--DelegatingActionProxy

==>Spring & Struts

What configuration files are required?

1. web.xml : Servlets entries..2. struts-config.xml : struts entries..3. spring-config.xml : Spring entries [ActionServlet-servlet.xml]..

There are 3 ways are provided by spring to integrate struts & Spring..1. DelegatingActionProxy2. DelegatingRequestProcessor3. ActionSupport

1st Approach : DelegatingActionProxy

Steps To integrate 1. Configure "ContextLoaderPlugIn" in the struts-config.xml to read the spring configuration file...

<plug-inclassName="org.springframework.web.struts.ContextLoaderPlugIn"><set-property property="contextConfigLocation"

value="/WEB-INF/ActionServlet-servlet.xml" /></plug-in>

Note : In the web.xml

<servlet-name>ActionServlet</servlet-name><servlet-class>

org.apache.struts.action.ActionServlet</servlet-class>

By default "ContextLoaderPlugIn" takes the spring configuration file name as <servlet-name>-servlet.xml,If the spring configuration file name is different then we need configure it using "contextConfigLocation" property.

2. Any request forward to D.A.P and the actual action class entry should be given in the spring configuration file, So that we can inject Service -> Action..

I) student.jsp M - I

<html:form action="StudentAction">

II struts-config.xmlM - I

<action path="/StudentAction"

type="org.springframework.web.struts.DelegatingActionProxy"/>

III) action-servlet.xmlM - I

<bean name="/StudentAction" class="edu.actions.StudentAction"/>

--DelegatingRequestProcessor2nd Approach : DelegatingRequestProcessor








2. In previous D.A.P example we are forwarding Any request to D.A.P and here don't configure any Action class name in the struts-config.xml (Don't give the type Attribute), Instead of configure it, Let's configure DelegatingRequestProcessor class in the struts-config.xml using <controller> tag..

<controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor" />

Action class entry should be given in the spring configuration file, So that we can inject Service -> Action..

M - I<action path="/StudentAction"/>

<controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor" />

III) action-servlet.xmlM - I

<bean name="/StudentAction" class="edu.actions.StudentAction"/>

--ActionSupportAnd4WithOutCLP3rd Approach : ActionSupport








2. In previous D.A.P and D.R.P example's we are giving Action class entry in the spring configuration file and here let's configure it in the struts configuration file and all the Action class should extend ActionSupport..

public class StudentAction extends ActionSupport {

public ActionForward execute(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response)throws Exception {

ApplicationContext context = getWebApplicationContext();

Service service = (Service) context.getBean("service");}

}Note : Here we can the W.A.Context object from base class (ActionSupport), So that we can get the service object from the W.A.Context..

Action class entry is there in the struts configuration file, So that we can't inject Service -> Action..



II struts-config.xmlM - I

<action path="/StudentAction"type="edu.actions.StudentAction"/>

4th Approach : WithOutCLP**Note : Here We are not using Spring Web features to integratestruts & spring, We are using Spring core to read the spring configuration filein the ServiceFactory.

ServiceFactory : To read the spring Configuration file and when ever required return service object..In the Action class take help from S.Factory and get the service objects..

*****Note : D.A.P and D.R.P examples we are able to inject Service -> Action.ActionSupport and WithOutCLP examples we are not able to inject Service -> Action.===================================================

--StrutsSpringHibernate

Final Example : StrutsSpringHibernate

Steps :

1. Create a Web Project.2. Add Struts Capabilities and using struts-config.xml design create Action, Form and JSP.3. Add Spring Capabilites. [Select Core, Web, ORM].4. Add Hibernate Capabilites..Using Reverse Engineering Create POJO and HBM..Create Dao, Service ..etc and update Spring-configuration file With T.M.

Note : StudentForm Shouldn't be passed to dao becaz S.Form is Struts Specific So we are using

BeanUtils.copyProperties to copy StudentForm data

to Student... and pass student object to Dao....----------------------Most of projects we integrate struts and Spring using

DelegatingActionProxy and we don't use Processor becaz

if we want implement custom processor then it becomes complex... and we don't use ActionSupport also becaz we are not able to inject Service -> Action..

--ContextLoaderPlugIn

package org.springframework.web.struts;

import org.apache.struts.action.PlugIn;

public class ContextLoaderPlugIn implements PlugIn {public static final String DEFAULT_NAMESPACE_SUFFIX = "-servlet";public final void init(ActionServlet actionServlet, ModuleConfig

moduleConfig) throws ServletException {try {

this.webApplicationContext = initWebApplicationContext();onInit();

}catch (RuntimeException ex) {}

}protected WebApplicationContext initWebApplicationContext() throws

BeansException, IllegalStateException {WebApplicationContext parent =

WebApplicationContextUtils.getWebApplicationContext(getServletContext());

WebApplicationContext wac = createWebApplicationContext(parent);

// Publish the context as a servlet context attribute.String attrName = getServletContextAttributeName();getServletContext().setAttribute(attrName, wac);return wac;

wac.setServletContext(getServletContext());wac.setNamespace(getNamespace());if (getContextConfigLocation() != null) {

wac.setConfigLocations( StringUtils.tokenizeToStringArray(

getContextConfigLocation(), ConfigurableWebApplicationContext.CONFIG_LOCATION_DELIMITERS));

}wac.refresh();return wac;

}public String getNamespace() {

if (this.namespace != null) {return this.namespace;

}if (this.actionServlet != null) {

return this.actionServlet.getServletName() + DEFAULT_NAMESPACE_SUFFIX;

}return null;

}}

The actual Flow :

ActionServlet.init() -> ActionServlet.initModulePlugIns() [plugIn.init()] ->ContextLoaderPlugIn.init() ->ContextLoaderPlugIn.initWebApplicationContext() -> ContextLoaderPlugIn.createWebApplicationContext() ->ContextLoaderPlugIn.getNamespace() <=|

Note : "ContextLoaderPlugIn" is used to read the spring-configuration file and create WebApplicationContext object and keep the W.A.Context object in Servlet Context Scope..



import org.apache.struts.action.Action;

return delegateAction.execute(mapping, form, request, response);

}protected Action getDelegateAction(ActionMapping mapping) throws

BeansException {WebApplicationContext wac =

getWebApplicationContext(getServlet(), mapping.getModuleConfig());String beanName = determineActionBeanName(mapping);return (Action) wac.getBean(beanName, Action.class);

}protected WebApplicationContext getWebApplicationContext(

ActionServlet actionServlet, ModuleConfig moduleConfig) throws IllegalStateException {

return DelegatingActionUtils.findRequiredWebApplicationContext(actionServlet, moduleConfig);

}protected String determineActionBeanName(ActionMapping mapping) {

return DelegatingActionUtils.determineActionBeanName(mapping);}

}

public abstract class DelegatingActionUtils {public static WebApplicationContext

findRequiredWebApplicationContext(ActionServlet actionServlet, ModuleConfig moduleConfig)

throws IllegalStateException {

WebApplicationContext wac = getWebApplicationContext(actionServlet, moduleConfig);

}public static WebApplicationContext getWebApplicationContext(

ActionServlet actionServlet, ModuleConfig moduleConfig) {return (WebApplicationContext)

actionServlet.getServletContext().getAttribute(ContextLoaderPlugIn.SERVLET_CONTEXT_PREFIX +

modulePrefix);

}public static String determineActionBeanName(ActionMapping mapping)

{return mapping.getPath();

}}

Note : D.A.Proxy is delegating the request to the actual Action class.1. Get the W.A.C from S.Context.2. Identify the beanName. (It will resolve path, Here path and beanName both are same).

}public static String determineActionBeanName(ActionMapping mapping)

{return mapping.getPath();

}}

Note : D.R.Processor is delegating the request to the actual Action class.1. Get the W.A.C from S.Context.2. Identify the beanName. (It will resolve path, Here path and beanName both are same).3. pass the beanName to W.A.Context and get and return the Action class object.** D.R.Processor is overriding processActionCreate and

it's using Spring W.A.C and resolving Action class object,If it is not able resolve from spring configuration then it willresolve from Struts configuration file becaz it's callingsuper.processActionCreate() Method..Here Action class object creation is done by spring and

the other flow is done by struts means population of the data,validation, calling Action.execute() and forwarding to the success/ failure page.

--BasicJSFSpring & JSF.......JSF Basic...

Struts JSF1. Action/ Form Java Bean2. struts-config.xml faces-config.xml3. Action Tags... managed-bean4. Forward Tags.. navigation-rule5. name attribute from-outcome6. path attribute to-view-id7. ActionServlet FacesServlet8. <html:text/> <h:inputText/>9. <html:submit/> <h:commandButton/>10. <bean:write/> <h:outputText/>----------Note : In struts directly we can call student.jsp and here Don't call the student.jsp.Forward the request to FacesServelt which will display student.jsp. The forward logic is there in the index.jsp and we are giving it in the web.xml

== index.jsp<jsp:forward page="student.faces" />

It will be forwaded to "FacesServlet" and it will display student.jsp

JSF is the specification and the implementation is doneby Icefaces/MyFaces/RichFaces....etc.

1. In JSF the same application UI we can use both Server Side and Mobile application...2. The complete UI, We can controll at server side.3. Like swing applications, We can do event handlingin the web application using JSF.

--DelegatingVariableResolver==> Spring & JSF

What configuration files are required?

1. web.xml : Servlets entries..2. faces-config.xml : JSF entries..3. spring-config.xml : Spring entries [applicationContext.xml]..

There is 1 way, provided by spring to integrate JSF & Spring..

1. DelegatingVariableResolver/SpringBeanVariableResolver

1st Approach : DelegatingVariableResolver

Steps To integrate 1. Configure "ContextLoaderListener" in the web.xml file to read the spring configuration file...

<listener><listener-

class>org.springframework.web.context.ContextLoaderListener</listener-class></listener>

By default "ContextLoaderListener" takes the spring configuration file name as "applicationContext.xml",If the spring configuration file name is different then we need configure it using "contextConfigLocation" property.

2. To inject service -> Bean (Student), Let's configure "DelegatingVariableResolver" in the "faces-config.xml".

Note : 1. Here we are giving JSF Bean entry in the "faces-config.xml" file and service class entry in the "applicationContext.xml". 2. We need to inject Service -> Bean so let's configure it in the "faces-config.xml" using <managed-property>

<property-name>service</property-name><value>#{service}</value>

</managed-property>

<managed-property/> is similar to <propery/> in Spring.

"DelegatingVariableResolver" will resolve spring configuration file entries in the JSF configuration file...

--FacesContexttAndWithOutCLL2nd Approach : FacesContext

Steps To integrate 1. Configure "ContextLoaderListener" in the web.xml file to read the spring configuration file...

<listener><listener-

class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

By default "ContextLoaderListener" takes the spring configuration file name as "applicationContext.xml",If the spring configuration file name is different then we need configure it using "contextConfigLocation" property.

2. We are not injecting service -> Bean (Student), So"DelegatingVariableResolver" is not required in the "faces-config.xml".Here we are writing ServiceFactory and it's used To get the Service object in the Bean class.In the service Factory we required 2.1 S.C to get W.A.C. 2.2 "request" to get S.C. and "request" object is not available so to S.C We are using "FacesContext"..Final points.. Get the FacesContext, Get the S.C from F.Context, Get the W.A.C from S.C and Get the service object from W.A.C.

Note : We are not injecting service -> Beans, So Let's get the service object in the bean class using ServiceFactory....===================================================3rd Approach : WithOutCLLHere We are not using "ContextLoaderListener" to read the spring configuration file and We are not using "D.V.Resolver" also so we can't inject service -> Bean

**Note : Here We are not using Spring Web features to integrate JSF & spring, We are using Spring core to read the spring configuration file in the ServiceFactory.

ServiceFactory : To read the spring Configuration file and when ever we required return service object..In the Bean class take help from S.Factory and get the service objects..

***Note : 1. DelegatingVariableResolver example we are able to inject Service -> Bean.2. FacesContext and WithOutCLL examples we are not able to inject Service -> Bean.===================================================

--SpringJSFJPA==> 4SpringJSFJPA

Steps To integrate

1. Create the Web Project.2. Add the JSF capabilities.3. Add the Spring capabilities.

4. Add the JPA capabilities.To integrate SpringJSFJPA follow "Spring & JSF" and "Spring & JPA" steps.. [DelegatingVariableResolver and 1LocalEntityManagerFactoryBean example Steps]
