JSF :: IllegalState Exception From Backing Bean Redirect To External Site
Dec 11, 2014
I am using a command button to post a form to backing bean method. At the end of that method I am attempting to redirect to an external site after setting various options in the response. I get an IllegalState Exception because of the redirect.

I am doing this
@Startup
@Singleton
@ConcurrencyManagement(ConcurrencyManagementType.CONTAINER)
@Lock(LockType.READ)
public class ResourceBean {
[Code] ....
And I call this singleton bean from a stateless session bean like this
@Stateless
public class ClientBean {
@EJB
ResourceBean resource;
public String create(String r)
{
String res=resource.returnString(r);
return res;
}
}
But resource.returnString(r); gives a org.apache.jasper.JasperException: java.lang.NullPointerException I started the glassfish server in debug mode and found out that "resource" was null. but @PostConstruct in singleton does print which means singleton bean exists.
Can we call singleton beans with no interface in such a way form a session bean? I actually want to acquire instance of singleton bean when a client invokes method in Client bean...

I'm new to JSP but I've to use it to grab data coming from an external site, pass data to a Bean, write data in a DB and redirect the user to another page. Follow the JSP page.
<%@page import="EJB.getResponse"%>
<%
long paymentID = Long.parseLong(request.getParameter("paymentid"));
String responsecode = "9999";
getResponse g = new getResponse();
[Code] ....
This is the bean:
@ManagedBean
@RequestScoped
public class getResponse implements Serializable {
private Long paymentId;
private String result;
private String auth;
[Code] ....
On the console I see the prints but I receive the NullPointerException
WARNING: StandardWrapperValve[jsp]: PWC1406: Servlet.service() for servlet jsp threw exception
java.lang.NullPointerException
at EJB.getResponse.printData(getResponse.java:72)

I have seen in some examples like URL... a good design is to have the model and the action methods in one just single bean and the model not to be a separated class but a few properties like this:
public class CustomerBean implements Serializable{
//DI via Spring
CustomerBo customerBo;
[b]public String name;[/b]
[b]public String address;[/b]
//getter and setter methods
[code]...
Some questions:
1. If you are using hibernate or any other ORM like the above example(URL...), why not to use the hibernate pojo bean directly like it represented the form instead of using properties?:
public class CustomerBean implements Serializable{
//DI via Spring
CustomerBo customerBo;
[b]Customer customer;[/b] //represents the properties of a form
//getter and setter methods
public void setCustomerBo(CustomerBo customerBo) {
this.custom
2. Why is it said that JSF represents the purest MVC? Spring separates the model from the view too and Struts does too. I dont really understand it

What is the best way to synchronize a Model representing a complex UI composite w/ a FlowPane's backing list?
Currently I have a change listener on the Model. Upon an add I create a new UI composite and manually add it to the FlowPane's backing list via flowPane.getChildren().add(). Similarly if there is a remove, I iterate over the FlowPane's children, grab the right Node, and remove it. Similarly, if there is a modification detected, I iterate over the FlowPane's children, grab the right Node, remove it, recreate the UI composite, and re-add it to the list. I also need the list to be sorted, so I implemented a UIComposite comparator and call FXCollections.sort() on the FlowPane's backing list. I feel like that is hacky, but it works. It would be cool if I could maintain sort order in my model somehow and have that automatically propogated to the FlowPane's list.
I am correct in assuming that there is no way to have a complex binding in between an ObservableList<CompositeViewModel> and the FlowPane's backing list (ObservableList<T>)?
Some kind of translator that could create a new UIComposite whenever there is a new CompositeViewModel added to the Model list.

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 = "";

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 need fixing an issue in the search textbox in one of the jsp's. I was informed that cross site scripting can be done in the textbox and I kept the below code in my jsp to fix the issue:
Java Code:
searchTerm = request.getParameter("search");
searchTerm = searchTerm.replaceAll("<", "<").replaceAll(">", ">");
searchTerm = searchTerm.replaceAll("[^A-Za-z0-9 ]", "");
searchTerm = searchTerm.replaceAll("eval((.*))", "");
searchTerm = searchTerm.replaceAll("["'][s]*((?i)javascript):(.*)["']", """");
[Code] ....
Now, after applying the above code, the cross site scripting can be done and the problem is that the search can't be done using the textbox and all the time will display none results.

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'm looking for a way to gather data from a site page. all data is shown in the same page... I am trying to get the content and parse it is a bit crazy as data seems to be not organized. Itried to get it as a document but still looks crazy.
As all data is shown very clearly in the page (I would like every row to be an object) I'm sure there is some way to collect this data easily. (the data is from this page: [URL] ....)
I'll attach a snapshot and the content I got from the website.

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
