Logger in Liferay is not working

I'm using Liferay 6.20 with a tomcat.

According to this post: Liferay: what is the default approach for logging in Liferay? I've added a logger to my basic portlet class like this:

package mypackage.katalog;

import java.io.IOException;

import javax.portlet.ActionRequest;
import javax.portlet.ActionResponse;
import javax.portlet.PortletException;

import com.liferay.portal.kernel.log.Log;
import com.liferay.portal.kernel.log.LogFactoryUtil;
import com.liferay.util.bridges.mvc.MVCPortlet;

/**
 * Portlet implementation class KatalogUslugPortlet
 */
public class KatalogUslugPortlet extends MVCPortlet {
    private static Log _log = LogFactoryUtil.getLog(KatalogUslugPortlet.class);

    @Override
    public void processAction(ActionRequest actionRequest,
            ActionResponse actionResponse) throws IOException, PortletException {

        testLogger();

        super.processAction(actionRequest, actionResponse);
    }

    private void testLogger() {
        System.out.print("SYSTEM_OUT!!!");

        _log.info("INFO!!!");
        _log.debug("DEBUG!!!");
        _log.error("ERROR!!!");
    }
}

And logs are not appearing neither in the console, nor in the tomcat logs. What could gone wrong?

The problem was not in the logger. My portlet was just drag and dropped into my site and I thought that processAction(...) was the method that was called after each site refresh. In fact it should have look use doView(...) method as follows:

@Override
public void doView(RenderRequest renderRequest,
        RenderResponse renderResponse) throws IOException, PortletException {

    testLogger();

    super.doView(renderRequest, renderResponse);
}

The Liferay logger does not work in this way, you can login with the Liferay admin, go to Admin -> Control Panel -> Server Administration -> Log Levels - > Add Category.

There add the category mypackage.katalog, and set the level All.

Now, when you go to the portlet, you will see all the logs. Remember, once you restart the server, you have to do this process again!
