  • Spring MVC - JSP - Place to Store Environment Specific Constants

    - by jboyd
    Where in the Spring-MVC/JSP application would you store things that need to be accessed by both the controllers and views such as environment specific base_url's, application ids to be used in javascript and so on? I've tried creating an application scoped bean and then at the top of my JSPs, but that doesn't seem to be working. <!-- Environment --> <bean id="myEnv" class="com.myapp.MyAppEnvironment" scope="application"> <property name="baseUrl" value="http://localhost:8080/myapp/"/> <property name="videoPlayerId" value="234346565"/> </bean> And using it in the following manner <jsp:useBean id="myEnv" scope="application" type="com.myapp.MyAppEnvironment"/>

  • Android Admob is not Showing Up

    - by Brandon
    Admob is not showing up on my emulator or on the device it self. I tried with testing mode on and off. Relevant Manifest data: permissions: <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" /> meta data: <meta-data android:value="true" android:name="AD_REQUEST" /> The x's are actually my ID. My whole main.xml: <com.admob.android.ads.AdView android:id="@+id/ad" android:layout_width="fill_parent" android:layout_height="wrap_content" android:visibility="visible" android:layout_alignParentTop="true"/> Hopefully I can get this solved soon...

  • Given a number of rectangles that can be rotated, find an enclosing rectangle of minimum area

    - by efficiencyIsBliss
    So, I'm trying to implement an algorithm that takes in a number of rectangles as input and tries to pack them into a rectangle of minimum area. The rectangles can all be rotated by 90 degrees. I realize that this is similar to the bin packing problem, but I am unable to find a good algorithm that accounts for the rotation. I found a paper that discusses this at length here and while I understand the article itself, I was hoping to find something simpler. Any suggestions? -Edit- I think I misstated the problem earlier. We are given a number of rectangles, such that each can be rotated by 90 degrees. We need to find a rectangle that fits all the given rectangles such that no two rectangles overlap, while minimizing the area of the enclosing rectangle. The problem I face here is that we are asked to find the minimum, as opposed to being given an enclosing rectangle and checking if the given rectangles fit or something of that sort.

  • recommendations for firestorm dao replacement

    - by Casey
    I have taken over some code that has been using the Firestorm DAO code generator from CodeFutures. I believe that the license for this is going to be up soon, and was wondering if anyone could recommend any alternatives, open source or not, so that I can get an idea of what's out there to better make a decision.

  • Dynamically create and cast objects at runtime

    - by vaibhav bindroo
    Let's say we have 2 classes A and B public class A{ private int member1; A() { member1 = 10; } public getMember(){ return member1; } } Class B is also on the same lines except that its member variable is named member2 and gets intitialized to say 20 inside the constructor. My Requirement : At runtime , I get a string which contains a className ( could be A or B). I want to dynamically create an object of this class along with invoking the constructor. How can I achieve this . I don't want to use interfaces for common functionality of above classes Morever, later on I set the properties of this raw object using Propery Builder Bean Util class based on a list of columns . Class clazz = Class.forName("className"); Obj obj = clazz.newInstance(); How I can dynamically convert that obj to className object.

  • Why is BorderLayout calling setSize() and setBounds()?

    - by ags
    I'm trying to get my head around proper use of the different LayoutManagers to make my GUI design skills more efficient and effective. For me, that usually requires a detailed understanding of what is going on under the hood. I've found some good discussion of the interaction and consequences of a Container using BorderLayout containing a Container using FlowLayout. I understand it for the most part, but wanted to confirm my mental model and to do so I am looking at the code for BorderLayout. In the code snippet below taken from BorderLayout.layoutContainer(), note the calls to the child Component's setSize() method followed by setBounds(). Looking at the source for these methods of Component, setSize() actually calls setBounds() with the current values for Component.x and Component.y. Why is this done (and not entirely redudant?) Doesn't the setBounds() call completely overwrite the results of the setSize() call? if ((c=getChild(NORTH,ltr)) != null) { c.setSize(right - left, c.height); Dimension d = c.getPreferredSize(); c.setBounds(left, top, right - left, d.height); top += d.height + vgap; } I'm also tring to understand where/when the child Component's size is initially set (before the LayoutManager.layoutContainer() method is called). Finally, this post itself raises a "meta-question": in a situation like this, where the source is available elsewhere, is the accepteed protocol to include the entire method? Or some other way to make it easier for folks to participate in the thread? Thanks.

  • Making Eclipse behave like Visual Studio

    - by FlySwat
    I'm doing some Android dev, and I much prefer Visual Studio, but I'll have to use Eclipse for this. Has anyone made a tool that switches Eclipse to look and behave more like visual studio? I mainly can't stand its clippyesqe suggestions on how I should program (Yes, I know I have not yet used that private field! Thanks Eclipse!), or its incredibly lousy intellisense. For example, in eclipse, if I don't type "this" first, its intellisense won't realize I want to look for locally scoped members. Also, the TAB to complete VS convention is drilled into my head, and Eclipse is ENTER to complete, I could switch everything by hand but that would take hours, and I was hoping someone had some sort of theme or something that has already done it :)

  • Multi-module Maven build

    - by Don
    Hi, My project has a fairly deep graph of Maven modules. The root POM has the following plugin configured <plugins> <plugin> <groupId>org.jvnet</groupId> <artifactId>animal-sniffer</artifactId> <version>1.2</version> <configuration> <signature> <groupId>org.jvnet.animal-sniffer</groupId> <artifactId>java1.4</artifactId> <version>1.0</version> </signature> </configuration> </plugin> </plugins> If I invoke this target from the command line in the root directory via: mvn animal-sniffer:check Then it works fine as long as the current module extends (either directly or indirectly) from the root POM. However there are many children (or grandchildren) of the root module, which do not inherit from that module's POM. In this case, the goal fails because it cannot find the necessary configuration [ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] One or more required plugin parameters are invalid/missing for 'animal-sniffer:check' [0] Inside the definition for plugin 'animal-sniffer' specify the following: <configuration> ... <signature>VALUE</signature> </configuration>. When configuring this plugin in the root module, is there any way to exclude a list of sub-modules either by name, or by packaging type? Thanks, Donal

  • How to schedule an alarm so that the intent is broadcast everytime the date changes?

    - by rogerstone
    I want to schedule an alarm which throws an intent when the date changes. I know that this would do this the job alarms.setRepeating(AlarmManager.RTC_WAKEUP,triggerAtTime, interval,alarmIntent); But what is confusing me is what to put in the triggerAtTime and the interval.It says System.currentTimeMillis() timebase. I might be installing the app on any day so the TriggerAtTime should be midnight of that day and the interval would be 24 hours from there on. How can I acheive this.Can someone tell me what to put in TriggerAtTime and interval in the required format. Thanks

  • Why is my panel not positioned correctly even after setting the boundaries?

    - by nutellafella
    I'm trying to make a simple GUI with radio buttons and I grouped them into one panel. I wanted it positioned on the leftmost side so I used the setBounds method. Whatever numbers I put on the parameters, the panel won't move. Are panels not affected by the setBounds method? Or is there another way to position my panel. Here's the snippet of my code: JPanel radioPanel = new JPanel(); radioPanel.setLayout(new GridLayout(3,1)); JRadioButton Rbutton1 = new JRadioButton("Credit Card"); JRadioButton Rbutton2 = new JRadioButton("E-Funds"); JRadioButton Rbutton3 = new JRadioButton("Check"); Rbutton3.setSelected(true); ButtonGroup Bgroup = new ButtonGroup(); Bgroup.add(Rbutton1); Bgroup.add(Rbutton2); Bgroup.add(Rbutton3); radioPanel.add(Rbutton1); radioPanel.add(Rbutton2); radioPanel.add(Rbutton3); radioPanel.setBounds(10,50,50,40); //this is where I'm trying to position the panel with the radio buttons paymentPanel.add(radioPanel); contentPane.add(paymentPanel); //contentPane is the frame contentPane.setVisible(true);

  • How to set default values to all wrong or null parameters of method?

    - by Roman
    At the moment I have this code (and I don't like it): private RenderedImage private RenderedImage getChartImage (GanttChartModel model, String title, Integer width, Integer height, String xAxisLabel, String yAxisLabel, Boolean showLegend) { if (title == null) { title = ""; } if (xAxisLabel == null) { xAxisLabel = ""; } if (yAxisLabel == null) { yAxisLabel = ""; } if (showLegend == null) { showLegend = true; } if (width == null) { width = DEFAULT_WIDTH; } if (height == null) { height = DEFAULT_HEIGHT; } ... } How can I improve it? I have some thoughts about introducing an object which will contain all these parameters as fields and then, maybe, it'll be possible to apply builder pattern. But still don't have clear vision how to implement that and I'm not sure that it's worth to be done. Any other ideas?

  • Set Caret position with JTextArea in JScrollPane

    - by Albinoswordfish
    Right now I have a JTextArea inside of a JScrollPane. For the current content it has both a vertical and horizontal scroll bar showing up. I'm trying to implement a search functionality where a user can search for a certain string and it will set the caret position to the first occurrence of that string. However it seems that JScrollPane only scrolls vertically when I set my caret position. So matching strings going off the JTextArea horizontally will completely get missed and the horizontal scroll bar won't scroll at all. I'm using the basic function setCaretPosition() for the JTextArea Does anybody have any idea why my JScrollPane isn't moving horizontally using setCaretPosition() Edit: It appears the horizontal scroll bar is scrolling but it moves so little that it's barely noticeable. I can only see the very first pixel of the character. Is there a way to have the scrollbar center (or as much as possible) to the caret position?

  • Androids ExpandableListView - where to put the button listener for buttons that are children

    - by CommonKnowledge
    I have been playing around a lot with the ExpandableListView and I cannot figure out where to add the button listeners for the button that will be the children in the view. I did manage to get a button listener working that uses getChildView() below, but it seems to be the same listener for all the buttons. The best case scenario is that I would be able to implement the button listeners in the class that instantiates the ExpandableListAdapter class, and not have to put the listeners in the actual ExpandableListAdapter class. At this point I don't even know if that is possible I have been experimenting with this tutorial/code: HERE getChildView() @Override public View getChildView(int set_new, int child_position, boolean view, View view1, ViewGroup view_group1) { ChildHolder childHolder; if (view1 == null) { view1 = LayoutInflater.from(info_context).inflate(R.layout.list_group_item_lv, null); childHolder = new ChildHolder(); childHolder.section_btn = (Button)view1.findViewById(R.id.item_title); view1.setTag(childHolder); childHolder.section_btn.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Toast.makeText(info_context, "button pushed", Toast.LENGTH_SHORT).show(); } }); }else { childHolder = (ChildHolder) view1.getTag(); } childHolder.section_btn.setText(children_collection.get(set_new).GroupItemCollection.get(child_position).section); Typeface tf = Typeface.createFromAsset(info_context.getAssets(), "fonts/AGENCYR.TTF"); childHolder.section_btn.setTypeface(tf); return view1; } Any help would be much appreciated. Thank you and I will be standing by.

  • Netbeans GUI editor problems

    - by RenegadeAndy
    Hey guys. Im making a portion of my app using the netbeans gui editor. Great so far. However ive added a new checkbox - and when i load the panel in my app the text attribute isnt shown...its just blank as if i have no caption on it... all the other ones display - so this is very annoying. It kind of seems that I have hit the limit on gui items or something, becasue any new items I add I cannot seem then, If i add new labels they dont show either :S! The other problems Im having are that the size of the window im editting appears to be fixed - every time i change it, it jumps back to the same size - how do i stop this from happening? Cheers Andy

  • How to Deploy my Open Source Projects using Maven's Central Repository?

    - by sfussenegger
    Is there anything I could do to get my own open source stuff into Maven's Central repository? I've wondered many times how I could get my own projects into Maven's Central repository. I was asking this myself, especially as I've seen some well known projects hosting their own repository, requiring users to add dependency and repository. At the same time, it's getting difficult for other projects to depend on those projects. As I neither want others to add an additional repository nor to host one myself, I'm looking for other ways. And why aren't some projects using the option to deploy to Maven Central in favor of their self-hosted repository? Any good reasons that aren't obvious?

  • How can I store large amount of data from a database to XML (memory problem)?

    - by Andrija
    First, I had a problem with getting the data from the Database, it took too much memory and failed. I've set -Xmx1500M and I'm using scrolling ResultSet so that was taken care of. Now I need to make an XML from the data, but I can't put it in one file. At the moment, I'm doing it like this: while(rs.next()){ i++; xmlStringBuilder.append("\n\t<row>"); xmlStringBuilder.append("\n\t\t<ID>" + Util.transformToHTML(rs.getInt("id")) + "</ID>"); xmlStringBuilder.append("\n\t\t<JED_ID>" + Util.transformToHTML(rs.getInt("jed_id")) + "</JED_ID>"); xmlStringBuilder.append("\n\t\t<IME_PJ>" + Util.transformToHTML(rs.getString("ime_pj")) + "</IME_PJ>"); //etc. xmlStringBuilder.append("\n\t</row>"); if (i%100000 == 0){ //stores the data to a file with the name i.xml storeKBR(xmlStringBuilder.toString(),i); xmlStringBuilder= null; xmlStringBuilder= new StringBuilder(); } and it works; I get 12 100 MB files. Now, what I'd like to do is to do is have all that data in one file (which I then compress) but if just remove the if part, I go out of memory. I thought about trying to write to a file, closing it, then opening, but that wouldn't get me much since I'd have to load the file to memory when I open it. P.S. If there's a better way to release the Builder, do let me know :)

  • How to find longest common substring using trees?

    - by user384706
    The longest common substring problem according to wiki can be solved using a suffix tree. From wiki: The longest common substrings of a set of strings can be found by building a generalised suffix tree for the strings, and then finding the deepest internal nodes which have leaf nodes from all the strings in the subtree below it I don't get this. Example: if I have: ABCDE and XABCZ then the suffix tree is (some branches from XABCZ omitted due to space): The longest common substring is ABC but it is not I can not see how the description of wiki helps here. ABC is not the deepest internal nodes with leaf nodes. Any help to understand how this works?

  • Kerning problems when drawing text character by character

    - by shekel
    I'm trying to draw strings character by character to add lighting effects to shapes composed of text. while (i != line.length()) { c = line.substring(i, i + 1); cWidth = g.getFontMetrics().stringWidth(c); g.drawString(c, xx += cWidth, yy); i++; } The problem is, the width of a character isn't the actual distance it's drawn from another character when those two characters are printed as a string. Is there any way to get the correct distance in graphics2d?

  • How can I load a property lazily in JDO (on Google App Engine)?

    - by luciano
    I have this code in one of my @PersistenceCapable classes: @Persistent private Blob data; The Blob can be quite big, so I'd like to load it lazily since most of the times I don't need it. How can I annotate that property to avoid immediate loading? I could create another class that contains the Blob alone and then use a lazy one-to-one, but I'd like to solve this with annotations.

  • Headless build of eclipse features - PDE Tools or Buckminster?

    - by Max
    I am trying to set up a headless build for a big eclipse feature, containing other features and plugins. As some needed plugins are generated using GMF and EMF, the build workflow must be something like this: SVN Check-out Invoke Generation Run Tests Build all Publish update-site Over the last couple of weeks, i played around with PDE Headless Build and Buckminster. Anyhow i still got problems with both and can't decide on which i should spent my effort. So what would you prefer? What experience you made? Anybody out there who needed to set up a similiar workflow before? Thank you for all answers :)

  • Can I assign a maven dependency to a specific repo?

    - by mds
    So I have several large projects that use up to 8 different external repos, all specified in settings.xml rather than in poms. A lot of our internal dependencies are snapshots, so this obviously causes a lot of checking for updates across several external repos, when they are all in our internal repo. So my question is, is there a way to setup a profile/filter or anything similar where I can ensure that an update will only be checked for in a specific repo(s)? This is all in the spirit of better/quicker builds. Thanks!

  • log4j relative file path

    - by Bob
    Hi, I'd like my web app to log into files with this path: webapp/logs/ I can set the absolute path in the log4j.properties file, but the production environment's directory structure will be different. Is there any way I could do it? Here is how I do: log4j.appender.f=org.apache.log4j.RollingFileAppender log4j.appender.f.layout=org.apache.log4j.PatternLayout log4j.appender.f.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n log4j.appender.f.File=log.out log4j.appender.f.MaxFileSize=100KB This is printing logs into a file named log.log in my eclipse directory (c://eclipse). I'm using Tomcat 6.
