Beginner programming questions

Okay so I am looking at learning a programming language using VS express but I have a few questions first.
What language would you recommend that will teach me about the inner workings of a computer, such as memory management etc.
What tips would you give for tidy code? I hate my work to be messy.
If I ever became decent at the language, would it ever be worth getting a MS qualification for development?
I apologize if I have posted this in the wrong section, I am new to these forums
Thanks in advance
First, I recommend that you consider getting the FREE Visual Studio 2013 Community edition so you will have access to a complete tool set:
https://www.visualstudio.com/downloads/download-visual-studio-vs
If you really want to learn "about the inner workings of a computer, such as memory management etc.", you can learn C++. However, as most modern languages use a managed environment, and C++ has a very steep learning curve,
I suggest you start with C# (syntactically similar to C++), then investigate C++ later.
As far as "What tips would you give for tidy code? I hate my work to be messy." is concerned, let Visual Studio format your code and make it readable automatically. If, after some experience, you don't like default formatting, you can use
VS Tools->Options to change it to your liking.
For getting in the door to a good job, Microsoft certifications, like degrees, will help you open the door. Staying inside will depend on your skills and productivity.

Beginner font questions

These are some beginner font questions if someone has the time/patience.
I've never paid much attention to fonts over the years, never installed
any other than those that might have come with applications. Early on,
15 years ago or so, I settled on Palatino and I've stayed with it for
most docs (Word 5.1a and now Word vX) and often for other apps (Safari,
Now).
I just upgraded to Tiger (10.4.4) and I use Word vX.
Questions:
1. I gather from looking at Font Book that when I'm using Palatino in
Tiger that OS X is getting it from my OS 9 System folder for Classic.
It does not look like Palatino is in any other locations including MS
Office vX. Does that make sense?
2. I always thought that Palatino was a very basic, always available
font. Not so?
3. If I decide to stop using Classic, and I'm close to that time, can I
transfer those fonts to OS X? If so, to which location is best.
4. And are the same fonts used for printing and screen? In other words
back in pre OS X days I thought some fonts came in screen versions and
print versions but my memory is hazy on that. Not only that.
Thank you for any education or links for info.
Powerbook G4 Ti Mac OS X (10.4.4)

1. I gather from looking at Font Book that when I'm
using Palatino in

That's correct.
2. I always thought that Palatino was a very basic,

font. Not so?
It seems to be out of favor.
3. If I decide to stop using Classic, and I'm close
to that time, can I
transfer those fonts to OS X? If so, to which
location is best.
Yes, you can just put it in Users/username/Library/Fonts (or Library/Fonts for all users).

I have a programming question

Hi
I have a programming question here. I spent a lot of time doing it, but I still can't get it. Here is the question :
Write a method called countTo that takes one integer as a parameter and prints a
comma-separated list of the numbers from 1 to the value of the parameter, or an
appropriate error message if the parameter is less than one. In either case (if a list
of numbers is printed, or an error message is printed), after printing, the cursor
should be advanced to the next line.
For example, if the parameter has a value of 1, the method should just print the
the value 1 to the screen followed by a new-line character. If parameter has a value
of 5, the method should print the following (exactly as shown, make sure there is
no comma after the last value, and that all values are on one line with no spaces
between them):
1,2,3,4,5
This method should only print to the screen, and should not return a value.

I have a programming question here. I spent a lot of
time doing it, but I still can't get it. Please post what you have done so far.

Misc Basic PL/SQL Application Design/Programming Questions 101 (101.1)

---****** background for all these questions is at bottom of this post:
Question 1:
I read a little on the in and out parameters and that IN is "by reference" and OUT and IN-OUT are by value. To me "by reference" means "pointer" as in C programming. So it seems to me that I could call a function with an IN parameter and NOT put it on the right side of an assignment statement. In other words, I'm calling my function
get_something(IN p_test1 varchar2) return varchar2;
from SP1 which has a variable named V_TEST1.
So.... can I do this? (method A):
get_something(V_TEST1);
or do I have to do this (method B):
V_TEST1 := get_something(V_TEST1);
Also, although this may muddy the thread (we'll see), it seems to me that IN, since its by reference, will always be more efficient. I will have many concurrent users using this program: should this affect my thinking on the above question?
-- ******* background *******
So Far:<< I've read and am reading all over the net, read and reading oracle books from oracle (have a full safari account), reading Feurstein's tome, have read the faq's here.
Situation Bottom Line:<< Have an enormous amount to do in a very little time. Lots riding on this. Any and all pointers will be appreciated. After we get to some undetermined point I can re-do this venture as a pl/sql faq and submit it for posting (y'alls call). Some questions may be hare brained just because I'm freaking out a little bit.
Situation (Long Version):<< Writing a pl/sql backend to MS Reporting Services front end. Just started doing pl/sql about 2 months ago. Took me forever to find out about ref-cursor as the pipe between oracle and all client applications. I have now created a package. I've been programming for 20 years in many languages, but brand new to pl/sql. However, pl/sql sql has freed me from myriad of limitations in MS RS's. My program is starting to get big (for me -- I do a lot in a little) pks is currently 900 lines with 15 functions so far. Currently SP (pls) is back up to 800 lines. I get stuff working in the sp then turn it into a function and move it to the package.
What does application do?:<<<< Back End for MS Reporting Services Web front end. It will be a very controlled "ad-hoc" (or the illusion of ad-hoc) web interface. All sql queries are built at run-time and executed via "open ref cusor for -- sql statement -- end;" data returned via OUT ref_cursor. Goal is to have almost 100% of functionality in a package. Calling SP will be minimalist. Reporting Services calls the SP, passes X number of parameters, and gets the ref_cursor back.
Oracle Version: 10.2 (moving to 11g in the next 3 months).Environment: Huge DW in a massively shared environment. Everything is locked down and requires a formal request. I had to have my authenticated for a couple dbms system packages just to starting simple pl/sql programs.

So it seems to me that I could call a function with an IN parameter and NOT put it on the right side of an assignment statement. The IN parameter is not passing by reference. It is passing by value. This means variable/value of the caller used as parameter, is copied to the (pushed) stack of code unit called.
An OUT parameter means that the value is copied from the called unit's stack to the caller (and the current value of the caller's variable is overwritten).
To pass by reference, the NOCOPY clause need to be used. Note that is not an explicit compile instruction. The PL/SQL engine could very well decide to pass by value and not reference instead (depending on the data type used).
Note that the ref cursor data type and the LOB data types are already pointers. In which case these are not passed reference as they are already references.
The NOCOPY clause only make sense for large varchar2 variables (these can be up to 32KB in PL/SQL) and for collection/array data type variables.
As for optimising PL/SQL code - there are a number of approaches (and not just passing by reference). Deterministic functions can be defined. PL/SQL code can be written (as pipelined tables) to run in parallel using the default Oracle Parallel Query feature. PL/SQL can be manually parallelised. Context switches to the SQL engine can be minimised using bulk processing. Etc.
Much of the performance will however come down to 2 basic issues. How well the data structures being processed are designed. How well the code itself is modularised and written.

XML BURSTING PROGRAM QUESTION

Hello All,
I have customized an oracle application program with xml publisher.The program prints the report in PDF format.
My questions is where this output copied in the server .I am not able to find the pdf report in $APPLCSF/out/.
Do i need to use XML bursting program to achieve this?If yes i am new to xml coding can anyone help in creating busting control file.
My object is to print the pdf report to unix server directory
THanks

Pl post details of OS, database and EBS versions.

Calendar Program Question

Hello! Among the lab assignments I have done for my class, I have this calendar project I've been working on for a good while now. My only question is how do I set the days of the month properly with the empty columns I have encoded in the program? This is a long program and I really haven't put any time into making it look neat, so bare with me!
What I get so far in the interaction pane is:
March 2008
              1 2 3
4 5 6 7 8 9 10
11 12 13 14 15 16 17
18 19 20 21 22 23 24
25 26 27 28 29 30 31
and what I'm looking for, obviously, is:
March 2008
                    1
2 3 4 5 6 7 8
9 10 11 12 13 14 15
16 17 18 19 20 21 22
23 24 25 26 27 28 29
30 31> Sometimes I over look something minor, but I'm stumped and this is the ONLY thing I have to do to finish this project!

Well, I could move the displayStr = monthStr into the other section of the code where the months are at, but as far as using java.util.Calendar/GregorianCalendar classes the professor made no recommendation of it (though it would be easier no doubt.) That's what he told us to use to display the month properly. I did look in the web for other examples and they did use the java.util.Calendar/GregorianCalendar classes, but I have no idea how to properly implement it. Besides, I was not asking about redundancy.
After I made the thread, I did work on it a little bit more, and I changed:
   if ((lastTwoYear >= 0) && (lastTwoYear <= 99))
     dayofWeek = lastTwoYear * (1/4); into:
if ((lastTwoYear >= 00) && (lastTwoYear <= 99))
     dayofWeek = (int) (lastTwoYear * .25);The year 2008 was properly displaying everything on the correct dates, but the other years are off by a few days. So now its either the computation in the long sequence of dayofWeek variable, or (what the professor mentioned in the assignment) it could be:
     loop (for the number of days in the month)
       displayStr = displayStr + <digit in field width of 3>
       if last digit in row, then append �\n� to displayStr}The whole loop, including the "append "\n" to displayStr" doesn't make much sense. So that could be where I'm having problems.

Please answer a programming question for an admin

I'm not a programmer (although my interest is growing), so I can't answer this question in a discussion regarding how Win32API w/OLE and COM is SO much better than programming for Unix/OS X applications.
The original discussion was in regards to OS X's superior Unix based security, he devolved to this. Having only begun my venture into programming, his questions are a little above my head at this point. I'm also interested (as an amature programmer), how this would be accomplished in OS X/Unix.
Thanks in advance.
Here's his position:
*(1st entry)*
I have unsed Windows and many flavors of Unix and I have written programs in Assembler, Fortran, Pascal, Cobol, RPG, Smalltak, Basic, PowerBuilder, Delphi, C, C++, C#, Java, and Perl, and I have been programming for over 20 years, so I do have extensive knowledge about programming.
So I have one question for you:
If you had to build a business application that has to allow users to, spell and grammer check, and perform financial calculations, and render the HTML, how would you compare the effort to do this in Windows versus that in Linux, AIX, Solaris or any other Unix operating system?
I can make this business application have these features in ONE DAY on Windows, because COM and OLE lets me, use Word to spell and grammer check, Excel to do the financial calculations, and IE to render the HTML!
I make my living building complex customized business software, and Windows allow me to build these applications by myself in weeks, when it would take me and a team of programmers months to do these same things in Unix because of the lack of an the Win32 API, COM, and OLE, or I would have to BUY third party libraries that did these things, and deal with the licensing, versioning, and vendor problems that go with them, and none of those third party librabries would be close to Word, Excel, and IE in CAPABILITY!
HONESTLY tell me and others reading this thread how you would go about create the customized business application I described above by yourself in a Unix instead of Windows, and tell us how many MONTHS or YEARS it would take you, or how you would have to BUY some other third party libraries to do what Word, Excel, and IE!
Anyone who thinks a Unix has more CAPABILITIES than Windows, has never used Win32API/COM/OLE/.Net, and does not build customized complex business software for a living, because we people that do are the reason that you find some much customized business desktop software for Windows, and so little for any Unix.
I have nothing against Unix, and it is great for simple business tasked server software, but for complex business tasked desktop software Windows with Win32API/COM/OLE/.Net wins hands down!
*(2nd Entry)*
A System administrators view of an operating system and an application developers view are entirely different, and the Win32API/COM/OLE/.NET simply make my job so much easier, and you simply don't understand because you do not have to deal with the "dirty' details of making what a user wants, which is why your definition of "integration" and mines are totally different!
With the spell check you talked about, how will you keep in in synch with the dictionary in Word where the user is constantly adding and removing words?
No, you would have the user to have to maintain two different spell check dictionaries, and you would totally ignore the grammer check requirement!
Cutting and pasting data between applications is simple integration, and not the complex type that I am talking about.
Can you make your application display and use the MacGourmet menus appear in its own window, and to access and use the MacGourmet functionality (ie. search for a recipe) in its own window?
Give me one example of a Unix application that can display the menus of another application, yet alone control its features!
Of course you can't, because you need COM and OLE!
I am quite familiar with different flavors of Unix, but those operating systems do not have the rich API and program integration features namely COM and OLE that Windows has, because it violates the Unix idea of security by process isolation!
Yes that idea of process isolation keeps the operating system safe from malicious code in applications and from one application taking the others down, but you lose the power of programs working together, and you simply cannot build the type of customized business applications that I build by myself, without reinventing the wheel over and over and without having a large team with lots of programmers.
For example, my customers and millions of others spend all day working in Word and Excel, and the Windows idea that I can transparently integrate my complex business applications right in Word and Excel menu, and into their templates and macros, is why third party developers like me prefer Windows over Unix, regardless of how much better security in Unix is.
Do not get me wrong, Java improves business application development on Unix, but unfortuantely it is not feasable to rewrite ever legacy application in Java, and Java does not integrate well with other programming languages.
I used to code business application for both IBM MVS and Sun Solaris, and I never want to go back to those "bad" old days again, once I took the time to learn how to PROPERLY code using Win32API/COM/OLE/.NET!

At risk of feeding the troll I'll wander in here:
NOTE: Since this is an Apple programming boards and I have limited experience programming on traditional Unix systems (and most of that in college) I will confine my answers to the area I know.
If you had to build a business application that has to allow users to, spell and grammer check, and perform financial calculations, and render the HTML, how would you compare the effort to do this in Windows versus that in Linux, AIX, Solaris or any other Unix operating system?
I can make this business application have these features in ONE DAY on Windows, because COM and OLE lets me, use Word to spell and grammer check, Excel to do the financial calculations, and IE to render the HTML!
Note that this scenario assumes the user has Microsoft office installed. The person argues that they don't have to purchase libraries to program but what they are effectively doing is simply transferring that cost to user. I don't have to purchase libraries but everyone of my users needs to. Good for you, very good for Microsoft but bad for your customer - IMHO. OK, I know "But all Windows business users have Office installed already." When it comes free with the system then I'll retract my objection.
Under OS X and Cocoa many of these functions are intrinsic to the system layer and do not require any applications to be installed. Using Cocoa you can write a simple Word processor that has rulers, full font manipulation (including kerning, spacing and leading), Document Save and Load, Printing, Export to PDF as well as spell-checking in under 10 lines of actual code. Adding a custom file type and icon for full system integration will add another 5 minutes to your programing.
In case you think I'm blowing smoke here is a tutorial from 2002 (yes, this has been possible for over 5 years) outlining the 8 line Word Processor build in Cocoa. http://www.stone.com/TheCocoa_Files/What_s_sofunny.html
And yes, Cocoa also includes Webkit so I can add full HTML rendering by dragging in a WebKit window to my user interface. For an experienced Cocoa programmer this certainly sounds like less than a day of programming - in fact it sounds like a good tutorial for a middle-experienced training day or 2 day class in Cocoa.
I won't include the link to the 1 line web browser you can build in Cocoa using Webkit because it's shorter than the description. Feel free to search for it if you want to.
HONESTLY tell me and others reading this thread how you would go about create the customized business application I described above by yourself in a Unix instead of Windows, and tell us how many MONTHS or YEARS it would take you, or how you would have to BUY some other third party libraries to do what Word, Excel, and IE!
BUT this is all done from the stock system that is on every OS X computer not simply those with Office installed. Obviously you'd need to add some features that were more complicated than this - because any halfway decent programmer could turn this stuff out - and polish takes a while but to meet the requirements of the challenge it would take 2 days tops.
Is every *nix programming environment like this? I don't know I can only answer for the system that I have experience with and is the concern of this board. If you really have questions regarding *nix programming then I suggest you find an appropriate board and troll^H^H^H^H^H ask there.
If you're ever serious about programming on the Mac feel free to stop by and actually take a look at it. I think you'll be surprised.

Is Flash Builder a good beginner program for creation of android app?

Hi there,
I'm planning to create a Android app and I'm searching for the right program to do so. I have absolutly no knowledge about programming, but happen to have Flash Builder as part of the Creative Suite CS6. As I need to learn everything from the complete beginning, I'd like to pick the best program for this purpose, so I don't learn a lot of stuff not be able to achieve the product I'd like. Let me give you a example of what I will try to achieve:
Program for Android:
- first page of the program would be a welcome page, it would be nice to be able to put a login and password option here, but that is not neceserry.
- second page would be a list of 14 options - books - and by clicking on each option I would open a little book (cca 30 pages).
- this option would be nice: let's say I open the third book and stop reading on page 10 and stop/close the program - the next time I open the program it would open the program on that very 10th page of the third book
- this option would aslo be nice: some kind of searching modul to search keywords in the book.
Is this kind of app possible to make in Adobe Flash Builder, or would it be better to learn another program? Thanks a lot for your experiences! Hedvertel

If you have a licence for Master Collection you should have the info about what it contains.
A few moments on Google took me here: http://www.ecostsoftware.com/adobe/adobe-creative-suite-cs6-master-collection-mac_p5565?gc lid=CNzN5MbKmLoCFXDJtAodWDoA3w
The included software is listed. I don't think Muse existed when CS6 was originally released.
I didn't properly read George's answer, but I don't see Muse as a great app builder.
I kind of don't understand at all, why you even answer, if the only thing you are saying in this disucssion is that it's too ambitious and that I'm stupid even asking.
Saying the project is overly-ambitious is a great answer to your question. In post 5 you clearly valued that answer enough as to be giving up on the project.
I didn't say you were stupid asking these questions, it's more a case of asking questions you should be able to answer yourself without too much trouble.
I still think that with your current level of understanding, takling this project with no experience of any programming or web technology is overly ambitious. Start small and build on that.
You don't say why you want to do this particular project - whether it's about learning in general or that project in particular. If it's learning in general there's nothing to stop you - there are a ton of tutorials out there. If it's for this particular project only, I would stop now.
You need to invest a significant amount of time to learn this stuff.
Are you on some design course? Why do you have the master collection?

Apple iPod Nano replacement program - question

Hello, Apple community,
I have a question about the new replacement program of the iPod nano 1st gen.
The program doesn't state whether or not you get a refund or a new iPod nano (the small squared once with touch screen).
The program says that you'll get a replacement iPod Nano, but isn't very specific if it is the new generation.
I apologise for any spelling mistakes and such.
Thank you for any answer,

Hi lindsayfromspencerport,
I can say it is not a scam - Apple is definitely replacing the iPods. Once I read the article and went to apple.com, that proved it. Apple.com would never risk another class action lawsuit over this iPod.
My First Generation iPod was given to me at work for being the winner of a give-away drawing and about a year or so ago it overheated and erased all the info on the iPod. Now it will only charge and drain the battery. It no longer allows me to store any thing on it.
I am glad that Apple is doing this exchange. I thought I was just out of luck and was glad I had not paid full price for it. I love my Nano and used it constantly!!!
Just send your's in using the box and label they send you and give them 6 weeks like the apple.com website says, Apple will make good on their product. Millions of people don't stand in line and wait weeks/months for their new products to arrive for no reason, trust me. Oh, by the way, I know this for sure.....I work for a wireless phone service that has been dealing with Apple for Yearsssssssssssss.....and every year the same thing. People will give anything to get a product with that apple on it.

Beginner Java questions

Hello:
I'm looking for some guidance on a few things I am confused on. Can somebody tell me or point me in the right direction on how you would write and equivalent compound statement for
x = 2 * x;
sum = sum + num;
y = y / (x +5);
lastly
What type of input would I use for :
import java.util.*;
public class Strange
static Scanner console = new Scanner (System.in);
public static void main (String[ ] arg)
int x;
int y;
String name:
x = console.nextInt ();
name = console.nextLine ();
y = console.nextInt ();
I appreciate any guidance and help provided on this. I'm struggling to wrap my head around some of these things.

For the first question, I would suggest reviewing this section and the following ones of the Java Tutorials:

I don't understand what the second question is asking for.In reply #2 the OP tried to clarify the second question:
Well, I'm tasked wtith stating "what type of input the progragms requires and in what order the input must be provided" for the program I stated. >Beyond that, I'm not sure either and that's why I'm looking for help. "Looking for help", eh?

Java Programming Question

Hi,Everybody:
I have a question about Java programming. If I want to write a java class code called if.java like below, how should I do to make it pass the java compiler and make it work. I know the words "if" and "for" are reserved words. I just try to figure it out that is it possible??? Do I need to create my own java compiler or recompiler?
public class if
public if() { }
public static for test()
return new for();
public class for
public for() { System.out.println("for class constructor"); }
}

I don't think you can bypass the compiler's rejection of this. There is little point to naming the classes after keywords. Not sure if it's case sensitive though, so maybe "If" or "For"? Otherwise, try "if_" or "for_"

Audio Programming Questions...

Hi everyone,
I am very new with audio programming with Java and I have a couple of questions...
(1) How can I specify a Line from which I can capture audio signal. I want to capture signal from a MICROPHONE and then process the signal (with a FFT function). I tried to use Port (instead of DataLine) and I managed to get the specific port (Port.MICROPHONE) but it seems that port has no function to read from the line. Therefore I assumed that the only way to capture and process audio signal is through DataLine. However I cannot specify the line. How can I do that???
(2) Is it possible to capture and process audio signal through Port??? I mean can I read bytes from a audio stream and write it to a TargetDataLine???

Beginner's Questions

As a really new beginner for BEx, I would like to ask you guys some basic questions.
1) I have a problem with designing a query to serve our requirement.
Fiscal Year       Accounting Num.        Amount          AVG(Amount)
2006                10001                         100                250
2006                10002                         200                250
2006                10003                         300                250
2006                10004                         400                250
                       Total(AVG)                  250
2006                10005                         300                350
2006                10006                         400                350
                       Total(AVG)                  350
What I want is the forth column, which is equal to the average value of amount in the third column. For example, in group 1 (Accounting Number 10001 - 10004), the average of 100 - 400 is 250. In the forth column, I want to get 250.How can I do this?
2) How can I load a hierarchy from a text file in BI 7.0. I just see the option to maintain the hierarchy in BI, but I can't find the way to load the hierarchy from a text file.

Hi,
1.Create a formula or CKF which is equal to Amount. name it AVG(Amount).
right click AVG(Amount) in the query definition.select properties.select calculate single value as 'Average of all values<>0'.
i thnk this shld work!

Dhanya.

Need a comment for my program & questions.

Dear all,
I have just finished my simple project with LabView.
Actually, I have no much experience with LabView language.
Therefore I would like to hear your invaluable comments about using structure, variable, and some habits to write the program.
Please let me know if you find some bad thing or something should be escaped.
Regarding to my question, as you can see the status window(GPIB, RS-232, and Saving),
I would like to attach the common status window to main dialog with same structure (background).
But the status window couldn't seen in opening the window.
How can I modify it to see the status window in evey tab states?
Thank you in advance.

I think I would change the Tab control from the Windows style "Dialog Tab Control" to the standard LabVIEW style "Tab Control" - the Windows dialog style control does not fit in very well with the style/colouring of the LabVIEW control objects, and this is one reason why your status indicators don't integrate "visually" as well as they could.
I don't think it's possible to add an "always visible" part to a tab control, but there are one or two ways to "join" controls together...
1. You could simply use the "Group" front panel objects function in the editor taskbar - this will lock several independent objects together so that they move around together on the front panel (but are still seperate data terminals on the block diagram)
2. You could create a "Custom Control" or "Type Def" from several front panel objects - this way you could create a control which includes both a tab control and LED status indicators (etc, etc), all integrated into one single block diagram terminal/data structure (and is saved, so can be reused in other programs). This option might be a little cumbersome though, if you have many controls and indicators that you want to be included within your tab control (note: the control/indicators actually on the various tab pages do not have to be included in the custom tab type definition).
As regarding programming style - I think you need to try to not use "sequence structures" unless you really have to. I never use sequence structures except as a last resort. If by not using sequence structures the diagram becomes too large, then that is a sign that you might need to create mor sub VIs. Tip: All the sub VIs I create use the "error cluster" input/output, so it's allways possible to sequence sub VIs even when there is no data dependency.
Hope this helps.

Beginner SSL questions

I am still very much a beginner and this is my first time trying to set SSL up. I am experiencing some issues and I am not really sure what to do. I hope this is the right forum to post this.
When I go to https://xxxx.xxxxx.net/myContext my login index.jsp page displays however
1.) In IE it's not showing the page as secured(no lock).
2.) When I log in using valid credentials the url becomes http://xxxx.xxxxx.net:443/myContext/myServlet
and the page I expect to display doesnt. It only displays this:
3.) None of my stylesheets are being used.
When I go to http://xxxx.xxxxx.net/myContext my login index.jsp page displays perfectly and I am able to log in and do see the expected page.
Apparently I missed a step somewhere or just the obvious but how do I get my index.jsp to use SSL. Any help would really be appreciated. Thanks in advance

Are you intentionally leaving a connector for port 80 open? If you don't need anything to be non-ssl enabled then you should comment out the port 80 connector and just have a connector for port 443. You should then be able to access any of your stuff via https://whatever/whathaveyou...
[edit]
this is an obvious question but you didn't mention it so just in case - you did create a self signed server certificate and import that into the keystore right? (or use a commercial certificate and import that and the CA chain into your trust store)
