Need help with Java always get error

hey guys need help
this the problem i get :
I go to certain websites and I get this error with firefox.
This Site requires that JavaScript be enabled.
It is enabled.
This is the one of the errors in java script console with firefox.
Error: [Exception... "'Component does not have requested interface' when calling method: [nsIInterfaceRequestor::getInterface]" nsresult: "0x80004002 (NS_NOINTERFACE)" location: "<unknown>" data: no]
I have installed the java script from there home site and did a test and says everything is fine. Any ideas?
please help

Hi 49ers,
Sorry not to have any real idea of how to help you out here, but this is a Java forum, not JavaScript.
Some Firefox expert may stumble across your post and be able to offer some advice (I hope they do) but this isn't really the best place to post such questions.
Try here: http://www.webdeveloper.com/forum/forumdisplay.php?s=&forumid=3
Good luck!
Chris.

New @ RMI need help with java.rmi.UnmarshalException: error unmarshalling

Hi @ all out there,
I'm new with Java RMI and have to write a EventSystem for an college project where clients can subscribe to a topic and get notified when someone publishes a message to the subscribed topic.
At server-side I have a class called EventSystem that provides methods for subscribing and unsubscribing from topics, and also for posting messages (for publishers).
To subscribe i thought that the client must specify the topic and also itself ( means that a client calls in this way: obj.subscribe("mytopic", this).
The EventSystem handles a list of all clients, and whenever a new message is posted it goes trough all clients and invokes the handleMessage(String msg) method that all Clients have to provide.
On my local machine without RMi this concept works just great.
I now tried to get it working using RMI , but I get the following Exception when starting the client (the server starts fine) :

Need help with java.lang.UnsatisfiedLink Error

hello,

hi jonas..
thanks for the reply. actually I set SHLIB_PATH on HP UX which is the equivalent of LD_LIBRARY_PATH and i'm trying to load the library using
System.loadLibrary(..) and i type out the path using System.getProperty to make sure that the path to the library is included.
but still i'm getting the error.
i'd appreciate any suggestions.
thanks in advance.

Need Help With Java Query String

I'm new to Java and I'm passing data via a URL to another page(I'm not using a form). I have been succesfull in decoding the string to return the name value below:
<SCRIPT LANGUAGE="JavaScript">
function decodeSearchString() {
var nameValue = new Array();
var searchStr = unescape(location.search.substring(1));
if (searchStr) {
var formElement = searchStr.split("&");
var tmpArray = new Array();
for (k = 0; k < formElement.length; k++) {
tmpArray = formElement[k].split("=");
nameValue[tmpArray[0]] = tmpArray[1];
return nameValue
var srchData = decodeSearchString();
</SCRIPT>
However, now I need to add the value returned from the above srcipt to the Java script listed below:
<SCRIPT Language="Javascript" SRC="#srchData.link#?open&pID=PAR"> </SCRIPT>
This above script if working will add the HTML from the URL query to the page, but I keep getting a Java Error with this script. Please Help !

I assume you are using a JSP page and not just solely doing Javascript. IF you are using JSP, then read on. Otherwise, I can revisit your script.
To obtain the value of the query string, you would use a method call such as:
String strQuery = request.getQueryString()
Or, to get a single parameter off the query string, you can call:
String strSearchData = request.getParameter("paramname");
Or, if you want all the parameters and values instead of just one long string you can call:
Enumeration enumParamNames = request.getParameterNames();
You can use the above enumeration in combination with getParameter() to get the values.
In order to build your script line and add the query string, you would then do something like this:
<SCRIPT Language="Javascript" SRC="#<%=strSearchData%>.link#?open&pID=PAR"> </SCRIPT>
Notice the <%= %> block in the above code.
I hope that is what you were looking for. Your example is somewhat confusing so I may have answered wrong.

Need help with java J2Se 5.0 upgrade 2

Having problems with Java when playing on Pogo, the Vaults of Atlantis. When loading, I am getting a message that says that I need to remove and download again, java. That it is not working correctly. I did that yesterday, 05/27/05 and am still experiencing the problem but only after signing off from Pogo and AOL and then trying to sign back on again later in the day. I have to shutdown my computer and bring it back up again and then I can load the Vaults of Atlantis. I have noticed that when I do sign-off from Pogo and AOL, that my java cup stays on in my deskbar. Is that supposed to be normal or is it supposed to disappear? If it is supposed to disappear, what can I do to fix that problem?
Please, can anyone help?

Need help with Acrobat Xi installation error

Have tried installation several times. Need help now, considering I am paying for this service!

Thank you for the replies.
Jeff, I will check that link and try what is suggests.
Bill, to answer your questions...
1. This is a CC installation.
2. Yes, I am logged in as the admin and I have no anti-virus other than Microsoft Essentials enabled.
3. This is a download installation.
To give even more info that might help, I am using a Windows 7 machine with more than enough capability to run CC. I had installed Photoshop, Illustrator, among other apps successfully. I then tried the Acrobat XI installation. Acrobat XI downloaded and extracted, but when it started installing it froze around 50% and then I received the installation failed error from Windows. Once that was confirmed the CC install progress finishes but shows failure. The More Info reveals the error I pasted in above. Afterward, none of the CC apps worked properly and had to be uninstalled. So, next I installed the CC downloader and tried to start installing Acrobat XI first but the same error occurred. That's when I got frustrated and posted my original message. My limited knowledge leads me to think the error issue lies in the AcroPro.msi file but I have no idea what that is or how to find, correct, or install it.
Thanks again for any help you can provide. I'm really frustrated that I'm paying for something that I can't use.

Need help with java will even pay

I need extreme help. I just don't have time lately to write these programs and I have fallen extremely behind. Basically all I need is to pass this class and right now until I can get some more help I just can't make the deadlines. If someone could help me I will pay you just like a tutor.
Requirements for Lab.
You will need to develop a variety of classes for this lab. Specifically, you need to create:
+1. a "PersonGUI" class that displays fields for a person's: firstName, lastName, identificationNum, and sex.+
+2. a "StudentGUI" class that provides Java components for the entry of: classification (freshman, sophomore, junior, senior, or graduate student), and Checkboxes for (a student being in the Honor's program and/or in the ROTC).+
+3. a "FacultyGUI" class that provides Java components for the entry of: rank (instructor, assistant, associate, or full professor), years of service, and salary.+
+4. a "Statistics" class that, when instantiated, creates an object containing an instance variable for each of the the statistical values outlined below. (Each of these instance variables should be declared to be "private".)+
Your main Lab6 class should provide a means for the user to:
+1. Specify the kind of personal data to be entered (Student or Faculty), and+
+2. Then, depending on the choice made, appropriate fields should be displayed to allow the user to input appropriate information for the type of personal data being entered, and+
+3. Controls that support the following functionality:+
* a "CANCEL" control that will terminate any operation currently being performed and return the user to the "Startup" window.
* a "SAVE" control that will cause the just entered data to be harvested from the graphical user interface and the appropriate statistics to be updated. Note: this function may NOT be performed if any of the student or faculty member data fields have not been filled in.
* a "RESET" control that will erase all information recorded to date (i.e., all summary variables are reset to zero).
* a "CLEAR" control that will erase all fields for the personal data currently being entered.
* and a "DISPLAY TOTALS" control that will display, when pressed, the following data:
+1. For students:+
+1. total number of students entered so far,+
+2. number who are male and number who are female,+
+3. number of freshmen, sophomores, juniors, seniors, and graduate students,+
+4. number of students who are in the Honor's program and number who are in the ROTC.+
+2. For faculty:+
+1. total number of faculty entered so far,+
+2. number who are male and number who are female,+
+3. the name and salary of the highest paid faculty member on campus.+
Your program should validate numeric data to the extent:
+1. no numeric field (id number, years of service, or salary) may be left blank by the user. If done so, the user should be alerted to enter a numeric value.+
+2. when the user enters a "years of service" value for a faculty member - the value entered should be verified to be a valid integer value in the range 1 to 50. If the data entered is outside the valid range or is not a valid integer - your program should reject the value and prompt the user that invalid data has been entered and that a new value is necessary.+
+3. when a faculty salary is entered, verify that it is a floating-point value in the range $35,000 to $200,000. Handle invalid data as described above.+
+4. Similarly, if an invalid integer value is entered for the identification number, the value should be rejected and the user prompted to reenter.+
+5. Information should not be saved, nor should statistical values be updated, until all numeric data has been validated.+
Note -- You will be graded on appropriate use of instance vs. local variables, use of methods, and passing parameters and returning appropriate values.
+1. The 'Statistics" class MUST provide "mutator" and "accessor" methods that are required to access values or to modify the values of any variable. REMEMBER ALL VARIABLES ARE DECLARED TO BE "private"!!+
+2. You should implement methods to verify the data, as detailed above. The methods should return boolean values indicating whether the data is acceptable or not.+

Sorry to hear about your problems - lack of time, having fallen behind, imminent failure etc - but none of these are Java problems.
This site deals with Java problems: compiler or runtime behaviour that people can't understand. If you have problems of that sort (and especially if solving those problems would help with the problems you did describe) then post them.
Otherwise you would seem to be in the wrong place.

Need help with java

ok so i have a midterm and need help this question that is gonna be on the midterm. i dont know how to do it and its worth 16 marks!!!! here it is
the UW Orchestra wants to produce a CD containing all the pieces of music
from its upcoming concert. In order to do that, it needs to calculate the total length of time for the
CD. In addition, the conductor wishes to know which piece of music has the longest duration.
Sample output for the program.
The Swan (3.88)
The Bee (0.98)
Claire de Lune (6.02)
Liebesfreund (3.38)
Ragtime (3.48)
The total time for the CD is 18.74 minutes.
The longest piece is Claire de Lune.
Do not include the HTML that is required to embed the program into a Web page (that is, show
only what you would write between <script> and </script> tags).
[4 marks] In the following space, define a function, Print, that takes two parameters, Title and
Length, and outputs a line of text such that Title appears in italics, followed by Length in
parentheses. The function also returns the value of Length.
For example, Print("My World",30) will output the line
My World (30)
and return the value 30.
Put your JavaScript program for the remainder of this question in the space provided on the next
two pages.
[9 marks]. For each piece of music, your program should input the title of the piece and the
duration (in minutes) for that piece, and it should output a line showing those values using the
Print function just defined. After all pieces have been listed, the program should output the
total length of time for the CD, adding in 0.25 minutes between each piece of music (which is
needed on the CD to separate the pieces).
[3 marks] The program should also output the name of the piece that has the longest playing
time.
Use reasonable variable names, indentation and good programming style. Documentation and
comments are not required, but you may add them to explain any assumptions you might want to
make. You need not check that the input is valid, and you may assume that no two pieces have the
same duration.
can anyone help me out! i would be indebt of ur kindness if u can help me out!

This forum is for Java, not JavaScript. The two have nothing to do with each other.
And anyway, this is your studying, so you should try to do it, put forth your best effort, and ask specific questions (on the proper fourm).

Newbie need help wtih Java Applet noinit error

Hi, i am having problem with a making this java applet application run, i am new to java but i am sure that my coding is right, because this what i typed from my java class book. Don't know why when i try to run it is say at the bottom of the windows explorer, "applet class name "noinit"". The code is listed below maybe someone could help me figure this out. I used NetBean to compile it, also I have the latest version of java but could not find a applet that come with the newest version of java so I'm using the j2sdk1.4.2_11 applet, and have added it to my system environment path. Maybe that could be the problem if so where do i get the newest version of the applet, because without doing what i did i could run applets in the first place. My other sample applet sample (demo's) that come with Java runs fine without any problem. Only when i run mine i get the message, "applet class name noinit".

Need help with Java programming installation question

Sorry for my lack of knowledge about Java programming, but:....
A while back I thought I had updated my Java Runtime Environment programming. But I now apparently have two programs installed, perhaps through my not handling the installation properly. Those are:
J2SE Runtime Environment 5.0 update 5.0 (a 118MB file)
and:
Java 2 Runtime Environment, SE v 1.4.2_05 (a 108MB file)
Do I need both of these installed? If not, which should I uninstall?
Or, should I just leave it alone, and not worry about it?
Yeah, I don't have much in the way of technical knowledge...
Any help or advice would be appreciated. Thank you.
Bob VanHorst

Thanks for the feedback. I think I'll do just that. Once in a while I have a problem with Java not bringing up a webcam shot, but when that happens, it seems to be more website based than a general condition.

Need Help with Java XML Pack

I Downloaded the JavaXMLPack-summer-02_01 and am a little unsure about configuration and use...
The documentation says:"
To use the Java XML Pack technologies, you need to set the home directory for each technology as follows:
JAVA_XML_PACK_HOME to the directory where the java xml pack has been installed.
JAXM_HOME to <JAVA_XML_PACK_INSTALL>/java_xml_pack-summer-02_01/jaxm-1.1_01
JAXP_HOME to <JAVA_XML_PACK_INSTALL>/java_xml_pack-summer-02_01/jaxp-1.2_01

JAXRPC_HOME to <JAVA_XML_PACK_INSTALL>/java_xml_pack-ummer-02_01/jaxrpc-1.0_01
but nothing about where to set this...
I tried to set those as environment variables- s�that right???
Next thing:
When I want to use the JAXM Libraries I have to set the .JAR Files as Classpath - Seems strage to me...
And now the Problem:
I compiled the StandeAlone.java Sample from "/jaxm-1.1_01/samples/standalone"
And when I start the class File I get the Error message
java.lang.NoClassDefFoundError: javax/xml/soap/SOAPBody
     at DataExchange.<init>(EOS.java:67)
     at EOS.init(EOS.java:14)
     at sun.applet.AppletPanel.run(AppletPanel.java:341)
     at java.lang.Thread.run(Thread.java:536)

I have been having similar problems. I have set the variables you mentioned in my .bashrc file and set the classpath variable to include them. However the compiler still can't find them and I get a slew of NoClassDefFoundError exceptions when trying to compile code which uses the xml stuff.
The strange thing is that the classpath variable was empty before I added the java xml stuff to it so I don't know how it finds the core java classes. It gets this information from somewhere and if I could find out where this is then I could add the xml stuff to it and everything will be fine.
Any ideas on where java is getting the location of the core classes from?

Need Help with Java Homework

This is my first post here, seeking some help with my java homework. I am required to create a program to write out a receipt for a pizza company: name of company, total number of pizzas, costs (including tax etc), and print out the receipt after taking an order from the customer.
This is a beginner's java class and my book isn't very good at explaining (mainly because it says "will be discussed in ch 14" when we're in ch 1-3 and it's an essential part of the program).
But anyways, if anyone is up right now, would be helpful for some help. I have a general idea of what I wanna do, but the program so far is very messy and incomplete and having trouble getting it to look nice and proper.

well there were two ways of doing this, im only 2 weeks new in java so bear with me.....I was gonna set 3 classes, one appclass, one order form, and one receipt. I was told you can combine the order and receipt in 1 class, but I thought doing 3 woudl be better to help me learn more...anyways, I haven't worked on the appclass yet, but for the order I have a very messy set of codes. I know that it's wrong but it's a start, im looking for any input cause the book does not explain very much.
For the order class, I will be doing showinputdialog boxes for how many pizzas, the sizes, and the toppings. Here is what I have so far ( i know it is VERY messy and disorganized but I am a bit lost in where I should go next):
* @author AlexNguyen
* To take the order with number of pizzas and toppings
package project2;
import javax.swing.JOptionPane;
public class Order {
     public int NumberOfPizzas;
     public char Pepperoni;
     public char Sausage;
     public char Cheese;
     public Order(int n) {
     NumberOfPizzas = n;
     JOptionPane.showInputDialog("Enter Number of Pizzas"));
String ptype; {
     public void start();
     public void takeOrder();
     public void writeReceipt();
          public void takeOrder();
          ptype = Topping
public String selectPizza(char P, char S, char C) {
     Pepperoni = P;
     Sausage = S;
     Cheese = C;
public void numPizza(int numberOfPizzas) {
     num = numberOfPizzas;
JOptionPane.showInputDialog("Topping for Pizza?");
JOptionPane.showInputDialog("Pizza Size?");
JOptionPane.showInputDialog("Number of Pizzas?");
}
