• X-Domain Cookies in iFrames

  - by John

  Hi Guys, I have a domain A.com which is my website. I want to allow the user to login and then I have embedded an iframe into domain B.com which attempts to grab the cookie from A.com to allow the user to be continued to be signed in. I can't seem to get this working in IE ? A new session gets set instead and the cookie is never retrieved. I have set a P3P policy ? Any ideas what I am doing wrong.

• NHibernate, each property is filled with a different select statement

  - by Eitan

  I'm retrieving a list of nhibernate entites which have relationships to other tables/entities. I've noticed instead of NHibernate performing JOINS and populating the properties, it retrieves the entity and then calls a select for each property. For example if a user can have many roles and I retrieve a user from the DB, Nhibernate retrieves the user and then populates the roles with another select statement. The problem is that I want to retrieve oh let's say a list of products which have various many-to-many relationships and relationships to items which have their own relationships. In the end I'm left with over a thousand DB calls to retrieve a list of 30 products. Thanks. I've also set default lazy loading to false because whenever I save the list of entities to a session, I get an error when trying to retrieve it on another page: LazyInitializationException: could not initialize proxy If anybody could shed any light I would truly appreciate it. Thanks. Eitan

• JAXWS and sessions

  - by Pace

  I'm fairly new to writing web services. I'm working on a SOAP service using JAXWS. I'd like to be able to have users log-in and in my service know which user is issuing a command. In other words, have some session handling. One way I've seen to do this is to use cookies and access the HTTP layer from my web service. However, this puts a dependency on using HTTP as the transport layer (I'm aware HTTP is almost always the transport layer but I'm a purist). Is there a better approach which keeps the service layer unaware of the transport layer? Is there some way I can accomplish this with servlet filters? I'd like the answer to be as framework agnostic as possible.

• How to make a database service in Netbeans 6.5 to connect to SQLite databases?

  - by farzad

  I use Netbeans IDE (6.5) and I have a SQLite 2.x database. I installed a JDBC SQLite driver from zentus.com and added a new driver in Nebeans services panel. Then tried to connect to my database file from Services Databases using this URL for my database: jdbc:sqlite:/home/farzad/netbeans/myproject/mydb.sqlite but it fails to connect. I get this exception: org.netbeans.modules.db.dataview.meta.DBException: Unable to Connect to database : DatabaseConnection[name='jdbc:sqlite://home/farzad/netbeans/myproject/mydb.sqlite [ on session]'] at org.netbeans.modules.db.dataview.output.SQLExecutionHelper.initialDataLoad(SQLExecutionHelper.java:103) at org.netbeans.modules.db.dataview.output.DataView.create(DataView.java:101) at org.netbeans.modules.db.dataview.api.DataView.create(DataView.java:71) at org.netbeans.modules.db.sql.execute.SQLExecuteHelper.execute(SQLExecuteHelper.java:105) at org.netbeans.modules.db.sql.loader.SQLEditorSupport$SQLExecutor.run(SQLEditorSupport.java:480) at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:572) [catch] at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:997) What should I do? :(

• What's the proper way to fork() in FastCGI ?

  - by eugene y

  I have an app running under Catalyst+FastCGI. And I want it to fork() to do some work in background. I used this code for plain CGI long ago: defined(my $pid = fork) or die "Can't fork: $!"; if ($pid) { # print response exit 0; } die "Can't start a new session: $!" if setsid == -1; close STDIN or die $!; close STDOUT or die $!; close STDERR or die $!; # do some work in background I tried some variations on this under FastCGI but with no success. How should forking be done under FastCGI?

• [SCORM 2004] the cmi.total_time parameter does not return anything.

  - by Nephila

  I am programming a SCORM 2004 product. I can update the session_time, it works. I can set the status (passed, failed, etc...) I also can get the cmi.location time. No problems! But I don't succeed atingt get the total time (cmi.total_time). I have tested on 2 LMS: On Ganesha the API.GetValue('cmi.total_time') is an empty string. On Moodle the API.GetValue('cmi.total_time') is just a "P". I do have the correct logs with correct session times. EDIT. I also try on cloud.scorm.com and cmi.total_time returns each time PT0H0M0S.

• Filtering with joined tables

  - by viraptor

  I'm trying to get some query performance improved, but the generated query does not look the way I expect it to. The results are retrieved using: query = session.query(SomeModel). options(joinedload_all('foo.bar')). options(joinedload_all('foo.baz')). options(joinedload('quux.other')) What I want to do is filter on the table joined via 'first', but this way doesn't work: query = query.filter(FooModel.address == '1.2.3.4') It results in a clause like this attached to the query: WHERE foos.address = '1.2.3.4' Which doesn't do the filtering in a proper way, since the generated joins attach tables foos_1 and foos_2. If I try that query manually but change the filtering clause to: WHERE foos_1.address = '1.2.3.4' AND foos_2.address = '1.2.3.4' It works fine. The question is of course - how can I achieve this with sqlalchemy itself?

• How to make pdb recognize that the source has changed between runs?

  - by user88028

  From what I can tell, pdb does not recognize when the source code has changed between "runs". That is, if I'm debugging, notice a bug, fix that bug, and rerun the program in pdb (i.e. without exiting pdb), pdb will not recompile the code. I'll still be debugging the old version of the code, even if pdb lists the new source code. So, does pdb not update the compiled code as the source changes? If not, is there a way to make it do so? I'd like to be able to stay in a single pdb session in order to keep my breakpoints and such. FWIW, gdb will notice when the program it's debugging changes underneath it, though only on a restart of that program. This is the behavior I'm trying to replicate in pdb.

• What are the possible causes of JasperException

  - by CitadelCSCadet

  I have a JSP that takes an Arraylist from the session object and removes the items from it. It seemed to be working fine and then out of nowhere when I navigate to that page, the page is blank. I checked the Tomcat log files and in catalina.out I am receiving a JasperException an it is showing it as being on a line with the following for(int i; i < agentItems.size(); i++) agentItems is the name of the ArrayList I am using. I have been debugging it and can't seem to figure out what the problem might be. I have read that a JasperException is sometiems thrown as a JSP's NullPointerException. Is this true or am I just completely overlooking the problem? I have the web application running on a local machine and a intermediate server for development in which both of them have had no trouble. Why could it be that only on this server it is giving me problems?

• Process for beginning a Ruby on Rails project

  - by Daniel Beardsley

  I'm about to begin a Ruby on Rails project and I'd love to hear how others go through the process of starting an application design. I have quite a bit of experience with RoR, but don't have that many starting from scratch with only a vision experiences and would appreciate the wisdom of others who've been there. I'm looking for an order of events, reasons for the order, and maybe why each part is important. I can think of a few starting points, but I'm not sure where it's best to begin Model design and relationships (entities, how they relate, and their attributes) Think of user use-cases (or story-boards) and implement the minimum to get these done Create Model unit-tests then create the necessary migrations and AR models to get the tests to pass Hack out the most basic version of the simplest part of your application and go from there Start with a template for a rails app (like http://github.com/thoughtbot/suspenders) Do the boring gruntwork first (User auth, session management, ...) ...

• Linq to NHibernate - How to include parent object and only certain child objects

  - by vakman

  Given a simplified model like the following: public class Enquiry { public virtual DateTime Created { get; set; } public virtual Sender Sender { get; set; } } public class Sender { public virtual IList<Enquiry> Enquiries { get; set; } } How can you construct a Linq to Nhibernate query such that it gives you back a list of senders and their enquiries where the enquiries meet some criteria. I have tried something like this: return session.Linq<Enquiry>() .Where(enquiry => enquiry.Created < DateTime.Now) .Select(enquiry => enquiry.Sender) In this case I get an InvalidCastException saying you can't cast type Sender to type Enquiry. Any pointers on how I can do this without using HQL?

• How to create a Appointment in a Shared Calendar (Sharepoint) with VBA (Macro)?

  - by Diogo K.

  I am actually trying to make an appointment from an excel spreadsheet. I have all the information of the appointment, like subject, body, start and end dates, I actually can create an appointment but only with my personal calendar in outlook. How do I copy/move/create an appointment in a shared calendar in a sharepoint server? I've tried: Dim apOL As Object Dim objFolder As Folder Dim cro As String Set apOL = CreateObject("Outlook.Application") Set oItem = apOL.CreateItem(olApItem) Set MAPISession = apOL.Session ... cro = "stssync://sts/?ver=1.0&type=calendar&cmd=add-folder&base-url=(MY SP SERVER)&list-url=%2FLists%2FCronograma%20%20%2Fcalendar%2Easpx&guid=%7B02717CEF%2D404F%2D482F%2DA131%2D5C3C245CD268%7D&site-name=Testes&list-name=Cronograma%20-" ... Set objFolder = MAPISession.OpenSharedFolder(cro, Null,Null,Null) It gives me the error "Type Mismatch" I'd try to get the objFolder as the Sharepoint Folder then later create an local appointment and then try an Item.Move objFolder Is it the correct way?

• In JSF, how to handle repeating over a list that mutates

  - by Jon

  Hello, In a JSF page, I am iterating over a list of items provided by a session-scoped backing bean. The list needs to be kept up-to-date, so it is replaced with a fresh list every X minutes by a thread (in a thread-safe way). On my page, for each item I provide some text inputs and an "Update" button. If the list is refreshed before I hit "Update", the update does not happen (which is my problem). I happen to be using a4j:repeat, but I think this could also apply to other methods of iteration, including using dataTables. Any thoughts on how I can do this in a non-hackish way? Thanks!

• HQL - row identifier for pagination

  - by anna.ruk

  Does anyone know if HQL has a keyword to identify rows such as ROWID or ROWNUM? I would like to implement pagination with HQL but I am not able to use .setMaxResult() or .setFirstResult() because I don't work with the session object directly and therefore don't use the Query object but simply create my query as a string and use the .find() method. I tried using LIMIT and OFFSET in my query, but HQL seems to be ignoring these keywords and is returning the whole result to me no matter what. I'm also not able to use Hibernate criteria because it does not have support for the "HAVING" clause that appears in my query. My last resort is to restrict the result set using the ROWNUM/ROWID keyword. Does anyone else have any other suggestions?

• jQuery-ajax call: async property is not working?

  - by user269386

  Hi, given to certain circumstances, I'm forced to keep page settings (Javascript-values) in the session and it has to be done right before leaving the page (I can't use cookies, since "pageSettings" can become quite large and localStorage is not an option yet ;) ). So this is how I tried it. However it seems that when I call the page directly again, the call of "http://blabla.com/bla" happens asynchronous, even though the async-attribute is set (I don't receive the settings of the previous call, but of the one before): $jQ(document).ready(function () { $jQ(window).unload(Main.__setSessionValues); }); var Main = { pageSettings: {}, __setSessionValues: function __setSessionValues() { $jQ.ajax({ type: "POST", async: false, url: "http://blabla.com/bla", data: { pageSettings: Object.toJSON(Main.pageSettings) } }); } }; Does anyone know what the problem might be? thanks in advance

• Spring & Hibernate EJB Events

  - by Miguel Ping

  Is it possible to define a spring-managed EJB3 hibernate listener? I have this definition in my persistence.xml: <properties> <property name="hibernate.ejb.interceptor" value="my.class.HibernateAuditInterceptor" /> <property name="hibernate.ejb.event.post-update" value="my.class.HibernateAuditTrailEventListener" /> </properties> But I would like to manage HibernateAuditInterceptor and HibernateAuditTrailEventListener with spring, so I can do some bean injection (ex: session-scoped bean) within these classes. Is this possible?

• Web framework recommendation for python (webservices, auth, cache, ...)

  - by illuminated

  Hi all, Googling for the past week, but cannot finally decide which python web framework would be right for me. The web app I'm about to develop would be almost completely "pure" html with js (jQuery). Server side would have to do the following: authentication session management caching web services (almost all the on page data would be pulled with jQuery through web services) secured web services (through some form of authentication; this is for remote accessing some of the web services though other web apps, desktop/mobile applications) If there is a good tutorial/guide/idea for how to do this in Django I would be most thankfull if someone could share it as I already have experience with it. The thing that made me start thinking about other frameworks is Django's built in ORM. I know I could swap it with SQLAlchemy, but wouldn't go down that road if I'm not sure all the rest of the requirements is supported. Thanks all in advance.

• Fluent NHibernate + multiple databases

  - by Pablote

  My project needs to handle three databases, that means three session factories. The thing is if i do something like this with fluent nhibernate: .Mappings(m = m.FluentMappings.AddFromAssembly(Assembly.GetExecutingAssembly())) the factories would pick up all the mappings, even the ones that correspond to another database I've seen that when using automapping you can do something like this, and filter by namespace: .Mappings(m = m.AutoMappings.Add(AutoMap.AssemblyOf().Where(t = t.Namespace == "Storefront.Entities"))) I havent found anything like this for fluent mappings, is it possible?? The only solutions I can think of are: either create separate assemblies for each db mapping classes or explicitly adding each of the entities to the factory configuration. I would prefer to avoid both, if possible. Thanks.

• help in security assignment

  - by scatman

  i have to write a program that sniffs network packets (part1-the simple part). and i have to update the program (part2) so that it will be able to terminate connections. the specific requirements are: construct raw packets by specifying data link layer and network layer information including appropriate source and destination MAC and IP addresses. These packets are intended to terminate the connection. To do so, you should used SOCK_RAW as the socket type to be able to set the header information by yourself. can anybody give me some ideas on the second part? should i hijack the session,apply a dos attack on one of the users?? all i need is some tips of how to terminate the connection. i am using c programming language. and this is a course assignment for the security course.

• Form Security (discussion)

  I'm asking for brain storming and sharing experience. Which method you are using for form submiting security ? For example , for block automatically sended POST or GET datas, i'm using this method : // Generating random string <?php $hidden = substr(md5(microtime()) ,"-5"); ?> <form action="post.php" .... // assing this random string to a hidden input <input type="hidden" value="<?php echo $hidden;" name="secCode> // and then put this random string to a session variable $_SESSION["secCode"] = $hidden; **post.php** if ($_POST["secCode"] != $_SESSION["secCode"]) { die("You have to send this form, on our web site"); }

• Hibernate object equality checking

  - by Sujee

  As far as I understand(correct me if I am wrong) Hibernate uses object reference to check the object equality. When Hibernate identifies that there are more than one objects attached to same DB record, it throws following exception. "a different object with the same identifier value was already associated with the session" My question is, does Hibernate use equal() method to check the object equality (The default equal method uses object reference)? If it is true, will overridden equal() method change the Hibernate behavior? Note: My question is not about the issues of implementing equal() or hashCode() methods in a Hibernate persisted object. Thank you.
