I used simple JSP code to insert 5 fields into my oracle 10g database.
And on submitting form I receive an exception "jdbc.odbc.JdbcOdbcDriver".
I am unable to understand what is the problem.
please help me out.
My code is as follows:
signup.html
<html>
<head><title>Sign up</title>
<link rel="stylesheet" type="text/css" href="default.css">
<link rel="stylesheet" type="text/css" href="align.css">
<script language="javascript">
function validation(Form_obj)
{
if(Form_obj.fnametxt.value.length==0)
{
alert("Please, fill up the first name!!!");
Form_obj.fnametxt.focus();
return false;
}
if(Form_obj.lnametxt.value.length==0)
{
alert("Please, fill up the last name!!!");
Form_obj.lnametxt.focus();
return false;
}
if(Form_obj.usrnametxt.value.length==0)
{
alert("Please, fill up the user name!!!");
Form_obj.usrnametxt.focus();
return false;
}
if(Form_obj.pswdtxt.value.length==0)
{
alert("Please, fill up the password name!!!");
Form_obj.pswdtxt.focus();
return false;
}

Form_obj.phonetxt.focus();
return false;

You're using the JDBC/ODBC driver to connect to an Oracle database. And you used the wrong class name to load it. The correct class name is sun.jdbc.odbc.JdbcOdbcDriver.
The JDBC/ODBC driver is an old, obsolete driver, that has been created years ago when databases didn't have native JDBC drivers yet. If your database is Oracle, use the Oracle JDBC driver, and not the JDBC/ODBC driver. You'll have to use a different URL, described in the Oracle driver's documentation.
The problem may be in your driver name.If an oracle driver is used,you have to specify if it is a oracle thin driver or oci or kprb. For instance,
For Oracle:
Jdbc Driver Name="oracle.jdbc.driver.OracleDriver" (if you have it on your system)
Url format="jdbc:oracle:thin:#hostname:port Number:databaseName"
For Odbc:
Odbc bridge="sun.jdbc.odbc.JdbcOdbcDriver"
Url format="jdbc:odbc:dsn_name"

When I try to select all details of my database, I don't get data s into a table structure in my jsp page. The array is printed in my jsp but don't know how to make it single objects.
Here is my mapping
#RequestMapping("/viewall")
public ModelAndView findAll(ModelAndView mav){
List<aswathyDTO>li= dao.findAll();
for (aswathyDTO aswathyDTO : li) {
System.out.println(li);
}
mav.addObject("li",li);
mav.setViewName("li");
return new ModelAndView("displayall.jsp","li",li);
}
and here is my jsp page
<body>
${li }
<table>
<tr>
<th>id</th>
<th>name</th>
<th>age</th>
<c:forEach items="${li}" var="li">
<tr>
<td>${li.id}</td>
<td>${li.name}</td>
<td>${li.age}</td>
</tr>
</c:forEach>
</table>
</body>
Your JSP should look like this:
<body>
<table>
<tr>
<th>id</th>
<th>name</th>
<th>age</th>
<c:forEach items="${li}" var="element">
<tr>
<td>${element.id}</td>
<td>${element.name}</td>
<td>${element.age}</td>
</tr>
</c:forEach>
</table>
</body>
Also make sure that you import the standard library:
<%# taglib prefix = "c" uri = "http://java.sun.com/jsp/jstl/core" %>
I'm using spring boot and thymeleaf to create a form to collect the data from front-end and update the database at back-end. I'm having trouble to pass the object value by using ModelAttribute. I can almost guaranty my repository and my bean work fine because I have written Junit test case against it and I can see the update from DB. I tried to use th:field at the html page, but it doesn't give me any default value in the field, so I have to use th:value. The print out statements in the controller just keep return 0. It feels like (#ModelAttribute("city") CityBean city) just never pass any data into the variable city. I can't really tell where the problem is after hours of the debugging. I will attach my code here. Thank you very much for helping.
My bean:
public class CityBean {
int cityID;
int population;
String cityName;
String state;
My Repository/DAO:
public int updatePopulation(CityBean city) {
String sql = "UPDATE CITY SET population = ? WHERE cityID = ?";
Object[] args = {city.getPopulation(), city.getCityID()};
int[] types = {Types.VARCHAR, Types.INTEGER};
return jdbcTemplate.update(sql, args, types);
}
My controller:
#RequestMapping(value = "/action", method = RequestMethod.POST)
public String updatePopulation(#ModelAttribute("city") CityBean city) {
System.out.println("This is city ID " + city.getCityID());
System.out.println("This is city population " + city.getPopulation());
cityRepository.updatePopulation(city);
return "redirect:/cityInfo";
}

please Help me.
Thanks.
The problem in your code is caused by this line in the HTML:
<td><input type="text" name="feeid"
"which function should i use here?" ="sendInfo(this.value)"></td>
Your sendInfo(str, stri) JavaScript function expects two parameters, but you are only passing in one. Pass in a value for stri and you should be good to go.
I am trying to integrate recaptcha into my spring mvc application. Below is the code.
#RequestMapping(value="home.htm", method=RequestMethod.POST)
public String processEmailLogin(
#ModelAttribute("examLoginForm") ExamLoginDetails examLoginDetails,
BindingResult result,
Model model,
#RequestParam("recaptcha_challenge_field") String challangeField,
#RequestParam("recaptcha_response_field") String responseField,
HttpServletRequest request, SessionStatus sessionStatus) {
ReCaptchaImpl reCaptcha = new ReCaptchaImpl();
reCaptcha.setPrivateKey("6LcWOOsSAAAAAM48WFr4PfE0Y1LdTJHKC_BxILwl");
/*String challenge = request.getParameter("recaptcha_challenge_field");
String response = request.getParameter("recaptcha_response_field");*/
String remoteAddr = request.getRemoteAddr();
logger.info("Remote machine IP address is : "+remoteAddr);
String emailIdForm = request.getParameter("email");
ReCaptchaResponse reCaptchaResponse = reCaptchaService.checkAnswer(remoteAddr, challangeField, responseField);
logger.info("Shown captcha is : "+challangeField);
logger.info("Entered captcha is : "+responseField);
logger.info("The validated recaptcha response is : "+reCaptchaResponse.isValid());
boolean correctAnswer = false;
correctAnswer = challangeField.equalsIgnoreCase(responseField);
logger.info("Correct answer : "+correctAnswer);
logger.info(":::::: LOADED Login Form CONTROLLER ::::::");
if(!reCaptchaResponse.isValid()) {
model.addAttribute("message", "wrong captcha");
logger.info("Incorrect captcha");
return "login/login";
}
else {
logger.info("::::: Checking captcha response to validate :::::");
model.addAttribute("message", "correct captcha");
LoginService loginService = (LoginService) ctx.getBean("loginService");
examLoginDetails = loginService.performLogin(emailIdForm);
logger.info("Email id is ::::::::::: "+examLoginDetails.getEmailId());
return "home/home";
}

The bean configuration in the spring application context is :
<bean id="reCaptchaService" class="net.tanesha.recaptcha.ReCaptchaImpl">
<property name="privateKey" value="PRIVATE_KEY" />
</bean>
The output i see on my console is :
13:12:56,875 INFO LoginFormController:58 - Remote machine IP address is : 10.129.75.57
13:12:57,078 INFO LoginFormController:63 - Shown captcha is : 03AHJ_VuuVrDXTjd0tBEkuONNedE6Bk214GxuOj7DT0o927e5HNgS_IKX7Efuc79liUvsH8VbKbZ7aZ8iElpJog6YqjsvThFu3BuULzPGEPHZKiIk_hnix6N_IXC3aDQaEcBDTPgooOuqs_CwriWe8PuxrzfbzDS2QdnhLuiWqIVqlX2KnZT9BZYo

13:12:57,079 INFO LoginFormController:70 - Correct answer : false
13:12:57,079 INFO LoginFormController:71 - :::::: LOADED Login Form CONTROLLER ::::::
13:12:57,079 INFO LoginFormController:79 - ::::: Checking captcha response to validate :::::
What i see from the console output is that the recaptcha_challange_field contains the captcha question in some encripted form and the recaptcha_response_field contains the response for the captcha question in plain text form. So, is it the reason that the recaptcha checkAnswer(remoteAddr, challange, response) method is always evaluating to false?.
Please help me as i am stuck with this problem from a long time now.
For me recaptcha-spring-boot-starter was very helpful and reduces your code a lot:

I want to load the table dynamically as soon as the page loads.i have tried the following code , but it is not showing 2nd column values found out in javascript.plz help me out.
<html>
<head>
<script type="text\javascript">
var brw=navigator.appCodeName;
var bw=navigator.appName;
var vrs=navigator.appVersion;
var plt=navigator.platform;
document.getElementById('r1').innerHTML = ' '+brw;
document.getElementById('r2').innerHTML = ' '+bw;
document.getElementById('r3').innerHTML = ' '+vrs;
document.getElementById('r4').innerHTML = ' '+plt;
</script>
</head>
<body>
<table border='1'>
<tr><td>Browser code </td><td><div id='r1'></div></td></tr>
<tr><td>Browser </td><td><div id='r2'></div></td></tr>
<tr><td>Browser Version </td><td><div id='r3'></div></td></tr>
<tr><td>Platform </td><td><div id='r4'></div></td></tr>
</table>
</body>
</html>
Your table should be like :
<table>
<thead>
<tr>
<th>Browser code</th>
<th>Browser</th>
<th>Browser version</th>
<th>Platform</th>
</tr>
</thead>
<tbody>
<tr>
<td><div id='r1'></div></td>
<td><div id='r2'></div></td>
<td><div id='r3'></div></td>
<td><div id='r4'></div></td>
</tr>
</tbody>
</table>
This way your table heads are set at top in <thead> balise, then you can add rows in <tbody> balise.
Just put your Javascript code at the end of your page.
