  • NETBEANS JAVADB - How do I integrate a JavaDB DataBase into my main Java Package

    - by Stefanos Kargas
    JAVA I am working on a desktop application which uses JavaDB. I am using NetBeans 6.8 and JDK 6 Update 20 I created the database I need and connected to it through my application using ClientDriver: String driver = "org.apache.derby.jdbc.ClientDriver"; String connectionURL = "jdbc:derby://localhost:1527/myDB;create=true;user=user;password=pass"; try { Class.forName(driver); } catch (java.lang.ClassNotFoundException e) { e.printStackTrace(); } try { schedoDBConnection = DriverManager.getConnection(connectionURL); } catch (Exception e) { e.printStackTrace(); } This works fine. But in that case the service of the database comes from NetBeans. If I move my application to another PC I won't be able to access my database. How can I integrate my JavaDB into my application?

  • How to efficiently handle Where and OrderBy clauses

    - by Goran
    My business layer passes all the required information to UI layer. From what I have read, in general, best practice is to send fetched data to UI layer, and to avoid passing queries like ObjectQuery. My problem with this approach is next: If I am to make a flexible business layer, then I should allow UI to sort the data anyway it requires. Fetching sorted data from database, and then resorting them in UI is kind of bad practice for me, so the only way is to somehow So what are my options? Is there a way to make it like this: public void OrderByMethod(params ...) { .... } so I can call it like this: OrderByMethod(MyEntity.Property1, MyEntity.Property2 descending....); Thanks, Goran

  • How do I keep a scanner from throwing exceptions when the wrong type is entered? (java)

    - by David
    Here's some sample code: import java.util.Scanner; class In { public static void main (String[]arg) { Scanner in = new Scanner (System.in) ; System.out.println ("how many are invading?") ; int a = in.nextInt() ; System.out.println (a) ; } } if i run the program and give it an int like 4then everything goes fine. if, on the other hand, i answer too many it doesn't laugh at my funny joke. instead i get this: (as expected) Exception in thread "main" java.util.InputMismatchException at java.util.Scanner.throwFor(Scanner.java:819) at java.util.Scanner.next(Scanner.java:1431) at java.util.Scanner.nextInt(Scanner.java:2040) at java.util.Scanner.nextInt(Scanner.java:2000) at In.main(In.java:9) is there a way so that i can make it so that it either ignores entries that aren't ints or re prompts with "how many are invading?"? i'd like to know how to do both of these.

  • Track each request to the website

    - by stacker
    I want to save each request to the website. In general I want to include the following information: User IP, The web site url. Response time, response success-failed status. Is it reasonable to collect the 1 and 2 in the same action? (like same HttpModule)? Do you know about any existing structure that I can follow that track every request/response-status to the website? The data need to be logged to sql server.

  • What are the virtues of using XML comments in .NET?

    - by Michal Czardybon
    I can't understand the virtues of using XML comments. I know they can be converted into nice documentation external to the code, but the same can be achieved with the much more concise DOxygen syntax. In my opinion the XML comments are wrong, because: They obfuscate the comments and the code in general. (They are more difficult to read by humans). Less code can be viewed on a single screen, because "summary" and "/summary" take additional lines. They suggest that all method parameters have to be commented, whereas 90% of them are obvious and SHOULD be left not commented. The only problem I have with this is that my point of view seems to be in minority. Why?

  • How to make a thread try to reconnect to the Database x times using JDBCTemplate

    - by gillJ
    Hi, I have a single thread trying to connect to a database using JDBCTemplate as follows: JDBCTemplate jdbcTemplate = new JdbcTemplate(dataSource); try{ jdbcTemplate.execute(new CallableStatementCreator() { @Override public CallableStatement createCallableStatement(Connection con) throws SQLException { return con.prepareCall(query); } }, new CallableStatementCallback() { @Override public Object doInCallableStatement(CallableStatement cs) throws SQLException { cs.setString(1, subscriberID); cs.execute(); return null; } }); } catch (DataAccessException dae) { throw new CougarFrameworkException( "Problem removing subscriber from events queue: " + subscriberID, dae); } I want to make sure that if the above code throws DataAccessException or SQLException, the thread waits a few seconds and tries to re-connect, say 5 more times and then gives up. How can I achieve this? Also, if during execution the database goes down and comes up again, how can i ensure that my program recovers from this and continues running instead of throwing an exception and exiting?

  • Good workflow with emacs+swank+slime+clojure?

    - by grm
    I just wanted opinion on good workflow using the emacs environment with clojure+swank+slime. I often find myself doing very repetitive keycommands and wonder if there is an obvious better way. I include swank with lein and start my project using lein swank from shell. Then I connect with emacs and do the correct use commands so that I can start to use (run-tests ). Then I do some coding and then want to test. To run the test I need to change buffer in emacs to the swank-repl C-x o, then I need to go to the prompt M-, then repeat the command M-p, then enter, maybe with an exception, then back to the code buffer and continue all over again with all the emacs commands. I find it a bit repetitive. I guess the solution would be to start hack on emacs and maybe add a shortcut for doing this repetitive task, but I would love to hear some suggestions because I can't be the only one who find this tedious?

  • java.lang.UnsupportedClassVersionError in eclipse

    - by Derek
    Hi all, I am not a Java programmer really, so I am posting this question. The exception is being thrown java.lang.UnsupportedClassVersionError in my main class in an eclipse project. If I comment out the imports that this class has, it compiles and runs fine. If I put the imports back in, it does not work. Does this mean that the libraries I am importing were compiled with a newer or older version of java than I have? when i do java -version on the system i get 1.5_07 I could've sworn this was actually working last week, but maybe some setting in eclipse got tweaked? Is the Java Build Path in eclipse what I need to look for to check the JRE and compiler versions?

  • ASP.NET MVC 2: Deserialize SPROC Response

    - by dcolumbus
    I need to ask a general question. I don't have the code in front of me because I'm writing this on my iPhone. I have a Class that represents a certain XML schema. I have a SPROC that returns this XML. What I need to do is deserialize the XML to this Class. XML: <xml> <person> <firstName>Bob</firstName> <lastName>Robby</lastName> </person> </xml> I need to deserialize this XML into the custom Person Class so I can loop through this Model and spit it out in the View. I'm sure there's some kind of casting involved, I just don't know how to do it.

  • Trying to Unit Test A Class That Makes DB Queries Using Hibernate And Can't Get Session Created...

    - by Jared Michaels
    I am trying to implement JUnit tests for a class that performs DB queries using Hibernate. When I create the class under test, I get access to the session through the factory by doing the following: InitialContext context = new InitialContext(); sessionFactory = (SessionFactory) context.lookup(hibernateContext); This works fine when I deploy this to JBoss 5.1. I am trying to figure out how to get this to work with my JUnit test. I keep getting an exception stating that I "Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial". I've searched high and low but haven't been able to find any information about what specifically I need to do to get this to work. I am not using Spring or any frameworks, just plain old Java and JUnit.

  • Best practice with respect to NPE and multiple expressions on single line

    - by JRL
    I'm wondering if it is an accepted practice or not to avoid multiple calls on the same line with respect to possible NPEs, and if so in what circumstances. For example: getThis().doThat(); vs Object o = getThis(); o.doThat(); The latter is more verbose, but if there is an NPE, you immediately know what is null. However, it also requires creating a name for the variable and more import statements. So my questions around this are: Is this problem something worth designing around? Is it better to go for the first or second possibility? Is the creation of a variable name something that would have an effect performance-wise? Is there a proposal to change the exception message to be able to determine what object is null in future versions of Java ?

  • Property in a Windows Forms form class only accessable after Load event

    - by Spooky2010
    I'm 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 ?

  • I Clean Solution'd my Winform App and now it's broken...

    - by Refracted Paladin
    I have a Winform App that uses a 3rd Party Library of Controls, DevExpress. I also created a bunch of Controls myself, extending those controls. Everything has been working fine when all of a sudden I opened VS today and on the Design Page all my extended controls were missing. I then tried rebuilding to no avail. Then I tried Cleaning and Rebuilding and made it even worse. Now I have tons(520) of erros stating things like -- Error 179 The name 'datBirthDate' does not exist in the current context D:\Documents\Visual Studio 2008\Projects\MatrixReloaded\MatrixReloaded\Controls\Member\ucGeneral.cs 339 17 MatrixReloaded also if I try to open a form or user control in Design Mode I first get this -- could not find type, "MyType" please make sure that the assembly that contains this type is referenced and then, if I click Ignore and Continue I get this for all Forms and Contros when I try and look at them in Design Mode -- Exception of type System.OutOfMemoryException was thrown Help!?!? When I googled I came across mostly references to VS 2003...I am on 2008 sp1.

  • Ramifications of CheckForIllegalCrossThreadCalls=false

    - by Ron Skufca
    I recently updated an application from VS2003 to VS2008 and I knew I would be dealing with a host of "Cross-thread operation not valid: Control 'myControl' accessed from a thread other than the thread it was created on" I am handling this in what I beleive is the correct way (see code sample below). I am running into numerous controls that are going to need a similar fix. Not wanting to have similar code for every label, textbox etc.. that are being accessed by a non UI thread. What are the ramifications of just setting the CheckForIllegalCrossThreadCalls = false for the entire app? I found a CodeProject article with various workarounds and a warning at the bottom to NOT set the property. I am looking for other opinions/experiences on this issue. private void ShowStatus(string szStatus) { try { if (this.statusBar1.InvokeRequired) { BeginInvoke(new MethodInvoker(delegate() { ShowStatus(szStatus); })); } else { statusBar1.Panels[0].Text = szStatus; } } catch (Exception ex) { LogStatus.WriteErrorLog(ex, "Error", "frmMNI.ShowStatus()"); } }

  • Fastest way of converting a quad to a triangle strip?

    - by Tina Brooks
    What is the fastest way of converting a quadrilateral (made up of foyr x,y points) to a triangle strip? I'm well aware of the general triangulation algorithms that exist, but I need a short, well optimized algorithm that deals with quadrilaterals only. My current algorithm does this, which works for most quads but still gets the points mixed up for some: #define fp(f) bounds.p##f /* Sort four points in ascending order by their Y values */ point_sort4_y(&fp(1), &fp(2), &fp(3), &fp(4)); /* Bottom two */ if (fminf(-fp(1).x, -fp(2).x) == -fp(2).x) { out_quad.p1 = fp(2); out_quad.p2 = fp(1); } else { out_quad.p1 = fp(1); out_quad.p2 = fp(2); } /* Top two */ if (fminf(-fp(3).x, -fp(4).x) == -fp(3).x) { out_quad.p3 = fp(3); out_quad.p4 = fp(4); } else { out_quad.p3 = fp(4); out_quad.p4 = fp(3); }

  • Is there an easy way to sign a C++ CLI assembly in VS 2010?

    - by jyoung
    Right now I am setting the Linker/Advanced/KeyFile option. I am getting the "mt.exe : general warning 810100b3: is a strong-name signed assembly and embedding a manifest invalidates the signature. You will need to re-sign this file to make it a valid assembly.". Reading from the web, it sounds like I have to set the delay signing option, download the SDK, and run sn.exe as a post build event. Surely there must be an easier way to do this common operation in VS2010?
