Examples with ExternalContext jakarta.faces.context.ExternalContext used on opensource projects

Example 1 with ExternalContext

use of jakarta.faces.context.ExternalContext in project spring-framework by spring-projects.

the class FacesContextUtils method getSessionMutex.

/**
 * Return the best available mutex for the given session:
 * that is, an object to synchronize on for the given session.
 * <p>Returns the session mutex attribute if available; usually,
 * this means that the HttpSessionMutexListener needs to be defined
 * in {@code web.xml}. Falls back to the Session reference itself
 * if no mutex attribute found.
 * <p>The session mutex is guaranteed to be the same object during
 * the entire lifetime of the session, available under the key defined
 * by the {@code SESSION_MUTEX_ATTRIBUTE} constant. It serves as a
 * safe reference to synchronize on for locking on the current session.
 * <p>In many cases, the Session reference itself is a safe mutex
 * as well, since it will always be the same object reference for the
 * same active logical session. However, this is not guaranteed across
 * different servlet containers; the only 100% safe way is a session mutex.
 * @param fc the FacesContext to find the session mutex for
 * @return the mutex object (never {@code null})
 * @see org.springframework.web.util.WebUtils#SESSION_MUTEX_ATTRIBUTE
 * @see org.springframework.web.util.HttpSessionMutexListener

@Nullable
public static Object getSessionMutex(FacesContext fc) {
    Assert.notNull(fc, "FacesContext must not be null");
    ExternalContext ec = fc.getExternalContext();
    Object mutex = ec.getSessionMap().get(WebUtils.SESSION_MUTEX_ATTRIBUTE);
    if (mutex == null) {
        mutex = ec.getSession(true);
    }
    return mutex;
}

Example 2 with ExternalContext

use of jakarta.faces.context.ExternalContext in project rubia-forums by flashboss.

the class JSFUtil method createFeedLink.

/**
 * Creates feed link.
 *
 * @param type RSS/Atom. See FeedConstants
 * @param what Kind of the link. See available kinds in FeedConstants
 * @param id   Id - for kind FeedCostants.GLOBAL is ignored
 * @return String with proper address
 */
public static String createFeedLink(String type, String what, Integer id) {
    ExternalContext ctx = FacesContext.getCurrentInstance().getExternalContext();
    String url = ctx.getRequestContextPath() + "/feeds/" + type + "/" + what + (GLOBAL.equals(what) ? "" : "/" + id.toString());
    String urlParam = getContextPath();
    String urlType = "s";
    url += "?url=" + urlParam + "&urlType=" + urlType;
    return url;
}

Example 3 with ExternalContext

use of jakarta.faces.context.ExternalContext in project myfaces by apache.

the class FlashImpl method _isRedirectTrueOnPreviousRequest.

/**
 * Return true if setRedirect(true) was called on the previous request.
 * Precondition: doPrePhaseActions() must have been called on restore view phase.
 * @param facesContext
 * @return
 */
private boolean _isRedirectTrueOnPreviousRequest(FacesContext facesContext) {
    ExternalContext externalContext = facesContext.getExternalContext();
    Map<String, Object> requestMap = externalContext.getRequestMap();
    Boolean redirect = (Boolean) requestMap.get(FLASH_PREVIOUS_REQUEST_REDIRECT);
    return Boolean.TRUE.equals(redirect);
}

Example 4 with ExternalContext

use of jakarta.faces.context.ExternalContext in project myfaces by apache.

the class FlashImpl method setRedirect.

@Override
public void setRedirect(boolean redirect) {
    if (_flashScopeDisabled) {
        return;
    }
    // FIXME this method has a design flaw, because the only valid value
    // is true and it should only be called by the NavigationHandler
    // in a redirect case RIGHT BEFORE ExternalContext.redirect().
    // Maybe a PreRedirectEvent issued by the ExternalContext would be a good
    // choice for JSF 2.1.
    FacesContext facesContext = FacesContext.getCurrentInstance();
    ExternalContext externalContext = facesContext.getExternalContext();
    Map<String, Object> requestMap = externalContext.getRequestMap();
    // save the value on the requestMap for this request
    Boolean alreadySet = (Boolean) requestMap.get(FLASH_REDIRECT);
    alreadySet = (alreadySet == null ? Boolean.FALSE : Boolean.TRUE);
    // if true and not already set, store it for the following request
    if (!alreadySet && redirect) {
        requestMap.put(FLASH_REDIRECT, Boolean.TRUE);
        // save redirect=true for the next request
        _saveRedirectValue(facesContext);
    } else {
        if (alreadySet) {
            log.warning("Multiple call to setRedirect() ignored.");
        } else // redirect = false
        {
            log.warning("Ignored call to setRedirect(false), because this " + "should only be set to true by the NavigationHandler. " + "No one else should change it.");
        }
    }
}

Example 5 with ExternalContext

use of jakarta.faces.context.ExternalContext in project myfaces by apache.

the class FlashImpl method isKeepMessages.

/**
 * Returns the value of a previous call to setKeepMessages() from this
 * request. If there was no call yet, false is returned.
 */
@Override
public boolean isKeepMessages() {
    FacesContext facesContext = FacesContext.getCurrentInstance();
    Boolean keepMessages = null;
    if (facesContext != null) {
        ExternalContext externalContext = facesContext.getExternalContext();
        Map<String, Object> requestMap = externalContext.getRequestMap();
        keepMessages = (Boolean) requestMap.get(FLASH_KEEP_MESSAGES);
    }
    return (keepMessages == null ? Boolean.FALSE : keepMessages);
