  • Determining default character set of platform in Java

    - by Anand
    I am programming in Java I have the code as: byte[] b = test.getBytes(); In the api it is specified that if we do not specify character encoding it takes the default platform character encoding. What is meant by "default platform character encoding" ? Does it mean the Java encoding or the OS encoding ? If it means OS encoding the how can i check the default character encoding of Windows and Linux ? Is there anyway we can get the default character encoding using command line ?

  • ColumnChart google visualization column color change

    - by drozzy
    Does anyone know if I can hack google's visualization ColumnChart api chart somehow, to make a single column stand out with a different color, like so: I know you can do it with ImageChart, so I don't need that (it fires no events and has no x/y labels). Can I traverse the result with javascript somehow and change the CSS style, if it is truly rendered in SVG?

  • Implementation of ECC in Java

    - by Rookie_22
    While trying to encrypt a given input using Elliptic Curve Cryptography in Java I'm using the following algorithms for generating the cipher and the key: KeyPairGenerator g = KeyPairGenerator.getInstance("ECDSA"); Cipher cipher = Cipher.getInstance("ECIES"); Now as expected, the cipher isn't accepting the keys generated by the ECDSA algorithm. I get the error as - must be passed IE key. I searched for the ciphers being supported by these 2 methods here: http://java.sun.com/javase/6/docs/technotes/guides/security/StandardNames.html#Cipher Unfortunately no else algo is supported for ECC. Has anyone used ECC generated keys to encrypt/decrypt an input? Which algo should I use for both so that they don't clash with each other?

    - by raqz
    i have this app that i developed and it works great on the simulator with no errors what so ever. but the moment i try to run the same on the phone for testing, the app crashes stating filenotfoundexception. it says the file /res/drawable/divider_horizontal.9.png is missing. but actually speaking, i have never referenced that file through my code. i believe its a system/os file that is unavailable. i have a custom list view, i guess its the divider there... could somebody please suggest what is wrong here. i believe this is a similar issue discussed here..but i am unable to make

  • Automatic type conversion in Java?

    - by davr
    Is there a way to do automatic implicit type conversion in Java? For example, say I have two types, 'FooSet' and 'BarSet' which both are representations of a Set. It is easy to convert between the types, such that I have written two utility methods: /** Given a BarSet, returns a FooSet */ public FooSet barTOfoo(BarSet input) { /* ... */ } /** Given a FooSet, returns a BarSet */ public BarSet fooTObar(FooSet input) { /* ... */ } Now say there's a method like this that I want to call: public void doSomething(FooSet data) { /* .. */ } But all I have is a BarSet myBarSet...it means extra typing, like: doSomething(barTOfoo(myBarSet)); Is there a way to tell the compiler that certain types can automatically be cast to other types? I know this is possible in C++ with overloading, but I can't find a way in Java. I want to just be able to type: doSomething(myBarSet); And the compiler knows to automatically call barTOfoo()

  • Java char literal to C# char literal

    - by Kristoffersen
    Hi. I am maintaining some Java code that I am currently converting to C#. The Java code is doing this: sendString(somedata + '\000'); And in C# I am trying to do the same: sendString(somedata + '\000'); But on the '\000' VS2010 tells me that "Too many characters in character literal". How can I use '\000' in C#? I have tried to find out what the character is, but it seems to be " " or some kind of newline-character. Do you know anything about the issue? Thanks!

  • java.net.SocketTimeoutException: Read timed out

    - by Rafael Soto
    Hi Folks, I have an application with client server architecture. The client use Java Web Start with Java Swing / AWT and the sert uses HTTP server / Servlet with Tomcat. The communication is made from the serialization of objects, create a ObjectOutput serializes a byte array and send to the server respectively called the ObjectInputStream and deserializes. The application follows communicating correctly to a certain time of concurrency where starting to show error "SocketException read timeout". The erro happens when the server invoke the method ObjectInputStream.getObject() in my servlet doPost method. The tomcat will come slow and the errors start to decrease server response time until the crash time where i must restart the server and after everything works. Someone went through this problem ?

  • Building an XML editor in java and RichFaces

    - by Mark Lewis
    Hello I'm building an XML editor using the above technologies. In essence, I want to read in a whole XML file to a java object, and refer using this object to each element in the XML node tree (grouped into entries) to display the content locked, have separate padlocks for the user to click to 'unlock' an entry allow overwriting of the data, and to submit this entry. 'Add entry', 'Duplicate entry', 'Delete entry' are also functions I'd like to add. I already use dom4j and XPath to access areas of the XML file so some of the work in theory is already done. Given the above, I was going to use these two together with inplaceInputs to allow the user to edit the XML and JSF validators to check the data coming in. Is this the best way to approach this problem, or is there a more straightforward route than XPathing a whole record? I started looking at jaxb but I'm new at java and jsf but I've got the feeling I won't be by the end.. Thanks

  • When should one use the following: Amazon EC2, Google App Engine, Microsoft Azure and Salesforce.com

    - by vicky21
    I am asking this in very general sense. Both from cloud provider and cloud consumer's perspective. Also the question is not for any specific kind of application (in fact the intention is to know which type of applications/domains can fit into which of the cloud slab -SaaS PaaS IaaS). My understanding so far is: IaaS: Raw Hardware (Processors, Networks, Storage). PaaS: OS, System Softwares, Development Framework, Virtual Machines. SaaS: Software Applications. It would be great if Stackoverflower's can share their understanding and experiences of cloud computing concept. EDIT: Ok, I will put it in more specific way - Amazon EC2: You don't have control over hardware layer. But you can take your choice of OS image, Dev Framework (.NET, J2EE, LAMP) and Application and put it on EC2 hardware. Can you deploy an applications built with Google App Engine or Azure on EC2? Google App Engine: You don't have control over hardware and OS and you get a specific Dev Framework to build your application. Can you take any existing Java or Python application and port it to GAE? Or vice versa, can applications that were built on GAE be taken out of GAE and ported to any Application Server like Websphere or Weblogic? Azure: You don't have control over hardware and OS and you get a specific Dev Framework to build your application. Can you take any existing .NET application and port it to Azure? Or vice versa, can applications that were built on Azure be taken out of Azure and ported to any Application Server like Biztalk?

  • java generics covariance

    - by soocracy42
    I am having trouble understanding the following article: http://www.ibm.com/developerworks/java/library/j-jtp01255.html Under, Generics are not covariant the author states, Because ln is a List, adding a Float to it seems perfectly legal. But if ln were aliased with li, then it would break the type-safety promise implicit in the definition of li -- that it is a list of integers, which is why generic types cannot be covariant. I can't understand the part where it says "if ln were aliased with li". What does the author means by alias?(reference?). The code snippet above the quoted line seems to illustrate WHAT is illegal in java and not WHY. It would be very helpful to me if somebody could explain with an example. Thanks in advance.

  • How to get the stacktrace in a mobile device?

    - by Daniel Moura
    I'm getting a NullPointerException in a Nokia S40. I want to know what is causing this exception. The device shows: NullPointerException java/lang/NullPointerException This error only occurs in the device, running in the emulator the application works fine. I use microlog to debug my application. But the application works fine if the log is enabled. Is there a way to get the stack trace when I get this NullPointerException? I don't need all details like the line number just which method cause this exception. UPDATE: I installed the same application in another Nokia S40 and the same error didn't occur. Nokia 2660 - error Nokia 6131 - no error UPDATE 2: Somehow I find what was causing the NullPointerException. import javax.microedition.lcdui.Canvas; import javax.microedition.lcdui.Graphics; public class OuterClass extends Canvas { private Config config; public OuterClass() { this.config = new Config(); } public void paint(Graphics graphics) { HelperClass helper = new HelperClass(this.config); helper.doStuff(); } public void dispose() { this.config = null; } public class Config implements IConfig { public int getSomething() { // ... } } } public class HelperClass { private IConfig config; public HelperClass(IConfig) { this.config = config; } public doStuff() { config.getSomething(); // Here is thrown NullPointerException } } In some situations a thread is started and call the OuterClass.dispose() before the helper.doStuff() causing the NPE. I think when I enabled the log it made the thread slower and helper.doStuff() was called when I expected it to be called.

  • Simulating Google Appengine's Task Queue with Gearman

    - by sotangochips
    One of the characteristics I love most about Google's Task Queue is its simplicity. More specifically, I love that it takes a URL and some parameters and then posts to that URL when the task queue is ready to execute the task. This structure means that the tasks are always executing the most current version of the code. Conversely, my gearman workers all run code within my django project -- so when I push a new version live, I have to kill off the old worker and run a new one so that it uses the current version of the code. My goal is to have the task queue be independent from the code base so that I can push a new live version without restarting any workers. So, I got to thinking: why not make tasks executable by url just like the google app engine task queue? The process would work like this: User request comes in and triggers a few tasks that shouldn't be blocking. Each task has a unique URL, so I enqueue a gearman task to POST to the specified URL. The gearman server finds a worker, passes the url and post data to a worker The worker simply posts to the url with the data, thus executing the task. Assume the following: Each request from a gearman worker is signed somehow so that we know it's coming from a gearman server and not a malicious request. Tasks are limited to run in less than 10 seconds (There would be no long tasks that could timeout) What are the potential pitfalls of such an approach? Here's one that worries me: The server can potentially get hammered with many requests all at once that are triggered by a previous request. So one user request might entail 10 concurrent http requests. I suppose I could have a single worker with a sleep before every request to rate-limit. Any thoughts?

  • LXML E builder for java?

    - by directedition
    There is one thing I really love about LXML, and that the E builder. I love that I can throw XML together like this: message = E.Person( E.Name( E.First("jack") E.Last("Ripper") ) E.PhoneNumber("555-555-5555") ) To make: <Person> <Name> <First>Jack</First> <Last>Ripper</Last> </Name> <PhoneNumber>555-555-5555</PhoneNumber> </Person> As opposed to the painstaking way DOM works. I am going to be moving a bunch of my software to Java soon and it is very very heavy on its usage of E. Does Java have anything near equivalent to that usage?
