I am implementing a SSO using NTLM. The steps are:
Step1: Cliente ask for resource
Step2: Server ask for NTLM negotiation
Step 3: Client sends to the server NTLM type 1 message
Step4: Server sends back to the client NTLM type 2 message
Step5: Client sends type 3 message.
The problem I have is in Step 5, when the browser receives the type 2 message, it just stops displaying "IE cannot display the webpage" and sends nothing to the server.
I have checked that I am sending a correctly the type 2 message, using a sniffer I can see the NTLM type 2 message (challenge) and it is well formed (I have test also different flags configuration). I have test also with Firefox and the same behaviour. Server and client are in the same Domain.
I am getting the error message as Exception in thread "main" java.lang.Error: Unresolved compilation problems: NewExcel cannot be resolved to a type for the line NewExcel test = new NewExcel(); in the below code to read the columns from an excelsheet "test.xls". Why I am getting the error message :-
import java.io.File; import java.io.IOException; import jxl.Cell; import jxl.Sheet; import jxl.Workbook; import jxl.read.biff.BiffException; public class ReadExcel
If you have final int i = 1; short s = 1; switch(s) { case i: System.out.println(i); }
it runs fine. Note that the switch expression is of type short (2 bytes) and the case constant is of type int (4 bytes).My question is: Is the type irrelevant as long as the value is within the boundaries of the type of the switch expression?I have the feeling that this is true since:
byte b = 127; final int i = 127; switch(b) { case i: System.out.println(i); }
This runs fine again, but if I change the literal assigned to i to 128, which is out of range for type byte, then the compiler complains.Is it true that in the first example the short variable and in the second example the byte variable (the switch expressions) are first implicitly converted to an int and then compared with the case constants?
Got a problem with generics, which I'm still pretty new at. Here's a program that compiles fine:
import java.util.ArrayList; import javax.swing.JComponent; public class Experiments { public static void main(String[] args) { ListHolder holder = new ListHolder();
[Code] ....
It's useless, but it compiles. If I change Line 14, however, to add a generic type parameter to the ListHolder class, Line 10 no longer compiles:
import java.util.ArrayList; import javax.swing.JComponent; public class Experiments { public static void main(String[] args) { ListHolder holder = new ListHolder();
[Code] ....
I get this error:
Uncompilable source code - incompatible types: java.lang.Object cannot be converted to javax.swing.JComponent at experiments.Experiments.main(Experiments.java:10)
Apparently, the introduction of the type parameter leaves the compiler thinking that aList is of type Object. I can cast it, like this:
JComponent c = ((ArrayList<JComponent>)holder.aList).iterator().next();
That makes the compiler happy, but why is it necessary? How does adding the (unused) type parameter to the ListHolder class end up making the compiler think the aList member of an instance of ListHolder is of type Object?
I'm trying to parse and compare the content of a zip file. However I'm stuck at what SHOULD be a very simple problem, however I can't seem to find a solution. I have done the following:
ZipInputStream zin1 = new ZipInputStream(fin); ZipEntry ze1 = null; fin2 = new FileInputStream(fileName2); ZipInputStream zin2 = new ZipInputStream(fin2); ZipEntry ze2 = null; //fin.close(); ze1 = zin1.getNextEntry(); ze2 = zin2.getNextEntry();
Which gives me the first entry of each zipfile as a ZipEntry type object. I have tried getting the path of the file (inside the zip file) and using this to create a File type object. This does not seem to work though I get:
Exception in thread "main" java.io.FileNotFoundException: My DocumentsmetadatacoreProperties.xml (The system cannot find the file specified) at java.io.FileInputStream.open(Native Method) at java.io.FileInputStream.<init>(Unknown Source) at java.io.FileReader.<init>(Unknown Source)
And this is because I get a null return from trying to create the File file1 = new File(correctLocation);
I guess I cannot access the file inside a zip file this way. So my question is how can I make a ZipEntry type object into a File type object?
The objective of the code is to add new records based on existing records with a partial change to the key. I'm getting "type of the expression must be an array type but it resolved to DstidArray" on dsTidRecTbl[i]
String stMajor = request.getParameter("stMajorVersion"); String stMinor = request.getParameter("stMinorVersion"); String stPatch = request.getParameter("stPatchVersion"); StringBuffer stKeySB = new StringBuffer(stMajor+stMinor+stPatch); String stKey = new String(stKeySB.toString()); DstidArray dsTidRecTbl = new DstidArray(stKey); request.setAttribute("dsTidRecTbl", dsTidRecTbl);
import java.awt.*; import javax.swing.*; public class InstantMessageFrame extends JFrame { private JList friends; private JTextField message; private JButton send;
[code]...
1. Open the source code file of your InstantMessageFrame class from Lab 12.2.
2. Add the following three fields to the InstantMessageFrame class: a JTextField named message, a JList named friends, and a JButton named send.
3. Add a method to your InstantMessageFrame class named getMessagePanel()that returns a JPanel and has no parameters. (This method will create a JPanel that will appear in the south border of your JFrame. It will contain a text field in which a message can be entered and a button that sends an instant message to all the friends in the list.)
4. Within getMessagePanel(), instantiate a new JPanel and give it BorderLayout.Assign a message equal to a new JTextField by using the no-argument constructor of JTextField. Assign send to a new JButton,passing in "Send" to the constructor. (This will be the label on the button.)
5. Within getMessagePanel(), add the message text field to the center of the JPanel and add the send button to the east border of the JPanel. The panel is now ready, so return the JPanel reference.
6. Add a method to your InstantMessageFrame class named get-FriendsPane() that returns a JScrollPane and has no parameters.(This method will create a scrollable list that will contain the names of others that you can chat with.)
7. Within getFriendsPane(), assign friends to a new JList by using theno-argument constructor of JList.
8. Within getFriendsPane(), instantiate a new JScrollPane using the following statement: JScrollPane pane = new JScrollPane(friends);
9. The scroll pane is ready, so return the reference pane at the end of getFriendsPane().
10. Within the constructor of InstantMessageFrame, invoke getMessagePanel(),placing the returned panel in the south border of the content pane of InstantMessageFrame.An Introduction to GUI Programming 399
11. Within the constructor of InstantMessageFrame, invoke get-FriendsPane(), placing the returned scroll pane in the center of the content pane of InstantMessageFrame.
12. Save, compile, and run the InstantMessageFrame class.Your InstantMessageFrame now has three visible components: a JList,a JTextField, and a JButton.
I'm very new to java code I'm currently learning about loops I've tried to write this for a statement in the program I'm making but its not working. I keep getting this message
LoanQualifier.java:26: error: illegal start of expression if (salary >0||<=250000) ^ LoanQualifier.java:28: error: illegal start of type if (yearsOnJob >0||<50)
if i send messages as in the code below, is there a way to read only one message, if the client doesn't know how long it is (or if he only knows the maximum length)?in the documentation it says, that the method read(byte[]) reads until no data ist available or end of file is decteted. What does the latter mean? Can i extend the array that i sent by a byte that signals the end? Here is my Code:
Server
public class Server implements Runnable{ ServerSocket server; HashMap<Short,Socket> clients; public Server(){ clients = new HashMap<>();
[code]....
Both are startet in seperate threads. At the moment the first output of the client is "12 bytes read", and then continously "-1 bytes read"(because the server closes).
I am new to the JMS technology. I have written one sample sender and receiver program to pass a string message to the JMS queue and retrieve it back. It is working fine as well. But now, I want to pass a xml file to the JMS queue. Then from there I need to read the XML file and convert it into a Java object Using Jaxb. I know how to convert an XML into java object using Jaxb. But i am unable to send the XML file as a jms message to the listener.
I want to send a message to a specific client in a server. This is my code and what I tried(I have only given you 3 classes in which I believe I have the problem).
TextClient: import java.io.*; import java.net.*; import java.util.ArrayList; import java.util.Scanner; import java.util.concurrent.TimeUnit; public class TextClient { public TextClient() {
Just want to ask, for example I have message_en_US.properties and message_en_SG.properties.And the web is currently using the SG property but one property is not exist on it, can I just redirect to use the US property?
I wrote stand alone program to post message to IBM MQ , not sure if it posted to queue i see these Another 2,102 character(s) omitted is that mean it didnt post complete message? do i have to increase capacity of text size
I want to split string in such a way that I should get the content before "?" in an another variable. I tried various way but some how I am not getting expected behavior.
In vb.Net, when I do the code msgbox("hello world") and put it in a loop, it will execute that command and show a new messagebox for every time the code goes through the loop. I am wanting to do something similar with java but I'm afraid I don't know how.I know that the following code will display a messagebox as I am describing it
2) It will only display the first message box and when you press ok, the other message boxes will be disregarded and not displayed (I'm assuming because of the hang).
I have a servlet that adds entries to a table and when there is a duplicate it redirects to an error page and I'd like to make it display the duplicate entry id.The problem is when I try to get the parameter and show the error (the duplicate entry id) on my jsp error page it shows null instead of the appropriate number.this is my servlet:
As a part-time student, you took two courses last term. Write a Java program that calculates and displays your grade point average (GPA) for the term. Your program should prompt the user to enter the grade and credit hours for each course. This information should then be displayed with the lowest grade first, and the GPA for the term should be calculated and displayed. A warning message should be printed if the GPA is less 2.0 and a congratulatory message if the GPA is 3.5 or above.
