Hi Sujay,

Please find attached sample springMVC portlet . and follow steps to create SpringPortlet in Liferay 6.x

Liferay 6 HelloWorld Spring Portlet


Step 1.web.xml

Configure ViewRendererServlet in web.xml file
<servlet>
<servlet-name>view-servlet</servlet-name>
<servlet-class>org.springframework.web.servlet.ViewRendererServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>view-servlet</servlet-name>
<url-pattern>/WEB-INF/servlet/view</url-pattern>
</servlet-mapping>


Step 2.Create configurationf xml under WEB-INF folder

WEB-INF/config/springhelloworld.xml and update spring configuration details . here example for springMVC using annotation

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">

<context:component-scan base-package="com.cignex.sample.portlet" />

<bean id="messageSource"
class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basenames">
<list>
<value>content.Language</value>
</list>
</property>
</bean>

<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="cache" value="true" />
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/jsps/springsample/" />
<property name="suffix" value=".jsp" />
</bean>

</beans>

Step 3.portlet.xml

update portlet-class and configure springhelloworld.xml file in your custom portlet

<portlet-class>org.springframework.web.portlet.DispatcherPortlet</portlet-class>
<init-param>
<name>contextConfigLocation</name>
<value>/WEB-INF/config/springhelloworld.xml</value>
</init-param>



Step 4.Create SpringHelloWorld.java file under com.cignex.sample.portlet.controller .

continue with step2 . sprinhelloworld.xml file <context:component-scan/> base-path it mention com.cignex.sample.portlet . The component-scan will take care all the Controller classes.

SpringHelloWorld.java
@Controller("springHelloWorldController")
@RequestMapping(value = "VIEW")
public class SpringHelloWorldAction {

private static Log logger = LogFactoryUtil.getLog(SpringHelloWorldAction.class);

@RenderMapping
public String showViewPage(RenderRequest renderRequest,RenderResponse renderResponse) {

logger.info(" SpringHelloWorld Under Render method ");

return "viewResult";
}


}

Step 5 : .create viewResult.jsp file under /WEB-INF/jsps/springsample
continue with step2 . sprinhelloworld.xml file viewResolver configuration in springhelloworld.xml see step 2.

update viewResult.jsp file :
<div>
Welcome to Liferay Spring HelloWorld Portlet
</div
