  • Struts ActionError

    - by user287663
    Hi all. Anyone knows why the code below doesn't compile? The reason is that it could not find symbol for ActionError. Thanks in advance. package com.hbs; import javax.servlet.RequestDispatcher; import javax.servlet.ServletException; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpSession; import javax.servlet.http.HttpServletResponse; import org.apache.struts.action.Action; import org.apache.struts.action.ActionError; import org.apache.struts.action.ActionErrors; import org.apache.struts.action.ActionForm; import org.apache.struts.action.ActionMapping; import org.apache.struts.action.ActionForward; import org.apache.struts.util.MessageResources; import org.apache.commons.beanutils.PropertyUtils; public class FeedbackAction extends org.apache.struts.action.Action { private final static String SUCCESS = "success"; public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { ActionErrors errors = new ActionErrors(); String fullName = (String)PropertyUtils.getSimpleProperty(form, "fullName"); String fullName1 = ""; if(fullName.equals(fullName1)) { errors.add("fullName", new ActionError("error.fullName", fullName)); saveErrors(request,errors); return (new ActionForward(mapping.getInput())); } return mapping.findForward(SUCCESS); } }

  • Consuming C# Webservice

    - by Debby
    Hi, I have a simple webservice running and I have a console application client consuming the service. I did have issues getting this running and I had been helped by some wonderful people in this community. I have another problem, if i want to call the service from the client in a loop, it doesnt work. It works only for the first time and then it just keeps waiting. Why is this happening and how can I resolve it. The code: namespace WebService { [ServiceContract] public interface IService { [OperationContract(Name="Result")] [WebGet(UriTemplate = "/")] Stream Result(); } public class Service:IService { public Stream Result() { // read a file from the server and return it as stream } } } The client: namespace WebServiceClient { [ServiceContract] public interface IService { [OperationContract(Name="Result")] [WebGet(UriTemplate = "/")] Stream Result(); } } static void Main() { Console.WriteLine("Press enter when the service is available"); Console.ReadLine(); // creating factory HttpChunkingBinding binding = new HttpChunkingBinding(); binding.MaxReceivedMessageSize = 0x7fffffffL; ChannelFactory<WebServiceClient.IService> factory = new ChannelFactory<WebServiceClient.IService> (binding, new EndpointAddress("http://localhost/WebService/Service")); WebServiceClient.IService service = factory.CreateChannel(); for(int i = 0; i < 10; i++) { Stream s = service.Result(); // write this stream to a file and close the stream } //Closing our channel. ((IClientChannel)service).Close(); } Thanks,

  • Escape Quote in C# for javascript consumption

    - by Jason
    I have a ASP.Net web handler that returns results of a query in JSON format public static String dt2JSON(DataTable dt) { String s = "{\"rows\":["; if (dt.Rows.Count > 0) { foreach (DataRow dr in dt.Rows) { s += "{"; for (int i = 0; i < dr.Table.Columns.Count; i++) { s += "\"" + dr.Table.Columns[i].ToString() + "\":\"" + dr[i].ToString() + "\","; } s = s.Remove(s.Length - 1, 1); s += "},"; } s = s.Remove(s.Length - 1, 1); } s += "]}"; return s; } The problem is that sometimes the data returned has quotes in it and I would need to javascript-escape these so that it can be properly created into a js object. I need a way to find quotes in my data (quotes aren't there every time) and place a "/" character in front of them. Example response text (wrong): {"rows":[{"id":"ABC123","length":"5""}, {"id":"DEF456","length":"1.35""}, {"id":"HIJ789","length":"36.25""}]} I would need to escape the " so my response should be: {"rows":[{"id":"ABC123","length":"5\""}, {"id":"DEF456","length":"1.35\""}, {"id":"HIJ789","length":"36.25\""}]} Also, I'm pretty new to C# (coding in general really) so if something else in my code looks silly let me know.

  • Pass Variable to Java Method from an Ant Target

    - by user200317
    At the moment I have a .properties file to store settings related to the framework. Example: default.auth.url=http://someserver-at008:8080/ default.screenshots=false default.dumpHTML=false And I have written a class to extract those values and here is the method of that class. public static String getResourceAsStream(String defaultProp) { String defaultPropValue = null; //String keys = null; try { InputStream inputStream = SeleniumDefaultProperties.class.getClassLoader().getResourceAsStream(PROP_FILE); Properties properties = new Properties(); //load the input stream using properties. properties.load(inputStream); defaultPropValue = properties.getProperty(defaultProp); }catch (IOException e) { log.error("Something wrong with .properties file, check the location.", e); } return defaultPropValue; } Throughout the application I use method like follows to just exact property needed, public String getBrowserDefaultCommand() { String bcmd = SeleniumDefaultProperties.getResourceAsStream("default.browser.command"); if(bcmd.equals("")) handleMissingConfigProperties(SeleniumDefaultProperties.getResourceAsStream("default.browser.command")); return bcmd; } But I have not decided do a change to this and use ant and pass a parameter instead of using it from .properties file. I was wondering how could I pass a value to a Java Method using ANT. Non of these classes have Main methods and will not have any main. Due to this I was unable to use it as a java system properties. Thanks in advance.

  • jQuery XML loading and then innerfade effect

    - by Ryan Max
    Hello, I think I can explain myself without code, so for brevity's sake here we go: I am using jquery to pull data from an xml and put it into a ul on the page with each xml entry as a li. This is working great! However, what I am trying to do afterwards is use the innerfade plugin to make a simple animation between each of the li's. It's not working though, as it is still just loading the static list with each item visible (whereas if innerfade was working it would only display the first....then fade into the second, etc) It's not an innerfade problem however, because if I add the list in manually to the page (not injecting it with jquery) then the innerfade works fine. I'm relatively new to DOM scripting, so I think I am missing something here. I'm not quite sure how jQuery sequences everything, and I'm having trouble phrasing my question in a search engine friendly manner so here I am. Is it possible to have jquery pull the data from xml, then inject it into the page, then have innerfade work it's magic? Or am I thinking about this the wrong way? xml code: $.ajax({ type: "GET", url: "xml/playlist.xml", dataType: "xml", success: function(xml) { $(xml).find('song').each(function(){ var name = $(this).attr('title'); var date = $(this).attr('artist'); var message = $(this).attr('path'); $('<li></li>').html('<span id="an_name">'+name+'</span><span id="an_date">'+date+'</span><span id="an_message">'+message+'</span>').appendTo('#anniversary'); }); } }); innerfade code: <script type="text/javascript"> jQuery.noConflict(); jQuery(document).ready( function(){ jQuery('#anniversary').innerfade({ speed: 1000, timeout: 5000, type: 'sequence', }); });

    - by Shailesh Jaiswal
    I am developng Smart device application in C#. It is a window application. In this application I am using Login form to authenticate the users. Only authenticated users can login into the system. In this application I am calling java web services which resides on another machine. I am passing mobile number & password from mu application's login form to the java web services.

  • Memory usage in Flash / Flex / AS3

    - by ggambett
    I'm having some trouble with memory management in a flash app. Memory usage grows quite a bit, and I've tracked it down to the way I load assets. I embed several raster images in a class Embedded, like this [Embed(source="/home/gabriel/text_hard.jpg")] public static var ASSET_text_hard_DOT_jpg : Class; I then instance the assets this way var pClass : Class = Embedded[sResource] as Class; return new pClass() as Bitmap; At this point, memory usage goes up, which is perfectly normal. However, nulling all the references to the object doesn't free the memory. Based on this behavior, looks like the flash player is creating an instance of the class the first time I request it, but never ever releases it - not without references, calling System.gc(), doing the double LocalConnection trick, or calling dispose() on the BitmapData objects. Of course, this is very undesirable - memory usage would grow until everything in the SWFs is instanced, regardless of whether I stopped using some asset long ago. Is my analysis correct? Can anything be done to fix this?

  • CommandBuilder and SqlTransaction to insert/update a row

    - by Jesse
    I can get this to work, but I feel as though I'm not doing it properly. The first time this runs, it works as intended, and a new row is inserted where "thisField" contains "doesntExist" However, if I run it a subsequent time, I get a run-time error that I can't insert a duplicate key as it violate the primary key "thisField". static void Main(string[] args) { using(var sqlConn = new SqlConnection(connString) ) { sqlConn.Open(); var dt = new DataTable(); var sqlda = new SqlDataAdapter("SELECT * FROM table WHERE thisField ='doesntExist'", sqlConn); sqlda.Fill(dt); DataRow dr = dt.NewRow(); dr["thisField"] = "doesntExist"; //Primary key dt.Rows.Add(dr); //dt.AcceptChanges(); //I thought this may fix the problem. It didn't. var sqlTrans = sqlConn.BeginTransaction(); try { sqlda.SelectCommand = new SqlCommand("SELECT * FROM table WITH (HOLDLOCK, ROWLOCK) WHERE thisField = 'doesntExist'", sqlConn, sqlTrans); SqlCommandBuilder sqlCb = new SqlCommandBuilder(sqlda); sqlda.InsertCommand = sqlCb.GetInsertCommand(); sqlda.InsertCommand.Transaction = sqlTrans; sqlda.DeleteCommand = sqlCb.GetDeleteCommand(); sqlda.DeleteCommand.Transaction = sqlTrans; sqlda.UpdateCommand = sqlCb.GetUpdateCommand(); sqlda.UpdateCommand.Transaction = sqlTrans; sqlda.Update(dt); sqlTrans.Commit(); } catch (Exception) { //... } } } Even when I can get that working through trial and error of moving AcceptChanges around, or encapsulating changes within Begin/EndEdit, then I begin to experience a "Concurrency violation" in which it won't update the changes, but rather tell me it failed to update 0 of 1 affected rows. Is there something crazy obvious I'm missing?

  • How save selected switch option

    System UIviewcontroller has button , Tap on button i need to fire Info Tableviewcontroller. Tableviewcontroller itself UISwitch.

  • calling .ajax() from an eventHandler c# asp.ent

    - by ibininja
    Good day...! In the code behind (upload.aspx) I have an event that returns the number of bytes being streamed; and as I debug it, it works fine. I wanted to reflect the numbers returned from the eventHandler on a progress bar and this is where I got lost. I tried using jQuery's .ajax() function. this is how I implemented it: In the EventHandler in my code behind I added this code to call the .ajax() function: Page.ClientScript.RegisterStartupScript(this.GetType(), "UpdateProgress", "<script type='text/javascript'>updateProgress();</script>"); My plan is whenever the eventHandler function changes the values of bytes being streamed it calls the javascript function "updateProgress()" The .ajax() function "UpdateProgress()" is as: function updateProgress() { $.ajax({ type: "POST", url: "upload.aspx/GetData", data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", async: true, success: function (msg) { $("#progressbar").progressbar("option", "value", msg.d); } }); } I made sure that the function GetData() is [System.Web.Services.WebMethod] and that it is static as well. so the workflow of what I am trying to implement is as: - Click On Upload button - The Behind code starts executing and EventHandler triggers - The EventHandler calls .ajax() function - The .ajax() function retrieves the bytes being streamed and updates progress bar. When I ran the code; all runs well except that the .ajax() is only executed when upload is finished (and progress bar also updates only when finished upload); even though I call .ajax() function every time in the eventHandler function as reflected above... What am I doing wrong? Am I thinking of this right? is there anything else I should add maybe an updatePanel or something? thank you

  • How do ASP.NET MVC Routes work?

    - by Pure.Krome
    Hi folks, imagine i have the following route setup... public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", "{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = "" } ); // Added custom route here! routes.MapRoute( "CatchAll", "{*catchall}," new { controller = "Error", action = "NotFound" } ); } nothing new - that's the default ASP.NET MVC1 RegisterRoutes method, with one custom route added. Now, if I goto the following url, i get a 404... http://whatever/Home/MissingActionMethod So there's no ActionMethod called MissingActionMethod in the HomeController. So, does this mean, if i goto the 1st route defined, above .. and fail to find an action .. do I then come back and try the second route? rinse-repeat? Or once i match a route, i then try and execute that route .. and if i fail (ie, find the action is missing) .. then .. bad luck? boomski? cheers!

  • Testing In-App-Billing with not published App

    - by Janusz
    I have an Android App that uses In-App-Billing to sell Account Managed Items. I tested the App with the static respons ids and everything seems to work. I now want to test the App with real product Ids. I created the App in the Google Play Store and uploaded a draft Version of the App with the correct Permissions. I know created an In-App-Billing item and published the item. At the moment the App is unpublished, the item is created and published and I have a test account that is registered in the Profile of the developer account and is the only account on the device that I use for testing. The App is signed with the same key as the uploaded draft. Edit:I'm testing with Android 4.1 && 4.03 at the moment If I try to buy the item the Google Play Store pops up but shows a dialog with the following method: The item you requested is not available for purchase. How can I test buying the item without publishing the App?

  • Translating Where() to sql

    - by MBoros
    Hi. I saw DamienG's article (http://damieng.com/blog/2009/06/24/client-side-properties-and-any-remote-linq-provider) in how to map client properties to sql. i ran throgh this article, and i saw great potential in it. Definitely mapping client properties to SQL is an awesome idea. But i wanted to use this for something a bit more complicated then just concatenating strings. Atm we are trying to introduce multilinguality to our Business objects, and i hoped we could leave all the existing linq2sql queries intact, and just change the code of the multilingual properties, so they would actually return the given property in the CurrentUICulture. The first idea was to change these fields to XMLs, and then try the Object.Property.Elements().Where(...), but it got stuck on the Elements(), as it couldnt translate it to sql. I read somewhere that XML fields are actually regarded as strings, and only on the app server they become XElements, so this way the filtering would be on the app server anyways, not the DB. Fair point, it wont work like this. Lets try something else... SO the second idea was to create a PolyGlots table (name taken from http://weblogic.sys-con.com/node/102698?page=0,1), a PolyGlotTranslations table and a Culture table, where the PolyGlots would be referenced from each internationalized property. This way i wanted to say for example: private static readonly CompiledExpression<Announcement, string> nameExpression = DefaultTranslationOf<Announcement> .Property(e => e.Name) .Is(e=> e.NamePolyGlot.PolyGlotTranslations .Where(t=> t.Culture.Code == Thread.CurrentThread.CurrentUICulture.Name) .Single().Value ); now unfortunately here i get an error that the Where() function cannot be translated to sql, what is a bit disappointing, as i was sure it will go through. I guess it is failing, cause the IEntitySet is basically an IEnumerable, not IQueryable, am i right? Is there another way to use the compiledExpressions class to achieve this goal? Any help appreciated.

  • Best way to split a string by word (SQL Batch separator)

    - by Paul Kohler
    I have a class I use to "split" a string of SQL commands by a batch separator - e.g. "GO" - into a list of SQL commands that are run in turn etc. ... private static IEnumerable<string> SplitByBatchIndecator(string script, string batchIndicator) { string pattern = string.Concat("^\\s*", batchIndicator, "\\s*$"); RegexOptions options = RegexOptions.Compiled | RegexOptions.IgnoreCase | RegexOptions.Multiline; foreach (string batch in Regex.Split(script, pattern, options)) { yield return batch.Trim(); } } My current implementation uses a Regex with yield but I am not sure if it's the "best" way. It should be quick It should handle large strings (I have some scripts that are 10mb in size for example) The hardest part (that the above code currently does not do) is to take quoted text into account Currently the following SQL will incorrectly get split: var batch = QueryBatch.Parse(@"-- issue... insert into table (name, desc) values('foo', 'if the go is on a line by itself we have a problem...')"); Assert.That(batch.Queries.Count, Is.EqualTo(1), "This fails for now..."); I have thought about a token based parser that tracks the state of the open closed quotes but am not sure if Regex will do it. Any ideas!?

Here is my code for ASP.Net application: protected void Page_Load(object sender, EventArgs e) { string connectionString = GetConnectionString(); OracleConnection connection = new OracleConnection(connectionString); connection.Open(); Label1.Text = "State: " + connection.State; Label1.Text = "ConnectionString: " + connection.ConnectionString; OracleCommand command = connection.CreateCommand(); string sql = "SELECT * FROM Users"; command.CommandText = sql; OracleDataReader reader = command.ExecuteReader(); while (reader.Read()) { string myField = (string)reader["nID"]; Console.WriteLine(myField); } } static private string GetConnectionString() { // To avoid storing the connection string in your code, // you can retrieve it from a configuration file. return "User Id=System;Password=admin;Data Source=(DESCRIPTION=" + "(ADDRESS=(PROTOCOL=TCP)(HOST=myServerAddress)(PORT=1521))" + "(CONNECT_DATA=(SERVICE_NAME=)));"; }

  • Using libcurl to create a valid POST

    - by Haraldo
    static int get( const char * cURL, const char * cParam ) { CURL *handle; CURLcode result; std::string buffer; char errorBuffer[CURL_ERROR_SIZE]; //struct curl_slist *headers = NULL; //headers = curl_slist_append(headers, "Content-Type: Multipart/Related"); //headers = curl_slist_append(headers, "type: text/xml"); // Create our curl handle handle = curl_easy_init(); if( handle ) { curl_easy_setopt(handle, CURLOPT_ERRORBUFFER, errorBuffer); //curl_easy_setopt(handle, CURLOPT_HEADER, 0); //curl_easy_setopt(handle, CURLOPT_HTTPHEADER, headers); curl_easy_setopt(handle, CURLOPT_POST, 1); curl_easy_setopt(handle, CURLOPT_POSTFIELDS, cParam); curl_easy_setopt(handle, CURLOPT_POSTFIELDSIZE, strlen(cParam)); curl_easy_setopt(handle, CURLOPT_FOLLOWLOCATION, 1); curl_easy_setopt(handle, CURLOPT_WRITEFUNCTION, Request::writer); curl_easy_setopt(handle, CURLOPT_WRITEDATA, &buffer); curl_easy_setopt(handle, CURLOPT_USERAGENT, "libcurl-agent/1.0"); curl_easy_setopt(handle, CURLOPT_URL, cURL); result = curl_easy_perform(handle); curl_easy_cleanup(handle); } if( result == CURLE_OK ) { return atoi( buffer.c_str() ); } return 0; } Hi there, first of all I'm having trouble debugging this in visual studio express 2008 so I'm unsure what buffer.c_str() might actually be returning but I am outputting 1 or 0 to the web page being posted to. Therefore I'm expecting the buffer to be one or the other, however I seem to only be returning 0 or equivalent. Does the code above look like it will return what I expect or should my variable types be different? The conversion using "atoi" may be an issue. Any thought would be much appreciated.

  • JDO difficulties in retrieving persistent vector

    - by Michael Omer
    I know there are already some posts regarding this subject, but although I tried using them as a reference, I am still stuck. I have a persistent class as follows: @PersistenceCapable(identityType = IdentityType.APPLICATION) public class GameObject implements IMySerializable{ @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) protected Key m_databaseKey; @NotPersistent private final static int END_GAME_VAR = -1000; @Persistent(defaultFetchGroup = "true") protected GameObjectSet m_set; @Persistent protected int m_databaseType = IDatabaseAccess.TYPE_NONE; where GameObjectSet is: @PersistenceCapable(identityType = IdentityType.APPLICATION) @FetchGroup(name = "mySet", members = {@Persistent(name = "m_set")}) public class GameObjectSet { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Key id; @Persistent private Vector<GameObjectSetPair> m_set; and GameObjectSetPair is: @PersistenceCapable(identityType = IdentityType.APPLICATION) public class GameObjectSetPair { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Key id; @Persistent private String key; @Persistent(defaultFetchGroup = "true") private GameObjectVar value; When I try to fetch the entire structure by fetching the GameObject, the set doesn't have any elements (they are all null) I tried adding the fetching group to the PM, but to no avail. This is my fetching code Vector<GameObject> ret = new Vector<GameObject>(); PersistenceManager pm = PMF.get().getPersistenceManager(); pm.getFetchPlan().setMaxFetchDepth(-1); pm.getFetchPlan().addGroup("mySet"); Query myQuery = pm.newQuery(GameObject.class); myQuery.setFilter("m_databaseType == objectType"); myQuery.declareParameters("int objectType"); try { List<GameObject> res = (List<GameObject>)myQuery.execute(objectType); ret = new Vector<GameObject>(res); for (int i = 0; i < ret.size(); i++) { ret.elementAt(i).getSet(); ret.elementAt(i).getSet().touchSet(); } } catch (Exception e) { } finally { pm.close(); } Does anyone have any idea? Thanks Mike

  • Advantages/Disadvantages of different implementations for Comparing Objects using .NET

    - by Kevin Crowell
    This questions involves 2 different implementations of essentially the same code. First, using delegate to create a Comparison method that can be used as a parameter when sorting a collection of objects: class Foo { public static Comparison<Foo> BarComparison = delegate(Foo foo1, Foo foo2) { return foo1.Bar.CompareTo(foo2.Bar); }; } I use the above when I want to have a way of sorting a collection of Foo objects in a different way than my CompareTo function offers. For example: List<Foo> fooList = new List<Foo>(); fooList.Sort(BarComparison); Second, using IComparer: public class BarComparer : IComparer<Foo> { public int Compare(Foo foo1, Foo foo2) { return foo1.Bar.CompareTo(foo2.Bar); } } I use the above when I want to do a binary search for a Foo object in a collection of Foo objects. For example: BarComparer comparer = new BarComparer(); List<Foo> fooList = new List<Foo>(); Foo foo = new Foo(); int index = fooList.BinarySearch(foo, comparer); My questions are: What are the advantages and disadvantages of each of these implementations? What are some more ways to take advantage of each of these implementations? Is there a way to combine these implementations in such a way that I do not need to duplicate the code? Can I achieve both a binary search and an alternative collection sort using only 1 of these implementations?
