Installing this plugin

This plugin is not shipped in any distribution. You must manually install it on an EasyEclipse distribution.

The dependent plugin Eclipse Java Development Tools must be present in the EasyEclipse distribution you use, or must be installed separately.

Getting started

To use Ganymede, your application must use Log4j. You can download the latest version of the log4j library from the Log4j website.

To start using Ganymede, here is a basic tutorial:

Create a new java project by selecting File > New > Project, then Java > Java project. Give the project a name, and click OK.

Create a new Java file by selecting File > New > File, call it Main.java. Paste the following code in the file, and save:

        import java.util.Properties;
        
        import org.apache.log4j.Logger;
        import org.apache.log4j.PropertyConfigurator;
        
        public class Main {
        public static void main(String argv[]) {
        Properties p = new Properties();
        p.setProperty("log4j.rootCategory", "debug,stdout,ganymede");
        p.setProperty("log4j.appender.stdout", "org.apache.log4j.ConsoleAppender");
        p.setProperty("log4j.appender.stdout.layout", "org.apache.log4j.PatternLayout");
        
        p.setProperty("log4j.appender.ganymede", "org.apache.log4j.net.SocketAppender");
        p.setProperty("log4j.appender.ganymede.remoteHost", "localhost");
        p.setProperty("log4j.appender.ganymede.port", "4445");
        p.setProperty("log4j.appender.ganymede.locationInfo", "true");
        
        PropertyConfigurator.configure(p);
        Logger logger = Logger.getLogger("main");
        logger.error("Test error.");
        }
        }

Add the Log4j library to the project, by selecting Project > Properties, then Java Build Path, and, in the Libraries tab, click add external Jars, locate the log4j jar file that you have downloaded and extracted, and click OK.
The project should compile (no error in the Problems view.
Run the project by selecting Run > Run As > Eclipse Application: an exception log4j:ERROR Could not connect to remote log4j server at [localhost]. We will try again later. java.net.ConnectException: Connection refused should appear in the Console view. This is correct since there's no server running.
Open, or display, the Ganymede Log4j View. push the button "Start Log4J server" on the upper right of the view.
Run the project again: it does not throw exception anymore. This is correct since the server is now running.
An event may be visible in the Ganymede Log4j View. If nothing appear, you must select the columns to display (no column is displayed by default)).

Select Window > Preferences..., then Ganymede Log4j View > Columns, click Add Column for a view values in the column drop-down. The log should be visible now.
