  • package private static member class vs. package private class

    - by Helper Method
    I was writing two implementations of a linked list for an assignment, a doubly linked list and a circular doubly linked list. Now as the class representing a Link within the linked list is the same in both implementations, I want to use it in both. Now I wonder which approach would be better: Implement the Link class as a package private static member class in the first implementation and then use this class in the second implementation or make the Link class a package private class.

  • Spring MVC: easiest way to see incoming requests

    - by flybywire
    I am debugging a Spring MVC (3.0) app, deployed on tomcat. I want to see in my console or log files all the incoming requests. Including 404s, both generated by my app or by spring because it didn't find an appropriate controller. I'd like to see something like this: GET /index.html GET /img/logo.png GET /js/a.js GET /style/b.css POST /ajax/dothis?blah=yes POST /ajax/dothat?foo=np GET /nextpage.html ... What is the easiest way to see that.

  • Using a custom annotation on a Spring MVC controller method from an interceptor.

    - by Speck
    I have a custom annotation with which I've annotated a method in my Controller alongside a @ReqestMapping. The goal is to use the values set in the custom annotation from a HandlerInterceptor to perform a task. I have the interceptor (HandlerInterceptorAdaptor) mapped and it executes. If I set a breakpoint in my concrete Interceptor I can inspect the HttpServletRequest, HttpServletResponse, and handler Objects. However, I cannot see how to 1, obtain the method which the request is trying to access 2, obtain the Annotations on that method and 3, of course, obtain the values set by the annotation. Can anyone point me to good documentation for this? Please and Thank You.

  • Add Method to Built In Class

    - by Evorlor
    I am pretty sure this is not doable, but I will go ahead and cross my fingers and ask. I am trying to add a method to a built in class. I want this method to be callable by all of the built in class's subclasses. Specifically: I have a JButton, a JTextPane, and other JComponents. I want to be able to pass in a JDom Element instead of a Rectangle to setBounds(). My current solution is to extend each JComponent subclass with the desired methods, but that is a LOT of duplicate code. Is there a way I can write the following method just one time, and have it callable on all JComponent objects? Or is it required that I extend each subclass individually, and copy and paste the method below? public void setBounds(Element element) { this.setBounds(Integer.parseInt(element.getAttribute( "x").toString()), Integer.parseInt(element .getAttribute("y").toString()), Integer .parseInt(element.getAttribute("width").toString()), Integer.parseInt(element.getAttribute("height") .toString())); }

  • How to detect if a form input element of type file is empty

    - by Ankur
    I have some code which reads a file through a form field of type file <input type="file" ... /> I want to give the user another option of providing a url to a file rather than having to upload it as many are already online. How can I detect when this field is empty on the server side. I am using Apache Commons FileUpload FileItemStream item = iter.next(); name = item.getFieldName(); stream = item.openStream(); if(!item.isFormField()){ if(item.toString()!=""){ .... I need to detect when item is empty. The above code doesn't work, nor does using: if(item.equals(null)){ ....

  • Is it possible to start an activity in a different apk using startActivity on Android using the acti

    - by icecream
    I have tried to write an Android application with an activity that should be launched from a different application. It is not a content provider, just an app with a gui that should not be listed among the installed applications. I have tried the code examples here and it seems to be quite easy to launch existing providers and so on, but I fail to figure out how to just write a "hidden" app and launch it from a different one. The basic use case is: App A is a normal apk launchable from the application list. App B is a different apk with known package and activity names, but is is not visible or launchable from the application list. App A launches app B using the package and class names (or perhaps a URI constructed from these?). I fail in the third step. Is it possible to do this?

  • Android - Memory leak when dynamically building UI with image resource backgrounds

    - by Rich
    I have an Activity that I swear is leaking memory. The app I'm working on does a lot with images, so I've had to be pretty stingy with memory when working directly with Bitmaps. I added an Activity, and now if you use this new Activity it basically puts me over the edge with mem usage and I end up throwing the "Bitmap exceeds VM budget" exception. If you never launch this Activity, everything is smooth as it was previously. I started reading about memory leaks, and I think that I have a similar situation to what is described in the article in the Android docs. I'm dynamically creating a bunch of image views and adding a BackgroundDrawable from the resources and adding an OnClickListener as well. I imagine I have to do some cleanup when the Activity hits onPause in its life cycle, but I'd like to know specifically what is the correct way. Here is the code that should demonstrate the objects I'm working with... LinearLayout templateContainer; . . . ImageView imgTemplatePreview = (ImageView) item.findViewById(R.id.imgTemplatePreview); . . . imgTemplatePreview.setBackgroundDrawable(getResources().getDrawable(previewId)); imgTemplatePreview.setOnClickListener(imgClick); templateContainer.addView(item);

  • GET is not working for firstResource Rest example

    - by Anandan
    Hi, I am newbie to rest. I am using the following code example to understand the RESTlet. http://www.restlet.org/documentation/1.1/firstResource I am using RESTClient addon to firefox for testing. When i do GET on http://localhost/rest, i get a response "ok". But when i do GET on http://localhost/items, I get an error "404 Not found" Here's the sample code: public synchronized Restlet createRoot() { Router router = new Router(getContext()); router.attach("/items", ItemsResource.class); router.attach("/items/{itemName}", ItemResource.class); Restlet restlet = new Restlet() { @Override public void handle(Request request, Response response) { StringBuilder stringBuilder = new StringBuilder(); stringBuilder.append("ok"); response.setEntity(new StringRepresentation(stringBuilder .toString(), MediaType.TEXT_HTML)); } }; router.attach("/rest", restlet); return router; } ItemResource is same as provided in the link. and I use tomcat to run the servlet. Why am I getting the "Not found" error? Am i missing something here? Thanks & Regards, Anandan

  • How can I get a project type on Netbeans Platform?

    - by Fabio
    Hi folks, Is there a way to know the type of a selected project? I would like to do some specific actions depending of the project type like a J2SE project. Below is the only way that I found to do that: public final class MyAction extends CookieAction { @Override public boolean isEnabled() { if(this.getActivatedNodes() == null || this.getActivatedNodes().length != 1) { return false; } Lookup lookup = this.getActivatedNodes()[0].getLookup(); // gets the selected project Project currentProject = lookup.lookup(Project.class); // checks if the selected project is a J2SE Project or a Maven Project if(currentProject != null && (currentProject.getClass().getSimpleName().equals("J2SEProject") || currentProject.getClass().getSimpleName().equals("NbMavenProjectImpl"))) { return true; } return false; }}

  • custom ListView --Null pointer exception

    - by raghs
    this code throws a Null pointer exception. It was thrown by getChildAt(i). The getCount() returns the number of items in listView. But getChildAt(i) returns only if item is present in current list view. For example in a scrollable list view assume that there are 20 items. The getCount() returns 20. But getChildAt(20) returns null. Because it doesnot fit in listview. How to solve this problem?? int i,j=object.getCount(); View v=getListView(); CheckBox chk=null; for(i=0;i<j;i++) { chk=((CheckBox)((ViewGroup) v).getChildAt(i).findViewById(R.id.checkBox1)); if(chk.isChecked()) { //download the contents to specific folder in sd card } }

  • Resizing JPanel to prepare for printing without removing it from its original position

    - by Lesman
    In my program I frequently need to print various JComponents (generally JPanels) and I like them to be full-page. The way I do it now is by using the following code: g2d.scale(pf.getImageableWidth()/componentToPrint.getWidth(), pf.getImageableHeight()/componentToPrint.getHeight()); but this often stretches or otherwise deforms whatever I am trying to print, and I would much prefer to do something that re-sized intelligently, perhaps a functional version of: componentToPrint.setSize(pf.ImageableWidth(), pf.ImageableHeight); or say adding the component into a new JFrame and then setting the frame size (problem is components can't exist in two place at once). I wouldn't care if the resizing would make the rest of the GUI look terrible, as long as it is something that can easily be reset. Is there any way to do this?

  • Querying my JPA provider (Hibernate) for a collection of <Id,Name> of an entity

    - by Ittai
    Hi, I have an entity which looks something like this: Id (PK) Name Other business properties and associations... I have the need for my DAL (JPA with hibernate as provider) to return a list of the entities which correlate to some constraints (or just return them all) but instead of returning the entities themselves I'd like to receive only the Id and the Name properties. I know this can be achieved with HQL/SQL (something like: select id,name from entity where...) but I don't want to go down that road. I was thinking of somehow defining the pair a compositioned part of the entity and thought that might help me but I'm not sure that's "legal" as the Id is the PK. The logic for this scenario is to have a textbox which asynchronously queries the web-service (and through it the DAL) for the relevant entities and once an entity is selected then it is loaded as a whole and shipped to the front-end. Would appreciate any feedback, Ittai
