Hi, Can Python be a good alternative to a web app that would otherwise be developed with JEE / J2EE? If so, which Python web app framework(s) may be a good choice? Please see details about the app below. I've asked a few people individually about this, who have worked for a good amount of time on either or both of JEE and Python web app...
I have a EAR with a number of EJB dependencies. 2 of these have a provided scope dependency to the glassfish-embedded-all jar. However when I do a mvn install on my local machine or when the application is build through maven on hudson the ear always contains the glassfish-embedded-all jar. e.g. DataAccess-ejb with provided dependency ...

I know that we should not start threads in a servlet is that threads should be managed by the container.

I am new to Java EE and am working on an existing project. When I try to build the project, the build fails because the unit tests are failing. But when I run the unit tests alone, they all run fine. Is it some problem with the build settings ? It will be great if someone could help me with where to look at. Thanks a lot. ...

Hi, all. I want to enable the users of my website to upload their Java programs as a set of jar files. Of course I want to restrict the classes they can see or use, along with the underlying machine resources such as the heap, the threads, the disk, the consumed processor, etc, etc. I want a server to manage, store and run those user ...
I'm developing an application on Glassfish 3. I have an EJB that looks like this: @LocalBean @Stateless public class MyBean { public void doSomething() {} } My client code (running inside the same application) looks like this: MyBean mb = (MyBean) InitialContext.doLookup(MyBean.class.getName()); According to a few sources, this s...
My need is to hide some specific code to the client. The fact is that I have a SessionBean using RemoteInputStream. To use this SessionBean, the client needs to use the rmiio API to generate a compliant RemoteInputStream. What I want to do it something like replacing the SessionBean interface with an abstract class to include in this ...
I have a small yet complete JEE 6 application at hand. The traditional annotations are being used: @Resource, @EJB, @Singleton, @PostConstruct, @PreDestroy, @PersistenceContext, @ManagedBean, @ManagedProperty, @RequestScope, @ApplicationScope,... I would like to evaluate whether it makes sense to introduce CDI, and to standardize ...
I'm writing test code to test a client-server application. The application under test consists of an application that runs on Tomcat or another Java EE application server, and client jars that expose an API. I'm basically writing test code that uses this client API to connect to the server. In addition to extensively testing the ...

What's the exact difference between @JoinColumn and @PrimaryKeyJoinColumn? You use @JoinColumn for columns that are FKs. A typical column could look like (e.g. in a join table with additional attributes): @ManyToOne @JoinColumn(name = "...") private OtherClass oc; What happens if I promote the column to be a/the PK, too (a.k.a. ident...

I've just looked into the code of javax.ws.rs.core.MediaType and wondered about throw new RuntimeException("Compiled Code"), since I've never seen that before. I think is a form of "not implemented", but don't know. package javax.ws.rs.core; import java.util.Map; import javax.ws.rs.ext.RuntimeDelegate.HeaderDelegate; public class Med...
