  • SPRING: How do you programmatically instantiate classes based on information passed from Flex UI

    - by babyangel86
    Imagine the UI passes back an XMl node as such: <properties> <type> Source </type> <name> Blooper </name> <delay> <type> Deterministic </type> <parameters> <param> 4 </param> </parameters> <delay> <batch> <type> Erlang </type> <parameters> <param> 4 </param> <param> 6 </param> </parameters> <batch> And behind the scene what it is asking that you instantiate a class as such: new Source("blooper", new Exp(4), new Erlang(4,6); The problem lies in the fact that you don't know what class you will need to processing, and you will be sent a list of these class definitions with instructions on how they can be linked to each other. I've heard that using a BeanFactoryPostProcessor might be helpful, or a property editor/convertor. However I am at a loss as to how best to use them to solve my problem. Any help you can provide will be much appreciated.

  • Collections not read from hibernate/ehcache second-level-cache

    - by Mark van Venrooij
    I'm trying to cache lazy loaded collections with ehcache/hibernate in a Spring project. When I execute a session.get(Parent.class, 123) and browse through the children multiple times a query is executed every time to fetch the children. The parent is only queried the first time and then resolved from the cache. Probably I'm missing something, but I can't find the solution. Please see the relevant code below. I'm using Spring (3.2.4.RELEASE) Hibernate(4.2.1.Final) and ehcache(2.6.6) The parent class: @Entity @Table(name = "PARENT") @Cacheable @Cache(usage = CacheConcurrencyStrategy.READ_WRITE, include = "all") public class ServiceSubscriptionGroup implements Serializable { /** The Id. */ @Id @Column(name = "ID") private int id; @OneToMany(fetch = FetchType.LAZY, mappedBy = "parent") @Cache(usage = CacheConcurrencyStrategy.READ_WRITE) private List<Child> children; public List<Child> getChildren() { return children; } public void setChildren(List<Child> children) { this.children = children; } @Override public boolean equals(Object o) { if (this == o) return true; if (o == null || getClass() != o.getClass()) return false; Parent that = (Parent) o; if (id != that.id) return false; return true; } @Override public int hashCode() { return id; } } The child class: @Entity @Table(name = "CHILD") @Cacheable @Cache(usage = CacheConcurrencyStrategy.READ_WRITE, include = "all") public class Child { @Id @Column(name = "ID") private int id; @ManyToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL) @JoinColumn(name = "PARENT_ID") @Cache(usage = CacheConcurrencyStrategy.READ_WRITE) private Parent parent; public int getId() { return id; } public void setId(final int id) { this.id = id; } private Parent getParent(){ return parent; } private void setParent(Parent parent) { this.parent = parent; } @Override public boolean equals(final Object o) { if (this == o) { return true; } if (o == null || getClass() != o.getClass()) { return false; } final Child that = (Child) o; return id == that.id; } @Override public int hashCode() { return id; } } The application context: <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="annotatedClasses"> <list> <value>Parent</value> <value>Child</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.SQLServer2008Dialect</prop> <prop key="hibernate.hbm2ddl.auto">validate</prop> <prop key="hibernate.ejb.naming_strategy">org.hibernate.cfg.ImprovedNamingStrategy</prop> <prop key="hibernate.connection.charSet">UTF-8</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.format_sql">true</prop> <prop key="hibernate.use_sql_comments">true</prop> <!-- cache settings ehcache--> <prop key="hibernate.cache.use_second_level_cache">true</prop> <prop key="hibernate.cache.use_query_cache">true</prop> <prop key="hibernate.cache.region.factory_class"> org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory</prop> <prop key="hibernate.generate_statistics">true</prop> <prop key="hibernate.cache.use_structured_entries">true</prop> <prop key="hibernate.cache.use_query_cache">true</prop> <prop key="hibernate.transaction.factory_class"> org.hibernate.engine.transaction.internal.jta.JtaTransactionFactory</prop> <prop key="hibernate.transaction.jta.platform"> org.hibernate.service.jta.platform.internal.JBossStandAloneJtaPlatform</prop> </props> </property> </bean> The testcase I'm running: @Test public void testGetParentFromCache() { for (int i = 0; i <3 ; i++ ) { getEntity(); } } private void getEntity() { Session sess = sessionFactory.openSession() sess.setCacheMode(CacheMode.NORMAL); Transaction t = sess.beginTransaction(); Parent p = (Parent) s.get(Parent.class, 123); Assert.assertNotNull(p); Assert.assertNotNull(p.getChildren().size()); t.commit(); sess.flush(); sess.clear(); sess.close(); } In the logging I can see that the first time 2 queries are executed getting the parent and getting the children. Furthermore the logging shows that the child entities as well as the collection are stored in the 2nd level cache. However when reading the collection a query is executed to fetch the children on second and third attempt.

    - by khue
    Hi, I have a servlet that construct response to a media file request by reading the file from server: File uploadFile = new File("C:\TEMP\movie.mov"); FileInputStream in = new FileInputStream(uploadFile); Then write that stream to the response stream. My question is how do I play the media file in the webpage using or tag to read the media stream from the response. Thank you very much. Regards K.

  • Eclipse debugging "source not found"

    - by James
    I just started using Eclipse so go easy on me ;). But when trying to debug a JUnit test case I get a dialog that states the the source is not found when I get to this line in the code in my test method: Assert.assertEquals(1, contents.size()); I know I should probably go and try and download the source from somewhere, but I really don't want to because I have no interest in stepping into the JUnit code. I have the JUnit runtime jar so Why does Eclipse expect me to have all the referenced tools source code in order to debug my own code (seems somewhat silly)? My main question is though, how can I tell Eclipse to skip this dialog when the source is not available and allow me to continue to debug my own code? [Edit] I've isolated the cause of this. It seems that Eclipse seems to think it needs the source when an exception is thrown by the internal JUnit code. In general is there anyway to tell it that it doesn't and just have it throw up an error dialog of some kind instead?

  • What is the fastest way to learn JPA ?

    - by Jacques René Mesrine
    I'm looking for the best resources (books, frameworks, tutorials) that will help me get up to speed with JPA. I've been happily using iBatis/JDBC for my persistence needs, so I need resources that will hopefully provide comparable functions on how to do things. e.g. how to I set the isolation level for each transaction ? I know there might be 10 books on the topic, so hopefully, your recommendation could narrow down to the best 2 books. Should I start with OpenJPA or are there other opensource JPA frameworks to use ? P.S. Do suggest if I should learn JPA2 or JPA1 ? My goal ultimately is to be able to write a Google App Engine app (which uses JPA1). Thanks Jacque

  • PropertyPlaceholderConfigurer vs Filters -- Spring Beans

    - by John
    Hi there. I've got a question regarding the difference between PropertyPlaceholderConfigurer (org.springframework.beans.factory.config.PropertyPlaceholderConfigurer) and normal filters defined in my pom.xml. I've been looking at examples, and it seems that even though filters are defined and marked to be active by default in the pom.xml they still make use of PropertyPlaceholderConfigurer in Spring's applicationContext.xml. This means that the pom.xml has a reference to a filter-LOCAL.properties while applicationContext.xml has a reference to application.properties and they both contain the same settings. Why is that? Is that how it is supposed to be done? I'm able to run the goal mvn jetty:run without the application.properties present, but if I add settings to the application.properties that differ from the filter-LOCAL.properties they don't seem to override. Here's an example of what I mean: pom.xml <profiles <profile <idLOCAL <activation <activeByDefaulttrue </activation <properties <envLOCAL </properties </profile </profiles applicationContext.xml <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" <property name="locations" <list <valueclasspath:application.properties </list </property <property name="ignoreResourceNotFound" value="true"/ </bean <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" <property name="driverClassName" value="${jdbc.driver}"/ <property name="url" value="${jdbc.url}"/ <property name="username" value="${jdbc.username}"/ <property name="password" value="${jdbc.password}"/ </bean an example of the content of application.properties and filters-LOCAL.properties jdbc.driver=org.postgresql.Driver jdbc.url=jdbc:postgresql://localhost/shoutbox_dev jdbc.username=tester jdbc.password=tester Can I remove the propertyConfigurer from the applicationContext, create a PROD filter and disregard the application.properties file, or will that give me issues when deploying to the production server?

  • Public static variables and Android activity life cycle management

    - by jsstp24n5
    According to the documentation the Android OS can kill the activity at the rear of the backstack. So, say for example I have an app and open the Main Activity (let's call it Activity A). In this public activity class I declare and initialize a public static variable (let's call it "foo"). In Activity A's onCreate() method I then change the value of "foo." From Activity A the user starts another activity within my app called Activity B. Variable "foo" is used in Activity B. Activity B is then paused after the user navigates to some other activities in other apps. Eventually, after a memory shortage occurs, Activity A then Activity B can be killed. After the user navigates back to my app it restarts (actually "recreates") activity B. What happens: 1) Will variable "foo" at this point have the value that was set to it when Activity A's onCreate() method ran? 2) Variable "foo" does not exist? 3) Variable "foo" exists and but is now the initialized value and not the value set in Activity A's onCreate() method?

  • Should I create protected constructor for my singleton classes?

    - by Vijay Shanker
    By design, in Singleton pattern the constructor should be marked private and provide a creational method retuning the private static member of the same type instance. I have created my singleton classes like this only. public class SingletonPattern {// singleton class private static SingletonPattern pattern = new SingletonPattern(); private SingletonPattern() { } public static SingletonPattern getInstance() { return pattern; } } Now, I have got to extend a singleton class to add new behaviors. But the private constructor is not letting be define the child class. I was thinking to change the default constructor to protected constructor for the singleton base class. What can be problems, if I define my constructors to be protected? Looking for expert views....

  • Value gets changed upon comiting. | CallableStatements

    - by Triztian
    Hello, I having a weird problem with a DAO class and a StoredProcedure, what is happening is that I use a CallableStatement object which takes 15 IN parameters, the value of the field id_color is retrieved correctly from the HTML forms it even is set up how it should in the CallableStatement setter methods, but the moment it is sent to the database the id_color is overwriten by the value 3 here's the "context": I have the following class DAO.CoverDAO which handles the CRUD operations of this table CREATE TABLE `cover_details` ( `refno` int(10) unsigned NOT NULL AUTO_INCREMENT, `shape` tinyint(3) unsigned NOT NULL , `id_color` tinyint(3) unsigned NOT NULL ', `reversefold` bit(1) NOT NULL DEFAULT b'0' , `x` decimal(6,3) unsigned NOT NULL , `y` decimal(6,3) unsigned NOT NULL DEFAULT '0.000', `typecut` varchar(10) NOT NULL, `cornershape` varchar(20) NOT NULL, `z` decimal(6,3) unsigned DEFAULT '0.000' , `othercornerradius` decimal(6,3) unsigned DEFAULT '0.000'', `skirt` decimal(5,3) unsigned NOT NULL DEFAULT '7.000', `foamTaper` varchar(3) NOT NULL, `foamDensity` decimal(2,1) unsigned NOT NULL , `straplocation` char(1) NOT NULL ', `straplength` decimal(6,3) unsigned NOT NULL, `strapinset` decimal(6,3) unsigned NOT NULL, `spayear` varchar(20) DEFAULT 'Not Specified', `spamake` varchar(20) DEFAULT 'Not Specified', `spabrand` varchar(20) DEFAULT 'Not Specified', PRIMARY KEY (`refno`) ) ENGINE=MyISAM AUTO_INCREMENT=143 DEFAULT CHARSET=latin1 $$ The the way covers are being inserted is by a stored procedure, which is the following: CREATE DEFINER=`root`@`%` PROCEDURE `putCover`( IN shape TINYINT, IN color TINYINT(3), IN reverse_fold BIT, IN x DECIMAL(6,3), IN y DECIMAL(6,3), IN type_cut VARCHAR(10), IN corner_shape VARCHAR(10), IN cutsize DECIMAL(6,3), IN corner_radius DECIMAL(6,3), IN skirt DECIMAL(5,3), IN foam_taper VARCHAR(7), IN foam_density DECIMAL(2,1), IN strap_location CHAR(1), IN strap_length DECIMAL(6,3), IN strap_inset DECIMAL(6,3) ) BEGIN INSERT INTO `dbre`.`cover_details` (`dbre`.`cover_details`.`shape`, `dbre`.`cover_details`.`id_color`, `dbre`.`cover_details`.`reversefold`, `dbre`.`cover_details`.`x`, `dbre`.`cover_details`.`y`, `dbre`.`cover_details`.`typecut`, `dbre`.`cover_details`.`cornershape`, `dbre`.`cover_details`.`z`, `dbre`.`cover_details`.`othercornerradius`, `dbre`.`cover_details`.`skirt`, `dbre`.`cover_details`.`foamTaper`, `dbre`.`cover_details`.`foamDensity`, `dbre`.`cover_details`.`strapLocation`, `dbre`.`cover_details`.`strapInset`, `dbre`.`cover_details`.`strapLength` ) VALUES (shape,color,reverse_fold, x,y,type_cut,corner_shape, cutsize,corner_radius,skirt,foam_taper,foam_density, strap_location,strap_inset,strap_length); END As you can see basically it just fills each field, now, the CoverDAO.create(CoverDTO cover) method which creates the cover is like so: public void create(CoverDTO cover) throws DAOException { Connection link = null; CallableStatement query = null; try { link = MySQL.getConnection(); link.setAutoCommit(false); query = link.prepareCall("{CALL putCover(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)}"); query.setLong(1,cover.getShape()); query.setInt(2,cover.getColor()); query.setBoolean(3, cover.getReverseFold()); query.setBigDecimal(4,cover.getX()); query.setBigDecimal(5,cover.getY()); query.setString(6,cover.getTypeCut()); query.setString(7,cover.getCornerShape()); query.setBigDecimal(8, cover.getZ()); query.setBigDecimal(9, cover.getCornerRadius()); query.setBigDecimal(10, cover.getSkirt()); query.setString(11, cover.getFoamTaper()); query.setBigDecimal(12, cover.getFoamDensity()); query.setString(13, cover.getStrapLocation()); query.setBigDecimal(14, cover.getStrapLength()); query.setBigDecimal(15, cover.getStrapInset()); query.executeUpdate(); link.commit(); } catch (SQLException e) { throw new DAOException(e); } finally { close(link, query); } } The CoverDTO is made of accessesor methods, the MySQL object basically returns the connection from a pool. Here is the pset Query with dummy but appropriate data: putCover(1,10,0,80.000,80.000,'F','Cut',0.000,0,15.000,'4x2',1.5,'A',10.000,5.000) As you can see everything is fine just when I write to the DB instead of 10 in the second parameter a 3 is written. I have done the following: Traced the id_color value to the create method, still got replaced by a 3 Hardcoded the value in the DAO create method, still got replaced by a 3 Called the procedure from the MySQL Workbench, it worked fined so I assume something is happening in the create method, any help is really appreciated.

  • Can't change the layout of alternatives keys show on android keyboard

    - by Tebam
    I want to change the default layout which Android uses for show the alternative keys when performs a long-press on a key. Keys have an attribute "android:popupKeyboard" used for define the layout of the alternative key list (which could be a Keyboard reference) but when I use it the Android's default layout still appears. Is possible to change or override this layout?

  • Having a problem getting my ActionListeners, Handlers, and GUI to communicate.

    - by badpanda
    So I am trying to get my GUI to work. When I run the code below, it does nothing, and I'm sure I'm probably just doing something dumb, but I am completely stuck... public void actionPerformed(ActionEvent e){ UI.getInstance().sS++; if((UI.getInstance().sS %2) != 0){ UI.getInstance().startStop.setName("STOP"); UI.getInstance().change.setEnabled(false); }else if(UI.getInstance().sS%2 == 0){ UI.getInstance().startStop.setName("START"); UI.getInstance().change.setEnabled(true); } } public void setStartListener(StartHandler e){ this.startStop.addActionListener(e); } sS is an int that increments every time the button startStop is clicked. change is also a button.

  • JXTreeTable and BorderHighlighter Drawing Border on All Rows

    - by Kevin Rubin
    I'm using a BorderHighlighter on my JXTreeTable to put a border above each of the table cells on non-leaf rows to give a more clear visual separator for users. The problem is that when I expand the hierarchical column, all cells in the hierarchical column, for all rows, include the Border from the Highlighter. The other columns are displaying just fine. My BorderHighlighter is defined like this: Highlighter topHighlighter = new BorderHighlighter(new HighlightPredicate() { @Override public boolean isHighlighted(Component component, ComponentAdapter adapter) { TreePath path = treeTable.getPathForRow(adapter.row); TreeTableModel model = treeTable.getTreeTableModel(); Boolean isParent = !model.isLeaf(path.getLastPathComponent()); return isParent; } }, BorderFactory.createMatteBorder(2, 0, 0, 0, Color.RED)); I'm using SwingX 1.6.5.

  • Logs are filling up with httpclient.wire.content dumps. How can I turn it off?

    - by ?????
    My catalina logs are filling up with gobs of statements like: /logs/catalina.out:2010-05-05 02:57:19,611 [Thread-19] DEBUG httpclient.wire.content - >> "[0x4] [0xc][0xd9][0xf4][0xa2]MA[0xed][0xc2][0x93][0x1b][0x15][0xfe],[0xe]h[0xb0][0x1f][0xff][0xd6][0xfb] [0x8f]O[0xd4][0xc4]0[0xab][0x80][0xe8][0xe4][0xf2][\r]I&[0xaa][0xd2]BQ[0xdb](zq[0xcd]ac[0xa8] on and on forever. I searched every config file in both tomcat and apache for the statements that purportedly turn this on as described here: http://hc.apache.org/httpclient-3.x/logging.html And I don't see where this logging as been enabled. No other .war I deployed does this. The log4j configuration block in the app isn't doing it. Any ideas? I'm using an S3 library for grails that may be the source for these. However when I run this application on my development machine (in both develop and deploy configs), I'm not seeing it.

    Hi all. I want to do search in PostgreSQL for INTEGER based columns. if (!sSearch.isEmpty()) { sSearch = sSearch.replaceAll("[^a-zA-Z0-9]", "_").toLowerCase(); String[] search = sSearch.split(" "); sWhere = " "; for (NewsColumns column : NewsColumns.values()) { for (String s : search) { sWhere += "lower(" + column + "::TEXT) LIKE '%" + s + "%' OR "; } } sWhere = sWhere.substring(0,sWhere.length()-3); } Ok, I want to convert INT value to String before search, with '::TEXT' expression.

  • JavaApplicationStub with SWT causing problems

    - by mystro
    I created an application in Eclipse that uses SWT for the GUI. I've attempted to deploy the application using the Eclipse deploy, but it seems that when I do that, LSUIElement is not respected, and I can't force the application to disappear from the dock. Nonwhistanding that issue, the application actually deploys ok and is runnable. I attempted to deploy the application using Jar Bundler, but when I try to run the application, I get the following errors: 2010-06-09 21:44:02.564 JavaApplicationStub[89045:2003] * __NSAutoreleaseNoPool(): Object 0x10021f260 of class NSCFString autoreleased with no pool in place - just leaking 2010-06-09 21:44:02.568 JavaApplicationStub[89045:2003] * __NSAutoreleaseNoPool(): Object 0x10010a0a0 of class NSCFNumber autoreleased with no pool in place - just leaking 2010-06-09 21:44:02.569 JavaApplicationStub[89045:2003] * __NSAutoreleaseNoPool(): Object 0x1001127a0 of class NSCFString autoreleased with no pool in place - just leaking 2010-06-09 21:44:02.582 JavaApplicationStub[89045:2003] * __NSAutoreleaseNoPool(): Object 0x7fff70b7af70 of class NSCFString autoreleased with no pool in place - just leaking 2010-06-09 21:44:02.583 JavaApplicationStub[89045:2003] * __NSAutoreleaseNoPool(): Object 0x100123ea0 of class NSCFData autoreleased with no pool in place - just leaking 2010-06-09 21:44:02.587 JavaApplicationStub[89045:2003] * __NSAutoreleaseNoPool(): Object 0x100225b90 of class NSCFDictionary autoreleased with no pool in place - just leaking 2010-06-09 21:44:02.588 JavaApplicationStub[89045:2003] * __NSAutoreleaseNoPool(): Object 0x100225ee0 of class __NSFastEnumerationEnumerator autoreleased with no pool in place - just leaking in a very, very, very, long list. The application launches and appears to hang with the icon constantly bouncing in the dock, and the first GUI menu only partially loaded (it looks like one of the text boxes is semi visible, and the overall rectangle is the right size, but the GUI is not showing properly. It is essentially hung.) I'm hoping someone has had experience with this problem, and may be able to help! Thanks!
