I know ZIP about Java. Where Do I Learn?

I know virtually nothing about Java. I have avoided it but now I want to learn and so far everything I have seen is pretty much Greek. I have used FP2003 and Dreamweaver to build web pages but not delved ino the guts of Java. Where do I begin?

URGENT !!!! I know nothing about java .... ;o)

Hi all,
here is my problem, I am working on a demo for a customer, I am business consultant and I know nothing about java and I have noone next to give a hand, so please help.
I integrated a content in a Learning Management System. When launching this content in the LMS, an applet is created. I get a first page where I have to chose an option. When clicking on any of the options, I get nothing. On my java console, I can read this :
java.lang.NoSuchMethodError: javax.swing.UIManager.c()Ljava/lang/String;
     at com.cbt.jasmine.Jasmine.Jasmine.b([DashoPro-V1.32-013000])
     at com.cbt.jasmine.Jasmine.JasmineApplet.run([DashoPro-V1.32-013000])
     at java.lang.Thread.run(Unknown Source)
What can I do to make this ******* content work.
Many thanks for your answers.
XToff.

First of all, nothing is urgent to us, only to you.
Second, the error is clearly stated being NoSuchMethodError i.e. the program is trying to call a method that hasn't been for some reason included in the program.
Third, I have no idea what Learning Management System is (and I'm not the only one).
Fourth, why did you put "Re: URGENT !!!! I know nothing about java .... ;o)" as the topic instead of "Learning Management System"?

hi

Any body know of a Java Script for retrieving learner location from LMS; similar to name?

Looking for a script to pull learning location from LMS. Then based on location send them to a particular slide. Any help would be appreciated.
Example: learning from Chicago gets slide 2. LA slide 3, and so fourth...

Are you using Captivate 8, so that you have access to the system variable cpInfoGeoLocation? And are your users on a device that has detection of location activated?
For the JS you'll have to wait for someone else, but I think this information is necessary. And since you don't want to try advanced/shared actions...just wait.

NO clue about JAVA but need help please

I am cleaning up someone's else work who used to be employed here. I know ZIP about Java but am becoming more and more familiar with WAR files and deplying them with Jrun on an NT2K Server.So here is what I have. I have a deployed app from months ago. I have a new app to deploy. I did this successfully. I can access it, etc. But I am getting some SQL error.
Can anyone give me any idea what it could be? I have looked at my sqlcustomauthentication.java file and i have not anything to it. Why would something change on this when all I really did was re-deploy it.
Here is the error.
Thanks a TON!!
java.lang.NullPointerException:

It looks like maybe you are having a problem in the way you are accessing the authentication on your db. From the error message, I would say the name field needed to log in is never being set

Questions about Java Servlets and JSP

Hi,
I'm a confident Java Programmer (and really enjoy using this language) but am very new to Java servlets and Java Server Pages.
I have previously worked with Perl on my web projects (simple 'league' style voting pages). I read in my 'Core Java' book that I should no longer use perl or even cgi.
I need to know more about Java servlets and Java Server Pages so I can make the switch to a 'real' programming language.
I have a few questions:
How should I start to learn JS and JSP?
How applicable will the java knowlegdge I have already be?
Are JSP common on the world wide web?
What tools do I need to start? (I currently develop in JBuilder and have Java 1.4.1 Standard Edition)
Is it likey my web host (and others) will support JSP?
Thank-you very much for helping a novice get started,
Regards,
Paul

Hi, Steve ...has to be frustrating! But do not despair.
Let's suppose the servlet it's named MyServlet on package org.servlets
WEB-INF should look:
WEB-INF
classes
org
servlets
MyServlet.class
web.xml
web.xml file should have this two declarations:
<web-app>
<servlet>
 <servlet-name>MyServlet</servlet-name>
 <servlet-class>org.servlets.MyServlet</servlet-class>
</servlet>

<servlet-mapping>
 <servlet-name>MyServlet</servlet-name>
 <url-pattern>/MyServlet</url-pattern>
</servlet-mapping>

</web-app>Now, once the container starts (Tomcat?), you should be able to see that servlet in:
http://localhost:8080/[my-context/]MyServletAnd what my-context is? The web application context. This string should be empty if your're deploying to the root context, otherwise should the context name. In Tomcat, deploying to root context defaults to using webapps/ROOT.
Sorry for my English, but I felt the need to answer your request. I hope it helps despite my writing.

How To Ask Questions The Smart Way
Eric Steven Raymond
Rick Moen
Write in clear, grammatical, correctly-spelled language
We've found by experience that people who are careless and sloppy writers are usually also careless and sloppy at thinking and coding (often enough to bet on, anyway). Answering questions for careless and sloppy thinkers is not rewarding; we'd rather spend our time elsewhere.
So expressing your question clearly and well is important. If you can't be bothered to do that, we can't be bothered to pay attention. Spend the extra effort to polish your language. It doesn't have to be stiff or formal - in fact, hacker culture values informal, slangy and humorous language used with precision. But it has to be precise; there has to be some indication that you're thinking and paying attention.
Spell, punctuate, and capitalize correctly. Don't confuse "its" with "it's", "loose" with "lose", or "discrete" with "discreet". Don't TYPE IN ALL CAPS; this is read as shouting and considered rude. (All-smalls is only slightly less annoying, as it's difficult to read. Alan Cox can get away with it, but you can't.)
More generally, if you write like a semi-literate b o o b you will very likely be ignored. So don't use instant-messaging shortcuts. Spelling "you" as "u" makes you look like a semi-literate b o o b to save two entire keystrokes.

I've written a replacement zip file creator class. Not much tested but it seems to work, however I've yet to try it with the version of WINZIP that rejected my previous attempts. Oh, and the stored dates are garbage.

How to create password protected zip in java?

I want to create a password protected zip file in java...java.util.zip does not support this...how to do this???
Someone please help...

Thanks for Reply"[email protected]"
Till today whatever i got is this------
In java there is no way to make a password protected zip...java.util.zip package does not support this thing...
To do this we require Third party API---
Two third party Api i got...
one is "CHILKAT API for java"
and another one is "IPWORKS"http://www.componentsource.com/products/ipworks-zip-java-desktop/index.html
but both of these API are paid...
Even this problem has been reportd as bug in the bug database....
And the other way is related with Class Process Builder of java...
If someone knows more about this then tell me...

Question about Java apps structure

Hello guys,
I'm a professional C++ programmer and I would like to start learning Java. I'm reading about Java from here and there and would like to ask you about how a java program is structured compared to C++.
So in C++, I have main.cpp (or any other file name, doesn't matter), which contains a the main() function, and I have .h and .cpp class files that I instantiate (basically) in my main function to get my program to work.
In Java, I'm confused and can't really find the "general" rule to how stuff are organised. I noticed that every class has a main function (why?), and there's no global scope. And "somehow", file names must exactly be equal to the class names.
The question is: how are Java files of classes (and other stuff, if available) are arranged to create a program? What's the standard why? And How can I have many classes together in a single main()?
Thank you for any efforts :-)

Thank you guys for the replies. I still have some more doubts :-)
Do I have to have a file for the implementation and a file for the definitons, like cpp and header files? or just everything inside the class?
Why does Netbeans fail to compile when I change the class name? what should I change with the class name in general to have it compile correctly? From what I understand till now, the top level class's name (the class with the main() function that's gonna be executed) has to be equal to the file name (and I got that this is the sufficient condition for the app to compile), while the same file can have more classes if I wish. Did I get that right?
I don't know if I get that right too, we pass only a SINGLE class/file to the compiler, and it automatically resolves ALLLL the included files automatically, unlike C++, where all cpp files have to be passed to the compiler/makefile to create object files, and then the executable is created after linking all those object files with the libraries together. i.e.: Java doesn't really need a makefile because making is really simple with only 1 filename. True?

Some questions about Java deployment steps and techniques

All my java experience is coding and testing in my local machine (where, of course, a jre is available), but ... when I deploy to other people, they may not have a jre or they may have a different version of it than the one needed to run my application. I've read different stuff online including jars and java web start but still I have many questions.
(1) first one first, Sun contradicts common sense, when it says that i can redistribute my own customized light version of their jre by taking out some files (java.sun.com/j2se/1.5.0/jre/README). there are two ways for me to get a jre: Way one is by downloading one from Sun, the download comes as an *.exe file and I don't see how I can take files out of it, so do you know how?. Way two would be by simply copying the set of files i choose (according to that Readme) from my current jre installation (the one on my \java\jdk\jre directory), does this make sense?, (if you're under windows) doesn't an installed version of a jre need a couple of dlls plus some new registry entries?, this contradicts common sense, if I'm not wrong, that Readme is a nonsense, but since that readme is at each of us jre installation \java\jdk1.x\jre\Readme, it can't be a nonsense, therefore I'm wrong, therefore the answer is either Way 1 or Way 2, HOW? ... or maybe there's a Way 3?
(2) Say I never read that Readme so I download the jre (as an exe) to bundle it along with my application in a jar ... now I'll give my neighbor either a jar with two exes or two exes jars ... is there a way to make a jar so that two files get executed? ... if the answer is No and I have competition from a second neighbor, then I believe I'm asking my first neighbor to choose my application based on our friendship, that's not reasonable if we are doing business, so Java loses.
(3) Say that my application is a single executable file like this,
class X{
public static void main(String[]$$$){
System.out.println("Console, where are you?");
At this point, say that my neighbor accepted the two executables, he executed the jre.exe and has jre6 in his system, now he double clicks on my X.jar ... it's a console application and jar files are not associated with the java.exe launcher since java 5, but with javaw which doesn't open any console ... how do i make it so a console opens and prints "Console, where are you?" ... do I ask my neighbor-customer to add a couple of lines to his path and open his console and (please) enter java -jar jarfile.jar? ... isn't it too much? ... i hope i'm wrong cause this is kind of discouraging
(4) I've read that by installing a more recent version of a jre on a system that has an older jre (there to help other applications work), I might be causing a problem for the other applications to run ... I guess that's the reason why that Readme kind of encourage to redistribute a "private" version of a jre (one that doesn't come with a java.exe launcher ... any feedback on this?
(5) I'm reading a lot of hype about Java Web Start ... it looks better than the traditional jar/jre deployment ... but setting up a MIME type to *.jnlp, it doesn't come with some free hosting I've checked ... somebody can recommend a free hosting service that allows to set a *.jnlp MIME? (I'll appreciate a suggestion here, cause I would like to test Web Start)... and, anyhow, how you people compare it with the paradigm of the single executable file?.
Thanks. Your feedback is highly appreciated.

...it looks better than the traditional jar/jre deployment ... but setting up a MIME type to .jnlp, it doesn't come with some free hosting I've checked ... OK. You cannot define new mime types, but perhaps the site already has it defined. An easy way to check is to upload 'any old file' that ends in .jnlp and use the [mime type checker|http://pscode.org/mime/] to see what content type it is served as.
..somebody can recommend a free hosting service that allows to set a .jnlp MIME? (I'll appreciate a suggestion here, cause I would like to test Web Start)... I'm pretty sure the Google based sites offer it.

I am working on my Final year Project about java program plagiarism.
i.e. My system finds similarity between two programs by "Source code" to check whether there are plagiarism.
And now i need plenty of samples and need your help.
I need two types of sample:
1. original version - a version written by your own.
2. plagiarized version - a version which is copied from original version and has modified to conceal that it is a plagiarism.(Try to treat the teacher)
My two sample programs are:
1. Find shortest path by Dijkstra's algorithm.
2. Find the determinant of a N x N matrix.
Both programs read data from txt file as input.
Now, I sincerely invite you to help me to make samples
You can choose to do the version(original or plagiarized) and the program you like.
After you have finished, please kindly send to [email protected]
If you decide to do plagiarized version, please download the following sources and modified them.

Thank you very much. Looking forwards to your program.

Ha ha, good try.
You know, if you had posted whatever you have achieved so far, you might actually have got the help you so obviously need. But now your only chance of getting any help here is to get yourself another username.
If this were true, your professors would have gladly supplied you with research material in exchange for use of your "system".

Need to find a book about Java history

Hello,
I'm not sure I am posting in the right forum, but anyway...
I am currently performing a research entitled "The use of the Java platform in the entertainment industry". To begin, I need a book where I could find hitorical information about Java cretion and evolution, but I can't manage to find one. The history given on the java.sun.com website is way too short and all the books I could find deal with technical aspect of Java...
Does anyone knows a book that could interest me?

Thanks for the links, but as it is an academic
dissertation, I'd rather find a book... The Internet
is still not really trusted as an academic source of
information.
So there's no chance for me to find a book with a
proper history (better than the half page introduction
in present in every Java programming book)Well then why not try journals? You won't find one book from which you can write your whole thesis, and if you did, you probably wouldn't get very good marks. As a guide, my MSc dissertation had around 300 references and 60k words, which is not uncommon. Journal articles are far more targetted, and certainly more likely to cover such a specific area as what you are asking of.

I have a macbook pro running 10.8.5. I know little about computers but have started my computer in safe boot as this is the only way I can connect to Safari.

I am currently in safeboot as Safari will not open otherwise. my emails are working fine. I do not know much about computers but looked at a couple of previous discussions and have pasted the results of an Etrecheck - please can you tell me why Safari isnt running like usual! my daughter likes using my computer for games but she has another user id. I would be grateful for help. Also is Safeboot ok to use?

Yes, it will do no harm, but it is meant for trouble shooting and you should not have to use it all the time.
