Thanks for sharing this information. Its helpful.
Thanks for sharing those. Am going ahead with my preparations. Thanks for your thoughts.
Hello Folks,

Am currently learning a bunch of front end skills and would like to build my site ( everything about me, like a CV/Resume ). I am thinking about hosting it somewhere so that I could share it with people. Is there a free hosting service where I could host such front end only application ?
Thanks Foster for sharing those. I have gone through few of them and they are 3/4 years old and am not sure if things hold true today. Looking for suggestions from anyone who took it up recently.
Hello Folks,

I am planning to do OCEJPAD certification in sometime ( Targeting couple of months from now ). Is there a study group which I could be part of to complete this. I don't use JPA on my day-to-day work and I planning to go through the Pro JPA 2 book. Would that be sufficient or could someone give me some pointers on how to go about it.

Also let me know if I need to upgrade my ocjp in order to take this up. I did my OCJP in 2010

Having interfaces & domain on the classpath of the client makes a very tight coupling. Is this not a drawback of RMI ?

Or is this the place where Webservices over powers RMI ?

If I understand you correctly, should I have the interface and domain Object in my client side as well ?

Then any change on server, requires appropriate changes in the client as well ?

Hi All,

I am working on Spring-RMI integration, following what is provided in "Spring in Action" book.

I want to know should we have to re-create the interfaces & domain Objects in client side as well. (That definitely doesn't look the way)

I get a compile time exception stating the server side interfaces & domain Objects are not found.

Any help is appreciated.

Server Side Code :

Application.java


Employee.java (Domain)



Interface


Implementation


Server side Configuration File


Client Side Code

Application.java



Client Side configuration file

Thanks Jeanne for your reply.

I feel doing SCBCD and then doing SCEA would make my fundamentals more strong.

Or will it be a over kill as SCEA expects one to have completed SCWCD itself. Any thoughts.

Hi All,

I have completed my SCWCD in early 2011. I am planning to take up another certification, as I consider doing certification is an opportunity to learn a technology in depth. I have around 3 years of experience and I haven't been very comfortable with EJB , but I have good understanding of Spring Framework. Also currently I don't use EJB at my work, neither I expect to use it in near future. So should I go and learn something in which am not comfortable and master it with SCBCD or Should I opt for next higher level of certification, i.e SCEA. Should I opt for SCBCD or SCEA ?

In case I opt for SCEA , how good an architect be without having a good hold of EJBs. It would be great if someone weighs the pros and cons.

Hi All,

The configuration element of the logback.xml file has an attribute scan which could be set to true and this file would be scanned periodically for any changes.

Hi

I am using logback for logging in my application. I am looking to change my logging levels during runtime, instead of changing it and starting the servers again. Is there way to change my log levels dynamically ?

Hi Alex,

Just when I was thinking about moving to a NoSql Database , there is a promotion for a book on one of the NoSql Databases. I couldn't ask for a better timing.

I have below questions for you

  • How do you compare a NoSql database like Hadoop with a RDBMS like Oracle ? Is migration from RDBMS to Hadoop explained in the book ?
  • There are a number NoSql Databases in the tray. How could someone very new to NoSql Database pick one from the lot out there ? How does Hadoop makes its money worth when compared with Cassandra, MongoDB , Big Table etc ?
  • What are the areas which seems to be not addressed yet in Hadoop when compared with RDBMS
  • Could you comment on the stability of the database and extent to which this has been handled in your book?

    Hi Chris,

    I found that NoSql databases are used at many places including google, Amazon. So I think Transaction or consistency would have been handled. ( Just a guess though ).

    What I am keenly watching out is, among various NoSql databases in the fray , which one would be more stable or more efficient in handling huge volume of data.

    My question might be ambiguous or might show lack of effort from my side, but right now am researching on various stuffs before deciding to dig deep on a NoSql database.
