Step 10 :
Now Create "view" folder under "WebContent/WEB-INF" .Again create one jsp file "articlesList.jsp" in "view" folder . The code of "articlesList.jsp" given below as :
|
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%> <html> <head> <title>All Articles</title> </head> <body> <c:if test="${!empty articles}"> <h1 align="center">List Articles</h1> <hr width=500 > <table> <tr> <th>Article ID</th> <th>Article Name</th> <th>Article Description</th> <th>Added Date</th> </tr> <c:forEach items="${articles}" var="article"> <tr> <td><c:out value="${article.articleId}"/></td> <td><c:out value="${article.articleName}"/></td> <td><c:out value="${article.articleDesc}"/></td> <td><c:out value="${article.addedDate}"/></td> </tr> </c:forEach> </table> </c:if> <c:if test="${empty articles}"> <c:out value="Not Available Article Details"></c:out> </c:if> </body> </html> |
Step 11 :
Now create "searcharticle.jsp" jsp file under "WebContent/WEB-INF/view" directory . The code of "searcharticle.jsp" given below :
|
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%> <%@
taglib
uri="http://www.springframework.org/tags/form" <html> <head><title>Add Article</title></head> <script language="JavaScript"> function Validate(){ var articleid =document.getElementById("articleid").value; if(articleid=="" || articleid.length<1){ alert( "Please enter article id." ); document.getElementById("articleid").focus(); return false; } if ( isNaN( articleid ) ){ alert( "Please enter a valid article id." ); return false; } return true; } </script> <body> <h1 align="center">Search Article</h1> <hr width=500 > <c:url var="viewArticlesUrl" value="/articles.html" /> <br /> <br /> <c:url var="saveArticleUrl" value="/articles/save.html" /> <form:form
modelAttribute="article"
method="POST"
onsubmit="return Validate();"> <table align="center"> <tr> <td><form:label path="articleId">Article Id:</form:label></td> <td><form:input path="articleId" id="articleid" /></td> <form:errors path="articleId" > </form:errors> </tr> <tr> <td></td> <td><input type="submit" value="Search" /></td> </tr> </table> <br/> </form:form> </body> </html> |
Step 12 :
Now open "web.xml" file and modify as :
|
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:web= xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http: version="2.5"> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>*.html</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.html</welcome-file> </welcome-file-list> </web-app> |
Step 13 :
Now create "dispatcher-servlet.xml" file under "WebContent/WEB-INF" directory . The code of "dispatcher-servlet.xml" given below as :
|
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" 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 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"> <context:property-placeholder location="classpath:jdbc.properties" /> <context:component-scan base-package="net.roseindia" /> <tx:annotation-driven transaction-manager="hibernateTransactionManager"/> <bean id="jspViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <property name="prefix" value="/WEB-INF/view/" /> <property name="suffix" value=".jsp" /> </bean> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="${database.driver}" /> <property name="url" value="${database.url}" /> <property name="username" value="${database.user}" /> <property name="password" value="${database.password}" /> </bean> <bean
id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation <property name="dataSource" ref="dataSource" /> <property name="annotatedClasses"> <list> <value>net.roseindia.model.Article</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">${hibernate.dialect}</prop> <prop key="hibernate.show_sql">${hibernate.show_sql}</prop> </props> </property> </bean> <bean id="hibernateTransactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> </beans> |
Step 14 :
When run "Hibernate3QueryExample" on tomcat server display output as :
