  • Are application servers necessary? Advantages of using one? (And other JEE questions)

    - by Mike
    Apologies for the long question.. there seems to be other similar questions on here but none really clear up my confusion. I'd be really grateful if someone could confirm or correct my understanding: Java Enterprise Edition is a set of APIs for building enterprise applications, which take away the burden of developing parts of the system that aren't actually features of the application you are trying to build (i.e. messaging, transactions etc). To do this, you can use an application server, which implements these APIs. So you could use JBoss, Glassfish, WebSphere, WebLogic etc which would provide your application with these enterprise services. However, there are many other implementations of these individual services available such as ActiveMQ for messaging, Hibernate for persistence, OpenEJB etc. You can download these implementations as Java libraries and include them in your application, and use the services they provide in a similar way to using the services provided by an application server. So if my understanding is correct, my questions are: I've read a lot of places that application servers are necessary for JEE features like EJB, but can't you just use an implementation such as OpenEJB and not need an application server at all? Are there any features that an application server provides which you cannot get from another source? Why would/wouldn't I choose an application server over a custom stack such as Tomcat, OpenEJB, ActiveMQ, and Hibernate? Is Spring a complete alternative to JEE? Does it ever require an application server or always just a servlet container? Why would someone choose Spring over JEE? Any help would be much appreciated!

  • Ability to switch Persistence Unit dynamically within the application (JPA)

    - by MVK
    My application data access layer is built using Spring and EclipseLink and I am currently trying to implement the following feature - Ability to switch the current/active persistence unit dynamically for a user. I tried various options and finally ended up doing the following. In the persistence.xml, declare multiple PUs. Create a class with as many EntityManagerFactory attributes as there are PUs defined. This will act as a factory and return the appropriate EntityManager based on my logic public class MyEntityManagerFactory { @PersistenceUnit(unitName="PU_1") private EntityManagerFactory emf1; @PersistenceUnit(unitName="PU_2") private EntityManagerFactory emf2; public EntityManager getEntityManager(int releaseId) { // Logic goes here to return the appropriate entityManeger } } My spring-beans xml looks like this.. <!-- First persistence unit --> <bean class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" id="emFactory1"> <property name="persistenceUnitName" value="PU_1" /> </bean> <bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager1"> <property name="entityManagerFactory" ref="emFactory1"/> </bean> <tx:annotation-driven transaction-manager="transactionManager1"/> The above section is repeated for the second PU (with names like emFactory2, transactionManager2 etc). I am a JPA newbie and I know that this is not the best solution. I appreciate any assistance in implementing this requirement in a better/elegant way! Thanks!

  • How to find all initializations of instance variables in a Java package?

    - by Hank Gay
    I'm in the midst of converting a legacy app to Spring. As part of the transition, we're converting our service classes from an "instantiate new ones whenever you need one" style to a Springleton style, so I need a way to make sure they don't have any state. I'm comfortable on the *nix command-line, and I have access to IntelliJ (this strikes me as a good fit for Structural Search and Replace, if I could figure out how to use it), and I could track down an Eclipse install, if that would help. I just want to make absolutely sure I've found all the possible problems. UPDATE: Sorry for the confusion. I don't have a problem finding places where the old constructor was being called. What I'm looking for is a "bullet-proof" why to search all 100+ service classes for any sort of internal state. The most obvious one I could think of (and the only one I've really found so far) is cases where we use memoization in the classes, so they have instance variables that get initialized internally instead of via Spring. This means that when the same Springleton gets used for different requests, data can leak between them. Thanks.

  • What would be a better implementation of shared variable among subclass

    - by Churk
    So currently I have a spring unit testing application. And it requires me to get a session cookie from a foreign authentication source. Problem what that is, this authentication process is fairly expensive and time consuming, and I am trying to create a structure where I am authenticate once, by any subclass, and any subsequent subclass is created, it will reuse this session cookie without hitting the authentication process again. My problem right now is, the static cookie is null each time another subclass is created. And I been reading that using static as a global variable is a bad idea, but I couldn't think of another way to do this because of Spring framework setting things during run time and how I would set the cookie so that all other classes can use it. Another piece of information. The variable is being use, but is change able during run time. It is not a single user being signed in and used across the board. But more like a Sub1 would call login, and we have a cookie. Then multiple test will be using that login until SubX will come in and say, I am using different credential, so I need to login as something else. And repeats. Here is a outline of my code: public class Parent implements InitializingBean { protected static String BASE_URL; public static Cookie cookie; ... All default InitializingBean methods ... afterPropertiesSet() { cookie = // login process returns a cookie } } public class Sub1 extends Parent { @resource public String baseURL; @PostConstruct public void init() { // set parents with my baseURL; BASE_URL = baseURL; } public void doSomething() { // Do something with cookie, because it should have been set by parent class } } public class Sub2 extends Parent { @resource public String baseURL; @PostConstruct public void init() { // set parents with my baseURL; BASE_URL = baseURL; } public void doSomethingElse() { // Do something with cookie, because it should have been set by parent class } }

  • How to model and handle presentation DTO's to abstract from complicated domain model?

    - by arrages
    Hi I am developing an application that needs to work with a complex domain model using Hibernate. This application uses Spring MVC and using the domain objects in the presentation layer is very messy so I think I should use DTO's that go to and from my service layer so that these match what I need in my views. Now lets assume I have a CarLease entity whose properties are not simple java primitives but it's composed with other entities like Make, Model, etc public class CarLease { private Make make; Private Model model; . . . } most properties are in this fashion and they are selectable using drop down selects on the jsp view, each will post back an ID to the controller. Now considering some standard use cases: create, edit, display How would you go about modeling the presentation DTO's to be used as form backing objects and communication between presentation and service layers?? Would you create a different DTO for each case (create, edit, display), would you make DTO's for the complex attributes? if so where would you translate the ID to entity? how and where would you handle validation, DTO/Domain assembly, what would you return from service layer methods? (create, edit, get) As you can see, I now I will benefit by separating my view from the domain objects (very complex with lots of stuff I don't need.) but I am having a hard time finding any real world examples and best practices for this. I need some architecture guidance from top to bottom, please keep in mind I will use Spring MVC in case that may leverage on your anwser. thanks in advance.

  • Job queueing and execute Mechanism

    - by Calm Storm
    In my webservice all method calls submits jobs to a queue. Basically these operations take long time to execute, so all these operations submit a Job to a queue and return a status saying "Submitted". Then the client keeps polling using another service method to check for the status of the job. Presently, what I do is create my own Queue, Job classes that are Serializable and persist these jobs (i.e, their serialized byte stream format) into the database. So an UpdateLogistics operation just queues up a "UpdateLogisticsJob" to the queue and returns. I have written my own JobExecutor which wakes up every N seconds, scans the database table for any existing jobs, and executes them. Note the jobs have to persisted because these jobs have to survive app-server crashes. This was done a long time ago, and I used bespoke classes for my Queues, Jobs, Executors etc. But now, I would like to know has someone done something similar before? In particular, Are there frameworks available for this ? Something in Spring/Apache etc Any framework that is easy to adapt/debug and plays well along with libraries like Spring will be great.

  • best way to avoid sql injection

    - by aauser
    I got similar domain model 1) User. Every user got many cities. @OneToMany(targetEntity=adv.domain.City.class...) 2) City. Every city got many districts @OneToMany(targetEntity=adv.domain.Distinct.class) 3) Distintc My goal is to delete distinct when user press delete button in browser. After that controller get id of distinct and pass it to bussiness layer. Where method DistinctService.deleteDistinct(Long distinctId) should delegate deliting to DAO layer. So my question is where to put security restrictions and what is the best way to accomplish it. I want to be sure that i delete distinct of the real user, that is the real owner of city, and city is the real owner of distinct. So nobody exept the owner can't delete ditinct using simple url like localhost/deleteDistinct/5. I can get user from httpSession in my controller and pass it to bussiness layer. After that i can get all cities of this user and itrate over them to be sure, that of the citie.id == distinct.city_id and then delete distinct. But it's rather ridiculous in my opinion. Also i can write sql query like this ... delete from t_distinct where t_distinct.city_id in (select t_city.id from t_city left join t_user on t_user.id = t_city.owner_id where t_user.id = ?) and t_distinct.id = ? So what is the best practice to add restrictions like this. I'm using Hibernate, Spring, Spring MVC by the way.. Thank you

  • How to set the ActiveMQ redeliveryPolicy on a queue?

    - by edbras
    How do I set the redeliveryPolicy in ActiveMQ on a Queue? 1) In the doc, see: activeMQ Redelivery, the explain that you should set it on the ConnectionFactory or Connection. But I want to use different value's for different Queue's. 2) Apart from that, I don't seem to get it work. Setting it on the connection factory in Spring (I am using activemq 5.4.2. with Spring 3.0) like this don't seem to have any effect: <amq:connectionFactory id="amqConnectionFactory" brokerURL="${jms.factory.url}" > <amq:properties> <amq:redeliveryPolicy maximumRedeliveries="6" initialRedeliveryDelay="15000" useExponentialBackOff="true" backOffMultiplier="5"/> </amq:properties> </amq:connectionFactory> I also tried to set it as property on the defined Queue, but that also seem to be ignored as the redelivery occurs sooner that the defined values: <amq:queue id="jmsQueueDeclarationSnd" physicalName="${jms.queue.declaration.snd}" > <amq:properties> <amq:redeliveryPolicy maximumRedeliveries="6" initialRedeliveryDelay="15000" useExponentialBackOff="true" backOffMultiplier="5"/> </amq:properties> </amq:queue> Thanks

  • Choose 'better' or more familiar technologies for a new project?

    - by John
    I am looking to start work on a brand-new project, something I've been thinking about for a while as my first independent sellable project. It's broadly speaking a web-based service application, and my first choice, server-language is quite easy... I know Java pretty well from working on Java web-apps in the past. However my experience doing web-apps involved JSP, Servlets and JSTL... I know the ideas behind newer technologies like Hibernate/Spring but have never used them. So we wrote our own DAOs, handled AJAX by writing special mini-JSP pages that generated XML/JSON pages, etc. I'm not hugely into the idea that Spring/Hibernate are the 'only' or 'right' way to do any Java web-project, but they are widely used. On the other hand, not only would trying to learn these increase initial development time, but I'd be using my learning attempts to build a production system. I remember one of Joel's early articles said (I'll paraphrase since I can't find it) "regardless what's cool, always use the technologies that the lead developer (or dev team?) knows best" I wondered what people thought about that? ps: should this be CW?

  • How to configure Spring JavaMailSenderImpl for Gmail

    - by Andrew Carlson
    I am trying to find the correct properties to use to connect to the Gmail SMTP sever using the JavaMailSenderImpl class. Let me first say that I have tried the approach found here. This worked fine. But when I tried the configuration below that post with the exact same authentication information I received a javax.mail.AuthenticationFailedException. My currently configuration looks like this. <bean id="mailSender" class ="org.springframework.mail.javamail.JavaMailSenderImpl" > <property name="username" value="[email protected]" /> <property name="password" value="XXX" /> <property name="javaMailProperties"> <props> <prop key="mail.smtp.host">smtp.gmail.com</prop> <prop key="mail.smtp.port">587</prop> <prop key="mail.smtp.auth">true</prop> <prop key="mail.smtp.starttls.enable">true</prop> </props> </property> </bean> Why am I still getting this javax.mail.AuthenticationFailedException if I know that my credentials are correct. Update Here is my updated code based on the answers below. I am still receiving the same exception. <bean id="mailSender" class ="org.springframework.mail.javamail.JavaMailSenderImpl" > <property name="username" value="[email protected]" /> <property name="password" value="XXX" /> <property name="javaMailProperties"> <props> <prop key="mail.smtp.from">[email protected]</prop> <prop key="mail.smtp.user">[email protected]</prop> <prop key="mail.smtp.password">XXX</prop> <prop key="mail.smtp.host">smtp.gmail.com</prop> <prop key="mail.smtp.port">587</prop> <prop key="mail.smtp.auth">true</prop> <prop key="mail.smtp.starttls.enable">true</prop> </props> </property> </bean>

  • Why can't I retrieve the entities I've just persisted?

    - by felipecao
    I've got this web service that basically queries the database and returns all persisted entities. For testing purposes, I've created a TestDataManager that persists 2 example entities after Spring context is loaded (BTW, I'm using JAX-WS, Spring, Hibernate and HSQLDB). My TestDataManager looks like this: @Component public class TestDataManager { @Resource private SessionFactory sf; @PostConstruct @Transactional(readOnly = false, propagation = Propagation.REQUIRES_NEW) public void insertTestData(){ sf.openSession(); sf.openSession().beginTransaction(); sf.openSession().persist(new Site("site one")); sf.openSession().persist(new Site("site two")); sf.openSession().flush(); } } My JAX-WS endpoint looks like this: @WebService public class SmartBrickEndpoint { @Resource private WebServiceContext context; public Set<Site> getSitesForUser(String user){ return getSiteService().findByUser(new User(user)); } private ISiteService getSiteService(){ ServletContext servletContext = (ServletContext) context.getMessageContext().get("javax.xml.ws.servlet.context"); return (ISiteService) BeanRetriever.getBean(servletContext, ISiteService.class); } } This my Service class: @Component @Transactional(readOnly = true) public class SiteService implements ISiteService { @Resource private ISiteDao siteDao; @Override public Set<Site> findByUser(User user) { return siteDao.findByUser(user); } } This is my DAO: @Component @Transactional(readOnly = true) public class SiteDao implements ISiteDao { @Resource private SessionFactory sessionFactory; @Override public Set<Site> findByUser(User user) { Set<Site> sites = new LinkedHashSet<Site>(sessionFactory.getCurrentSession().createCriteria(Site.class).list()); return sites; } } This is my applicationContext.xml: <context:annotation-config /> <context:component-scan base-package="br.unirio.wsimxp.dao"/> <context:component-scan base-package="br.unirio.wsimxp.service"/> <context:component-scan base-package="br.unirio.wsimxp.spring"/> <bean id="applicationDS" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="org.hsqldb.jdbcDriver"/> <property name="url" value="jdbc:hsqldb:file:sites"/> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="dataSource" ref="applicationDS" /> <property name="configLocation"> <value>classpath:hibernate.cfg.xml</value> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.HSQLDialect</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.format_sql">true</prop> <prop key="hibernate.connection.release_mode">on_close</prop> <!--<prop key="hibernate.current_session_context_class">thread</prop>--> <prop key="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</prop> <prop key="hibernate.hbm2ddl.auto">create-drop</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" /> This is what's going on now: when the app is deployed, TestDataManager#insertTestData kicks-in (due to @PostConstruct) and persist does not raise any exception. I should have 2 entities in the DB by now. Afterwards, I invoke the endpoint by a SOAP client, and the request goes all the way up to the DAO. The Hibernate invocation does not raise any exception, but the returned list is empty. The odd thing is, in TestDataManager, if I switch from sf.openSession() to sf.getCurrentSession(), I get an error message: "No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here". What I am doing wrong here? Why is the query "not seeing" the persisted entities? Why do I need to invoke sf.openSession() on TestDataManager although it's annotated with @Transactional? I have done some tests with hibernate.current_session_context_class=thread in application.xml, but then I just switch problems in each class. I'd like not needing to manually invoke sf.openSession() and leave that for Hibernate to take care. Thanks a lot for any help!

  • JNDI Issues: Jboss 4.2.2 Spring 2.5 and hibernate ejb

    I have a strange problem, that is causing me some grief. If the following jar is in my classpath: <dependency> <groupId>org.hibernate</groupId> <artifactId>org.hibernate.ejb</artifactId> <version>3.3.2.GA</version> </dependency> My JNDI lookup for my datasource returns null. Here is the basic code I am using to do the lookup: InitialDirContext ctx = new InitialDirContext(env); DataSource dataSource = (DataSource)ctx.lookup("java:dataContent"); Otherwise, the DataSource returns fine from the context. Unfortunately, I need the jar in order to avoid ClassCastExceptions within Jboss 4.2.2. Any help is appreciated.
