  • How to prevent unit test from using util from test project?

    - by calucier
    I am using eclipse and I have two projects, project1 and project1-test. Below is the example layout of my projects: project1 -src --my.package ----MyClass.java --my.package.util ----util.java project1-test -src --my.package ----MyClassTest.java --my.package.util ----util.java MyClass.java makes a static call to the util.java in project1. MyClassTests.java is testing MyClass.java. When the test class runs, it fails and complains that MyClass.java is referencing a method in util.java that doesn't exist. Under project1, the method being referenced exists in util.java but under project1-test, the method doesn't. When I run MyClassTests.java, the util.java that is being referenced from MyClass.java is from project1-test when it should be project1. Is there some way to make MyClass.java not reference util.java from project1-test when running MyClassTest.java?

  • JAVA_OPTS -XX:+PrintGCDetails affect on performance?

    - by brad
    Does anyone know if the PrintGCDetails affects java performance much? I've been monitoring our java garbage collecting on a staging server with the same setup as the production server. I assumed it was safe to say that I shouldn't have this enabled on production but I don't know if there's really any affect on performance.

  • java.sql.SQLException: Parameter number X is not an OUT parameter

    - by Frederik
    Hi guys, I'm struggling with getting the result OUT variable from a MySQL stored procedure. I get the following error: java.sql.SQLException: Parameter number 3 is not an OUT parameter The stored procedure looks like this: CREATE DEFINER=`cv_admin`@`localhost` PROCEDURE `CheckGameEligibility`( IN gID INT(10), IN uID INT(10), OUT result TINYINT(1) ) BEGIN # Do lots of stuff, then eventually: SET result = 1; END My java function takes an array of strings* and creates the CallableStatement object dynamically: public static int callAndReturnResult( String sql , String[] values ) { int out = 0 ; try { // construct the SQL. Creates: CheckGameEligibility(?, ?, ?) sql += "(" ; for( int i = 0 ; i < values.length ; i++ ) { sql += "?, " ; } sql += "?)" ; System.out.println( "callAndReturnResult("+sql+"): constructed SQL: " + sql ); // Then the statement CallableStatement cstmt = DB.prepareCall( sql ); for( int i = 0 ; i < values.length ; i++ ) { System.out.println( " " + (i+1) + ": " + values[ i ] ) ; cstmt.setString(i+1, values[ i ] ); } System.out.println( " " + (values.length+1) + ": ? (OUT)" ) ; cstmt.registerOutParameter( values.length + 1 , Types.TINYINT ); cstmt.execute(); out = cstmt.getInt( values.length ); cstmt.close(); } catch( Exception e ) { System.out.println( "*** db trouble: callAndReturnResult(" + sql + " failed: " + e ); e.printStackTrace() ; } return out ; } *) I suppose I should be using an int array instead of a string array, but it doesn't seem to be what the error message was about. Anyway, here's the output it generates: callAndReturnResult(CheckGameEligibility(?, ?, ?)): constructed SQL: CheckGameEligibility(?, ?, ?) 1: 57 2: 29 3: ? (OUT) *** db trouble: callAndReturnResult(CheckGameEligibility(?, ?, ?) failed: java.sql.SQLException: Parameter number 3 is not an OUT parameter at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:1075) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:989) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:984) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:929) at com.mysql.jdbc.CallableStatement.checkIsOutputParam(CallableStatement.java:692) at com.mysql.jdbc.CallableStatement.registerOutParameter(CallableStatement.java:1847) at org.apache.commons.dbcp.DelegatingCallableStatement.registerOutParameter(DelegatingCallabl>eStatement.java:92) at Tools.callAndReturnResult(Tools.java:156) Any ideas what might be the problem? :) Thanks in advance!

  • What's your "best practice" for the first Java EE Spring project?

    - by cringe
    I'm currently trying to get into the Java EE development with the Spring framework. As I'm new to Spring, it is hard to imaging how a good running project should start off. Do you have any best practices, tipps or major DO NOTs for a starter? How did you start with Spring - big project or small tutorial-like applications? Which technology did you use right away: AOP, complex Hibernate...

  • MVC Entity Framework Model not returning correct data

    - by quagland
    Hi, Run into a strange problem while writing an ASP.NET MVC site. I have a view in my SQL Server database that returns a few date ranges. The view works fine when running the query in SSMS. When the view data is returned by the Entity Framework Model, It returns the correct number of rows but some of the rows are duplicated. Here is an example of what I have done: SQL Server code: CREATE TABLE [dbo].[A]( [ID] [int] NOT NULL, [PhID] [int] NULL, [FromDate] [datetime] NULL, [ToDate] [datetime] NULL, CONSTRAINT [PK_A] PRIMARY KEY CLUSTERED ([ID] ASC)) ON [PRIMARY] go CREATE TABLE [dbo].[B]( [PhID] [int] NOT NULL, [FromDate] [datetime] NULL, [ToDate] [datetime] NULL, CONSTRAINT [PK_B] PRIMARY KEY CLUSTERED ( [PhID] ASC )) ON [PRIMARY] go CREATE VIEW C as SELECT A.ID, CASE WHEN A.PhID IS NULL THEN A.FromDate ELSE B.FromDate END AS FromDate, CASE WHEN A.PhID IS NULL THEN A.ToDate ELSE B.ToDate END AS ToDate FROM A LEFT OUTER JOIN B ON A.PhID = B.PhID go INSERT INTO B (PhID, FromDate, ToDate) VALUES (100, '20100615', '20100715') INSERT INTO A (ID, PhID, FromDate, ToDate) VALUES (1, NULL, '20100101', '20100201') INSERT INTO A (ID, PhID, FromDate, ToDate) VALUES (1, 100, '20100615', '20100715') INSERT INTO B (PhID, FromDate, ToDate) VALUES (101, '20101201', '20101231') INSERT INTO A (ID, PhID, FromDate, ToDate) VALUES (2, NULL, '20100801', '20100901') INSERT INTO A (ID, PhID, FromDate, ToDate) VALUES (2, 101, '20101201', '20101231') So now, if you select all from C, you get 4 separate date ranges In the Entity Framework Model (which I call 'Core'), the view 'C' is added. in MVC Controller: public class HomeController : Controller { public ActionResult Index() { CoreEntities db = new CoreEntities(); var clist = from c in db.C select c; return View(clist.ToList()); } } in MVC View: @model List<RM.Models.C> @{ foreach (RM.Models.C c in Model) { @String.Format("{0:dd-MMM-yyyy}", c.FromDate) <span>-</span> @String.Format("{0:dd-MMM-yyyy}", c.ToDate) <br /> } } When I run all this, it outputs this: 01-Jan-2010 - 01-Feb-2010 01-Jan-2010 - 01-Feb-2010 01-Aug-2010 - 01-Sep-2010 01-Aug-2010 - 01-Sep-2010 When it should do this (this is what the view returns): 01-Jan-2010 - 01-Feb-2010 15-Jun-2010 - 15-Jul-2010 01-Aug-2010 - 01-Sep-2010 01-Dec-2010 - 31-Dec-2010 Also, I've run the SQL profiler over it and according to that, the query being executed is: SELECT [Extent1].[ID] AS [ID], [Extent1].[FromDate] AS [FromDate], [Extent1].[ToDate] AS [ToDate] FROM (SELECT [C].[ID] AS [ID], [C].[FromDate] AS [FromDate], [C].[ToDate] AS [ToDate] FROM [dbo].[C] AS [C]) AS [Extent1] Which returns the correct data So it seems that the entity framework is doing something to the data in the meantime. To me, everything looks fine! Have I missed something? Cheers, Ben

  • Programming Java 7 in Eclipse

    - by reprogrammer
    I installed JDK 7 and Eclipse 3.6M6. Then, I added JRE 7 as a new JRE execution environment in Eclipse, and set the compiler compliance level to Java 7. I can compile the following piece of code through command line using the javac that comes with JDK 7. import java.util.HashMap; import java.util.Map; public class Try { public static void main(String[] args) { Map<Integer, String> map = new HashMap<>(); } } But, Eclipse gives the following error messages. Incorrect number of arguments for type HashMap; it cannot be parameterized with arguments Try.java /TryJava7/src line 7 Java Problem Syntax error on token "<", ? expected after this token Try.java /TryJava7/src line 7 Java Problem Even though I've set the compliance level of the compiler to Java 7, it looks like Eclipse doesn't understand Java7 syntax yet. Is it possible to play with Java 7 in Eclipse?

  • Is this error caused by a 64-bit library being accessed by a Java program running in a 32-bit JVM?

    - by Mike
    I'm trying to create a simple Java app that uses JNI to call some native functions. I've followed the examples in the JNI Programming Guide and can't seem to get them to work. I have the following Hello World program, written in Java: class HelloWorld { private native void print(); public static void main(String [] args) { new HelloWorld().print(); } static { System.load("/home/mike/Desktop/libHelloWorld.so"); } } I compile it using javac HelloWorld.java, just like normal. Then I run javah -jni HelloWorld, and finally the following: gcc34 -shared -fpic -o libHelloWorld.so -I/<path to JDK>/include -I/<path to JDK>/include/linux HelloWorld.c gcc34 is the name of the GCC program on my machine here at work (I don't control that) and I obviously place the real path to the JDK in that command. When I run my program, using the standard java HelloWorld, I get an error saying the following: Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/mike/Desktop/libHelloWorld.so: /home/mike/Desktop/libHelloWorld.so: wrong ELF class: ELFCLASS64 (Possible causes: architecture word width mismatch) at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1778) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1674) at java.lang.Runtime.load0(Runtime.java:770) at java.lang.System.load(System.java:1003) at HelloWorld.<clinit>(HelloWorld.java:8) Could not find the main class: HelloWorld. Program will exit. I know I'm running a 32-bit JVM (and unfortunately, as of right now, I'm not allowed to get a 64-bit JVM). I tried telling GCC to compile in 32-bit mode using the "-m32" option, but we don't have (and again, can't get) what we need for that. Does this sound like a 32/64-bit conflict or something else?

  • using ResultSet.Previous method not working in Java using .mdb file OBDC

    - by jsonnie
    Hello, I'm currently having an issue with my open result set not working how I believe it should. The only function that is currently working is the next() method, nothing else will work.

If someone could point me in the right direction it would be truly appreciated.

  • Write binary stream to browser using PHP

    - by Dave Jarvis
    Background Trying to stream a PDF report written using iReport through PHP to the browser. The general problem is: how do you write binary data to the browser using PHP? Working Code The following code does the job, but (for many reasons) it is not as efficient as it should be (the code writes a file then sends the file contents the browser). // Load the MySQL database driver. // java( 'java.lang.Class' )->forName( 'com.mysql.jdbc.Driver' ); // Attempt a database connection. // $conn = java( 'java.sql.DriverManager' )->getConnection( "jdbc:mysql://localhost:3306/climate?user=$user&password=$password" ); // Extract parameters. // $params = new java('java.util.HashMap'); $params->put('DistrictCode', '101'); $params->put('StationCode', '0066'); $params->put('CategoryCode', '010'); // Use the fill manager to produce the report. // $fm = java('net.sf.jasperreports.engine.JasperFillManager'); $pm = $fm->fillReport($report, $params, $conn); header('Cache-Control: no-cache private'); header('Content-Description: File Transfer'); header('Content-Disposition: attachment, filename=climate-report.pdf'); header('Content-Type: application/pdf'); header('Content-Transfer-Encoding: binary'); header('Content-Length: ' . strlen( $result ) ); $path = realpath( "." ) . "/output.pdf"; $em = java('net.sf.jasperreports.engine.JasperExportManager'); $result = $em->exportReportToPdfFile($pm,$path); readfile( $path ); $conn->close(); Non-working Code To remove the slight redundancy (i.e., write directly to the browser), the following code looks like it should work, but it does not: $em = java('net.sf.jasperreports.engine.JasperExportManager'); $result = $em->exportReportToPdf($pm); header('Content-Length: ' . strlen( $result ) ); echo $result; Content is sent to the browser, but the file is corrupt (it begins with the PDF header) and cannot be read by any PDF reader. Question How can I take out the middle step of writing to the file and write directly to the browser so that the PDF is not corrupted? Thank you!

  • Android - BroadcastReceiver CONNECTIVITY ACTION

    - by Marc Ortiz
    in my project there's a service that listens for changes in the connectivity. When wifi is switched off to on then it gets called. The problem it's that i'm using a fragment and inside a fragment there's a button with the setonclicklistener(); and onclick(); SOMETIMES when i touch the button then the service receives an intent that the connectivity has changed (the method gets called without any reason...). Here's the code of my fragment activity for the viewpager layout: public static class FragmentSelection extends Fragment { int mNum; static FragmentSelection newInstance(int num) { FragmentSelection f = new FragmentSelection(); // Supply num input as an argument. Bundle args = new Bundle(); args.putInt("num", num); f.setArguments(args); return f; } /** * When creating, retrieve this instance's number from its arguments. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mNum = (getArguments() != null ? getArguments().getInt("num") : 1) + 1; } @Override public View onCreateView(LayoutInflater inflater,

  • Java InputStream encoding/charset

    Running the following (example) code import java.io.*; public class test { public static void main(String[] args) throws Exception { byte[] buf = {-27}; InputStream is = new ByteArrayInputStream(buf); BufferedReader r = new BufferedReader(new InputStreamReader(is, "ISO-8859-1")); String s = r.readLine(); System.out.println("test.java:9 [byte] (char)" + (char)s.getBytes()[0] + " (int)" + (int)s.getBytes()[0]); System.out.println("test.java:10 [char] (char)" + (char)s.charAt(0) + " (int)" + (int)s.charAt(0)); System.out.println("test.java:11 string below"); System.out.println(s); System.out.println("test.java:13 string above"); } } gives me this output test.java:9 [byte] (char)? (int)63 test.java:10 [char] (char)? (int)229 test.java:11 string below ? test.java:13 string above How do I retain the correct byte value (-27) in the line-9 printout? And consequently receive the expected output of the System.out.println(s) command (å).

  • How to use Comparator in Java to sort

    - by Dan
    I learned how to use the comparable but I'm having difficulty with the Comparator. I am having a error in my code: Exception in thread "main" java.lang.ClassCastException: New.People cannot be cast to java.lang.Comparable at java.util.Arrays.mergeSort(Unknown Source) at java.util.Arrays.sort(Unknown Source) at java.util.Collections.sort(Unknown Source) at New.TestPeople.main(TestPeople.java:18) Here is my code: import java.util.Comparator; public class People implements Comparator{ private int id; private String info; private double price; public People(int newid, String newinfo, double newprice){ setid(newid); setinfo(newinfo); setprice(newprice); } public int getid() { return id; } public void setid(int id) { this.id = id; } public String getinfo() { return info; } public void setinfo(String info) { this.info = info; } public double getprice() { return price; } public void setprice(double price) { this.price = price; } public int compare(Object obj1, Object obj2) { Integer p1 = ((People)obj1).getid(); Integer p2 = ((People)obj2).getid(); if (p1 p2 ){ return 1; } else if (p1 < p2){ return -1; } else return 0; } } import java.util.ArrayList; import java.util.Collections; public class TestPeople { public static void main(String[] args) { ArrayList peps = new ArrayList(); peps.add(new People(123, "M", 14.25)); peps.add(new People(234, "M", 6.21)); peps.add(new People(362, "F", 9.23)); peps.add(new People(111, "M", 65.99)); peps.add(new People(535, "F", 9.23)); Collections.sort(peps); for(int i=0;i I believe it has to do something with the casting in the compare method but I was playing around with it and still could not find the solution

  • Java conditional compilation: how to prevent code chunks to be compiled?

    - by khachik
    My project requires Java 1.6 for compilation and running. Now I have a requirement to make it working with Java 1.5 (from the marketing side). I want to replace method body (return type and arguments remain the same) to make it compiling with Java 1.5 without errors. Details: I have an utility class called OS which encapsulates all OS-specific things. It has a method public static void openFile(java.io.File file) throws java.io.IOException { // open the file using java.awt.Desktop ... } to open files like with double-click (start Windows command or open Mac OS X command equivalent). Since it cannot be compiled with Java 1.5, I want to exclude it during compilation and replace by another method which calls run32dll for Windows or open for Mac OS X using Runtime.exec. Question: How can I do that? Can annotations help here? Note: I use ant, and I can make two java files OS4J5.java and OS4J6.java which will contain the OS class with the desired code for Java 1.5 and 1.6 and copy one of them to OS.java before compiling (or an ugly way - replace the content of OS.java conditionally depending on java version) but I don't want to do that, if there is another way. Elaborating more: in C I could use ifdef, ifndef, in Python there is no compilation and I could check a feature using hasattr or something else, in Common Lisp I could use #+feature. Is there something similar for Java? Found this post but it doesn't seem to be helpful. Any help is greatly appreciated. kh.

  • Why doesn't the spring @Autowire work with java generics

    - by testing123
    Inspired by spring data awesomeness I wanted to create a abstract RESTController that I could extend for a lot of my controllers. I created the following class: @Controller public abstract class RESTController<E, PK extends Serializable, R extends PagingAndSortingRepository<E, PK>> { @Autowired private R repository; @RequestMapping(method=RequestMethod.GET, params={"id"}) @ResponseBody public E getEntity(@RequestParam PK id) { return repository.findOne(id); } ... } I was hoping that the generics would allow me to @Autowire in the repository but I get the following error: SEVERE: Allocate exception for servlet appServlet org.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type [org.springframework.data.repository.PagingAndSortingRepository] is defined: expected single matching bean but found 3: [groupRepository, externalCourseRepository, managedCourseRepository] at org.springframework.beans.factory.support.DefaultListableBeanFactory.doResolveDependency(DefaultListableBeanFactory.java:800) at org.springframework.beans.factory.support.DefaultListableBeanFactory.resolveDependency(DefaultListableBeanFactory.java:707) at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:478) at org.springframework.beans.factory.annotation.InjectionMetadata.inject(InjectionMetadata.java:87) at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor.postProcessPropertyValues(AutowiredAnnotationBeanPostProcessor.java:284) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.populateBean(AbstractAutowireCapableBeanFactory.java:1106) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:517) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:456) at org.springframework.beans.factory.support.AbstractBeanFactory$1.getObject(AbstractBeanFactory.java:294) I understand what the error is telling me, there is more than one match for the @Autowire. I am confused because I thought by creating the following controller it would work: @Controller @RequestMapping(value="/managedCourse") public class ManagedCourseController extends RESTController<ManagedCourse, Long, ManagedCourseRepository> { ... } This is easy enough to work around by doing having a method like this in the RESTController: protected abstract R getRepository(); and then doing this in your implementing class: @Autowired private ManagedCourseRepository repository; @Override protected ManagedCourseRepository getRepository() { return repository; } I was just wondering if someone had any thoughts of how I could get this to work.

  • Java EE @ No Fluff Just Stuff Tour

    - by reza_rahman
    If you work in the US and still don't know what the No Fluff Just Stuff (NFJS) Tour is, you are doing yourself a very serious disfavor. NFJS is by far the cheapest and most effective way to stay up to date through some world class speakers and talks. This is most certainly true for US enterprise Java developers in particular. Following the US cultural tradition of old-fashioned roadshows, NFJS is basically a set program of speakers and topics offered at major US cities year round. Many now famous world class technology speakers can trace their humble roots to NFJS. Via NFJS you basically get to have amazing training without paying for an expensive venue, lodging or travel. The events are usually on the weekends so you don't need to even skip work if you want (a great feature for consultants on tight budgets and deadlines). I am proud to share with you that I recently joined the NFJS troupe. My hope is that this will help solve the lingering problem of effectively spreading the Java EE message here in the US. For NFJS I hope my joining will help beef up perhaps much desired Java content. In any case, simply being accepted into this legendary program is an honor I could have perhaps only dreamed of a few years ago. I am very grateful to Jay Zimmerman for seeing the value in me and the Java EE content. The current speaker line-up consists of the likes of Neal Ford, Venkat Subramaniam, Nathaniel Schutta, Tim Berglund and many other great speakers. I actually had my tour debut on April 4-5 with the NFJS New York Software Symposium - basically a short train commute away from my home office. The show is traditionally one of the smaller ones and it was not that bad for a start. I look forward to doing a few more in the coming months (more on that a bit later). I had four talks back to back (really my most favorite four at the moment). The first one was a talk on JMS 2 - some of you might already know JMS is one of my most favored Java EE APIs. The slides for the talk are posted below: What’s New in Java Message Service 2 from Reza Rahman The next talk I delivered was my Cargo Tracker/Java EE + DDD talk. This talk basically overviews DDD and describes how DDD maps to Java EE using code examples/demos from the Cargo Tracker Java EE Blue Prints project. Applied Domain-Driven Design Blue Prints for Java EE from Reza Rahman The third talk I delivered was our flagship Java EE 7/8 talk. As you may know, currently the talk is basically about Java EE 7. I'll probably slowly evolve this talk to gradually transform it into a Java EE 8 talk as we move forward (I'll blog about that separately shortly). The following is the slide deck for the talk: JavaEE.Next(): Java EE 7, 8, and Beyond from Reza Rahman My last talk for the show was my JavaScript+Java EE 7 talk. This talk is basically about aligning EE 7 with the emerging JavaScript ecosystem (specifically AngularJS). The slide deck for the talk is here: JavaScript/HTML5 Rich Clients Using Java EE 7 from Reza Rahman Unsurprisingly this talk was well-attended. The demo application code is posted on GitHub. The code should be a helpful resource if this development model is something that interests you. Do let me know if you need help with it but the instructions should be fairly self-explanatory. My next NFJS show is the Central Ohio Software Symposium in Columbus on June 6-8 (sorry for the late notice - it's been a really crazy few weeks). Here's my tour schedule so far, I'll keep you up-to-date as the tour goes forward: June 6 - 8, Columbus Ohio. June 24 - 27, Denver Colorado (UberConf) - my most extensive agenda on the tour so far. July 18 - 20, Austin Texas. I hope you'll take this opportunity to get some updates on Java EE as well as the other awesome content on the tour?
