Application Web Java To Insert Data Into Database Oracle From XML Files
Oct 27, 2014
I want to create an application wich can handle xml files ( display xml files's data on a html page) + insert those data into an oracle database.
I'm new to that, it a project for my internship. wich API is the most appropriate for that ( Jdom or Xstream or other), wich framework i can use ( there is only 3 IHM : connexion, upload file, display data, confirmation insertion data)?
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'm creating a web applicaion. for that i want to create a registration page. and this registration details have to be stored in the database.
I'm getting the below error while trying to send the data ...
The requested resource (/cmd/InsertRegtodb) is not available.
Here cmd is project name and InsertRegtodb is servlet name.
Actually the servlet is present is the mentioned address. but it is not connecting to it
There is one more servlet in the same folder and which is accessible from another jsp. But this servlet is not accessible even though i have used same code as it is used for the servlet which worked for me previously...
I can insert data to table by using JSP Scriptlet easily but I have a hard time with servlet.
public class UsertToDatabase() { public boolean inserUser(String name, String email, String pwd) throws SQLException { PreparedStatement pstmt = null; boolean flag = false; System.out.println("start"); openConn(); System.out.println("start_1"); if(conn == null) {
[code]....
I am positive that the above code function fine. The problem is whenever I call UserToDB() class inside the servlet, and I got this error: java.lang.ClassNotFoundException: org.postgresql.
Driver which mean that my conn (connection) is not connected to the database but I have ensure to do so by calling openConn() before start the transaction.
I need my java program to insert data into my access database. I get no errors in my code, but it never inserts, deletes the data in my database. Here is my code:
import java.awt.*; import java.awt.event.*; import java.sql.*; public class INS extends Frame implements ActionListener{ Frame f; Label l1, l2; TextField t1, t2; Button b1, b2, b3, b4, b5; Connection c;
I have tried this code to insert into datbase if not exists but i get an Exception in thread "main" com.mysql.jdbc. exceptions.jdbc4. MySQL SyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE NOT EXISTS (SELECT teamName FROM Teams WHERE teamName = teamName) LIMIT 1' at line 1
stmt.executeUpdate("INSERT INTO Teams(teamId,teamName,league) VALUES ("+i+",'"+loser+"','"+league2+"')WHERE NOT EXISTS (SELECT teamId,teamName,league FROM Teams WHERE teamName = teamName) LIMIT 1;");
I need getting detailed examples about how I can read/insert into database using JSF code for its different components. I am a beginner in JSF and I have the basics, however, I need the best source which it has useful, easy and detailed steps to understand the techniques for connecting to the DB and how to insert or read data from the database.
I tried to search, but I found the lessons are not useful or not described in details.
I have written java program which can extract online data from url and i want to store it in data base in new token row in table so than i can use in my application . how could it be done using type4 drive ..
These are my code ...
import javax.swing.text.html.parser.*; import javax.swing.text.html.*; import javax.swing.text.*; import java.io.*; import java.util.StringTokenizer; import java.net.*; public class ParseTest extends HTMLEditorKit.ParserCallback {
I am trying to develop a new web application which takes in data from a form and stores data in a database.I have included all the three files join.jsp(the form which takes in data),reg.java(servlet) and JavaConncetDb(method which connects db and servlet). I get a 404 error when i try load the web application.
My file structure in eclipse
The error I am getting
join.jsp <%@ 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"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
I am developing my first Java application and the database I use is MySQL. I have created two separate buttons; one to insert new data into my database and the other to update the database when changes are made.
Each button is working perfectly, but I now want to combine both functions into just the save button. Thus, whether I am entering new data or modifying existing data, the save button should use an IF ELSE condition to decide whether to use the INSERT or UPDATE command.
My problem is, how do I write this IF ELSE statement? What should be the condition? For example;
IF(what? ){ String sql ="Insert into Table1 (classID,className,counselorID,startDate,endDate) values (?,?,?,?,?)"; }ELSE{ String sql2 = "update Table1 set classID = '"+value1+"',className='"+value2+"',counselorID='"+value3+"',startDate='"+value4+"',endDate='"+value5+"' where classID = '"+value1+"'"; }
I need a java program for getting name and address matching from oracle database. I need get all the customer name and address belonging to same person even if there is slight name and address changes are there.

I am unable to get a best code for this and trying since long time.
My query retrieves more than 5000 records from Oracle database. I want to display the records 100 per page. I know it is called pagination. Any detailed styp-by-guide or tutorial or example available?
I am using itext to create pdf files , i have filtered some records (preferably i can say around 90) which has the option to open pdf for individual record. Now I need to open all the pdf's of filtered records on a single click , without asking for a open dialogue box. How to go about this ??
I want to store an image/file into oracle database using jsp.
I have written code to store data when am running in my machine it is working fine, but not working in server throwing an error saying that "The system cannot find the file specified."
I have small Java code, which execute every day and checks for data in database using Cronj Schedular and everything works fine, but recently I have observed that, it is failing due to
java.sql.SQLException: No suitable driver found for jdbc:oracle:thin:@160.110.xx.xxx:1521/test
At the same time, when I run my test code to check Database connectivity that works fine without above exception. I'm unable to figure it out. Although, there was just slight code change, but that was nowhere related to Database or Database connection.
dbconf.java public class dbconf { private Connection connect; private String connstr; public Connection getConnection() throws SQLException { connstr = "jdbc:oracle:thin:@160.110.xx.xxx:1521/test";

I have java application used to manage a sqlite database (add new records, search .....) I already have everything and I convert it to jar file but the question is how to burn it to cd with the sqlite database . I mean we need to change the database URL for connection class. My question is there any programs would combine my database + my jar file and make it exe file ?
or i should manually change my database url in connection class ? (if yes what should i write knowing that my database and my jar file will be burnt to a cd). I searched online but i could not found any one related sqlite database or at least a clear one . I already has my jar file but if i moved the database from its directory it will not work ...
I have to store data I've pulled from the web i wanted to do this by storing it in a database but after looking at some tutorials i'm not sure if its possible as the databases don't seem to run with the application but instead run as an independent entity.if its possible to have a database in the java application so it runs when the application runs.
I developed an application that is accessing some property files. The condition was that the user should be able to modify the content or parameters of those property file.How can I distribute the application using Java web start that also includes those property file in the client side?
