JVM startup
Loading – finding binary representation of class/interface then constructing the Class object
Linking – combining class/interface into the run-time state of the JVM so that it can be executed

Verification - semantic/structure validation
Preparation - storage allocation, all static fields are created and initialized with default values
Resolution – optionally resolve symbolic reference to other classes/interfaces

Initialization – static initialization

superclass/superinterface static initialization

superclasses are initialized before subclasses
interface initialization does not initialize superinterfaces
only the class that declares static field is initialized, even though it might be referred to through the name of a subclass, a subinterface, or a class that implements an interface

all static explicit field initializers and static initialization blocks are executed in textual order

Instantiation - creation of object/class instance
All the instance variables, including those declared in superclasses, are initialized to their default values first.

start the constructor
call explicit constructor this() if available

call explicit/implicit super() unless class is Object – process recursively using same steps a. to e.
all non-static field initializers and non-static initialization blocks are executed in textual order
execute the rest of the body of constructor

Finalization – finalize() method is called before storage for object is reclaimed by GC
Unloading – happens if its classloader is reclaimed by GC. Bootstrap loader may not be unloaded.
Program Exit

DWR error handling

Exception/error handling of DWR calls can be centralized by setting the handlers. More here: http://directwebremoting.org/dwr/documentation/browser/errors.html

dwr.engine.setErrorHandler(UI.errorHandler);
dwr.engine.setTextHtmlHandler(UI.textHtmlHandler);

 // Handler for errors and exceptions
 errorHandler : function(msg, param2) {
  UI.hideLoading();
  Utils.resetClick();
  View.error(msg, 700)
 },

 // Handler when Ajax returns a text such as session timeout, page not found etc...
 textHtmlHandler : function() {
  UI.hideLoading();
  //View.error("Your session has expired, please login again." );
   document.location = '/adapt/web/jsp/timeout.jsp';
 },

Spring Inversion of Control

Bean Creation
- code POJO, add bean configuration element to the Spring XML configuration file or annotate the POJO

<bean id="message" class="org.springbyexample.di.xml.BelleMessage"/>

Inversion of Control
1. Constructor Injection

public ConstructorMessage(String message) {
    this.message = message;
}

<bean id="message" class="org.springbyexample.di.xml.ConstructorMessage">
    <constructor-arg value="Spring is fun." />
</bean>

2. Setter Injection

public void setMessage(String message) {
    this.message = message;
}

<bean id="message" class="org.springbyexample.di.xml.SetterMessage">
    <property name="message" value="Spring is fun." />
</bean>

3. Reference Injection

<bean id="message" class="org.springbyexample.di.xml.SetterMessage">
    <property name="message" ref="springMessage"" />
</bean>

Drools Core

create a knowledge builder to load processes from various resources (for example from the classpath or from file system)
create a knowledge base from the builder
instantiate a session based on the knowledge base
start executing processes

KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource("ruleflow.rf"), ResourceType.DRF);
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
ProcessInstance processInstance = ksession.startProcess("com.sample.MyProcess");
ksession.fireAllRules();
