  • One-to-many relationship with JDO in Google App Engine

    - by Marvin
    I've followed the GAE docs on setting up one-to-many relationship in JDO but I'm still having trouble in retrieving the collection data back. I have no problem getting the other non-collection fields back. Here are my classes: @PersistenceCapable public class User{ @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Key key; @Persistent private String uniqueId; @Persistent private String email; @Persistent private List<Address> addresses = new ArrayList<Address>() ; ... } @PersistenceCapable public class Phone{ @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Key key; @Persistent private String number; ... } public class UserDaoImpl implements UserDao { public void insertUser(User user) { if(user.getKey() == null) { com.google.appengine.api.datastore.Key key = KeyFactory.createKey(User.class.getSimpleName(), user.getEmail()); user.setKey(key); } PersistenceManager pm = PersistenceManagerWrapper.getPersistenceManager(); notNull(user); try { pm.makePersistent(user); } finally { pm.close(); } } @SuppressWarnings("unchecked") public User getUser(String uniqueId) { PersistenceManager pm = PersistenceManagerWrapper.getPersistenceManager(); Query query = pm.newQuery(User.class); query.setFilter("uniqueId == uniqueIdParam"); query.declareParameters("String uniqueIdParam"); User user = null; try { List<User> users = (List<User>)(query.execute(uniqueId)); //TODO abstract this if(users.size() > 0) user = users.get(0); } finally { pm.close(); } return user; } } public class UserDaoImplTest { @Test public void getUserTest() { User user = createTestUser(); assertNotNull("The user object should not be null", user); userDao.insertUser(user); User returnedUser = userDao.getUser(TEST_USER_ID); assertNotNull("The returnedUser object should not be null", returnedUser); Assert.assertPropertyEqualsExcludeProperties("User Object", user, returnedUser, ""); } } When I run the test, all the properties for User is populated but the list of Phone if I get is empty.

Sample output follows: java SetDemo Enter string element to be added hello You entered hello Set size is: 10 Set is empty? false Element sixb is member of setA? -1 Set is full? true Element b located on index: 2 Set size is: 9 Elements of setA Member elements on index: 0 hello Member elements on index: 1 world Member elements on index: 2 six Member elements on index: 3 seven Union of setA and setB Member elements on index: 0 b Member elements on index: 1 z Member elements on index: 2 x Member elements on index: 3 y thanks, lupin

  • How do I get the PreviewDialog of Apache FOP to actually display my document?

    - by JRSofty
    Search as I may I have not found a solution to my problem here and I'm hoping the combined minds of StackOverflow will push me in the right direction. My problem is as follows, I'm developing a print and print preview portion of a messaging system's user agent. I was given specific XSLT templates that after transforming XML will produce a Formatting Objects document. With Apache FOP I've been able to render the FO document into PDF which is all fine and good, but I would also like to display it in a print preview dialog. Apache FOP contains such a class called PreviewDialog which requires in its constructor a FOUserAgent, which I can generate, and an object implementing the Renderable Interface. The Renderable Interface has one implementing class in the FOP package which is called InputHandler which takes in its constructor a standard io File object. Now here is where the trouble begins. I'm currently storing the FO document as a temp file and pass this as a File object to an InputHandler instance which is then passed to the PreviewDialog. I see the dialog appear on my screen and along the bottom in a status bar it says that it is generating the document, and that is all it does. Here is the code I'm trying to use. It isn't production code so it's not pretty: import java.io.BufferedOutputStream; import java.io.File; import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.IOException; import java.io.OutputStream; import java.util.Random; import javax.xml.transform.Result; import javax.xml.transform.Source; import javax.xml.transform.Transformer; import javax.xml.transform.TransformerConfigurationException; import javax.xml.transform.TransformerException; import javax.xml.transform.TransformerFactory; import javax.xml.transform.sax.SAXResult; import javax.xml.transform.stream.StreamResult; import javax.xml.transform.stream.StreamSource; import org.apache.fop.apps.FOPException; import org.apache.fop.apps.FOUserAgent; import org.apache.fop.apps.Fop; import org.apache.fop.apps.FopFactory; import org.apache.fop.cli.InputHandler; import org.apache.fop.render.awt.viewer.PreviewDialog; public class PrintPreview { public void showPreview(final File xslt, final File xmlSource) { boolean err = false; OutputStream out = null; Transformer transformer = null; final String tempFileName = this.getTempDir() + this.generateTempFileName(); final String tempFoFile = tempFileName + ".fo"; final String tempPdfFile = tempFileName + ".pdf"; System.out.println(tempFileName); final TransformerFactory transformFactory = TransformerFactory .newInstance(); final FopFactory fopFactory = FopFactory.newInstance(); try { transformer = transformFactory .newTransformer(new StreamSource(xslt)); final Source src = new StreamSource(xmlSource); out = new FileOutputStream(tempFoFile); final Result res = new StreamResult(out); transformer.transform(src, res); System.out.println("XSLT Transform Completed"); } catch (final TransformerConfigurationException e) { err = true; e.printStackTrace(); } catch (final FileNotFoundException e) { err = true; e.printStackTrace(); } catch (final TransformerException e) { err = true; e.printStackTrace(); } finally { if (out != null) { try { out.close(); } catch (final IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } System.out.println("Initializing Preview"); transformer = null; out = null; final File fo = new File(tempFoFile); final File pdf = new File(tempPdfFile); if (!err) { final FOUserAgent ua = fopFactory.newFOUserAgent(); try { transformer = transformFactory.newTransformer(); out = new FileOutputStream(pdf); out = new BufferedOutputStream(out); final Fop fop = fopFactory.newFop( MimeConstants.MIME_PDF, ua, out); final Source foSrc = new StreamSource(fo); final Result foRes = new SAXResult(fop.getDefaultHandler()); transformer.transform(foSrc, foRes); System.out.println("Transformation Complete"); } catch (final FOPException e) { err = true; e.printStackTrace(); } catch (final FileNotFoundException e) { err = true; e.printStackTrace(); } catch (final TransformerException e) { err = true; e.printStackTrace(); } finally { if (out != null) { try { out.close(); } catch (final IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } if (!err) { System.out.println("Attempting to Preview"); final InputHandler inputHandler = new InputHandler(fo); PreviewDialog.createPreviewDialog(ua, inputHandler, true); } } // perform the clean up // f.delete(); } private String getTempDir() { final String p = "java.io.tmpdir"; return System.getProperty(p); } private String generateTempFileName() { final String charset = "abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890"; final StringBuffer sb = new StringBuffer(); Random r = new Random(); int seed = r.nextInt(); r = new Random(seed); for (int i = 0; i < 8; i++) { final int n = r.nextInt(71); seed = r.nextInt(); sb.append(charset.charAt(n)); r = new Random(seed); } return sb.toString(); } } Any help on this would be appreciated.

  • 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.

  • How to populate JList with data from another JList

    - by Zhen Le
    I have a MySQL database which contains data i would like to populate into a JList in my java program. I have two JList, one which is fill with Events Title and the second is to be fill with Guest Name. What i would like is when the user click on any of the Events Title, the second JList will show all the Guest Name that belong to that Event. I have already successfully populate the first JList with all the Events Title. What I'm having trouble with is when the user click on the Events Title, the Guests Name will show twice on the second JList. How can i make it to show only once? Here is what i got so far... Java Class private JList getJListEvents() { if (jListEvents == null) { jListEvents = new JList(); Border border = BorderFactory.createTitledBorder(BorderFactory.createBevelBorder(1, Color.black, Color.black), "Events", TitledBorder.LEFT, TitledBorder.TOP); jListEvents.setBorder(border); jListEvents.setModel(new DefaultListModel()); jListEvents.setBounds(new Rectangle(15, 60, 361, 421)); Events lEvents = new Events(); lEvents.loadEvents(jListEvents); jListEvents.addListSelectionListener(new ListSelectionListener(){ public void valueChanged(ListSelectionEvent e){ EventC eventC = new EventC(); //eventC.MonitorRegDetailsInfo(jListEvents, jTextFieldEventName, jTextFieldEventVenue, jTextFieldEventDate, jTextFieldEventTime, jTextAreaEventDesc); //eventC.MonitorRegPackageInfo(jListEvents, jTextFieldBallroom, jTextFieldBallroomPrice, jTextFieldMeal, jTextFieldMealPrice, jTextFieldEntertainment, jTextFieldEntertainmentPrice); eventC.MonitorRegGuest(jListEvents, jListGuest); } }); } return jListEvents; } Controller Class public void MonitorRegGuest(JList l, JList l2){ String event = l.getSelectedValue().toString(); Events retrieveGuest = new Events(event); retrieveGuest.loadGuests(l2); } Class with all the sql statement public void loadGuests(JList l){ ResultSet rs = null; ResultSet rs2 = null; ResultSet rs3 = null; MySQLController db = new MySQLController(); db.getConnection(); String sqlQuery = "SELECT MemberID FROM event WHERE EventName = '" + EventName + "'"; try { rs = db.readRequest(sqlQuery); while(rs.next()){ MemberID = rs.getString("MemberID"); } } catch (SQLException e) { e.printStackTrace(); } String sqlQuery2 = "SELECT GuestListID FROM guestlist WHERE MemberID = '" + MemberID + "'"; try { rs2 = db.readRequest(sqlQuery2); while(rs2.next()){ GuestListID = rs2.getString("GuestListID"); } } catch (SQLException e) { e.printStackTrace(); } String sqlQuery3 = "SELECT Name FROM guestcontact WHERE GuestListID = '" + GuestListID + "'"; try { rs3 = db.readRequest(sqlQuery3); while(rs3.next()){ ((DefaultListModel)l.getModel()).addElement(rs3.getString("Name")); } } catch (SQLException e) { e.printStackTrace(); } db.terminate(); } Thanks in advance!

    i have crm application. i have one difficulties that how i bind repeater control as message threading. like first thread as question and second thread as answer of that question. if user asked multiple question then first,second,.. threads as question and.as it is like message chatting... for keeping data from database i use this stored procedure: set ANSI_NULLS ON set QUOTED_IDENTIFIER ON GO ALTER PROCEDURE [dbo].[ViewMessageThreads] (@inquiry_id varchar(50)) AS BEGIN SET NOCOUNT ON; select i.body as master_body, h.body as history_body, q.body as question_body, q.Created_date as question_timestamp, a.body as answer_body, a.Created_date as answer_timestamp, t.Type_name as user_type from tbl_Inquiry_History i left join tbl_Inquiry_master h on h.Inquiry_id=i.Inquiry_id left join tbl_Question q on q.Inquiry_id=i.Inquiry_id left join tbl_Answer a on a.Question_id=q.Inquiry_id left join tbl_User_master u on u.Id=i.User_id left join tbl_Login_master l on l.Id=u.User_id left join tbl_Type t on t.Id = l.type_id where (i.Inquiry_id=@inquiry_id) END and this gives me result as: master_body history_body question_body question_t.. answer_body answer_t.. user_type __________________________________________________________________________________________ question 1 NULL question 1 2005-03-14... NULL NULL User question 1 NULL question 2 2005-03-14...

    Hello ... I created a table using ER/STudio 8.0.3 ... The table has a serial pk (SERIAL/INTEGER in ER/Studio)... But the ER/Studio Physical Model generated convert the Serial to Integer... And The generated table in database has a integer pk, without auto-increment functionality... Any idea?

  • Constructor versus setter injection

    - by Chris
    Hi, I'm currently designing an API where I wish to allow configuration via a variety of methods. One method is via an XML configuration schema and another method is through an API that I wish to play nicely with Spring. My XML schema parsing code was previously hidden and therefore the only concern was for it to work but now I wish to build a public API and I'm quite concerned about best-practice. It seems that many favor javabean type PoJo's with default zero parameter constructors and then setter injection. The problem I am trying to tackle is that some setter methods implementations are dependent on other setter methods being called before them in sequence. I could write anal setters that will tolerate themselves being called in many orders but that will not solve the problem of a user forgetting to set the appropriate setter and therefore the bean being in an incomplete state. The only solution I can think of is to forget about the objects being 'beans' and enforce the required parameters via constructor injection. An example of this is in the default setting of the id of a component based on the id of the parent components. My Interface public interface IMyIdentityInterface { public String getId(); /* A null value should create a unique meaningful default */ public void setId(String id); public IMyIdentityInterface getParent(); public void setParent(IMyIdentityInterface parent); } Base Implementation of interface: public abstract class MyIdentityBaseClass implements IMyIdentityInterface { private String _id; private IMyIdentityInterface _parent; public MyIdentityBaseClass () {} @Override public String getId() { return _id; } /** * If the id is null, then use the id of the parent component * appended with a lower-cased simple name of the current impl * class along with a counter suffix to enforce uniqueness */ @Override public void setId(String id) { if (id == null) { IMyIdentityInterface parent = getParent(); if (parent == null) { // this may be the top level component or it may be that // the user called setId() before setParent(..) } else { _id = Helpers.makeIdFromParent(parent,getClass()); } } else { _id = id; } } @Override public IMyIdentityInterface getParent() { return _parent; } @Override public void setParent(IMyIdentityInterface parent) { _parent = parent; } } Every component in the framework will have a parent except for the top level component. Using the setter type of injection, then the setters will have different behavior based on the order of the calling of the setters. In this case, would you agree, that a constructor taking a reference to the parent is better and dropping the parent setter method from the interface entirely? Is it considered bad practice if I wish to be able to configure these components using an IoC container? Chris

  • C# Persistent WebClient

    - by Nullstr1ng
    I have a class written in C# (Windows Forms) It's a WebClient class which I intent to use in some website and for Logging In and navigation. Here's the complete class pastebin.com (the class has 197 lines so I just use pastebin. Sorry if I made a little bit harder for you to read the class, also below this post) The problem is, am not sure why it's not persistent .. I was able to log in, but when I navigate to other page (without leaving the domain), I was thrown back to log in page. Can you help me solving this problem? one issue though is, the site I was trying to connect is "HTTPS" protocol. I have not yet tested this on just a regular HTTP.

  • What am I missing in this ASP.NET XSS Security Helper class?

    - by smartcaveman
    I need a generic method for preventing XSS attacks in ASP.NET. The approach I came up with is a ValidateRequest method that evaluates the HttpRequest for any potential issues, and if issues are found, redirect the user to the same page, but in a away that is not threatening to the application. (Source code below) While I know this method will prevent most XSS attacks, I am not certain that I am adequately preventing all possible attacks while also minimizing false positives. So, what is the most effective way to adequately prevent all possible attacks, while minimizing false positives? Are there changes I should make to the helper class below, or is there an alternative approach or third party library that offers something more convincing? public static class XssSecurity { public const string PotentialXssAttackExpression = "(http(s)*(%3a|:))|(ftp(s)*(%3a|:))|(javascript)|(alert)|(((\\%3C) <)[^\n]+((\\%3E) >))"; private static readonly Regex PotentialXssAttackRegex = new Regex(PotentialXssAttackExpression, RegexOptions.IgnoreCase); public static bool IsPotentialXssAttack(this HttpRequest request) { if(request != null) { string query = request.QueryString.ToString(); if(!string.IsNullOrEmpty(query) && PotentialXssAttackRegex.IsMatch(query)) return true; if(request.HttpMethod.Equals("post", StringComparison.InvariantCultureIgnoreCase)) { string form = request.Form.ToString(); if (!string.IsNullOrEmpty(form) && PotentialXssAttackRegex.IsMatch(form)) return true; } if(request.Cookies.Count > 0) { foreach(HttpCookie cookie in request.Cookies) { if(PotentialXssAttackRegex.IsMatch(cookie.Value)) { return true; } } } } return false; } public static void ValidateRequest(this HttpContext context, string redirectToPath = null) { if(context == null || !context.Request.IsPotentialXssAttack()) return; // expire all cookies foreach(HttpCookie cookie in context.Request.Cookies) { cookie.Expires = DateTime.Now.Subtract(TimeSpan.FromDays(1)); context.Response.Cookies.Set(cookie); } // redirect to safe path bool redirected = false; if(redirectToPath != null) { try { context.Response.Redirect(redirectToPath,true); redirected = true; } catch { redirected = false; } } if (redirected) return; string safeUrl = context.Request.Url.AbsolutePath.Replace(context.Request.Url.Query, string.Empty); context.Response.Redirect(safeUrl,true); } }

  • Issue with deserialization of a static property in .Net

    - by Punit Singhi
    I have a class called Test which has four public properties and one of them is static. the problem is after deserialization the static property contains null value. i have debugged the code and found that at server side it contains the value which is a collection , but at client side it becomes null after deserialization. i know static members doesn't serialize and deserialize so obviously it should contain the value.
