Hello everyone,
I've tried to get OWB working for about several hours on Tomcat 7 and
afterall I got really confused.
I'd be very thankful if someone can clarify some points with OWB.
So, I'm developing a test project with just one servlet
====
@WebServlet(urlPatterns="/test")
public class extends HttpServlet {
private @Inject MyService s;
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
WebBeansContext currentInstance = WebBeansContext.currentInstance();
MyService s2 = currentInstance.get(MyService.class);
resp.getWriter().println(s);
resp.getWriter().println("s2: " + s2.getHash());
}
}
====
it tries get injected MyService instance which is POJO:
====
public class MyService {
public MyService() {
}
public String getHash() {
return new Random().nextInt() + "";
}
}
====
here is WEB-INF/web.xml:
====
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="
http://java.sun.com/xml/ns/javaee

<resource-env-ref-type>javax.enterprise.inject.spi.BeanManager</resource-env-ref-type>
</resource-env-ref>
</web-app>

libs in WEB-INF/libs:
openwebbeans-ee-common-1.2.0.jar
openwebbeans-el22-1.2.0.jar
openwebbeans-impl-1.2.0.jar
openwebbeans-resource-1.2.0.jar
openwebbeans-spi-1.2.0.jar
openwebbeans-tomcat7-1.2.0.jar
openwebbeans-web-1.2.0.jar
xbean-asm-shaded-3.13.jar
xbean-finder-shaded-3.13.jar
The first question is about CDI implementation library.
If I try to deploy webapp as it is, the Tomcat will fail with next
exception: java.lang.NoClassDefFoundError:
javax/enterprise/context/spi/Contextual
I couldn't find OWB library which provides such class. I only
grabbed javaee-api-6.0-5-tomcat.jar from TomEE and placed in under Tomcat 7
lib/ folder.
What is a proper way to solve this problem? Where should I get
javax.enterprise.context.* library?
The second question is about CDI itself.
After successful deploying (with javaee-api-6.0-5-tomcat.jar in lib/) I
accessed my servlet by http://localhost:8080/testproject/test and got this
responce:
====
null
s2: 1064451662
====
Why WebBeansContext.currentInstance().get(MyService.class) returns a proper
instance of MyService class and fails to inject it into private @Inject
MyService s?
