  • Up to date, JPA compliant GenericDAO Implementation

    - by HDave
    I read this article: http://www.ibm.com/developerworks/java/library/j-genericdao.html several times and believe I understand what it is saying. However, it is 4 years old and I have a JPA compliant Java application to contend with. In addition, I see that there is a JPATemplate in Spring that has some good functionality, but the Spring documentation says it is already deprecated! Can anybody point me to a solid, modern, JPA compliant, Spring based, working example of a GenericDAOImpl that proxies an Interface to provide generic finder execution?

  • how to get the sql connection

    - by sweetsecret
    FS_Setting is a VB class which has all the details of the connections ie: Public Class FS_Setting Public Function Get_RS_Connection() As SqlConnection Try Get_RS_Connection = New SqlConnection("Data Source=***********;User ID=sa;Password=*****;database=*********") Catch ex As System.Exception Throw New System.Exception("Get_RS_Connection Error:" + ex.Message) End Try End Function I need to call the function Get_RS_Connection() in a different class instead of getting the connection all the way again and hard coding.... I want to call the above class where the SQL connection is declared Namespace FS_Library Public Class FS_Errorlog Inherits FS_BaseClass Try **cn = New SqlConnection("Data Source=***********;UserID=sa;Password=*****;database=*********")** cmd = New SqlCommand("dbo.FS_ErrorLog_ADD", cn) cmd.CommandType = CommandType.StoredProcedure cmd.CommandTimeout = Convert.ToInt32(ConfigurationSettings.AppSettings("Command_Timeout")) Me.AddParameter(cmd, "@p_tableKey", SqlDbType.Int, tableKey) Me.AddParameter(cmd, "@p_FunctionCode", SqlDbType.Int, FunctionCode) Me.AddParameter(cmd, "@p_TableAlias", SqlDbType.VarChar, TableAlias) Me.AddParameter(cmd, "@p_ValidationCode", SqlDbType.Int, ValidationCode) If Filename = "" Then Filename = "N/A" End If Me.AddParameter(cmd, "@p_FileName", SqlDbType.VarChar, Filename) Me.AddParameter(cmd, "@p_Message", SqlDbType.VarChar, Message) Me.AddParameter(cmd, "@p_CreateUser", SqlDbType.VarChar, userID) Me.AddParameter(cmd, "@p_UserActionID", SqlDbType.UniqueIdentifier, UserActionID) cn.Open()

  • How to call a Thor task multiple times?

    - by deepak
    Thor like Rake (and Make) has task management. If I call a task multiple times, it will effectively call the task only once. How can I call a task multiple times? I tried modifying the @_invocations hash, but that did not work: require 'csv' require './config/environment' class MisReport < Thor desc "all", "generate mysql and postgres mis" def all generate("pg_mis_report", "pg") generate("mysql_mis_report", "mysql") end desc "generate", "generate mis report" def generate(file_name = "mis_report_#{Time.now.to_s(:number)}", connection = "postgres") if connection == "pg" puts "== postgres database" ActiveRecord::Base.establish_connection :development_mysql else puts "== mysql database" ActiveRecord::Base.establish_connection :development end # generate MIS puts puts "mis file is at: #{file_path}" end end

  • Searching for Records

    - by 47
    I've come up with a simple search view to search for records in my app. The user just enters all parameters in the search box then all this is matched against the database, then results are returned. One of these fields is the phone number....now in the database it's stored in the format XXX-XXX-XXX. A search, for example, for "765-4321" pull up only "416-765-4321...however I want it to return both "416-765-4321" and "4167654321" My view is as below: def search(request, page_by=None): query = request.GET.get('q', '') if query: term_list = query.split(' ') q = Q(first_name__icontains=term_list[0]) | Q(last_name__icontains=term_list[0]) | Q(email_address__icontains=term_list[0]) | Q(phone_number__icontains=term_list[0]) for term in term_list[1:]: q.add((Q(first_name__icontains=term) | Q(last_name__icontains=term) | Q(email_address__icontains=term) | Q(phone_number__icontains=term)), q.connector) results = Customer.objects.filter(q).distinct() all = results.count() else: results = [] if 'page_by' in request.GET: page_by = int(request.REQUEST['page_by']) else: page_by = 50 return render_to_response('customers/customers-all.html', locals(), context_instance=RequestContext(request))

  • Posting from JQuery to WCF Service

    - by Villager
    Hello, I have a WCF Service (called "myservice.svc") that takes a message from a user and saves it to the database. It returns a response to the user in the form of a number. This operation looks like this: [OperationContract] [WebGet] public string SubmitMessage(string message) { try { // SAVE TO DATABASE return "1"; } catch (Exception ex) { return "0"; } } I want to call this operation from some JQuery. I'm using the approach shown here: $.getJSON( "/services/myService.svc", {message:"some text"}, function (data) { alert("success"); } ); Oddly, the "success" alert is never displayed. In addition, I have set a breakpoint in my WCF service and it is never being tripped. What am I doing wrong? Thank you

  • Reading correctly alphanumeric fields into R

    - by gd047
    A tab-delimited text file, which is actually an export (using bcp) of a database table, is of that form: 102 1 01 e113c 3224.96 12 102 1 01 e185 101127.25 12 102 2 01 e185 176417.90 12 102A 3 01 e185 26261.03 12 I tried to import it in R with a command like data <- read.delim("C:\\test.txt", header = FALSE, sep = "\t") The problem is that the 3rd column which is actually a varchar field (alphanumeric) is mistakenly read as integer (as there are no letters in the entire column) and the leading zeros disappeared. The same thing happened when I imported the data directly from the database, using odbcConnect. Again that column was read as integer. str(data) $ code: int 1 1 1 1 1 1 6 1 1 8 ... How can I import such a dataset in R correctly, so as to be able to safely populate that db table again, after doing some data manipulations?

  • How to create a CMS web site using OFBiz

    I need a simple how-to tutorial on developing a simple CMS web site using the OFBiz CMS framework. There are absolutely no documentation of how OFBiz CMS works.

If somebody can illustrate just a "Hello World" like application in OFBiz CMS, it will great help for me. Or can guide me to similar documents in web.

  • Applying Domain Model on top of Linq2Sql entities

    - by Thomas
    I am trying to practice the model first approach and I am putting together a domain model. My requirement is pretty simple: UserSession can have multiple ShoppingCartItems. I should start off by saying that I am going to apply the domain model interfaces to Linq2Sql generated entities (using partial classes). My requirement translates into three database tables (UserSession, Product, ShoppingCartItem where ProductId and UserSessionId are foreign keys in the ShoppingCartItem table). Linq2Sql generates these entities for me. I know I shouldn't even be dealing with the database at this point but I think it is important to mention. The aggregate root is UserSession as a ShoppingCartItem can not exist without a UserSession but I am unclear on the rest. What about Product? It is defiently an entity but should it be associated to ShoppingCartItem? Here are a few suggestion (they might all be incorrect implementations): public interface IUserSession { public Guid Id { get; set; } public IList<IShoppingCartItem> ShoppingCartItems{ get; set; } } public interface IShoppingCartItem { public Guid UserSessionId { get; set; } public int ProductId { get; set; } } Another one would be: public interface IUserSession { public Guid Id { get; set; } public IList<IShoppingCartItem> ShoppingCartItems{ get; set; } } public interface IShoppingCartItem { public Guid UserSessionId { get; set; } public IProduct Product { get; set; } } A third one is: public interface IUserSession { public Guid Id { get; set; } public IList<IShoppingCartItemColletion> ShoppingCartItems{ get; set; } } public interface IShoppingCartItemColletion { public IUserSession UserSession { get; set; } public IProduct Product { get; set; } } public interface IProduct { public int ProductId { get; set; } } I have a feeling my mind is too tightly coupled with database models and tables which is making this hard to grasp. Anyone care to decouple?

  • Manually inserting varbinary data into SQL Server

    - by Jeremy Jarrell
    Hi, We have a SQL Server table for user settings. Originally the settings were domain objects which had been serialized as XML into the table but we recently begun serializing them as binary. However, as part of our deployment process we statically pre-populate the table with predefined settings for our users. Originally, this was as simple as copying the XML from a customized database and pasting it into an INSERT statement that was ran after the database was built. However, since we've moved to storing the settings as binary data we can't get this to work. How can we extract binary data from a varbinary column in SQL Server and paste it into a static INSERT script? We only want to use SQL for this, we don't want to use any utilities. Thanks in advance, Jeremy

    - by c11ada
    hey all, im using linq2SQL to grab information from my SQL database, i have a gridview which shows all the top level information, in this case a list of groups (i.e admin, users and so on) when a user clicks say the admin group, i want to be able to show each member in that group, i have the following code which grabs the information from the database, DataClassesDataContext dc = new DataClassesDataContext(); GridViewRow row = GridView1.SelectedRow; var query1 = from p in dc.Users where p.groups.GroupID == Int32.Parse(row.Cells[1].Text) select new { p.Name, p.Address, p.Contact Number, p.Bio, }; i no i can use gridview again to display the results of the query, but this doesnt really look nice as it shows too much information at one, how would i go about having some sort of display which will show just one user at a time giving me the chance to click next and back ? thanks

  • how to find selected elements with Jquery UI selectable

    - by kevzettler
    Hi All, I am looking for info on the event and ui objects the jquery selectable events: "selecting", and "start" take as parameters. I cannot find this in the documentation and looping through the properties is no help. $('#content_td_account').selectable({ filter: 'li:not(".non_draggable")', selecting: function(event, ui) { } }); Specifically I want to find what elements are being selected and check them to see if their parent elements are the same or not. I assumed this would be in the ui object some where.

  • How do i enable transactions

    - by acidzombie24
    I have a similar question of how to check if you are in a transaction. Instead of checking how do i allow nested transactions? I am using Microsoft SQL File Database with ADO.NET. I seen examples using tsql and examples starting transactions using begin and using transaction names. When calling connection.BeginTransaction i call another function pass in the same connection and it calls BeginTransaction again which gives me the exception SqlConnection does not support parallel transactions. It appears many microsoft variants allow this but i cant figure out how to do it with my .mdf file. How do i allow nested transactions with a Microsoft SQL File Database using C# and ADO.NET?
