  • How to update maven repository in eclipse?

    - by Stephane Grenier
    Assuming you're already using the m2eclipse plugin, what can you do it doesn't update the dependencies to the latest in your repo. For example, on the command line you can just add the -U flag as in: mvn clean install -U to force the dependencies to be updated. Is there something like this within eclipse since it doesn't always seem to pick up the latest updates.

  • Exercise 26 of The Pragmatic Programmer

    - by _ande_turner_
    There is a code snippet presented in The Pragmatic Programmer on page 143 as: public class Colada { private Blender myBlender; private Vector myStuff; public Colada() { myBlender = new Blender(); myStuff = new Vector(); } private doSomething() { myBlender.addIngredients(myStuff.elements()); } } This obeys the Law of Demeter / Principle of Least Knowledge. Is it preferable to, and are there any caveats for, replacing it with the following, which utilises Dependency Injection? public class Colada throws IllegalArgumentException { private Blender myBlender; private Vector myStuff; public Colada(Blender blender, Vector stuff) { blender == null ? throw new IllegalArgumentException() : myBlender = blender; stuff == null ? throw new IllegalArgumentException() : myStuff = stuff; } public getInstance() { Blender blender = new Blender(); Vector stuff = new Vector(); return new Colada(blender, stuff); } private doSomething() { myBlender.addIngredients(myStuff.elements()); } }

  • PriorityQueue update problems

    - by Bharat
    After going through a bunch of questions here on SO, I still have no idea what exactly is going wrong with my code and would appreciate some help. I'm trying to implement a priority queue based on f-costs for an A* algorithm, and while the algorithm works fine for short pathfinding distances, it seems to go wrong when there's an obstacle or when the distance between start and goal points is greater than about 30 squares (although sometimes it screws up for less too). while(!m_qOpenList.isEmpty()) { m_xCurrent=m_qOpenList.poll(); m_xCurrent.setBackground(Color.red); m_qClosedList.add(m_xCurrent); if(m_xCurrent.getStatus()==2) { System.out.println("Target Reached"); solved=true; break; } iX=m_xCurrent.getXCo(); iY=m_xCurrent.getYCo(); for(i=iX-1;i<=iX+1;i++) for(j=iY-1;j<=iY+1;j++) { if(i<0||j<0||i>m_iMazeX||j>m_iMazeX||(i==iX&&j==iY) || m_xNode[i][j].getStatus()==4|| m_qClosedList.contains(m_xNode[i][j])) continue; m_xNode[i][j].score(m_xCurrent,m_xGoal); m_qOpenList.add(m_xNode[i][j]); } } It's quite rudimentary as I'm just trying to get it to work for now. m_qOpenList is the PriorityQueue. The problem is that when I debug the program, at some point (near an obstacle), a Node with a fcost of say 84 has higher priority than a node with an fcost of 70. I am not attempting to modify the values once they're on the priority queue. You'll notice that I add at the end of the while loop (I read somewhere that the priorityqueue reorders itself when stuff is added to it), and poll right after that at the beginning. Status of 2 means the Node is the goal, and a status of 4 means that it is unwalkable. public int compareTo(Node o) { if(m_iF<o.m_iF) return -1; if(m_iF>o.m_iF) return 1; return 0; } And that's the compareTo function. Can you see a problem? =(

  • Web Apps: Closeable Announcements/Info/Tooltip boxes (how to implement)

    - by Daxon
    I want to understand how to implement an announcement/info box system that displays a box for the user with information. The user can do nothing or close the box, but then it will never be seen again. E.g. Facebook home page. Box asking for Translators. if you leave it then its always there. But if you close it, it never appears again. Does this mean that a Boolean value needs to be used and checked for announcement/info boxes? I'm looking for a pseudo way with database tables to do this?

  • Blackberry Eclispe plugin and emulator

    - by gmcalab
    So I installed the following installation packages to develop Blackberry apps using the included emulators. I first installed them on a macbook pro, virtualizing windows 7 x86 with vmware. Everything worked fine, I created a quick HelloWorld app and it compiled and fully ran in the emulator. I did no other configuration. So I went to install this on my desktop PC with Windows 7 x64. I installed the exact same items. When I choose to run with the Blackberry Emulator, nothing happens. Any ideas? Here's the file list: BlackBerry_JDE_PluginFull_1.0.0.67 (This includes Eclispe) jdk-6u18-windows-i586

  • Why does my Sax Parser produce no results after using InputStream Read?

    - by Andy Barlow
    Hello, I have this piece of code which I'm hoping will be able to tell me how much data I have downloaded (and soon put it in a progress bar), and then parse the results through my Sax Parser. If I comment out basically everything above the //xr.parse(new InputSource(request.getInputStream())); line and swap the xr.parse's over, it works fine. But at the moment, my Sax parser tells me I have nothing. Is it something to do with is.read (buffer) section? Also, just as a note, request is a HttpURLConnection with various signatures. /*Input stream to read from our connection*/ InputStream is = request.getInputStream(); /*we make a 2 Kb buffer to accelerate the download, instead of reading the file a byte at once*/ byte [ ] buffer = new byte [ 2048 ] ; /*How many bytes do we have already downloaded*/ int totBytes,bytes,sumBytes = 0; totBytes = request.getContentLength () ; while ( true ) { /*How many bytes we got*/ bytes = is.read (buffer); /*If no more byte, we're done with the download*/ if ( bytes <= 0 ) break; sumBytes+= bytes; Log.v("XML", sumBytes + " of " + totBytes + " " + ( ( float ) sumBytes/ ( float ) totBytes ) *100 + "% done" ); } /* Parse the xml-data from our URL. */ // OLD, and works if comment all the above //xr.parse(new InputSource(request.getInputStream())); xr.parse(new InputSource(is)) /* Parsing has finished. */; Can anyone help me at all?? Kind regards, Andy

  • Using an array as parameter to a class.

    - by Gabriel A. Zorrilla
    I have created an array Man: public main blah blah{ man = man[10]; } Man has fields such as Man.name; Man.age; ... In Man class, there is a OnClick method that opens a new window showing its name and age. public Man(){ Onclick(){ InfoWindow showinfo = new InfoWindow(this.getid()) // If this is Man[2] the id would be 2. } And in InfoWindow class: public class InfoWindow extends JFrame{ public InfoWindow(Man selectedMan){ setSize(300, 200); JLabel info = new JLabel(selectedMan.getname()); add(info); info.setVisible(true); } } Basically, that's wanna acomplish (show in pseudocode), pass a Man[i] into a class that when a window is created, shows the info related to that man. This is how i'm actualy trying to implement it but it's not working, i'm pretty sure there is a misconception from me in some part. Any help?

  • Is this a good approach to address double-base64-encoding?

    - by Freiheit
    My software understands attachments, like PNGs attached to user records. These attachments are usually sent in from outside sources as a Base64 encoded string. The database stores whatever data it is given, Base64 encoded or not. When I serve up the attachment for download I do this: if (Base64.isBase64(data)) { data = Base64.decodeBase64(data); } There is a potential for data that is double encoded. For instance the sender of a message had base64 encoded data, then encoded it again when building the message to send to me. I think the following code would address that circumstance: while (Base64.isBase64(data)) { data = Base64.decodeBase64(data); } So if data is encoded multiple times, it would be decoded until its in its 'raw' state and then served up for download. Is this approach an acceptable way to address that problem? Ideally some sort of checking could happen at the edge when I receive attachment data, but that will take more time. This looping seems to be a faster way to do it. The 'Base64' library is Apache Commons: http://commons.apache.org/codec/apidocs/org/apache/commons/codec/binary/Base64.html I trust it to properly identify Base64 encoded data.

  • JAX-WS and JPA, how to load stub objects using JPA?

    - by opensas
    I'm trying to develope a soap web service that has to access a mysql db. I have to replicate an existing service, so I created all the stub object from it's wsdl file Netbeans created all the necessary stuff for me (new, web service from wsdl), it works ok... Now I'm trying to use JPA to load all those objects from the database. So far I was going fine, I created the classes using (new, entity class from database), and then copied all the annotations to the classes generated by wsimport, and it was working fine. The problem is that netbeans insists on running wsimport again, and then I loose all my annotations... Is there some way to tell netbeans not to regenerate those files? I think this situation shoulb be pretty common, I mean developing a web service from a wsdl and then having to fill those objects with data using JPA. what would be the correct aproach to this kind of situation? thanks a lot saludos sas I've also tried inheriting from the stubs, and addign there the persistence annotations, but I had troubles with overlaping members, I'm redeclaring protected properties...

  • How to get descriptive error messages from DB2?

    - by tangens
    When I call a SQL statement via JDBC on the DB2 and the statement fails, I catch an SQLException with the following message text: com.ibm.db2.jcc.a.nn: DB2 SQL Error: SQLCODE=-206, SQLSTATE=42703, SQLERRMC=O.METADATENSATZ, DRIVER=3.52.95 I tried an automatic translation of the message according to the error list published by IBM, but there are placeholders inside the messages referencing other elements of the exception. While looking for these elements inside the exception, I found the DB2ExceptionFormatter and tried to use it to access the missing elements. But here I stopped, because the DB2ExceptionFormatter gave me a clue: Error occurred while trying to obtain message text from server. Only message tokens are available. So my question is: What do I have to configure to get the correct messages from the DB2 server? If I can get a human readable message from the server, I could use it directly and wouldn't have to translate it by myself.

  • Joda-Time: DateTime, DateMidnight and LocalDate usage

    - by fraido
    Joda-Time library includes different datetime classes DateTime - Immutable replacement for JDK Calendar DateMidnight - Immutable class representing a date where the time is forced to midnight LocalDateTime - Immutable class representing a local date and time (no time zone) I'm wondering how are you using these classes in your Layered Applications. I see advantages in having almost all the Interfaces using LocalDateTime (at the Service Layer at least) so that my Application doesn't have to manage Timezones and can safely assume Times always in UTC. My app could then use DateTime to manage Timezones at the very beginning of the Execution's Flow. I'm also wondering in which scenario can DateMidnight be useful.

  • question about joGL (glTexImage2D)

    - by Nour
    Hi everybody I was trying to load a texture using joGL library but it seems that something is missing when using this method glTexImage2D at : IOStream wdis = new IOStream(fileName); wdis.skipBytes(18); int width = wdis.readIntW(); // dis.skipBytes(2); int height = wdis.readIntW(); // dis.skipBytes(2); wdis.skipBytes(28); byte buf[] = new byte[wdis.available()]; wdis.read(buf); wdis.close(); gl.glBindTexture(GL.GL_TEXTURE_2D, BMPtextures[index]); gl.glTexImage2D(GL.GL_TEXTURE_2D, 0, 3, width, height, 0, GL.GL_BGR, GL.GL_UNSIGNED_BYTE, buf); gl.glTexParameteri(GL.GL_TEXTURE_2D, GL.GL_TEXTURE_MAG_FILTER, GL.GL_LINEAR); gl.glTexParameteri(GL.GL_TEXTURE_2D, GL.GL_TEXTURE_MIN_FILTER, GL.GL_LINEAR); as IOStream is a class that extends DataInputStream it shows a message that glTexImage2D(int,int,int,int,int,int,int,int,byte[]) is not found at javax.media.opengl.GL I couldn't figure the problem her because it's an open source code and it seems to work perfectly with my friends but unfortunately not with me even though we are using the same library and the same JDK version what shall I do ??

  • Recursion causes exit to exit all JFrames (terminates app)

    - by Trizicus
    I have made an application that gives the user the option to open up a new spawn of the application entirely. When the user does so and closes the application the entire application terminates; not just the window. How should I go about recursively spawning an application and then when the user exits the JFrame spawn; killing just that JFrame and not the entire instance? Here is the relevant code: [...] JMenuItem newMenuItem = new JMenuItem ("New"); newMenuItem.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { new MainWindow(); } }); fileMenu.add(newMenuItem); [....] JMenuItem exit = new JMenuItem("Exit"); exit.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } }); fileMenu.add(exit); [...]

  • JAXB: How to avoid repeated namespace definition for xmlns:xsi

    - by sfussenegger
    I have a JAXB setup where I use a @XmlJavaTypeAdapter to replace objects of type Person with objects of type PersonRef that only contains the person's UUID. This works perfectly fine. However, the generated XML redeclares the same namespace (xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance") every time it's used. While this is generally okay, it just doesn't feel right. How can I configure JAXB to declare xmlns:xsi at the very beginning of the document? Can I manually add namespace declarations to the root element? Here's an example of what I want to achive: Current: <person uuid="6ec0cf24-e880-431b-ada0-a5835e2a565a"> <relation type="CHILD"> <to xsi:type="personRef" uuid="56a930c0-5499-467f-8263-c2a9f9ecc5a0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/> </relation> <relation type="CHILD"> <to xsi:type="personRef" uuid="6ec0cf24-e880-431b-ada0-a5835e2a565a" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/> </relation> <!-- SNIP: some more relations --> </person> Wanted: <person uuid="6ec0cf24-e880-431b-ada0-a5835e2a565a" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <relation type="CHILD"> <to xsi:type="personRef" uuid="56a930c0-5499-467f-8263-c2a9f9ecc5a0"/> </relation> <relation type="CHILD"> <to xsi:type="personRef" uuid="6ec0cf24-e880-431b-ada0-a5835e2a565a"/> </relation> <!-- SNIP: some more relations --> </person>

  • SSL Certificate without host name in it

    - by Sinuhe
    I have implemented a web service with server and client authentication using keytool. The problem is that this authentication doesn't work if I don't include the name of the host in it. For example: keytool -genkey -alias myAlias -keyalg RSA -keypass myPassword -storepass myPassword -keystore my.keystore -dname "CN=myhost" But I don't need and I don't like validation by host or by IP. Is there any way of avoiding it? Thanks.

  • How to implement login page using Spring Security so that it works with Spring web flow?

    - by simon
    I have a web application using Spring 2.5.6 and Spring Security 2.0.4. I have implemented a working login page, which authenticates the user against a web service. The authentication is done by defining a custom authentincation manager, like this: <beans:bean id="customizedFormLoginFilter" class="org.springframework.security.ui.webapp.AuthenticationProcessingFilter"> <custom-filter position="AUTHENTICATION_PROCESSING_FILTER" /> <beans:property name="defaultTargetUrl" value="/index.do" /> <beans:property name="authenticationFailureUrl" value="/login.do?error=true" /> <beans:property name="authenticationManager" ref="customAuthenticationManager" /> <beans:property name="allowSessionCreation" value="true" /> </beans:bean> <beans:bean id="customAuthenticationManager" class="com.sevenp.mobile.samplemgmt.web.security.CustomAuthenticationManager"> <beans:property name="authenticateUrlWs" value="${WS_ENDPOINT_ADDRESS}" /> </beans:bean> The authentication manager class: public class CustomAuthenticationManager implements AuthenticationManager, ApplicationContextAware { @Transactional @Override public Authentication authenticate(Authentication authentication) throws AuthenticationException { //authentication logic return new UsernamePasswordAuthenticationToken(principal, authentication.getCredentials(), grantedAuthorityArray); } The essential part of the login jsp looks like this: <c:url value="/j_spring_security_check" var="formUrlSecurityCheck"/> <form method="post" action="${formUrlSecurityCheck}"> <div id="errorArea" class="errorBox"> <c:if test="${not empty param.error}"> ${sessionScope["SPRING_SECURITY_LAST_EXCEPTION"].message} </c:if> </div> <label for="loginName"> Username: <input style="width:125px;" tabindex="1" id="login" name="j_username" /> </label> <label for="password"> Password: <input style="width:125px;" tabindex="2" id="password" name="j_password" type="password" /> </label> <input type="submit" tabindex="3" name="login" class="formButton" value="Login" /> </form> Now the problem is that the application should use Spring Web Flow. After the application was configured to use Spring Web Flow, the login does not work anymore - the form action to "/j_spring_security_check" results in a blank page without error message. What is the best way to adapt the existing login process so that it works with Spring Web Flow?
