C Language, Java, Advance java with all framework,Android, iPhone: how to create a simple Gujarati or any language web application in struts2 and hibernate with mysql

whenever we create a simple jsp page or html file the default char set is 'ISO' like <%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>

Because it treats English is the standard language for developing a web application.

So in order to make language specific application first we need to change the charset from ex: charset=ISO-8859-1 to charset="UTF-8".

Now I am going to create a simple application having text box is an input field to enter text in any language store it in the database and displays on the same web page.

CREATE TABLE `student_master` (

`student_id` int(20) NOT NULL auto_increment,

`student_fname` varchar(20) character set utf8 default NULL,

`student_mname` varchar(30) character set utf8 default NULL,

`student_lname` varchar(30) character set utf8 default NULL,

`student_p_add` varchar(70) character set utf8 default NULL,

`status` tinyint(1) default NULL,

`temp6` varchar(40) character set utf8 default NULL,

PRIMARY KEY (`student_id`)

) ENGINE=MEMORY DEFAULT CHARSET=latin1 AUTO_INCREMENT=11 ;

Studentform.jsp

<%@ page pageEncoding="UTF-8"%>

<%@taglib uri="/struts-tags" prefix="s"%>

<%@ taglib prefix="sj" uri="/struts-jquery-tags"%>

<!doctype html>

<head>

</head>

<body>

<s:form action="addStudent!addStudentdata.action"name="student" enctype="multipart/form-data" >

<table>

<tr>

<s:textfield name="FirstName" label="નામ" size="25" id="my"/>

</td>

<s:textfield name="MiddleName" label="પિતા / પતિ નામ" id="target" id="my"></s:textfield>

</td>

</tr>

<tr>

<td>

<s:textfield name="LastName" label="અટક" id="my"></s:textfield>

</td>

</tr>

<tr>

<td>

<s:textfield name="permanentAddress"label="કાયમી સરનામું" id="my"/>

</td>

</tr>

<s:textfield name="Phonenumber" label="ફોન નંબર" id="my"></s:textfield>

</td>

</tr>

<s:submit value="સાચવો" name="userSave" theme="simple" id="colorsubmit"></s:submit>

<s:submit id="colorsubmit" value="રદ કરો" theme="simple"/>

</td>

</tr>

</table>

</s:form>

</center>

</div>

</body>

</html>

Now I have defined the charset is "UTF-8" which is essential for any language.Now the form tag contains one text box to enter text.We need to define a accept-charset attribute of form tag to "UTF-8" to send the request to server in hindi language.

Now if the method attribute of form tag is "Get" then we need to specify request.setCharacterEncoding("UTF-8") in our Action class. and If we are using "POST" method means request is in the body then we need to add the attribute URIEncoding="UTF-8" in the server.xml file of tomcat which is in the conf directory.

for Ex:

<Connector port="8080" maxHttpHeaderSize="8192"

maxThreads="150" minSpareThreads="25" maxSpareThreads="75"

enableLookups="false" redirectPort="8443" acceptCount="100"

connectionTimeout="20000" disableUploadTimeout="true" URIEncoding="UTF-8" />

<body>

<h3>વિદ્યાર્થી માહિતી</h3>

</header>

<table>

<s:form action="addStudent!getStudentList.action" id="studentview" name="studentview">

<display:table id="liststud" list="${liststudent}" width="80%" border="1" pagesize="8" class="">

<s:hidden name="liststud.studentId" key="studentId" value="%{liststud.studentId}"/>

<display:column title="નંબર"><%=liststud_rowNum%></display:column>

<display:column title="Action">

</display:table>

</s:form>

</table>

</body>

</html>

Next step is store the value taken from the form onto the hibernate.

Now in the hibernate.cfg.xml if we are using JNDI as a datasource then we have to do some changes in the context.xml of tomcat which is in the conf directory.

<Resource name="jndi_ialds" auth="Container" type="javax.sql.DataSource" removeAbandoned="true"

removeAbandonedTimeout="60" logAbandoned="true"

maxActive="100" maxIdle="30" maxWait="10000"

username="root" password="" driverClassName="com.mysql.jdbc.Driver"

url="jdbc:mysql://localhost/dbname?autoReconnect=true&useUnicode=true&characterEncoding=utf8"/>

and if we are using a driver class in the hibernate.cfg.xml file the we add to property in our hibernate.cfg.xml file like:

Now after following these simple steps we can inset or display the Gujarati text.
