  • Importing hibernate configuration file into Spring applicationContext

    - by Himanshu Yadav
    I am trying to integrate Hibernate 3 with Spring 3.1.0. The problem is that application is not able to find mapping file which declared in hibernate.cfg.xml file. Initially hibernate configuration has datasource configuration, hibernate properties and mapping hbm.xml files. Master hibernate.cfg.xml file exist in src folder. this is how Master file looks: <hibernate-configuration> <session-factory> <!-- Mappings --> <mapping resource="com/test/class1.hbm.xml"/> <mapping resource="/class2.hbm.xml"/> <mapping resource="com/test/class3.hbm.xml"/> <mapping resource="com/test/class4.hbm.xml"/> <mapping resource="com/test/class5.hbm.xml"/> Spring config is: <bean id="sessionFactoryEditSolution" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="data1"/> <property name="mappingResources"> <list> <value>/master.hibernate.cfg.xml</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop> <prop key="hibernate.cache.use_second_level_cache">true</prop> </props> </property> </bean>

  • [Java2D] Is this bad practice? Multiple Graphics2D Objects

    - by m00st
    I've created a JPanel canvas that holds all graphics; namely JLabel. To get animated sprites to work you have to over ride the paintComponent of the extended JLabel class. I've successfully implemented animated sprites this way. Is it bad practice to have a Graphics2D canvas and then have multiple 'images' in their own Graphics2D?

  • Returning in a static class constructor

    - by Martijn Courteaux
    Hello, This isn't valid code: public class MyClass { private static boolean yesNo = false; static { if (yesNo) { System.out.println("Yes"); return; // The return statement is the problem } System.exit(0); } } This is a stupid example, but in a static class constructor we can't return;. Why? Are there good reasons for this? Does someone know something more about this? So the reason why I should do return is to end constructing there. Thanks

  • KeyListener problem

    - by rgksugan
    In my apllication i am using a jpanel in which i want to add a key listener. I did it. But it doesnot work.

Here is my code to update the panel RenderedImage image = ImageIO.read(new ByteArrayInputStream((byte[]) get())); Graphics graphics = remote.rdpanel.getGraphics(); if (graphics != null) { Image readyImage = new ImageIcon(UtilityFunctions.convertRenderedImage(image)).getImage(); graphics.drawImage(readyImage, 0, 0, remote.rdpanel.getWidth(), remote.rdpanel.getHeight(), null); }

  • Servlet Session - switch from URL Rewriting to Cookie

    - by lajuette
    Situation: I have a "dumb" Javascript frontend that can contact some kind of SSO middleware (MW). The MW can obtain sessions by issuing requests that contain authentication credentials (username, password). I.e. the session will be created for a certain user. My frontend needs to "restart" the session to gain the user's permissions to the target system. For that i need a valid session cookie. The target system is not under my control (could be a more or less public WFS, WMS, etc.), so i cannot add any SSO mechanism to it. Question: Is it possible to "steal" a Session forging a request which URL contains a valid session ID in the jsessionid parameter? Goal : Issue such a request to a Servlet and make it respond with a Set-Cookie header that contains the same id. That way the frontend joins the session and may do whatever the user, which was used to create the session, is able to do.

  • JSF 2.0 Dynamic Views

    - by Robe Eleckers
    Hello, I'm working on a web project which uses JSF 2.0, PrimeFaces and PrettyFaces as main frameworks / libraries. The pages have the following (common) structure: Header, Content, Footer. Header: The Header always contains the same menu. This menu is a custom component, which generates a recursive html <ul><li> list containing <a href="url"> html links, this is all rendered with a custom renderer. The link looks like 'domain.com/website/datatable.xhtml?ref=2'. Where the ref=2 used to load the correct content from the database. I use prettyfaces to store this request value in a backingbean. Question 1: Is it ok to render the <a href> links myself, or should I better add an HTMLCommandLink from my UIComponent and render that in the encodeBegin/End? Question 2: I think passing variables like this is not really the JSF 2.0 style, how to do this in a better way? Content: The content contains dynamic data. It can be a (primefaces) datatable, build with dynamic data from the database. It can also be a text page, also loaded from the database. Or a series of graphs. You got the point, it's dynamic. The content is based on the link pressed in the header menu. If the content is of type datatable, then I put the ref=2 variable to a DataTableBean (via prettyfaces), which then loads the correct datatable from the database. If the content is of type chart, I'll put it on the ChartBean. Question 3: Is this a normal setup? Ideally I would like to update my content via Ajax. I hope it's clear :)

  • Putting Select Statement on Hibernate Transaction

    - by Mark Estrada
    Hi All, I have been reading the net for a while regarding Hibernate but I can seem to understand one concept regarding Transaction. On some site that I have visit, Select statements are in transaction mode like this. public List<Book> readAll() { Session session = HibernateUtil.getSessionFactory() .getCurrentSession(); session.beginTransaction(); List<Book> booksList = session.createQuery("from Book").list(); session.getTransaction().commit(); return booksList; } While on some site, it does not advocate the use of transaction on Select statements public List<Book> readAll() { Session session = HibernateUtil.getSessionFactory() .getCurrentSession(); List<Book> booksList = session.createQuery("from Book").list(); return booksList; } I am thinking which one should I follow. Any thoughts please? Are transactions needed on Select Statements or not? Thanks

  • JPA Secondary Table Issue

    - by Smithers
    I have a three tables: User, Course, and Test. Course has a User foreign key and Test has a Course foreign key. I am having trouble mapping the Test collection for each User since I need an intermediary step from User - Course - Test. I am trying to use a SecondaryTable since the User key for the Test is its associated Course row. Am I on the right track using SecondaryTable or is there a way to use a JoinTable without the inverseJoinColumn?

  • How to suppress/control logging of Wagon-FTP Maven extension?

    - by Vincenzo
    I'm deploying Maven site by FTP, using Wagon-FTP. Works fine, but output is full of FTP connection/authentication details, which effectively expose logins and passwords to everybody (especially if the project is open source and its CI protocols are publicly accessible): [...] [INFO] [INFO] --- maven-site-plugin:3.0-beta-3:deploy (default-deploy) @ rempl --- Reply received: 220---------- Welcome to Pure-FTPd [privsep] [TLS] ---------- 220-You are user number 1 of 50 allowed. 220-Local time is now 09:08.

  • J2ME Reduce Image color-depth/ Compress Image size

    - by updateraj
    Hi, I need to transmit the image from the mobile phone to the server. I am able to reduce the image screen size but not the memory size. I understand i have to deal with the color depth. J2ME does not seem to offer any scaling method which is available in J2SE: image rescaled = image.getScaledInstance(thumbWidth, thumbHeight, Image.SCALE_AREA_AVERAGING); BufferedImage biRescaled = toBufferedImage(rescaled, thumbWidth, thumbHeight, BufferedImage.TYPE_INT_RGB); How i would i tackle this ? I would like to reduce the image memory size before i transmit to the server. Thank you

  • How do you do a limit query in HQL

    - by stevedbrown
    In Hibernate 3, is there a way to do the equivalent of the following MySql limit in HQL. select * from a_table order by a_table_column desc limit 0, 20; I don't want to use setMaxResults if possible. This definitely was possible in the older version of Hibernate/HQL, but seems to have disappeared.

  • Why linking doesn't work in my Xtext-based DSL?

    - by reprogrammer
    The following is the Xtext grammar for my DSL. Model: variableTypes=VariableTypes predicateTypes=PredicateTypes variableDeclarations= VariableDeclarations rules=Rules; VariableType: name=ID; VariableTypes: 'var types' (variableTypes+=VariableType)+; PredicateTypes: 'predicate types' (predicateTypes+=PredicateType)+; PredicateType: name=ID '(' (variableTypes+=[VariableType|ID])+ ')'; VariableDeclarations: 'vars' (variableDeclarations+=VariableDeclaration)+; VariableDeclaration: name=ID ':' type=[VariableType|ID]; Rules: 'rules' (rules+=Rule)+; Rule: head=Head ':-' body=Body; Head: predicate=Predicate; Body: (predicates+=Predicate)+; Predicate: predicateType=[PredicateType|ID] '(' (terms+=Term)+ ')'; Term: variable=Variable; Variable: variableDeclaration=[VariableDeclaration|ID]; terminal WS: (' ' | '\t' | '\r' | '\n' | ',')+; And, the following is a program in the above DSL. var types Node predicate types Edge(Node, Node) Path(Node, Node) vars x : Node y : Node z : Node rules Path(x, y) :- Edge(x, y) Path(x, y) :- Path(x, z) Path(z, y) When I used the generated Switch class to traverse the EMF object model corresponding to the above program, I realized that the nodes are not linked together properly. For example, the getPredicateType() method on a Predicate node returns null. Having read the Xtext user's guide, my impression is that the Xtext default linking semantics should work for my DSL. But, for some reason, the AST nodes of my DSL don't get linked together properly. Can anyone help me in diagnosing this problem?

  • Why does "request.getUserPrincipal().getName()" sometimes return a blank string?

    - by Marcus
    Has somebody an idea, why the getName method of the requests getUserPrincipal Method sometimes provides an empty String? Most of the time it returns the correct user name but not every time. This behaviour does occur randonmly. I can start the application, run the command and it works. The next time I start the application and run the command (exactly the same way as before!) it does not work... Any ideas?

  • Method return type

    - by sarah xia
    Hi, In my company, a system is designed to have 3 layers. Layer1 is responsible for business logic handling. Layer3 is calling back end systems. Layer2 sits between the two layers so that layer1 doesn't need to know about the back end systems. To replay information from layer3, layer2 needs to define interface to layer1. For example, layer1 wants to check if a PIN from user is correct. It calls layer2 checkPin() method and then layer2 calls the relevant back end system. The checkPin() results could be: correctPin, inCorrectPin and internalError. At the moment, we defined the return type 'int'. So if layer2 returns 0, it means correctPin; if 1 is returned, it means inCorrectPin; if 9 is returned it means internalError. It works. However I feel a bit uneasy about this approach. Are there better ways to do it? For example define an enum CheckPinResult{CORRECT_PIN,INCORRECT_PIN,INTERNAL_ERROR}, and return CheckPinResult type? Thanks, Sarah

  • Iterables.find and Iterators.find - instead of throwing exception, get null

    - by mjlee
    I'm using google-collections and trying to find the first element that satisfies Predicate if not, return me 'null'. Unfortunately, Iterables.find and Iterators.find throws NoSuchElementException when no element is found. Now, I am forced to do Object found = null; if ( Iterators.any( newIterator(...) , my_predicate ) { found = Iterators.find( newIterator(...), my_predicate ) } I can surround by 'try/catch' and do the same thing but for my use-cases, I am going to encounter many cases where no-element is found. Is there a simpler way of doing this?

  • ivy dependency on external JAR
