ejb-3.1

I have an existing EJB project set up in Eclipse Helios, and would like to slowly introduce Scala into the project. The Scala IDE has been installed successfully, and I'm able to create standalone scala project. The issue however comes when trying to use my existing project with scala additions. I've went as far as manually editing the .project, .classpath, and related files under .settings of the project's home directory for eclipse. However I still have the issue where the Java compiler tries to compiles .scala classes, which results in errors and ultimately not being able to build the

If i'm working with ejb 3.1, what's the différence between <packaging>jar</packaging> and <packaging>ejb</packaging> ... <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-ejb-plugin</artifactId> <version>2.3</version> <configuration> <ejbVersion>3.1</ejbVersion> </configuration> </plugin> As mentioned at http://maven.apache.org/plugins/maven-ejb-plugin/usage.html , "The plugin doesn't do any EJB specific processing during the generation of the jar except for validating the existence of an EJB deployment descriptor if the EJB version is 2.0+ " Since you have ejb 3.1 the ejb

I am trying to understand the differences between the EJBContainer class provided by Java EE 6 for embeddable unit testing of EJB modules and Arquillian. Is there a good resource or can someone help me in understanding this? Is it worth to write Arquillian tests when I could test EJBs using an embeddable container? Full disclosure: I'm contributor of Arquillian Arquillian is a component model for integration testing . By using the EJBContainer , you bring the runtime(the container in this case) in your tests . By bringing the runtime in your tests, you add configuration complexity to them.

I created a EJB3.1 and injected CDI bean using the @inject but facing some issues while unit testing however when tested from the servlet its working fine. I have the beans.xml in the WEB-INF folder. Below is my EJB code: @Stateless public class CdiUsingEjb { @Inject private HelloServletCDIPojo helloServletCDIPojo; public String greet() { assert helloServletCDIPojo != null; return helloServletCDIPojo.from(); } } Below is my CDI bean: public class HelloServletCDIPojo { public String from() { return "from HelloServletStateless CDI"; } } I created a JUnit class: public class CdiUsingEjbTest {
