Why MinuteProject?• Why code generation?• Do not reinvent the wheel
– i.e. let the others do the framework/specs• Crystallize your knowledge• Go fast and customise• Reverse-Engineering is not a one shot process
When to use it?• Legacy model upgrades to new tech
• Work from scratch: – Development tool – Iterative methodology
• Your own model as your technology tutorial

Demo 1 – JPA2
http://minuteproject.blogspot.be/2012/05/rigajug-demo-1-jpa2.html
Demo 1 - explanations
• Start from scratch• Generate from the console & command line• Review artifacts • Write a unit test
Customisation• Art of enrichment• Art of reverse-analysis• Configure model/target
Configuration optionsIndividual (fine grain)Global (declarative conventions)

Demo 2 – JPA2
http://minuteproject.blogspot.be/2012/05/rigajug-demo-2-jpa2.html
Demo 2 - explanations
• Start from scratch• Generate from the console & command line• Review artifacts• Write a unit test• Secure modified code
Integration Technics2 standards• integration by extension• integration by overridingMP adds a new one• integration by alteration/mutation• 3 types of alteration
– artifact level (exclude for next generation)– added section– updatable section
Demo 3 - REST
Architecture blocks
http://minuteproject.blogspot.be/2012/05/rigajug-demo-rest-cxf.html
JPA2
DAO
CXF SPRING
Demo 3 - explanations• Start from scratch• Artifacts review:
– CXF track– Spring config– Backend DAO– JPA2– Maven projects
• Deploy and test on Tomcat• Test URL
SDD – Statement Driven Dev. • Sometimes statements are just enough• Model is secondary• You just need:
– Statement ex: query– I/O
SDD exampleStart from an SQL query to deduce function and output
select k.key_name, t.translation, t.date_finalization, l.code, l.description, tl.first_name, tl.last_name, tl.email from translation t, language l, user tl, translation_key kwheret.language_id = l.idlanguageand tl.idUser = t.translator_idand k.id = t.key_idorder by key_name
SDD exampleProvide some input
select k.key_name, t.translation, t.date_finalization, l.code, l.description, tl.first_name, tl.last_name, tl.email from translation t, language l, user tl, translation_key kwheret.language_id = l.idlanguageand tl.idUser = t.translator_idand k.id = t.key_idand k.key_name like ?and l.code like ?order by key_namelimit ?
SDD - exampleFeed statement into Minuteproject
<query name="get translation info"> <query-body> <value><![CDATA[select k.key_name, t.translation, t.date_finalization, l.code, l.description, tl.first_name, tl.last_name, tl.email from translation t, language l, user tl, translation_key k where t.language_id = l.idlanguage and tl.idUser = t.translator_id and k.id = t.key_id and k.key_name like ? and l.code like ? order by key_name limit ?]]> </value></query-body>
SDD - exampleFeed input into Minuteproject
<query-params>
<query-param name="key" is-mandatory="false" type="STRING" sample="'test'"/>
<query-param name="code" is-mandatory="false" type="STRING" sample="'FR'"/>
<query-param name="max" is-mandatory="false" type="INT" sample="10"/>
</query-params>

SDD is WYSIWYGwhat you STATE is what you get

GoodiesWhy not have a JEE web app instantlyOpenXava app generation• Is a RAD Open Source JEE framework based on
JPA2• Has front-end rendering annotation on entities• Is AJAX
Demo 5 – OpenXava App
MinuteProject generates:• OpenXava project artifacts• Build and deploy script
http://minuteproject.blogspot.be/2012/05/rigajug-demo-instant-openxava-app.html
Extend MinuteProjectArtifacts can be generated at multiple levels:• Field• Entities (table,view)• Package • Model• Application
Extend MinuteProject• Add a track• Add template metadata• Add template (velocity)• Add library• Add plugin• Artifact cross-reference
