Hello Cameron,

Does your book cover hibernate performance tuning? I hear things like don't put join tables (associative tables) in their own mapping files. I have been tasked with figuring out how to improve the mapping design on a project because one transaction is generating like 3 constant selects then 1 additional select for each child row in this particular relationship.

I see heavy use of bag elements with inverse="true" and every table is in it's own mapping file.

Thanks!!!

Typing is optional in groovy correct? So does it attempt to derive type when compiling to byte code or is everything just Object?

Hi Chet and Guy,

I looked at your book on Amazon, and I have no doubt it will be a great read, however I didn't see anything specific to JavaFX. Does your book go into that technology?

Thanks!

Is JQuery covered in the book?

Thanks!
Hello,


Google has done a fantastic job with abstracting the need to know the browser specific code when using GWT for the browsers it supports. What if you are using the GWT and you come across a browser that isn't supported? Are you able to modify the code generated by the toolkit?

Thanks!

GWT
Hello,

If you have some Ruby code that has hooks into a native library, is there a way to validate that native library exists on the target platform that the gem is being installed to?

Thanks!

Hello authors,

Does your book cover the limitations of the GWT, and ways to work around them while still using the GWT? Specifically, I am looking at features like drag and drop, which I last read that GWT didn't support it.

Thanks!

Hello,

Are there any topics for a developer that has been using Hibernate and Spring and wants to jump in to EJB3?

Thanks!
Hi all,

I cleared the exam this morning with an 82%. A little lower than I would have liked, however it is an improvement over the HFSJ final mock score of 50% just two weeks ago.

Many thanks to the authors of the HFSJ book! That book style is simply the best! If you want to learn about exam topics then this book is a must!

My preparation:

  • Read the HFSJ book twice.
  • Schedule the exam 2 months out (Setting a date was important).
  • Read the HFSJ book two more times.
  • Took the final mock exam with two weeks to go.
  • Actually implemented the code samples on my localhost (VERY IMPORTANT).


  • If I had a chance to do this over, I would move step 5 to the top.
    I am going to be taking the test this Friday. I took the final mock this morning (while have not looked at the book since last week), and got 35 of the questions right.

    Should I be worried that I am not ready to pass?
    Hi guys,

    Yes, I know; a simple question that I could easily get by reading Amazon ( I have), however it would be cool to hear direct from you.

    I work server side Java (and some client too) by day. I have learned Ruby via your Pickaxe book, and Rails through the first edition, and work on the Ruby quiz to keep the skill going at night.

    So what would someone with my background like about the second edition?

    Thank you!

    Any plans in the project to create a port of iText to Ruby so that we don't need something like JRuby?
    How does EJB 3 compare to "lighter weight" frameworks like Spring with Hibernate?
    I have used MyEclipse for Struts, Spring, and Hibernate features. I do see it has JSF features too. It has a base price of $30, but it is worth it.

    I have been using JDBC in serveral applications for awhile now. I have wrote dynamic SQL against Sybase, SQL Server, DB2, and Access (using the ODBC bridge). I have also written PreparedStatements against DB2 and SQL Server. I have not yet had the opportunity to use Oracle as the database, until now. My new job uses Oracle as the database, and I was wonder what things about JDBC are Oracle specific?
