Could not Deserialize the session data


Recently there was an issue with the session not getting invalidated upon logging out in adf page. we were using the following code to invalidate the session in the logout method


FacesContext fc = FacesContext.getCurrentInstance();
ExternalContext ec = fc.getExternalContext();
HttpServletRequest req = (HttpServletRequest) ec.getRequest();
HttpServletResponse res = (HttpServletResponse) ec.getResponse();
HttpSession ses = (HttpSession) req.getSession(false);
ses.invalidate();
res.sendRedirect(target);
fc.responseComplete();

with the above code the following exception was thrown to the user


java.lang.NullPointerException
 at oracle.adf.share.http.HttpUtil.getAttribute(HttpUtil.java:98)
 at oracle.adf.share.http.HttpSessionScopeAdapter.get(HttpSessionScopeAdapter.java:240)

the issue is solved using the solution given in this forum
https://cn.forums.oracle.com/forums/thread.jspa?threadID=663589

ie. we have to release the Datacontrol also to invalidate the session

...
ValueBinding vb = fc.getCurrentInstance().getApplication().createValueBinding("#{data}");
BindingContext bc = (BindingContext)vb.getValue(fc.getCurrentInstance());
DataControl dc = bc.findDataControl("DataControl");
dc.release(DataControl.REL_ALL_REFS);
..

Stop Blog Theft !!!


This is to inform that Mr. Saravanan of http://jdeveloperandadf.blogspot.com is stealing many blog contents without prior permission of the original authors. I am the victim along with others.

So I believe that all his blogs are stolen from some other blogs..
