Servlets :: Java Standalone Program To JSP Communication

Aug 4, 2014

The following programs exist:

1. I have a java application which accepts bio potential data every second or two and stores it in the database. This is a socket server which accepts this data from multiple clients and spawns a new thread for processing it to store in the db.

2. I have a jsp page on tomcat server which reads historic client data from database (stored by application 1) and displays it on the page.

The socket server program in 1.) above is not running inside of tomcat server.The new requirement now is : Display all of the human data coming in live on the jsp page.Now the problem: I will now need to pass the live data from socket server (which is stand alone) to the jsp which is running on a tomcat server.

Possible solutions:

APPROACH 1: Run the socket server in the tomcat instead of stand alone and store the frequently incoming data in a java object so the jsp can access this object every second and display it on a graph.

PROBLEM : The stand alone java application does not need to be included in a tomcat server except for the fact that the jsp needs access to the live data. Also, I have read that this is not the best way.

APPROACH 2: Expose the stand alone java application as a web service and communicate with the jsp using REST architecture.

PROBLEM : The complication of using this method is that it will not have the flexibility offered by websockets or server sent events (SSE) of auto updating the latest data. The jsp will have to keep polling for new data every one second which is also not a very good option.

Swing/AWT/SWT :: Embedded Browser In A Standalone Java App Running On Windows

Aug 24, 2014

I have an embedded browser in a standalone java app running on windows. The browser calls up web pages over the internet with no problem.

import org.eclipse.swt.browser.Browser;
final Browser browser = new Browser(group01, SWT.NONE);
browser.setBounds(0, 0, 1000, 400);
browser.setVisible(true);
browser.pack();
browser.setUrl(texturl.getText());

I have a C executable which captures and documents network traffic. I communicate with it by entering http://27.0.0.1:6500 into any browser (it works with them all). It responds with a simple html form (three buttons, a tick box, a label, and one text box).However I cannot get it to work with the embedded SWT browser.

Java Code Removed Data From XML File

Jul 16, 2014

I tried working with XML today, since that's what my book teaches. First, I read some data about Product objects that are suppose to represent products with a code, description, and price. That worked fine. Then, I tried creating a writeProducts(ArrayList<Product> products) method, and man it did not go well.

How it works is that there is an ArrayList instance variable in the class that keeps track of all of my products after the readProducts method returns that ArrayList from the XML file. When I ran the method I had a lot of stack traces printed. I then checked the file on a web browser and an editor, and saw it was completely empty. Here's the code:

import java.util.ArrayList;
import java.io.*;
import javax.xml.stream.*; // StAX API
public class XMLTesterApp {
private static String productsFilename = "products.xml";
public static void main(String[] args) {
System.out.println("Products list:");

[Code] ....

Java Result: 1

BUILD SUCCESSFUL (total time: 0 seconds) mh_sh_highlight_all('java');

On a side note, is it normal if almost everything I writer has to be debugged?

Read In Java Source Code File As Command Line Argument

Oct 31, 2014

I am trying to complete this question. I understand the most of it but I haven't go a clue to read in the file name.

Full question: Implement a program that reads in a Java source code file and checks to see if it has balanced {}brackets. Your program should use a stack, implemented as a linked list, to check the brackets.

NOTE: you can use a reference called top which points to the head of the list. Your program should run as a command line program and should take a filename as an argument and print one of BALANCED or NOT BALANCED.

For example: c:> java checkBalanced "myProgram.java" BALANCED

Servlets :: Reset URL To JSP File After Servlet Call

Feb 14, 2014

I am a JSP/Servlet newbie currently adding the first servlets to a web site that had been static all along. My local instance worked great but the servlets did not respond on the test instance. Apparently, my hosting service provider requires me to use an invoker servlet mapping.

<servlet-mapping>
<servlet-name>invoker</servlet-name>
<url-pattern>/servlet/*</url-pattern>
</servlet-mapping>

Adding this to local web.xml broke the application but the servlets respond on test instance (when their calls are not preceded by another servlet call). A Servlet fails when it is called immediately after another servlet has been called.

What I saw happening on test is URL for first call is of the form:

xxx.org/<app-name>/servlet/<servlet-name>?Id=1

And URL for the second call became:

xxx.org/<app-name>/servlet/servlet/<servlet-name>?Id=1

The servlets are invoked using "href=servlet/<servlet-name>?Id="

How can I avoid the inclusion of 'servlet' in the URL and reset the URL to the JSP page it navigates to after processing of the servlet?

P.S.: I am also trying to enable the Invoker servlet on local so I can troubleshoot easier. I went through the changes to Tomcat's web.xml and context.xml. However, my local servlets did not respond even after calling them using "href=<servlet-name>?Id=". Is there a way I can check if my invoker is active?

JavaFX 2.0 :: FX Preloader In Standalone App

At the end I just copy and paste the code from section 9.3.4 (the long startup task example) and it still won't work. After starting the application I only see some black screen flickering at the upper left screen and then the main app shows up.
 
What I have done:
 
Using Netbeans 8.0 under Linux(Fedora20 64bit), JDK 1.8u5 ...
 
Here are the two classes - the main app :
 
import javafx.application.Application;
import javafx.application.Platform;
import javafx.application.Preloader.ProgressNotification;

[Code]....
 
On my machine I see only a little black flickering on the left upper screen and then immediately the app is shown...
 
The only way I can get this to run is to set the custom preloader property in the Netbeans-project properties. If you use a maven based project in Netbeans you did not got this option ...

Standalone Taking So Much Time Than Web Application

Oct 29, 2014

I am working on a web-application where i have a functionality which generates reports based on the data from DB. for small amount of data its working nice if the data is huge its taking more time. to avoid this problem i developed a standalone batch where i generated the jar file for the sources in web-application and made a call to the appropriate methods.

But my problem is if web-application takes 10 secs to generate the report but in the case of standalone its taking nearly 3-5 mins to generate the same report. i didn't do much of the changes in code just using the same code as web-application

I am using tomcat 6 application server to run the web-application for standalone using batch commands.....

Swing/AWT/SWT :: Image Redraws Faster Inside Eclipse Than Standalone

Jan 31, 2014

I don't know if this is appropriate to Swing/AWT, or even if this is a Java issue, but I had quite a shock recently. I have been working on a kind of drawing program in which the user can select tiny control rectangles and drag them around, causing the shape of a polygon to change. (They are not implemented as Java Polygons or Shapes because some are one-dimensional). I have gotten it into pretty good shape, so I exported it from Eclipse, my development platform, into a standalone Java application. In the standalone application, each time I drag the mouse, the redrawing shows nasty flickering, as if it's running too slowly. While I was developing the application inside Eclipse, it ran perfectly, with no flickering whatsoever.

What gives? I'd expect that the in-Eclipse runs would be slower, because they're burdened with extra debugging baggage, while the exported standalone version should run faster. But the reverse is the case.
