Are beans also destroyed with session invalidate()?

Hi,
I have a login JSP which creates a new session and puts the username into it.
My other JSP's also have page session=true, and each of them uses a bean. For example,
<jsp:useBean id="transferbean" class="transactions.transferBean" scope="session"/>
My logout JSP calls session.invalidate() and returns the user to the login page.
My question is- does the session.invalidate() call also destroy the transferbean data? The user will not close his browser window after logging out- he may choose to log in again as a different user. Will he have a new transferbean created for him, or will the previous transferbean data persist?
Thanks
Luanne

This is almost my case... I have a page called index.jsp which holds the session variables;
<jsp:useBean id="ValidationBean" scope="session" class="com.nbdesigns.beans.nbstore.Validation" />
<jsp:useBean id="OrderBean" scope="session" class="com.nbdesigns.beans.nbstore.Order" />If you start to shop, the orderbean holds your order. When you checkout you have to register or log in, in both cases the cart will be deleted.
All pages are included in the index.jsp with the <%include page="" %> tag.
Any ideas why the editing of values in validationbean causes the values in orderbean to be deleted?

ViewExpiredException issue with session invalidate on IE9

Hi guys,
I have posted this on the ADF forum as well as I'm not sure of the root cause is JHeadstart related or not - but I thought I would check also here to see if anyone else has encountered this ...
I'm using JDeveloper 11.1.1.6 (JHeadstart 11.1.1.4.26) and having problems when calling "session.invalidate();" with my custom JhsAuthenticationFilter. If i log on and immediately log out (so no web.xml timeout which is set to 25 min) - The message shown on screen is
"Because of inactivity, your session is timed out and is no longer active. Click on OK to reload the page"
In the log files, the following error is thrown

<ADFLogger> <addContextData> Execute queryI have the web.xml parameter org.apache.myfaces.trinidad.CLIENT_STATE_MAX_TOKENS set to 15.
This ONLY happens when using IE9 - using Firefox or Chrome it's not a problem. I'm guessing something is trying to access the page def after the token for the view has already been removed as part of the session.invalidate() ?
How can I find out what the root cause is and why is this only a problem with IE and not Chrome or Firefox ?
Any help greatly appreciated !!
Cheers,
Brent

Brent,
I think it is best to make a very simple testcase without JHeadstart (you can cust and paste code from the jhs auth fillter as needed) and then attach your testcase to the post on JDev forum, or copntact Oracle support.
Looks like a browser-specific ADF bug to me.

Issue with session.invalidate() in OC4J

Ok, here's the thing- I've got a servlet that autogenerates
pages to the client via XSL; so far so good. However whenever
the login page is displayed, we would like to "logout" the
current user if there is one and start fresh, as it were. All of
our persistent data is stored via the user's session object so
we are doing something like this:
public void doGet( HttpServletRequest request) {
HttpSession session = request.getSession();
// Some misc. stuff happens here;
// Nothing is written to the session, however
if ( page == LOGIN_PAGE) {
session.invalidate();
session = request.getSession();
String info = session.getAttribute( "INFO");
As soon as we request the attribute, after performing the
session invalidation & re-obtaining a new session the system
bails with an IllegalStateException: Session invalidated
exception.
Note that the exact same code works under the Sun Reference
Implementation (Apache Groups Tomcat 4.0) and is pretty much
verbatim from Jason Hunter's book Java Servlet Programming 2nd
Edition pg. 220.
Any ideas for a fix and/or workaround?

Hi
This works, here is a sample I've run on OC4J
public class SessionTestServlet extends HttpServlet
private static final String CONTENT_TYPE = "text/html";
HttpSession sess = null;
private static boolean login_page = true;
public void init(ServletConfig config) throws ServletException
super.init(config);
public void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException
sess = request.getSession(true);
try
if (login_page)
if(sess != null)
sess.invalidate();
sess = request.getSession(true);
sess.setAttribute("name","kalle");
catch(Exception e)
e.printStackTrace();
response.setContentType(CONTENT_TYPE);
PrintWriter out = response.getWriter();
out.println("<html>");
out.println
("<head><title>SessionTestServlet</title></head>");
out.println("<body>");
out.println("<p>Session: "+ sess+"<p>Name: "+
sess.getAttribute("name"));
out.println("</body></html>");
out.close();

Portlet question- session.invalidate()- with weblogic

Guys:
Has anyone had a issue with session.invalidate() using weblogic 8.1.
we have vignette and weblogic 8.1.
the problem i have noticed is session.getId retunrns a extra timestamp string in the end. And i am thinking since this changes the entire sessionid, it does not get invalidated. I tried adjusting the weblogic.xml's idlength session-param to 52 but this still happens after that. can anyone suggest any insights. i am unable to kill the session and hence the user is always logged in. the only way is to close to broswer window.
session id:

Everything works fine.
Environment : JBoss as the App Server.
Any help appreciated.

Hi Shailesh,
Thank you for the reply.
I checked the JCO's and everything is working fine.
And to be more clear.
I have the same application in 2 roles and in ESS role the application is working fine but the user in discussion is an external user and we have config in place for externals.
In XYZ role where the application is not working we created a new role to satisfy the authorizations. which are same in dev and QA. the application for the user with same authorization is working fine in dev but the same is not working in QA.
Any other inputs will be helpful.
Thanks & Regards,
Pramod

Spring framework - Error with session scoped Beans

Hello guys,
I'm trying execute my Java Application inside Netweaver Application Server, but I'm having problems with serviceBeans with scope session. Anyone have already used Spring with session scope?
Thanks,
Cleiton.

After many attempt, when I declared the bean with <aop:scoped-proxy /> it works, however it could cause performance problem. I don't need refer this bean by another singleton bean, i did a wrong configuration in order to make a work a round...
When I run my application on tomcat server, the DWR starts perfectly the "session scope bean form IOC container", but in the WEBAS maybe it's running in other thread. Is it possible?
Anyone had a problem like this?
I got a detailed error with log4j,

Does calling session.invalidate() also removes all the session attriutes?

Hi,
I want to know whether calling session.invalidate() also removes any objects in the session attributes.or we have to explicitly remove objects from the attributes.
I want to know this because my application is having some memory related problems. In my application when a user logs in we put many String objects int the session using session.setAttribute.
Now when the user logs out we call session.invalidate() .
Will these String objects occupy memory (i.e. will they be garbage collected ) after I call session.invalidate() ?
or
I have to explicitly remove all the session attributes programmatically?
Any assistance would be of great help.
Thanks & Regards,
Nirmal

Sigh. The invalidate dereferences all attributes from the current session. If the object doesn't have any other references (servlets? filters? listeners? whatever) then it will be eligible for GC. The object i.e the String objects does'nt have any remaining references after I nullified the arrayList (which was the one and only refeferencing the String Objects).
There isn't any servlet, filter, no other entity that is referencing the arraylist once the user's session is invalidated.
But still when I take the heap dump I'm gettingt those String objects in the heap.........
Once a user logs off we call his/her session.invalidate() and we don't want any of his/her arrayList (containing String objects) in the memory anymore.
Please tell me according to you what should be done in order to get rid of the unwanted String objects in the heap, beside my silly lines of code.
I've load tested the application using jmeter (say for 100 users) and for each of the users the String objects(contained in ArrayLIst) stored in the session are still available even though we called session.invalidate() for each of the user.
This is a major concern for memory related problems that we people are facing here.
Any help would be of great ......
Thanks & Regards,
Nirmal

Session timeout and session.invalidate() -- are they the same?

I was just wondering when a session timeout occurs (either by setting the session-timeout in web.xml or the server's default timeout), is the session automatically invalidated? Or should we call setMaxInactiveInterval() instead? Or is calling session.invalidate() the only way to invalidate a session?

Hello all,
Both are same in terms of functionality, but if you use both of them like
1: You specified the tag sessionTimeout and
2: in your program the session.maxInactiveIntervalTime( value ) here if the value is(we gave it in terms of seconds like for 40 minutes we give 2400) then the program code will override the value previously set in web.xml

Hey renie1515,
Thanks for using Apple Support Communities.
When you download past purchases on an iOS device or computer, that device or computer becomes associated with your Apple ID. This article describes how to manage these associations.
iTunes Store: Associating a device or computer to your Apple ID
http://support.apple.com/kb/ht4627
Once a device or computer is associated with your Apple ID, you cannot associate that device or computer with another Apple ID for 90 days.
Note: Removing a device from your Apple ID does not override the 90-day timer. You must wait 90 days from the day the device was first associated with your Apple ID before it can be associated with another Apple ID.
Have a nice day,

Hi I have the old photo shop elements 10 on my computer and want to update and was wondering what the differences between photoshop, lightroom and photoshop elements are?
Also when I upgrade does it have to be with a monthly membership or can I just purchase the product out right like you use to be able?

You cannot "update" from what you have to any of the applications you mention. It will have to be a straight purchase or subscription at full price.
Photoshop is a professional level application that makes no apologies for its very long and steep learning curve.
Lightroom is all about volume, and very light editing.

We use a doc template to create a purchased part spec document and then save them as pdf formatted files. These part spec documents are also appended with the datasheets for these purchased parts. When we want to update/revise the document, is there a method, using Acrobat, to make those updates to the pdf, or must we go back to the doc template and basically generate a new document?
Also, our resulting pdf documents aren't searchable. How can we generate pdf documents that are searchable? I may want to search for a part value or name within the body of these pdf documents, but currently can't do that...very inconvenient.
Can you assist?

Not totally sure about the search issue. A lot depends on how you created the PDF and what is in the datasheets you attached (like are they graphics?). The doc portion should be searchable as long as you used print to the Adobe PDF printer or PDF Maker. For your use, it may be that the print is adequate. However, the result should be searchable (unless maybe you had a form with filled in fields and created the PDF with PDF Maker. I think the form data may be retained in form fields and the fields are not searchable. In that case, a print might be a better procedure. (it would help to know the versions of WORD and Acrobat as well as the exact process you used to create the PDF.)
If the appended data sheets do not change, then you might try opening the original PDF and then using Replace Pages to replace the file created from the DOC file.

Is something wrong with the new software update. My battery dies within 4 hours. There are also problems with my e-mail accounts. Can someone help me?

Have you attempted an iTunes restore and setting up as a new device? Sometimes battery life issues can be caused by corrupted iOS software.
