I have a blog hosting service (like Wordpress) written in PHP and MySQL, I'm gonna make Java Application for it (Runs on Windows, Linux and ...).
My Questions:
1. Can I use Connector/J to connect to my website database (MySQL)?
2. Which one is better? 1.Connect to website database, 2.Use Socket programming.
I have a Java application this application sits on a Dedicated server and gets information about the machine and run commands on the machine.
I need it so that i can run these commands from pressing buttons on a website. For example i press a button to retrieve CPU info, it goes to the app, and the app sends the CPU info back.
I'm fine with the website and app its just the middle bit. How do i get the app to run commands sent from a webpage. Been ratting my brains for a couple weeks now.
Is it possible to use java to log on to a website? I mean,Ii know how to connect to a website and send commands, but I am not sure how to tell the server that i want to login?
And then after you logged in is it possible to then do something? like, if you logged in to gmail.com you would be able to see your emails?
This might make me look pretty silly but I was curious if there was a way to make a dynamic web page in java. Basically only using pure Java, with only HTML5, CSS and mySQL.

So my program can extract each line from the source code of a website and display it, but realistically I want it to extract each WORD as such from the source code rather than every line. I've looked around online but I don't really know how it's done because I keep getting errors when I use input.read();
How to make it extract each word from the source code?

View Replies View RelatedI've written a java application with several classes all in the same .java file. It works just fine. Now, I've broken it up so that each class has its own .java file. Still works fine. My next step is to put those classes into a package, but I'm not about to get the program to run.The .java source files are all in /home/user/src
I've set the CLASSPATH to /home/user/src..All of the source files have "package com.myfirm.program" on the first line.I compiled the application with:
javac -d . File1.java File2.java File3.java (etc...)
the compiler created the directory: /home/user/src/com/myfirm/program and put all of the .class files in there.So how do I get the program to run? if I run from /home/usr/src
java File1
I get: Exception in thread "main" java.lang.NoClassDefFoundError: File1 (wrong name: com/myfirm/program/Program)
I am working with DLLs in java.
A while ago, I developed an application in VB.net, and I'm trying to "convert" this application to Java. But this VB.net application uses some specific DLLs and I need to use them in my Java application. However, my knowledge in this respect are quite limited in manupulate DLLs on Java.
Up to this point, I can already load the DLL. I've read some documentation on how to use functions that are in the DLL; but I have some doubts. For example, how can I translate this piece of code to Java?
Java Code:
API = New MyDLL.Base
With API
.para1= "1"
.para2= 2
.para3= True
.para4= False

I am currently faced with a task of creating a web application. This application is meant to be accessed by an admin and also a customer. On the customer side the app should prompt the user to fill in an application for of sort and also allow the user to upload a CV to a database.

View Replies View RelatedI am creating a free game in java FX and I would like to offer some advanced features for the supporters (a user of the application that donates to support the project).
But I dont know how to authenticate the user to some network service.i would like to have a hosted application (or light framework) accessible through the network so the user can do something like login with posting credentials (email, password and maybe his IP adress - so I can check if he has passed his credentials to someone else) and to be able to manage the service to add, remove, (un)block users.
I dont know if I should try to create an authentication app myself, as it seams it shouldnt be as hard as I have no roles, no authorization, just a simple authentication. I would like to host it somewhere for free, than maybe if it will be succesful a want to have my own paid light hosting.
I looked for some frameworks, like Apache Shiro, but i would like to know what are the approaches in this kind of donating user authentication, before dwelling into some framework for months just to realize that it is not what I want.
Is there a way to make a exe file, with all dependencies included so it is possible to run the application on any computers without installing any other programs?
View Replies View RelatedI use JDK 1.7.
My java application is blocking from time to time. I have added some log lines and now I know exactly where is blocking, but I have no solution to fix it.
This code runs in a parallel thread, distinct from the main application thread and updates a big JTextArea swing:
try {
....
JTextArea element = (JTextArea)add_containers[objColIndex];
System.out.println("setEditValue start seting text ");
element.setText(VAL);
System.out.println("setEditValue text is set ");
[Code] ....
The code reaches "setEditValue start seting tex" but never reaches "setEditValue text is set". No exception is triggered. The whole application is blocked - main thread and this paralel thread. This section of code is called many times, but in rare cases is blocking without any apparent reason. Sometimes I run the exact same instructions and is blocking and sometimes is working.

I have created an application that I wish for people to be able to run from command line, like so:
java myApp [filename]
Problem is my application uses functions from 3 .Jar files.
Here is how my folder(Assume it is called MyApplication) currently looks:
Application(folder)(contains .class files + source code)
jar1.jar
jar2.jar
jar3.jar
Manifest.txt
I understand I need add some information to the Manifest.txt file but I am struggling in adding stuff to it in the correct format.
Assuming the above folder is called my MyApplication, what I need to put in the Manifest and how to build it all as a Jar File.

View Replies View RelatedOn Form Submit my url changes from
1.localhost:8080/Workflow/admin/GetReports?fname=Form1
to
2.localhost:8080/Workflow/admin/EditReport
Form action is EditReport(Servlet Name).
Now on EditReport i perform the databse operations and forward the request to the GetReports?fname=Formname Servlet using Request Dispatcher.So that i am on the same page which is the first one (1) i started from.
Now Everything works fine on the .jsp page But the url remains unchanged that is the second one (2).
Now if i hit the URL again i.e. localhost:8080/Workflow/admin/EditReport it will give an error.
So how to rewrite the url i.e. from admin/EditReport to /admin/GetReports?fname=Formname after performing all the operations.?
Create a Java Application in NetBeans with the following two classes.
1. A Java class College
o Use the following data fields:
College Name
College City
Number of Tracks
Number of Students
Number of Faculty
Number of Staff
o Implement an empty constructor
o Implement a full constructor
o Implement Setters and Getters (Mutators and Accessors)
o Implement SetAll() method with all data members as parameters
2. Another Java class called CollegeDemo with the main() method:
o In the main():
o Read the values of the fields of 3 colleges from a text file and for
each create a College object.
Filename: colleges.txt
IT Dubai 7 200 50 20
ENG Abudhabi 4 400 60 20
SCIENCE Sharjah 3 300 40 20
First with empty constructor then uses setters.
Second with full constructor (no need to use setters).
Last one with empty constructor and SetAll() setter.
o Display the average number of students for all the 3 colleges.
o Change the value of ‘Number of Students’ in the SCIENCE College to
500, and display the average number of students again.
here my code :
public class Demo {
private String name ;
private String city;
