I am trying to follow this instruction for running gate embedded.
It says: "System property gate.home should be set to the gate installation directory." ()
How do I do this?
Also when I try to run the example code of EmbeddedAnnie I get the following error: ( I don't know if it is related or not ).
Initialising GATE... GATE home system property ("gate.home") not set. Attempting to guess... Using "C:\Program Files (x86)\GATE-6.0" as GATE Home. If this is not correct please set it manually using the -Dgate.home option in yo ur start-up script Using C:\Program Files (x86)\GATE-6.0 as GATE home Using C:\Program Files (x86)\GATE-6.0\plugins as installed plug-ins directory.

You can do this via a couple ways.
One is when you run your application, you can pass it a flag.
java -Dgate.home="" 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", ""); System.setProperty("gate.home", "/some/directory"); For more information, see:
- The System Properties tutorial.
- Class doc for
System.setProperty( String key , String value ).
System.setProperty("gate.home", "/some/directory"); After that you can retrieve its value later by calling
String value = System.getProperty("gate.home"); For JBoss, in standalone.xml, put after .
<extensions> </extensions> <system-properties> <property name="my.project.dir" value="/home/francesco" /> </system-properties> For eclipse:
1You need the path of the plugins directory of your local GATE install. So if Gate is installed in "/home/user/GATE_Developer_8.1", the code looks like this:
System.setProperty("gate.home", "/home/user/GATE_Developer_8.1/plugins"); You don't have to set gate.home from the command line. You can set it in your application, as long as you set it BEFORE you call Gate.init().
