  • Play Framework: Error getting sequence nextval using H2 in-memory database

    - by alexhanschke
    As the title suggests, I get an error running Play 2.0.1 Tests using a FakeApplication w/ H2 in memory. I set up a basic unit test: public class ModelTest { @Test public void checkThatIndustriesExist() { running(fakeApplication(inMemoryDatabase()), new Runnable() { public void run() { Industry industry = new Industry(); industry.name = "Some name"; industry.shortname = "some-name"; industry.save(); assertThat(Industry.find.all()).hasSize(1); } }); } Which yields the following exception: [info] test.ModelTest [error] Test test.ModelTest.checkThatIndustriesExist failed: Error getting sequence nextval [error] at com.avaje.ebean.config.dbplatform.SequenceIdGenerator.getMoreIds(SequenceIdGenerator.java:213) [error] at com.avaje.ebean.config.dbplatform.SequenceIdGenerator.loadMoreIds(SequenceIdGenerator.java:163) [error] at com.avaje.ebean.config.dbplatform.SequenceIdGenerator.nextId(SequenceIdGenerator.java:118) [error] at com.avaje.ebeaninternal.server.deploy.BeanDescriptor.nextId(BeanDescriptor.java:1218) [error] at com.avaje.ebeaninternal.server.persist.DefaultPersister.setIdGenValue(DefaultPersister.java:1304) [error] at com.avaje.ebeaninternal.server.persist.DefaultPersister.insert(DefaultPersister.java:403) [error] at com.avaje.ebeaninternal.server.persist.DefaultPersister.saveEnhanced(DefaultPersister.java:345) [error] at com.avaje.ebeaninternal.server.persist.DefaultPersister.saveRecurse(DefaultPersister.java:315) [error] at com.avaje.ebeaninternal.server.persist.DefaultPersister.save(DefaultPersister.java:282) [error] at com.avaje.ebeaninternal.server.core.DefaultServer.save(DefaultServer.java:1577) [error] at com.avaje.ebeaninternal.server.core.DefaultServer.save(DefaultServer.java:1567) [error] at com.avaje.ebean.Ebean.save(Ebean.java:538) [error] at play.db.ebean.Model.save(Model.java:76) [error] at test.ModelTest$1.run(ModelTest.java:24) [error] at play.test.Helpers.running(Helpers.java:277) [error] at test.ModelTest.checkThatIndustriesExist(ModelTest.java:21) [error] ...

  • Java (JSP): repeating the contentType header in a "sub-jsp"

    - by Webinator
    What happens when headers are repeated in a .jsp you include in another .jsp? For example if example.jsp starts with this: <?xml version="1.0" encoding="UTF-8"?> <jsp:root version="2.0" xmlns:jsp="http://java.sun.com/JSP/Page"> <jsp:directive.page contentType="text/html; charset=UTF-8" /> <div class="content"> <jsp:include page="support-header.jsp"/> ... (it includes support-header.jsp) And then support-header.jsp starts also with this: <?xml version="1.0" encoding="UTF-8"?> <jsp:root version="2.0" xmlns:jsp="http://java.sun.com/JSP/Page"> <jsp:directive.page contentType="text/html; charset=UTF-8" /> ... Is that a problem? Is it bad practice? What does concretely happen when you repeat several times a header that only corresponds to one header in the resulting .html page?

  • Coding a parser for a domain specific language in Java

    - by Bruno Rothgiesser
    We want to design a simple domain specific language for writing test scripts to automatically test a XML-based interface of one of our applications. A sample test would be: Get an input XML file from network shared folder or subversion repository Import the XML file using the interface Check if the import result message was successfull Export the XML corresponding to the object that was just imported using the interface and check if it correct. If the domain specific language can be declarative and its statements look as close as my sentences in the sample above as possible, it will be awesome because people won't necessarily have to be programmers to understand/write/maintain the tests. Something like: newObject = GET FILE "http://svn/repos/template1.xml" reponseMessage = IMPORT newObject newObjectID = GET PROPERTY '/object/id/' FROM responseMessage (..) But then I'm not sure how to implement a simple parser for that languange in Java. Back in school, 10 years ago, I coded a language parser using Lex and Yacc for the C language. Maybe an approach would be to use some equivalent for Java? Or, I could give up the idea of having a declarative language and choose an XML-based language instead, which would possibly be easier to create a parser for? What approach would you recommend?

  • java converting int to short

    - by changed
    Hi I am calculating 16 bit checksum on my data which i need to send to server where it has to recalculate and match with the provided checksum. Checksum value that i am getting is in int but i have only 2 bytes for sending the value.So i am casting int to short while calling shortToBytes method. This works fine till checksum value is less than 32767 thereafter i am getting negative values. Thing is java does not have unsigned primitives, so i am not able to send values greater than max value of signed short allowed. How can i do this, converting int to short and send over the network without worrying about truncation and signed & unsigned int. Also on both the side i have java program running. private byte[] shortToBytes(short sh) { byte[] baValue = new byte[2]; ByteBuffer buf = ByteBuffer.wrap(baValue); return buf.putShort(sh).array(); } private short bytesToShort(byte[] buf, int offset) { byte[] baValue = new byte[2]; System.arraycopy(buf, offset, baValue, 0, 2); return ByteBuffer.wrap(baValue).getShort(); }

  • Log in using Java where server's authentication could be sso or web applcation container's basic

    - by Ed
    Hi, I have a situation where ideally I want to be able to log-in to a secure area using a Java application. I would like to make an HTTP request and check the response to see if I need to do some kind of authenication before I can actually get the response expected, instead of effectively some login page. The complication is that the server that responds will not always be the same - the user of the Java app specifies the URL - and the server may be using some kind of single sign on authentication or the web container's. I don't know the field names for the username and password fields or the action of the form, is there a simple way to obtain this kind of information from the URL? I see the URLConnection object has methods getPermission() which has a method getActions() but are not suitable, anything that might be? I guess example things I am looking to determine: Does the response require authentication? If so; what type / which servlet? e.g. j_security_check, josso single sign on, ... And then some way of authenticating the client And finally managing the state of the authenticated user for other requests Do I need to know the attributes of the login form before attemping to login? And then, is the onoly way of verifying permission to the requested resource to manually manage the cookies? Thanks in advance.

  • JAVA Regular Expression Errors

    - by Berkay
    I'm working on a simply password strength checker and i can not success applying regular expressions. In different resources different kinds of regular expressions are defined. i also find javascript regular expressions but had some problems to adapt. First, these are the regular expressions i need for JAVA: at least one lower case letter at least one upper case letter at least one number at least three numbers at least one special character at least two special characters both letters and numbers both upper and lower case letters, numbers, and special characters My goal is not being a regular expression expert i just want to use the parts i need.If you direct me good tutorials which discusses above for java, will be appreciated. Second, in this link some of them are mentioned but i'm getting problems to apply them. here does not catch the lower case letter (my pass: A5677a) if (passwd.matches("(?=.*[a-z])")) // [verified] at least one lower case letter {Score = Score+5;} Also here i'm getting error : illegal escape character. if (passwd.matches("(?=.*\d)")) // [verified] at least one number Finally, are these expressions all different in different kind of programming or script languages?

  • Java Classpath Issues with Webservices(CXF) and Jboss

    - by JohnC
    I am using CXF(which autogenerates my webservices in my pom.xml from my wsdl) with JBoss(eclipse ide), and I am having some trouble accessing the webservice from my web application. I found this resource: http://blog.progs.be/?p=92 but I am having a really hard time using WSDL_LOCATION = cl.getResource( "my/progam/pack/wsdl/myService.wsdl" ); to work properly in my code. I have my wsdls located in src/main/wsdl and have added the following line to the .classpath file: classpathentry kind="src" path="src/main/wsdl" I also created the folders my,program,pack,wsdl and dropped my wsdls into that location, so it is accessible. However, the classloader.getResource call always returns null no matter what. When I specify getResource( "/wsdl/myService.wsdl" ) it does not return null, but I believe it looks at the full file path and not what I need (considering part of the URL contains the path to the wsdl file all the way through the jboss server directory and includes the WEB-INF dir. Is my .classpath file set up incorrectly or am I missing something else? if the WSDL Location is not correct it always throws a ClassCast Exception like so: java.lang.ClassCastException: org.apache.cxf.jaxws.ServiceImpl at javax.xml.ws.Service.(Service.java:81)

  • Maven: compile aspectj project containing Java 1.6 source

    - by gmale
    What I want to do is fairly easy. Or so you would think. However, nothing is working properly. Requirement: Using maven, compile Java 1.6 project using AspectJ compiler. Note: Our code cannot compile with javac. That is, it fails compilation if aspects are not woven in (because we have aspects that soften exceptions). Questions (based on failed attempts below): Either 1) How do you get maven to run the aspectj:compile goal directly, without ever running compile:compile? 2) How do you specify a custom compilerId that points to your own ajc compiler? Thanks for any and all suggestions. These are the things I've tried that have let to my problem/questions: Attempt 1 (fail): Specify aspectJ as the compiler for the maven-compiler-plugin: org.apache.maven.plugins maven-compiler-plugin 2.2 1.6 1.6 aspectj org.codehaus.plexus plexus-compiler-aspectj 1.8 This fails with the error: org.codehaus.plexus.compiler.CompilerException: The source version was not recognized: 1.6 No matter what version of the plexus compiler I use (1.8, 1.6, 1.3, etc), this doesn't work. I actually read through the source code and found that this compiler does not like source code above Java 1.5. Attempt 2 (fail): Use the aspectJ-maven-plugin attached to the compile and test-compile goals: org.codehaus.mojo aspectj-maven-plugin 1.3 1.6 1.6 compile test-compile This fails when running either: mvn clean test-compile mvn clean compile because it attempts to execute compile:compile before running aspectj:compile. As noted above, our code doesn't compile with javac--the aspects are required. So mvn would need to skip the compile:compile goal altogether and run only aspectj:compile. Attempt 3 (works but unnacceptable): Use the same configuration above but instead run: mvn clean aspectj:compile This works, in that it builds successfully but it's unacceptable in that we need to be able to run the compile goal and the test-compile goal directly (m2eclipse auto-build depends on those goals). Moreover, running it this way would require that we spell out every goal we want along the way (for instance, we need resources distributed and tests to be run and test resources deployed, etc)

I would like my program to recall the saved username and password, pass that to Facebook for authentication, and then allow the app to post simple text (maybe a link too) to the user's wall. That said, I've read everything on the developer pages at Facebook (the api looks completely foreign to me... I've never don't any type of web app development before... just desktop apps), and experimented with the Java libraries here: http://wiki.developers.facebook.com/index.php/User:Java but to be honest, I don't understand any of the various implementations. Some claim to be simple to use, but apparently they are all way above my head. I've even tried messing with the official Facebook Android SDK, but that uses a webview interface, and I can't pass in the username and password for easy authentication. Plus, I'm still clueless as to how to post to the wall even after correct authentication. Please help. Thanks. Oh, btw I already have a Facebook API key and Application ID.

  • Java exception handling in non sequential tasks (pattern/good practice)

    - by Hernán Eche
    There are some task that should't be done in parallel, (for example opening a file, reading, writing, and closing, there is an order on that...) But... Some task are more like a shoping list, I mean they could have a desirable order but it's not a must..example in communication or loading independient drivers etc.. For that kind of tasks, I would like to know a java best practice or pattern for manage exceptions.. The java simple way is: getUFO { try { loadSoundDriver(); loadUsbDriver(); loadAlienDetectorDriver(); loadKeyboardDriver(); } catch (loadSoundDriverFailed) { doSomethingA; } catch (loadUsbDriverFailed) { doSomethingB; } catch (loadAlienDetectorDriverFailed) { doSomethingC; } catch (loadKeyboardDriverFailed) { doSomethingD; } } But what about having an exception in one of the actions but wanting to try with the next ones?? I've thought this approach, but don't seem to be a good use for exceptions I don't know if it works, doesn't matter, it's really awful!! getUFO { Exception ex=null; try { try{ loadSoundDriver(); }catch (Exception e) { ex=e; } try{ loadUsbDriver(); }catch (Exception e) { ex=e; } try{ loadAlienDetectorDriver(); }catch (Exception e) { ex=e; } try{ loadKeyboardDriver() }catch (Exception e) { ex=e; } close the file; if(ex!=null) { throw ex; } } catch (loadSoundDriverFailed) { doSomethingA; } catch (loadUsbDriverFailed) { doSomethingB; } catch (loadAlienDetectorDriverFailed) { doSomethingC; } catch (loadKeyboardDriverFailed) { doSomethingD; } } seems not complicated to find a better practice for doing that.. I still didn't thanks for any advice

  • Java Memory Model: reordering and concurrent locks

    - by Steffen Heil
    Hi The java meomry model mandates that synchronize blocks that synchronize on the same monitor enforce a before-after-realtion on the variables modified within those blocks. Example: // in thread A synchronized( lock ) { x = true; } // in thread B synchronized( lock ) { System.out.println( x ); } In this case it is garanteed that thread B will see x==true as long as thread A already passed that synchronized-block. Now I am in the process to rewrite lots of code to use the more flexible (and said to be faster) locks in java.util.concurrent, especially the ReentrantReadWriteLock. So the example looks like this: // in thread A synchronized( lock ) { lock.writeLock().lock(); x = true; lock.writeLock().unlock(); } // in thread B synchronized( lock ) { lock.readLock().lock(); System.out.println( x ); lock.readLock().unlock(); } However, I have not seen any hints within the memory model specification that such locks also imply the nessessary ordering. Looking into the implementation it seems to rely on the access to volatile variables inside AbstractQueuedSynchronizer (for the sun implementation at least). However this is not part of any specification and moreover access to non-volatile variables is not really condsidered covered by the memory barrier given by these variables, is it? So, here are my questions: Is it safe to assume the same ordering as with the "old" synchronized blocks? Is this documented somewhere? Is accessing any volatile variable a memory barrier for any other variable? Regards, Steffen

  • Language Tricks to Shorten My Java Code?

    - by yar
    I am currently rediscovering Java (working with Ruby a lot recently), and I love the compilation-time checking of everything. It makes refactoring so easy. However, I miss playing fast-and-loose with types to do an each loop. This is my worst code. Is this as short as it can be? I have a collection called looperTracks, which has instances that implement Looper. I don't want to modify that collection, but I want to iterate through its members PLUS the this (which also implements Looper). List<Looper> allLoopers = new ArrayList<Looper>(looperTracks.length + 1); for (LooperTrack track : looperTracks) { allLoopers.add(track); } allLoopers.add(this); for (Looper looper : allLoopers) { // Finally! I have a looper I'm particularly concerned about any features that are new to Java from 1.5 on that I may have missed. For this question I am not asking about JRuby nor Groovy, though I know that they would work for this. Edit: Sorry (too much Ruby!)... looperTracks is of type LooperTrack[] and LooperTrack implements Looper.

  • JTable Delete All Rows Exception

    Hi, I'm trying to delete all entrys from my abstractTableModel. As long as I don't delete the last remaining row, everything works fine, but as soon as I delete this one, I get an ArrayOutOfBoundsException.

  • Using complex data types from Java in Axis webservice

    - by Manuel Ferreria
    I am currently developing a Java app which handles a SOAP webservice. The problem lies after I parse the WSDL [the Parser object from Apache Axis does it for me], and I create the call. When I try to invoke it, I have to pass a Object[] to assign the parameters [taken from the Action of the WSDL]. A normal action is easy, but when I have custom datatypes, I can't get it to fill it out for me. I try to pass Object[]{ new Object { }}, but it assigns the first field instead. I can't pass it already processed, because it changes the '< ' to '--lt --gt', and the server doesn't recognize it'. This is a fragment of the WSDL. <s:element name="FERecuperaQTYRequest"> <s:complexType> <s:sequence> <s:element minOccurs="0" maxOccurs="1" name="argAuth" type="tns:FEAuthRequest" /> </s:sequence> </s:complexType> </s:element> <s:complexType name="FEAuthRequest"> <s:sequence> <s:element minOccurs="0" maxOccurs="1" name="Token" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="Sign" type="s:string" /> <s:element minOccurs="1" maxOccurs="1" name="cuit" type="s:long" /> </s:sequence> </s:complexType> And this is the troublesome Java Fragment QTY = (String) call.invoke ( new Object[]{ new Object[]{ tokenConexion.getToken (), tokenConexion.getSign (), tokenConexion.getCUIT () } });

  • Oracle rownum in db2 - Java data archiving

    - by HonorGod
    I have a data archiving process in java that moves data between db2 and sybase. FYI - This is not done through any import/export process because there are several conditions on each table that are available on run-time and so this process is developed in java. Right now I have single DatabaseReader and DatabaseWriter defined for each source and destination combination so that data is moved in multiple threads. I guess I wanted to expand this further where I can have Multiple DatabaseReaders and Multiple DatabaseWriters defined for each source and destination combination. So, for example if the source data is about 100 rows and I defined 10 readers and 10 writer, each reader will read 10 rows and give them to the writer. I hope process will give me extreme performance depending on the resources available on the server [CPU, Memory etc]. But I guess the problem is these source tables do not have primary keys and it is extremely difficult to grab rows in multiple sets. Oracle provides rownum concept and i guess the life is much simpler there....but how about db2? How can I achieve this behavior with db2? Is there a way to say fetch first 10 records and then fetch next 10 records and so on? Any suggestions / ideas ? Db2 Version - DB2 v8.1.0.144 Fix Pack Num - 16 Linux

  • java TrayIcon using image with transparent background

    - by Jack
    I am using the following code to set a tray icon in Windows and Linux. It works wonderful in Windows and works okay in Linux. In Linux (Ubuntu) I have my panel set to be (somewhat) transparent and when I add a GIF (with a transparent background) the background of the icon shows up all grey and ugly (see image, green diamond "!")....Any ideas on how to make the GIF image I am adding "keep" its transparent background? and the image I am using, if you'd like to test: import java.awt.*; import java.awt.event.*; public class TrayFun { static class ShowMessageListener implements ActionListener { TrayIcon trayIcon; String title; String message; TrayIcon.MessageType messageType; ShowMessageListener( TrayIcon trayIcon, String title, String message, TrayIcon.MessageType messageType) { this.trayIcon = trayIcon; this.title = title; this.message = message; this.messageType = messageType; } public void actionPerformed(ActionEvent e) { trayIcon.displayMessage(title, message, messageType); } } public static void main(String args[]) { Runnable runner = new Runnable() { public void run() { if (SystemTray.isSupported()) { final SystemTray tray = SystemTray.getSystemTray(); Image image = Toolkit.getDefaultToolkit().getImage("green_info.png"); PopupMenu popup = new PopupMenu(); final TrayIcon trayIcon = new TrayIcon(image, "The Tip Text", popup); trayIcon.setImageAutoSize(true); MenuItem item = new MenuItem("Close"); item.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { tray.remove(trayIcon); } }); popup.add(item); try { tray.add(trayIcon); } catch (AWTException e) { System.err.println("Can't add to tray"); } } else { System.err.println("Tray unavailable"); } } }; EventQueue.invokeLater(runner); } }

  • Problem with AssetManager while loading a Model type

Please, help! Sorry for my bad English and my amateurish doubts.

  • sample java code for approximate string matching or boyer-moore extended for approximate string matc

    - by Dolphin
    Hi I need to find 1.mismatch(incorrectly played notes), 2.insertion(additional played), & 3.deletion (missed notes), in a music piece (e.g. note pitches [string values] stored in a table) against a reference music piece. This is either possible through exact string matching algorithms or dynamic programming/ approximate string matching algos. However I realised that approximate string matching is more appropriate for my problem due to identifying mismatch, insertion, deletion of notes. Or an extended version of Boyer-moore to support approx. string matching. Is there any link for sample java code I can try out approximate string matching? I find complex explanations and equations - but I hope I could do well with some sample code and simple explanations. Or can I find any sample java code on boyer-moore extended for approx. string matching? I understand the boyer-moore concept, but having troubles with adjusting it to support approx. string matching (i.e. to support mismatch, insertion, deletion). Also what is the most efficient approx. string matching algorithm (like boyer-moore in exact string matching algo)? Greatly appreciate any insight/ suggestions. Many thanks in advance

  • Java OutOfMemoryError due to Linux RAM disk cache not freed

    - by Markus Jevring
    The process will run fine all day, then, bam, without warning, it will throw this error. Sometimes seemingly in the middle of doing nothing. It will happen at seemingly random times during the day. I checked to see if anything else was running on the machine, like scheduled backups or something, but found nothing. The machine has enough physical memory (2GB, with about 1GB free for a 3-500MB load), and has sufficient -Xmx specified. According to our sysadmin, the problem is that the RAM that the kernel uses as a disk cache (apparently all but 8MB) is not freed when the JVM needs to allocate memory, so the JVM process throws an OutOfMemoryError. This could be because Java asks the kernel if enough memory is available before allocating and finds that it is insufficient, resulting in a crash. I would like to think, however, that Java simply tries to allocate the memory via the kernel, and when the kernel gets such a request, it makes room for the application by throwing our some of the disk cache. Has anyone else run in to the issue, and if so, what was the error, and how did you solve it? We are currently using jdk1.6.0_20 on SLES 10 SP2 Linux 2.6.16.60-0.42.9-smp in VMWare ESX.

  • Selecting a Java framework for large application w/ only ONE user

    - by Bijan
    I am building a large application that will be hosted on an AWS server. I'm trying to select a web framework for assisting me with code organization, template design, and generally presentation aspects. Here are some points of consideration: Require security/login/user authentication. I may add the ability in the future to allow more than just an administrator to access the web app, but it is not a public facing website. AJAX support would be helpful. There are a couple widgets that I don't want to recreate. One is a tree object, where the user can expand/contract items in the list, can create new branches, add/edit objects. This would be better off in some dynamic view rather than all done in ugly html. Generally, this is just to provide the application with a face for control, management, and monitoring. Having an easier time adding buttons, CSS, AJAX widgets are great additions though, but not the primary purpose. I'm considering: Wicket Spring Seam GWT Stripe and the list goes on, as I'm sure you all know. I originally planned on using GWT, but then started to feel that GWT didn't cover my primary needs. I could be wrong about this, but there seems to be a lot of support for GWT AND Wicket/Spring. All of this 'getting lost in java frameworks' got me thinking outside the java realm for a framework that would suit my needs that was a clear option, like: JRuby/Rails Jython/Django Groovy/Grails Guice (just throwing this in there... I don't clearly understand the main purposes of all these frameworks. It doesn't seem like DInjection is something I need for a single purpose application) Thanks as always. This community makes Googling for esoteric programming information an order of magnitude better.

  • Vote on Pros and Cons of Java HTML to XML cleaners

    - by George Bailey
    I am looking to allow HTML emails (and other HTML uploads) without letting in scripts and stuff. I plan to have a white list of safe tags and attributes as well as a whitelist of CSS tags and value regexes (to prevent automatic return receipt). I asked a question: Parse a badly formatted XML document (like an HTML file) I found there are many many ways to do this. Some systems have built in sanitizers (which I don't care so much about). This page is a very nice listing page but I get kinda lost http://java-source.net/open-source/html-parsers It is very important that the parsers never throw an exception. There should always be best guess results to the parse/clean. It is also very important that the result is valid XML that can be traversed in Java. I posted some product information and said Community Wiki. Please post any other product suggestions you like and say Community Wiki so they can be voted on. Also any comments or wiki edits on what part of a certain product is better and what is not would be greatly appreciated. (for example,, speed vs accuracy..) It seems that we will go with either jsoup (seems more active and up to date) or TagSoup (compatible with JDK4 and been around awhile). A +1 for any of these products would be if they could convert all style sheets into inline style on the elements.
