Modular Applications Development with Maven

Notes:

Different ways to run Maven:
http://www.vineetmanohar.com/2009/11/3-ways-to-run-java-main-from-maven/

/home/jboss1./m2/repository

<version>1.0</version> is for application, and SNAPSHOT for development

These three tags are mandatory:

<groupId>com.hollandamerica</groupId>
<artifactId>ModularApplicationTutorial</artifactId>
<version>1.0</version>

1) Create a pom.xml to compile the application into a jar called cruiser.jar. Run the test suite.

2) You want to move the development of the booking service to a separate project. Create a separate pom.xml to compile Booking.java, BookingService.java and BookingServiceImpl.java into a separate jar called booking.jar. Have cruiser.jar use booking.jar. Execute cruiser.jar to verify it works correctly.

3) You want cruiser.jar and booking.jar to always have the same version number. Create a parent pom.xml for your 2 projects called booking-parent, and define a property called VERSION. Have booking.jar and cruiser.jar make use of this VERSION property as their version number.

4) You want to compile both cruiser.jar and booking.jar in one single command. Have cruiser.jar and booking.jar be two submodules of booking-parent.

5) Split booking.jar into booking-api.jar (containing the interface) and booking-impl.jar (containing the implementation of the service). Execute cruiser.jar to verify it still works correctly.

6) We want to prevent developers of cruiser.jar to make direct calls to a specific booking-api implementation. Propose a way to remove the direct dependency between cruiser.jar and booking-impl.jar. Implement it.

CHIP Notes from Eric

Subject: Chip

Eric,

I'm digging into the com.hollandamerica.chip package, and looking at the JiBX mappings. This is part of the modularization work, trying to move the chip related code into a separate module.
Could you confirm that the following statements are correct? Unfortunately, it looks like a lot of this code was written by Jay, but I'm hoping you can help me make sure I understand it correctly:

1) Chip is an XML api for Polar only
In theory, yes.  But the word "chip" has incorrectly been translated to be any XML type service processed through WebMethods.  But Chip should only be messages to POLAR.

2) All XML messages sent to Polar through chip are buit from the CruiseLineXmlRequest Java object.
They're supposed to be.

3) The following Java classes wrap XML messages to/from Barclays, not Polar, and do not use Chip:
-CCPRequestDTO (Credit Card Process)
-ICRequestDTO   (Instant Credit Request)
-PSOfferCaptureRequestDTO  (Pre Screen Credit Card Offer)
-PSRequestDTO (Pre Screen a guest for credit card application)
I believe that's correct.  When you say "Do not use Chip", I assume you mean they don't go to POLAR through the ChipAPI.  But like I said, some people here misinterpret "chip" to be any XML going through WebMethods (like the CCPRequest and the Barclay's messages)

My initial goal was to extract the polar/chip DTOs into a separate chip-connector maven module. I might end up creating several modules at once (one per Third party system we are connecting to):
-chip-connector.jar
-barclays-connector.jar
-steiner-connector.jar
-RTD-connector.jar
OK.  Just so you know, when I was doing RTD and knew I'd have to go through WebMethods, I created a WebMethods service (com.hal.sf.service.WebMethodsService) to make the call, rather than using ChipDAO - mainly because I knew it wasn't really Chip.  However, the code that WebMethodsService uses is a lot of "chip" code (if you look at it you'll see what I mean).  I don't think it's actually uses chip, it's just that the word "chip" is in a lot of the classes and methods used in the WebMethodsService.  Unfortunately, I didn't have time to re-factor everything to be non-chip.  But if you're going to create separate modules, you might look at using that WebMethodsService and refactoring it to be non-chip.

Thanks!

There are a lot of things that can be seen through the jmx-console. Globally, it can be used to review the internal of a JBoss server while it's running. The downside is that it's hard to find what you're looking for. I usually just google what I'm looking for with "jmx-console"

RTD Performance

Subject: Not sure if you'll need this or not...

But in case Therron wants to see if RTD is doing anything, you can run this query and get the total shore excursion and revenue by day.

select DATE_BOOKED, TOTAL_BOOKED, TOTAL_AMOUNT from
(
SELECT to_char(date_booked, 'MM/DD/YYYY, DAY') as DATE_BOOKED,
to_char( COUNT(to_char(date_booked, 'MM/DD/YYYY, DAY')), '999,999' ) as TOTAL_BOOKED,
to_char( sum( amt_price), '$9,999,999.00' ) as TOTAL_AMOUNT
FROM guest_shx
WHERE date_booked > '01-JUN-12'
GROUP BY to_char(date_booked, 'MM/DD/YYYY, DAY')
)
order by DATE_BOOKED

You can change the "where date_booked" as needed to get more days, fewer days, etc.

Thanks.
