  • I'm using spring, hibernate and mysql. How can I let my app create the table automatically.

    - by Yousui
    Hi guys, I'm using spring, all my annotated entity class information are put in the ApplicationContext.xml. I'm using a MySql database, now how can I use the SchemaExport function in hibernate to create the tables? My application can't create the table automatically, though i have set <prop key="hbm2ddl.auto">create</prop>. This is my ApplicationContext.xml: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql:///edde" /> <property name="username" value="root" /> <property name="password" value="" /> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="annotatedClasses"> <list> <value>com.edde.Book</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="current_session_context_class">thread</prop> <prop key="show_sql">true</prop> <prop key="hbm2ddl.auto">create</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.use_sql_comments">true</prop> <prop key="hibernate.format_sql">true</prop> </props> </property> </bean> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <tx:annotation-driven transaction-manager="transactionManager" /> <bean id="bookDao" class="com.edde.BookDao"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <bean id="bookService" class="com.edde.BookServiceImpl"> <property name="dao" ref="bookDao"></property> </bean> </beans> This is my test application: package com.edde; import org.springframework.context.support.ClassPathXmlApplicationContext; public class Test { /** * @param args */ public static void main(String[] args) { ClassPathXmlApplicationContext factory = new ClassPathXmlApplicationContext("applicationContext.xml"); BookService service = (BookService) factory.getBean("bookService"); Book book = new Book(); book.setBookName("great book"); service.saveBook(book); } } When I run my app, I get this error: 2010-05-20 17:25:20,777 DEBUG [org.hibernate.SQL] - /* insert com.edde.Book */ insert into Book (author, bookName, publication) values (?, ?, ?)

  • Java Logger API

    - by Koppar
    This is a more like a tip rather than technical write up and serves as a quick intro for newbies. The logger API helps to diagnose application level or JDK level issues at runtime. There are 7 levels which decide the detailing in logging (SEVERE, WARNING, INFO, CONFIG, FINE, FINER, FINEST). Its best to start with highest level and as we narrow down, use more detailed logging for a specific area. SEVERE is the highest and FINEST is the lowest. This may not make sense until we understand some jargon. The Logger class provides the ability to stream messages to an output stream in a format that can be controlled by the user. What this translates to is, I can create a logger with this simple invocation and use it add debug messages in my class: import java.util.logging.*; private static final Logger focusLog = Logger.getLogger("java.awt.focus.KeyboardFocusManager"); if (focusLog.isLoggable(Level.FINEST)) { focusLog.log(Level.FINEST, "Calling peer setCurrentFocusOwner}); LogManager acts like a book keeper and all the getLogger calls are forwarded to LogManager. The LogManager itself is a singleton class object which gets statically initialized on JVM start up. More on this later. If there is no existing logger with the given name, a new one is created. If there is one (and not yet GC’ed), then the existing Logger object is returned. By default, a root logger is created on JVM start up. All anonymous loggers are made as the children of the root logger. Named loggers have the hierarchy as per their name resolutions. Eg: java.awt.focus is the parent logger for java.awt.focus.KeyboardFocusManager etc. Before logging any message, the logger checks for the log level specified. If null is specified, the log level of the parent logger will be set. However, if the log level is off, no log messages would be written, irrespective of the parent’s log level. All the messages that are posted to the Logger are handled as a LogRecord object.i.e. FocusLog.log would create a new LogRecord object with the log level and message as its data members). The level of logging and thread number are also tracked. LogRecord is passed on to all the registered Handlers. Handler is basically a means to output the messages. The output may be redirected to either a log file or console or a network logging service. The Handler classes use the LogManager properties to set filters and formatters. During initialization or JVM start up, LogManager looks for logging.properties file in jre/lib and sets the properties if the file is provided. An alternate location for properties file can also be specified by setting java.util.logging.config.file system property. This can be set in Java Control Panel ? Java ? Runtime parameters as -Djava.util.logging.config.file = <mylogfile> or passed as a command line parameter java -Djava.util.logging.config.file = C:/Sunita/myLog The redirection of logging depends on what is specified rather registered as a handler with JVM in the properties file. java.util.logging.ConsoleHandler sends the output to system.err and java.util.logging.FileHandler sends the output to file. File name of the log file can also be specified. If you prefer XML format output, in the configuration file, set java.util.logging.FileHandler.formatter = java.util.logging.XMLFormatter and if you prefer simple text, set set java.util.logging.FileHandler.formatter =java.util.logging.SimpleFormatter Below is the default logging Configuration file: ############################################################ # Default Logging Configuration File # You can use a different file by specifying a filename # with the java.util.logging.config.file system property. # For example java -Djava.util.logging.config.file=myfile ############################################################ ############################################################ # Global properties ############################################################ # "handlers" specifies a comma separated list of log Handler # classes. These handlers will be installed during VM startup. # Note that these classes must be on the system classpath. # By default we only configure a ConsoleHandler, which will only # show messages at the INFO and above levels. handlers= java.util.logging.ConsoleHandler # To also add the FileHandler, use the following line instead. #handlers= java.util.logging.FileHandler, java.util.logging.ConsoleHandler # Default global logging level. # This specifies which kinds of events are logged across # all loggers. For any given facility this global level # can be overriden by a facility specific level # Note that the ConsoleHandler also has a separate level # setting to limit messages printed to the console. .level= INFO ############################################################ # Handler specific properties. # Describes specific configuration info for Handlers. ############################################################ # default file output is in user's home directory. java.util.logging.FileHandler.pattern = %h/java%u.log java.util.logging.FileHandler.limit = 50000 java.util.logging.FileHandler.count = 1 java.util.logging.FileHandler.formatter = java.util.logging.XMLFormatter # Limit the message that are printed on the console to INFO and above. java.util.logging.ConsoleHandler.level = INFO java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter ############################################################ # Facility specific properties. # Provides extra control for each logger. ############################################################ # For example, set the com.xyz.foo logger to only log SEVERE # messages: com.xyz.foo.level = SEVERE Since I primarily use this method to track focus issues, here is how I get detailed awt focus related logging. Just set the logger name to java.awt.focus.level=FINEST and change the default log level to FINEST. Below is a basic sample program. The sample programs are from http://www2.cs.uic.edu/~sloan/CLASSES/java/ and have been modified to illustrate the logging API. By changing the .level property in the logging.properties file, one can control the output written to the logs. To play around with the example, try changing the levels in the logging.properties file and notice the difference in messages going to the log file. Example --------KeyboardReader.java------------------------------------------------------------------------------------- import java.io.*; import java.util.*; import java.util.logging.*; public class KeyboardReader { private static final Logger mylog = Logger.getLogger("samples.input"); public static void main (String[] args) throws java.io.IOException { String s1; String s2; double num1, num2, product; // set up the buffered reader to read from the keyboard BufferedReader br = new BufferedReader (new InputStreamReader (System.in)); System.out.println ("Enter a line of input"); s1 = br.readLine(); if (mylog.isLoggable(Level.SEVERE)) { mylog.log (Level.SEVERE,"The line entered is " + s1); } if (mylog.isLoggable(Level.INFO)) { mylog.log (Level.INFO,"The line has " + s1.length() + " characters"); } if (mylog.isLoggable(Level.FINE)) { mylog.log (Level.FINE,"Breaking the line into tokens we get:"); } int numTokens = 0; StringTokenizer st = new StringTokenizer (s1); while (st.hasMoreTokens()) { s2 = st.nextToken(); numTokens++; if (mylog.isLoggable(Level.FINEST)) { mylog.log (Level.FINEST, " Token " + numTokens + " is: " + s2); } } } } ----------MyFileReader.java---------------------------------------------------------------------------------------- import java.io.*; import java.util.*; import java.util.logging.*; public class MyFileReader extends KeyboardReader { private static final Logger mylog = Logger.getLogger("samples.input.file"); public static void main (String[] args) throws java.io.IOException { String s1; String s2; // set up the buffered reader to read from the keyboard BufferedReader br = new BufferedReader (new FileReader ("MyFileReader.txt")); s1 = br.readLine(); if (mylog.isLoggable(Level.SEVERE)) { mylog.log (Level.SEVERE,"ATTN The line is " + s1); } if (mylog.isLoggable(Level.INFO)) { mylog.log (Level.INFO, "The line has " + s1.length() + " characters"); } if (mylog.isLoggable(Level.FINE)) { mylog.log (Level.FINE,"Breaking the line into tokens we get:"); } int numTokens = 0; StringTokenizer st = new StringTokenizer (s1); while (st.hasMoreTokens()) { s2 = st.nextToken(); numTokens++; if (mylog.isLoggable(Level.FINEST)) { mylog.log (Level.FINEST,"Breaking the line into tokens we get:"); mylog.log (Level.FINEST," Token " + numTokens + " is: " + s2); } } //end of while } // end of main } // end of class ----------MyFileReader.txt------------------------------------------------------------------------------------------ My first logging example -------logging.properties------------------------------------------------------------------------------------------- handlers= java.util.logging.ConsoleHandler, java.util.logging.FileHandler .level= FINEST java.util.logging.FileHandler.pattern = java%u.log java.util.logging.FileHandler.limit = 50000 java.util.logging.FileHandler.count = 1 java.util.logging.FileHandler.formatter = java.util.logging.SimpleFormatter java.util.logging.ConsoleHandler.level = FINEST java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter java.awt.focus.level=ALL ------Output log------------------------------------------------------------------------------------------- May 21, 2012 11:44:55 AM MyFileReader main SEVERE: ATTN The line is My first logging example May 21, 2012 11:44:55 AM MyFileReader main INFO: The line has 24 characters May 21, 2012 11:44:55 AM MyFileReader main FINE: Breaking the line into tokens we get: May 21, 2012 11:44:55 AM MyFileReader main FINEST: Breaking the line into tokens we get: May 21, 2012 11:44:55 AM MyFileReader main FINEST: Token 1 is: My May 21, 2012 11:44:55 AM MyFileReader main FINEST: Breaking the line into tokens we get: May 21, 2012 11:44:55 AM MyFileReader main FINEST: Token 2 is: first May 21, 2012 11:44:55 AM MyFileReader main FINEST: Breaking the line into tokens we get: May 21, 2012 11:44:55 AM MyFileReader main FINEST: Token 3 is: logging May 21, 2012 11:44:55 AM MyFileReader main FINEST: Breaking the line into tokens we get: May 21, 2012 11:44:55 AM MyFileReader main FINEST: Token 4 is: example Invocation command: "C:\Program Files (x86)\Java\jdk1.6.0_29\bin\java.exe" -Djava.util.logging.config.file=logging.properties MyFileReader References Further technical details are available here: http://docs.oracle.com/javase/1.4.2/docs/guide/util/logging/overview.html#1.0 http://docs.oracle.com/javase/1.4.2/docs/api/java/util/logging/package-summary.html http://www2.cs.uic.edu/~sloan/CLASSES/java/

  • Is measuring software project metrics popular in todays industry?

    - by Russ K
    I encountered a developer who wanted some outside advice on their teams project. I found out they're developing a huge software suite for the companies executives, project manager and developers that can calculate metrics automatically and graph them per iteration. As a student from a computer science background I know very little on metrics and their importance, but my questions are: Do most companies have some way, doesn't have to be an elegant program, to measure meaningful metrics? Which metrics, single or combined, help you narrow down your projects scope and estimates? As a person who analyzes metrics, how often do you base decisions off of them? IE. Tests failed per week is increasing drastically? Do you feel that the introduction of studying metrics has helped you understand the project better? Not sure why but the developers project intrigued me and I must know more. If y

  • Why prefer a wildcard to a type discriminator in a Java API (Re: Effective Java)

    - by Michael Campbell
    In the generics section of Bloch's Effective Java (which handily is the "free" chapter available to all: http://java.sun.com/docs/books/effective/generics.pdf), he says: If a type parameter appears only once in a method declaration, replace it with a wildcard. (See page 31-33 of that pdf) The signature in question is: public static void swap(List<?> list, int i, int j) vs public static void swap(List<E> list, int i, int j) And then proceeds to use a static private "helper" function with an actual type parameter to perform the work. The helper function signature is EXACTLY that of the second option. Why is the wildcard preferable, since you need to NOT use a wildcard to get the work done anyway? I understand that in this case since he's modifying the List and you can't add to a collection with an unbounded wildcard, so why use it at all?

Few organizations fully understand the impact projects have on their business. Consistently delivering successful projects is vital to the financial success of an asset intensive organization. Enterprise Project Portfolio Management (EPPM) is not a new concept yet for many organizations it is not considered "business critical". Webcast 1: Plan – Aligning project selection and prioritization with corporate objectives This webcast will look at 2 key questions: Are you aligning portfolio decisions with strategic objectives? How do you effectively measure the success of your portfolio decisions? Hear from Accenture who'll present a compelling case for why asset intensive organizations should consider EPPM as business critical. They'll explore: How technology is being used to enhance project delivery How collaboration enhances delivery performance The major challenges associated with the planning phase of a project Next hear from Geoff Roberts, Industry Strategist from Oracle Primavera. With over 30 years experience in project management/project controls in the construction, utilities and oil & gas sectors, Geoff will investigate how EPPM is a best practice and can support an organization through project selection and prioritization ensuring that decisions are aligned with corporate objectives.

  • What options do individual have to fork a project?

    - by skrco
    Let's assume our example individual has an idea, engagement, ... to fork project. By project I mean any kind of software - thick client, web site, portal, service, driver, plc, ... - anything that can be programmed. Motto of question: What options do our example individual have to fork this project from the early beginning through getting collaborators and users to mature software? Here are the main subquestions: Sandbox phase: Where can he announce his idea and proposal and receive positive/negative critic and feedback? Development phase: Where can he build his team to work on this project? Yet deployed phase: Where can he schedule tasks, assign tickets and bugs to be solved? and the list can go on... What really interests me is the "sandbox phase question".

  • I am getting an error with a oneToMany association when using annotations with gilead for hibernate

    - by user286630
    Hello Guys I'm using Gilead to persist my entities in my GWT project, im using hibernate annotations aswell. my problem is on my onetomany association.this is my User class that holds a reference to a list of FileLocations @Entity @Table(name = "yf_user_table") public class YFUser implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "user_id",nullable = false) private int userId; @Column(name = "username") private String username; @Column(name = "password") private String password; @Column(name = "email") private String email; @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY) @JoinColumn(name="USER_ID") private List fileLocations = new ArrayList(); This is my file location class @Entity @Table(name = "fileLocationTable") public class FileLocation implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "locationId", updatable = false, nullable = false) private int ieId; @Column (name = "location") private String location; @ManyToOne(fetch=FetchType.LAZY) @JoinColumn(name="USER_ID", nullable=false) private YFUser uploadedUser; When i persist this data in a normal desktop application, it works fine , creates the tables and i can add and store data to it. but when i try to persist the data in my gwt application i get errors i will show them lower. this is my ServiceImpl class that extends PersistentRemoteService. public class TestServiceImpl extends PersistentRemoteService implements TestService { public static final String SESSION_USER = "UserWithinSession"; public TestServiceImpl(){ HibernateUtil util = new HibernateUtil(); util.setSessionFactory(com.example.server.HibernateUtil .getSessionFactory()); PersistentBeanManager pbm = new PersistentBeanManager(); pbm.setPersistenceUtil(util); pbm.setProxyStore(new StatelessProxyStore()); setBeanManager(pbm); } @Override public String registerUser(String username, String password, String email) { Session session = com.example.server.HibernateUtil.getSessionFactory().getCurrentSession(); session.beginTransaction(); YFUser newUser = new YFUser(); newUser.setUsername(username);newUser.setPassword(password);newUser.setEmail(email); session.save(newUser); session.getTransaction().commit(); return "Thank you For registering "+ username; } this is the error that im am getting. the error goes away when i remove my onetoManyRelationship and builds my session factory when i put it in , it on the line of buildsessionfactory in hibernate Util that it throws this exception. my hibernate util class is ok also. this is the error java.lang.NoSuchMethodError: javax.persistence.OneToMany.orphanRemoval()Z Mar 24, 2010 10:03:22 PM org.hibernate.cfg.annotations.Version <clinit> INFO: Hibernate Annotations 3.5.0-Beta-4 Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Environment <clinit> INFO: Hibernate 3.5.0-Beta-4 Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Environment <clinit> INFO: hibernate.properties not found Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Environment buildBytecodeProvider INFO: Bytecode provider name : javassist Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Environment <clinit> INFO: using JDK 1.4 java.sql.Timestamp handling Mar 24, 2010 10:03:22 PM org.hibernate.annotations.common.Version <clinit> INFO: Hibernate Commons Annotations 3.2.0-SNAPSHOT Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Configuration configure INFO: configuring from resource: /hibernate.cfg.xml Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Configuration getConfigurationInputStream INFO: Configuration resource: /hibernate.cfg.xml Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Configuration doConfigure INFO: Configured SessionFactory: null Mar 24, 2010 10:03:22 PM org.hibernate.cfg.search.HibernateSearchEventListenerRegister enableHibernateSearch INFO: Unable to find org.hibernate.search.event.FullTextIndexEventListener on the classpath.

In this plugin i am using reflection to execute a function in a class present in another project which is a hibernate project.Whenever the invoke is used i.e mymethod.invoke(myobj); it is giving this exception java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:37) at java.lang.reflect.Method.invoke(Method.java:599) at packagesearch.DummyExecution.execution(DummyExecution.java:154) at packagesearch.HelloWorldAction.run(HelloWorldAction.java:48) at org.eclipse.ui.internal.PluginAction.runWithEvent(PluginAction.java:251) at org.eclipse.ui.internal.WWinPluginAction.runWithEvent(WWinPluginAction.java:229) at org.eclipse.jface.action.ActionContributionItem.handleWidgetSelection(ActionContributionItem.java:583) at org.eclipse.jface.action.ActionContributionItem.access$2(ActionContributionItem.java:500) at org.eclipse.jface.action.ActionContributionItem$6.handleEvent(ActionContributionItem.java:452) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1003) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3823) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3422) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2384) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2348) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2200) at org.eclipse.ui.internal.Workbench$5.run(Workbench.java:495) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:288) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:490) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:113) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:193) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:386) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:37) at java.lang.reflect.Method.invoke(Method.java:599) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:549) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:504) at org.eclipse.equinox.launcher.Main.run(Main.java:1236) at org.eclipse.equinox.launcher.Main.main(Main.java:1212) Caused by: java.lang.NoClassDefFoundError: org.dom4j.DocumentException at java.lang.J9VMInternals.verifyImpl(Native Method) at java.lang.J9VMInternals.verify(J9VMInternals.java:72) at java.lang.J9VMInternals.initialize(J9VMInternals.java:134) at test.Example.demo1(Example.java:38) ... 36 more Caused by: java.lang.ClassNotFoundException: org.dom4j.DocumentException at java.net.URLClassLoader.findClass(URLClassLoader.java:419) at java.lang.ClassLoader.loadClass(ClassLoader.java:643) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:345) at java.lang.ClassLoader.loadClass(ClassLoader.java:609) ... 40 more what is the exact problem . i have used loader to load the class.Help

  • Yet another Java classpath problem

    - by pypmannetjies
    Hi I've been working on a project in Netbeans. Now I'd like to submit it and allow the markers to compile it with a script. However, I get the NoClassDefFoundError when I try to run via the command line. Even when setting the classpath to the current directory manually. javac Main.java works fine then calling java -classpath . Main gives: java -classpath .

  • JPA/Hibernate Embedded id

    - by RoD
    I would like to do something like that: An object ReportingFile that can be a LogRequest or a LogReport file. ( both got the same structure) An object Reporting containing for one logRequest, a list of logReport with a date. I tryed to set an EmbededId, that would be an attribute of the logRequest. And that's the problem i got. I don't arrive to mannage embedded id. ( http://docs.jboss.org/hibernate/stable/annotations/reference/en/html_single/#entity-mapping-identifier ) If you have a clue on how i should do it :) An example (not working) would be: @Entity @AssociationOverride( name="logRequest.fileName", joinColumns = { @JoinColumn(name="log_request_file_name") } ) public class Reporting { @EmbeddedId private ReportingFile logRequest; @CollectionOfElements(fetch = FetchType.EAGER) @JoinTable(name = "t_reports", schema="", joinColumns = {@JoinColumn(name = "log_report")}) @Fetch(FetchMode.SELECT) private List<ReportingFile> reports; @Column(name="generated_date",nullable=true) private Date generatedDate; [...] } @Embeddable public class ReportingFile { @Column(name="file_name",length=255) private String fileName; @Column(name="xml_content") private Clob xmlContent;

  • Using Java Executor on AppEngine causes AccessControlException

    - by Drew
    How do you get java.util.concurrent.Executor or CompletionService to work on Google AppEngine? The classes are all officially white-listed, but I get a runtime security error when trying to submit asynchronous tasks. Code: // uses the async API but this factory makes it so that tasks really // happen sequentially Executor executor = java.util.concurrent.Executors.newSingleThreadExecutor(); // wrap Executor in CompletionService CompletionService<String> completionService = new ExecutorCompletionService<String>(executor); final SomeTask someTask = new SomeTask(); // this line throws exception completionService.submit(new Callable<String>(){ public String call() { return someTask.doNothing("blah"); } }); // alternately, send Runnable task directly to Executor, // which also throws an exception executor.execute(new Runnable(){ public void run() { someTask.doNothing("blah"); } }); } private class SomeTask{ public String doNothing(String message){ return message; } } Exception: java.security.AccessControlException: access denied (java.lang.RuntimePermission modifyThreadGroup) at java.security.AccessControlContext.checkPermission(AccessControlContext.java:323) at java.security.AccessController.checkPermission(AccessController.java:546) at java.lang.SecurityManager.checkPermission(SecurityManager.java:532) at com.google.appengine.tools.development.DevAppServerFactory$CustomSecurityManager.checkPermission(DevAppServerFactory.java:166) at com.google.appengine.tools.development.DevAppServerFactory$CustomSecurityManager.checkAccess(DevAppServerFactory.java:191) at java.lang.ThreadGroup.checkAccess(ThreadGroup.java:288) at java.lang.Thread.init(Thread.java:332) at java.lang.Thread.(Thread.java:565) at java.util.concurrent.Executors$DefaultThreadFactory.newThread(Executors.java:542) at java.util.concurrent.ThreadPoolExecutor.addThread(ThreadPoolExecutor.java:672) at java.util.concurrent.ThreadPoolExecutor.addIfUnderCorePoolSize(ThreadPoolExecutor.java:697) at java.util.concurrent.ThreadPoolExecutor.execute(ThreadPoolExecutor.java:652) at java.util.concurrent.Executors$DelegatedExecutorService.execute(Executors.java:590) at java.util.concurrent.ExecutorCompletionService.submit(ExecutorCompletionService.java:152) This code works fine when run on Tomcat or via command-line JVM. However, it chokes in the AppEngine SDK Jetty container (tried with Eclipse plugin and the maven-gae-plugin). AppEngine is likely designed to not allow potentially dangerous programs to run, so I could see them completely disabling thread creation. However, why would Google allow you to create a class, but not allow you to call methods on it? White-listing java.util.concurrent is misleading. Is there some other way to do parallel/simultaneous/concurrent tasks on GAE?

  • Choosing between PHP and Java

    - by user996459
    I've recently started University, studying Computing and IT. My Uni focuses on Java. My study will consist of mathematics, 'boring' IT related stuff and several Java units such as: -Software development with Java, -Object-oriented Java programming, -Relational databases: theory and practice (using Java), -Developing concurrent distributed systems (using Java), -Software engineering with objects (using Java). I'm trying to determine whenever I should focus on Java and self study it in my free time so that I can actually learn and become a competent Java programmer by the time I graduate, or, only do enough Java to get the degree but in my free time self study PHP and related web technologies. Job market in my area appears to be balanced for the two, salary and availability wise. Regardless of which patch I'd take getting a job should not be a problem however Java does seem to pay almost insignificantly more. In terms of my interest and career expectations, I don't have anything specific planned. I very much enjoy writing code but I don't really care what kind. So far I equally enjoyed writing C, AutoIT, vb.net, PHP and even Java. Basically, I'm happy as long as I get to type in code (be it low level programming or web back-end scripting). So the question really is, would my Uni and their Java focus profit me should I choose PHP? Or should I buy what my university is selling and stick to Java like a fly sticks to poop...? Apologies for cryptic writing, still learning English

  • Safe project development - free repositories

    - by friko
    Some time ago we started a private hobby project. We made a project on javaforge.com, created an svn repository and started developing our app. Right now we are really far with our project, but somehow we never worried if our project is really safe on such free development tool like javaforge ? I mean, what if our project would earn some money and the source code become valuable ? Could it be stolen or could somebody take it over ? We want to be sure that we are not wasting our time and want to be really sure about our project safety. Is it possible to safely develop a project in such free repository ? We would like also to start using redmine, so if you know any safe place for moving our project, please take this under consideration. Thanks a lot.

  • Getting NoClassdef on HMAC_SHA1 in Webpshere

    - by defjab
    We have WAS 6.0 (I know) .2.43 ND running in multiple regions. Our Dev-B region runs fine, but Dev-C throws a java exception when we make web-calls (at least this is what the developer tells me)...Same code in both regions and I checked the obvious suspects (Global security, SSL ciphers etc) and they all seem to match. Here's the stack trace from SystemErr: [8/1/12 4:02:31:758 EDT] 0000005c ServletWrappe E SRVE0068E: Could not invoke the service() method on servlet action.

  • Error in loading component property (Swing GUI Forms)

    - by Christo Du Preez
    For no apparent reason all my Swing GUI forms using components linked to org.jdesktop.beansbinding.Converter started generating errors when trying to open the Design View: Error Error in loading component property: [JPanel]-filterTextField-converter. Cannot load property type class org.jdesktop.beansbinding.Converter. The property cannot be loaded. Errors occurred in loading... I'm currently using Netbeans 6.8. I opened my project in Netbeans 6.7.1 and all was fine but after a while the same thing happened. Looking at the .form and .java files and comparing it to previous backups, everything looks fine. Even my Netbeans tutorial project no longer works. What can cause this. Any suggestions would greatly be appreciated. After further investigation this is taken from my IDE's log : INFO: msg org.openide.ErrorManager$AnnException: msg at org.openide.ErrorManager$AnnException.findOrCreate(ErrorManager.java:867) at org.openide.ErrorManager$DelegatingErrorManager.annotate(ErrorManager.java:650) at org.netbeans.modules.form.GandalfPersistenceManager.annotateException(GandalfPersistenceManager.java:230) at org.netbeans.modules.form.GandalfPersistenceManager.annotateException(GandalfPersistenceManager.java:240) at org.netbeans.modules.form.GandalfPersistenceManager.getPropertyType(GandalfPersistenceManager.java:2362) at org.netbeans.modules.form.GandalfPersistenceManager.loadProperty(GandalfPersistenceManager.java:2041) at org.netbeans.modules.form.GandalfPersistenceManager.loadBindingProperties(GandalfPersistenceManager.java:2627) at org.netbeans.modules.form.GandalfPersistenceManager.loadComponent(GandalfPersistenceManager.java:900) at org.netbeans.modules.form.GandalfPersistenceManager.restoreComponent(GandalfPersistenceManager.java:845) at org.netbeans.modules.form.GandalfPersistenceManager.loadComponent(GandalfPersistenceManager.java:979) at org.netbeans.modules.form.GandalfPersistenceManager.restoreComponent(GandalfPersistenceManager.java:845) at org.netbeans.modules.form.GandalfPersistenceManager.loadNonVisuals(GandalfPersistenceManager.java:695) at org.netbeans.modules.form.GandalfPersistenceManager.loadForm(GandalfPersistenceManager.java:529) at org.netbeans.modules.form.GandalfPersistenceManager.loadForm(GandalfPersistenceManager.java:290) at org.netbeans.modules.form.FormEditor$3.run(FormEditor.java:339) at org.netbeans.modules.form.FormLAF$2.run(FormLAF.java:287) at org.openide.util.Mutex.doEventAccess(Mutex.java:1355) at org.openide.util.Mutex.readAccess(Mutex.java:317) at org.netbeans.modules.form.FormLAF.executeWithLookAndFeel(FormLAF.java:272) at org.netbeans.modules.form.FormEditor.loadFormData(FormEditor.java:337) at org.netbeans.modules.form.FormEditor.loadForm(FormEditor.java:266) at org.netbeans.modules.form.FormEditorSupport.loadForm(FormEditorSupport.java:306) at org.netbeans.modules.form.FormEditorSupport$3.run(FormEditorSupport.java:457) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:209) at java.awt.EventQueue.dispatchEvent(EventQueue.java:597) at org.netbeans.core.TimableEventQueue.dispatchEvent(TimableEventQueue.java:125) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:269) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:184) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:174) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:169) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:161) at java.awt.EventDispatchThread.run(EventDispatchThread.java:122) Caused by: java.lang.ClassNotFoundException: Will not load class org.jdesktop.beansbinding.Converter arbitrarily from one of ModuleCL@738d08[org.jdesktop.beansbinding] and ModuleCL@167e3a5[javax.beans.binding] starting from SystemClassLoader[556 modules]; see http://wiki.netbeans.org/DevFaqModuleCCE at org.netbeans.ProxyClassLoader.loadClass(ProxyClassLoader.java:241) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at org.netbeans.modules.form.project.FormClassLoader.findClass(FormClassLoader.java:83) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:247) at org.netbeans.modules.form.project.ClassPathUtils.loadClass(ClassPathUtils.java:95) at org.netbeans.modules.form.FormUtils.loadClass(FormUtils.java:1445) at org.netbeans.modules.form.PersistenceObjectRegistry.loadClass(PersistenceObjectRegistry.java:95) at org.netbeans.modules.form.GandalfPersistenceManager.getClassFromString(GandalfPersistenceManager.java:5516) at org.netbeans.modules.form.GandalfPersistenceManager.getPropertyType(GandalfPersistenceManager.java:2348) ... 27 more msg Error in loading component property: Other Components-mainPanel-jTextField1-converter Cannot load property type class org.jdesktop.beansbinding.Converter.

  • Assigning resources to MS Project 2007

    - by adam
    Hi, I'm planning a redesign of a site in Project 2007. I have three developers to hand, all with the same skills. There are about 80 templates to be rendered as part of the redesign, and each template has been added as a project task. Each of these tasks can be done by any of the 3 devs, and each will take a day (with a few exceptions). There is no order in which the tasks must be completed, so there are no predecessor rules. I'd like to be able to assign tasks to a 'Developer' resource group, and for Project to see that three tasks can be done at once (as the group has three resources members) and queue the tasks as such. Googling leads me to Team Assignment, but that appears to be part of Project Server. Surely I can do this in standalone Project? Thanks, Adam
