For a first project sneak check this: Tutorial "Creating and Running an Application Client on the GlassFish Server"[^]

And here is a quick start guide:
Oracle GlassFish Server 3.0.1 Quick Start Guide[^]

and here is a WIKI:
INstalling Glasfish[^]

I'm not used to Glassfish, more the Tomcat user. but the Glassfish Server should also be visible on your machine using http://localhost:8080 in your browser.

And what is PDU format?

I must get a clever new signature for 2011.

Shift operations with float and double

I know PDU just as a Protocol Data Unit[^]

is this what you're thinking about?

And please explain your problem some more.

Hello All,

I have created a simple Web Service in Java, which has only one class containing 4 functions, Add, Subtract, Multiply and Divide. Now I want to publish this Web Service on Tomcat Server. I am able to do it on my Localhost through Eclipse.

Can please any one tell me how should I deploy this web service as a WAR on different server and how can I access this from another server/client. In short, where I can get the URL of the web service.

Any help in this regard is appreciated.

--Thanks
Sameer

Hello,
I need to know hot to use shift operators << and >> in Java with float and double types. I tried to use them but I got compile error. I needed it for serialization data e.g. sending over the streams.

Richard MacCutchan7-Mar-11 6:53

7-Mar-11 6:53

I do not think that Java streams allow these operators, << and >> are shift operators which is why you get compile errors.

Both Double and Float support the longValue() method which will return you a long primitive (if it's in the range of long). The other option for bit manipulation is to use the toHexString() method on Double or Float.

This may be a dumb question but what does bit shifting have to do with serialization? Why would you need to shift the bits in a double value in order to send it over a stream?

I think the OP is getting confused with the stream operators of C++.

I'm assuming that you want to use the bit-representation of the floating point value with the shift operators to create a float from a byte-stream, and vice-versa

The java Float class (here[^]) contains functions:
floatToIntBits, floatToRawIntBits -- Convert from a float to an integer containing the float value's bit representation
intBitsToFloat: Converts an integer value (containing a float value's bit representation) to a Float variable.

So basically you can do something like:

byte[] data = ...;
int rdInt = data[0] | (data[1] << 8) | (data[2] << 16) | (data[3] << 24); // Or the other way round depending on endian-ness.
float rdFloat = Float.intBitsToFloat(rdInt);

... And do the opposite to convert back from float to bytes.

Hi,
I installed Netbeans 6.9 and try to work on Java. at first glance I faced 2 questions?
when you open new project you see Java and java EE. what is the problem between them? what the meaning of enterprise Application?

I would please if some one who has experience help me in this matter.

[ASK] about create file in directori

9-Mar-11 4:28

'at a glance' is the keyword: Java EE at a glance[^]

Java EE @ Wikipedia[^]

So a Java-Project - is a general Java Application of some kind (not further defined).

A Java EE Project is a more specified project with predefined libraries - short and really brief described. Java EE is the counterpart to Microsoft's .net. It's used for advanced projects.

java ee refers to the java enterprise edition, it's a platform for web development.
java usually refers to java standard edition,suitable for develope the basic project like swing, gui.

I have this code for to create file in directory.

public class Coba {
public static void main(String[] args)throws IOException {
Writer writer = null;
try{
String text = "apa kabar";
File f = new File("d:/azhar.txt");
writer = new BufferedWriter(new FileWriter(f));
writer.write(text);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
if (writer != null) {
writer.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
System.out.println("file has been created in directori");
}
}

i want to ask ? how to when i run code mentioned, file in directory open automatically..anyone to help me please ?? Smile | :)

I am note sure what exactly your asking, but having a guess;

The file is automatically opened by the FileWriter providing it is not already opened or cannot be created;

This is as per the specification in the java doc; FileWriter[^]

What about this?..

Runtime.getRuntime().exec ("d:/azhar.txt");

This will do for now
