• Session Bean returning another Remote Session Bean reference [JBOSS]

  - by mrlinx

  Hi all, I have a Stateless Session Bean in my JBoss Server that contains a function returning an instance of another Session Bean (this one is stateful). My problem arises because this returned object doesn't seem to keep its persistence model (the EntityManager is null). What is the right way to return from a Session Bean another Session Bean, keeping its remote "connection"?

• ASP.NET 'Session.Remove(key)' v/s 'Session(key) = nothing'

  - by Whiskey-Tango-Foxtrot

  I've seen developers use two approaches when they are done with a session object. 1) Session.Remove(key) 2) Session(key) = nothing What is the better approach of the two above? Does Session.Remove dispose the object stored automatically? Does the second approach depend on the garbage collector to actually free up the memory? Thanks.

• Reuse another ASP.NET session (set Session ID)

  - by queen3

  My problem is that when I open web application from Outlook in a separate IE window, the ASP.NET session is lost. This is (as described in several places) because in-memory cookie is lost. So it goes like this: User works with ASP.NET web application in Outlook, and this stores some info in ASP.NET session User clicks Print to open new IE window with print-ready data The new window has different ASP.NET session ID and can't access old data. I think, maybe, if I pass ASP.NET session ID to new IE window, I can somehow "attach" to that session? Tell ASP.NET that this is the one that I need to be current?

• ASP.Net Session data lost between pages

  - by Ananth

  Hi, i came across a weird behavior today w/ my web application. When I navigate from a page to another, I lose one particular session variable data. I'm able to launch the app in firefox and able to see that the session data is not lost. I use Response.Redirect(page2, false) to redirect to another page. Below code was used to track session variables System.IO.StreamWriter sw = new System.IO.StreamWriter(@"c:\test.txt", true); for (int i = 0; i < Session.Count; i++) { sw.WriteLine(Session.Keys[i] + " " + Session.Contents[i]); } sw.Close(); Can anyone help me in this? Any help is appreciated. ~/Ananth

• Session Mania: Content Catalog & Suggest-a-Session

  - by Justin Kestelyn

  As ably reported in the Oracle Technology Network blog, the Oracle Develop Conference's content catalog is now public (as are the catalogs for JavaOne and Oracle OpenWorld), meaning you can now explore technical sessions scheduled for the conf to your heart's content."But something's missing", you may tell yourself. "Where is my favorite subject, the one I happen to also be an expert on?" Well, there's good news for you, too: The Suggest-A-Session project has returned. It works thus: Submit a session idea via Oracle Mix and ask your colleagues, Oracle Mix community, friends and anyone else you know to vote for your session. (You must be an Oracle Mix member to vote.) Voting is open through June 20. For the most part, the top voted sessions will be selected for the Oracle Develop Conf (or Oracle OpenWorld) official agenda. See the FAQ for fine print.Apparently some people have already jumped into this loophole, including Oracle ACE Director Marco Gralike, who has "gone video" on us: Why wait? Suggest-a-session!

• Inexpensive Remote Assistance software?

  - by Jess

  Any recommendations for Remote Assistance software that does not require firewall modification for clients? To assist client with software problems and perform training, we currently use a tool called Remote Helpdesk to connect to their computers and guide them through the process. This tool was pretty cheap (~$400 onetime for 3 support staff), and worked great - the client's PC actually initiates the connection to us, so there's never any firewall issues (vs. Remote Desktop, VNC software, or many other similar tools). Unfortunately, the product doesn't work well with 64-bit O/S's and Vista in general (slows down by a factor of 10 or so). I am looking for alternatives that provide the same reverse connection capabilities to avoid firewall issues. The only solution I've found is WebEx's Remote Support, which is WAY too expensive ($449/month for us). Thanks for all the assistance!

• Problem closing MDI child window in Terminal Services/Remote Desktop Connection 7.0

  - by Justin Love

  I have one user whose computer just got updated to the 7.0 Remote Desktop Connection. Concurrently, she has started having a problem closing the MDI child windows in an old FoxPro application running on the remote server. We have two different servers, both 2003, running the same application, one locally and one at a remote office. Only the remote office server is giving trouble. It works fine for me, even when logging into her TS account. No other users have complained. The other day the same user experienced an error message (path not found for a path showing a localization placeholder) starting the RDC, fixed by reboot. I suspect she may have had RDC running during the 7.0 upgrade.

• How to set up cluster with SESSION replication in Coldfusion 10?

  - by user3427540

  I am not able to set up a cluster with session replication. I have successfully set up a cluster with sticky session. When googled I found a lot of links explaining the same issue, like http://cfmlblog.adamcameron.me/2012/11/problem-with-session-replication-with.html https://forums.adobe.com/thread/1238702?start=0&tstart=0 Does deselecting the sticky session auto enables the session replication? But no where i got a solutions. Anyone solved this problem?

• Remote Desktop Services create LAN and WAN user groups

  - by PHLiGHT

  I'm setting up one server with the gateway, server host and web access roles on it. I know that isn't ideal but I don't expect to have many simulatenous users. I want users to access remote desktop web access and connect to the server host via the gateway as outlined here which avoids opening 3389 to the internet. Users will be connecting from the LAN and the WAN. What I'm looking to do is to allow some users LAN access but not WAN access and added plus would be if security settings (such as no clipboard) would be different when accessing via the WAN. Is this possible? It seems all users can logon to remote desktop web access by default. They can't run the remoteapps once logged in though without the proper permissions. Can I prevent them from even logging into remote web access? Since they renamed it from terminal services to remote desktop services it has made my Googling a bit harder. Thanks!

• How does this Singleton Web Class persists session data, even though session is not updated in the p

  - by Micah Burnett

  Ok, I've got this singleton-like web class which uses session to maintain state. I initially thought I was going to have to manipulate the session variables on each "set" so that the new values were updated in the session. However I tried using it as-is, and somehow, it remembers state. For example, if run this code on one page: UserContext.Current.User.FirstName = "Micah"; And run this code in a different browser tab, FirstName is displayed correctly: Response.Write(UserContext.Current.User.FirstName); Can someone tell me (prove) how this data is getting persisted in the session? Here is the class: using System; using System.Collections.Generic; using System.Linq; using System.Web; public class UserContext { private UserContext() { } public static UserContext Current { get { if (System.Web.HttpContext.Current.Session["UserContext"] == null) { UserContext uc = new UserContext(); uc.User = new User(); System.Web.HttpContext.Current.Session["UserContext"] = uc; } return (UserContext)System.Web.HttpContext.Current.Session["UserContext"]; } } private string HospitalField; public string Hospital { get { return HospitalField; } set { HospitalField = value; ContractField = null; ModelType = null; } } private string ContractField; public string Contract { get { return ContractField; } set { ContractField = value; ModelType = string.Empty; } } private string ModelTypeField; public string ModelType { get { return ModelTypeField; } set { ModelTypeField = value; } } private User UserField; public User User { get { return UserField; } set { UserField = value; } } public void DoSomething() { } } public class User { public int UserId { get; set; } public string FirstName { get; set; } }

• PHP Session variable isset(..)=1 after session_start()

  - by Nicsoft

  Hello! I guess I am not understanding the scope of session variables, or the session itself, in PHP, hence this question: This is my code if(!session_id()==""){ echo "Getting rid of session"."</br>"; session_destroy(); } echo "Before session_start(): ".isset($_SESSION["first_date_of_week"])."</br>"; session_start(); echo "After session_start(): ".isset($_SESSION["first_date_of_week"])." ".$_SESSION["first_date_of_week"]->format("Y-m-d")."</br>"; The output is: Before session_start(): After session_start(): 1 2011-01-09 How come that when doing the isset(..) on the session variable it is set directly after starting the session, even though I haven't even used it or set it yet? It does, however, still have the same value as before. Also, session_id()="" since the if-clause is never triggered. I never kill the session, how come it is set to ""? I.e. I refresh the page and expects the session to still be alive. Using the isset(..) function is then pretty useless testing if it has been set already... Thanks in advance! /Niklas

• C# - Using a copy of Session-stored variables instead of reference

  - by Nir

  I have an asp:ImageButton with OnClick="Btn_OnClick". In Btn_OnClick I have this line: DataTable dtTable = (DataTable)Session["someSessionKey"] and dtTable is altered in the function. I've noticed that if the button's clicked more than once, the dtTable I take from the session contains the altered table, probably meaning dtTable is not a copy but a reference of the session variable. How can I alter a copy of Session["someSessionKey"], and not the actual value? Thanks!

• Remote Desktop, Host: 2008, Client: Windows 7, The remote computer requires Network Level Authentica

  - by deerchao

  Hi, today I accidently changed one option of Teminal Services, I checked "Allow connections only from computers running Remote Desktop with Network Level Authentication". After that, I can't connect to my server any more. The error says: The remote computer requires Network Level Authentication, which your computer does not support. But my client pcs(both home and at office) are running Windows 7, as far as I know, it shoud support NLA; And in About dialog of Remote Desktop Connection there says "Supports Network Level Authentication". My server is running Windows Server 2008, placed in IDC center; I could connect to it before I change the settings. All other sevices(like IIS, SQL Server) are running normally. For clients, I tried two PCs running Windows 7, and two virtual windows XP machine running in Virtual PC and Virtual Box, all of them gives the same error message. Is there a way I can make things right without go to IDC which is far away? Thanks.

• Identify remote desktop client software and OS when user logs into Windows 2008 R2 Remote Desktop

  - by georged

  We would like to detect what devices & what programs users are using to connect to the Windows 2008 R2 Remote Desktop. In particular, we would like to have an ability to detect the remote devices such as iPads, iPhones & Androids, identify the software used and allow these connections only for certain users based on combination of the client OS + software. If it can be done in powershell to be run as part of the logon script, that'd be ideal.

• Different types of Session state management options available with ASP.NET

  - by Aamir Hasan

  ASP.NET provides In-Process and Out-of-Process state management.In-Process stores the session in memory on the web server.This requires the a "sticky-server" (or no load-balancing) so that the user is always reconnected to the same web server.Out-of-Process Session state management stores data in an external data source.The external data source may be either a SQL Server or a State Server service.Out-of-Process state management requires that all objects stored in session are serializable.Linkhttp://msdn.microsoft.com/en-us/library/ms178586%28VS.80%29.aspx

• Starting a guest session from the login screen

  - by Odd-rationale

  I was wondering what is the best way to start the guest session from the login screen (GDM). Currently, I created a new user called 'ubuntu-guest' (has to be something other than 'guest'). Then added the following script to the Startup Applications. #!/bin/bash /usr/share/gdm/guest-session/guest-session-launch & /usr/bin/gnome-session-save --logout The problem with this method, is that when you log in as 'ubuntu-guest', you have to start up two gnome sessions: one for 'ubuntu-guest' and one for the actual guest account. Please let me know if you have any other better ideas. Thanks!

• Will Google crawl session based website

  - by DonShwep

  I have a website, it is split into 3 categories but using PHP its an all-in one kind of style. When a user chooses a category on the home page a session is set, this is then used to set the style and contents of the website. Would Googlebot and other bots be able to still scan my website? If a page is accessed and no session is set then the user is sent back to the home page. I have created special links, that set a session but go straight to the contact page. Even this page doesn't seem to be showing up. Any ideas if a sitemap with specially crafted links (to set the session) will help Google?

• Why can't WARs share session info?

  - by rvcoutinho

  I have seen several developers looking for a solution for this problem: accessing session information from a different WAR (even when inside the same EAR) - here are some samples: Any way to share session state between different applications in tomcat?, Access session of another web application, different WAR files, shared resources, Tomcat: How to share data between two applications?, What does the crossContext attribute do in Tomcat? Does it enable session sharing? and so on... From all I have searched, there are some specific solutions depending on the container, but it is somehow 'contrary to the specification'. I have also looked through Java EE specification without any luck on finding an answer. Some developers talk about coupling between web applications, but I tend to disagree. What is the reason one would keep WARs inside the same EAR if not coupling? EJBs, for instance, can be accessed locally (even if inside another EJB JAR within the same EAR). More specifically, one of my WARs handles authentication and authorization, and I would like to share this information with other WARs (in the same EAR). I have managed to work around similar problems before by packaging WARs as JARs and putting them into a singular WAR project (WEB-INF/lib). Yet I do not like this solution (it requires a huge effort on servlet naming and so on). And no solution has answered the first (and most important) question: Why can't WARs share session information?

• Remote Desktop - remote computer that was reached is not the one you specified

  - by Jim McKeeth

  We just setup some new Windows 2008 R2 servers and we are unable to Remote Desktop into them from our Windows 7 desktops. Remote desktop connects, but after we provide credentials we get: The connection cannot be completed because the remote computer that was reached is not the one you specified. This could be caused by an outdated entry in the DNS cache. Try using the IP address of the computer instead of the name. If we connect from Windows 7 to a machine not running Windows 2008 R2, or from a machine not running Windows 7 to the Windows 2008 R2 server, it works fine. Likewise if we connect to the Windows 2008 R2 server from Windows 7 via the IP address then it works fine (although that causes other problems later). I've only found one other mention of someone having this problem, so I don't think it is just our network. Any suggestions on how to connect from Windows 7 to Windows 2008 R2 via DNS? Both are 64-bit. Update: Turns out it does not need to be R2 to get the error. We have another server that is Windows 2008 R1 64-bit that also fails.

• hp ilo "remote console undefined"

  - by javapowered

  After upgrading my server (HP DL360p Gen8) to the latest ILO 4.30 I have such error What should I do and how to fix my problem? I do not have physical access to my server and so now I have no access at all (I still have ILO with no remote console) I think probably I should use "back-up" copy of ilo if it stored on server... or should I reupload some another ILO version? upd I've noticed that undefined link is "https:///html/undefined", i think I can try "hack" and just type direct link to "remote" page, but i do not have an address. It should be something like "https:///html/remote.html" Probably someone, who has access to ilo, can give me a link?

• Best Performing Remote Desktop Software for WAN

  - by Dave

  I've been tasked with connecting a computer in one of our branches in the midlands to one in south wales. We have been using windows remote desktop but find it too slow. The ADSL on the computer were connecting to is about 6Mb Download and 470Kb Upload so not majorly fast. That connection is also shared with about 10 other internet users. I'm trying to find out if the is any remote desktopn connecting software that performs better than the microsoft remote desktop software. Or, would i be better using a KVM over IP? I've looked into connecting the offices through BT's fiber optic but at £21k a year rental were trying to find a cheaper solution! Any help would be great. Thanks, Dave,

• Apple Remote Desktop and Screen Sharing

  - by jfm429

  We have a Mac OS 10.8.2 server that we want to be able to administer with Apple Remote Desktop. At the same time, we want normal users to be able to access their account screens (through background login) without being able to view the current screen. However, in order to enable this (by enabling the "normal" Screen Sharing option in System Preferences) Remote Desktop needs to be disabled. The question is - how can we run both Remote Desktop for administrators and VNC screen sharing for normal users while restricting normal users to logging in on a background window instead of viewing the front screen?
