javax.faces.application.ViewHandler

faces-config.xml

public class CustomViewHandler extends ViewHandlerWrapper {  private ViewHandler wrappped;  public CustomViewHandler(ViewHandler wrappped) {    super();    this.wrappped = wrappped;  }  @Override  public ViewHandler getWrapped() {    return wrappped;  }  @Override  public String getActionURL(FacesContext context, String viewId) {    String url =  super.getActionURL(context, viewId);    return removeContextPath(context, url);  }  @Override  public String getRedirectURL(FacesContext context, String viewId, Map<String, List<String>> parameters, boolean includeViewParams) {    String url =  super.getRedirectURL(context, viewId, parameters, includeViewParams);    return removeContextPath(context, url);  }  @Override  public String getResourceURL(FacesContext context, String path) {    String url = super.getResourceURL(context, path);    return removeContextPath(context, url);  }  private String removeContextPath(FacesContext context, String url) {    ServletContext servletContext = (ServletContext) context.getExternalContext().getContext();    String contextPath = servletContext.getContextPath();    if("".equals(contextPath)) return url; // root context path, nothing to remove    return url.startsWith(contextPath) ? url.substring(contextPath.length()) : url;  }}
