  • Resizing JPopupMenu and avoiding a "flicker" issue

    - by Avrom
    Hi, I am trying to implement a search results popup list similar to the style found here: http://www.inquisitorx.com/ (I'm not trying to implement a Google search, I'm just using this as a rough example of the style I'm working on.) In any event, I am implementing this by using a JList contained within a JPopupMenu which is popped up underneath a JTextField. When a user enters search terms, the list changes to reflect different matching results. I then call pack on the JPopupMenu to resize it. This works, however, it creates a slight flicker effect since it is actually hiding the popup and showing a popup. (See the private method getPopup in JPopupMenu where it explicitly does this.) Is there any way to just get it to just resize itself (aside from using a JWindow)?

  • thoughs on using Alpha Five v10 with Codeless AJAX for building an AJAX database app in a short amou

    - by william Hunter
    I need to build an AJAX application against our MS SQL Server database for my company. the app has to have user permissions and reporting and is pretty complex. I am really under the gun in terms of time. The company that I work for needs the app for an important project launch. A colleague/friend of mine in a different company recommended that I look at a product from Alpha Software called Alpha Five v10 with Codeless AJAX. He has told me that he has used it extensively and that it saves him a "serious boat load of time" and he says that he has not run into limitations because you can also write your own JavaScript or you wire in JQERY. Before I commit to Alpha Five v10, I would like to get any other opinions? Thanks. Norman Stern. Chicago

  • How to transform SoapFault to SoapMessage via Interceptor in CXF?

    - by Michal Mech
    I have web-service created and configured via Spring and CXF. See beans below: <?xml version="1.0" encoding="UTF-8"?> <beans <!-- ommited -->> <import resource="classpath:META-INF/cxf/cxf.xml" /> <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" /> <import resource="classpath:META-INF/cxf/cxf-servlet.xml" /> <bean id="internalActService" class="package.InternalActServiceImpl" /> <jaxws:endpoint implementor="#internalActService" address="/InternalActService"> <jaxws:properties> <entry key="schema-validation-enabled" value="true" /> </jaxws:properties> <jaxws:outFaultInterceptors> <bean class="package.InternalActServiceFaultOutInterceptor" /> </jaxws:outFaultInterceptors> </jaxws:endpoint> </beans> As can you see I added schema validation to my web service. But CXF throws SoapFault when request is not corresponding with schema. I want to send to the client SoapMessage instead of SoapFault, that's why I added outFaultInterceptors. My question is how to transform SoapFault to SoapMessage? I've made few tries but I don't know how to implement outFaultInterceptor.

  • Weaknesses of Hibernate

    - by Sinuhe
    I would like to know which are the weak points of Hibernate 3. This is not pretended to be a thread against Hibernate. I think it will be a very useful knowledge for decide if Hibernate is the best option for a project or for estimating its time. A weakness can be: A bug Where JDBC or PLSQL are better Performance issues ... Also, can be useful to know some solutions for that problems, better ORM or techniques, or it will be corrected in Hibernate 4. For example, AFAIK, Hibernate will have a very bad performance updating 10000 rows comparing to JDBC in this query: update A set state=3 where state=2

  • JPA One To Many Relationship Persistence Bug

    - by Brian
    Hey folks, I've got a really weird problem with a bi-directional relationship in jpa (hibernate implementation). A User is based in one Region, and a Region can contain many Users. So...relationship is as follows: Region object: @OneToMany(mappedBy = "region", fetch = FetchType.LAZY, cascade = CascadeType.ALL) public Set<User> getUsers() { return users; } public void setUsers(Set<User> users) { this.users = users; } User object: @ManyToOne(cascade = {CascadeType.PERSIST, CascadeType.MERGE}, fetch = FetchType.EAGER) @JoinColumn(name = "region_fk") public Region getRegion() { return region; } public void setRegion(Region region) { this.region = region; } So, the relationship as you can see above is Lazy on the region side, ie, I don't want the region to eager load all the users. Therefore, I have the following code within my DAO layer to add a user to an existing user to an existing region object... public User setRegionForUser(String username, Long regionId){ Region r = (Region) this.get(Region.class, regionId); User u = (User) this.get(User.class, username); u.setRegion(r); Set<User> users = r.getUsers(); users.add(u); System.out.println("The number of users in the set is: "+users.size()); r.setUsers(users); this.update(r); return (User)this.update(u); } The problem is, when I run a little unit test to add 5 users to my region object, I see that the region.getUsers() set always stays stuck at 1 object...somehow the set isn't getting added to. My unit test code is as follows: public void setUp(){ System.out.println("calling setup method"); Region r = (Region)ManagerFactory.getCountryAndRegionManager().get(Region.class, Long.valueOf("2")); for(int i = 0; i<loop; i++){ User u = new User(); u.setUsername("username_"+i); ManagerFactory.getUserManager().update(u); ManagerFactory.getUserManager().setRegionForUser("username_"+i, Long.valueOf("2")); } } public void tearDown(){ System.out.println("calling teardown method"); for(int i = 0; i<loop; i++){ ManagerFactory.getUserManager().deleteUser("username_"+i); } } public void testGetUsersForRegion(){ Set<User> totalUsers = ManagerFactory.getCountryAndRegionManager().getUsersInRegion(Long.valueOf("2")); System.out.println("Expecting 5, got: "+totalUsers.size()); this.assertEquals(5, totalUsers.size()); } So the test keeps failing saying there is only 1 user instead of the expected 5. Any ideas what I'm doing wrong? thanks very much, Brian

  • Throw a long list of exceptions vs throw an Exception vs throw custom exception?

    - by athena
    I have an application which uses two methods of an API. Both these methods throw more than five exceptions each. So, if I just add a throws declaration then it becomes a list of more than ten. (My method cannot handle any of the ten exceptions) I have read that throwing a long list of exceptions is a bad practice. Also throwing (the umbrella) Exception is a bad practice. So, what should I do? Add a try catch block, and log and exit in the catch block? (Current approach) Create a custom exception class, wrap every exception and throw the custom exception? Add a throws declaration for all exceptions? Throw Exception?

  • How to properly test Hibernate length restriction?

    - by Cesar
    I have a POJO mapped with Hibernate for persistence. In my mapping I specify the following: <class name="ExpertiseArea"> <id name="id" type="string"> <generator class="assigned" /> </id> <version name="version" column="VERSION" unsaved-value="null" /> <property name="name" type="string" unique="true" not-null="true" length="100" /> ... </class> And I want to test that if I set a name longer than 100 characters, the change won't be persisted. I have a DAO where I save the entity with the following code: public T makePersistent(T entity){ transaction = getSession().beginTransaction(); transaction.begin(); try{ getSession().saveOrUpdate(entity); transaction.commit(); }catch(HibernateException e){ logger.debug(e.getMessage()); transaction.rollback(); } return entity; } Actually the code above is from a GenericDAO which all my DAOs inherit from. Then I created the following test: public void testNameLengthMustBe100orLess(){ ExpertiseArea ea = new ExpertiseArea( "1234567890" + "1234567890" + "1234567890" + "1234567890" + "1234567890" + "1234567890" + "1234567890" + "1234567890" + "1234567890" + "1234567890"); assertTrue("Name should be 100 characters long", ea.getName().length() == 100); ead.makePersistent(ea); List<ExpertiseArea> result = ead.findAll(); assertEquals("Size must be 1", result.size(),1); ea.setName(ea.getName()+"1234567890"); ead.makePersistent(ea); ExpertiseArea retrieved = ead.findById(ea.getId(), false); assertTrue("Both objects should be equal", retrieved.equals(ea)); assertTrue("Name should be 100 characters long", (retrieved.getName().length() == 100)); } The object is persisted ok. Then I set a name longer than 100 characters and try to save the changes, which fails: 14:12:14,608 INFO StringType:162 - could not bind value '12345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890' to parameter: 2; data exception: string data, right truncation 14:12:14,611 WARN JDBCExceptionReporter:100 - SQL Error: -3401, SQLState: 22001 14:12:14,611 ERROR JDBCExceptionReporter:101 - data exception: string data, right truncation 14:12:14,614 ERROR AbstractFlushingEventListener:324 - Could not synchronize database state with session org.hibernate.exception.DataException: could not update: [com.exp.model.ExpertiseArea#33BA7E09-3A79-4C9D-888B-4263314076AF] //Stack trace 14:12:14,615 DEBUG GenericDAO:87 - could not update: [com.exp.model.ExpertiseArea#33BA7E09-3A79-4C9D-888B-4263314076AF] 14:12:14,616 DEBUG JDBCTransaction:186 - rollback 14:12:14,616 DEBUG JDBCTransaction:197 - rolled back JDBC Connection That's expected behavior. However when I retrieve the persisted object to check if its name is still 100 characters long, the test fails. The way I see it, the retrieved object should have a name that is 100 characters long, given that the attempted update failed. The last assertion fails because the name is 110 characters long now, as if the ea instance was indeed updated. What am I doing wrong here?

  • How to make an entity out of a join table without primary key

    - by tputkonen
    I'm trying to generate JPA entities out of an existing database having an "interesting" design. Database has a table called UserSet, which can have links to several other UserSets. There is a one to many relation between UserSets and LinkedUserSets. LinkedUserSets also has one to one relation to UserSets. I tried to generate a JPA Entity out of the database structure using Dali JPA Tools. The resulting entity Linkeduserset misses @Id or @EmbeddedId annotation and thus failes to compile. As the resulting entity contains only two @JoinColumns (which cannot be marked as @Id), I have not so far found a way around this issue. Database structure can not be modified in any way. Is there a way to overcome this somehow? Relevant pars of create table statements: CREATE TABLE `LinkedUserSets` ( `UsrSetID` INT(11) NOT NULL DEFAULT '0' , `ChildID` INT(11) NOT NULL DEFAULT '0' , CONSTRAINT `fk_LinkedUserSets_UserSet1` FOREIGN KEY (`UsrSetID` ) REFERENCES `UserSet` (`UsrSetID` )); CREATE TABLE `UserSet` ( `UsrSetID` INT(11) NOT NULL AUTO_INCREMENT , PRIMARY KEY (`UsrSetID`), CONSTRAINT `fk_UserSet_LinkedUserSets1` FOREIGN KEY (`UsrSetID` ) REFERENCES `LinkedUserSets` (`ChildID` )); Generated entities: @Entity @Table(name="linkedusersets") public class Linkeduserset { //bi-directional many-to-one association to Userset @ManyToOne @JoinColumn(name="UsrSetID") private Userset userset1; //bi-directional one-to-one association to Userset @OneToOne @JoinColumn(name="ChildID") private Userset userset2; } @Entity @Table(name="userset") public class Userset { private static final long serialVersionUID = 1L; @Id @Column(name="UsrSetID") private int jngSetID; //bi-directional many-to-one association to Linkeduserset @OneToMany(mappedBy="userset1") private Set<Linkeduserset> linkedusersets; //bi-directional one-to-one association to Linkeduserset @OneToOne(mappedBy="userset2") private Linkeduserset linkeduserset; } Error message: Entity "Linkeduserset" has no Id or EmbeddedId

  • How to work with BufferedImage and YCbCr colorspace?

    Hi everyone! I need to translate colors in bitmap loaded to BufferedImage from RGB to YCbCr (luminance and 2 channels chrominance) and back after process. I made it with functions used like rgb2ycbcr() in main method for each pixel, but it isn't so smart solution. I should use ColorSpace and ColorModel classes to get BufferedImage with correct color space. It would be more flexible method, but I don't know how to do that. I'm lost and I need some tips. Can somebody help me?

  • Spring - Transaction Readonly

    - by AAK
    Hello Gurus! Just wanted your expert opinions on declarative transaction management for Spring. Here is my setup - A. DAO Layer is Plain old JDBC using jdbcTemplete (No hibernate etc) B. Service Layer is POJO with declarative trasnactions as follows - save*, readonly=false, rollback for Throwable Things work fine with above setup. However when I say get*, readonly=true I see errors in my log file saying - Database connection cannot be marked as readonly. This happens for all get* methods in Service Layer. Now my questions - A. Do I have to say get* as readonly? All my get* methods are pure read DB operations. I do not wish to run them in any transaction context. How serious is the above error? B. When I remove the get* confiiguration, I do not see the errors, morever all my simple get* operations are performed without transactions. Is this the way to go? C. Why would anyone want to have transactional methods where readonly = true? Is there any practical significance of this configuration? Thank you! As always your resposes are much appreciated!

  • Correct algorith for checking leap year

    - by Debanjan
    What will be the exact definition of leap year ? AFAIK "A year which is divisible by 4 is a leap year.But for century years' the years which are divisible by 400 is a leap year." But that definition makes 100, 200, 300, 400.... upto 1700 NOT LEAP years! But in Gregorian calender all of them are all leap year,check this out. You can also try "call 1700" in Linux to verify. So the correct algorithm foe leap year would be if ( (year % 4 == 0) && ( year <= 1700 || year % 100 != 0 || year % 400 == 0 )) printf("%d is a leap year.\n", year); else printf("%d is not a leap year.\n", year); But is this specific to Gregorian calender ? Even if that is the case why is it not mentioned here ? Regards, PS:The history of Gregorian callender seems interesting check out the September month of 1752.

  • JXMapViewer change orientation to Heading Up

    - by Charlie
    I am trying to use JXMapViewer (from swingx-ws) with Open Street Maps. I was wondering if it would be possible to display the map tiles in the JXMapViewer based on heading up, rather than on North up. For example, the normal car GPS navigation systems let you do that. I've looked through the documentation and there doesn't seem to be a straightforward way to do this. Is there something else that accomplish this, besides JXMapViewer?

  • How do I get a JPanel with an empty JLabel to take up space in a GridBagLayout

    - by user2888663
    I am working on a GUI for a project at school. I am using a GridBagLayout in swing. I want to have a label indicating the input(a type of file @ x = 0, y = 0), followed by another label(the actual file name once selected @ x = 1, y = 0), followed by a browse button for a file chooser( @ x = 2, y = 0). The label at (1,0) is initially blank, however I want the area that the text will occupy to take up some space when the label contains no text. I also want the space between the label at (0,0) and the button at (2,0) to remain constant. To achieve this, I'm trying to put the label onto a panel and then play with the layouts. However I can't seam to achieve the desired results. Could anyone offer some suggestions? The next three rows of the GridBagLayout will be laid out exactly the same way. Here is a link to a screen shot of the GUI. calibrationFileSelectionValueLabel = new JLabel("",Label.LEFT); calibrationFileSelectionValueLabel.setName("calibrationFileSelection"); calibrationFileSelectionValueLabel.setMinimumSize(new Dimension(100,0)); calibrationFileSelectionValuePanel = new JPanel(); calibrationFileSelectionValuePanel.setBorder(BorderFactory.createEtchedBorder()); calibrationFileSelectionValuePanel.add(calibrationFileSelectionValueLabel); c.gridx = 0; c.gridy = 0; c.fill = GridBagConstraints.NONE; filesPanel.add(calibrationFileLabel,c); c.gridy = 1; filesPanel.add(frequencyFileLabel,c); c.gridy = 2; filesPanel.add(sampleFileLabel,c); c.gridy = 3; filesPanel.add(outputFileLabel,c); c.gridx = 1; c.gridy = 0; c.fill = GridBagConstraints.BOTH; // filesPanel.add(calibrationFileSelection,c); filesPanel.add(calibrationFileSelectionValuePanel,c); c.gridy = 1; // filesPanel.add(frequencyFileSelection,c); filesPanel.add(frequencyFileSelectionValueLabel,c); c.gridy = 2; // filesPanel.add(sampleFileSelection,c); filesPanel.add(sampleFileSelectionValueLabel,c); c.gridy = 3; // filesPanel.add(outputFileSelection,c); filesPanel.add(outputFileSelectionValueLabel,c); c.gridx = 2; c.gridy = 0; c.fill = GridBagConstraints.NONE; filesPanel.add(calibrationFileSelectionButton,c); c.gridy = 1; filesPanel.add(frequencyFileSelectionButton,c); c.gridy = 2; filesPanel.add(sampleFileSelectionButton,c); c.gridy = 3; filesPanel.add(createOutputFileButton,c); panelForFilesPanelBorder = new JPanel(); panelForFilesPanelBorder.setBorder(BorderFactory.createCompoundBorder(new EmptyBorder(5,10,5,10), BorderFactory.createEtchedBorder())); panelForFilesPanelBorder.add(filesPanel); buttonsPanel = new JPanel(); buttonsPanel.setLayout(new FlowLayout(FlowLayout.CENTER)); buttonsPanel.setBorder(BorderFactory.createCompoundBorder(new EmptyBorder(5,10,10,10), BorderFactory.createEtchedBorder())); buttonsPanel.add(startButton); buttonsPanel.add(stopButton); basePanel.add(panelForFilesPanelBorder); basePanel.add(numericInputPanel); basePanel.add(buttonsPanel);

  • Aborting upload from a servlet

    - by Zizzencs
    I'd like to limit the size of the file that can be uploaded to an application. To achieve this, I'd like to abort the upload process from the server side when the size of the file being uploaded exceeds a limit. Is there a way to abort an upload process from the server side without waiting the HTTP request to finish?
