  • 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:

  • Why can I not deploy my ear on Glassfish

    - by hexin
    I have standard maven project in netbeans (netbeans' enterprise application), that have 1 war, 1 ejb and 1 ear modules. I want to inject with @Inject my @Stateless from ejb to war (REST class) using its interface. I have added some beans.xml files in correct folders in project, but im still getting this: Error occurred during deployment: Exception while loading the app : WELD-001409 Ambiguous dependencies for type [LogicBean] with qualifiers [@Default] at injection point [[field] @Inject private pl.edu.amu.wmi.kino.rk.rest.ReportRest.bean].

Please see server.log for more details. What am i doing wrong? I have searched the whole internet, but could not find the solution. I know it is possible because i worked on a project with such a staff. THX for any help:)

  • Ghost activity in android

    - by Ari
    My application works as follow: On start I have some AppStartActivity which does something, finishes itself and starts MainActivity if user is logged in or LoginActivity otherwise. LoginActivity finishes itself and starts MainActivity when user log in successfully. On MainActivity I have SomeActivity from which user can logout. Activity stack for this situation is MainActivity > SomeActivity. It is correct, back button works well. When user click LogOut button there is a problem. I need to show LoginActivity but I don't want to have MainActivity and SomeActivity on activity stack anymore. I could resolve this problem if I wouldn't finish AppStartActivity. I could go back then with flag FLAG_ACTIVITY_CLEAR_TOP and it would work well. But here is a problem with back button. I don't want user to come back to this activity with back button. I want it to exit app instead. UPDATED: Flags FLAG_ACTIVITY_NEW_TASK and FLAG_ACTIVITY_CLEAR_TASK would be best, but I need it working in API level 9.

  • 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

  • How to integrate Guice 2 into Wicket?

    - by deamon
    I want to use Guice 2 with Wicket 1.4. There is a "wicket-guice" package, which uses Guice 1. Can someone give me an example how to configure Wicket to use Guice 2 for injection (with Maven). As you can see blow, I've found a solution, but I wonder, if it would be better to use Guice Servlets and register the whole Wicket Application as a ServletFilter with Guice. But I think this would conflict with wickets object creation strategy.

  • getting JSlider bar to move on mouse click event

    - by Aly
    Hi, I have a JSlider which shows bet sizes (for a poker game) I am trying to achieve the effect that when a mouse click occurs the slider jumps forward by a bet amount (i.e. a big blind amount) rather than just incrementing by one. If the mouse click happens to the left of the bar i want it to decrement by a fixed amount else increment. I looked into attaching a mouse listener, but do not know how I can use the event to find out on what side of the bar the mouse was clicked. Any ideas?

  • Spring validation errors not displayed

    - by Art Vandelay
    I have the following situation. I have a validator to validate my command object and set the errors on a Errors object to be displayed in my form. The validator is invoked as expected and works okay, but the errors i set on the Errors objects are not displayed, when i am sent back to my form because of the validation errors. Validator: public void validate(Object obj, Errors err) { MyCommand myCommand = (MyCommand) obj; int index = 0; for (Field field : myCommand.getFields()) { if (field.isChecked()) { if ((field.getValue() == null) || (field.getValue().equals(""))) { err.rejectValue("fields[" + index + "].value", "errors.missing"); } } index++; } if (myCommand.getLimit() < 0) { err.rejectValue("limit", "errors.invalid"); } } Command: public class MyCommand { private List<Field> fields; private int limit; //getters and setters } public class Field { private boolean checked; private String name; private String value; //getters and setters } Form: <form:form id="myForm" method="POST" action="${url}" commandName="myCommand"> <c:forEach items="${myCommand.fields}" var="field" varStatus="status"> <form:checkbox path="fields[${status.index}].checked" value="${field.checked}" /> <c:out value="${field.name}" /> <form:input path="fields[${status.index}].value" /> <form:errors path="fields[${status.index}].value" cssClass="error" /></td> <form:hidden path="fields[${status.index}].name" /> </c:forEach> <fmt:message key="label.limit" /> <form:input path="limit" /> <form:errors path="limit" cssClass="error" /> </form:form> Controller: @RequestMapping(value = REQ_MAPPING, method = RequestMethod.POST) public String onSubmit(Model model, MyCommand myCommand, BindingResult result) { // validate myCommandValidator.validate(myCommand, result); if (result.hasErrors()) { model.addAttribute("myCommand", myCommand); return VIEW; } // form is okay, do stuff and redirect } Could it be that the paths i give in the validator and tag are not correct? The validator validates a command object containing a list of objects, so that's why i give a index on the list in the command object when registering an error message (for example: "fields["+index+"]".value). Or is it that the Errors object containing the errors is not available to my view? Any help is welcome and appreciated, it might give me a hint or point me in right direction.

  • InvalidAttributeValueException when using non-ascii characters in JNDI

    - by matdan
    Hi, I have some trouble using JNDI since it accepts only 7-bits encoded parameters. I am trying to change an LDAP entry using JNDI with the following code : Attribute newattr = new BasicAttribute("userpassword", password); ModificationItem[] mods = new ModificationItem[1]; mods[0] = new ModificationItem(DirContext.REPLACE_ATTRIBUTE, newattr); context.modifyAttributes("uid=anID,ou=People,o=MyOrganisation,c=com", mods); If my password contains only ascii characters, it works perfectly, but if I use a non-ascii character, like "à", I have this error message : javax.naming.directory.InvalidAttributeValueException: [LDAP: error code 19 - The value is not 7-bit clean: à]; My ldap supports those characters so I guess it comes from JNDI. Does anyone know how to fix that? Am I supposed to convert my parameter? How can I do that easily? Thanks

    - 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?

  • How To Generate Parameter Set for the Diffie-Hellman Key Agreement Algorithm in Android

    - by sebby_zml
    Hello everyone, I am working on mobile/server security related project. I am now stuck in generating a Diffie-Hellman key agreement part. It works fine in server side program but it is not working in mobile side. Thus, I assume that it is not compactible with Android. I used the following class to get the parameters. It returns a comma-separated string of 3 values. The first number is the prime modulus P. The second number is the base generator G. The third number is bit size of the random exponent L. My question is is there anything wrong with the code or it is not compactible for android?What kind of changes should I do? Your suggestion and guidance would be very much help for me. Thanks a lot in advance. public static String genDhParams() { try { // Create the parameter generator for a 1024-bit DH key pair AlgorithmParameterGenerator paramGen = AlgorithmParameterGenerator.getInstance("DH"); paramGen.init(1024); // Generate the parameters AlgorithmParameters params = paramGen.generateParameters(); DHParameterSpec dhSpec = (DHParameterSpec)params.getParameterSpec(DHParameterSpec.class); // Return the three values in a string return ""+dhSpec.getP()+","+dhSpec.getG()+","+dhSpec.getL(); } catch (NoSuchAlgorithmException e) { } catch (InvalidParameterSpecException e) { } return null; } Regards, Sebby

  • How can I import one Gradle script into another?

    - by Ant
    Hi all, I have a complex gradle script that wraps up a load of functionality around building and deploying a number of netbeans projects to a number of environments. The script works very well, but in essence it is all configured through half a dozen maps holding project and environment information. I want to abstract the tasks away into another file, so that I can simply define my maps in a simple build file, and import the tasks from the other file. In this way, I can use the same core tasks for a number of projects and configure those projects with a simple set of maps. Can anyone tell me how I can import one gradle file into another, in a similar manner to Ant's task? I've trawled Gradle's docs to no avail so far. Additional Info After Tom's response below, I thought I'd try and clarify exactly what I mean. Basically I have a gradle script which runs a number of subprojects. However, the subprojects are all Netbeans projects, and come with their own ant build scripts, so I have tasks in gradle to call each of these. My problem is that I have some configuration at the top of the file, such as: projects = [ [name:"MySubproject1", shortname: "sub1", env:"mainEnv", cvs_module="mod1"], [name:"MySubproject2", shortname: "sub2", env:"altEnv", cvs_module="mod2"] ] I then generate tasks such as: projects.each({ task "checkout_$it.shortname" << { // Code to for example check module out from cvs using config from 'it'. } }) I have many of these sort of task generation snippets, and all of them are generic - they entirely depend on the config in the projects list. So what I want is a way to put this in a separate script and import it in the following sort of way: projects = [ [name:"MySubproject1", shortname: "sub1", env:"mainEnv", cvs_module="mod1"], [name:"MySubproject2", shortname: "sub2", env:"altEnv", cvs_module="mod2"] ] import("tasks.gradle") // This will import and run the script so that all tasks are generated for the projects given above. So in this example, tasks.gradle will have all the generic task generation code in, and will get run for the projects defined in the main build.gradle file. In this way, tasks.gradle is a file that can be used by all large projects that consist of a number of sub-projects with Netbeans ant build files.

  • Is it possible to make web app proactive rather than reactive?

    - by Ari B.
    Web applications traditionally follow the request/response cycle, where a request is made by a user or another web app. However, I'm curious if it is possible to make a web app automatically initiate certain tasks upon it's deployment to a app server. For example, let's say we have a web app that retrieves and processes data. Is it possible to configure this app to automatically retrieve and process data when certain criteria are met, rather than needing a request from a user/another web app?

  • Accessing Spring beans from a Tiles view (JSP)

    - by Sinuhe
    In Spring MVC I can access my beans in JSP using JstlView's exposedContextBeanNames (or exposeContextBeansAsAttributes). For example, then, in my JSP I can write (${properties.myProperty). But when the same JSP is a part of a tiles view, these properties aren't accessible. Is possible to configure Tiles properly or access these properties in another way? I'm using Spring MVC 3.0.2 and Tiles 2.2.1. Here's a bit of my configuration: <bean id="tilesViewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver"> <property name="order" value="1"/> <property name="viewClass" value="org.springframework.web.servlet.view.tiles2.TilesView" /> </bean> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/> <property name="order" value="2"/> <property name="prefix" value="/WEB-INF/views/"/> <property name="suffix" value=".jsp"/> <property name="exposedContextBeanNames"> <list><value>properties</value></list> </property> </bean>

  • Adding an HTTP Header to the request in a servlet filter

    - by Mason
    I'm integrating with an existing servlet that pulls some properties out of the HTTP header. Basically, I'm implementing an interface that doesn't have access to the actual request, it just has access to a map of k-v for the HTTP headers. I need to pass in a request parameter. The plan is to use a servlet filter to go from parameter to header value but of course the HttpServletRequest object doesn't have an addHeader() method. Any ideas?

  • controlling threads flow

    - by owca
    I had a task to write simple game simulating two players picking up 1-3 matches one after another until the pile is gone. I managed to do it for computer choosing random value of matches but now I'd like to go further and allow humans to play the game. Here's what I already have : http://paste.pocoo.org/show/201761/ Class Player is a computer player, and PlayerMan should be human being. Problem is, that thread of PlayerMan should wait until proper value of matches is given but I cannot make it work this way. Logic is as follows: thread runs until matches equals to zero. If player number is correct at the moment function pickMatches() is called. After decreasing number of matches on table, thread should wait and another thread should be notified. I know I must use wait() and notify() but I can't place them right. Class Shared keeps the value of current player, and also amount of matches. public void suspendThread() { suspended = true; } public void resumeThread() { suspended = false; } @Override public void run(){ int matches=1; int which = 0; int tmp=0; Shared data = this.selectData(); String name = this.returnName(); int number = this.getNumber(); while(data.getMatches() != 0){ while(!suspended){ try{ which = data.getCurrent(); if(number == which){ matches = pickMatches(); tmp = data.getMatches() - matches; data.setMatches(tmp, number); if(data.getMatches() == 0){ System.out.println(" "+ name+" takes "+matches+" matches."); System.out.println("Winner is player: "+name); stop(); } System.out.println(" "+ name+" takes "+matches+" matches."); if(number != 0){ data.setCurrent(0); } else{ data.setCurrent(1); } } this.suspendThread(); notifyAll(); wait(); }catch(InterruptedException exc) {} } } } @Override synchronized public int pickMatches(){ Scanner scanner = new Scanner(System.in); int n = 0; Shared data = this.selectData(); System.out.println("Choose amount of matches (from 1 to 3): "); if(data.getMatches() == 1){ System.out.println("There's only 1 match left !"); while(n != 1){ n = scanner.nextInt(); } } else{ do{ n = scanner.nextInt(); } while(n <= 1 && n >= 3); } return n; } }
