EJB Injection in JSP with Java EE 7

User suexec asked ##java about accessing an EJB from a JSP template. User dreamreal (i.e., your author) put together a simple application (rather imaginatively called “suexec-war” ) to explore the possibilities. The application was built from Adam Bien‘s minimalistic Java EE 7 Maven archetype, deployed into Wildfly 10.0. It turns out that to the best of my understanding, injection of an EJB into a JSP is simply unsupported. The JSP can use...

Big news: JRebel 7 has been released, with a new agent enabling you to change class hierarchy and interface implementations on the fly. For Spring it now also supports reconfiguring dependency injection in non-singleton scoped beans. From Light Java, “JEE is dead.” Misses a lot of history – blames Java EE for WebLogic’s speed and deployment model (what about containers like Orion, which could deploy the same apps in a few seconds, and didn...

kumuluzEE is “A lightweight framework for developing microservices using standard Java EE technologies and migrating existing Java EE applications to microservices.” It’s not immediately clear from the web page what makes it ideal for migrating to microservices, but there it is. “Don’t Even use COUNT(*) For Primary Key Existence Checks” has some valuable performance advice, and considers multiple DB implementations while offering it. Now for some Scala stuff: “Quo Vadis, Scala?” has some...

“O Java EE 7 Application Servers, Where Art Thou?” is a humorously-titled summary of the state of Java EE 7 deployment options, covering the full and web profiles for Java EE 7. It’s the sort of thing one wants to know, honestly: great job, Antonio. From Stack Overflow, “How to get started with Akka streams?” is a Scala question, not a Java one, but Akka has a Java implementation as well. The first...

Tomcat and JNDI

Let’s consider the standard baseline Java EE application: it’s a web application, with some kind of framework, using JDBC or something that wraps it. In canonical Java EE form, it would be a JSF front end and request routing mechanism, with JPA as the data framework, with resources acquired via JNDI. (Note: “canonical Java EE form” doesn’t imply in any way that this is what people actually do, because normally people avoid...
