  • Using Crypt function Python 3.3.2

    - by adampski
    In Windows and Python version 3.3.2, I try and call the python module like so: hash2 = crypt(word, salt) I import it at the top of my program like so: from crypt import * The result I get is the following: Traceback (most recent call last): File "C:\none\of\your\business\adams.py", line 10, in <module> from crypt import * File "C:\Python33\lib\crypt.py", line 3, in <module> import _crypt ImportError: No module named '_crypt' However, when I execute the same file adams.py in Ubuntu, with Python 2.7.3, it executes perfectly - no errors. I tried the following to resolve the issue for my Windows & Python 3.3.2 (though I'm sure the OS isn't the issue, the Python version or my use of syntax is the issue): Rename the directory in the Python33 directory from Lib to lib Rename the crypt.py in lib to _crypt.py. However, it turns out the entire crypt.py module depends on an external module called _crypt.py too. Browsed internet to download anything remotely appropriate to resemble _crypt.py It's not Python, right? It's me...(?) I'm using syntaxes to import and use external modules that are acceptable in 2.7.3, but not in 3.3.2. Or have I found a bug in 3.3.2?

  • FaultException<T>() exception thrown by the service is not caught by the client catch(FaultException

    - by Ashish Gupta
    Ok, I know I am missing something here. I have the following operation contract: public double DivideByZero(int x, int y) { if (y == 0) { throw new FaultException<ArgumentException> (new ArgumentException("Just some dummy exception") ,new FaultReason("some very bogus reason"), new FaultCode("007")); } return x / y; } And following is taken from the client:- Console.WriteLine("Enter the x value"); string x = Console.ReadLine(); Console.WriteLine("Enter the Y value"); string y = Console.ReadLine(); try { double val = client.DivideByZero(Convert.ToInt32(x), Convert.ToInt32(y)); Console.WriteLine("The result is " + val.ToString()); } catch(FaultException<ArgumentException> exp) { Console.WriteLine("An ArgumentException was thrown by the service "+ exp.ToString()); } catch (Exception exp) { Console.WriteLine(exp.ToString()); } In the above case catch(FaultException exp) (the first catch block with ArgumentException in the client code) block does not get executed. However, when I remove ArgumentException to have catch(FaultException exp), the same catch block gets executed. I am not sure about this as I am throwing FaultException from my operation contract. Am I missing anything here. Appreciate your help, Ashish

  • Calling a MVC2 partial view using jquery returns empty string problem

    - by Jason
    I have an issue where I have a partial view that returns some HTML to be displayed. Its called when something is clicked on the page using jquery. The problem is that no matter how I call it, i get back an empty string even though it reports success. This is happening to me using Chrome, going against my local machine. My controller looks like this: public ActionResult MyPartialView() { return PartialView(model); } I have tried jquery using .get(), .post() and .load() and all have the same results. Here is an example using .post(): $.post(url, function (data) { alert(data); }); The result always comes back as an empty string. I can navigate to the partial view in the browser manually and i get back the desired HTML. The URL I am using to call it I resolved fully so it looks like "http://localhost/controller/mypartialview" rather than using the relative path of "/controller/mypartialview" which I thought was the original problem. Any idea what may cause this?

  • Using M2Crypto to save and load X509 certs in pem files

    - by Brock Pytlik
    I would expect that if I have a X509 cert as an object in memory, saved it as a pem file, then loaded it back in, I would end up with the same cert I started with. This seems not to be the case however. Let's call the original cert A, and the cert loaded from the pem file B. A.as_text() is identical to B.as_text(), but A.as_pem() differs from B.as_pem(). To say the least, I'm confused by this. As a side note, if A has been signed by another entity C, then A will verify against C's cert, but B will not. I've put together a tiny sample program to demonstrate what I'm seeing. When I run this, the second RuntimeError is raised. Thanks, Brock #!/usr/bin/python2.6 import M2Crypto as m2 import time cur_time = m2.ASN1.ASN1_UTCTIME() cur_time.set_time(int(time.time()) - 60*60*24) expire_time = m2.ASN1.ASN1_UTCTIME() # Expire certs in 1 hour. expire_time.set_time(int(time.time()) + 60 * 60 * 24) cs_rsa = m2.RSA.gen_key(1024, 65537, lambda: None) cs_pk = m2.EVP.PKey() cs_pk.assign_rsa(cs_rsa) cs_cert = m2.X509.X509() # These two seem the minimum necessary to make the as_text function call work # at all cs_cert.set_not_before(cur_time) cs_cert.set_not_after(expire_time) # This seems necessary to fill out the complete cert without errors. cs_cert.set_pubkey(cs_pk) # I've tried with the following set lines commented out and not commented. cs_name = m2.X509.X509_Name() cs_name.C = "US" cs_name.ST = "CA" cs_name.OU = "Fake Org CA 1" cs_name.CN = "www.fakeorg.dex" cs_name.Email = "[email protected]" cs_cert.set_subject(cs_name) cs_cert.set_issuer_name(cs_name) cs_cert.sign(cs_pk, md="sha256") orig_text = cs_cert.as_text() orig_pem = cs_cert.as_pem() print "orig_text:\n%s" % orig_text cs_cert.save_pem("/tmp/foo") tcs = m2.X509.load_cert("/tmp/foo") tcs_text = tcs.as_text() tcs_pem = tcs.as_pem() if orig_text != tcs_text: raise RuntimeError( "Texts were different.\nOrig:\n%s\nAfter load:\n%s" % (orig_text, tcs_text)) if orig_pem != tcs_pem: raise RuntimeError( "Pems were different.\nOrig:\n%s\nAfter load:\n%s" % (orig_pem, tcs_pem))

  • Instantiate an .aspx that is an embedded resource of an assembly

    - by asbjornu
    I have an ASP.NET (MVC) application in which I would like to load WebForms .aspx files that are embedded as resources in 3rd party assemblies. The reason I want to do this is to make a sort of "plug-in" system where a .dll file can be dropped in a folder and then picked up at runtime to provide additional functionality to the base application. I've gotten the plugin system to work (I'm using MEF) with plugins written in ASP.NET MVC (Views and Controllers), but for plain old ASP.NET (Pages), I've got myself into a bit of a problem. For the execution of the embedded .aspx file (which, in the usual WebForm way Inherits="My.BasePage") I've created a custom VirtualPathProvider, ResourceFile ControllerFactory and PageController. Within the PageController I've overridden the Execute(RequestContext) method and within it I'm trying to compile the .aspx with BuildManager.CreateInstanceFromVirtualPath(virtualPath, type). When doing this, I get the error message "Could not load type 'My.BasePage'", even though I'm giving the BuildManager the System.Type of My.BasePage in the call to CreateInstanceFromVirtualPath. I seem to be stuck at this point. I've tried to Server.Transfer() to the custom VirtualPathProvider handled URL to the same .aspx file, but that fails with the same error message. How can I help BuildManager find out where My.BasePage is defined and how come the Type requiredBaseType parameter of CreateInstanceFromVirtualPath seems to be ignored? I've tried to call BuildManager.AddReferencedAssembly(), but that only fails with "This method can only be called during the application's pre-start initialization stage". MSDN says: "The method must be called during the Application_PreStartInit stage of the application", but I have no such event in my HttpApplication object and find absolutely zero information about it on the internet. Either way, I don't want to be calling BuildManager.AddReferencedAssembly() in or before the Application_Start event, since that makes me have to recycle the whole application to be able to add new plugins to the system. Does anyone have any clues? Any other ideas on how I can "execute" an .aspx file that is embedded as a resource within an assembly through reflection? Can I for instance pre-compile the .aspx file within the same assembly as the base Page class it inherits?

  • OS X, Mercurial and MediaTemple problem

    - by bschaeffer
    I've installed Mercurial per MT's knowledge base file here. Working with it server side using ssh from my Mac works fine. I can initialize repositories and the like, but pulling from the server or pushing from my Mac produces an error I don't understand.

  • TreeGrid in GXT

    - by aTory
    Problem I'm trying to create an asynchronously updating TreeGrid in GXT but encountering issues. The first issue is that I believe the documentation is 'piss poor', at best.. therefore any chance of learning without using 'word of mouth' seems ridiculous. Instead of moaning any further, I shall inform you what I'd LIKE to do and then hopefully you can tell me if what i want is possible. Example knowledge of Football is recommended here I have a few Async services where: getLeagues() getTeams(League) getPlayers(League,Team) getPosition(League,Team,Player) I'd like to have a grid where once it renders, it makes a call to 'getLeagues', where by the server will respond with a bunch of leagues that are currently active on the server... these will be the 'root node' of the TreeGrid. Then, from here you can expand each league to show the teams, right down to the players and then their positions. I'd like to Create a TreeGrid which has a 'listener' on each node, waiting to asynchronously call the server on request and propogate the tree from here, however I'm not sure if this is possible. Can anybody advise? I'm finding all these Models, BaseTreeModels, TreeStores nauseating.

  • Calling Msbuild from Php - Wrong Codepage and Culture

    - by miasbeck
    I have a Php script that calls Msbuild via System: <?php system( "msbuild umlaut.proj" ); ?> This is the project file: <?xml version="1.0" encoding="UTF-8"?> <Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003" DefaultTargets="EchoUmlaut" ToolsVersion="3.5"> <Target Name="EchoUmlaut"> <Message Text="Umlaute: Ä Ö Ü ä ö ü ß" /> </Target> </Project> When I call Msbuild directly from the command line the output of msbuild is in German (as excpected) and the umlauts come out OK (I chcp to 1252).

  • Model validation with enumerable properties in Asp.net MVC2 RTM

    - by Robert Koritnik
    I'm using DataAnnotations attributes to validate my model objects. My model class looks similar to this: public class MyModel { [Required] public string Title { get; set; } [Required] public List<User> Editors { get; set; } } public class User { public int Id { get; set; } [Required] public string FullName { get; set; } [Required] [DataType(DataType.Email)] public string Email { get; set; } } My controller action looks like: public ActionResult NewItem(MyModel data) { //... } User is presented with a view that has a form with: a text box with dummy name where users enter user's names. For each user they enter, there's a client script coupled with ajax that creates an <input type="hidden" name="data.Editors[0].Id" value="userId" /> for each user entered (enumeration index is therefore not always 0 as written here), so default model binder is able to consume and bind the form without any problems. a text box where users enter the title Since I'm using Asp.net MVC 2 RTM which does model validation instead of input validation I don't know how to avoid validation errors. The thing is I have to use BindAttribute on my controller action. I would have to either provide a white or a black list of properties. It's always a better practice to provide a white list. It's also more future proof. The problem My form works fine, but I get validation errors about user's FullName and Email properties since they are not provided. I also shouldn't feed them to the client (via ajax when user enters user data), because email is personal contact data and is not shared between users. If there was just a single user reference on MyModel I would write [Bind(Include = "Title, Editor.Id")] But I have an enumeration of them. How do I provide Bind white list to work with my model?

  • Combobox with collection view itemssource does not update selection box item on changes to the Model

    - by Vinit Sankhe
    Hello, Sorry for the earlier lengthy post. Here is my concise (!) description. I bind a collection view to a combobox as a itemsSource and also bind its selectedvalue with a property from my view model. I must keep IsSynchronizedWithCurrentItem="False". I change the source list ofr the view and then refresh the view. The changed (added, removed, edited) items appear correctly in the item list of the combo. But problem is with the selected item. When I change its property which is also the displaymember path of the combo, the changed property value does not reflect back on the selecton box of the combo. If you open the combo dropdown it appears correctly on the item list but not on the selection box. Now if I change the combobox tag to Listbox in my XAML (keeping all attributes as it is) then when selected item's displaymember property value is updated, the changes reflect back on the selected item of the list box . Why this issue? Just FYI: My View Model has properties EmployeeCollectionView and SelectedEmployeeId which are bound to combo as ItemsSource and SelectedValue resp. This VM implements the INotifyPropertyChanged interface. My core employee class (list of which is the source for the EmployeeCollectionView) is simply a Model class without INotifyPropertyChanged. DisplayMemberPath is "Name" property of employee Model class. I change this by some means and expect the combo selection box to update the value. I tried refreshing ther SelectedEmployeeId by setting it 0 (where it correctly selects the dummy "-- Select All --" employee entry from itemsSource) and old selected value back. But no use. The old value takes me back to the old label. Items collection has latest entry though. When I make combobox's IsEditable=True before the view's refresh and after refresh I make IsEditable=False then the things work out correctly! But this is a patch and is unnecessary. Thx Vinit Sankhe

  • NHibernate, Databinding to DataGridView, Lazy Loading, and Session managment - need advice

    - by Tom Bushell
    My main application form (WinForms) has a DataGridView, that uses DataBinding and Fluent NHibernate to display data from a SQLite database. This form is open for the entire time the application is running. For performance reasons, I set the convention DefaultLazy.Always() for all DB access. So far, the only way I've found to make this work is to keep a Session (let's call it MainSession) open all the time for the main form, so NHibernate can lazy load new data as the user navigates with the grid. Another part of the application can run in the background, and Save to the DB. Currently, (after considerable struggle), my approach is to call MainSession.Disconnect(), create a disposable Session for each Save, and MainSession.Reconnect() after finishing the Save. Otherwise SQLite will throw "The database file is locked" exceptions. This seems to be working well so far, but past experience has made me nervous about keeping a session open for a long time (I ran into performance problems when I tried to use a single session for both Saves and Loads - the cache filled up, and bogged down everything - see http://stackoverflow.com/questions/2526675/commit-is-very-slow-in-my-nhibernate-sqlite-project). So, my question - is this a good approach, or am I looking at problems down the road? If it's a bad approach, what are the alternatives? I've considered opening and closing my main session whenever the user navigates with the grid, but it's not obvious to me how I would do that - hook every event from the grid that could possibly cause a lazy load? I have the nagging feeling that trying to manage my own sessions this way is fundamentally the wrong approach, but it's not obvious what the right one is.

  • How to use Excel VBA to extract Memo field from Access Database?

    - by the.jxc
    I have an Excel spreadsheet. I am connecting to an Access database via ODBC. Something along then lines of: Set dbEng = CreateObject("DAO.DBEngine.40") Set oWspc = dbEng.CreateWorkspace("ODBCWspc", "", "", dbUseODBC) Set oConn = oWspc.OpenConnection("Connection", , True, "ODBC;DSN=CLIENTDB;") Then I use a query and fetch a result set to get some table data. Set oQuery = oConn.CreateQueryDef("tmpQuery") oQuery.Sql = "SELECT idField, memoField FROM myTable" Set oRs = oQuery.OpenRecordset The problem now arises. My field is a dbMemo because the maximum content length is up to a few hundred chars. It's not that long, and in fact the value I'm reading is only a dozen characters. But Excel just doesn't seem able to handle the Memo field content at all. My code... ActiveCell = oRs.Fields("memoField") ...gives error Run-time error '3146': ODBC--call failed. Any suggestions? Can Excel VBA actually get at memo field data? Or is it just completely impossible. I get exactly the same error from GetChunk as well. ActiveCell = oRs.Fields("memoField").GetChunk(0, 2) ...also gives error Run-time error '3146': ODBC--call failed. Converting to a text field makes everything work fine. However some data is truncated to 255 characters of course, which means that isn't a workable solution.

  • MVC controller is being called twice

    - by rboarman
    Hello, I have a controller that is being called twice from an ActionLink call. My home page has a link, that when clicked calls the Index method on the Play controller. An id of 100 is passed into the method. I think this is what is causing the issue. More on this below. Here are some code snippets: Home page: <%= Html.ActionLink(“Click Me”, "Index", "Play", new { id = 100 }, null) %> Play Controller: public ActionResult Index(int? id) { var settings = new Dictionary<string, string>(); settings.Add("Id", id.ToString()); ViewData["InitParams"] = settings.ToInitParams(); return View(); } Play view: <%@ Page Title="" Language="C#" Inherits="System.Web.Mvc.ViewPage" %> (html <head> omitted for brevity) <body> <form id="form1" runat="server" style="height:100%"> Hello </form> </body> If I get rid of the parameter to the Index method, everything is fine. If I leave the parameter in place, then the Index method is called with 100 as the id. After returning the View, the method is called a second time with a parameter of null. I can’t seem to figure out what is triggering the second call. My first thought was to add a specific route like this: routes.MapRoute( "Play", // Route name "Play/{id}", // URL with parameters new {controller = "Play", action = "Index"} // Parameter defaults ); This had no effect other than making a prettier looking link. I am not sure where to go from here. Thank you in advance. Rick

  • .NET Remoting Exception not handled Client-Side

    - by DanJo519
    I checked the rest of the remoting questions, and this specific case did not seem to be addressed. I have a .NET Remoting server/client set up. On the server side I have an object with a method that can throw an exception, and a client which will try to call that method. Server: public bool MyEquals(Guid myGuid, string a, string b) { if (CheckAuthentication(myGuid)) { logger.Debug("Request for \"" + a + "\".Equals(\"" + b + "\")"); return a.Equals(b); } else { throw new AuthenticationException(UserRegistryService.USER_NOT_REGISTERED_EXCEPTION_TEXT); } } Client: try { bool result = RemotedObject.MyEquals(myGuid, "cat", "dog"); } catch (Services.Exceptions.AuthenticationException e) { Console.WriteLine("You do not have permission to execute that action"); } When I call MyEquals with a Guid which causes CheckAuthentication to return false, .NET tries to throw the exception and says the AuthenticationException was unhandled. This happens server side. The exception is never marshaled over to the client-side, and I cannot figure out why. All of the questions I have looked at address the issue of an exception being handled client-side, but it isn't the custom exception but a base type. In my case, I can't even get any exception to cross the remoting boundary to the client. Here is a copy of AuthenticationException. It is in the shared library between both server and client. [Serializable] public class AuthenticationException : ApplicationException, ISerializable { public AuthenticationException(string message) : base(message) { } public AuthenticationException(SerializationInfo info, StreamingContext context) : base(info, context) { } #region ISerializable Members void ISerializable.GetObjectData(SerializationInfo info, StreamingContext context) { base.GetObjectData(info, context); } #endregion }

  • MVVM - ListBox SelectedItem Binding Property Going Null

    - by Peanut
    So i have a listbox: <ListBox x:Name="listbox" HorizontalAlignment="Left" Margin="8,8,0,8" Width="272" BorderBrush="{x:Null}" Background="{x:Null}" Foreground="{x:Null}" ItemsSource="{Binding MenuItems}" ItemTemplate="{DynamicResource MenuItemsTemplate}" SelectionChanged="ListBox_SelectionChanged" SelectedItem="{Binding SelectedItem}"> </ListBox> and i have this included in my viewmodel: public ObservableCollection<MenuItem> MenuItems { get { return menuitems; } set { menuitems = value; NotifyPropertyChanged("MenuItems"); } } public MenuItem SelectedItem { get { return selecteditem; } set { selecteditem = value; NotifyPropertyChanged("SelectedItem"); } } and also in my viewmodel: public void UpdateStyle() { ActiveHighlight = SelectedItem.HighlightColor; ActiveShadow = SelectedItem.ShadowColor; } So, the objective is to call UpdateStyle() whenever selectedchanged event is fired. So in the .CS file, i call UpdateStyle(). The problem is, whenever I get into the selectionchanged event method, my ViewModel.SelectedItem is always null. I tried debugging this to see if the binding was working correctly, and it is. When I click on an item in the listbox, the SelectedItem Set is triggered, setting the value... but somewhere inbetween that and the selected changed (In the CS File) It gets reset to Null. Can anyone help out? Thanks

  • rand() generating the same number – even with srand(time(NULL)) in my main!

    - by Nick Sweet
    So, I'm trying to create a random vector (think geometry, not an expandable array), and every time I call my random vector function I get the same x value, thought y and z are different. int main () { srand ( (unsigned)time(NULL)); Vector<double> a; a.randvec(); cout << a << endl; return 0; } using the function //random Vector template <class T> void Vector<T>::randvec() { const int min=-10, max=10; int randx, randy, randz; const int bucket_size = RAND_MAX/(max-min); do randx = (rand()/bucket_size)+min; while (randx <= min && randx >= max); x = randx; do randy = (rand()/bucket_size)+min; while (randy <= min && randy >= max); y = randy; do randz = (rand()/bucket_size)+min; while (randz <= min && randz >= max); z = randz; } For some reason, randx will consistently return 8, whereas the other numbers seem to be following the (pseudo) randomness perfectly. However, if I put the call to define, say, randy before randx, randy will always return 8. Why is my first random number always 8? Am I seeding incorrectly?

  • Problem with Informix JDBC, MONEY and decimal separator in string literals

    - by Michal Niklas
    I have problem with JDBC application that uses MONEY data type. When I insert into MONEY column: insert into _money_test (amt) values ('123.45') I got exception: Character to numeric conversion error The same SQL works from native Windows application using ODBC driver. I live in Poland and have Polish locale and in my country comma separates decimal part of number, so I tried: insert into _money_test (amt) values ('123,45') And it worked. I checked that in PreparedStatement I must use dot separator: 123.45. And of course I can use: insert into _money_test (amt) values (123.45) But some code is "general", it imports data from csv file and it was safe to put number into string literal. How to force JDBC to use DBMONEY (or simply dot) in literals? My workstation is WinXP. I have ODBC and JDBC Informix client in version 3.50 TC5/JC5. I have set DBMONEY to just dot: DBMONEY=. EDIT: Test code in Jython: import sys import traceback from java.sql import DriverManager from java.lang import Class Class.forName("com.informix.jdbc.IfxDriver") QUERY = "insert into _money_test (amt) values ('123.45')" def test_money(driver, db_url, usr, passwd): try: print("\n\n%s\n--------------" % (driver)) db = DriverManager.getConnection(db_url, usr, passwd) c = db.createStatement() c.execute("delete from _money_test") c.execute(QUERY) rs = c.executeQuery("select amt from _money_test") while (rs.next()): print('[%s]' % (rs.getString(1))) rs.close() c.close() db.close() except: print("there were errors!") s = traceback.format_exc() sys.stderr.write("%s\n" % (s)) print(QUERY) test_money("com.informix.jdbc.IfxDriver", 'jdbc:informix-sqli://169.0.1.225:9088/test:informixserver=ol_225;DB_LOCALE=pl_PL.CP1250;CLIENT_LOCALE=pl_PL.CP1250;charSet=CP1250', 'informix', 'passwd') test_money("sun.jdbc.odbc.JdbcOdbcDriver", 'jdbc:odbc:test', 'informix', 'passwd') Results when I run money literal with dot and comma: C:\db_examples>jython ifx_jdbc_money.py insert into _money_test (amt) values ('123,45') com.informix.jdbc.IfxDriver -------------- [123.45] sun.jdbc.odbc.JdbcOdbcDriver -------------- there were errors!

  • IEnumerable<T> and reflection

    - by Aren B
    Background Working in .NET 2.0 Here, reflecting lists in general. I was originally using t.IsAssignableFrom(typeof(IEnumerable)) to detect if a Property I was traversing supported the IEnumerable Interface. (And thus I could cast the object to it safely) However this code was not evaluating to True when the object is a BindingList<T>. Next I tried to use t.IsSubclassOf(typeof(IEnumerable)) and didn't have any luck either. Code /// <summary> /// Reflects an enumerable (not a list, bad name should be fixed later maybe?) /// </summary> /// <param name="o">The Object the property resides on.</param> /// <param name="p">The Property We're reflecting on</param> /// <param name="rla">The Attribute tagged to this property</param> public void ReflectList(object o, PropertyInfo p, ReflectedListAttribute rla) { Type t = p.PropertyType; //if (t.IsAssignableFrom(typeof(IEnumerable))) if (t.IsSubclassOf(typeof(IEnumerable))) { IEnumerable e = p.GetValue(o, null) as IEnumerable; int count = 0; if (e != null) { foreach (object lo in e) { if (count >= rla.MaxRows) break; ReflectObject(lo, count); count++; } } } } The Intent I want to basically tag lists i want to reflect through with the ReflectedListAttribute and call this function on the properties that has it. (Already Working) Once inside this function, given the object the property resides on, and the PropertyInfo related, get the value of the property, cast it to an IEnumerable (assuming it's possible) and then iterate through each child and call ReflectObject(...) on the child with the count variable.

  • Really slow obtaining font metrics.

    - by Artur
    So the problem I have is that I start my application by displaying a simple menu. To size and align the text correctly I need to obtain font metrics and I cannot find a way to do it quickly. I tested my program and it looks like whatever method I use to obtain font metrics the first call takes over 500 milliseconds!? Because of it the time it takes to start-up my application is much longer than necessary. I don't know if it is platform specific or not, but just in case, I'm using Mac OS 10.6.2 on MacBook Pro (hardware isn't an issue here). If you know a way of obtaining font metrics quicker please help. I tried these 3 methods for obtaining the font metrics and the first call is always very slow, no matter which method I choose. import java.awt.Font; import java.awt.FontMetrics; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.font.FontRenderContext; import java.awt.font.LineMetrics; import javax.swing.JFrame; public class FontMetricsTest extends JFrame { public FontMetricsTest() { setVisible(true); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } @Override public void paint(Graphics g) { Graphics2D g2 = (Graphics2D) g; Font font = new Font("Dialog", Font.BOLD, 10); long start = System.currentTimeMillis(); FontMetrics fontMetrics = g2.getFontMetrics(font); // LineMetrics fontMetrics1 = // font.getLineMetrics("X", new FontRenderContext(null, false, false)); // FontMetrics fontMetrics2 = g.getFontMetrics(); long end = System.currentTimeMillis(); System.out.println(end - start); g2.setFont(font); } public static void main(String[] args) { new FontMetricsTest(); } }

  • Jaxb2Marshaller and primitive types

    - by Thomas Einwaller
    Is it possible to create a web service operation using primitive or basic Java types when using the Jaxb2Marschaller in spring-ws? For example a method looking like this: @Override @PayloadRoot(localPart = "AddTaskRequest", namespace = "http://example.com/examplews/") public long addTask(final Task task) throws AddTaskFault { // do something return 0; } I am using the maven jaxws plugin to generate the interface and model classes from my WSDL. When I try to call the webservice I get the following error: java.lang.IllegalStateException: No adapter for endpoint [...]: Does your endpoint implement a supported interface like MessageHandler or PayloadEndpoint I found out that if I change the method to that: @Override @PayloadRoot(localPart = "AddTaskRequest", namespace = "http://example.com/examplews/") public JAXBElement<Long> addTask(final JAXBElement<Task> task) throws AddTaskFault { final ObjectFactory objectFactory = new ObjectFactory(); return objectFactory.createAddTaskResponse(0L); } I am able to call it - but this signature is not compatible with the interface generated by the maven jaxws plugin. What can I do to configure either spring-ws to be able to use the first kind of implementation or to tell maven jaxws plugin to generate the second variant of the interface? UPDATE: My relevant spring-ws config entries look like that: <bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller"> <property name="contextPath" value="com.example.examplews" /> </bean> <bean class="org.springframework.ws.server.endpoint.adapter.GenericMarshallingMethodEndpointAdapter"> <constructor-arg ref="marshaller" /> </bean> <bean class="org.springframework.ws.server.endpoint.mapping.PayloadRootAnnotationMethodEndpointMapping"> <property name="order" value="1" /> </bean>

  • Table element in CSS table-cell offsets other table-cell contents

    - by Matt Joiner
    The following table element in the "center" div causes the contents in the "left" divs to be offset by several pixels from the top (8 in my browser). Adding some text prior to the table removes this offset. Why? How do I stop this from happening without requiring a "dummy" line of text before my table? <html> <head> <style type="text/css"> #left { display: table-cell; background-color: blue; } #menu { background-color: green; } #center { background-color: red; display: table-cell; } </style> <body> <div id="left"> <div id="menu"> Menu 1<br> Menu 2<br> </div> </div> <div id="center"> <table><tr><td>This is the main contents.</tr></td></table> </div> <div id="left"> <div id="menu"> Menu 1<br> Menu 2<br> </div> </div> </body> </html>

  • "Parameter type conflict" when calling Java Stored Procedure within another Java Stored Procedure

    - by GuiPereira
    Here's the problem (sorry for the bad english): i'm working with JDeveloper and Oracle10g, and i have a Java Stored Procedure that is calling another JSP like the code: int sd = 0; try { CallableStatement clstAddRel = conn.prepareCall(" {call FC_RJS_INCLUIR_RELACAO_PRODCAT(?,?)} "); clstAddRel.registerOutParameter(1, Types.INTEGER); clstAddRel.setString(1, Integer.toString(id_produto_interno)); clstAddRel.setString(2, ac[i].toString()); clstAddRel.execute(); sd = clstAddRel.getInt(1); } catch(SQLException e) { String sqlTeste3 = "insert into ateste values (SQ_ATESTE.nextval, ?)"; PreparedStatement pstTeste3 = conn.prepareStatement(sqlTeste3); pstTeste3.setString(1,"erro: "+e.getMessage()+ ac[i]); pstTeste3.execute(); pstTeste3.close(); } I'm recording the error in a table called ATESTE because this JavaSP is a procedure and not a function, I've to manipulate DML inside. So, the error message I'm getting is: 'parameter type conflict'... the function "FC_RJS_INCLUIR_RELACAO_PRODCAT" it's a Java Stored Procedure too, it's already exported to Oracle, and returns an int variable, and i have to read this to decide which webservice i will call from this JavaSP. I have already tried the OracleTyep.NUMBER in the registerOutParameter. Anyone knows what i'm doing wrong?
