  • Tomcat session stickiness in session replication

    - by rabbit
    Hi, I am having a 2 instance load balanced and session replicated tomcat 6.0.20 cluster. Should sticky_session be set to true or false for in memory session replication. http://tomcat.apache.org/connectors-doc/reference/workers.html mentions : Set sticky_session to False when Tomcat is using a Session Manager which can persist session data across multiple instances of Tomcat. where as /tomcat-6.0-doc/cluster-howto.html (Cluster Basics) mentions : Make sure that your loadbalancer is configured for sticky session mode.

  • Getting JSON data in PHP

    - by domagoj412
    I have a JSON data like this: { "hello": { "first":"firstvalue", "second":"secondvalue" }, "hello2": { "first2":"firstvalue2", "second2":"secondvalue2" } } I know how to retrieve data from object "first" (firstvalue) and second (secondvalue) but I would like to loop trough this object and as a result get values: "hello" and "hello2"...

  • Where do I put inline script in head with Zend Framework?

    - by Joel
    I'm reading the manual here: http://zendframework.com/manual/en/zend.view.helpers.html but I'm still confused. I have a script in my head that I'm converting to the layout/view for the Zend MVC: <script type="text/javascript"> var embedCode = '<object data="http://example.com" type="application/x-shockwave-flash" height="385" width="475"><param name="src" value="http://example.com" /><param name="allowfullscreen" value="true" /></object>' </script> I first tried to add it is an external file like this (in layout): $this->headScript()->appendFile('js/embeddedVideo.js')->appendScript($onloadScript); <head> <?php echo $this->headScript(); ?> </head> Didn't really work, but anyway, I'm wanting to just add the script and not add it as an external file. How do I do that? Thanks!

  • Unset/Change Binding in WPF

    - by captcalamares
    How can I unset the binding applied to an object so that I can apply another binding to it from a different location? Suppose I have two data templates binded to the same object reference. Data Template #1 is the default template to be loaded. I try to bind a button command to a Function1 from my DataContext class: <Button Content="Button 1" CommandParameter="{Binding }" Command="{Binding DataContext.Function1, RelativeSource={RelativeSource AncestorType={x:Type Window}}}"/> This actually works and the function gets binded. However, when I try to load Data Template # 2 to the same object (while trying to bind another button command to a different function (Function2) from my DataContext class): <Button Content="Button 2" CommandParameter="{Binding }" Command="{Binding DataContext.Function2, RelativeSource={RelativeSource AncestorType={x:Type Window}}}" /> It doesn't work and the first binding is still the one executed. Is there a workaround to this? EDIT (for better problem context): I defined my templates in my Window.Resources: <Window.Resources> <DataTemplate DataType="{x:Type local:ViewModel1}"> <local:View1 /> </DataTemplate> <DataTemplate DataType="{x:Type local:ViewModel2}"> <local:View2 /> </DataTemplate> </Window.Resources> The View1.xaml and the View2.xaml contain the button definitions that I described above (I want them to command the control of my process flow). ViewModel1 and ViewModel2 are my ViewModels that implement the interface IPageViewModel which is the type of my variable CurrentPageViewModel. In my XAML, I binded ContentControl to the variable CurrentPageViewModel: <ContentControl Content="{Binding CurrentPageViewModel}" HorizontalAlignment="Center"/> In my .CS, I have a list defined as List<IPageViewModel> PageViewModels, which I use to contain the instances of my two View Models: PageViewModels.Add(new ViewModel1()); PageViewModels.Add(new ViewModel2()); // Set starting page CurrentPageViewModel = PageViewModels[0]; When I try to change my CurrentPageViewModel to the other view model, this is when I want the new binding to work. Unfortunately, it doesn't. Am I doing things the right way?

  • Access 2007 can I capture the "clicked" field using an OnClick event on a report?

    - by Aaron Quince
    In Access 2007 I want to be able to click on a name field in a report and call a separate report with personal information about the person who's name was clicked to start the event. This would be as an alternative to creating a subreport or including the subreport fields in the main report in the interest of saving space. How do I reference the value of the clicked field for use in a query called with the OnClick event? Thanks for your help.

  • What is the best schema design for child collection with a "primary" entity

    - by erg39
    Here is the scenario: You have a Persons table with a one-to-many relationship with an Addresses table, where one of the Address rows is the "primary" Address. Is it better in a normalized schema to Use a Persons.PrimaryAddressID to access the "primary" Address for a Person or Use an Addresses.IsPrimary bit column to reference the "primary" Address for a Person via Addresses.PersonID or Other and why?

  • Onclick not firing

    - by user320588
    I have a set of buttons on my master page (I have attached the code below) but no onclick event is being raised. I pulled the final page source and no onclick event was present. As you can see I tried a few different approaches to solve the problem. I am looking for a normal postback to the server but I am getting nothing when I click any of these buttons. What am I not doing? --Master --Master Code Behind Protected Sub Button_Command(ByVal sender As Object, ByVal e As CommandEventArgs) Handles btnCancel.Command, btnClear.Command Session("ButtonClicked") = e.CommandArgument End Sub Protected Sub Button_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnSave.Click, btnSubmit.Click Session("ButtonClicked") = CType(sender, Button).CommandArgument End Sub --Page Source

  • How to add a jar build by a project to the project in eclipse?

    - by Xetius
    I have a project which as part of the build process creates an XMLBeans jar file (stbSchemas.jar) which I want to include and reference in this project. Is this the best way to go about this (Single project) or should I have a child project which is built from the parent project? I am building this using Maven2 inside Eclipse. Is there a better way to do this so that I can maintain the integrity of the projects and stability of the builds.

  • Providing raw MP3/AAC data to Flex/Flash from a custom container

    - by Joonas Trussmann
    Having had a quick look at the Flex docs I can't seem to find any reference to providing audio content to be played from a custom (possibly encrypted - don't worry, it's not that evil) container format. Is this possible and if so, could someone point me in the right direction. Or if that's not possible, some way to hook into the disk/network (disk is much more important in this case) I/O of the sound playing mechanism to provide a supported container in memory from a custom wrapper.

  • Looking for RESTful Suggestions In Porting ASP.NET to MVC.NET

    - by DaveDev
    I've been tasked with porting/refactoring a Web Application Platform that we have from ASP.NET to MVC.NET. Ideally I could use all the existing platform's configurations to determine the properties of the site that is presented. Is it RESTful to keep a SiteConfiguration object which contains all of our various page configuration data in the System.Web.Caching.Cache? There are a lot of settings that need to be loaded when the user acceses our site so it's inefficient for each user to have to load the same settings every time they access. Some data the SiteConfiguration object contains is as follows and it determines what Master Page / site configuration / style / UserControls are available to the client, public string SiteTheme { get; set; } public string Region { private get; set; } public string DateFormat { get; set; } public string NumberFormat { get; set; } public int WrapperType { private get; set; } public string LabelFileName { get; set; } public LabelFile LabelFile { get; set; } // the following two are the heavy ones // PageConfiguration contains lots of configuration data for each panel on the page public IList<PageConfiguration> Pages { get; set; } // This contains all the configurations for the factsheets we produce public List<ConfiguredFactsheet> ConfiguredFactsheets { get; set; } I was thinking of having a URL structure like this: www.MySite1.com/PageTemplate/UserControl/ the domain determines the SiteConfiguration object that is created, where MySite1.com is SiteId = 1, MySite2.com is SiteId = 2. (and in turn, style, configurations for various pages, etc.) PageTemplate is the View that will be rendered and simply defines a layout for where I'm going to inject the UserControls Can somebody please tell me if I'm completely missing the RESTful point here? I'd like to refactor the platform into MVC because it's better to work in but I want to do it right but with a minimum of reinventing-the-wheel because otherwise it won't get approval. Any suggestions otherwise? Thanks

  • Why SQL2008 debugger would NOT step into a certain child stored procedure

    - by John Galt
    I'm encountering differences in T-SQL with SQL2008 (vs. SQL2000) that are leading me to dead-ends. I've verified that the technique of sharing #TEMP tables between a caller which CREATES the #TEMP and the child sProc which references it remain valid in SQL2008 See recent SO question. My core problem remains a critical "child" stored procedure that works fine in SQL2000 but fails in SQL2008 (i.e. a FROM clause in the child sProc is coded as: SELECT * FROM #AREAS A) despite #AREAS being created by the calling parent. Rather than post snippets of the code now, here is another symptom that may help you suggest something. I fired up the new debugger in SQL Mgmt Studio: EXEC dbo.AMS1 @S1='06',@C1='037',@StartDate='01/01/2008',@EndDate='07/31/2008',@Type=1,@ACReq = 1,@Output = 0,@NumofLines = 30,@SourceTable = 'P',@LoanPurposeCatg='P' This is a very large sProc and the key snippet that is weird is the following: **create table #Areas ( State char(2) , County char(3) , ZipCode char(5) NULL , CityName varchar(28) NULL , PData varchar(3) NULL , RData varchar(3) NULL , SMSA_CD varchar(10) NULL , TypeCounty varchar(50) , StateAbbr char(2) ) EXECUTE dbo.AMS_I_GetAreasV5 -- this child populates #Areas @SMSA = @SMSA , @S1 = @S1 , @C1 = @C1 , @Z1 = @Z1 , @SourceTable = @SourceTable , @CustomID = @CustomID , @UserName = @UserName , @CityName = @CityName , @Debug=0 EXECUTE dbo.AMS_I_GetAreas_FixAC -- this child cannot reference #Areas @StartDate = @StartDate , @EndDate = @EndDate , @SMSA_CD = @SMSA_CD , @S1 = @S1 , @C1 = @C1 , @Z1 = @Z1 , @CityName = @CityName , @CustomID = @CustomID , @Debug=0 -- continuation of the parent sProc** I can step through the execution of the parent stored procedure. When I get to the first child sproc above, I can either STEP INTO dbo.AMS_I_GetAreasV5 or STEP OVER its execution. When I arrive at the invocation of the 2nd child sProc - dbo.AMS_I_GetAreas_FixAC - I try to STEP INTO it (because that is where the problem statement is) and STEP INTO is ignored (i.e. treated like STEP OVER instead; yet I KNOW I pressed F11 not F10). It WAS executed however, because when control is returned to the statement after the EXECUTE, I click Continue to finish execution and the results windows shows the errors in the dbo.AMS_I_GetAreas_FixAC (i.e. the 2nd child) stored procedure. Is there a way to "pre-load" an sProc with the goal of setting a breakpoint on its entry so that I can pursue execution inside it? In summary, I wonder if the inability to step into a given child sproc might be related to the same inability of this particular child to reference a #temp created by its parent (caller).

  • How to impose maxlength on textArea in HTML , Javascript

    - by Rakesh Juyal
    I would like to have some functionality by which if i write <textarea maxlength="50"></textarea> <textarea maxlength="150"></textarea> <textarea maxlength="250"></textarea> it will automatically impose the maxlength on the textArea. If possible please donot provide the solution in JQuery. Note: This can be done if i do something like this: <textarea onkeypress="return imposeMaxLength(event, this, 110);" rows="4" cols="50"> function imposeMaxLength(Event, Object, MaxLen) { return (Object.value.length <= MaxLen)||(Event.keyCode == 8 ||Event.keyCode==46||(Event.keyCode>=35&&Event.keyCode<=40)) } copied from another thread But the point is I don't want to write onKeyPress and onKeyUp every time i declare a textArea.

  • Best practice with respect to NPE and multiple expressions on single line

    - by JRL
    I'm wondering if it is an accepted practice or not to avoid multiple calls on the same line with respect to possible NPEs, and if so in what circumstances. For example: getThis().doThat(); vs Object o = getThis(); o.doThat(); The latter is more verbose, but if there is an NPE, you immediately know what is null. However, it also requires creating a name for the variable and more import statements. So my questions around this are: Is this problem something worth designing around? Is it better to go for the first or second possibility? Is the creation of a variable name something that would have an effect performance-wise? Is there a proposal to change the exception message to be able to determine what object is null in future versions of Java ?

    What is the best way to download an mp3 file in java (on Android sdk)? http://developer.android.com/reference/java/net/package-summary.html Should I be using sockets? If so - what kind of "Stream" reader should I use? I have also read something about "intents" - is this something that is applicable here? I am also curious as to what should one do if connection gets interrupted - can I resume the download somehow or restart it? Any tips?

  • Django json serialization problem

    - by codingJoe
    I am having difficulty serializing a django object. The problem is that there are foreign keys. I want the serialization to have data from the referenced object, not just the index. For example, I would like the sponsor data field to say "sponsor.last_name, sponsor.first_name" rather than "13". How can I fix my serialization? json data: {"totalCount":"2","activities":[{"pk": 1, "model": "app.activity", "fields": {"activity_date": "2010-12-20", "description": "my activity", "sponsor": 13, "location": 1, .... model code: class Activity(models.Model): activity_date = models.DateField() description = models.CharField(max_length=200) sponsor = models.ForeignKey(Sponsor) location = models.ForeignKey(Location) class Sponsor(models.Model): last_name = models.CharField(max_length=20) first_name= models.CharField(max_length=20) specialty = models.CharField(max_length=100) class Location(models.Model): location_num = models.IntegerField(primary_key=True) location_name = models.CharField(max_length=100) def activityJSON(request): activities = Activity.objects.all() total = activities.count() activities_json = serializers.serialize("json", activities) data = "{\"totalCount\":\"%s\",\"activities\":%s}" % (total, activities_json) return HttpResponse(data, mimetype="application/json")

  • Dojo slider: update value dynamically

    - by xApple
    I am building an application where the user browses certain objects by scrolling and zooming. To change the zoom level I have successfully implemented a "dijit.form.HorizontalSlider" object. Every time the user changes the position of the silder, I can catch the "onChange" call and do something with that. However, the user can also zoom-in by double clicking inside the view zone, at which point the slider should change position automatically to reflect the new zoom level. My question is the following: what function or method should I call in my javascript to update the position of a dojo silder ? Here is the code that creates the silder object: var zoomSlider = new dijit.form.HorizontalSlider({ name: "zoom_slider", id: "zoom_slider", value: 0, minimum: 0, maximum: 19, discreteValues: 20, intermediateChanges: false, style: "width: 160px;", onChange: function(value) { brwsr.view.zoomTo(value); } }, "zoom_slider"); navbox_silder.appendChild(zoomSlider.domNode);
