Help me. I am Beginner to RMI.

code on the server side:
rebind("rmi://192.168.41.30:1051/toaster",p1);
run it with:
rmirigistry &

does it related with policy???
and how to configure policy???
i am grateful for your help...

u r right.

System.setProperty("javax.net.ssl.debug","all");
System.out.println("Constructing server implementation...");

this is right..
done well after specifying a port number and ipaddress.

When we compile with rmic skeleton and stub get created then we hav to place stub at each client ???Your remote client applcation need only _Stub.class fiels.
Is there way by which we can know how many clients are connected to the
server and there IP address, can anyone give the code... I guess that you should use a RMI login/logout method to register/unregister your client connection information into a databse or a simple static Hashtable(Vector) object.

Help needed to move a java.rmi.Remote object.....

Hi,
I have an object extending java.rmi.Remote on a server. I want to get it onto a client (ie the actual object, not a reference to the object on the server).
The catch (isn't there always one):
The client must only get class definitions/interface definitions from the java.rmi.server.codebase
(ie I don't want to use a network classloader).
Anyone any ideas?
Kev.

If you have a class that implements java.rmi.Remote then the objects of that class by definition are available for Remote access (ie, they are passed by reference). Remote objects can't be passed by value. However, if you want objects of a particular class to be passed by value you could have the class implement java.io.Serializable instead of java.rmi.Remote.
Hope this helps.

Urgent help:send image over network using rmi

hi all,
i have few question about send image using rmi.
1) should i use ByteArrayOutputStream to convert image into byte array before i send over network or just use fileinputstream to convert image into byte array like what i have done as below?
public class RemoteServerImpl extends UnicastRemoteObject implements RemoteServer
public RemoteServerImpl() throws RemoteException
public byte[] getimage() throws RemoteException
    try{
       // capture the whole screen
       BufferedImage screencapture = new Robot().createScreenCapture(new     Rectangle(Toolkit.getDefaultToolkit().getScreenSize()) );
       // Save as JPEG
       File file = new File("screencapture.jpg");
       ImageIO.write(screencapture, "jpg", file);
        byte[] fileByteContent = null;
       fileByteContent = getImageStream("screencapture.jpg");
       return fileByteContent;
    catch(IOException ex)
public byte[] getImageStream(String fname) // local method
    String fileName = fname;
    FileInputStream fileInputStream = null;
    byte[] fileByteContent = null;
      try
        int count = 0;
        fileInputStream = new FileInputStream(fileName); // Obtains input bytes from a file.
        fileByteContent = new byte[fileInputStream.available()]; // Assign size to byte array.
        while (fileInputStream.available()>0)   // Correcting file content bytes, and put them into the byte array.
           fileByteContent[count]=(byte)fileInputStream.read();
           count++;
       catch (IOException fnfe)
     return fileByteContent;
}2)if what i done is wrong,can somebody give me guide?else if correct ,then how can i rebuild the image from the byte array and put it in a JLable?i now must use FileOuputStream but how?can anyone answer me or simple code?
thanks in advance..

Hi! well a had the same problem sending an image trough RMI.. To solve this i just read the image file into a byte Array and send the array to the client, and then the client creates an imegeIcon from the byte Array containing the image.. Below is the example function ton read the file to a byte Array (on the server) and the function to convert it to a an imageIcon (on the client).
//      Returns the contents of the file in a byte array.
    public static byte[] getBytesFromFile(File file) throws IOException {
        InputStream is = new FileInputStream(file);
        // Get the size of the file
        long length = file.length();
        // You cannot create an array using a long type.
        // It needs to be an int type.
        // Before converting to an int type, check
        // to ensure that file is not larger than Integer.MAX_VALUE.
        if (length > Integer.MAX_VALUE) {
            // File is too large
        // Create the byte array to hold the data
        byte[] bytes = new byte[(int)length];
        // Read in the bytes
        int offset = 0;
        int numRead = 0;
        while (offset < bytes.length
               && (numRead=is.read(bytes, offset, bytes.length-offset)) >= 0) {
            offset += numRead;
        // Ensure all the bytes have been read in
        if (offset < bytes.length) {
            throw new IOException("Could not completely read file "+file.getName());
        // Close the input stream and return bytes
        is.close();
        return bytes;
    }to use this function simply use something like this
public byte[] getImage(){
byte[] imageData;
          File file = new File("pic.jpg");
          // Change pic.jpg for the name of your file (duh)
          try{
               imageData = getBytesFromFile(file);
               // Send to client via RMI
                        return imageData;
          }catch(IOException ioe){
                       // Handle exception
                       return null; // or whatever you want..
}and then on the client you could call a function like this
public ImageIcon getImageFromServer(){
     try{
          // get the image from the RMI server
          byte[] imgBytes = myServerObject.getImage();
          // Create an imageIcon from the Array of bytes
          ImageIcon ii = new ImageIcon(imgBytes);
          return ii;
     }catch(Exception e){
          // Handle some error..
          // If yo get here probably something went wrong with the server
          // like File Not Found or something like that..
          e.printStackTrace();
          return null;
}Hope it helps you..

Help for a baffled beginner

Ive just installed Oracle Express to help me go through a phase test. Ive created 3 tables under the SYSTEM username that I started the database with. Ive populated the tables with some data
Now whenever I try and enter any SELECT command it tells me
ORA-00942: table or view does not exist
Now a quick look on google tells me this is most likley that I don't have permission...however, I can't see what I can do to change that, I am the only user. If I create a new admin and recreate the tables it tells me the same.
Also, infuriatingly, it tells me that the 'show tables' is not a valid SQL command so I cannot make sure I am typing it correctly. Although obviously I have gone back into the object browser to check countless times.
Please help me out! Im assuming its something small, but google is huge and I don't even know where to begin with this.
Thanks
Mike

Im not using the command prompt, oracle express 10g's menu to create everything.
However the sql for the existing tables is
CREATE TABLE " Employee"
(     "id" NUMBER NOT NULL ENABLE,
     "name" CHAR(100) NOT NULL ENABLE,
     CONSTRAINT " Employee_PK" PRIMARY KEY ("id") ENABLE
CREATE TABLE "Car"
(     "regNo" VARCHAR2(10) NOT NULL ENABLE,
     "distanceInKm" NUMBER NOT NULL ENABLE,
     "kmPerLiter" NUMBER NOT NULL ENABLE,
     CONSTRAINT "Car_PK" PRIMARY KEY ("regNo") ENABLE
These are for the 2 tables I have managed to create under Mike.
There is a 3rd with 2 foreign keys referencing the above tables and for some reaso, even tho it was possible before under SYSTEM, yet do not exist under Mike, I cannot recreate it
When I log back in under system, the above two tables are still there (as I created them earlier) and also the one I mention above that I did successfully create under system
CREATE TABLE "TravelCost"
(     "journeyId" CHAR(10) NOT NULL ENABLE,
     "carRegNo" CHAR(10) NOT NULL ENABLE,
     "employeeId" CHAR(10) NOT NULL ENABLE,
     "occurred" DATE NOT NULL ENABLE,
     "distanceInKm" NUMBER NOT NULL ENABLE,
     CONSTRAINT "TravelCost_PK" PRIMARY KEY ("journeyId") ENABLE,
     CONSTRAINT "TRAVELCOST_FK" FOREIGN KEY ("carRegNo")
     REFERENCES "CAR" ("REGNO") ENABLE,
     CONSTRAINT "TRAVELCOST_FK2" FOREIGN KEY ("employeeId")
     REFERENCES "EMPLOYEE" ("ID") ENABLE
But I constantly get the 'table doesnt exist'.
Apologies for my wirting, Im in rush and I have a new wireless keyboard thats abysmal

DIV Confusion... Basic help for a measly beginner

Hi all..
Tried   searching but couldn't find anything - perhaps due to my lack of   knowledge of what terms to search for, so apologies if something like   this has been posted :S
I am making my first website   myself after watching and learning from others. Everything is going   great... except I am having trouble getting my footer div to stick to   the bottom of my browser window but still stick to the white content area. I have tried using fixes on the internet but I'm not quite sure where to put bits of code...
You can view my site (in progress) here:

Can anyone help please?!

Help with program! (Beginner)

Here is what I'm trying to do:
lo : Smallest. Write a program that allows a user to enter a series of positive integers with a -99 to signal the end of the series. The program should then display the smallest of the numbers in the series. Do not use a bogus value for the smallest to begin the program. Use the first value in the data list (if any) to initialize your smallest. This program must have only one programmer-defined method other than main which outputs user directions to the console about how the program works (and that -99 is to be used to end the input). Note that an empty list is possible and should not confuse your program! After displaying directions to the console, use GUI for the remaining input and output. Try out your program on the following lists:
10, 3, 8, 2, -99 (lo = 2)
-99 (ouput should be: "no numbers, no lo")
4, 6, 1, 106, 22, -99 (lo = 1)
So far, I've established that...
loop, probably do/while
get input from user, input
if input != "-99",
set list[i] (array) = input
if input == "-99"
set list[i] = input (makes it easy to terminate your loop through the array and to tell if it is otherwise emtpy)
sort through array, comparing two elements of the array, keep lowest and compare to next available, till -99 found
print as necessary
- This is what my friend has told me so far, but I'm not sure what he means by 'set list[i] (array) = unput.
Please help! Either respond here or my screen name (AIM) is Bionix12

A little help with a design (Beginner)

Hey, I just started flash today and im trying to make this
"wave" of pictures for my website through flash, I made this
picture in about 5 seconds so dont leave complaints please : D
http://img148.imageshack.us/img148/3788/22347390ii7.gif
i would like to insert pictures in the middle there that
would follow that path and keep repeating, is there any way of
doing this?
-thanks in advance

Hi Swordmaster93,
Rovers15's suggestion to use Motion Guides would do exactly
what you need for your slide.
I don't know if the tutorial link he gave has this little bit
of info, but just incase it doesnt....here it is...
with motion guides, there is a separate option in your
Properties Pannel, which allows for the movieClips to rotate
according to the path it follows. Which is exactly what you want,
im guessing.
anyway, the option in the Properties Pannel is " Orient to
path "
hope that helps.

(beginner) Need help with a client [Beginner]

Hi, i'm danny and i'm following tutorials and lessons, and i created my own server and i tried to make my own webclient. My Teacher send me a webclient and he said that i only have to change the ip adress into mines (runescapeworld143.zapto.org) and compile it. The whole problem is now my teacher is on holiday and i called him if he would help me he said that i must ask it to the forums of oracle, so here is my question.
Ok the source is here if you wanna download it [http://updatedannyskape.webs.com/client.jar.src.zip]
My teacher say's that the current ip = 188.165.201.65:port43594
and you have to change it in you're ip adress (runescapeworld143.zapto.org)
but the problem is now i searched the whole document for 188.165.201.65 but i can't find it, can somebody help me out where i can find this?
I also tried to compile the source but there are over the 100 errors
Maybe this is because i created my own compiler ?
I don't know but here is the compiler code
@echo off
cd .
"C:\Program Files\Java\jdk1.6.0_20\bin\javac.exe" -sourcepath scr/*.java

Help need to know about JSP-RMI connection

Hi All...
Can anyone send me any tutorial/link about JSP-RMI connection. I need to access a RMI server object from JSP page.Is it possible?
Looking for your responds.....

Hi ...
I didn't get any reply from any one....
Is it possible to make Java Server Pages and RMI work
together -sure, jsp's can make requests to servlets which can then talk to remote objects, then a response can be sent back down to the jsp
to invoke a method on a server object from a JSP? And
if, does
someone know of a good tutorial, article etc., on
this matter?hmm, Google, JSP Tutorial, RMI Tutorial, etc.

Help for a complete beginner!

Hello,
I want to apologize in advance for how little I know on this topic, and about programming together. I am not asking for myself, but to give some advice to a young family member of mine. He works with a company that uses a ColdFusion website, and we were speaking the other day about how the company is looking to eventually hire a new ColdFusion programmer.
Here is the problem for my nephew: he doesn't have any programming experience. He is very computer savvy for a young guy, and he is very interested in going after this, but he told me he doesn't know where to begin. I took the obvious course and said "aren't there such things as ColdFusion classes?" but he seems to think it is not so simple as that - like you can't just jump in as a total beginner into working with ColdFusion?
So I thought I would do a little research. If you were just starting out, and were looking to eventually develop and program a coldfusion website, how would you start? What steps would you take (the more detailed the better)? Someone told me "he should start out by learning HTML", but if you could even break that down more - how would you go about learning HTML? If you have any more questions for me about my nephew, i'd be happy to answer them.
Thanks!

Learning HTML would be a good start in contextualising how web pages work, and therefore what ColdFusion code will be needing to do.
FInding HTML tutorials is easy: just google "introduction to HTML" or "HTML tutorial" or something. If you prefer printed books, there'll be a bunch of those available too (search Amazon). I do not know which books are considered good or bad in this context, but the user comments and votes should be a good indication.
As for learning ColdFusion, just leaping into a course might not be the best bet for your newphew. Way back when I did the ColdFusion Fasttrack course without ever having used (or seen) CFML before, and found it easy, but I did have a background of doing the odd bit of programming, so I was at least familiar with basic principles. If he doesn't have any pre-existing programming knowledge, it might not be the best way to start.
The only printed CF book of note (that I'm aware of) is the CFWACK. I've not looked at one for years, and cannot remember whether it's intended as a learning tool, or just as a reference. Someone else can perhaps comment on that.
There are a bunch of matches for "coldfusion tutorials" on Google, of varying age and quality: they're probably worth looking at though.
If I was learning a new language, I'd just use online tutorials. If I was going to be learning programming, though, I'd go do a general programming course (like at the local polytech or college or whatever) first. The principles behind programming are more important than the language, IMO.
Of course if he dives into CF and has questions to ask, he can always ask them here.

Help for a cairngorm beginner!

hi!
I've looked for samples on Internet but I've found just the
cairngorm store (src untraceables) and "Hello world" with SOAP.
I understood just a minimum how Cairngorm works but i don't
no what i've to put, where and how, to create a simple application.
I'd like, for example, to add a evt using addCommand() of the
Front Controller and implement the execute() method to do a work
and put in place a Model Locator.
Why not viewing a message on the screen when we click on a
button?
i think it will be a start point without calling a server nor
services.
I'll be very recognizing for your help.

[Beginner] Need Help with my source [Beginner]

Hi, i'm danny and i'm following tutorials and lessons, and i created my own server and i tried to make my own webclient. My Teacher send me a webclient and he said that i only have to change the ip adress into mines (runescapeworld143.zapto.org) and compile it. The whole problem is now my teacher is on holiday and i called him if he would help me he said that i must ask it to the forums of oracle, so here is my question.
Ok the source is here if you wanna download it [http://updatedannyskape.webs.com/client.jar.src.zip]
My teacher say's that the current ip = 188.165.201.65:port43594
and you have to change it in you're ip adress (runescapeworld143.zapto.org)
but the problem is now i searched the whole document for 188.165.201.65 but i can't find it, can somebody help me out where i can find this?
I also tried to compile the source but there are over the 100 errors
Maybe this is because i created my own compiler ?
I don't know but here is the compiler code
@echo off
cd .
"C:\Program Files\Java\jdk1.6.0_20\bin\javac.exe" -sourcepath scr/*.java
pause[Compiler error picture|http://updatedannyskape.webs.com/error.png]
I hope you are able to help me, Already thanks !
