[code]...
I have put error.jsp and badpage.jsp file in public access folder that is web content in eclipsewhen I am running the code I am status code of 500 and not the errorpage.jsp message .
I'm trying to learn java by making a login page using java, servlet, javascript, html and mysql. I can login with username and password, I can get all the information from database in the edit page. However, when I edit and click on "Submit" in EditPage.jsp, it gives HTTP Status 404. Same screen appears when I click on "Sign Up" from first page (NewFile.jsp) and click on "Submit" button after filling up user information.
I am posting all my code here but probably important ones are:
EditPage.jsp, Edit.java, EditDetails.java, UpdateUser.java and for Sign Up SignUpPage.jsp and Registration.java.
Firstly here are my error message and ss from my project explorer:
I'm a new Java user and I'm trying to code a simple login page. In first page (NewFile.jsp) users should enter their username and password and should click on "login", or click on "sign up".
1.) If user enters his username and password correctly, a login page (LoginPage.jsp) appears and says "welcome null" but it should show the name of that user instead of null.
2.) In that login page there is an edit button to edit profile information. When I clicked on it, every information is "null" and when I edit them and click on "Submit" button;
HTTP Status 404 - type Status report message description The requested resource () is not available. GlassFish Server Open Source Edition 3.1.2
that message appears.
3.) If I click on "Sign Up" button at the beginning, a registration jsp (SignUpPage.jsp) appears. After filling up text boxes and clicking on "Submit", same Status 404 screen appears.
I created a mysql database called "loginpage" using xampp. In that database there is a table called "users" and it has un, pass, name, surname, email and degree attributes.
try { is = new FileInputStream(file); data = new byte[(int) file.length()]; is.read(data); String extension = ""; int i = file.getName().lastIndexOf('.'); if(i>0)

Everything works except transferring the image file.
I m new to programming and am working on the college project. I have MySQL 5.6.20, Eclipse Kepler and Apache Tomcat 7.0.54. I m trying to retrieve the whole table from MySQL schema into a jsp. All the possible things i can do, i have already tried, but none of them are working.
The following attachment contains the whole project. I have my sql connection code in Sample.java file, which i want to get working in Fetch.jsp on the Submit button click. But it shows the tomcat error as localhost:8080/Sample HTTP Status 404-/Sample ; type Status report; message /Sample; Description The requested resource is not available.

below is my code and this exception was thrown in another page so I created a new page and only imported just a single package still its throwing an exception? Any reasons why?
I develop a little app in javaee6 and jsf2. I have a search page which has a search form with 2 fields and a search button when i click search button the results should be displayed in searchresults page.
Issue: searchresults page is is not displaying records though it fetched records from table I'm able to achieve this using search bean as session scope but i want to use the scope as Requestscope.
how to display results in a PLAIN_MESSAGE. My program is converting hex to decimal and displaying the results. Here's the code:
package pkgfinal; import javax.swing.JOptionPane; import java.util.Scanner; public class Final { public static int Convert(String userInput, int base){ int running_sum = 0;
I am getting Web Page Expired error while clicking the back button of the browser, after submitting a form. The form method is POST. ( I have to keep it that way). I tried this code
I need to process 10000 xml files and verify and insert the data into database. I am loading all the files in the file object and iterating one by one. I am getting the memory issue. How to handle this?
I've got another project for a course and am stuck. I've debugged and tried to figure out where it is breaking, but I just can't find it. I've used this connection code block as well as the contstructors before, but this just won't work. I've got a tab that should send all of the information to a MySql database upon the click of 'Add Employee'. I've given my connection string, the addEmployee(); code, and if needed I can include the subclass code. I've got a superclass 'Employee' and a subclass 'Salaried' that uses four attributes from 'Employee'.
private void btnAddActionPerformed(java.awt.event.ActionEvent evt) { addEmployee(); } public void addEmployee() { int socialSecurity = 0; boolean error = false;
I am having a problem to connect my .exe file to the database(mysql). I used launch4j to convert the jar file to .exe but the jar file can connect to the database when running inside the dist folder. When I run the .exe I am getting this error: No suitable driver found for jdbc:mysql.
I created a database in mysql, but I have problems communicating with the DB in java.
Here is the error :
java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/books at java.sql.DriverManager.getConnection(DriverManager.java:604) at java.sql.DriverManager.getConnection(DriverManager.java:221) at displayauthors.DisplayAuthors.main(DisplayAuthors.java:30) java.lang.NullPointerException
[Code] ....
HERE IS THE CODE
public class DisplayAuthors { // database URL static final String DATABASE_URL = "jdbc:mysql://localhost:3306/books"; // launch the application public static void main( String args[] )
This question is not about syntax but a best way to handle something. What is the best way to store a image into a database? For example converting it into binary etc. I just wanted to get some opinions.
I did an application with jframe which i store member personal info like name, surname etc.But when i save it to Mysql database the values are ??????.I have changed database and table and columns collation to utf8, i checked java encoding it's utf-8 but the problem remains.i have spent hours in google search but nothing that works.
i have a problem, im trying to get some values from a jtable (tabla) and insert them in a mysql database, so i scan the table for some values to know which of the rows i must insert ("s" or "n").
I'm able to insert few rows, but when the last row with "s" or "n" is inserted it launch me a NullPointerException and I dont know why.
