In my project, I am creating a Cancel Account facility to delete the account from user table. The user table name is newuser. The cancelaccount jsp looks like:
<%# page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

background-repeat:no-repeat;
background-position: top right;
}

font-family: serif;
font-weight: bold;
color: blue;
size: 5px;
text-align: center;
}
</style>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<form action="Cancelaccount" name="cancelaccount">
<p>Are you sure to cancel account?</p>
<p>If yes please retype the password</p>
<p><input type="password" align="middle" name="password"></input></p>
<input type="submit" value="Cancel Account"></input>
<p>Else click here</p>
</form>
</body>
</html>
In Cancelaccount servlet, I am trying to match the current input password with the password registered with the account open. If they match the account should be cancelled,otherwise not.So the servlet code is:
import getset.Getset;
import java.io.IOException;
import java.io.PrintWriter;
import java.sql.SQLException;
import accessdb.Dao;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
public class Cancelaccount extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* #see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {
// TODO Auto-generated method stub
Getset g = new Getset();
Dao dao = new Dao();
PrintWriter pw = response.getWriter();
String password = request.getParameter("password");
HttpSession session = request.getSession();
String userid = (String)session.getAttribute("userid");
if (password.equals("") || password.equals(" "))
response.sendRedirect("UserHome.jsp");
g.setuserid(userid);
g.setloginpassword(password);
try {
String password1 = dao.getregpasswordbyuserid(g);
if (password1 == password) {
dao.cancelaccount(g);
pw.println("<html>Your Account has been successfully cancelled from the system.<p>" +
"Click here to go to Start Page<html>");
session.invalidate();
} else {
response.sendRedirect("UserHome.jsp");
}
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
The DAO functions code are:
public void cancelaccount(Getset g)throws ClassNotFoundException,SQLException{
//Delete a user from NEWUSER TABLE AND MEALDB TABLE
Connection con=Dbconnection.getConnection();
String userid=g.getuserid();
PreparedStatement pstmt=con.prepareStatement("delete from mealdb where userid=?");
pstmt.setString(1, userid);
pstmt.executeUpdate();
PreparedStatement pstmt1=con.prepareStatement("delete from newuser where userid=?");
pstmt1.setString(1, userid);
pstmt1.executeUpdate();
}
public String getregpasswordbyuserid(Getset g)throws ClassNotFoundException,SQLException{
//GET PASSWORD BY USERID
Connection con=Dbconnection.getConnection();
String userid=g.getuserid();
PreparedStatement pstmt=con.prepareStatement("select regpassword from newuser where userid=?");
pstmt.setString(1, userid);
ResultSet rs=pstmt.executeQuery();
rs.next();
String p=rs.getString(1);
System.out.println(""+p);
return p;
}
And the stacktrace is:

In the DAOs' cancelaccount function I deleted from another table mealdb also, because the userid field is a primary key in newuser and foreign key in mealdb. I looked into it hard, but could not find a way. Thank you.
try changing the code in the getregpasswordbyuserid() to
ResultSet rs=pstmt.executeQuery();
String p="";
while(rs.next()){
p=rs.getString(1);
System.out.println(""+p);
}
return p;
The problem has been resolved. I just changed the servlet code and it worked. The userid value from the session was not being fetched successfully. The working code is:
import getset.Getset;
import java.io.IOException;
import java.io.PrintWriter;
import java.sql.SQLException;
import accessdb.Dao;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
public class Cancelaccount extends HttpServlet {
private static final long serialVersionUID = 1L;
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {
// TODO Auto-generated method stub
Getset g = new Getset();
Dao dao = new Dao();
PrintWriter pw = response.getWriter();
String password = request.getParameter("password");
System.out.println("" + password);
HttpSession session = request.getSession(true);
String userid = (String)session.getAttribute("USERID");
System.out.println("" + userid);
/* if(password.equals("") || password.equals(" "))
{
response.sendRedirect("UserHome.jsp");
} */
g.setuserid(userid);
try {
String password1 = dao.getpasswordbyuserid(g);
System.out.println("" + password1);
if (password1.equals(password)) {
dao.cancelaccount(g);
pw.println("<html>Your Account has been successfully cancelled from the system.<p>" +
"Click here to go to Start Page<html>");
session.invalidate();
} else {
response.sendRedirect("UserHome.jsp");
}
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}

I have tried to put a props.put("mail.smtp.ssl.enable", "true") but that too didn't seem to work. I suspect there is some error with the properties i am configuring but i am unable to find the solution yet. I have also referred to this FAQ section of Java mail.

How to convert Part to Blob, so I can store it in MySQL?

I want to upload a file and save it to mysql database. thus far, I am able to upload the file, print its detail.

First, you must register your driver at the beginning so DriverManager can user it when getting a connection. It might vary on the implementation.
DriverManager.registerDriver (new com.mysql.jdbc.Driver());
or
Class.forName("com.mysql.jdbc.Driver");
Then you can perform a getConnection() because you'll have a driver registered to be used by DriverManager.
Second: /webapps/ROOT/WEB-INF/lib is a different context and its libraries won't be available for your app unless you are setting the context path of your app as shown in this question. If you wanna add it, try placing your JDBC driver on /webapps/<yourapp>/lib first. Tomcat lib should work as well (but it's not nice when you distribute your app, might conflict with other apps deployed there, using different versions of the driver, etc.)
Third: When asking here, try to reduce your verifiable example to something readable. There's a lot of code which is not relevant to your problem. Reducing makes it easier to read your question and provide help.
I have got log in and register screen for android app and the activities associated with them when the register or log in buttons are clicked. I dont get any errors while saving it.
But when I run it, the screen loads up in emulator, allows me to enter data, but as soon as I click on Register button or Login button, I get error "Application Stopped Unexpectedly, Please try again ".
Following is the error that I get in LogCat:

It looks to me, like registerErrorMsg is null - e.g. your text view is not found in the layout. It is possible, that the id you use (R.id.register_error) is declared in another element.
I have a RESTeasy service thats running on JBOSS AS 7, that is trying to create a connection with a local database (mysql server).
The data source is properly defined in the JBOSS management and connects fine (a JSF app can connect fine with it and it can modify the database), however when I try to connect in my RESTeasy service, it gives me a nullPointerException and I can't seem to figure out why. kumonobs is the database in question. The error occurs in the persist method, which is called through a post request. Any help would be much appreciated, if any additional information is needed please ask!

Found the solution, instead of the Annotation to the datasource use:
String strDSName = "java:jboss/datasources/thenamehere";
ctx = new InitialContext();
dataSource = (javax.sql.DataSource) ctx.lookup(strDSName);
