  • XStream noclassdeffound error

    - by Jimmy
    I am attempting to run Xstream in a netbeans proof of concept project. I have the following code. XStream xstream = new XStream(); FileOutputStream fis = new FileOutputStream("Test.xml"); xstream.toXML(company, fis); The program is crashing on the first line of code with the following error. Exception in thread "main" java.lang.NoClassDefFoundError: org/xmlpull/v1/XmlPullParserException at com.thoughtworks.xstream.XStream.<init>(XStream.java:336) at Parser.XParser.Parse(XParser.java:24) at rejaxbtest.REJAXBTest.main(REJAXBTest.java:39) Caused by: java.lang.ClassNotFoundException: org.xmlpull.v1.XmlPullParserException at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:423) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:356) ... 3 more Java Result: 1 I have seen one other thread with this problem, but the answer that was given was put the jar in the project lib directory, but netbeans has already correctly finished that task. Any other possible thing that would cause java not to recognize the Xstream class at runtime even though it is fine at compile time? Thanks Jimmy

  • Java to JavaScript (Encryptation related)

    - by balexandre
    Hi guys, I'm having dificulties to get the same string in Javascript and I'm thinking that I'm doing something wrong... Java code: import java.io.UnsupportedEncodingException; import java.security.MessageDigest; import java.security.NoSuchAlgorithmException; import java.util.Date; import java.util.GregorianCalendar; import sun.misc.BASE64Encoder; private static String getBase64Code(String input) throws UnsupportedEncodingException, NoSuchAlgorithmException { String base64 = ""; byte[] txt = input.getBytes("UTF8"); byte[] text = new byte[txt.length+3]; text[0] = (byte)239; text[1] = (byte)187; text[2] = (byte)191; for(int i=0; i<txt.length; i++) text[i+3] = txt[i]; MessageDigest md = MessageDigest.getInstance("MD5"); md.update(text); byte digest[] = md.digest(); BASE64Encoder encoder = new BASE64Encoder(); base64 = encoder.encode(digest); return base64; } I'm trying this using Paj's MD5 script as well Farhadi Base 64 Encode script but my tests fail completly :( my code: function CalculateCredentialsSecret(type, user, pwd) { var days = days_between(new Date(), new Date(2000, 1, 1)); var str = type.toUpperCase() + user.toUpperCase() + pwd.toUpperCase() + days; var md5 = any_md5('', str); var b64 = base64Encode(md5); return encodeURIComponent(b64); } Does anyone know how can I convert this Java method into a Javascript one? Thank you

  • NetBeans Java Hints: Quick & Dirty Guide

    - by Geertjan
    In NetBeans IDE 7.2, a new wizard will be found in the "Module Development" category in the New File dialog, for creating new Java Hints. Select a package in a NetBeans module project. Right click, choose New/Other.../Module Development/Java Hint: You'll then see this: Fill in: Class Name: the name of the class that should be generated. E.g. "Example". Hint Display Name: the display name of the hint itself (as will appear in Tools/Options). E.g. "Example Hint". Warning Message: the warning that should be produced by the hint. E.g. "Something wrong is going on". Hint Description: a longer description of the hint, will appear in Tools/Options and eventually some other places. E.g. "This is an example hint that warns about an example problem." Will also provide an Automatic Fix: whether the hint will provide some kind of transformation. E.g. "yes". Fix Display Name: the display name of such a fix/transformation. E.g. "Fix the problem". Click Finish. Should generate "Example.java", the hint itself: import com.sun.source.util.TreePath; import org.netbeans.api.java.source.CompilationInfo; import org.netbeans.spi.editor.hints.ErrorDescription; import org.netbeans.spi.editor.hints.Fix; import org.netbeans.spi.java.hints.ConstraintVariableType; import org.netbeans.spi.java.hints.ErrorDescriptionFactory; import org.netbeans.spi.java.hints.Hint; import org.netbeans.spi.java.hints.HintContext; import org.netbeans.spi.java.hints.JavaFix; import org.netbeans.spi.java.hints.TriggerPattern; import org.openide.util.NbBundle.Messages; @Hint(displayName = "DN_com.bla.Example", description = "DESC_com.bla.Example", category = "general") //NOI18N @Messages({"DN_com.bla.Example=Example Hint", "DESC_com.bla.Example=This is an example hint that warns about an example problem."}) public class Example { @TriggerPattern(value = "$str.equals(\"\")", //Specify a pattern as needed constraints = @ConstraintVariableType(variable = "$str", type = "java.lang.String")) @Messages("ERR_com.bla.Example=Something wrong is going on") public static ErrorDescription computeWarning(HintContext ctx) { Fix fix = new FixImpl(ctx.getInfo(), ctx.getPath()).toEditorFix(); return ErrorDescriptionFactory.forName(ctx, ctx.getPath(), Bundle.ERR_com.bla_Example(), fix); } private static final class FixImpl extends JavaFix { public FixImpl(CompilationInfo info, TreePath tp) { super(info, tp); } @Override @Messages("FIX_com.bla.Example=Fix the problem") protected String getText() { return Bundle.FIX_com_bla_Example(); } @Override protected void performRewrite(TransformationContext ctx) { //perform the required transformation } } } Should also generate "ExampleTest.java", a test for it. Unfortunately, the wizard infrastructure is not capable of handling changes related to test dependencies. So the ExampleTest.java has a todo list at its begining: /* TODO to make this test work:  - add test dependency on Java Hints Test API (and JUnit 4)  - to ensure that the newest Java language features supported by the IDE are available,   regardless of which JDK you build the module with:  -- for Ant-based modules, add "requires.nb.javac=true" into nbproject/project.properties  -- for Maven-based modules, use dependency:copy in validate phase to create   target/endorsed/org-netbeans-libs-javacapi-*.jar and add to endorseddirs   in maven-compiler-plugin configuration  */Warning: if this is a project for which tests never existed before, you may need to close&reopen the project, so that "Unit Test Libraries" node appears - a bug in apisupport projects, as far as I can tell.  Thanks to Jan Lahoda for the above rough guide.

  • JAVA-SQL- Data Migration - ResultSets comparing Failing JUnit test

    - by user1865053
    I CANNOT get this JUnit Test to pass for the life of me. Can somebody point out where this has gone wrong. I am doing a data migration(MSSQL SERVER 2005), but I have the sourceDBUrl and the targetDCUrl the same URL so to narrow it down to syntax errors. So that is what I have, a syntax error. I am comparing the results of a table for the query SELECT programmeapproval, resourceapproval FROM tr_timesheet WHERE timesheetid = ? and the test always fails, but passes for other junit tests I have developed. I created 3 diffemt resultSetsEqual methods and none work. Yet, some other JUnit tests I have developed have PASSED.

  • What should you do differently when designing websites for an embedded web server

    - by Roger Attrill
    When designing a website to be accessed from an embedded webserver such as KLone, what do you need to do differently compared to a 'standard' web server. I'm talking about considerations at the front end design stage, before the actual building and coding up. For example, typically in such situations, memory size is a premium, so I guess larger images are out, and maybe more attention should be focused on achieving a good look and feel using CSS/Javascript rather than bitmap images.

  • IBM Keynote: (hardware,software)–>{IBM.java.patterns}

    - by Janice J. Heiss
    On Sunday evening, September 30, 2012, Jason McGee, IBM Distinguished Engineer and Chief Architect Cloud Computing, along with John Duimovich IBM Distinguished Engineer and Java CTO, gave an information- and idea-rich keynote that left Java developers with much to ponder.Their focus was on the challenges to make Java more efficient and productive given the hardware and software environments of 2012. “One idea that is very interesting is the idea of multi-tenancy,” said McGee, “and how we can move up the spectrum. In traditional systems, we ran applications on dedicated middleware, operating systems and hardware. A lot of customers still run that way. Now people introduce hardware virtualization and share the hardware. That is good but there is a lot more we can do. We can share middleware and the application itself.” McGee challenged developers to better enable the Java language to function in these higher density models. He spoke about the need to describe patterns that help us grasp the full environment that an application needs, whether it’s a web or full enterprise application. Developers need to understand the resources that an application interacts with in a way that is simple and straightforward. The task is to then automate that deployment so that the complexity of infrastructure can be by-passed and developers can live in a simpler world where the cloud can automatically configure the needed environment. McGee argued that the key, something IBM has been working on, is to use a simpler pattern that allows a cloud-based architecture to embrace the entire infrastructure required for an application and make it highly available, scalable and able to recover from failure. The cloud-based architecture would automate the complexity of setting up and managing the infrastructure. IBM has been trying to realize this vision for customers so they can describe their Java application environment simply and allow the cloud to automate the deployment and management of applications. “The point,” explained McGee, “is to package the executable used to describe applications, to drop it into a shared system and let that system provide some intelligence about how to deploy and manage those applications.”John Duimovich on Improvements in JavaMcGee then brought onstage IBM’s Distinguished Engineer and CTO for Java, John Duimovich, who showed the audience ways to deploy Java applications more efficiently.Duimovich explained that, “When you run lots of copies of Java in the cloud or any hypervisor virtualized system, there are a lot of duplications of code and jar files. IBM has a facility called ‘shared classes’ where we put shared code, read only artefacts in a cache that is sharable across hypervisors.” By putting JIT code in ahead of time, he explained that the application server will use 20% less memory and operate 30% faster.  He described another example of how the JVM allows for the maximum amount of sharing that manages the tenants and file sockets and memory use through throttling and control. Duimovich touched on the “thin is in” model and IBM’s Liberty Profile and lightweight runtime for the cloud, which allows for greater efficiency in interacting with the cloud.Duimovich discussed the confusion Java developers experience when, for example, the hypervisor tells them that that they have 8 and then 4 and then 16 cores. “Because hypervisors are virtualized, they can change based on resource needs across the hypervisor layer. You may have 10 instances of an operation system and you may need to reallocate memory, " explained Duimovich.  He showed how to resize LPARs, reallocate CPUs and migrate applications as needed. He explained how application servers can resize thread pools and better use resources based on information from the hypervisors.Java Challenges in Hardware and SoftwareMcGee ended the keynote with a summary of upcoming hardware and software challenges for the Java platform. He noted that one reason developers love Java is it allows them to ignore differences in hardware. He stated that the most important things happening in hardware were in network and storage – in developments such as the speed of SSD, the exploitation of high-speed, low-latency networking, and recent developments such as storage-class memory, and non-volatile main memory. “So we are challenged to maintain the benefits of Java and the abstraction it provides from hardware while still exploiting the new innovations in hardware,” said McGee.McGee discussed transactional messaging applications where developers send messages transactionally persist a message to storage, something traditionally done by backing messages on spinning disks, something mostly outdated. “Now,” he pointed out, “we would use SSD and store it in Flash and get 70,000 messages a second. If we stored it using a PCI express-based flash memory device, it is still Flash but put on a PCI express bus on a card closer to the CPU. This way I get 300,000 messages a second and 25% improvement in latency.” McGee’s central point was that hardware has a huge impact on the performance and scalability of applications. New technologies are enabling developers to build classes of Java applications previously unheard of. “We need to be able to balance these things in Java – we need to maintain the abstraction but also be able to exploit the evolution of hardware technology,” said McGee. According to McGee, IBM's current focus is on systems wherein hardware and software are shipped together in what are called Expert Integrated Systems – systems that are pre-optimized, and pre-integrated together. McGee closed IBM’s engaging and thought-provoking keynote by pointing out that the use of Java in complex applications is increasingly being augmented by a host of other languages with strong communities around them – JavaScript, JRuby, Scala, Python and so forth. Java developers now must understand the strengths and weaknesses of such newcomers as applications increasingly involve a complex interconnection of languages.

  • Embedded Model Designing -- top down or bottom up?

    - by Jeff
    I am trying to learn RoR and develop a webapp. I have a few models I have thought of for this app, and they are fairly embedded. For example (please excuse my lack of RoR syntax): Model: textbook title:string type:string has_many: chapters Model: chapter content:text has_one: review_section Model: review_section title:string has_many: questions has_many: answers , through :questions Model: questions ... Model: answers ... My question is, with the example I gave, should I start at the top model (textbook) or the bottom most (answers)?

  • What are the options for simple Ajax calls for a Java webapp?

    - by Cedric Martin
    I've got a very simple need and I don't know what are the options available. If I simplify, users see webpage like this server by a Java webapp server: [-] red [x] green [-] blue [-] yellow The selected color is green And then I want the user to be able to select the yellow color and have the part of the page containing the relevant text change to: [-] red [-] green [-] blue [x] yellow The selected color is yellow Basically I want something a bit more user friendly than simply using HTTP GET all the time. There shall be a lot of options the user can select from and this shall affect an (HTML formatted) text displayed on the page. And I want the user to see his change as soon as possible, without having the page to fully reload and without being redirected to another page. There shall be a client/server round-trip (the information to display depending on the options selected ain't available on the client-side so I cannot do it all in JavaScript in the browser). I'd like to use Ajax requests but I don't know which way to go: jQuery GWT something else What are my options and what would be the pros and cons of the various approach? P.S: I'm very familiar with Java (SCP since the last century and basically being a Java programmer for the last 12 years or so) but not familiar at all with JavaScript (though I did hack a few Ajaxy-calls years ago, way before great libraries existed).

  • How handle nifty initialization in a Slick2D state based game?

    - by nathan
    I'm using Slick2D and Nifty GUI. I decided to use a state based approach for my game and since i want to use Nifty GUI, i use the classes NiftyStateBasedGame for the main and NiftyOverlayBasicGameState for the states. As the description say, i'm suppose to initialize the GUI in the method initGameAndGUI on my states, no problem: @Override protected void initGameAndGUI(GameContainer gc, StateBasedGame sbg) throws SlickException { initNifty(gc, sbg) } It works great when i have only one state but if i'm doing a call to initNifty several times from different states, it will raise the following exception: org.bushe.swing.event.EventServiceExistsException: An event service by the name NiftyEventBusalready exists. Perhaps multiple threads tried to create a service about the same time? at org.bushe.swing.event.EventServiceLocator.setEventService(EventServiceLocator.java:123) at de.lessvoid.nifty.Nifty.initalizeEventBus(Nifty.java:221) at de.lessvoid.nifty.Nifty.initialize(Nifty.java:201) at de.lessvoid.nifty.Nifty.<init>(Nifty.java:142) at de.lessvoid.nifty.slick2d.NiftyCarrier.initNifty(NiftyCarrier.java:94) at de.lessvoid.nifty.slick2d.NiftyOverlayBasicGameState.initNifty(NiftyOverlayBasicGameState.java:332) at de.lessvoid.nifty.slick2d.NiftyOverlayBasicGameState.initNifty(NiftyOverlayBasicGameState.java:299) at de.lessvoid.nifty.slick2d.NiftyOverlayBasicGameState.initNifty(NiftyOverlayBasicGameState.java:280) at de.lessvoid.nifty.slick2d.NiftyOverlayBasicGameState.initNifty(NiftyOverlayBasicGameState.java:264) The initializeEventBus that raise the exception is called from the Nifty constructor and a new Nifty object is created within the initNifty method: public void initNifty( final SlickRenderDevice renderDevice, final SlickSoundDevice soundDevice, final SlickInputSystem inputSystem, final TimeProvider timeProvider) { if (isInitialized()) { throw new IllegalStateException("The Nifty-GUI was already initialized. Its illegal to do so twice."); } final InputSystem activeInputSystem; if (relayInputSystem == null) { activeInputSystem = inputSystem; } else { activeInputSystem = relayInputSystem; relayInputSystem.setTargetInputSystem(inputSystem); } nifty = new Nifty(renderDevice, soundDevice, activeInputSystem, timeProvider); } Is this a bug in the nifty for slick2d implementation or am i missing something? How am i supposed to handle nifty initialization over multiple states?

  • Pythonic Java. Yes, or no?

    - by OscarRyz
    Python use of indentation for code scope was initially very polemic and now is considered one of the best language features, because it helps ( almost by forcing us ) to have a consistent style. Well, I saw this post http://bit.ly/hmvTe9 where someone posted Java code with ; y {} aligned to the right margin to look more pythonic. It was very shocking at first ( as a matter of fact, if I ever see Java code like that in one of my projects I would be scared! ) However, there is something interesting here. Do we need all those braces and semicolons? How would the code would look like without them? class Person int age void greet( String a ) if( a == "" ) out.println("Hello stranger") else out.printf("Hello %s%n", a ) int age() return this.age class Main void main() new Person().greet("") Looks good to me, but in such small piece of code is hard to appreciate it, and since I don't Python too much, I can't tell by looking at existing libraries if it would be cleaner or not. So I took the first file of a library named: jAlarms I found and this is the result: ( WARNING : the following image may be disturbing for some people ) http://pxe.pastebin.com/eU1R4xsh Obviously it doesn't compile. This would be a compiling version using right aligned {} and ; http://pxe.pastebin.com/2uijtbYM Question What would happen if we could code like this? Would it make things clearer? Would it make it harder? I see braces, and semicolons as help to the parser and we, as humans have get used to them, but do we really need them? I guess is hard to tell specially since many mainstream languages do use braces, C, C++, Java, C# JavaScript Assuming the compiler wouldn't have problems without them, would you use them? Please comment.

I tried atleast a dozen different tmx files from numerous examples to see if it was the actual file that was corrupted. Everytime I get this error: Exception in thread "main" java.lang.RuntimeException: Resource not found: data/maps/desert.tmx at org.newdawn.slick.util.ResourceLoader.getResourceAsStream(ResourceLoader.java:69) at org.newdawn.slick.tiled.TiledMap.<init>(TiledMap.java:101) at game.Game.init(Game.java:17) at game.Tunneler.initStatesList(Tunneler.java:37) at org.newdawn.slick.state.StateBasedGame.init(StateBasedGame.java:164) at org.newdawn.slick.AppGameContainer.setup(AppGameContainer.java:390) at org.newdawn.slick.AppGameContainer.start(AppGameContainer.java:314) at game.Tunneler.main(Tunneler.java:29) Here is my Game class: package game; import org.newdawn.slick.GameContainer; import org.newdawn.slick.Graphics; import org.newdawn.slick.SlickException; import org.newdawn.slick.state.BasicGameState; import org.newdawn.slick.state.StateBasedGame; import org.newdawn.slick.tiled.TiledMap; public class Game extends BasicGameState{ private int stateID = -1; private TiledMap map = null; public Game(int stateID){ this.stateID = stateID; } public void init(GameContainer container, StateBasedGame game) throws SlickException{ map = new TiledMap("data/maps/desert.tmx","maps");//ERROR } public void render(GameContainer container, StateBasedGame game, Graphics g) throws SlickException{ //map.render(0,0); } public void update(GameContainer container, StateBasedGame game, int delta) throws SlickException{ } public int getID(){return stateID;} } I've tried to see if anyone else has had similar problems but haven't turned up anything. I am able to load other files, so I don't believe it's a compiler issue. My menu class can load images and display them just fine. Also, the filepath is correct. Please let me know if you have any pointers that might help me sort this out.

  • J2EE or .Net Framework [closed]

    - by Kevino
    I want to learn JAVA or C#... tell me the strength and weakness of each platforms J2EE and .Net Framework today in 2012 and which is safer for the future jobs wise? I tend to prefer Java because here (Montreal, Toronto) there is like 6 Java jobs for each C# jobs and some experienced programmers advised me to go with Java because they say JVM languages are winning in the cloud and the rise of Android can't do anything except help Java in the long run. Is that true today with the release of windows 8 soon and ios devices? On the other side 1 of these programmers told me that corporation love Asp.Net Mvc3 for intranet and web dev and that tomcat/apache java jsp adoption is slowing down compared to Asp.net and ruby on rails & html5 etc. He told me too since I have a good background in system admins & networking C# would be better for me because I'll be able to do more things in the microsoft world with powershell automation and creating my own apps for all the networking stuffs (windows server, dns,dhcp, active directory, sharepoint etc). But what if windows 8 flop java and android aren't safer in the long run? because he told me mono was a joke compared to Java/android or native objective-c on ios devices. (I plan to do a full time study of 10hr's / 15hr's a day for the next 9 months of either Java or C# that's why I ask this)

  • Should we choose Java over C# or we should consider using Mono?

    - by A. Karimi
    We are a small team of independent developers with an average experience of 7 years in C#/.NET platform. We almost work on small to average web application projects that allows us to choose our favorite platform. I believe that our current platform (C#/.NET) allows us to be more productive than if we were working in Java but what makes me think about choosing Java over C# is the costs and the community (of the open source). Our projects allow us even work with various frameworks as well as various platforms. For example we can even use Nancy. So we are able to decrease the costs by using Mono which can be deployed on Linux servers. But I'm looking for a complete ecosystem (IDE/Platform/Production Environment) that decreases our costs and makes us feel completely supported by the community. As an example of issues I've experienced with MonoDevelop, I can refer to the poor support of the Razor syntax on MonoDevelop. As another example, We are using "VS 2012 Express for Web" as our IDE to decrease the costs but as you know it doesn't support plugins and I have serious problems with XML comments (I missed GhostDoc). We strongly believe in strongly-typed programming languages so please don't offer the other languages and platforms such as Ruby, PHP, etc. Now I want to choose between: Keep going on C#, buy some products and be hopeful about openness of .NET ecosystem and its open source community. Changing the platform and start using the Java open source ecosystem

  • How do I initialize a Scala map with more than 4 initial elements in Java?

    - by GlenPeterson
    For 4 or fewer elements, something like this works (or at least compiles): import scala.collection.immutable.Map; Map<String,String> HAI_MAP = new Map4<>("Hello", "World", "Happy", "Birthday", "Merry", "XMas", "Bye", "For Now"); For a 5th element I could do this: Map<String,String> b = HAI_MAP.$plus(new Tuple2<>("Later", "Aligator")); But I want to know how to initialize an immutable map with 5 or more elements and I'm flailing in Type-hell. Partial Solution I thought I'd figure this out quickly by compiling what I wanted in Scala, then decompiling the resultant class files. Here's the scala: object JavaMapTest { def main(args: Array[String]) = { val HAI_MAP = Map(("Hello", "World"), ("Happy", "Birthday"), ("Merry", "XMas"), ("Bye", "For Now"), ("Later", "Aligator")) println("My map is: " + HAI_MAP) } } But the decompiler gave me something that has two periods in a row and thus won't compile (I don't think this is valid Java): scala.collection.immutable.Map HAI_MAP = (scala.collection.immutable.Map) scala.Predef..MODULE$.Map().apply(scala.Predef..MODULE$.wrapRefArray( scala.Predef.wrapRefArray( (Object[])new Tuple2[] { new Tuple2("Hello", "World"), new Tuple2("Happy", "Birthday"), new Tuple2("Merry", "XMas"), new Tuple2("Bye", "For Now"), new Tuple2("Later", "Aligator") })); I'm really baffled by the two periods in this: scala.Predef..MODULE$ I asked about it on #java on Freenode and they said the .. looked like a decompiler bug. It doesn't seem to want to compile, so I think they are probably right. I'm running into it when I try to browse interfaces in IntelliJ and am just generally lost. Based on my experimentation, the following is valid: Tuple2[] x = new Tuple2[] { new Tuple2<String,String>("Hello", "World"), new Tuple2<String,String>("Happy", "Birthday"), new Tuple2<String,String>("Merry", "XMas"), new Tuple2<String,String>("Bye", "For Now"), new Tuple2<String,String>("Later", "Aligator") }; scala.collection.mutable.WrappedArray<Tuple2> y = scala.Predef.wrapRefArray(x); There is even a WrappedArray.toMap() method but the types of the signature are complicated and I'm running into the double-period problem there too when I try to research the interfaces from Java.
