  • getResourceAsStream not loading resource

    - by Michal Gorecki
    The project that I am currently working on utilizes an old application contained within a .jar file. One of the responsibilities of this application is that it updates the database when changes to the configuration files are made. Every time I try to run this file (which is a simple Ant Task extension), I get an exception thrown early in the process. I decompiled the Java file responsible, and found that the exception being thrown happens here. I do not know what the issue is, as "hibernate.cfg.xml" is contained within the same .jar file as the .class throwing the exception. ClassLoader loader = Thread.currentThread().getContextClassLoader(); InputStream in = loader.getResourceAsStream("hibernate.cfg.xml"); if (in == null) { throw new RuntimeException("Couldn't find built in hibernate config"); } If anyone has any ideas, even pointing me in the right direction, I would be grateful. Of course, any solution will have to be external, as the client already has this build of the program in production use.

  • C# property in a form class only accessable after formload event

    - by Spooky2010
    using vs2008, c# Howdy, Im instantiating and calling Form B from Form A. FormB has some custom properties, to allow me to pass it things like sqlAdaptors and dataset instances. When i instantiate and show Form B from Form A as a dialog form with a Using statement, it all works fine, but i find the properties i pass are not available in Form B until after the form_load event has fired. I was under the impression the properties when passed to a instantiated class should be available from a constructor, but this is not the case. If it try to access the properties before the form load event i get a null reference exception. Is this correct behavior ? It is very annoying. thanks for any help

  • How to find date ranges in records with consecutive dates and duplicate data

    - by alan s
    There's probably any easy solution for this, but I can't see it. I have a table with consecutive dates and often duplicate associated data for several of these consecutive dates: Date Col1 Col2 5/13/2010 1 A 5/14/2010 1 A 5/15/2010 2 B 5/16/2010 1 A 5/17/2010 1 A 5/18/2010 3 C 5/19/2010 3 C 5/20/2010 3 C Using MS T-SQL, I wish to find the start and end dates for each run of distinct Col1 and Col2 values: StartDate EndDate Col1 Col2 5/13/2010 5/14/2010 1 A 5/15/2010 5/15/2010 2 B 5/16/2010 5/17/2010 1 A 5/18/2010 5/20/2010 3 C Assumptions: There are never any missing dates. Col1 and Col2 are not null. Any ideas - preferably that don't use cursors? Many thanks, -alan

  • How to get InnerText of IFrame from another site?

    - by Eclipsed4utoo
    I am trying to do some screen-scraping of a website. The content that I want to get is inside of an IFrame. How do I get the InnerText or HTML that is being displayed inside of the IFrame? I am using .Net 4.0 and C#. I want to be able to do this from a WinForm. I tried this, but can't find where to get the actual data from... void PageCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { WebBrowser b = sender as WebBrowser; string response = b.DocumentText; HtmlElement element = b.Document.GetElementById("profileFrame"); if (element != null) { // do something with the data } } I've tried searching through the element but couldn't find any of the HTML. Is this possible?

  • Relogging a user in with different Spring Security Authorities programmatically

    - by user1331982
    PreReq: User logs in and is given roles got from the database using a custom implementation of userService. i.e. authentication-provider user-service-ref="securityPolicyService" The implemented method loadUserByUsername gets called and the roles are load for the user for the particular club they are logging into, Default one is loaded first time in. The user then click on a different club from the UI and I call a method on a service that gets the new list of authorities for this club. I then perform the following: Object principle = SecurityContextHolder.getContext().getAuthentication().getPrincipal(); SecureMember sm = (SecureMember) principle; Authentication auth = new UsernamePasswordAuthenticationToken(sm, null, newAuthories); <br><br> SecurityContextHolder.getContext().setAuthentication(auth);<br> request.getSession(false).invalidate(); SecureMember extends User from SpringFramework. The problem is the SecureMember authorities are never updated with the new ones. thanks Gary

  • Template Parameter Initialization

    - by isurulucky
    Hi, I wrote some C++ code in which I used Templates. Since I used templates, I could not initialize a couple of template class variables. I got an warning message from valgrind saying Conditional jump or move depends on uninitialized value(s). So is there a way to get around this and/or initialize template variables?? I couldn't think of a way to do it because even if I initailize them as NULL, when I use string data type a run time failure occurres. Thank You!

  • How to remove characters from a string?

    - by masato-san
    Hi, Below is interview question so you cannot relay on the functions that predefined in libraries. Also my answer below set the element to null but there is another ways to solve the problem. Given string $string = "This is a pen", remove "is" so that return value is "Th a pen" (including whitespece). I've tried (shown below) but returned value is not correct. Thanks in advance! function remove_delimiter_from_string(&$string, $del) { for($i=0; $i<strlen($string); $i++) { for($j=0; $j<strlen($del); $j++) { if($string[$i] == $del[$j]) { $string[$i] = $string[$i+$j]; //this grabs delimiter :( } } } echo $string . "\n"; }

  • Dynamically Loading a DLL

    - by TooFat
    I am trying to simply load a dll written in C# at run time and create an instance of a class in that dll. Assembly a = Assembly.LoadFrom(@"C:\Development\DaDll.dll"); Type type = a.GetType("FileReleaseHandler", true); TestInterface.INeeedHelp handler = Activator.CreateInstance(type) as TestInterface.INeeedHelp; No errors are thrown, and if I step through the code I can walk though the FileReleaseHandler Class as it executes the constructor but the value of handler is always null. What am I missing here? or even is there a better way I should be going about this?

  • How to specify schema location in an xsd file?

    - by Manoj
    I have an xsd file Foo.xsd. I tried following ways to refer it in a WSDL file but it doesnt work. 1) placed the xsd file in local file system and imported it as <xsd:import namespace="http://ws.test.com/" schemaLocation="file:///D:/wsdl/Foo.xsd"></xsd:import> 2) Placed the xsd file in web root folder and imported as <xsd:import namespace="http://ws.test.com/" schemaLocation="http://localhost:8080/Xfire/Foo.xsd"></xsd:import> When I run the client I get null for the fields of response object. But this works when I embed the type definition inside the WSDL itself. How do we specify the path to external xsds? I am using xFire 1.2.6 for generating webservices. Client is generated using xFire WSGen ant task.

  • On-the-fly thumbnails PHP

    - by Wayne
    I came up with this: <?php $dir = $_GET['dir']; header('Content-type: image/jpeg'); $create = imagecreatetruecolor(150, 150); $img = imagecreatefromjpeg($dir); imagecopyresampled($create, $img, 0, 0, 0, 0, 150, 150, 150, 150); imagejpeg($create, null, 100); ?> It works by accessing: http://domain.com/image.php?dir=thisistheimage.jpg Which works fine... but the output is awful: Can someone fix my code for the image to be 150 x 150 covering the black area... Thanks.

  • When calling CRUD check if "parent" exists with read or join?

    - by Trick
    All my entities can not be deleted - only deactivated, so they don't appear in any read methods (SELECT ... WHERE active=TRUE). Now I have some 1:M tables on this entities on which all CRUD operations can be executed. What is more efficient or has better performance? My first solution: To add to all CRUD operations: UPDATE ... JOIN entity e ... WHERE e.active=TRUE My second solution: Before all CRUD operations check if entity is active: if (getEntity(someId) != null) { //do some CRUD } In getEntity there's just SELECT * FROM entity WHERE id=? AND active=TRUE. Or any other solution, recommendation,...?

  • problem adding a where clause to a T-sql LEFT OUTER JOIN query

    - by Nickson
    SELECT TOP (100) PERCENT dbo.EmployeeInfo.id, MIN(dbo.EmployeeInfo.EmpNo) AS EmpNo, SUM(dbo.LeaveApplications.DaysAuthorised) AS DaysTaken FROM dbo.EmployeeInfo LEFT OUTER JOIN dbo.LeaveApplications ON dbo.EmployeeInfo.id = dbo.LeaveApplications.EmployeeID WHERE (YEAR(dbo.LeaveApplications.ApplicationDate) = YEAR(GETDATE())) GROUP BY dbo.EmployeeInfo.id, dbo.EmployeeMaster.EmpNo ORDER BY DaysTaken DESC The basic functionality i want is to retrieve all records in table dbo.EmployeeInfo irrespective of whether a corresponding record exists in table dbo.LeaveApplications. If a row in EmployeeInfo has no related row in LeaveApplications, i want to return its SUM(dbo.LeaveApplications.DaysAuthorised) AS DaysTaken column as NULL or may be even put a 0. With the above query, if i remove the where condition, am able to achieve what i want, but problem is i also want to return related rows from LeaveApplication only if ApplicationDate is in the current year. Now with the where condition added, am only able to get rows from EmployeeInfo only if they have corresponding rows in LeaveApplications yet i just wanted rows all in EmployeeInfo

  • how to store passwords in database?

    - by rgksugan
    I use jsp and servlets in my web application. i need to store passwords in the database. I found that hashing will be the best way to do that. I used this code to do it. java.security.MessageDigest d = null; d = java.security.MessageDigest.getInstance("SHA-1"); d.reset(); d.update(pass.getBytes("UTF-8")); byte b[] = d.digest(); String tmp = (new BASE64Encoder()).encode(b); When i tried to print the value of tmp, i get some other value.i guess its the hash value of the password. But when i persist this data to the database the original password gets saved there other than the value in tmp.. What is the problem???

  • scanf formatting issue

    - by da_rockwilder
    I have a log file with the following format: INFO 2011-03-09 10:26:15,270 [user] message I want to parse the log file using PHP: // assume file exists and all that $handle = fopen("log_file.txt", "r"); while ($line_data = fscanf($handle, "%s %s %s [%s] %s\n")) { var_dump($line_data); } fclose($handle); When I run this code I get: [0]=> array(5) { [0]=> string(4) "INFO" [1]=> string(10) "2011-03-09" [2]=> string(12) "10:26:15,270" [3]=> string(5) "user]" [4]=> NULL } // snip It appears the closing bracket in the format string ("%s %s %s [%s] %s") is disrupting the rest of the line from getting parsed. I checked the PHP docs for scanf (as suggested by fscanf), and I didn't see anything mentioning having to escape a left bracket. Any suggestions on how to get the 4th and 5th elements to look like "user" and "message" respectively?

  • C# / Entity Framework / Linq question regarding calling a method when a class is accessed...

    - by Daniel
    So this is probably really basic, but I'm fairly new to all this. I am using Entity Framework with POCO entities. I want to call a method when a class property is set. I am trying to build an advertisement platform. I have a Customer class, a Venue class and an Advertisement class. I have my indexes set up in such a way that I can call customer.venue. However, I want to be able to call Customer.Venue.CurrentAdvertisement and have it execute a method (if CurrentAdvertisement is null) and return the current advertisement. I know I can explicitly set it every time, but I want to be able to override my classes so that whenever the CurrentAdvertisement property is accessed via LINQ it runs that method to return an ad. In order to do this I need to pass the Venue class a variable (venue name).

  • @Resource annotated member not injected - bad code or bug?

    - by Brabster
    I am using an @Resource annotation in a class instantiated in a ServletContextListener's contextInitialized(...) method, but the member is always null. Here's my sample code. Listener: public void contextInitialized(ServletContextEvent sce) { System.err.println("In contextInitialised"); new ResourceListenerTargetTest().executeMe(); } ResourceListenerTargetTest: @Resource(name="MyJDBCResource") private DataSource source; public void executeMe() { /*try { InitialContext ictx = new InitialContext(); source = (DataSource)ictx.lookup("java:comp/env/MyJDBCResource"); } catch (NamingException e) { e.printStackTrace(); }*/ System.err.println("source is " + source); } If I switch the comments and run the manual resource lookup, it works fine. Should the @Resource annotation work like this, when used in a contextInitalized method? Appserver is WAS 7.0.0.5, if it should work then I guess it's a bug? Can anyone confirm?

  • Inherit all methods of object (including "constructor"), but modify some of them.

    - by Kirzilla
    Hello, Let's imagine that we have object Animal $.Animal = function(options) { this.defaults = { name : null } this.options = $.extend(this.defaults, options); } $.Animal.prototype.saySomething = function() { alert("I'm animal!"); } Now I'd like to create Cat object. It is absolutely similar to $.Annimal, but method saySomething() will look like this one... $.Cat.prototype.saySomething = function() { alert("I'm cat!"); } How can I inherit from Animal to create new object Cat and redefine saySomething() method? Thank you.
