问题 As you many know when you proxy an object, like when you create a bean with transactional attributes for Spring/EJB or even when you create a partial mock with some frameworks, the proxies object doesn't know that, and internal calls are not redirected, and then not intercepted either... That's why if you do something like that in Spring: @Transactionnal public void doSomething() { doSomethingInNewTransaction(); doSomethingInNewTransaction(); doSomethingInNewTransaction(); } @Transactional

问题 I am planning to run a java web application and solr in the same java container. I want the web application to be publicly accessible but solr to be accessible only to the other web applications in the same container.

问题 In order to consume a RPC web service, first I have to call a web method 'Authentication' and then I am supposed to be able to call other web methods. I have tried to implement a spring web client to consume this service but something is going terribly wrong.

问题 I'm quite new to Java EE 6 and OSGI concept, and i'm quite excited about it... The most exciting feature is the dynamic dependancy injection at execution time. I've seen some really great presentation where the application is ajaxly updated when a bundle is activated or unactivated, i like that way of decoupling the application in modules and updated it at run time ... Second though, i'm quite boring about XML configuration files, i think Java EE 6 with javax.inject and others annotations is

问题 Is there a way to import oracle defined object type in Java(JPA). I have a complex object defined in database : create or replace TYPE "myType"{ someString varchar2(100), someString2 varchar2(100), constructor....} this object type is than used in a database table. 回答1: There is no standard support for object-types in JPA. If you are using EclipseLink, you can use the @Struct annotation to map object-types, http://www.eclipse.org/eclipselink/documentation/2.5/jpa/extensions/a_struct.htm
