  • How to set Camera View as background with views over it?

    - by Android Student
    So, I'm trying to make the background to one of my apps look "futuristic." I thought of an idea to make the screen look almost transparent yet have views over it. So, it would look something like this: I'm thinking that I can use the camera to capture the background of the phone (without taking a picture, just having the real time view in the background) and then, if possible, place a semi-transparent slightly blurred ImageView over that. Finally, on top of that I can place the other views including the ImageButtons. So, my question is how would I go about doing this? I have searched but haven't found anything relevant. It must be possible; its just how to do it? I don't expect you to give me all the code as an answer, just if you have any ideas that can help or links or code that can point me in the right direction, it would be greatly appreciated! Thanks!

  • How to see full compile path in Eclipse?

    - by alleywayjack
    I have looked for an answer for this nearly every where that I can think of, but there doesn't seem to be any way to actually SEE what Eclipse "runs" to compile the projects (as it does need the JDK installed and visible to actually build). I ask because I imported a few jars into my project, and even though I've looked through all the javac documentation, I can't seem to figure out how to mimic it quite like Eclipse does. I really, really need to be able to compile on the command line in this case - Eclipse or any other IDE just isn't what is needed. I started to look through the Eclipse source, and although this sounds lazy, I just became overwhelmed and figured I would ask here first, hoping someone else had the same question at one point.

  • What does the exception "javax.servlet.jsp.JspException: Broken pipe" signify?

    - by Ruepen
    I'm getting the following error: javax.servlet.jsp.JspException: Broken pipe Now I have seen questions/answers with respects to the socket exception, but this error is coming from a different package. Any help is greatly appreciated. BTW, I am seeing quite a lot of these errors in a struts web app Weblogic Node logs and I am thinking that it has to do with end users closing their web browser before the page reloads/executes the next step (database transaction which takes quite a bit of time to execute, anywhere from 30 seconds to 4 mins).

  • Decoding international chars in AppEngine

    - by Irro
    I'm making a small project in Google AppEngine but I'm having problems with international chars. My program takes data from the user through the url "page.html?data1&data2..." and stores it for displaying later. But when the user are using some international characters like åäö it gets coded as %F4, %F5 and %F6. I assume it is because only the first 128(?) chars in ASCII table are allowed in http-requests. Is there anyone who has a good solution for this? Any simple way to decode the text? And is it better to decode it before I store the data or should I decode it when displaying it to the user.

  • Android - Fill Layout with Buttons

    - by GuyNoir
    Just a quick question about how you would go about implementing this. I want there to be buttons at the bottom of the screen, but if the screen size is larger, more buttons would be added. For example, at a small screen size, there might be 4-5 buttons at the bottom, but if you ran it on a tablet or something similar, there would be maybe 20 buttons. Any suggestions? It can't scroll either, it just has to dynamically fill the layout with buttons. Thanks.

  • doubt in Exceptions

    - by Ajay Singh
    class MyException extends Exception { MyException() {} MyException(String msg) { super(msg);} } public class NewException { static void f() throws MyException { System.out.println("throwing exception from f()"); throw new ClassCastException(); } static void g() throws MyException { System.out.println("throwing exception from g()"); throw new MyException("parametrized "); } public static void main(String ...strings ) { try { f(); } catch(MyException e) { e.printStackTrace(System.out); } try { g(); } catch(MyException e) { e.printStackTrace(System.out); } } } In the function f() iam specifying that "MyException " exception will be thrown and actually iam throwing some other exception which has no relation with MyException but still the compiler does not report any complain.Why is it so??

  • Ignoring all line feeds in a FreeMarker template

    - by Will
    I'm trying out FreeMarker, not for a web application but to generate text within a desktop application. I'd like to get the text without any linefeeds, however it always appends a linefeed. For example, this would produce "blah blah\n" <#if docType=1> blah blah <#if docType=2> more blah <#/if> Any ideas? Bunching it all into one line works, but is horrible. Thanks.

  • How to create GUI as inner class with WindowBuilder

    - by Tim Kemp
    I would like to use WindowBuilder in Eclipse to construct Swing GUIs. The JPanels I need to build will be inner classes in a non-GUI wrapper, like so: public class MyWrapper extends MyBaseClass { ... class MyPanel extends JPanel { ... } } So my question is this: can I construct MyPanel using WindowBuilder? If so, how should I set it up? If anyone is interested, the wrapper is an abstract base class which the plug-ins I am developing for my app must extend; deployment concerns mean that it's not really practical to put the GUIs in a separate JAR either so I pretty much have to do it this way. My current workflow, which is awful, is to build the GUI in NetBeans and paste the entire generated class into Eclipse where I connect it up to the methods in my wrapper. I am very hopeful that WindowBuilder will let me work more reliably and efficiently if I can trick it into generating code in MyPanel, not MyWrapper. Thanks

  • How to define a url not found servlet mapping in web.xml?

    - by user246114
    Hi, I have a web app, I want to define my index.jsp file to be shown when the entered url is like: www.mysite.com www.mysite.com/ www.mysite.com/index.jsp but if any other url is entered, like: wwww.mysite.com/g I want a particular servlet to handle the request. In my web.xml file, I am doing this: <servlet> <servlet-name>ServletCore</servlet-name> <servlet-class>com.me.test.ServletCore</servlet-class> </servlet> <servlet-mapping> <servlet-name>ServletCore</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> so that is letting the ServletCore servlet pick up any url, but as expected it is taking over even the: www.mysite.com/index.jsp type urls. How can I define it in such a way to work how I want? Thank you

  • if a JAR is placed on app servers's classpath how do we reference it from JSP

    - by Omnipresent
    On our application we are getting an error saying: PWC6117: File "/struts-tags" not found code in the file thats giving error is: <%@ taglib prefix="s" uri="/struts-tags" %> This file is in struts2-core.jar which is placed on the classpath of the app server (Sun 9.1). The code will work fine and not complain when the jar is actually in WEB-INF/lib of the application, compared to being on classpath of the appserver. But we can not change that. it has to be on appservers classpath. But how should we change our code so that this error goes away? I can create mapping in my web.xml so that tag uri's are change. but what should taglib-location be changed to? so that it references to app servers classpath? <taglib> <taglib-uri>/WEB-INF/struts-tags.tld</taglib-uri> <taglib-location>/WEB-INF/struts-tags.tld</taglib-location> </taglib>

  • using AutoCompleteTextField in wicket without String as the generic type

    - by Manuel
    Hi! This question follows this: handling to onchange event of AutoCompleteTextField in wicket I'm trying to use the AutoCompleteTextField with a custom class as the generic type, and to add an AjaxFormComponentUpdatingBehavior. What I mean is I want to have a AutoCompleteTextField<SomeClass> myAutoComplete = ...; and after that add a AjaxFormComponentUpdatingBehavior: myAutoComplete.add(new AjaxFormComponentUpdatingBehavior("onchange") { @Override protected void onUpdate(AjaxRequestTarget target) { System.out.println( "Value: "+getValue() ); } }); The problem is that for some reason, adding that behavior makes the form try to set the model object with a String (even though the AutoCompleteTextField has a generic type of SomeClass), causing a ClassCastException when the onchange event fires. Is there a way to use AutoCompleteTextField without it being AutoCompleteTextField<String>? I couldn't find any example. Thanks for your time! and thanks to the user biziclop for his help in this matter.

  • Confusion with a while statement evaluating if a number is triangular

    - by Darkkurama
    I've been having troubles trying to figure out how to solve a function. I've been assigned the development of a little programme which tells if a number is "triangular" (a number is triangular when the addition of certain consecutive numbers in the [1,n] interval is n. Following the definition, the number 10 is triangular, because in the [1,10] interval, 1+2+3+4=10). I've coded this so far: class TriangularNumber{ boolean numTriangular(int n) { boolean triangular = false; int i = n; while(n>=0 && triangular){ //UE06 is a class which contains the function "f0", which makes the addition of all the numbers in a determined interval UE06 p = new UE06(); if ((p.f0(1, i))==n) triangular = true; else i=i-1; } return triangular; } boolean testTriangular = numTriangular(10) == true && numTriangular(7) == false && numTriangular(6) == true; public static void main(String[] args){ TriangularNumber p = new TriangularNumber(); System.out.println("testTriangular = " + p.testTriangular); } } According to those boolean tests I made, the function is wrong. As I see the function, it goes like this: I state that the input number in the initial state isn't triangular (triangular=false) and i=n (determining the interval [1,i] where the function is going to be evaluated While n is greater or equals 0 and the number isn't triangular, the loop starts The loop goes like this: if the addition of all the numbers in the [1,i] interval is n, the number is triangular, causing the loop to end. If that statement is false, i goes from i to (i-1), starting the loop again with that particular interval, and so on till the addition is n. I can't spot the error in my "algorithm", any advice? Thanks!

  • what is the purpose of getEventType() method in XMLStreamReader Class

    - by KItis
    I have sample code written for parsing xml file using javax.xml package. it uses the method called getEventType() , but I can not understand the purpose of this method. i wrote simple application to understand its usefulness, but it output only some random numbers for which I can not make any sense, could some one help me to get this point right. Here is the sample code I have written. public List parseXML(File f) throws XMLStreamException{ xmlInputFactory = new WstxInputFactory(); xmlInputFactory.setProperty(XMLInputFactory2.IS_REPLACING_ENTITY_REFERENCES, Boolean.FALSE); xmlInputFactory.setProperty(XMLInputFactory2.IS_SUPPORTING_EXTERNAL_ENTITIES, Boolean.FALSE); xmlInputFactory.setProperty(XMLInputFactory2.IS_COALESCING,Boolean.FALSE); xmlInputFactory.setProperty(XMLInputFactory2.IS_VALIDATING,Boolean.FALSE); xmlInputFactory.configureForSpeed(); List<Task> tasks = new LinkedList<Task>(); //xmlStreamReader = xmlInputFactory.createXMLStreamReader(new StringReader(dmml)); xmlStreamReader = xmlInputFactory.createXMLStreamReader(f); int eventType = xmlStreamReader.getEventType(); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); /*String currentElement = ""; String currentElementText = ""; }

  • How to trigger the specific controller action using a button?

    - by Eugene
    I'm creating a simple training project. I've implemented a controller method, which deletes an item from the list. The method is looking like this: @Controller @RequestMapping(value = "/topic") public class TopicController { @Autowired private TopicService service; ... @RequestMapping(value = "/deleteComment/{commentId}", method = RequestMethod.POST) public String deleteComment(@PathVariable int commentId, BindingResult result, Model model){ Comment deletedComment = commentService.findCommentByID(commentId); if (deletedComment != null) { commentService.deleteComment(deletedComment); } return "refresh:"; } } This method is called from the button-tag, which is looking in the following way: _form> _button formaction = "../deleteComment/1" formmethod = "post">delete_/button> _/form> Sorry, but in the form tag I've changed all the '<' characters with the '_', because the tag was invisible. In my project the form-tag is looking like a cliuckable button. But there is a serious problem: controller's method is never triggered. How can I trigger it, using a button-tag? P.S. the call is performed from the page with URI http://localhost:8080/simpleblog/topic/details/2 and controller's URI is the http://localhost:8080/simpleblog/topic/deleteComment/2

  • JPanel superclass doesn't add the components of its subclasses..

    - by Acryl
    Well, I use a JFrame that adds two JPanels. Those JPanels are superclasses, because I find it easier to separate different areas of the GUI into different classes. But here's the problem: I add the (superclass) JPanel to the JFrame I set the layout of the superclass JPanel to new BorderLayout(); I add components in the subclasses, like this: JPanel panel = new JPanel(); panel.setLayout(new GridLayout(2,1)); panel.add(new JLabel("Label:"); panel.add(new JTextField(); add(panel, BorderLayout.NORTH); But it doesn't show. What do I do wrong? I've tried it without an additional JPanel in the subclasses, but it doesn't work either. I use jdk 1.6

  • PreparedStatement.setString() method without quotes

    - by Slavko
    I'm trying to use a PreparedStatement with code similar to this: SELECT * FROM ? WHERE name = ? Obviously, what happens when I use setString() to set the table and name field is this: SELECT * FROM 'my_table' WHERE name = 'whatever' and the query doesn't work. Is there a way to set the String without quotes so the line looks like this: SELECT * FROM my_table WHERE name = 'whatever' or should I just give it up and use the regular Statement instead (the arguments come from another part of the system, neither of those is entered by a user)?
