Well, it did not succed it. So, you don't give Javafx too much future?

Thanks for the answers. What I meant by client thecnologies was Java technologies that are used to build form views, in other words, technologies to build the end user interfaces.

So, the way a I see it, you can build a Javafx app and run it in a browser and in a desktop, so you are able to build a client that can be run in different enviroments. It is like code once, run anywhere.

It is like building a Swing app that can be run in a browser without any changes. That is the beauty of Javafx.

Hello, I'm starting to learn Javafx, and I have noticed that a javafx app can be run in a browser, also as desktop app, so I was wondering if JSP and other Java client technologies will disappear because of Javafx.

Thanks in advance.

Hello, I been working with Java mainly in the desktop environment, but now I'm required to develop an app for the Web, so my question is: Do I need to learn Servlets and JSP before learning a framework such as JSF?

Thanks in advance.

Hello fellows of Java Ranch. I would like to share that I just got an email from Oracle stating this:

Congratulations! You have passed the Oracle Certified Master, Java SE6 Developer certification. You are among the elite 1% of certified Java professionals who have gone on to achieve the Oracle Certified Master, Java SE6 Developer certification.



And I feel very thankful to this site because I couldn't have successfully developed my project without the help I found in this website.

I mainly want to thank to Roel De Nijs and Roberto Perillo, they both make an important and admirable work in helping others to improve their knowledge. And they do that efficiently, because every time I posted a question, I received a proper answer very quickly, making me advance in my project.

I think this is the first time I feel very thankful to people that I have not even seen. But I know that this part of the Internet era.

Thanks again.

Roel Thanks again. You have been very helpful during the development of my project.

As you said it will be one the easiest exams I will take in my life, I can assure you it will not be one the cheapest.
Hello, tomorrow I'm taking the essay part. I would like to ask you if you have any advices on taking this part of the certification.

Thanks in advance.
Roel: Thanks a lot again.

So with java -jar runme.jar will the examiners start both, client and server?
I'm writing my server code, but now I'm wondering if I need to start the RMI Registry through code. Because if I do, perhaps you can help me to do it.
Or the examiners start the RMI Registry.

I've been testing the server, writing the rmiregistry command in a command window.

Thanks in advance.
My assignment states:

- I must allow the user search data for all records, or for records where the name and/or location fields exactly match values specified by the user.
-It must present search result in a Jtable
-It must allow the user to book a selected record, updating the database accordingly.

I have already implemented the Database Interface, but now I want to create an Adapter whose methods will be exposed in the service interface .
So I wonder, if I need to declare the delete and create methods from the Database Interface in my Adapter Interface, because the clients won't need them, as you can read above.

Any advice?

Thanks in advance again.
Hello, I would like to konw about local variables declarations.

I read the coding standard chapter of Sierra and Bates' book, and they say that "Declare and initialize local variables before other statements (whenever possible)".

So, what about variables that I'm goin to use down the code of a method? What is the point of having to declare all this variables near the method's declaration, just like we do with instance variables near the class declaration.

Like this:


I think if someone starts reading this methods he/she would not know what those variables are for, because they are going to be used deep down the method. Would be easier just to declare the variables just before we use them?
Roel, now that I am writing the lock related methods, another question arose. I was using the Facade approach(for the Data class) with two working classes. One class for the data access related methods, and the second one for the lock related ones. But the lockRecord method throws a RecordNotFoundException. So I figure that I need to check the database file in order to find out if the record number exists, if it doesn't, the exception will be thrown.

I already have a method that performes this search, but in the data access working class. If a create an instance of this class(data access working class) in the record locking working class, both classes would be tightly coupled, therefore what would be the point of having a Facade, but with two tightly coupled classes?

Could be a good approach just to implement the DBAccess interface in the Data class?
