  • Google app engine sessions now supported???

    - by user246114
    Hi, I thought google app engine did not support sessions (last time I checked was a few months ago). Now I was searching again for it and saw this: http://code.google.com/appengine/docs/java/config/appconfig.html#Enabling_Sessions says it supports: javax.servlet.http.HttpSession does this mean we have servlet session support now? If so, does anyone have an example of using this? I wanted to create my own User class and support user login and session management (I know app engine already supports this for google users, but wanted my own users for various requirements) Thanks!

  • JSF Rendering Issue (Page getting cached)

    - by Shamik
    I am facing a strange issue with JSF. I have developed one controller and bind it to request scope. I need to access one jsf page like http://localhost:8080/selectRule.jsf?type=A and on the same IE session I want to issue another request like http://localhost:8080/selectRule.jsf?type=B as we can see, only the type is changing here. This is why I have a ruleController bound to request scope, so that every request, creates the controller and pulls out the data depending upon type. I have a private HtmlSelectOneMenu choices item in the page. What I see is, somehow only once in the session the getChoices() is getting called. This is what I see For each url, one new ruleController object is getting created. Only first time getChoices() are called. In the subsequent time, if I change the URL in the web browser, the getChoices() method are not getting called though a new controller is getting created. Note: I am using JSF 1.1

  • Is it possible to get Logged in user Non Restricted token from a service on Vista?

    - by coolcake
    Hello All, I need to create a process with integrity level high, so that it can do all the administrative tasks. But the created process should run in the current logged in desktop i.e. it should not run in session 0. By default only administrators will log on to the console. The service should launch the process, as service is running in session 0 and system account. Can it any how get the non restricted token and use it in CreateProcessAsUser, so that the process created does have integrity level of high or system. Is it possible? One more thing is i should get the non restricted token with out prompting for user name or password of the logged in user. Thanks

  • Strange behaviour of Android debugger in Eclipse when using Camera for preview.

    - by Buzzy
    Hi, I have an Android application that uses a SurfaceView subclass and Camera object to preview images before capture. Once I capture an image, I stop the preview and release the camera. Execution stops at any breakpoint after this. However, apart from the "Suspend" and "Terminate" icons, the rest are disabled. This is strange because the "Debug Current Instruction Pointer" is clearly at the said breakpoint and execution is already suspended. I can't perform any debugging operations and have no option but to terminate the session. Sometimes (very rarely), the session terminates by itself. I can confirm that this odd behavior takes place only after I preview the camera capture. I am fairly new to Android development. Is there some obvious mistake I am making? Any help would be highly appreciated.

  • Where do I put the Current user query so as to not repeat per controller?

    - by Kevin
    I have a standard query that gets the current user object: @user = User.find_by_email(session[:email]) but I'm putting it as the first line in every single controller action which is obviously not the best way to do this. What is the best way to refactor this? Do I put this as a method in the Application controller (and if so, can you just show me a quick example)? Do I put the entire @user object into the session (has about 50 columns and some sensitive ones like is_admin)? Or is there another way to remove this kind of redundancy?

  • Preventing dictionary attacks on a web application

    - by Kevin Pang
    What's the best way to prevent a dictionary attack? I've thought up several implementations but they all seem to have some flaw in them: Lock out a user after X failed login attempts. Problem: easy to turn into a denial of service attack, locking out many users in a short amount of time. Incrementally increase response time per failed login attempt on a username. Problem: dictionary attacks might use the same password but different usernames. Incrementally increase response time per failed login attempt from an IP address. Problem: easy to get around by spoofing IP address. Incrementally increase response time per failed login attempt within a session. Problem: easy to get around by creating a dictionary attack that fires up a new session on each attempt.

  • Two Persistence Units, Two entityManagerFactory(s), SPring, JPA, Hibernate

    - by sebajb
    I am using Two entityManagerFactory{1,2} based on two persistence units, autowired through spring, hibernate, with resource local. My DaoImpls are configured with the PersistenceUnit(unitName='...') according to the unit needed. I was under the impression that using them with the unitName specified would allow me to use x number of PUs without problem but I still get: expected single matching bean but found two: [emf1, emf2]. Am I missing some other configuration?

  • Visual Studio stops debugging with no errors unexpectedly

    - by HeavyWave
    I am debugging a project and Visual Studio stops debugging and closes the program on the following line with no exceptions or error messages (I have enabled notifications for any thrown exceptions in options): var query = Session.Linq<RSS>() .Where(x => x.LastRetrieved <= date || x.LastRetrieved == null) .Where(x => x.Moderated); Where Session.Linq refers to LINQ2NHibernate. Anyway, the question is: what are the possible reasons for such behavior? Tested both on VS 2010 and 2008 - they behave identically just falling out of debugging.

  • Help with a cryptic error message with KGDB - Bogus trace status reply from target: E22

    - by fortran
    Hi, I'm using gdb to connect to a 2.6.31.13 linux kernel patched with KGDB over Ethernet, and when I try to detach the debugger I get this: (gdb) quit A debugging session is active. Inferior 1 [Remote target] will be killed. Quit anyway? (y or n) y Bogus trace status reply from target: E22 after that the session is still open, I can keep going on and on with ctrl+d, and the debugger doesn't exit. I've searched for that message in google and there are just 5 results (and none of them are useful :-/ ). Any idea of what could it be and how to fix it?

  • Force Hibernate To Save A Specific POJO

    - by user1695626
    I have some code calling a webservice and it returns an id. I am saving this id in the database using hibernate. I have a filter that opens the session and commits it, rolling back when any exception occurs within the contained code. Since there is no way to get back the id returned by the webservice I would like to save this in the database EVEN if there is an exception that occurred later on in the code. Is there anyway to do this using the same session?

  • NHibernate cascade and generated guid ids - why are they not generated for the children on save?

    - by asgerhallas
    I do the following: var @case = new Case { Name = "test" }; // User is persistent and loaded in the same session User.AddCase(@case); // sets @case.User = User too Session.Update(User); response.CaseId = @case.Id; The cascade on User.Cases is set to All. But @case.Id is not set until the transaction is committed. Is that expected behavior? I would very much like to get the Id before committing. Can it be done?

  • Send invitation to any user of google chats (is it possible?)

    - by Gizzo
    Hi I try to realize simple code on perl which should just get/send messages from/to gtalk accounts. I use Net::XMPP::* modules. All works just fine for users, who are my friends (in my "buddy" list). But i can't send message to unknown user. I know, that for this case i must send an invitation first, but Net::XMPP::* don't provide this possibility. There is only one way to invite person - construct my own xml according to "XEP-0155 Stanza Session Negotiation" protocol. But this doesn't work correct. When i send xml to server, it returns error "service-unavailable". I send: <message to='[email protected]'> <sxde xmlns='http://jabber.org/protocol/sxde' xmlns:sxde='http://jabber.org/protocol/sxde#metadata' session='0AEF4278DC4B6577' id='b'> <negotiation> <invitation> <feature var='http://jabber.org/protocol/whiteboard' /> </invitation> </negotiation> </sxde> </message> before my message. ANSWER: <message from='' to='[email protected]/TALKCDDCCE63' type='error'> <sxde id='b' session='0AEF4278DC4B6577' xmlns='http://jabber.org/protocol/sxde' xmlns:sxde='http://jabber.org/protocol/sxde#metadata'> <negotiation> <invitation> <feature var='http://jabber.org/protocol/whiteboard'/> </invitation> </negotiation> </sxde> <nos:x value='disabled' xmlns:nos='google:nosave'/> <arc:record otr='false' xmlns:arc='http://jabber.org/protocol/archive'/> <error code='503' type='cancel'> <service-unavailable xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'/> </error> </message> Maybe i lost smth or should send another info before (or after..) ? Or maybe there are another way to send message without any invitation? Thanks in advance

  • How can I set breakpoints in an external JS script in Firebug

    - by Manu
    I can easily set breakpoints in embedded JS functions, but I don't see any way of accessing extarnal JS scripts via Firebug unless I happen to enter them during a debug session. Is there a way to do this w/o having to 'explore' my way into the script? @Jason: This is a good point, but in my case I do not have easy access to the script. I am specifically talking about the client scripts which are invoked by the ASP.Net Validators that I would like to debug. I can access them during a debug session through entering the function calls, but I could not find a way to access them directly.

  • problem with TEMPORARY TABLE

    - by Z77
    Within PHP I do: 1.) A temporary table is created: CREATE TEMP TABLE new_table AS SELECT .... FROM ...; 2.) AFter that I want to use this table to create a shape file: shell_exec ("pgsql2shp .... -u username -P password ...); Separetly those two things work, but by creating a temporary table and after that using this table in pgsql2shp does not work. I pressume this is because temporary table duration is to the end of session. But to create shp file I need to use username and password what means new session starts and temporary table is dropped before I use it for shape creation. Any tip how to solve it? Thank you!

  • How to store currently logged on user in DB?

    - by stacker
    Using Seam 2.1.2 and JSF 1.2 I wonder how to store the users login name in the database. In plain JSF I would simply lookup FacesContext.getCurrentInstance().getExternalContext().getRemoteUser();in a backing bean and set the value into a persistent object. How can I achieve that the users name will be stored in the DB?
