  • Textbox height in a small browser window

    - by Fritz H
    Hi folks, I have here a peculiar problem. We have a RAP application intended for use on a PDA/phone, but when it is displayed in a small browser window, all the textboxes on the form(s) are too tall (around twice the height they should be). I've stepped through the code (The form is using GridLayout, number of columns=1, make columns equal=false) and have found that the TextSizeDetermination.getCharHeight() method returns an incorrect font size if the browser window is too small - 13px if the window is large, 26px (exactly double) if the window is too small. Interestingly enough, it seems that if the window is too small, probeStore.containsProbeResult(font) in that method returns true and uses probeStore.getProbeResult(...).getSize().y for the font size. Otherwise, if the window is larger, it returns false and uses TextSizeEstimation.getCharHeight(...). Does anyone have a pointer or two for getting around this? Dialog with a properly-sized window: Dialog with a small window:

  • How to create an aspect on class, that is not a bean using Spring AOP?

    - by Ula Krukar
    Hello, I work on an legacy application, where Spring AOP (namely ProxyFactoryBean) is used. I need to add an aspect around a method of a certain class. This class is not a bean however. The AspecjJ pointcut expression would be like this: execution(* xyz.package.Class.method()) I created a MethodInterceptor and AspectJExpressionPointcut, but I don't know how make those two work together. EDIT: I do not have source code for this class, it is a 3rd party library. The instances of this class are not created by me, neither in source code, nor in spring configuration as beans. It is used internally by the library. Any help appreciated.

  • Trouble making OAuth signed requests

    - by behrk2
    Hello, I am able to successfully make non-authenticated and protected calls to the Netflix API. I am having a little trouble making signed requests to the catalog, however. Using the OAuth Test page, it is clear to me that my Base String is correct. My request URL is also correct, except for the oauth_signature. The oauth_signature is the only thing that differs. If I understand correctly, the only difference between a protected call and a signed call is that there are no tokens involved, and that I am appending on call parameters (such as term). So, I am using the exact same code that I use for my protected calls that I am for my signed calls, except my signature key ONLY contains my shared secret (with an ampersand sign on the end of it). It does not use the access token. Am I missing something here? Where else can I be going wrong? Thanks!

  • Object Slicing, Is it advantage ?

    - by harigm
    Object slicing is some thing that object looses some of its attributes or functions when a child class is assigned to base class. Some thing like Class A{ } Class B extends A{ } Class SomeClass{ A a = new A(); B b = new B(); // Some where if might happen like this */ a = b; (Object slicing happens) } Do we say Object slicing is any beneficial in any ways? If yes, can any one please tell me how object slicing be a helpful in development and where it might be helpful?

  • Reading string value from Excel with HSSF but it's double

    - by egaga
    Hi, I'm using HSSF-POI for reading excel data. The problem is I have values in a cell that look like a number but really are strings. If I look at the format cell in Excel, it says the type is "text". Still the HSSF Cell thinks it's numeric. How can I get the value as a string? If I try to use cell.getRichStringValue, I get exception; if cell.toString, it's not the exact same value as in Excel sheet. Thanks! edit: until this gets resolved, I'll use new BigDecimal(cell.getNumericCellValue()).toString()

  • Space-based architecture?

    - by rcampbell
    One chapter in Pragmatic Programmer recommends looking at a blackboard/space-based architecture + a rules engine as a more flexible alternative to a traditional workflow system. The project I'm working on currently uses a workflow engine, but I'd like to evaluate alternatives. I really feel like a SBA would be a better solution to our business problems, but I'm worried about a total lack of community support/user base/venders/options. JavaSpaces is dead, and the JINI spin-off Apache River seems to be on life support. SemiSpace looks perfect, but it's a one-man show. The only viable solution seems to be GigaSpaces. I'd like to hear your thoughts on space based architecture and any experiences you've had with real world implementations.

  • How to allow anonymous login in org.apache.ftpserver?

    - by ablmf
    I wrote a little code like this to start an ftp server embedded in my application. It's based on apache ftpserver I found that anonymous user could not login. Client keeps get 530. Do I have add a configure file for ftp? I can not find any API to create a User to add to UserManger. private void start_ftp() throws FtpException { FtpServerFactory serverFactory = new FtpServerFactory(); ListenerFactory factory = new ListenerFactory(); // set the port of the listener factory.setPort(DEF_FTP_PORT); // replace the default listener serverFactory.addListener("default", factory.createListener()); Ftplet fl = new MyFtplet(); Map<String, Ftplet> map_ftplest = new LinkedHashMap<String, Ftplet>(); map_ftplest.put("default", fl); serverFactory.setFtplets(map_ftplest); UserManagerFactory u_factory = new PropertiesUserManagerFactory(); UserManager u_manager = u_factory.createUserManager(); //u_manager. Boolean b = u_manager.doesExist("anonymous"); serverFactory.setUserManager(u_manager); // start the server server = serverFactory.createServer(); server.start(); }

  • Detecting when a handler couldn't be started when embedding Jetty

    - by scompt.com
    I'm embedding Jetty in a similar manner as described here. When the RequestLogHandler can't open the specified logfile, it throws an exception which is unfortunately caught by org.eclipse.jetty.server.Server and swallowed (but logged first, at least). This means that there's no obvious way for me to tell if the log handler was started correctly. Is there a way that I'm missing to detect when a handler couldn't start?

  • Emulating HTTP POST via httpclient 3.x for multi options

    - by Frankie Ribery
    I want to emulate a HTTP POST using application/x-www-form-urlencoded encoding to send a option group that allows multiple selections. <select name="groups" multiple="multiple" size="4"> <option value="2">Administration</option> <option value="1">General</option> </select> Does adding 2 NameValuePairs (NVP) with the same name work ? My serverside log shows that only the first NVP was received. e.g PostMethod method = ...; NameValuePair[] nvpairs = { new NameValuePair( "groups", "2" ); new NameValuePair( "groups", "1" ); }; method.addParameter( nvpairs ); Only the groups=1 parameter was received. Thanks

  • XStream or Simple

    - by Adeel Ansari
    I need to decide on which one to use. My case is pretty simple. I need to convert a simple POJO/Bean to XML, and then back. Nothing special. One thing I am looking for is it should include the parent properties as well. Best would be if it can work on super type, which can be just a marker interface. If anyone can compare these two with cons and pros, and which thing is missing in which one. I know that XStream supports JSON too, thats a plus. But Simple looked simpler in a glance, if we set JSON aside. Whats the future of Simple in terms of development and community? XStream is quite popular I believe, even the word, "XStream", hit many threads on SO. Thanks.

  • VARCHAR does not work as expected in Apache Derby

    - by Tom Brito
    I'm having this same problem: How can I truncate a VARCHAR to the table field length AUTOMATICALLY in Derby using SQL? To be specific: CREATE TABLE A ( B VARCHAR(2) ); INSERT INTO A B VALUES ('1234'); would throw a SQLException: A truncation error was encountered trying to shrink VARCHAR '123' to length 2. that is already answered: No. You should chop it off after checking the meta-data. Or if you don't wanna check the meta-data everytime, then you must keep both your code and database in sync. But thats not a big deal, its a usual practice in validators. but my doubt is: isn't VARCHAR suppose to variate its size to fit the data? What's wrong with apache derby's VARCHAR?

  • How to get IzPack tocheck for an existing version of the software?

    - by bguiz
    Hi, I have an application for which we use IzPack to create the installer. The installer is working fine in its current state, however, I need to add functionality that enables it to check whether an existing version of the software has been installed. I understand IzPack supports this out of the box using its CheckedHelloPanel, unfortunately that only works for Windows, as it appears to depend on the windows registry. Is there a way to configure IzPack such that it is able to detect existing installations? I need to be able to detect whether there is one and merely display a message notifying the user... Bonus points for how to give the user the option to trigger the uninstaller of the existing installation. Assume that the software will only be installed using the new installer IzPack only: please do not suggest alternatives, as we cannot change that now If you suggest using <validator>, please include a code sample of the validator class, because I have considered this, but don't know where to start

    I am working on a Scrollable Image field.I am handling TouchEvent.DOWN mTouchEvent.MOVE,TouchEvent.UP. Somehow control never goes to TouchEvent.UP section.How to capture the UP event. I have to findout the start and end points of the drag. My Code looks like this.. if (event == TouchEvent.DOWN && touchEvent.isValid()) { _xTouch = touchEvent.getX(1); _yTouch = touchEvent.getY(1); } else if(event == TouchEvent.UP && touchEvent.isValid()) { int x = touchEvent.getX(1); int y = touchEvent.getY(1); } else if (event == TouchEvent.MOVE && touchEvent.isValid()) { boolean result = scrollImage((touchEvent.getX(1) - _xTouch), (touchEvent.getY(1) - _yTouch)); _xTouch = touchEvent.getX(1); _yTouch = touchEvent.getY(1); //If scrolling occurred, consume the touch event. if (result) { return true; } else { return false; } } Thanks in advance.
