Keep PrintStream Redirect Across Multiple Scenes
Feb 26, 2015
I have a JavaFX application with multiple scenes. In the application one scene plays the "master" role and the others are loaded according to actions . The issue i have is that i need to redirect all the PrintStream activity to a specific TextArea on the "master" scene, and by "all" i am meaning every PrintStream activity on every scene should be redirected to this specific TextArea . The code i am using on the "master" is :
Node node =primaryStage.getScene().lookup("#ShowInfo");
TextArea ta =(TextArea)node;
FXConsole console = FXConsole.getInstance(ta);
PrintStream ps = new PrintStream(console, true);
System.setOut(ps);
System.setErr(ps);
System.out.println("Test");
I am using the Singleton pattern for the rest of the scenes :
FXConsole console = FXConsole.getInstance(null);
PrintStream ps = new PrintStream(console, true);
System.setOut(ps);
System.setErr(ps);
System.out.print("Hello There");
ps.close();
The issue is that i don't like this implementation ....

I have a JavaFX application with multiple scenes. In this applications one scene plays the role of "master" role and the others are loaded according to actions on the "master" scene(buttons,menu items)
The issue is that i need to redirect all the PrintStream activity to a specific TextArea on the "master" scene...
So everything that normally goes to the console to get redirected to that specific TextArea and this should be global,on every scene that is outputting something it should displayed on the specific TextArea on the "master" scene
The code i am using right now on the "master" scene is :
Node node =primaryStage.getScene().lookup("#ShowInfo");
TextArea ta =(TextArea)node;
FXConsole console = FXConsole.getInstance(ta);
PrintStream ps = new PrintStream(console, true);
System.setOut(ps);
System.setErr(ps);
System.out.println("Test");
For the rest of the scenes i am using the Singleton Pattern to keep the pointing to the Specific TextArea
FXConsole console = FXConsole.getInstance(null);
PrintStream ps = new PrintStream(console, true);
System.setOut(ps);
System.setErr(ps);
System.out.print("Hello There");
ps.close();
The issue is that i don't like this implementation so ...is there a better solution

I know that System is a final class and it cannot be instantiated, out is a static final variable of type PrintStream in System class and println is a method in PrintStream class.Still I don't understand why we use System.out to call println() method.To my knowledge a method can be called using an object reference, in case of static behaviors we use classname. Then why here we are using System.out.println? Can't we just create an object of PrintStream class and call the println() method as PrintStream class can be instantiated.Are there any ways of calling a method apart from those I know(I have mentioned above what I know)?

I have a secured Struts application in WebSphere that uses FORM j_security_check for authentication.There is also a Post Logon "filter" defined which runs some code after a login is processed.The extract from web.xml showing the login configuration and filter is as follows:
<login-config>
<auth-method>FORM</auth-method>
<realm-name>MyRealm</realm-name>
<form-login-config>
<form-login-page>/login.html</form-login-page>
<form-error-page>/error.html</form-error-page>
[code]....
If a user isn't logged into the application and they try to access one of the secured servlets, for example quotes.do, they are directed to the login page to enter their information.If they login successfully, they are then directed to quotes.do, rather than the default "welcome" page. Is there a setting in the web.xml or the post logon filter where I can force j_security_check to ALWAYS go to the default welcome page after a successful login?

String field = "";
String message = "";

(request.getParameter("sadress") != null) &&
(request.getParameter("city") != null) &&
(request.getParameter("state") != null) &&

I use the jsch libraries to create a SHH connection to a remote linux machine. In the next code, given from a tutorial of the JSCH creator, you can see it is implemented shell communication, it is a direct communication from a cmd window. You enter a command from the cmd window and you get aback the results in the cmd window.
Java Code:
String user = "username";
String host = "hostname";
ession session=jsch.getSession(user, host, 22);
String passwd = JOptionPane.showInputDialog("Enter password");
session.setPassword(passwd);
Channel channel=session.openChannel("shell");
session.connect();
channel.setInputStream(System.in);
channel.setOutputStream(System.out); mh_sh_highlight_all('java');
How i can redirect the next two lines to jTextField1 and jTextField2. To give an example i want to sen the command from the jTextField1 and to get the results from the jTextField2.
Java Code:
channel.setInputStream(System.in);
channel.setOutputStream(System.out); mh_sh_highlight_all('java');

I have a simple application ( only 2 JSPs files and one servlet the main components the whole webapp directory is attached ), I am using security constraint to redirect the user to HTTPS instead of HTTP when he submit from first page to the second page.
The problem is when the user submit the first page I get the error HTTP Status 405 - HTTP method GET is not supported by this URL although I m using only POST.
I have traced the firefox browser using httpfox and the result was the first HTTP request was done using POST correctly but after redirect the browser send GET.
This problem appears with FireFOx and IE but doesnot appear with google chrome.

I have a scenario here where the JSF lifecycle is not getting invoked. I have a filter, whose responsibility is to filter only authorized requests.the code of the filter is given below
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
HttpServletRequest httpRequest = (HttpServletRequest)request;
HttpServletResponse httpResponse = (HttpServletResponse)response;
[code]....
now in the else block i am filtering the unauthorized requests, and sending them back to the Login.xhtml page of the application.The problem i am encountering here is that, the images and styles associated with the page are not getting loaded, what i am thinking is that when i am using redirect or forward, the FacesServlet is not getting called, and it is directly going to Login page i.e. no Lifecyle is being called.how to Filter the requests and at same time not lose the styles?

my "test" class:
import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
public class FaceTest
{
public static void main(String[] args)
{
String head = JOptionPane.showInputDialog("Would you like a circle, square, rectangle shaped head?: ");

I have a package (JAR_A) for entity and controller definition, for example:
entity: Entity
controller: EntityController
Then I use this jar in other projects/applications that use the entity.
I want to use the same JAR_A with different persistence unit and different database (in particular, mysql and postgresql) but when I define two persistence unit that include the same class, I have an exception.
So, I comment the other PU and compile the project.
there is a smarter way for use same package with different PU ?

I am trying to launch a GUI to my agent-based model (Repast and Eclipse) so that being able to run the model for many times. I am going to produce input parameters based on different distributions for different runs from GUI. Usually we should use batch file for different runs. However, I want to use GUI for this reason because I have GUI that can take care for one run but not for many runs.

For example, if I have a class called Teacher with the constructor:
public Teacher(double yearsTeaching, boolean isMale, double age)
{
this.yearsTeaching = yearsTeaching;
this.isMale = isMale;
this.age = age;
}
How would I add it to these parameters to my ArrayList in my Tester class?
List<Teacher> teachers = new ArrayList<Teacher>();
