• 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.

• 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;

• 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

• 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.

This is still not resolved and not being able to edit my Forms or loosing binding properties every time I need to edit a Form is a real pain and time consuming! Any help would greatly be appreciated. Thanx.

• RPi and Java Embedded GPIO: Sensor Connections for Java Enabled Interface

  - by hinkmond

  Now we're ready to connect the hardware needed to make a static electricity sensor for the Raspberry Pi and use Java code to access it through a GPIO port. First, very carefully bend the NTE312 (or MPF-102) transistor "gate" pin (see the diagram on the back of the package or refer to the pin diagram on the Web). You can see it in the inset photo on the bottom left corner. I bent the leftmost pin of the NTE312 transistor as I held the flat part toward me. That is going to be your antenna. So, connect one of the jumper wires to the bent pin. I used the dark green jumper wire (looks almost black; coiled at the bottom) in the photo. Then push the other 2 pins of the transistor into your breadboard. Connect one of the pins to Pin # 1 (3.3V) on the GPIO header of your RPi. See the diagram if you need to glance back at it. In the photo, that's the orange jumper wire. And connect the final unconnected transistor pin to Pin # 22 (GPIO25) on the RPi header. That's the blue jumper wire in my photo. For reference, connect the LED anode (long pin on a common anode LED/short pin on a common cathode LED, check your LED pin diagram) to the same breadboard hole that is connecting to Pin # 22 (same row of holes where the blue wire is connected), and connect the other pin of the LED to GROUND (row of holes that connect to the black wire in the photo). Test by blowing up a balloon, rubbing it on your hair (or your co-worker's hair, if you are hair-challenged) to statically charge it, and bringing it near your antenna (green wire in the photo). The LED should light up when it's near and go off when you pull it away. If you need more static charge, find a co-worker with really long hair, or rub the balloon on a piece of silk (which is just as good but not as fun). Next blog post is where we do some Java coding to access this sensor on your RPi. Finally, back to software! Ha! Hinkmond

• Oracle Java Cloud Service - Platform as a Service for Your Java Applications

  - by GeneEun

  Oracle Java Cloud Service is an enterprise grade Platform as a Service for developing, testing, and deploying business applications. For Java developers, Java Cloud Service provides the power, flexibility, and performance of a true Java EE container in the cloud. Java Cloud Service delivers one of the key advantages of the Java platform, the ability to “write once, run anywhere”. Because of the standards-based approach, there's no need to worry that applications you build and deploy are forever locked into the Oracle Cloud.  In fact, you can use Java Cloud Service just as you would an on-premise Java EE environment and deploy your Java applications on a Java Cloud Service instance as-is. Provisioning of Java Cloud Service instances is self-service and takes only minutes, making access to Java environments both quick and easy. Java Cloud Service instances are also automatically associated with Oracle Database Cloud Service instances, so there's no complex setup involved in order to get a complete application environment up and running.If you're attending Oracle OpenWorld in San Francisco this week, I'm sure you've seen that there are many sessions covering Oracle Cloud services, including Java Cloud Service. Each session will provide a wealth of information, so I highly recommend you consult your conference schedule and try to check them out. In the meantime, here's a short video about Java Cloud Service. Enjoy!

• Site/Project to convert in Java web pages as it is now with complete functionality, look and feel.

  - by pirzada

  I have completed a web site Surfrainbow using ASP.NET and working fine. Completely dynamic with back-end management and Ajax support. This site has to be 100% same as in Java considering look and feel. Conversion is for learning purpose. I am new to Java and learning it fast. I don't want to know how to learn Java. Just want to know what is needed for this project to work in Java related technologies. Want to know How would you handle this project. My questions are 1 - What technologies I will be needing to make this project like Servlets, JSP, JSF etc? 2 - What is needed for Ajax support. Is JQuery supported :)? 3 - What should be used for MVC? 4 - ASP.NET has master pages to simplify design. Anything like this in Java? 5 - Which IDE is best for Java development. JDeveloper/NetBeans? Anything else you can share. Thanks
