  • JAXB - representing an element as a boolean member?

    - by Marcus
    We have this XML: <Summary> <ValueA>xxx</ValueA> <ValueB/> </Summary> <ValueB/> will never have any attributes or inner elements. It's a boolean type element - it exists (true) or it doesn't (false). JAXB generated a Summary class with a String valueA member, which is good. But for ValueB, JAXB generated a ValueB inner class and a corresponding member: @XmlElement(name = "ValueB") protected Summary.ValueB valueB; But what I'd like is a boolean member and no inner class: @XmlElement(name = "ValueB") protected boolean valueB; How can you do this? I'm not looking to regenerate the classes, I'd like to just make the code change manually.

  • Why does Event intent in android not return a result?

    - by dhaval
    I am creating a event using Intent intent = new Intent(Intent.ACTION_EDIT); intent.setType("vnd.android.cursor.item/event"); And invoking the intent using startActivityForResult(intent, Constants.LINK_CALENDER); There is nothing returned to call in onActivityResult(int requestCode, int resultCode, Intent data) It always returns data=null ie., returned intent result is always null. I am trying to retrieve the "Done/Revert" state of calender event just created and some identity so that i can open the event again in future from elsewhere in code.

  • JUnit - stop it from exiting on finish?

    - by waitinforatrain
    Hi guys, Quick JUnit question. I'm running some unit tests that involve starting up the GUI and doing a load of stuff. I would like to see the results after the test to confirm it visually. However, it gets to the end of the code and exits, as it should. If I want to override this, I put a breakpoint on the last line of the test. This is pretty awkward though. Is there some option to stop it from exiting?

  • JSF: how to update the list after delete an item of that list

    - by Harry Pham
    It will take a moment for me to explain this, so please stay with me. I have table COMMENT that has OneToMany relationship with itself. @Entity public class Comment(){ ... @ManyToOne(optional=true, fetch=FetchType.LAZY) @JoinColumn(name="REPLYTO_ID") private Comment replyTo; @OneToMany(mappedBy="replyTo", cascade=CascadeType.ALL) private List<Comment> replies = new ArrayList<Comment>(); public void addReply(NewsFeed reply){ replies.add(reply); reply.setReplyTo(this); } public void removeReply(NewsFeed reply){ replies.remove(reply); } } So you can think like this. Each comment can have a List of replies which are also type Comment. Now it is very easy for me to delete the original comment and get the updated list back. All I need to do after delete is this. allComments = myEJB.getAllComments(); //This will query the db and return updated list But I am having problem when trying to delete replies and getting the updated list back. So here is how I delete the replies. Inside my managed bean I have //Before invoke this method, I have the value of originalFeed, and deletedFeed set. //These original comments are display inside a p:dataTable X, and the replies are //displayed inside p:dataTable Y which is inside X. So when I click the delete button //I know which comment I want to delete, and if it is the replies, I will know //which one is its original post public void deleteFeed(){ if(this.deletedFeed != null){ scholarEJB.deleteFeeds(this.deletedFeed); if(this.originalFeed != null){ //Since the originalFeed is not null, this is the `replies` //that I want to delete scholarEJB.removeReply(this.originalFeed, this.deletedFeed); } feeds = scholarEJB.findAllFeed(); } } Then inside my EJB scholarEJB, I have public void removeReply(NewsFeed comment, NewsFeed reply){ comment = em.merge(comment); comment.removeReply(reply); em.persist(comment); } public void deleteFeeds(NewsFeed e){ e = em.find(NewsFeed.class, e.getId()); em.remove(e); } When I get out, the entity (the reply) get correctly removed from the database, but inside the feeds List, reference of that reply still there. It only until I log out and log back in that the reply disappear. Please help

  • Eclipse antRunner command line build has wrong dependency build order

    - by Sam Jones
    My team's Eclipse RCP app builds fine from the Eclipse IDE. When I try to build it from the command line, using the antRunner application, it builds the plugins out of order -- a plugin builds before it's dependencies are built, and so can't resolve some of the needed classes. Where should I look to fix this? As far as I can tell, the dependencies are set up correctly (a feature that depends on a plugin that depends on another plugin). I have my build.properties and folder structure set up as specified here. Is there anything else I should look at?

  • How to programmatically call a Maven-task

    - by pmf
    I'm using Maven in the context of another build-tool (leiningen for Clojure, but this should not matter), and I would like to know how I would call a plugin like dependency:build-classpath programmatically (i.e. via the Maven-API, not via the mvn-command).

  • Google app engine - what is the lifecycle of PersistenceManager?

    - by Domchi
    What is the preferred way of using GAE datastore PersistenceManager for web app? GAE instructions are a bit ambiguous on the matter. Do I instantiate PersistenceManagerFactory for each RPC call, or do I use only one factory for all requests? Do I call PMF.get().getPersistenceManager(), or do I call PMF.get().getPersistenceManagerProxy()? Do I close PM after each RPC call, or do I leave it open? What are you guys doing? Furthermore, I'm not certain how GAE handles 30-second-per-request limit. Is it even possible to reference the same PM between requests?

  • Getting hibernate to log clob parameters

    - by SCdF
    (see here for the problem I'm trying to solve) How do you get hibernate to log clob values it's going to insert. It is logging other value types, such as Integer etc. I have the following in my log4j config: log4j.logger.net.sf.hibernate.SQL=DEBUG log4j.logger.org.hibernate.SQL=DEBUG log4j.logger.net.sf.hibernate.type=DEBUG log4j.logger.org.hibernate.type=DEBUG Which produces output such as: (org.hibernate.SQL) insert into NoteSubstitutions (note, listIndex, substitution) values (?, ?, ?) (org.hibernate.type.LongType) binding '170650' to parameter: 1 (org.hibernate.type.IntegerType) binding '0' to parameter: 2 (org.hibernate.SQL) insert into NoteSubstitutions (note, listIndex, substitution) values (?, ?, ?) (org.hibernate.type.LongType) binding '170650' to parameter: 1 (org.hibernate.type.IntegerType) binding '1' to parameter: 2 However you'll note that it never displays parameter: 3 which is our clob. What I would really want is something like: (org.hibernate.SQL) insert into NoteSubstitutions (note, listIndex, substitution) values (?, ?, ?) (org.hibernate.type.LongType) binding '170650' to parameter: 1 (org.hibernate.type.IntegerType) binding '0' to parameter: 2 (org.hibernate.type.ClobType) binding 'something' to parameter: 3 (org.hibernate.SQL) insert into NoteSubstitutions (note, listIndex, substitution) values (?, ?, ?) (org.hibernate.type.LongType) binding '170650' to parameter: 1 (org.hibernate.type.IntegerType) binding '1' to parameter: 2 (org.hibernate.type.ClobType) binding 'something else' to parameter: 3 How do I get it to show this in the log?

  • jdbc query - date ranges as parameters

    - by pstanton
    Hi all, I'd like to write a single JDBC statement that can handle the equivalent of any number of NOT BETWEEN date1 AND date2 where clauses. By single query, i mean that the same SQL string will be used to create the JDBC statements and then have different parameters supplied. This is so that the underlying frameworks can efficiently cache the query (i've been stung by that before). Essentially, I'd like to find a query that is the equivalent of SELECT * FROM table WHERE mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? and at the same time could be used with fewer parameters: SELECT * FROM table WHERE mydate NOT BETWEEN ? AND ? or more parameters SELECT * FROM table WHERE mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? I will consider using a temporary table if that will be simpler and more efficient. thanks for the help!

  • How to get equivalent of ResultSetMetaData without ResultSet

    - by javanix
    Hey Guys - I need to resolve a bunch of column names to column indexes (so as to use some of the nice ResultSetMetaData methods). However, the only way that I know how to get a ResultSetMetaData object is by calling getMetaData() on some ResultSet. The problem I have with that is that grabbing a ResultSet takes up uneccesary resources in my mind - I don't really need to query the data in the table, I just want some information about the table. Does anyone know of any way to get a RSMD object without getting a ResultSet (from a potentially huge table) first? Thanks!

    - by Milad.KH
    Hi I have two classes which have a Unidirectional One to Many relation with each other. public class Offer{ ... @OneToMany(cascade=CascadeType.ALL) @JoinTable(name = "Offer_Fields", joinColumns = @JoinColumn(name = "OFFER_ID"), inverseJoinColumns = @JoinColumn(name = "FIELDMAPPER_ID")) private Set<FieldMapper> fields = new HashSet<FieldMapper>(); } public class FieldMapper{ ... } I want to store an Offer with a set of FieldMapper to database. When I Use CascadeType.ALL in my OneToMany, I got this error: org.hibernate.HibernateException: Illegal attempt to associate a collection with two open sessions and when I change CascadeType to something else I got this error: org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: com.RCSTT.library.FieldMapper Thanks for your help.

  • JPA is not good enough

    - by Cristiano Sanchez
    Working in a medium size project during last 4 months - we are using JPA and Spring - I'm quite sure that JPA is not powerfull for projects that requires more than CRUD screen... Query interface is poor, Hibernate doesn't respect JPA spec all the time and lot of times I need to use hibernate classes, annotations and config. What do you guys think about JPA? Is it not good enough?

  • Printing is not working in tomcat, when i start server with services.msc(From client side we could not print )

    - by maya
    I am using JasperReports 1.3.1 to print the report. I am sing eclipse and tomcat for development purpose. In eclipse, when i run the application, the below code will show the listed printer devices and print button. If i click the print button, the report is printing by selected device. PrintRequestAttributeSet printRequestAttributeSet = new HashPrintRequestAttributeSet(); printRequestAttributeSet.add(MediaSizeName.ISO_A5); PrintServiceAttributeSet printServiceAttributeSet = new HashPrintServiceAttributeSet(); JRPrintServiceExporter exporter = new JRPrintServiceExporter(); exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint); exporter.setParameter(JRPrintServiceExporterParameter.PRINT_REQUEST_ATTRIBUTE_SET, printRequestAttributeSet); exporter.setParameter(JRPrintServiceExporterParameter.PRINT_SERVICE_ATTRIBUTE_SET, printServiceAttributeSet); exporter.setParameter(JRPrintServiceExporterParameter.DISPLAY_PAGE_DIALOG, Boolean.FALSE); exporter.setParameter(JRPrintServiceExporterParameter.DISPLAY_PRINT_DIALOG, Boolean.TRUE); exporter.exportReport(); Here I am passing jasperPrint as a parameter which i manually construted.Its working good My problem is: I created war file and pasted in tomcat Apache Software Foundation\Tomcat 6.0\webapps directory and started the tomcat by using services.msc. At this point, its not displaying the listed printer details and also not printing. I put some logger, I found that, the code is hanging with exporter.exportReport(); after this line code is not executing . Please suggest me for how to print from client side using jasper

  • How to use SQLErrorCodeSQLExceptionTranslator and DAO class with @Repository in Spring?

    - by GuidoMB
    I'm using Spring 3.0.2 and I have a class called MovieDAO that uses JDBC to handle the db. I have set the @Repository annotations and I want to convert the SQLException to the Spring's DataAccessException I have the following example: @Repository public class JDBCCommentDAO implements CommentDAO { static JDBCCommentDAO instance; ConnectionManager connectionManager; private JDBCCommentDAO() { connectionManager = new ConnectionManager("org.postgresql.Driver", "postgres", "postgres"); } static public synchronized JDBCCommentDAO getInstance() { if (instance == null) instance = new JDBCCommentDAO(); return instance; } @Override public Collection<Comment> getComments(User user) throws DAOException { Collection<Comment> comments = new ArrayList<Comment>(); try { String query = "SELECT * FROM Comments WHERE Comments.userId = ?"; Connection conn = connectionManager.getConnection(); PreparedStatement stmt = conn.prepareStatement(query); stmt = conn.prepareStatement(query); stmt.setInt(1, user.getId()); ResultSet result = stmt.executeQuery(); while (result.next()) { Movie movie = JDBCMovieDAO.getInstance().getLightMovie(result.getInt("movie")); comments.add(new Comment(result.getString("text"), result.getInt("score"), user, result.getDate("date"), movie)); } connectionManager.closeConnection(conn); } catch (SQLException e) { e.printStackTrace(); //CONVERT TO DATAACCESSEXCEPTION } return comments; } } I Don't know how to get the Translator and I don't want to extends any Spring class, because that is why I'm using the @Repository annotation

  • Is it possible to use objects as function paremeters in EL with JBoss EL resolver?

    - by calavera.info
    There is this sentence in JBoss EL resolver online documentation: It's important to fully understand how this extension to EL works. When the page is rendered, the parameter names are stored (for example, hotel.id and user.username), and evaluated (as value expressions) when the page is submitted. You can't pass objects as parameters! But I had used objects as function parameters in my project before I accidentally read this hint and it worked! How is it possible? I'm afraid of that there is some magic now...

  • Why does the BigFraction class in the Apache-Commons-Math library return incorrect division results?

    - by Timothy Lee Russell
    In the spirit of using existing, tested and stable libraries of code, I started using the Apache-Commons-Math library and its BigFraction class to perform some rational calculations for an Android app I'm writing called RationalCalc. It works great for every task that I have thrown at it, except for one nagging problem. When dividing certain BigFraction values, I am getting incorrect results. If I create a BigFraction with the inverse of the divisor and multiply instead, I get the same incorrect answer but perhaps that is what the library is doing internally anyway. Does anyone know what I am doing wrong? The division works correctly with a BigFraction of 2.5 but not 2.51, 2.49, etc... // *** incorrect! *** BigFraction one = new BigFraction(1.524); //one: 1715871458028159 / 1125899906842624 BigFraction two = new BigFraction(2.51); //two: 1413004383087493 / 562949953421312 BigFraction three = one.divide(two); //three: 0 Log.i("solve", three.toString()); //should be 0.607171315 ?? //returns 0 // *** correct! **** BigFraction four = new BigFraction(1.524); //four: 1715871458028159 / 1125899906842624 BigFraction five = new BigFraction(2.5); //five: 5 / 2 BigFraction six = four.divide(five); //six: 1715871458028159 / 2814749767106560 Log.i("solve", six.toString()); //should be 0.6096 ?? //returns 0.6096

  • how to detect an IMAPMessage is not an email but a Task or Calendar item

    - by raticulin
    I am accessing Lotus and Groupwise using javamail via IMAP, recursively accessing all folders and processing email I find. But in folders like Tasklist and Calendar (those are from Groupwise but I think I remember Lotus had similar things), I get the items in there as instances of IMAPMessage, and so they are processed as if they were mail. I understand those items get exposed as mail through the IMAP protocol (either by design or by mistake), but I only want to process proper mail. Is there a way to do this? I have dismissed following approaches so far: Make sure the message has a message-id, at least in Groupwise Calendar items have it. Ignore folders by name (such as Calendar and Tasklist): is not totally correct as a user can move mail inside those folders. What I am looking is some IMAP api call I have missed so far or something in those lines...

  • Colouring JTree's TreeNodes

    - by Amadan
    I have a JTree which I give objects that implement the TreeNode interface, and a custom TreeModel to display them (not using DefaultMutableTreeNode). I would like to change the text colour of some nodes. I can't find anything in the docs, except javax.swing.tree.DefaultTreeCellRenderer.setTextNonSelectionColor(Color newColor), but it will change everything indiscriminately, and I only need it for some nodes (specifically, broken links, i.e. nodes whose corresponding files can't be found on the disk, should be greyed out, the rest should be default). Can it be done, and how?
