JS limits?

[Evan]

im thinking about making a new project in JS, this application will need to write to a database. Can java do that?

Im not really sure what the limits of it are. Im not good with it.

[Evan]

The first thing I will want to do is find a complete java applet, and put it on the website to make sure i can get it to work.. and start playing and see if I can do stuff with java.

Can anyone point me somewhere that I could find a applet to do this?

[bsw2112]

this will be a good place to begin you research

http://java.sun.com/learning/tutorial/index.html

and yes JAVA can do all that stuff you need
but it won't be an applet...
it will be JSP (that is if you want this to be on the net)

Evan, you must be an idiot.

For the second time today:

JavaScript is in no way related to Java!!!

There is a seperate Java forum for questions like these. This forum is for questions about JavaScript.

And just to keep you from getting more confused:

JSP = Java Server Pages (Again not related to JavaScript)

[Evan]

eh. thanks for the help bsw2112

No, You are an idiot, very much so, because they are related - JavaScript uses the Java syntax for clientside scripting...

And I think he wanted it in JavaScript, and not any Server Side Language

It was the second time in the same day that I pointed out to Evan that JavaScript != Java.

But to educate you:

JavaScript gets its syntax from C++ (from C from BCPL yadda yadda). It was orignally called LiveScript when it was being developed.

Java gets its syntax from C++ (from yadda yadda).

Their syntaxes are similar because they come from the same place, not because one comes from the other. Netscape changed the name of LiveScript to capitalize on Java's recognition and purpose (write once, anywhere).

Netscape didn't change the name of LiveConnect though, and I don't know why.

Rarely is there the need to write to a DB with client-side scripting, so he either wants server-side JavaScript (not really worth it, IMO) or, as someone pointed out, a Java Applet (which could set up a connection back and do magic, yadda yadda).

I still think there are striking similarities... The String object for example... I'm not that much into C++ but I'm pretty far with Java right now...

[CornedBee]

The String object has been modeled in some places after Java's String class, but only in some. There's differences in the available methods, and after all, you don't have all that much choice.

Besides, PHP was modeled after Perl, yet there never are any postings in the wrong forum with that. Why's that?

The real problem are the similar names, which confuses people. But as Travis pointed out, we already told him once that day that JavaScript != Java.

Ohyes, very sure. And you don't have to capitalize Perl, it doesn't really stand for anything.

To add to the geaneology reports from earlier:

PHP gets its syntax from Perl. Perl gets its syntax from C.

It is safe to say that C is the mother of modern-day programing languages: C++ (not a language unto itself so much as a superset of C), C# (MS's .Net version of C++), VC++, Java, JavaScript, JScript (MS's extention to ECMAScript standards since they would be sued for admitting to extend JavaScript), J++ (don't ask me), Perl (written in C), PerlScript (the difference is very slight), and PHP. BCPL is the grandmother.

I don't know about Python and Ruby. I've not worked with them, but I'd guess they share the same syntax. I'm sure there are many others.

[bsw2112]

although javascript is mostly known for it's client side uses...
you can use javascript to access databse etc...
if you use it on the server (ie. server side javascript)

here is a very interesting link
http://resource.dcs.st-and.ac.uk/JavaScript/jsref/intro.htm

from that page


In contrast to pure client-side JavaScript scripts, JavaScript applications that use server-side JavaScript are compiled into bytecode executable files. These application executables are run in concert with a web server that contains the JavaScript runtime engine. For this reason, creating JavaScript applications is a two-stage process.


hhmmm....i wonder in what other language i saw that term used before ;)

Uhm... all of them? Duh.

And that isn't true, mind you, but it is very likely true. There are languages that aren't compiled into executables and just handled at run-time. Client-side JavaScript and Perl (though you can if you really want to you) are examples.

Point is, JavaScript nor Java have any distinction in being compiled.

http://www.pconline.com/~erc/perl.htm

Perl, the practical extraction and report language, has captured the hearts and minds of computer users everywhere. So much, so, in fact, that some people go so far as to write poetry in Perl, taking advantage of Perl's confusing syntax. (Perl is also called the pathologically eclectic rubbish lister.)

Notice they don't capitalize it, anyways.

True, True.. But after PHP it looks small being spelled at perl

[CornedBee]

But at least it DOES stand for something.

BCPL is the grandmother.

1) C++ is very much a language unto itself.
2) C# is MS's .Net version of Java, it's much more similar to that than to C++. (Yeah, I know about J#, but that one's a joke.)
3) J++ isn't really a language. Visual J++ was MS's IDE for Java, but they modified their own virtual machine so hard that it didn't work with normal Java anymore.
4) Then CPL would be the great-grandmother, and you forgot B ;)

I don't know about Python and Ruby.
Never heard of Ruby, but Python uses its very own syntax, which I find very weird, unreadable and dangerous, if intuitive. But to each his own. The typical sign of a C-like language is the braces for blocks:
{
code
}
Python uses only indentation, so
if cond
this is dependent
this too
this not
I think it's dangerous, because if I copy & paste this little snippet to my post again, but this time without the code tags
if cond
this is dependent
this too
this not
the program suddenly gets a different meaning. I don't think it's wise to trust functionality to something as volatile as whitespace.
But apparently people like it.

[bsw2112]

Uhm... all of them? Duh.


have you ever heard of rhetorical questions? ;)
you obviously missed something...

and to retort... no not all of them

there is difference between bytecode and machine code
only some languages use bytecode which renders a program platform independant(normaly slower) unlike C++ which, when compiled on a windows machine, will not run on unix....etc..

some languages that takes this approach are JAVA and Prolog to name a few.... I think .NET is also applying this process.

Maybe I could have java call a perl script in a hidden window that does the deed.

A hidden iframe, you can't hide windows.

You could also use remote XML loading, but that only works in Mozilla and newer version of IE, and in two different ways at that.

Again, not really. But we should ask Larry.


From Llama
It's actually a retronym, not an acronym. That is, Larry came up with the name first, and the expansion later. That's why "Perl" isn't in all caps.



2) C# is MS's .Net version of Java, it's much more similar to that than to C++.


Yeah, that is true. I didn't think about that at the time. This pushes C# down another step in the pedigree.


4) Then CPL would be the great-grandmother, and you forgot B ;)


I thought B was BCPL. And I didn't know CPL was a language or that it came before BCPL.

So: CPL -> BCPL -> B -> C -> C++ ....?

I don't think it's wise to trust functionality to something as volatile as whitespace.


I agree completely. Why I think VB is a bad language for serious programmers to learn on.


there is difference between bytecode and machine code

True, and sorry to not point out the difference. Java and JavaScript do have the distinction in wanting to almost compile for the sake of cross-platform useability. But they want to be cross-platform for different reasons. Still, the only relation between JavaScript and Java is Netscape wanted to ride on the buzz around Java so they renamed LiveScript before its release.

And... Funny Dave.

[CornedBee]

So: CPL -> BCPL -> B -> C -> C++ ....?

Yeah. I read the whole history of C++ not long ago, but the site is now down.

CPL was a kind of theoretical programming language, much too complicated for practical use. It was simplified to BCPL (Basic CPL), but that was still not enough, so it was simplified again to B. B was written for a special platform though, so C was created from it. And C++ is C with several modern programming features.

AH returnes, that is a different story.

I completely argee with you on this one, I dont like that about VB either.

Thats one cool thing about perl

if( $this == 1 || $that == 2) {
#do this;
} else { #do something ;}

[Travis G]

Originally posted by Evan

There are many cool things about Perl. The syntax however is common to the lineage, so it is the same for JavaScript and Java (with the exception that scalars and comments are denoted differently).

There is also the neatness of short-circuiting in that example you give. If $that is truly '2', then the program will not bother checking the value of $this (I think short-circuiting runs right to left, but I could be wrong).

Short-circuiting is not unique to Perl, it is just annoyingly absent in VB.

This thread definately belongs in Chit Chat now.

[CornedBee]

Short-circuting runs left-to-right, as the && and || operators are evaluated.

www.sun.com =) - I'm learning Java as well, but I gotta warn you, converting isn't that easy - there's a dev SDK for J2ME using MIDP so developing and debugging on the computer is easy. I'd suggest you learn basic Java before trying J2ME - and if you need an IDE, I suggest you use Eclipse(developed by IBM, IN Java) It's really good - I've come to like it more than the VB6 IDE =).

Cheers!

What is this magical 'Copy & Paste' of which you are speaking ? :p

[CornedBee]

J2ME and J2SE have quite different APIs, especially for drawing. You might be able to write some tiny wrapper classes though, I did that for my Tetris, which was never finished.

B was before C, read my post again.


And by now we're again off-topic, because this thread started about JavaScript and is now about Java again.

[Evan]

why are J2ME and J2SE so differently made.
I dont see the point

[CornedBee]

The point is that PCs and tiny devices have very different capabilities and need different frameworks to support. Another point is that they have different purposes too, and a program written for the PC is unlikely to run on a microdevice, while a program written for a MD is unlikely to be useful on a PC for lack of functionality.

The kept what they could, e.g. the classes frrom java.util that exist in ME are the same as in SE.

But there are no float and double datatypes in ME, just as an example.

The processor in micro devices are not as large as the ones in your desktop PC, so even down to the 'ASM' plane it has to be different.
