Move your HTML file into the jsp and then populate your text fields as the following
<td><b>Employee Id:</b></td>
<td><input type="text" name="employeeid" value=<%=request.getParameter("employeeid")%>></td> //etc
Note, however, that java expressions inside a jsp file (<%= %>) are considered bad practice but they are fine if it's just a simple page.
You really should create a servlet and move your business logic there (database access etc).

Im trying to generate a search options and in myweb page the user choose the value that is looking for this is my html code:
<table>
<tr>
<td><h2 align="left">Red Social: </h2></td>
<td>
<select th:field="*{redes}" name="redSoc">
<option th:each="r : ${redes}" th:value="${r.nombreRedSocial}"
th:text="${r.nombreRedSocial}"></option>
</select>
</td>
</tr>
<tr>
<td><input type="submit" value="Buscar"/></td>
</tr>
</table>
And this is my controller code:
#GetMapping("/RedesSociales")
public String infoPorRedSocial(Model model, #RequestParam(name = "redSoc", required = false) String redSoc) {
RedesSociales[] redes = redesService.obtenerTodasRedes();
model.addAttribute("redes", redes);
//model.addAttribute("grupo", null);
System.out.println(redSoc);
if (redSoc != null) {
System.out.println(redSoc);
model.addAttribute("info", infoService.obtenerTodosPorRedSocial(redSoc));
}
return "visual/reportes/ListarPorRedSocial";
}
Now as you can see im trying to get the value redSoc but im not sure how to the get this value from the selected option i tried several methods but didnt work.
EDIT:
I was using this code:
<form action="/RedesSociales" method="GET">
<h2 align="left">Red Social: </h2>
<input type="text" name="redSoc"/> <br>
<input type="submit" value="Buscar"/>
</form>
But this was not usefull because the option would be insert by the user and i wanted to made it more dynamic thats why now im using the current values stored in the database
already solve the problem Change my code to this :
<table> <tr> <td><h2 align="left">Red Social: </h2></td>
<td> <select name="redSoc"> <option th:each="r : ${redes}" th:value="${r.nombreRedSocial}" th:text="${r.nombreRedSocial}">
</option>
</select> </td> </tr>
<tr> <td><input type="submit" value="Buscar"/></td> </tr> </table>
this is part of my code :
<script>
function setCard() {
var carta = document.getElementById('idlistaCarte').value;
document.getElementById('idcodice_carta').innerHTML = carta;
}
</script>
<table>
<tr>
<td><p>Conferma Pagamento</p></td>
</tr>
<tr>
<td><select name="listaCarte" id="idlistaCarte">
<%
int i = 0;
for (String titolareCarta : listatitolare_carta) {
%>
<option value="<%=listacodice_carta.get(i)%>"
id="idcodice_carta_select">
<%=titolareCarta%>,<%=listacodice_carta.get(i)%>,<%=listatipologia_carta.get(i)%>
</option>
<%
i++;
}
%>
</select></td>
</tr>
<tr>
<td><input type="button" onclick="setCard()" value="Set Card"></td>
<td><p id="idcodice_carta"></p></td>
</tr>
<tr>
<td><input type="text" placeholder="codice_carta"
name="codice_carta" id="idcodice_carta" required></td>
</tr>
</table>
I'm trying to pass the value in the input type text with id = "idcodice_carta" taking the value from the select via button.
I can not make it.
trying to populate a p tag this works, but I need to have the value in the input field.
How can I solve the problem?
Thank you in advance.
you need to change id either
<td><p id="idcodice_carta"></p></td>
or
<input type="text" placeholder="codice_carta"
name="codice_carta" id="idcodice_carta" required>
you can't use same id in one page ex "idcodice_carta"
This is my controller
#RequestMapping(value = "/deleteMultiple", method = RequestMethod.POST)
public ModelAndView deleteEmp(#ModelAttribute("employee") Employee emp,#RequestParam(value="Id",required=false) String Id,Model model) {
List<Employee> empList = empService.getEmpList();
List<Employee> empListById = empService.getemp_IdDetails(Id);
empList=empService.searchEmpDetails(emp);
empList.addAll(empListById);
Employee emp1=new Employee();
if(empList!=null){
model.addAttribute("delete", empList);
if(empList.isEmpty()){
model.addAttribute("message","This Employee Details are not present");
}
}
model.addAttribute("employee", emp1);
return new ModelAndView("delete","empList",empList);
}
This is my sql
#Override
public List<Employee> getemp_IdDetails(String emp_Ids){
List<Employee> empList = new ArrayList<Employee>();
String sql="select * from EmpDetails where emp_Id IN" + " ("+emp_Ids+") ";
sql.replace("emp_Id", emp_Ids);
JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);
empList = jdbcTemplate.query(sql, new EmployeeRowMapper());
System.out.println("empList:"+empList.size());
return empList;
}
This is my jsp

Assuming this as string , since your Table details are unclear . Pass the arguments as String
ps=con.prepareStatement("update employees set EmployeeName=?,Nationality=? where employee_id=? ");
ps.setString(1,'EmployeeName');
ps.setString(2,'Nationality');
ps.setString(3,1);
Also avoid using scriptlets , read through the link Aniket suggested.
Hope it helps !!
I am trying to retrieve the value of an HTML textarea in jsp page from mysql database.The problem I am having is that I only can get he first line in the textarea(When I'm saving address in databse, It's retrieving first line only). This is happening for text box also, where data has space in the database, it's only getting first line of the data.
Thanks in advance.
