Spring - Annotations

@Repository annotation should be used to indicate those classes that compose the DAO layer.

@Service annotation can be used to designate those classes that are part of an application's service facade, which are used in the web layer to handle requests

@Controller annotation denotes the presence of a POJO that should be used for Spring MVC interactions. Defines a service facade.

Spring - Load properties

(application-context.xml)
In your application-context.xml, use the tag context:property-placeholder to define the property file where you have the values of your bean properties.


The value of location is the rath of your file:

<context:property-placeholder location="classpath*:spring/*.properties" />

In case that you have your property file outside your project:

<context:property-placeholder location=""file:///var/conf/conf.properties"/>
After define your file properties with the values:

db.name = test
db.user = user
db.password = password
db.port = 3306


Finally you can use the properties in your beans:


<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">

<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/test" />
<property name="username" value= "${db.user}" />
<property name="password" value="${db.password}" />

</bean>


(web.xml)
In the web.xml don´t forget to include the file application-context.xml


  <context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/application-context.xml
</param-value>
</context-param>

Java Project Structure

In Eclipse to add the structure folders choose New -> Soure Folder

Select the chech box "Update exclusion filters into other source folders to solve nesting"

• Within the project_name folder, we'll create the folders that are customary for a Java application:

project_name/src
project_name/src/main
project_name/src/main/java
project_name/src/main/resources

• For web applications, we need a webapp and WEB-INF folder:

project_name/src/main/webapp
project_name/src/main/webapp/WEB-INF

• We also need to create the folders that are required for unit testing our application:

project_name/src/test
project_name/src/test/java
project_name/src/test/resources

• And finally, we'll create the two folders where Spring configuration files are ordinarily placed:

project_name/src/main/webapp/WEB-INF/spring

How to read?

All the time we have new information and no time to learn everything so what I did was to learn how to read faster.

What I learned was the next points previous to the lecture:

1. About the material
• Where comes the information?
• How many time I need to spend?
• What is the relationship with me (job, hobbies)??
• Is the material appropiate?
2. What I want to read?
• Why I chose this material?
• What kind of information Am I expecting?
• Do I need to read everything?
• What the purpouse of the new information?
• The new information Would increase my knowledge?
3. Previous to read
• What I am expecting to learn?
• Would it satisfied my initials expectations ?
• Would it be easy or difficult the lecture?
4. Before read
• Your expectations were justified?
• Did you accomplish your expectations?
• Did you get a benefit, like save time or arise your knowledge?
• If you read the material for first time, would you change something?

Drools First Step

For this example use Eclipse Juno, Drools 5.4.0

1. Install in Eclipse the drools plug-in 
• Help -> Install new Software 
• Typer in "Work with" http://download.jboss.org/drools/release/5.4.0.Final/org.drools.updatesite/.  That change according with the last version
• Click Add
• Type in "type filter text", Drools
• Select the chechbox 
• Click Finish
2. Create the Drools Workspace 
• File -> Properties 
• Type "Drools" 
• In the window left side -> Configure workspace setting -> Add 
• Select from the uncompressed zip the folder \binaries, in my case "drools-distribution-5.4.0.Final\binaries"
• Click Ok to accept the changes
3. Create a Drools Project to verify
• File -> New Project -> type "Drools"
4. Create a Java class to invoke the rules
• Implement KnowledgeBuilder to parse the DRL files
• Implement KnowledgeBase to compare the object Vs rules
• 
5. Insert some object to evaluate the rules

• 
  

Project First Steps

Develop a project managment plan

I write this as result of taking one Project course and the main points are:

1. Establish the project duration
2. Calendar configuration
• Before start writing the activities configure the calendars to manage the tiem that each team member is going to be have in the project
• Configure the labors hours and hollidays
• Option: Project -> Change work time -> Create calendar
To manage globally the calendars and share between different projects
• Option: File->Information->Calendars->  
• Activity duration is different to the duration of the labor day
3. Activities
• Define the block of activities 
• Select Format -> Schema number,  to list the activities
• Relation between activities
• Finish to Start
• Finish to Finish
• Start to Start
• Start to Finish
• Define Automatic or Manual dependency between activities
• Always work with tasks of the same level
4. Milestone
• Used to define a point of control
• Define dependency between milestones
5. Constraints
• All the activities has to be programed as automatic, if not the type of constrains are unavailable.
1. Deadline.- Before type a deadline will appear a green arrow pointing the date
2. Constraints
1. As late as possible
2. As soon as possible
3. Finish no earlier than
4. Finish no later than
5. Must finish on
6. Must start on
7. Start no earlier than
8. Start no later than
3. Date constraints 
6. Resources
• Use View -> Details
• Formula   Work = Duration * Resources (Unit)

The Focus Solution

The idea of this philosophy is just be focus on the solutions as goal, following the next steps:

1. Solutions, not problems
• Detect what is working
• Take in mind what you want
• What do you want to accomplish today?
• Will you be aware if you've made progress?
• What works for you generally?
• Solution talk
2. Inbetween-the action is in the interaction
• Do small changes
3. Make use of what's there
• The solution is in front of you
• Everything is a useful thing
• Use of counters
4. Possibilities - Past, Present, Future
• Past - There is a past victory or triumph. 
• Using a scale where 10 is perfect and 1 is nothing, where are you?? Then describe how you get from the 1 to 2, then from 3 to 4, etc until achieve the perfect future.
• Present - Focus and use the things that are working fine, develop a positive trend
• Future - Create the perfect future, how the perfect future is 
5. Language
• Keep the language simple
6. Every case is different
• There isn't a general solution
7. Optimistic and pessimism
