Single page application with Java EE/Wildfly: server-side configuration

由 半世苍凉 提交于 2019-12-22 09:55:02
问题 I want to write an SPA with AngularJS on client side and Java EE on server side. If I understand it correctly, the idea for the frontend is to create a default page (let's call it index.html ) and implement routing to exchange parts of this default page. So with every request the default page is loaded and the routing logic replaces its parts depending on context path: <!-- index.html --> <html> <body> <!-- this block is replaced depending on context --> <div ng-view></div> </body> </html> <!

@Singleton bean failed to initialize because of not expected transaction status 4 when it's marked TransactionAttribute=NOT_SUPPORTED

由 和自甴很熟 提交于 2019-12-22 09:40:10
问题 I'm having difficulty with my EJB3.1 bean initialisation and more specifically to do with it failing due to perceived transaction rollback, even though I've marked the bean with @TransactionAttribute(NOT_SUPPORTED) . This should mean that any client transaction is paused on bean method entry until exit (when it will be resumed. It's definitely the transactional apprach I want. The "gist" of the code and error are as follows (note some of it is hand-cranked to hide details but is all relevant

Message Driven Bean Selectors (JMS)

由 你说的曾经没有我的故事 提交于 2019-12-22 08:39:32
问题 I have recently discovered message selectors @ActivationConfigProperty( propertyName="messageSelector", propertyValue="Fragile IS TRUE") My Question is: How can I make the selector dynamic at runtime? Lets say a consumer decided they wanted only messages with the property "Fragile IS FALSE" Could the consumer change the selector somehow without redeploying the MDB? Note: I am using Glassfish v2.1 回答1: To my knowledge, this is not possible. There may be implementations that will allow it via
