• Hibernate proxy serialization and receive on client side.

  - by Bubba88

  I lack understanding of how does the generated proxy class object (CGLib enhanced POJO) is transferred to the remote client and still pertains its ability to generate Lazy Init. Exceptions. Does that mean that there is some kind of contract that all the transferred objects of some kind of class (a proxy) will be reinstantiated as proxies again? Where does the client obtain those generated classes? Sorry, but I totally do not understand.

• Can I specify to Castle Windsor which virtual methods to override in a class proxy?

  - by Thiado de Arruda

  I have many virtual methods in a class, but only one should be intercepted, Can I tell Castle Windsor to override only that method so I dont have to do validation in the Intercept method? Edit: I use the IKernelEvents.ComponentRegistered event to choose which types get the interceptor.

• How can I dynamically inject code to event handlers in Delphi?

  - by mjustin

  For debugging / performance tests I would like to dynamically add logging code to all event handlers of components of a given type. For example, for all Dataset components located ona TDatamodule, I would like to add some code for the BeforeOpen and the AfterOpen event to store the start and end time and send a line to a logger with the elapsed time in the AfterOpen event. I would prefer to do this dynamically (no component subclassing), so that I can add this to all existing datamodules and forms with minimal effort only when needed. Iterating all components and filtering by their type is easy, but for the components which already have event handlers assigned, I need a way to store the existing event handlers, and assign a new modified event handler which first does the logging and then will invoke the original code which was already present. Is there a design pattern which can be applied, or even some example code which shows how to implement this in Delphi?

• How to Inject code in c# method calls from a separate app

  - by Fusspawn

  I was curious if anyone knew of a way of monitoring a .Net application's runtime info (what method is being called and such) and injecting extra code to be run on certain methods from a separate running process. say i have two applications: app1.exe that for simplicity's sake could be class Program { static void Main(string[] args) { while(true){ Somefunc(); } } static void Somefunc() { Console.WriteLine("Hello World"); } } and I have a second application that I wish to be able to detect when Somefunc() from application 1 is running and inject its own code, class Program { static void Main(string[] args) { while(true){ if(App1.SomeFuncIsCalled) InjectCode(); } } static void InjectCode() { App1.Console.WriteLine("Hello World Injected"); } } So The result would be Application one would show Hello World Hello World Injected I understand its not going to be this simple ( By a long shot ) but I have no idea if it's even possible and if it is where to even start. Any suggestions ? I've seen similar done in java, But never in c#. EDIT: To clarify, the usage of this would be to add a plugin system to a .Net based game that I do not have access to the source code of.

• What to read as a good intro and quickstart to aspect-oriented programming and metaprogramming?

  - by Ivan

  As I've found myself repeating myself a lot, writing very similar queries and classes for different entities (despite of doing strong object and relational normalisation), etc, I've came to an Idea that I could and should automate the most of this and write an engine which will compile simple declarative models I specify into all the code limiting my job to describe the task and and finally just customise the result as needed. As far as I know this is about metaprogramming and aspect-oriented programming. How do I get acquainted with modern tools available quickly so that I don't invent one more bicycle developing my own?

• Is is possible to intercept a constructor on a class you do not own?

  - by code poet

  Referring to my possible answer to this question: http://stackoverflow.com/questions/2907535/how-would-you-audit-asp-net-membership-tables-while-recording-what-user-made-the/2911616#2911616 Is it possible to intercept a call, coming from code you do not own, to a ctor on a sealed internal class that you do not own with the intention of manipulating the object before returning? Concrete example: SqlMembershipProvider, for all of it's data access, instantiates a connection helper class, System.Web.DataAccess.SqlConnectionHolder. The desired result is to intercept this instantiation and perform an operation on the public connection that is opened in the ctor of System.Web.DataAccess.SqlConnectionHolder before letting execution continue. Is this possible. If so, an brief example would be appreciated.

• What are the different methods for injecting cross-cutting concerns?

  - by Stacy Vicknair

  What are the different methods for injecting cross-cutting concerns into a class so that I can minimize the coupling of the classes involved while keeping the code testable (TDD or otherwise)? For example, consider if I have a class that requires both logging functionality and centralized exception management. Should I use DIP and inject both required concerns via an interface into the class that requires them? Should I use a service locater that I pass to each class that will require some cross cutting functionality? Is there a different solution altogether? Am I asking the wrong question entirely?

• Define pointcut to capture an interface but not parent or sub interfaces

  - by mR_fr0g

  I was wondering how to define a pointcut in aspecJ the captures any method of an interface but not the methods of any parent or sub interface. pubic interface A { void methodA(); } pubic interface B extends A { void methodB(); } pubic interface C extends B { void methodC(); } I would like a poincut that only catches methodB() and not methodA() or methodC(). Is there any way i can do this in a general way without listing all the sub and super interfaces in the pointcut?

• Silverlight Spring Effect on TextBlock control

  - by CJCraft.com

  Hi, I'd like to create view that if the user clicks on a control, let's say a TextBlock, that the control would spring back and forth in place from where the user clicked. By spring I mean push back and forth like if there were springs behind the TextBlock in each corner. I've seen demos of this type of effect, and for the life of me, I can't come up with the name of the effect to help with searches, or find an example of this. Maybe instead of a TextBlock it would help to image a picture that could be pressed down on, and as if springs were behind it and then would bounce back into place.

• Problem in Apache CXF (Simple Frontend): 'Already connected'

  - by seanizer

  I am using apache CXF for the first time. I am trying to establish a connection based on the CXF simple front end (Configuration notes) technology. I can't really see what I've done wrong, but I am getting a weird error (see below). I have also posted this question to [email protected], but I haven't received a response yet. Perhaps someone here can help. The service bean that is wrapped here is a Spring / JPA service that does not know anything about the web, I want to use simple frontend to publish it as a web service without having to annotate it with Jax-ws etc. (This works in theory).

• What are the downsides to using dependency injection?

  - by kerry

  I recently came across an interesting question on stack overflow with some interesting reponses.  I like this post for three reasons. First, I am a big fan of dependency injection, it forces you to decouple your code, create cohesive interfaces, and should result in testable classes. Second, the author took the approach I usually do when trying to evaluate a technique or technology; suspend personal feelings and try to find some compelling arguments against it. Third, it proved that it is very difficult to come up with a compelling argument against dependency injection. What are the downsides to using dependency injection?

• Programming in academic environment vs industry environment [closed]

  - by user200340

  Possible Duplicate: Differences between programming in school vs programming in industry? This is a general discussion about programming in the industry environment. The background story is that my colleague sent me a very interesting article called "10 Things Entrepreneurs Don’t Learn in College." The first point in that post is about the author's experience of programming in the academic environment vs industry environment. After finishing a 4 year Computer Science degree course, I am currently working in the academic environment as a developer, mainly writing Java, J2EE, Javascript code. I know there are differences between academic programming and industry programming, but I was shocked after reading that post. Trying to avoid this happening on me in the future, or the others. Can anyone from industry give some general advice about how to program in industry. For example, What exactly happens when a task is received? What is the flow from the beginning to the end? What are the main differences between the programming in industry and academia? Is it more structured? Are more frameworks used? It would be great if some code examples could be given. Thanks.

• aspect parameter validation [closed]

  - by user12558

  Hi, Im doing a POC using Aspectj. class BaseInfo{..} class UserInfo extends BaseInfo{..} class UserService { public void getUser(UserInfo userInfo){..} public void deleteUser(String userId){..} } I've defined an advice, that gets invoked when I pass an UserInfo instance.But when i try to pass the BaseInfo, the advice is not getting invoked. Below block executes the afterMethod as expected for getUser. &ltaop:pointcut id="aopafterMethod" expression="execution(* UserService.*(..,UserInfo,..))" / &gtaop:after pointcut-ref="aopafterMethod" method="afterMethod" / But when i try to give BaseInfo instead of UserInfo, the aspect is not getting triggered. Am i missing something? Kindly help me on this issue.

• Ibatis startBatch() only works with SqlMapClient's own start and commit transactions, not with Sprin

  - by Brian

  Hi, I'm finding that even though I have code wrapped by Spring transactions, and it commits/rolls back when I would expect, in order to make use of JDBC batching when using Ibatis and Spring I need to use explicit SqlMapClient transaction methods. I.e. this does batching as I'd expect: dao.getSqlMapClient().startTransaction(); dao.getSqlMapClient().startBatch(); int i = 0; for (MyObject obj : allObjects) { dao.storeChange(obj); i++; if (i % DB_BATCH_SIZE == 0) { dao.getSqlMapClient().executeBatch(); dao.getSqlMapClient().startBatch(); } } dao.getSqlMapClient().executeBatch(); dao.getSqlMapClient().commitTransaction(); but if I don't have the opening and closing transaction statements, and rely on Spring to manage things (which is what I want to do!), batching just doesn't happen. Given that Spring does otherwise seem to be handling its side of the bargain regarding transaction management, can anyone advise on any known issues here? (Database is MySQL; I'm aware of the issues regarding its JDBC pseudo-batch approach with INSERT statement rewriting, that's definitely not an issue here)

• Using ControllerClassNameHandlerMapping with @Controller and extending AbstractController

  - by whiskerz

  Hey there, actually I thought I was trying something really simple. ControllerClassNameHandlerMapping sounded great to produce a small spring webapp using a very lean configuration. Just annotate the Controller with @Controller, have it extend AbstractController and the configuration shouldn't need more than this <context:component-scan base-package="test.mypackage.controller" /> <bean id="urlMapping" class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" /> to resolve my requests and map them to my controllers. I've mapped the servlet to "*.spring", and calling <approot>/hello.spring All I ever get is an error stating that no mapping was found. If however I extend the MultiActionController, and do something like <approot>/hello/hello.spring it works. Which somehow irritates me, as I would have thought that if that is working, why didn't my first try? Does anyone have any idea? The two controllers I used looked like this @Controller public class HelloController extends AbstractController { @Override protected ModelAndView handleRequestInternal(HttpServletRequest request, HttpServletResponse response) throws Exception { ModelAndView modelAndView = new ModelAndView("hello"); modelAndView.addObject("message", "Hello World!"); return modelAndView; } } and @Controller public class HelloController extends MultiActionController { public ModelAndView hello(HttpServletRequest request, HttpServletResponse response) throws Exception { ModelAndView modelAndView = new ModelAndView("hello"); modelAndView.addObject("message", "Hello World!"); return modelAndView; } }

• Dependency Injection into your Singleton

  - by Langali

  I have a singleton that has a spring injected Dao (simplified below): public class MyService<T> implements Service<T> { private final Map<String, T> objects; private static MyService instance; MyDao myDao; public void set MyDao(MyDao myDao) { this. myDao = myDao; } private MyService() { this.objects = Collections.synchronizedMap(new HashMap<String, T>()); // start a background thread that runs for ever } public static synchronized MyService getInstance() { if(instance == null) { instance = new MyService(); } return instance; } public void doSomething() { myDao.persist(objects); } } My spring config will probably look like this: <bean id="service" class="MyService" factory-method="getInstance"/> But this will instantiate the MyService during startup. Is there a programmatic way to do a dependency injection of MyDao into MyService, but not have spring manage the MyService? Basically I want to be able to do this from my code: MyService.getInstance().doSomething(); while having spring inject the MyDao for me.

• JAR files, don't they just bloat and slow Java down?

  - by Josamoto

  Okay, the question might seem dumb, but I'm asking it anyways. After struggling for hours to get a Spring + BlazeDS project up and running, I discovered that I was having problems with my project as a result of not including the right dependencies for Spring etc. There were .jars missing from my WEB-INF/lib folder, yes, silly me. After a while, I managed to get all the .jar files where they belong, and it comes at a whopping 12.5MB at that, and there's more than 30 of them! Which concerns me, but it probably and hopefully shouldn't be concerned. How does Java operate in terms of these JAR files, they do take up quite a bit of hard drive space, taking into account that it's compressed and compiled source code. So that can really quickly populate a lot of RAM and in an instant. My questions are: Does Java load an entire .jar file into memory when say for instance a class in that .jar is instantiated? What about stuff that's in the .jar that never gets used. Do .jars get cached somehow, for optimized application performance? When a single .jar is loaded, I understand that the thing sits in memory and is available across multiple HTTP requests (i.e. for the lifetime of the server instance running), unlike PHP where objects are created on the fly with each request, is this assumption correct? When using Spring, I'm thinking, I had to include all those fiddly .jars, wouldn't I just be better off just using native Java, with say at least and ORM solution like Hibernate? So far, Spring just took extra time configuring, extra hard drive space, extra memory, cpu consumption, so I'm concerned that the framework is going to cost too much application performance just to get for example, IoC implemented with my BlazeDS server. There still has to come ORM, a unit testing framework and bits and pieces here and there. It's just so easy to bloat up a project quickly and irresponsibly easily. Where do I draw the line?

• Injecting the application TransactionManager into a JPA EntityListener

  - by nodje

  I want to use the JPA EntityListener to support spring security ACLs. On @PostPersist events, I create a permission corresponding to the persisted entity. I need this operation to participate to the current Transaction. For this to happen I need to have a reference to the application TransactionManager in the EntityListener. The problem is, Spring can't manage the EntityListener as it is created automatically when EntityManagerFactory is instantiated. And in a classic Spring app, the EntityManagerFactory is itself created during the TransactioManager instantiation. <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory" /> </bean> So I have no way to inject the TransactionManager with the constructor, as it is not yet instantiated. Making the EntityManager a @Component create another instance of the EntityManager. Implementing InitiliazingBean and using afterPropertySet() doesn't work as it's not a Spring managed bean. Any idea would be helpful as I'm stuck and out of ideas.

• CSS file in a Spring WAR returns a 404

  - by Rachel G.

  I have a J2EE application that I am building with Spring and Maven. It has the usual project structure. Here is a bit of the hierarchy. MyApplication src main webapp WEB-INF layout header.jsp styles main.css I want to include that CSS file in my JSP. I have the following tag in place. <c:url var="styleSheetUrl" value="/styles/main.css" /> <link rel="stylesheet" href="${styleSheetUrl}"> When I deploy the application, the CSS page isn't being located. When I view the page source, the href is /MyApplication/styles/main.css. Looking inside the WAR, there is a /styles/main.css. However, I get a 404 when I try to access the CSS file directly in the browser. I discovered that the reason for the issue was the Dispatcher Servlet mapping. The mapping looks as follows. <servlet-mapping> <servlet-name>Spring MVC Dispatcher Servlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> I imagine the Dispatcher Servlet doesn't know how to handle the CSS request. What is the best way to handle this issue? I would rather not have to change all of my request mappings.

• How to configure LocalSessionFactoryBean to release connections after transaction end?

  - by peter

  I am testing an application (Spring 2.5, Hibernate 3.5.0 Beta, Atomikos 3.6.2, and Postgreql 8.4.2) with the configuration for the DAO listed below. The problem that I see is that the pool of 10 connections with the dataSource gets exhausted after the 10's transaction. I know 'hibernate.connection.release_mode' has no effect unless the session is obtained with openSession rather then using a contextual session. I am wandering if anyone has found a way to configure the LocalSessionFactoryBean to release connections after any transaction. Thank you Peter <bean id="dataSource" class="com.atomikos.jdbc.AtomikosDataSourceBean" init-method="init" destroy-method="close"> <property name="uniqueResourceName"><value>XADBMS</value></property> <property name="xaDataSourceClassName"> <value>org.postgresql.xa.PGXADataSource</value> </property> <property name="xaProperties"> <props> <prop key="databaseName">${jdbc.name}</prop> <prop key="serverName">${jdbc.server}</prop> <prop key="portNumber">${jdbc.port}</prop> <prop key="user">${jdbc.username}</prop> <prop key="password">${jdbc.password}</prop> </props> </property> <property name="poolSize"><value>10</value></property> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource"> <ref bean="dataSource" /> </property> <property name="mappingResources"> <list> <value>Abc.hbm.xml</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop> <prop key="hibernate.show_sql">on</prop> <prop key="hibernate.format_sql">true</prop> <prop key="hibernate.connection.isolation">3</prop> <prop key="hibernate.current_session_context_class">jta</prop> <prop key="hibernate.transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</prop> <prop key="hibernate.transaction.manager_lookup_class">com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup</prop> <prop key="hibernate.connection.release_mode">auto</prop> <prop key="hibernate.transaction.auto_close_session">true</prop> </props> </property> </bean> <!-- Transaction definition here --> <bean id="userTransactionService" class="com.atomikos.icatch.config.UserTransactionServiceImp" init-method="init" destroy-method="shutdownForce"> <constructor-arg> <props> <prop key="com.atomikos.icatch.service"> com.atomikos.icatch.standalone.UserTransactionServiceFactory </prop> </props> </constructor-arg> </bean> <!-- Construct Atomikos UserTransactionManager, needed to configure Spring --> <bean id="AtomikosTransactionManager" class="com.atomikos.icatch.jta.UserTransactionManager" init-method="init" destroy-method="close" depends-on="userTransactionService"> <property name="forceShutdown" value="false" /> </bean> <!-- Also use Atomikos UserTransactionImp, needed to configure Spring --> <bean id="AtomikosUserTransaction" class="com.atomikos.icatch.jta.UserTransactionImp" depends-on="userTransactionService"> <property name="transactionTimeout" value="300" /> </bean> <!-- Configure the Spring framework to use JTA transactions from Atomikos --> <bean id="txManager" class="org.springframework.transaction.jta.JtaTransactionManager" depends-on="userTransactionService"> <property name="transactionManager" ref="AtomikosTransactionManager" /> <property name="userTransaction" ref="AtomikosUserTransaction" /> </bean> <!-- the transactional advice (what 'happens'; see the <aop:advisor/> bean below) --> <tx:advice id="txAdvice" transaction-manager="txManager"> <tx:attributes> <!-- all methods starting with 'get' are read-only --> <tx:method name="get*" read-only="true" propagation="REQUIRED"/> <!-- other methods use the default transaction settings (see below) --> <tx:method name="*" propagation="REQUIRED"/> </tx:attributes> </tx:advice> <aop:config> <aop:advisor pointcut="execution(* *.*.AbcDao.*(..))" advice-ref="txAdvice"/> </aop:config> <!-- DAO objects --> <bean id="abcDao" class="test.dao.impl.HibernateAbcDao" scope="singleton"> <property name="sessionFactory" ref="sessionFactory"/> </bean>
