Re: Multi-part data in jsp forms - Java Discussion Boards

to begin with java, if u know c++ is better , but if u don't know c++. u can also learn java. u should first go through java book that is "E.balaguruswamy".

u need jdk1.5/1.7.

internet is the best source to learn self....

A very good way to learn Java is the free course from Stanford Engineering Everywhere:
Programming Abstractions[^]

The instructor Mehram Sahami is simply great!

Hello Uttam Kukadiya,

First you need to learn the basics of the language.. There are many of tutorials available but you might like to take a look at this online resource:

http://www.functionx.com/java/index.htm

There is also the offical site:

http://docs.oracle.com/javase/tutorial/

The most important aspect when learning how to code in a programming language easily, quickly and effectively is writing the code YOURSELF, testing it and just play around with it by experimenting with changing the values and amongst other things. Smile | :)

Best of Luck!

Happy Learning!

You could at least try to find out the basics by using Google.

One of these days I'm going to think of a really clever signature.

Hii frds I can't display all the components in the HTML form while working with COMMON.IO ,any solution !!! Wink | ;)

You need to provide a lot more information than this if you expect some useful answers.

Hi,
My name is Azeem and i'm a student of computer sciences.
i need help about my project.
i am developing an application using optical character recognition (OCR) for android system Mobiles.
i have some difficulty in choosing tools for this.
what are the best tool for developing Android application.?
i want to know is Java suitable for OCR or C# is best for OCR ?
Can we convert the java program is Android Application ?
or can we convert the C# program is Android Application ?

i am waiting for ur reply... Plz reply soon...

thank you .. Smile | :)

Why have you posted this here? You have already asked this in the C# forum, when it is a Mobile issue. Please post in one forum only as detailed in the Posting Guidelines[^].

Hi,
Friends suggest me how to read data bytes directly from Port rather than buffer. I want to do this because i want to calculate the time between each incoming byte from serial port.

Using Google will find lots of suggestions[^].

mahesh waghmale wrote:

Just to be clear...

In terms of a serial port it is always in fact buffered in some way by the hardware itself. It might not even be possible to read a single byte.

Following explains this well enough.

I have a problem with connected ireport with hibernate, I added all jars and all pojos and mapping files in the ireport classpath but always it appears for me an error in ireports :

entity class not found pojosmapping.Commande

here is a capture :
http://s12.postimage.org/96h6yplv1/image.png

the directory in which I point in ireport contains :

http://s11.postimage.org/40n1keymr/image.png

and the pojosmapping contains
http://s11.postimage.org/55h3psl3n/image.png[^]
and all this files are generated by netbeans IDE, I have never encoutered a problem like this there may be a bug in ireport 4.7.0 ?

do you have any idea

have you added the stuff also to the build?

There is a difference between the developing in the IDE (Netbeans/Eclipse) and running the program.
There might be some reference missing.

sorry I don't understand this sentence,
can you explain more

thanks

You have added all the hibernate stuff into your project - right?

So have you added it also to the Java build? the IDE will build the app each time you start it from your IDE or when you release the app. The hibernate bits&bytes need to be in that build too.

I don't know which kind of frameware you use and what you do there, but there must be a config file for the build. manifest file?Make sure the hibernate stuff is added there.

Hi Friends,
Please suggest me code in java which calculate CRC(16) in separate bytes i.e crc_hi and crc_low.

Thanks in advance.

A Google search[^] gives lots of suggestions.

Hi,

I have recently been asked to do some work with a Lucene installation. In short, I need to access the tokens that Lucene creates for a given document.

Does anyone know how I can get the tokens with Java?

Thanks in advance,
John.

Not off hand, but you could try here[^].

Thanks Richard.

I have spent quite a lot of time with Google searching for an answer - including the Apache site, but haven't found anything. Every example seems to be about how to get Lucene to index a document!

Did you read this[^]?

guys I need your help for source code Speech Recognition for greenfoot or java.

I need your answer soon..
thanks all

My answer is: Google.
Was that soon enough?
