EJB3 or Spring+Hibennate? JBOSS, Weblogic or Websphere? Oracle or MySQL?

Dear all,
I know this is a question without real answer. However, today, January 2009, if I would build a idea JEE application from scratch, should I choose
EJB3 or Spring+Hibennate?
By the way, I would also ask two other questions. Should I choose Oracle or MySQL? Should I choose Tomcat, JBOSS, Weblogic or Websphere?
I assume that I don't have budget constraint but I really want to have the "best" updated one.
Thanks for any argument.

EJB communication between weblogic and websphere

Hello:
I have weblogic 7.1 instance running in machine A and websphere running in machine B. I want to make a call to the ejb deployed from weblogic to websphere. Any experience in this would be very helpful. Or pl. post the procedure.
Thx in advance.

I don't think that there is any magic here, although I've never tried it.
All you need is the compiled EJBHome and EJBObject interfaces in the
classpath of the calling EJB, get an InitialContext in the JNDI namespace of
the target EJB container using the name of the JNDI InitialContext Factory,
do a lookup on the bean making sure to do a PortableRemoteObject.narrow when
you are casting the Home stub with the vendor specific version of
PortableRemoteObject(and that may be the real trick), call the appropriate
create method, and you are rolling.
I guess the question becomes how to make sure that when you are calling
PortableRemoteObject.narrow on the Home stub, that you get the vendor
specific version for the EJB container and JNDI namespace from which you are
doing the lookup.
I guess the answer is, I'm guessing. Have you tried it?

Override Spring jar in Weblogic 12c

Hi Folks,
We have been facing an issue while overriding the Spring jar in Weblogic 12c. Basically we need to write a bean based on some 3rd party API calling their interfaces. Now they use Spring 2.5 jar for their own implementation. Since Weblogic inherently supports Spring 3.0 jar. As a result when we write our bean wrapping their interfaces and deploy it, it doesn't work. We replicated the issue by replacing Spring 2.5 jar with Spring 3 in local environment.
If we modify the server classpath to load the Spring 2.5 jar (preceding Spring 3.0), entire soa-infra application goes down, so what We wanted to know if it is possible to override the Spring jar only for our application itself? While loading the application it will override the Spring 3.0 jar with Spring 2.5 in the application context but server will keep using Spring 3.0?
Any ideas/suggestions highly appreciated!
Thanks,
Bhaskar

Hi Bhaskar,
have you tried packing the Spring libraries in your application and using the Filterring Classloader? Maybe this links can help you :

Spring-WS with Weblogic 9.2 - HTTP 404 Error

Have deployed our Spring-WS on Weblogic 9.2 on Windows environment. The spring-ws jars have been copied to server lib directory. The the app. is deployed at the webcontext caobshared. There were no issues while deploying. Am testing the service from a soapUI tool. The url I am using is http://localhost:7002/caobshared/services. I do not see any errors or any debug statements I have in the webservice methods in the server log. Believe I am missing something or specifying incorrectly.
We need to make a decision on using Spring-WS soon, based on the POC I working on. Any help or suggestions highly appreciated.

How to build and deploy EJB3.0 jar on JBoss Server

Hi:
I want to create web service using EJB3.0.
For that first i have created EJB project,in that i add following code:
package com.ejb;
import javax.ejb.Stateless;
import javax.jws.WebService;
@Stateless
@WebService
public class TemperatureConverter {
     public double celsiusToFarenheit(double temp){
          return ((temp*1.8) + 32);
     public double farenheitToCelsius(double temp){
          return ((temp-32)/1.8);
}Now i want to build and deploy the jar on server.
How can i do this?
Thank You.

Hi AnupDesai,
I suggest you to have a read of the [*JBoss EJB3 Documentation*|http://www.jboss.org/ejb3/docs].

Runtime Datasource from Jboss/Weblogic

I have a application running JBoss, which we uses the datasource in the deploy folder.
I have the report viewer working it is using the datasource from within the report file itself. At runtime, i would like to change the datasource in the report to use the datasource from Jboss, or pass a open connection. My only want to have one connection pool managed by the applicaiton server(Jboss/Weblogic).
Thanks. Please let me know if it is unclear.

I understand that I don't have the ability to pass in a connection. However, it is possible to use the Jboss/Weblogic datasource in the deploy folder. If so, could you point in the right direction. So I could share the database connection pool.
I have tried to use the setting JNDI string in the propertyBag for the connectionInfo. However, I am unable to get it to work.
Thanks in advance for your time.

Weblogic vs Websphere

I know that this has been asked a few times but I couldn't find any recent comparisons.
So - my company is going to adopt a J2EE platform and wants to buy an appserver. We've narrowed it down to Weblogic 8.1 or Websphere 5.2
I know that early versions of Websphere got slated - but can anyone advise on how improved 5.1 is
Also we are mixed ability team with some newbies to Java. We want to adopt a uniform IDE.
Any comments on WSAD versus Weblogic Workshop. Are people using othe IDEs alongside either Websphere Server or Weblogic Server
I like the look of Workshop - but it clearly isn't as big as WSAD - and also Weblogic have introduced the concept of Java Controls which definitely isn't standards based. However our team leader thinks that this could be an easy entry point for less experienced Developers. Any comments on any of these products much appreciated

Hi,
I was looking for a comparison against the latest versions of Weblogic and websphere. I was looking at the string of posts and came to a conclusion that you were in the same situation months before and you have nailed your choice as weblogic. Could you please give me some information regarding that?
Basically am preparing a presentation with performance, scalability, features, ease of development, IDE effeciency, Integration abilities, Webservices capabilities, licensing cost and so on.

Weblogic and websphere colocated?

Has anyone ever had any experience running weblogic and websphere on the same machine? If so, what were your issues?
Thanks in advance.

Web sphere has a wide robust features which weblogic lacks some. Like the load balancing and admin console, clustering .
In Weblogic In many cases, code for applications deployed on WebLogic Server is arbitrarily structured and depends on the build process to make sense of it all. The implication of this is that existing code organization will very likely have to be changed as part of the migration effort. This may be very difficult (or even impossible) to accomplish while maintaining links to your code's history. Some organizations choose simply to archive their history and start fresh.
In WebSphere, Packaged with each module is an XML deployment descriptor that describes the organization of the components in the module and how they are configured at run time. hence applications can be migrated easily.

Basic Spring Interaction with WebLogic Portal

Can you please post the article "Basic Spring Interaction with WebLogic Portal" by Article by Mark Meyer and Don Davis. Actually it was posted in http://dev2dev.bea.com/pub/a/2006/09/weblogic-portal-spring.html but after the BEA's acquisition by ORACLE, this link was not active. Can some one please assist regarding the same ?

The archived dev2dev articles are suppose to be available at:
http://www.oracle.com/technology/pub/articles/dev2arch/index.html
But in a brief review of this site, I did not see this exact title. Maybe someone else knows where that one is.
There are many other spring related articles there you may find helpful as well.

Weblogic and Websphere communication!!

Hi Friends,
I have an EJB HelloWorld deployed on both servers(Weblogic and Websphere) and these beens are accessible easily from their respective client servlets, which is the easy part.
Now what I want to try is access the bean's methods on Weblogic server from a bean on Websphere server and vice versa. This is where I want some ideas from the gurus please.
e.g. hello() method of the EJB (HelloWeblogic) in Weblogic server prints the message "Hello from Weblogic" and the hello() method of the EJB (HelloWebsphere) in Websphere server prints the message "Hello from Websphere". Now I want to know what do I need to do so that I am able to execute hello() of the HelloWeblogic EJB, from HelloWebsphere EJB and vice versa.
I am also new to EJB, but I think I am making my way slowly.
Any help/ideas/code samples would be really appreciated.
Please feel free to ask any questions.
Regards
Rajeev

As far as I can see the standard way would be to lookup
the ejbs-home in the others JNDI context. After that proceed
as you are used to.
Troubles (or some unlikely behaviours) could occur if your beans are
served by the same interfaces.
But Dynamic Stub loading via RMI should prevent you from any problems with non existing stub/skels, etc.
You could only run into problems when stub/skel-implementation-classes where named equally (by full qualifier) in both app-servers. This should never happen. (weblogic.SomeWLStubClass != ...websphere...SomeStubClass)
Read RMI-Specification for further details on dynamic class-loading in
the RMI process:
http://java.sun.com/products/jdk/1.1/docs/guide/rmi/spec/rmi-arch.doc.html
or j2ee-tutorial on how to resolve JNDI-Contexts.
Hope it helps!

J2EE replaces BEA Weblogic, IBM WebSphere, Orion or JRun

BEA Weblogic, IBM WebSphere absolutely provide stronger ability to support enterprise applications.
I want to know whether J2EE can be used in deploying a commercial web site with multi-tier architecture. For example, to handle hundreds concurrent requests, to balance work load to some extent.
Thanks.

J2EE is a platform specification. And WebLogic, WebSphere, JRun etc. are vendor specific products that implement APIs from that platform standard.
It seems you are talking about the refrence implementation of J2EE that comes with J2EE SDK.
See http://java.sun.com/j2ee/faq.html Especially the answers therein to the two questions...
1. What is the purpose of the Reference Implementation?
2. Why don't you allow the binary Reference Implementation to be deployed or redistributed?

Install GWT, Spring, Hibernate, JBOSS

I am new to Java.
I am going to create a web application using Java, I was told I have to install GWT, Spring, Hibernate, JBOSS, JDK 6 and mySQL.
I already install mySQL and JDK 6. Do I need to install Eclipse also?
what's the pupose to install GWT, Spring, Hibernate, JBOSS? what's the relationship of them? is there any order to install them?
Thanks very much.

Then they should be prepared to provide some help with your start.
Don't say no to me, I want to give it a try.Ok, I won't say no. I will still say you'll have a hard time. Be ready to learn a lot.

Connection Weblogic and Websphere MQ

Can anybody help me how to connect Weblogic and Websphere MQ?

If you are using the foreign JMS server then create the binding file for MQ. The binding file would contain host and port and other required details.
Weblogic could understand the configuration details in that.

EJB3 or Spring+Hibennate? JBOSS, Weblogic or Websphere? Oracle or MySQL?
