  • Navigate to the Same Page After Action in JSF 2

    - by shipmaster
    I have a component done in JSF 1.x, this component has a command button as follows <h:commandButton ... action="#{templateController.next}" /> Where templateController was passed as an EL binding and can be any object that implements a certain interface. The generic implementation of next() was just executing code and then returning an empty string causing the same page to refresh: public String next() { ..... return ""; } Now I am trying to port that component to JSF 2, my problem is that an empty string doesn't cause the same page to refresh anymore, instead, the framework tries to redirect to a page called ".jsf" i.e it just appends .jsf to whatever the outcome is. My question is how to return an outcome that causes the current page to refresh. My component is generic and I don't know before hand the name of the page it is going to be used on. Thanks

  • GWT: Best practice for unit testing / mocking JSNI methods?

    - by Epaga
    I have a class which uses JSNI to retrieve JSON data stored in the host page: protected native JsArray<JsonModel> getModels() /*-{ return $wnd.jsonData; }-*/; This method is called, and the data is then translated and process in a different method. How should I unit test this class, since I'm not able to instantiate (or seemingly mock?) JsArray? What is the best way to unit test JSNI methods at all?

  • How to CompareTo two Object without known about their real type

    - by Kamil
    I have to implement a one linked list but it should put object in appropriate position. Everything was OK when I use it in conjunction with specific class, but when I tried make it universal and argument of method insert was Object some problem appeared. When I want to input Object in right position I should use CompareTo method, but there isn't method in Object class! The problem is how to compare two object elements without known about their real types. Maybe I should use generic class type? But what about CompareTo? Or maybe combine with Element class and place CompareTo there? I suppose it is feasible. :) public void insert(Object o) { Element el = new Element(o); // initializing and setting iterators while(!it.isDone() && ((it.current().getValue())).CompareTo(o)<0) // it.current() returns Element of List { //move interators } //... }

  • How to handle runtime exception on playing audio files?

    - by Maxood
    I have a button that plays an audio file on its click listener. If the button is clicked again and again while the audio file is being played then the app crashes. What's the solution? Here is some code for reference: private OnClickListener btnMercyListener = new OnClickListener() { public void onClick(View v) { // Toast.makeText(getBaseContext(), // "Mercy audio file is being played", // Toast.LENGTH_LONG).show(); if (status==true) { mp.stop(); mp.release(); status = false; } else { mp = MediaPlayer.create(iMEvil.this,R.raw.mercy); //mp.start(); try{ mp.start(); status= true; //mp.release(); }catch(NullPointerException e) { Log.v("MP error",e.toString()); } } mp.setOnCompletionListener(new OnCompletionListener(){ // @Override public void onCompletion(MediaPlayer arg0) { mp.release(); status = false; } } ); } };

    - by Llistes Sugra
    I have a 300 KB xml file with 70 elements in it. I need to be efficient upon removing one of the root's elements. What is the best approach? Should I detach the element in memory, save it and overwrite it by moving it? Is there a better option? I like org.jdom but any improvement is welcome

  • How to add DOCTYPE and xml processing instructions when marshalling with JAXB?

    - by Juha Syrjälä
    I am marshalling (serializing) JAXB beans to output stream. How can I add DOCTYPE declaration and xml processing instructions to ouput? I am doing currently marshalling like this: JAXBContext jaxbContext = JAXBContext.newInstance("com.example.package"); Marshaller marshaller = jaxbContext.createMarshaller(); marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE); SchemaFactory schemaFactory = SchemaFactory.newInstance("http://www.w3.org/2001/XMLSchema"); Schema schema = schemaFactory.newSchema(schemaSource); marshaller.setSchema(schema); marshaller.marshal(object, output); I'd like have output that looks something like this: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE Something SYSTEM "some.dtd"> <?xml-stylesheet type="text/xsl" href="some.xsl"?> JAXB bean are generated code so I don't want to change them. There are some undocumented tricks to add the xml processing instructions and doctype. But what is the preferred or right way to do this?

  • jqGrid problem, expecting jQuery.jgrid but $.jgrid exists instead

    - by Sam
    I'm using jqGrid for a JIRA plugin and have included the jquery and jqgrid libraries as web resources. I've set up a column in jqGrid as required and when I try to submit the form with the respective column empty I get an error in firebug: jQuery.jgrid is undefined jQuery.jgrid is null but $.jgrid has the correct data. Does anyone know how I can set up jqgrid so that it points to the $.jgrid without having to change all the source code? or any other way round this? Thanks

  • adding only odd numbers

    - by Jessica M.
    So the question I'm trying to solve the user is supposed to enter any positive number. Then I'm trying to write a program that adds only the odd numbers up to the number the user enters and displays the total. So for example if the user enters 4 my program should add four odd numbers. 1 + 3 + 5 + 7 = 16. The only tools I have available are for statement, if, if/else if,while loop and println. I can only figure out how to print out the odd numbers. I know I want to create a variable named total to store the value of adding up all the odd numbers but I don't know how that fits into the program. import acm.program.*; public class AddingOddNumbers extends ConsoleProgram { public void run() { int n = readInt("enter a positive nunber: "); int total = 0; for (int i = 0; i < n; i++) { if (n == 1) { println(1); } else { println((i * 2) + 1); } } } }

  • Iteration speed of int vs long

    - by jqno
    I have the following two programs: long startTime = System.currentTimeMillis(); for (int i = 0; i < N; i++); long endTime = System.currentTimeMillis(); System.out.println("Elapsed time: " + (endTime - startTime) + " msecs"); and long startTime = System.currentTimeMillis(); for (long i = 0; i < N; i++); long endTime = System.currentTimeMillis(); System.out.println("Elapsed time: " + (endTime - startTime) + " msecs"); Note: the only difference is the type of the loop variable (int and long). When I run this, the first program consistently prints between 0 and 16 msecs, regardless of the value of N. The second takes a lot longer. For N == Integer.MAX_VALUE, it runs in about 1800 msecs on my machine. The run time appears to be more or less linear in N. So why is this? I suppose the JIT-compiler optimizes the int loop to death. And for good reason, because obviously it doesn't do anything. But why doesn't it do so for the long loop as well? A colleague thought we might be measuring the JIT compiler doing its work in the long loop, but since the run time seems to be linear in N, this probably isn't the case.

  • Sending Illegal XML Characters in Soap Request

    - by SK
    I am trying to send special (&, ' (single quote)) characters in the Soap Request. I am using axis 1.4. The webservice client is in weblogic server and the webservice server is an ibm mainframe (COBOL program). The request data from the client contains special character (& symbol) which is converted to &amp; I tried to enclose it with CDATA as <![CDATA[Some Name & Some Data ]]> which got converted to &lt;![CDATA[Some Name &amp; Some Data]]&gt; The webservice client is generated from wsdl, so I couldn't use CDATA api to construct the request. I am able to set it as string value, and it is getting converted. Any help on this would be greatly appreciated. Please let me know if you need any more information on this.

  • How do you marshall a parameterized type with JAX-WS / JAXB?

    - by LES2
    Consider the following classes (please assume public getter and setter methods for the private fields). // contains a bunch of properties public abstract class Person { private String name; } // adds some properties specific to teachers public class Teacher extends Person { private int salary; } // adds some properties specific to students public class Student extends Person { private String course; } // adds some properties that apply to an entire group of people public class Result<T extends Person> { private List<T> group; private String city; // ... } We might have the following web service implementation annotated as follows: @WebService public class PersonService { @WebMethod public Result<Teacher> getTeachers() { ... } @WebMethod public Result<Student> getStudents() { ... } } The problem is that JAXB appears to marshall the Result object as a Result<Person> instead of the concrete type. So the Result returned by getTeachers() is serialized as containing a List<Person> instead of List<Teacher>, and the same for getStudents(), mutatis mutandis. Is this the expected behavior? Do I need to use @XmlSeeAlso on Person? Thanks! LES

  • Spring ROO issue with UrlRewrite in STS (eclipse)

    Hi. I'm having trouble figuring out how to solve this issue. I have a file called: "urlrewrite.xml" which was automatically generated by spring ROO after running the "controller" command in ROO Shell.

  • Validating XML using XSD with regex pattern

    - by Steel Plume
    Hello, I am parsing a XML file against a XSD containing some regex patterns used for checking input data, but only this regex generates an error, even if it passes into the Eclipse XSD plugin: InvalidRegex: Pattern value '(((com|it|org)\.)+(\b[a-z]+[.]{1}\b)+)?[A-Z]{1}[A-Za-z]+' is not a valid regular expression. The reported error was: 'This expression is not supported in the current option setting.'. So, with SAX validator where can I find the fatal "current option setting"?
