  • Websphere CE issue in Eclipse EE

    - by Moev4
    I have downloaded the Websphere 2.1 App Server and verified that it works fine. I now wanted to use eclipse EE to manage it by adding the server to the server tab. Everything seems to work fine when going through the setup but when I go to start the server I get the error message: ERROR [GBeanInstanceState] Error while starting; GBean is now in the FAILED state: abstractName="org.apache.geronimo.framework/j2ee-system/2.1.4/car?ServiceModule=org.apache.geronimo.framework/j2ee-system/2.1.4/car,j2eeType=AttributeStore,name=AttributeManager" java.io.IOException: Unable to write manageable attribute files to directory /opt/IBM/WebSphere/AppServerCommunityEdition/var/config at org.apache.geronimo.system.configuration.LocalAttributeManager.ensureParentDirectory(LocalAttributeManager.java:573) at org.apache.geronimo.system.configuration.LocalAttributeManager.load(LocalAttributeManager.java:327) .... I was wondering if anyone had experience with this particular issue?

  • ASP.NET MVC : Good Replacement for User Control?

    - by David Lively
    I found user controls to be incredibly useful when working with ASP.NET webforms. By encapsulating the code required for displaying a control with the markup, creation of reusable components was very straightforward and very, very useful. While MVC provides convenient separation of concerns, this seems to break encapsulation (ie, you can add a control without adding or using its supporting code, leading to runtime errors). Having to modify a controller every time I add a control to a view seems to me to integrate concerns, not separate them. I'd rather break the purist MVC ideology than give up the benefits of reusable, packaged controls. I need to be able to include components similar to webforms user controls throughout a site, but not for the entire site, and not at a level that belongs in a master page. These components should have their own code not just markup (to interact with the business layer), and it would be great if the page controller didn't need to know about the control. Since MVC user controls don't have codebehind, I can't see a good way to do this. Update FINALLY, a good (and, in retrospect, obvious) way to accomplish this. using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; namespace K.ObjectModel.Controls { public class TestControl : ViewUserControl { protected override void Render(System.Web.UI.HtmlTextWriter writer) { writer.Write("Hello World"); base.Render(writer); } } } Create a new class which inherits ViewUserControl Override the .Render() method as shown above. Register the control via its associated ASCX as you would in a webForm: <%@ Register TagName="tn" TagPrefix="k" Src="~/Views/Navigation/LeftBar.ascx"%> Use the corresponding tag in whatever view or master page that you need: <k:tn runat="server"/> Make sure your .ascx inherits your new control: <%@ Control Language="C#" Inherits="K.ObjectModel.Controls.TestControl" %> Voila, you're up and running. This is tested with ASP.NET MVC 2, VS 2010 and .NET 4.0. Your custom tag references the ascx partial view, which inherits from the TestControl class. The control then overrides the Render() method, which is called to render the view, giving you complete control over the process from tag to output. Why does everyone try to make this so much harder than it has to be?

  • Is it OK to pass SQLCommand as a parameter?

    - by TooFat
    I have a Business Layer that passes a Conn string and a SQLCommand to a Data Layer like so public void PopulateLocalData() { System.Data.SqlClient.SqlCommand cmd = new System.Data.SqlClient.SqlCommand(); cmd.CommandType = System.Data.CommandType.StoredProcedure; cmd.CommandText = "usp_PopulateServiceSurveyLocal"; DataLayer.DataProvider.ExecSQL(ConnString, cmd); } The DataLayer then just executes the sql like so public static int ExecSQL(string sqlConnString, System.Data.SqlClient.SqlCommand cmd) { int rowsAffected; using (SqlConnection conn = new SqlConnection(sqlConnString)) { conn.Open(); cmd.Connection = conn; rowsAffected = cmd.ExecuteNonQuery(); cmd.Dispose(); } return rowsAffected; } Is it OK for me to pass the SQLCommand as a parameter like this or is there a better more accepted way of doing it. One of my concerns is if an error occurs when executing the query the cmd.dispose line will never execute. Does that mean it will continue to use up memory that will never be released?

  • How to raise a validation event from a key press

    - by flavour404
    Hi, I want to raise the: private void txtbox_startdate_Validating(object sender, System.ComponentModel.CancelEventArgs e) {} Function from a key leave event. The leave event looks like: private void txtbox_startdate_Leave(object sender, EventArgs e) {} The trouble is of course if I try and call it in this manner: txtbox_startdate_Validating(sender, e) An error is raised because in this case 'e' is an EventArgs whereas the validation function wants a System.ComponentModel.CancelEventArgs and so, how do I convert EventArgs to a System.ComponentModel.CancelEventArgs or create one so that I can call my validation function? Thanks, R.

In the constructor of the main window, I have the following code: public MainWindow([Dependency] IUnityContainer container) { InitializeComponent(); Cursor = System.Windows.Input.Cursors.Wait; Mouse.OverrideCursor = System.Windows.Input.Cursors.Wait; ForceCursor = true; //this.Cursor = System.Windows.Input.Cursors.AppStarting; // event subscriptions PresenterBase.EventAggregate.GetEvent<ModulesLoadedEvent>().Subscribe(OnModulesLoaded); } After all modules have been loaded, the following handler is invoked: private void OnModulesLoaded(EventArgs e) { allModulesLoaded = true; Mouse.OverrideCursor = null; Cursor = System.Windows.Input.Cursors.Arrow; } Problem is, I do not see this wait cursor. What I am missing here? FWIW, I got a hint from this post http://stackoverflow.com/questions/2078766/showing-the-wait-cursor TIA.

  • A good approach to db planing for reporting service

    - by Itay Moav
    The scenario: Big system (~200 tables). 60,000 users. Complex reports that will require me to do multiple queries for each report and even those will be complex queries with inner queries all over the place + some processing in PHP. I have seen an approach, which I am not sure about: Having one centralized, de-normalized, table that registers any activity in the system which is reportable. This table will hold mostly foreign keys, so she should be fairly compact and fast. So, for example (My system is a virtual learning management system), A user enrolls to course, the table stores the user id, date, course id, organization id, activity type (enrollment). Of course I also store this data in a normalized DB, which the actual application uses. Pros I see: easy, maintainable queries and code to process data and fast retrieval. Cons: there is a danger of the de-normalized table to be out of sync with the real DB. Is this approach worth considering, or (preferably from experience) is total $#%#%t?

The problem is that instead of making the computer look like its thinking, the program waits and then puts the X and O together at the same time. Can someone help me make it so that the program puts an X wherever i click AND THEN wait before it places an O? Edit: in case any of you are wondering, i realize that the computers AI is ridiculously dumb, but its just to mess around right now. Later on i will implement a serious AI..hopefully.

  • ASP.Net MVC 2 / EF 4 Reference Issue

    - by Eric J.
    My ASP.Net MVC 2 project references a Domain project where POCO business objects are defined and a Data project where EF 4 POCO persistence is implemented. Things were running well until I had a little fussiness with my version control provider (rollback to previous version left me with merge conflicts). Now, upon launching the MVC 2 project, I get a runtime error: The type 'System.Data.Objects.DataClasses.IEntityWithKey' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. However, every project references System.Data.Entity (same version). If I remove the reference to System.Data.Entity from the MVC 2 project, I get the same message as a compile-time error. I'm pretty sure something got messed up when I had the version control issue, but really not sure where to look for this one.
