Unable to load class net.sf.ehcache.store.DefaultElementValueComparator

[fstn fs, módosítva 8 év-val korábban]

Hi, I trying to get request user info by using

Map<string, object> userInfo = (Map<string, object>) request.getAttribute(PortletRequest.USER_INFO);
</string,></string,>

And I always have this stacktrace:

how can I disable this cache?


Thank you for reading

You don't want to disable the cache, you want to change your code so you access user info correctly, namely by invoking the UserLocalServiceUtil methods.

Thank you, it's work with

	FacesContext fc = FacesContext.getCurrentInstance();

		if (fc == null) {
			return null;
		}

		User user = null;
		ExternalContext externalContext = fc.getExternalContext();
		if (externalContext.getUserPrincipal() == null) {
			logger.info("current user is null");
		} else {
			Long id = Long.parseLong(externalContext.getUserPrincipal().getName());
			try {
				user = UserLocalServiceUtil.getUserById(id);
			} catch (PortalException ex) {
				logger.error("Can't get current User", ex);
			} catch (SystemException ex) {
				logger.error("Can't get current User", ex);
			}
		}
		return user;

FacesContext fc = FacesContext.getCurrentInstance();

Faces? Dude, if you're going to post a question about faces, get it in the right group. Answers can be totally different from general dev and there may be better answers for you elsewhere.

I've moved to the faces category for others to chime in...

I would recommend the following instead:

ThemeDisplay themeDisplay = (ThemeDisplay) externalContext.getRequestMap().get(WebKeys.THEME_DISPLAY);
User user = themeDisplay.getUser();
