So as the title says, I'm inserting information in mysql database but only the file that I'm uploading is inserted into database. Everything else is NULL. I suspect it has something to do with the creation of temporary directory on the server to save the file but then again I can't find the solution.
Here is the table I'm inserting into
CREATE TABLE DOC(IDD INT NOT NULL AUTO_INCREMENT, DOCN VARCHAR(50), AUTHOR VARCHAR(50), CAT VARCHAR(50),CONTENT MEDIUMBLOB NOT NULL, CRITN INT DEFAULT 0, PRIMARY KEY(IDD));
Here is the html form I'm fiiling
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<title>TODO supply a title</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width">
</head>
<body>
<form enctype="multipart/form-data" action="uploadfile.jsp" method="post" onsubmit="return verify()">
<table border='1'>
<tr>
<span style="color:black">Τίτλος</span> <input type="text" name="title"><p></p>
<span style="color:black">Συγγραφέας</span> <input type="text" name="author"><p></p>
<span style="color:black">Κατηγορία</span> <input type="text" name="cat"><p></p>
<td>

</td>
</tr>
<tr>
<td>
<input type="file" name="filename" id="filename"accept="application/pdf"/>
</td>
</tr>
<tr>
<td>
<input type="submit" value="Upload" />
</td>
</tr>
</table>
</form>
</body>
</html>
And here's the code for the jsp

When using enctype multipart/form-data you have to use request.getPart for the regular parameters too, as request.getParameter always returns null with multipart/form-data. The other option for processing file uploads is the Apache Commons File Upload library, but in that case as well, you have to get the regular parameters wit the same method as you get the file.

i have partial jsp file with jstl code :

'erreur'}">${form.resultat}</p>
<br />
<p id="adcli"><a href='#ADCLI'>Valider</a></p>

</form>
and principal jsp :
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<%#taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<!DOCTYPE html>
<html>

<script type="text/javascript">
constructform("<c:out value="${param['par']}"/>");

...
the partial file is loaded using jquery :
...

var principal = $("#Gc_FenettrePrincipale");
principal.empty();
principal.append("<div class=\"Gc_FenettreSec\" id=\"_ADD\"><p>Ajout

servlet call
...
request.setAttribute(ATT_FORM,form);
request.setAttribute(ATT_PARTICULIER,particulier);
response.setContentType("text/html");
this.getServletContext().getRequestDispatcher(VUE).forward(request,
response);
in the partial jsp does not work but it work in the principal jsp if used,i can't figure why
in the java channel in the irc thy suggeced to go to jsf,i can't to that now,am off of deley
Idea 1: If your JavaScript function constructform is in /ressources/_javasctipt.js, then the load request might look for /ressources/ressources/partial.jsp due to the relative URL.
Idea 2: Have you tried omitting the <!DOCTYPE html> in your partial JSP?
i figured out that load() function is http resquet,GET or POST ,and am using servlet to load jsp,so the soution is to create the hol jsp.
i don't see better solution
"an other servlet or an other jsp"
I am defining a variable in scriptlet to get value from request headers, then we are using that variable c:set to set to variable to use in c:out .But i am not getting any value c:set variable, as a result c:out is giving result as ''.
please find the code snippet below and guide me if i am missing anything.
Code in jsp:
<%# page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>DM</title>
<SCRIPT Language="JavaScript">
function submitform()
{
this.LoginForm.submit();
}
</SCRIPT>
</head>
<body onload="submitform()">
<%
String userName= request.getHeader("IV-USER");
System.out.println("name "+userName);
if (userName == null || userName.length()==0){
response.setHeader("IV-USER",userName);
response.sendRedirect("ULM.jsp");
}
%>
<c:set var="uName" value="<%=userName%>"/>
<p>Welcome1 ${uName}</p>
<form name="LoginForm" action="/ICDDMContent/STGDM.html" method="post">
<input type="hidden" name="UserId" value='<c:out value="${uName}"/>'/>
<!--
<input type="hidden" name="UserId" value="<%=userName%>" >
-->
<input type="hidden" name="Token" value="dummy">
<p>Welcome1 <c:out value="${uName}"/></p>
</form>
</body>
</html>
String userName= request.getHeader("IV-USER");
System.out.println("name "+userName);
if (userName == null || userName.length()==0){
response.setHeader("IV-USER",userName);
response.sendRedirect("ULM.jsp");
}
Is redundant piece of code, if userName is empty, you will just assign empty value to IV-USER header, if "ULM.jsp" is the same page as you've attached, and that redirect is just to set variable - here is your problem

I found solution to refresh and remember value after select option from select form. But now, i want to show all "termins" in below select form. For example: When i select first option in select form (obiekt.idObiekt = 1) then i want to show all termins for obiekt with id 1 in . Can you help me ?
First of all, put your select inside a form. So that when you submit it during refresh you can get the value it was holding with String selectedObiekt=request.getParameter("obiekt"). Then modify your option to read
<option value="<%=obiekt.idObiekt%>" <%= ((Integer.toString(obiekt.idObiekt)).equals(selectedObiekt))?"selected":""%>><%=obiekt.nazwa%>
<%=obiekt.adres%></option>
