Deploy Android Application That Connects To Java Server
Aug 25, 2014
I am trying to deploy an android application that connects to a java server. I am doing an apointments system, so the client asks for an apointments with a specific office/doctor. What i did, was to create a java server, using object for the offices, and via sockets it communicates with the android client.
The problem is that when i tried to use my (very demo still) app on my phone and sent it to some friends for testing, i coulnt find a way to have my server on the internet.
So I changed to (or trying to) servlet. But, how to do a client server application with servlets. All tutorials i have seen are more on website clients, but thats not what i need.

I would like to know how we can deploy one Web application on multiple server to share the work between them? My first thought is that we just deploy the same war file on different servers that connect to the same database. However, what will happen when a user enter something like [URL]? How can multiple servers share the same domain name and how the requests from different users are redirected to these different server?

How to deploy Java Swing application as windows software. I have tried the following to do this :
I have created jar file for my project after that created exe file using Launch4j and Advanced installer, exe file produced by both software are working fine but those are placing the jar file inside that exe file, My problem is any one who has that exe file can extract and view the source code by decompiling java class file. Is there any way to deploy java application without decompiling the code.

I have a large scale enterprise application (5 modules) project using RAD, WAS v7, Java EE 6 (EJB 3.1, JPA), ZK framework.
The project is using RAD as IDE. The problem is that it takes too long to deploy (more than 5 min) when changes are made to the EJB's (although the changes are minor in only one file) but when changes are made to zk framework (the web & presentation layer), it is fast to deploy.
Don't know what cause the problem. Is it because of EJB 3.1/ JPA or RAD/ WAS?
Is it happening in other IDE or applcation server also?

How is session maintained in the application server, internally what happens when the user has logged in ? We create a session and store the user details which will be stored in the session object in the server with a unique sessionID which will be validated when the same user login the system again? But how exactly the session is maintained in the Server internally?

At our company we run a third-party Java-based GUI application on one of our Linux server machine, displaying the application to our local Windows work stations using the Cygwin X Server.We noticed a few problems with a new version of this application and was able to narrow it down to the following conditions:
1. Java Swing application running on a UNIX host;
2. Java used is 1.6 (problem not noticed when using Java 1.5)
3. Displaying to Cygwin X server (I've heard other windows-based X servers have the same issue, but I don't have access to any others at this time).
If we run the application natively on Windows, I'm told if the application runs on the Linux host and displays natively to that machine's display there are no problems (although I'm not able to verify this myself).The problems are:
1. Any new frame/dialog is opened in the geographic center of the dual displays, rather than in the middle of one or the other;
2. Any attempt to drag the window to a different location on the display seems to work, but as soon as you let go of the drag, the window snaps back to the original location. This only happens the first time you try to move each window.
3. Drop-down controls (JComboBox, for example) just close back up as soon as you click on them. If you click and drag the mouse to attempt to make a selection, no selection can be made.
Are these known problems using 1.6 on UNIX displaying to Windows-based X Servers?
The only real problem is number 3. I expect that if I put more work into the window placement, I should be able to get past number 1. Number 2 is just a minor annoyance.The following is a simple Java Swing application which when run in the correct environment will exhibit the problems.
import java.awt.EventQueue;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
[code]....

i want to use EJB 3 in my WAS8 application but it doesn't work.First of all i created an remote-interface:
import javax.ejb.Remote;
@Remote
public interface EjbTestRemote {
public void doSth();
}
Then i created a session bean class:
import javax.ejb.Stateless;
@Stateless
public class EjbTest implements EjbTestRemote {
[code]....
But now i want to call the session bean from a normal (no servlet, no ejb) java class but i doesn't work (NamingNotFoundException):
try {
Context ctx = new InitialContext();
EjbTestRemote ejbTestLocal = (EjbTestRemote) ctx.lookup("java:comp/env/EjbTest");
ejbTestLocal.doSth();
} catch (NamingException e) {
e.printStackTrace();
}

a new java executable file which does heavy processing (batch). Development hasn't really started yet and the design phase is just beginning. Now the client is asking us to give them the minimum server specs to be able to run our application..I'm thinking this can't be done without performance testing, which will be after development. Is there a better and faster way to be able to assess this?

I have an application developed in Jsf, hibernate eh-cache. i deployed it on jboss server and users are directly accessing jboss url on port 8080 in internal network. Now problem is, number of users for this application has been increased. This application have one page containing 20 records which gets fetched from cache on jsf page. I have used a4j:poller tag which refreshes this page via ajax call and updates it. Earlier this was working fine but nowadays number of users have been increased. Issue is i get nullpointer exception after some time once i logged in to application and user gets redirected to login page. If user re-logins he gets directed to same page number before logout. There is no reason of throwing null pointer exception and this application works fine in qualification environment. We checked everything,
1) session is still there on server. thing is user gets disconnected from it.
2) Network bandwidth seems to be okay.
3) we have used hibernate eh cache and serialized java classes.
how to troubleshoot and find root cause for this. Some people say that it is due to ajax calls from multiple users and ajax response it getting lost in between.

I have an integer variable called 'selectedname' which is declared as shown below.
public class MainActivity extends Activity implements View.onclickListener, AdapterView.OnItemClickListener {
int selectedname;
So when the app starts an Alert Dialog with two buttons asks the user if they want to tell the first or the last name. The two buttons are 'first' and 'last'.
The problem I'm facing is that in the code the value of selectedname is suppose to change depending on the users choice as shown below.
public void displayWelcome() {
//*other code comes here but it works fine*
AlertDialog.Builder choice = new AlertDialog.Builder(this);
choice.setTitle("Yo!");
choice.setMessage("First name or last");
choice.setPositiveButton("First", new DialogInterface.onclickListener() {
public void onclick(DialogInterface dialog, int whichButton) {
selectedname = 1;

I have a gameengine stil partially in the works for pc made in java, I am attempting a port over to java but certain classes and other fuctions are not available for android that there is in java. this means that my render engine, gameengine and a couple of other clases therefore don't work.
My question is, is there anyway of using the gameengine classes that work into the project so that all i have to do is declare within the engine what i want to export for wheather this is android or java. or importing packages from the game engine project and directly linking with the ability of re-writing the odd few classes that do not work.

I am in search of a library that has been created in JAVA that can be utilized to solve for roots of a nonlinear system of equations. Each equation has 2 variables, x and y, and will need a library that uses higher calculus equations. No ones that just solve for x.
Most of the libraries that have been created to solve nonlinear equations are either in Fortran, C, or Python. There are a few libraries such minpack/scipy. The only libraries that I have been able to find or programming solutions that are in JAVA either require additional programs such as Matlab or are commercial products
I did find one library put together by a professor in Colorado State, but am unsure how to use it. There does not seem to be a way to enter your functions in the code.
Newton Raphson Method - Multivariable(x and y) Page Not Found
How to use this library or find a library that can be used in an android application would be amazing.
