I have written a program student record system but can not save data to view or submit record. Able to run the program but failed to submit record or view pre-submitted records.
I want an app that I can use to save the name, address, item sold, subject discussed and date that I visited someone - in a job similar to a sales rep. I would like to be able to choose how to sort the info so that if I sort by date I can see who hasn't been visited for the longest and start there. If I think of someone's name then of course I want to sort by name.
One of my friends says he works with "php"[? I'm still learning these terms] and everything happens online. I would like it to be an android app so it can be done without an internet connection ....
I have a program that records and reruns network traffic. It was developed in C and runs in my case under Windows 7 Professional but will run almost anywhere. I have observed a lack of stability.
First I have a JAVA stand alone GUI program that runs the program as follows:
g11_bttn_start_script_capture.addSelectionListener(new SelectionAdapter() { @Override public void widgetSelected(SelectionEvent e) {
I am using this image as a reference to learn the Collection interface better and it seems I must be getting confused with the 'ordered/unordered' types. I thought ordered would mean ordering the objects automatically like a TreeSet using the comparable interface so it could be numerically or alphabetically ordered etc..
Java Code:
public static void main(String[] args) { Set hashSet = new HashSet(); hashSet.add(1); hashSet.add(3); hashSet.add(2); for (Object o : hashSet){ System.out.print(o + " "); // Prints: 1,2,3 (Unordered but puts the numbers in order....)
Can we cance/stop a long running database query execution instantly so that we can do any another task.
As i know swing uses a single thread i,e Event Dispatch Thread (EDT), But at the same time we can use Swingworker class for better use of UI. When we use Swingworker class the process goes to a different thread and our basic UI is not Frozen. Infact we can do another task. But what I want is I want to stop of cancel the execution of swingworker thread ( Because I that thread takes long time to execute). How can I do that??
I used ProgressMonitor and in the cancel option i canceled the task ( worker.cancel(true) also i closed the connection and statement for executing the database query using stmt.close() and conn.close() methods.
But it does not work. How to cancel a long running database background process in a Java Swing Program.
I am working on an assignment that requires me to implement 2 methods (add() and remove()) and create an inner class (OrderedListNode). I must use data items of type Comparable. The items should be sorted.
I understand what needs to be done, but I am having a difficult time actually writing the code. I added the main method to check to see if my code works, and it doesn't seem like that is even being read.It compiles without error - it only gives a warning of unchecked or unsafe operations.
Code:
package dataStructures; //This class functions as a linked list, but ensures items are stored in ascending order. public class OrderedLinkedList { //return value for unsuccessful searches private static final OrderedListNode NOT_FOUND = null;
So I have two related tables - Country (Master) Projects (Detail). Country has a OneToMany relationship with Projects. I put a link on my AllProjects.xhtml page. When tyhe link is clicked it uses a data model class to to display the current (clicked) project record (projectRecord object). After editing all the details, the UPDATE button calls a merge method in the DAO class. On the first attempt to update, nothing happens and the record is returned as it is with no errors. If I try updating again, I get:
Is the 'new' keyword in the entity class causing the Inser statement in the DAO because the JPA thinks I want to create a new object therefore invokes INSERT instead of UPDATE?
I am working on web project in java. i have taken buttons in column..and projects is my column..when i click on a button in first row ,i want fetch all information about selected project....so how can i do that?
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub String delete = ("DELETE FROM anagrafica WHERE Nome = ? And Cognome = ?"); ConnectionManager cm = new ConnectionManager(); String Nome = request.getParameter("nome"); String Cognome = request.getParameter("cognome");

and this is my JSP.The problem is easy, when I click on the grid for deleting the record two things happen, or the record is deleted only on JSP but not in my Database or Nothing happens even on my JSP, it is because I don't know how to get values from my jsp and send them to replace the ? in my delete query I tried even to give a name to the <tr> which contains Name and Last name but obviously i guess it works only for input type ex. Textbox.
if (addrecord == true){System.out.printnl("record added");}
I close the interface then enter search for the record i just added using add record method but i do not find it what i am trying to say the added record using my application is not there. The question is how to save this record in the database ...
I am running this method but for some reason I am not able to find the data record, it keeps going to the catch. I have the data.txt file in the same directory as the java file.
public static Games[] gamesRecord(){ Games[] game = new Games[50]; try{ Scanner dataFile = new Scanner(new File("data.txt")); for(int i = 0; i > 50; i++){ game[i].title = dataFile.next(); game[i].releaseDate = dataFile.nextInt(); game[i].redistributions = dataFile.nextInt(); game[i].platformRelease = dataFile.next();
In my java web jsf seam jboss application, I want to add a row in a table with some data fields such as date type, String etc, but one field will be a word attachment, how to do it?
Basically, there is a loop to create some rows of data in a table, before each table row data creation, I will create a word file and saved to a local path(the physical file path is hardcoded), then I will create a table row and attach this word file to that row. the loop will continue until the end of loop.
I'm making a game to teach myself programming java so I can start making android. I have this game I'm making where there will be objects(so far its asteroids) will be falling with a progressive velocity (they will move faster as time goes on). The object is the click on the objects before they hit the bottom. It's still early meaning not all the parts I want to implement are there but it works the way I want it to so far besides my click function.
I'm using the Mouse.isButtonDown(0) to record left click but It lets me hold it down and hover over them instead of clicking on each one. Here is a snippet of the part of the code im talking about :
I uploaded a .jar and a exe file so you can see what I mean [URL] .... -jar [URL] .... -exe
public void update(GameContainer gc, int d) throws SlickException { posX = Mouse.getX(); posY = (Mouse.getY()-height)*-1; timePassed += d; deltaTime= deltaTime();
import java.io.*; public class workhours{ public static void main (String args[]){ try{ BufferedReader breader=new BufferedReader(new InputStreamReader(System.in)); String days[]={"Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"};
I have jFrame where I have to display data from database on button click. There are 4 buttons, first to display the first record in database, last to display the last record in database, next to display the next record and previous to display the previous record. I have done first and last record but what should I do to display the next and previous record.
I am trying to insert a record to a table in my database . I used the same syntax for 2 tables, one does work and the other does not work . I could not find any explanation for this error
"INSERT INTO CustomerRecord (Name, Number, Adress)" +" VALUES(?,?,?)"; //first table working well ps.setString(1,r.getCustomerName()); ps.setString(2,r.getCustomerNumber());
[Code] ....
For some reason one does work but the other does not work it says syntax error near order (table name). I am using sqlite db ...
I need a summary of the steps involve in building java application.I have my source code, already compiled but I don't know the next step to make it run on a particular device. I know of emulator but I need more information.
I created a main class called X and two Y and Z classes.
Y and Z implements Runnable classes.
class X contains a static array A that can be accessed in Y and Z.
The Run () method of the class Y reads an input file and populates the vector A.
The Run () method of the Z class uses data stored into the vector A to process some data.
The objective of using threads in this problem is: as the vector A is filled in the Run () method of class Y, the Run () method of the class Z will processing the received values in the vector A.
to do this I did the following calls in the main method of class X:
ObjectY y = new Y (); Thready thread = new Thread (objectY); threadY.start (); ObjectZ new Z = Z (); Threadz thread = new Thread (objectZ); threadZ.start ();
is that correct? I'm getting the expected results, but dont know if the code is parallelized in fact.
I'm Fresher and i'm new in ATG nd right now working on checkout module.Here I'm trying to take shipping information of user so it is fetching in the shipping information JSP bt when i'm trying to submit that JSP den it's not going to either in SuccessURL or in ErrorURL it's remaining in current JSP.
I'm doing any customization's i'm jst using al Out Of Box Components nd my code is almost same as Out Of Box Code and it is not giving any error also.
I'm attaching my JSP's

I am working on a management gui for a program. I have implemented the start server button. But now I need to get something working so that when I press stop server the javaw.exe process which is running the the other jar file is stopped and ended.
The gui is going to be using a javaw.exe as well and I don't want to end the entire thing.
I just want to end the javaw.exe process that is running the other jar file.
This is my code for starting it:
JButton btnNewButton_2 = new JButton("Start Server"); btnNewButton_2.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { Runtime rt = Runtime.getRuntime(); try { Process pr = rt.exec("java -jar DEDServer_release.jar");
[Code] ....
I just need to figure out what to do to stop it now.
I am looking for a way to have a Servlet (my container is Tomcat) calling a JSP file and processing it in order to retrieve the generated HTML. The compete scenario:
I have virtual shop and whenever a purchase is being carried out, the customer is redirected to a Servlet that post-processes the purchase (list of the items, etc.)
Among all these, the Servlet is also supposed to send me an email about the new purchase. I would like to have nice designed HTML mail and not just a simple plain text notification. I thought of having a designated JSP as a view, and it will only be available from the Servlet container, for this purpose. One way is having the Servlet create an HTTPClient (or any other method of network communication) to my own host and ask for the JSP.
I wonder if there is a simpler way to ask my own container to process a JSP, since I am not really making a request to an outside web application. Something like getServletContext.processAndReturnJsp("mail.jsp")
BTW, if you think my approach is too cumbersome to fill an email with HTML code, it would be great to know of a simpler way.
