JFig update event not getting fired

[prateekjain jain]

Hi,
We are using jfig to load configuration files in a webapp deployed under tomcat 8.x. Everything is working fine and we are getting values as expected the only issue is once we change the files those are not getting reflected at runtime but if we restart the server then new values are available.

I have attached the sample code below which we are using to load config files and attaching listeners:

public class FileLoader implements JFigListener {

private List<File> configurationFiles;
private final static String DIR_TO_LOAD = FileUtils
        .getEvnProperty("ICEX_HOME") + "/conf/tenants/";
private Map<ICEXConfMapKey, JFigImpl> configMap = new HashMap<ICEXConfMapKey, JFigImpl>();
private static FileLoader loader;

public static FileLoader getInstance() {
    if(null==loader) {
        loader = new FileLoader();
    }
    return loader;
}

public  Collection<JFigImpl> getFigObjects() {
    return configMap.values();
}

public  void loadFile(File file) {
    ICEXConfMapKey key = makeICEXConfMapKey(file);
    JFigImpl fig = (JFigImpl)explicitLoad(file);
    configMap.put(key, fig);
}

public  JFigIF explicitLoad(File file) {
    JFigLocatorIF i = new JFigLocator(file.getAbsolutePath());
    JFigIF fig = null;
    try {
        fig = JFig.initialize(i);           
        fig.addConfigEventListener(loader);
    } catch (JFigException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    return fig;
}

public  Map<ICEXConfMapKey, JFigImpl> getConfigMap() {
    return configMap;
}

private  ICEXConfMapKey makeICEXConfMapKey(File file) {
    String tenantID = FileUtil.getTenantIDFromPath(file.getAbsolutePath());
    String moduleID = FileUtil.getModuleIDFromPath(file.getAbsolutePath());
    String fileName = file.getName();
    return new ICEXConfMapKey(tenantID, moduleID, fileName);
}

private void startup() {
    System.out.println("Starting to load configuration files");
    configurationFiles = FileUtils.getAllFilesFromDirectory(DIR_TO_LOAD);
    for (File f : configurationFiles) {
        if(ICEXConstants.MODULE_CONFIG_FILE_NAME.toString().equalsIgnoreCase(f.getName())) {
            System.out.println("Loading file " + f.getAbsolutePath());
            loadFile(f);
        }           
    }
    System.out.println("Configuration file loading done");
}

public static void main(String[] args) {
    System.out.println("hhkjhh");
    FileLoader.getInstance();
}

@Override
public void configurationUpdate(JFigEvent event) {
  System.err.println("Re-loading configurations");  
  Collection<JFigImpl> figs = getFigObjects();
  for(JFigImpl f : figs) {
      try {
        f.reprocessConfiguration();
    } catch (JFigException e) {
        System.out.println("Failed to reload configurations");
        e.printStackTrace();
    }
  }

}

private FileLoader() {
    startup();
}

}

It would be great if you have any pointers to this.

One other thing to consider. I generally have some sort of GUI interface or
web service on my applications that will call JFig initialize. I realize
that's not exactly what you're looking for but it will at least give you a
manual way to process the updated files.
