Netbeans and Corba

Is Corba still around or is Java EE the new standard in distributed apps?
I'm wanting to implement Corba in a solution where a web application communicates via Corba with a server application. The server application performs caching and data retrieval. I'm having trouble finding where to download the neccessary tools to develop a Corba app and if there's a Netbeans plugin.
In older versions of Netbeans, one can enable RMI and Corba distributed application but I can't find the option in versions 6.8 and 6.9.
Thanks.

Yeah it was a multi-question post. I forgot Java EE runs over Corba. I thought about web services in my app but since the front end is a web app already, I didn't see the reason to go that route. What I wanted to do was run a standard Java application in the background on the server that processes csv, processes new database entries, etc. The web application would call upon this Java app for data. The Java app would retrieve it from a cache and spit it back to the web app. If data wasn't in the cache, it would continue in the background processing data for the cache after the data has been passed back to the web app.
Maybe there's a way to have such an app run within the web container that I'm not aware of? I'm using Tomcat.
Oh wait! What if I created the standard app as a web services app and have the web application just call it? but then can the web services app monitor for csv file updates?

Rmi and iiop

hi,
may i know that what is the difference b/w rmi and iiop "some one told me that it is the marrige form b/w RMI and CORBA"
please explain me or give me a link to explanation.
thanks in advance!

Java rmi vs Corba

Hello guys, I'm currently doing research trying to conduct a performance evaluation on java rmi and corba. To do this I have built a chat application and a file transfer application using both technologies (java rmi and corba) I will be using sockets for the client/server communication, I am currently testing for, memory usage of the client application, average data throughput, total packets sent and lost and cpu times for both client and server, I'm still researching on the best possible way to conduct the test and would appreciate it if anyone could help me on what tools to use and ways to conduct this test, thanks...

I will be using sockets for the client/server communicationYou will be using RMI or Corba for the client/server communication actually.
I am currently testing for, memory usage of the client application, average data throughput, total packets sent and lost and cpu times for both client and serverYou should also test latency
I'm still researching on the best possible way to conduct the test and would appreciate it if anyone could help me on what tools to use and ways to conduct this test, thanks...You could probably automate it using JMeter. Very handy thing. You can write both the client and the server in Java, using either RMI/IIOP or IDLJ for the Corba part. No particular reason not to use RMI/IIOP that I can see, it's just a thin layer over the other, more or less, and it's much easier to program.

Corba,RMI and RMI-IIOP

Can someone help me understand and analyze the marshaling techniques of CORBA, RMI and RMI-IIOP??

RMI/JRMP is easy, just read the RMI Specification:
http://java.sun.com/j2se/1.5.0/docs/guide/rmi/spec/rmi-protocol.html
CORBA is not so easy. Find the GIOP and IIOP specifications at http://www.omg.org

Must redeploy app or get java.rmi.AccessException: CORBA NO_PERMISSION 9998

Hello. I'm hoping someone can give me a clue to the source of this problem.
I have a very simple test application which consists of one EJB which is just a stateless session bean that has a method which return the String "Hello". This method can only be run by a user in the "test" role.
I have a simple commandline client packaged in the application. I use deploytool to extract the Client.jar and I can run it with appclient - client myClient.jar. This little class connects to the bean in the server (via jndi lookup as per all tutorial example) and calls the sayHello() method. A login dialog appears in order to authenticate the user as it should and everything works perfectly ... BUT ...
If I stop the server and start it again and try to run the client exactly the same way (appclient - client myClient.jar), I get the error message below. The application is running and I confirm that its there using deploytool and asadmin to list components, etc. The only way I can get it work again is by redeploying the application.
I've looked around and found nothing about this regarding Sun Java System Application Server Platform Edition 8 2004Q4 Beta (which is what I'm using). I found some vague references to a similar sounding problem from people using Application Server 7, but the work around in those posts references switches and settings in deploytool that dont seem to be there in my version.
Can anyone suggest a fix? I'd like the application to work upon starting up the server each morning for example without having to redeploy it. I'm glad to provide my test application archives and sources to anyone who would find them useful for solving this problem.
Thanks!

Hi Raja.
So Sorry for the delay. Anyway, I've come back to try to do this now and just cant make the problem happen! I'm tearing my hair out to figure out what has changed. In the meantime, I'm going to just move past this. If it shows up again, I'll be sure to post all related files back in this forum.
Thanks!

Do anybody have any idea on how to resolve this?

There is no firewall settings between the client and server sides. I checked the JDK ORB on the server, it run well at the moment of MarshaoException. Normally, we will have the MarshalException when the stub class in the client side is not up to date...any other possible reasons?
May I have some suggestions? Or my statement is not clear enough?
Thanks

Any idea how to get rid of this problem. Thank you.

Hi,
I am not very sure whether it will work but I have read somewhere that this exception occurs if the Remote Object size is more than the Java stack size at the client side which is by default 256 Kb. So. it might be possible that if the Stub size exceeds, then Client is not able to load the Stubs and hence the Marshal Exception is coming.
I think increasing the Java stack size of the Web\ EJB containers might resolve the issue.

Java.rmi.MarshalException: CORBA MARSHAL 0[Error unmarshaling value [Error

I'm here to ask this question.
Let me describe the problem.
I have a EJB call that can be excute use Struts Action class(just a general Java class).
When I call this EJB in other Java class method then have below errors.
Any body has any idea what's this error means? Thanks in advance!!

You must be more precise about the problem. Explain how your CORBA ORB is related to your EJBs or your RMI code, and WHO calls WHOM. We simply dont know what you're talking about.

Java.rmi.MarshalException : CORBA MARSHAL 1398079699

I deployed an application with a stateless SessionBean
in J2EE 1.3.
When accessed from a non-java client using JNI, I got InvocationTargetException
"java.rmi.MarshalException : CORBA MARSHAL 398079699 Maybe;
nested exception is: org.omg.CORBA.MARSHAL: minor code: 1398079699 completed: Maybe"
Anybody encountered a similar problem ?

Hi,
I think i have exactly the same problem as you. I have a client app accessing a stateless session bean .
The error I get seems to be related to the argument passed to the method i'm calling. In my application I am passing in a "complicated" value object to the session bean. My guess is that the value object is not compliant with the CORBA rules.
I'm trying to find out what is and isn't legal for Value Objects. the least i know is that the value object must implement Serializable.
I'll keep you posted If i can sort it out.

Relation between EJB and CORBA

Hi,
I'm confused as to the relation between EJB and CORBA. Some books I've read say that CORBA is used to implement the underlying RMI protocol in EJB while others say it is an alternative to EJB.
Could someone please clarify.
Thanks

Could you pleae restate your question.
I'm assuming you want to bind a Corba object to a
CosNaming service from within a j2ee component. JNDI
supports this case fully via their CosNaming service provider
(see http://java.sun.com/products/jndi/serviceproviders.html) JNDI is part of J2SE, so it's fully available to any J2EE component.

Rmi and EJB

Hi guys,
i feel ejb is internally using rmi.Am i right?what are the differences between rmi and ejb and also what r the similarities?
Thanks
Regards
Vivek.S

RMI is just an API that allows Java classes to be invoked remotely. It uses Java Remote Method Protocol. But it also can use IIOP in which case this whole thing is called RMI-IIOP.
RMI doesnt provide any component model like EJB, that has several types of components with well defined behavior and purpose.
Since EJB's can be called remotely they may use JRMP but it's not mandatory.
EJB's have to use IIOP as a connection protocol to ensure interoperability among EJB servers and CORBA ORB's. So EJB' s use RMI as an API, but they have to support IIOP and optionally some other protocols like JRMP. For example, WebLogic supports some interesting protocol called T3.

RMI and SOAP

hai everybody,
I wanna know the differences in using RMI and SOAP concepts.
can we use SOAP in place of RMI?
Im new to SOAP.
I want use SOAP concept in my project to work with the database by sending data through SOAP messages using xml to remote server.
there i want call some remote methods to insert data in to database from the SOAP messages.
Is it necessary to use RMI here or we can manage vth SOAP concepts?
can any one suggest in such situation?
Thanks in advance for ur reply

They are essentially the same. RMI is a little bit more abstract - SOAP defines one way you can do RMI. Others are things like CORBA and DCOM.RMI and SOAP are not the same at all. RMI is java's remote procedure call (RPC) mechanism and is java to java only. SOAP is used for exchanging XML-based messages and is cross-platform.
