How to determine the locale within alfresco

I have a java class represents the list of value and i need to enforce the locale within it.

How can i determine the locale ?

The following class displays Constraint value/label for a content model.

package com.ds.ui.constraints;

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import java.util.ResourceBundle;  
import javax.faces.context.FacesContext;
import javax.faces.model.SelectItem;
import org.alfresco.repo.dictionary.constraint.ListOfValuesConstraint;
import org.apache.log4j.Logger;
import com.ds.ui.bean.dialog.util.BeanUtil;

public class PositionPermissionsConstraints extends ListOfValuesConstraint
    implements Serializable {

public void initialize(){
    LOG.debug("PositionPermissionsConstraints Initializer");
    super.setCaseSensitive(false);
    preparePermissionList();
}

public void preparePermissionList(){
    ResourceBundle bundle = null;   
    if(FacesContext.getCurrentInstance() != null){
        if(FacesContext.getCurrentInstance().getExternalContext().getRequestLocale() != null)
        bundle = ResourceBundle.getBundle(BeanUtil.RESOURECE_BUNDLE,
                FacesContext.getCurrentInstance().getExternalContext().getRequestLocale());
    }
    else
        bundle = ResourceBundle.getBundle(BeanUtil.RESOURECE_BUNDLE);

    List<String> av = new ArrayList<String>();
    av
    .add(PositionPermissionsConstraints.
            CREATE_ORGANIZATION_PERMISSION);
    this.allowedLabels
    .add(bundle.getString(CREATE_ORGANIZATION_PERMISSION));
    av
        .add(PositionPermissionsConstraints.
                UPDATE_ORGANIZATION_PERMISSION);
    this.allowedLabels
    .add(bundle.getString(UPDATE_ORGANIZATION_PERMISSION));

        .add(PositionPermissionsConstraints.
                DELETE_ORGANIZATION_PERMISSION);
    this.allowedLabels

If you're running in a WebScript, then I18NUtil is what you want. The method public static Locale getLocale() on it will return the locale for the currently running webscript
