Design Patterns in Database Applications with Java (Java EE / Java SE)

I've been reading StackOverflow for quite a while now and I'm only now building the nerve to ask a question. I'm 20 years old and currently enrolled in college in IT here in my hometown (Cluj-Napoca, Romania). Enough for introductions :D.


Basically I have my little software firm that provides Book-keeping appz. They're (horrifyingly) written in Delphi and I want to start from scratch and write them in Java. I've had little experience with Java in the past but I want to learn and I've chosen Java because of the cheap and quality tools the platform offers.


Now could you please point me to the right direction as where could I find some complete docume

Sample Java EE projects using Java EE design patterns
Java

For .Net there are lots of projects that Microsoft/others provide via which one can learn how patterns etc. are implemented in real life projects.


I am looking for ones for Java EE (apart from the samples that Sun provides on:http://java.sun.com/javaee/reference/code/). Am looking for more complex ones. May be using JSF/Spring/Struts


Design level query regarding Database access layer implementation for Java applications
10/1/2015 5:10 pm Java

Objective : I want to design a DAO layer for may application , which will be used by web-applications and core java programs also.

  1. Fist is it a good approach to have webservice for each database operation (like : http://sometomcatappurl//insertEmp,updateEmp) I am planning to configure connection pool in context.xml of tomcat Access the data-source using spring , perform operation using jdbc template I will use batch update in few places where i need to process requests in bulk.

  2. The above URL will be call from various internal applications to communicate with database.

  3. Per day requests expected 10-Million Inserts , 20-Million Updates, 20-Million selects.

Concern: Java, Tomcat , DB oracle and mysql are the technology constraints -

Which approach will be the fastest and salable way dealing with huge database operators.

Can spring handle huge requests, is it a good approach to have a web-service to perform database operations.

Note: I don't want to bloat my applications by writing database connection every where by accessing from a properties file, that is the reason going for context declaration with pool size.


Patterns for deploying layered business applications written in Java
Java

I'm working on a layered business application written in Java that should be packaged as an EAR file and deployed to a JBoss application server. There's a web-application layer, a service layer, a domain layer but no persistence layer. At least on paper.


What is the best practice for deploying the different layers? In our team we have a little religious war going on between:


Packaging each layer in its own JAR file (e.g. in its own Maven module), and adding each module to the EAR file, OR
Bundling everything together in a single JAR file, with each layer mapped to a package naming convention.

Are there other possibil
