What is it?

This is your project! It is a sample, deployable Maven 3 project to help you get your foot in the door developing with Spring and Java Financial Library on Java Enterprise Edition using JSR 354

This project is setup to allow you to create a compliant Spring 3.1 application using Spring MVC.

System requirements

All you need to build this project is Java 6.0 (Java SDK 1.6) or higher, Maven 3.0 or higher.

The application this project produces is designed to be run on a Java EE 6 container server like Tomcat, Jetty or JBoss AS 7.1.

  1. Checkout and Build JSR 354

Checkout JavaMoney in the javamoney project home run

      mvn clean install

  1. Maven 3rd party JARs

    There are two 3rd Party JARs currently not available in MavenCentral or a similar Nexus. Therefore you should install them into your local repository following the Guide to installing 3rd party JARs

2.1 SDJ-ID

    mvn install:install-file -Dfile=<path-to-project>/src/etc/lib/sdj2-id.jar \
    -DgroupId=com.surveycom.sdj  -DartifactId=sdj2-id -Dversion=0.9.30 -Dpackaging=jar

2.2. JFL see

    mvn install:install-file -Dfile=<path-to-project>/src/etc/lib/jfl-1.6.1.jar \
    -DgroupId=jfl  -DartifactId=jfl -Dversion=1.6.1 -Dpackaging=jar

Starting the Application

  1. Start with Jetty

1.1 The easiest way to start the application is via the Maven Jetty Plugin. Run

      mvn jetty:run -P jetty

1.2 Access the application

The application on Jetty will be running at the following URL: http://localhost:8080/.

Start JBoss Enterprise Application Platform 6 or JBoss AS 7.1

  1. Open a command line and navigate to the root of the JBoss server directory.

  2. The following shows the command line to start the server with the web profile:

     For Linux:   JBOSS_HOME/bin/standalone.sh
 For Windows: JBOSS_HOME\bin\standalone.bat

Build and Deploy the Application

  1. Make sure you have started the JBoss Server as described above.

  2. Open a command line and navigate to the root directory of this quickstart.

  3. Type this command to build and deploy the archive:

     mvn clean package jboss-as:deploy

  4. This will deploy target/javamoney-tradingapp.war to the running instance of the server.

Access the application

The application will be running at the following URL: http://localhost:8080/javamoney-tradingapp/.

Undeploy the Archive

  1. Make sure you have started the JBoss Server as described above.

  2. Open a command line and navigate to the root directory of this quickstart.

  3. When you are finished testing, type this command to undeploy the archive:

     mvn jboss-as:undeploy

Debug the Application

If you want to debug the source code or look at the Javadocs of any library in the project, run either of the following commands to pull them into your local repository. The IDE should then detect them.

    mvn dependency:sources
    mvn dependency:resolve -Dclassifier=javadoc

Java Financial Library - API Usage

Currency Functions - import net.neurotech.currency.*

The API to use the JFL functions is very simple. To convert currencies, instantiate a Currency object and use the convert function like so:

Currency myCur = new Currency();
float result = Currency.convert(10, "CAD", "USD");

To get the mappings between names and symbols, get the hashtable of entries using:

Lister myList = new Lister();
Hashtable maps = Lister.getTable();

And then enumerate through the hash table.

Stock Quote Functions - import net.neurotech.quotes.*

There are two main functions of the Quotes package inside the JFL. To retrieve stock quotes, use the QuoteFactory. The first step is to instantiate a QuoteFactory object:

QuoteFactory qf = new QuoteFactory();

This creates a QuoteFactory that will pull it's quote information from the default data source - Yahoo Finance. Now to grab an actual Quote object, use the factory like so:

Quote microsoft = qf.getQuote("MSFT");

This method can throw a QuoteException when there's an error in the retrieval process.

Now you can access information from the new Quote object:

float price = microsoft.getPrice();
long volume = microsoft.getVolume();

The other main function of the Quotes package is to search for symbols given a company name. First, instantiate the Searcher object:

Searcher searcher = new Searcher();

Then use the Search method, which returns a LinkedList:

LinkedList hits = searcher.Search("VA Research");

Note that this method will throw a SearchException if there is a problem making the query.

Now the linked list will now contain a bunch of SearchHit objects, which have two methods:

searchhit.getSymbol();
searchhit.getResult();

You can go through this list and allow the user to choose the closest match for their search.
