.ac.uk/wiki/code-repository");

Solution 2:

System.setProperty("gate.home", "/some/directory");
