I have the following example working. Hopefully it helps point you in the right direction.
Folder structure:
jdbctest
- classes
- lib
- mssql-jdbc-8.2.2.jre8.jar
- src
- JDBCTest.java
Files:
JDBCTest.java
import java.sql.Driver;
import java.sql.DriverManager;
public class JDBCTest {
public static void main(String[] args)
{
try
{
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Driver sqlServerDriver = DriverManager.getDriver("jdbc:sqlserver://localhost");
System.out.println(
sqlServerDriver.toString()
+ ":" + sqlServerDriver.getMajorVersion()
+ "." + sqlServerDriver.getMinorVersion()
);
}
catch (Exception ex)
{
System.out.println(ex.getMessage());
}
}
}
Commands (run from project directory):
javac -d classes src/JDBCTest.java
java -classpath classes:lib/* test.JDBCTest
It should print out "SQLServerDriver:1:8.2".

Wow! That is a really great detailed example. Thanks so much.
I'm going to try it right now. I'll set it up exactly like yours and we will see what happens.
Thanks again. I will let you know.

I set up everything exactly the same as you showed, but I did have to alter a couple of things to get it working...
When I ran java -classpath classes:lib/* test.JDBCTest from the project directory, I got an error that said:
Error: Could not find or load main class test.JDBCTest
If I run it successfully from the classes directory, it throws an exception that outputs:
com.microsoft.sqlserver.jdbc.SQLServerDriver
I believe the test.JDBCTest is not correct on the last line in your example, but I'm not sure. Seems like that would have it in a pkg named test, right?
I'm hacking around but still don't quite have it. Thanks

Wow!! I finally figured it out because I screwed around with -classpath so much!!.
I'm on Windows so the separator has to be ; not a :
Once I did that your instructions worked with the following java command:
java -classpath classes;lib/* JDBCTest
Notice I removed the test. (pkg name) and I changed the : to a ;
While trying to get it working, I changed the output to have separate lines :
SQLServerDriver:1

Thanks so much, you got me there. Phew...

Well, it's quite realistic for once!

That makes sense if their evil plot is to take over the world and turn us all into robots androids!
If you can't laugh at yourself - ask me and I will do it for you.

True or not, this story made me lough. Especially the harebrained attempt to cover up the 'problem' and the reaction when it led to some questions. Girl, I have a solution. It's a box of latex gloves. I use them when I spray around with paint or whenever I don't want to get something else on my hands. Leave my socks alone.
Let's say this is not safe for work, even if nothing offensive is shown:

Your link has a time in it, so it starts with the second story.
That was NOT funny and the latex gloves advice doesn't make sense with that, so I figured you must've meant the first story.
I really don't know what to say about that one... 
The first is just weird, the second is sad and I think she cheated and wants to make him the bad guy, the third was sweet.

Thanks. I corrected it.
Sander Rossel wrote: The first is just weird
Indeed. Time to move to another planet. How about 40 Eridani?
Sander Rossel wrote: the second is sad
Depends on how you see it. Getting rid of her is the best he can do at that point. May the forgiving idiot subroutines in my (or anyone elses) head ever be called.
Sander Rossel wrote: the third was sweet
Except for his loving idiot subroutines already taking most of his brain's capacity. Often enough that leads right to the second story. Why behave when the idiot is blind and deaf?
Sander Rossel wrote: Some people really have a knack for drama
Yes, women. Have you noticed how the first two automatically tried to make everything the men's fault because they dared to ask questions? The best defense is a good offense, but that's insane. I would not put up with it, not even in smaller matters.

Yeah, but if I am to believe this guy there was nothing wrong.
She went from normal loving wife to bitch to divorce in a day.
So that's sad.

Yes, these two women.
I know men can be real drama queens too.
Overall, I think men and women deserve each other 
CodeWraith wrote: I would not put up with it, not even in smaller matters.
Me neither.
I have in the past.
My last girlfriend got mad at me because she didn't like the music I was playing while she was in the bathroom doing her morning routine, apparently she could hear it.
She also told me I couldn't buy Lego using my money (she still lived with her parents and didn't have a job).
And whenever I disagreed with whatever she said, we were in a fight.
Lasted about six months, but I wasn't particularly sad that one ended.
I decided then that I'd rather be alone than with the wrong girl and I've been alone ever since.
I ran into her father a while back, he's a cool guy, said she has a new boyfriend and added "poor guy"

Solution: buy her a bunch of socks to use as she see's fit, and leave your's alone ...
Latex gloves don't flush well, and aren't suitable for sewage recycling.

I thought about using the gloves and toilet paper. Flush the paper, dump the gloves in the trash can. Taking off the gloves without getting your hands dirty in any way is a no brainer.
Did I ever mention that I spent an entire summer running around in rubber suits, learning to detect and decontaminate nuclear fallout, chemical weapons or bioweapons?

Maybe it's because I started listening at the timecode Sander pointed out, but I only lasted for about 2 minutes (and that includes the ad that interrupted the whole thing 8 seconds into it). I'm sure it's a great rant and you need to listen to the whole thing to appreciate it, but there's only so much I could take of this guy's whiny rambling. A voice talent he's not.

So in terms of prep, communication with drivers is always fun. The MIDI API under windows gives you close to the metal access to the underlying driver, but dealing with it is tricky
Basically the trick of it is you have these MIDIEVENT structs in C and they can be *variable length*!!!
The variable part comes at the end of the core struct and must be multiples of 4 bytes long. You must pack these MIDIEVENT structs end to end in a single vector in memory before sending it to midiStreamOut
The .NET P/Invoke marshaller thing simply cannot deal with variable length structs meaning you wind up using Marshal.StructureToPtr(), Marshal.Copy() and/or Marshal.WriteByte(), etc yourself to construct your data.

Because of this really weird edge case you never need unless you're codewitch?

I believe I was in college when I started playing around with C (self-learning). I loved the expressiveness, and was sold on it at that point. Then, as I played around more and more, I started bumping into situations where the logic was becoming nested so deep that it became painful to keep track of. (IE, 7 level deep 'if' statements.)
When I finally got my head around C++, those logic nightmares vanished with the magic of virtual functions. It was a HUGE shift, and magnificently freeing.
I've always wondered why so many like yourself seem to love C so much, given that its syntax (was?) so easy to become ugly, with all the casting involved, and can fairly easily get the deeply nested logic I encountered. I'm not asking to attack C, just curious as to whether I'm overlooking something big, since most C stuff can be done in C++ if you chose not to use objects. And if you slightly objectify things, the casting is reduced.
Thanks!

Working in C, and doing it well, requires an unusual level of discipline. For many years, I worked in a similar proprietary language. But it had better typing and other concepts alien to C (more like Modula, say), which was one reason we could compete with larger firms that used C.
Much of our better software was rather object-oriented, but it was done manually. A struct containing function signatures would be defined. This was effectively an abstract class. A concrete class would populate it with function pointers and register it against a type index so that it could be invoked polymorphically, through an array of such structs. There were even some ad hoc examples of inheritance.
Building these things by hand was tedious, but it worked well when people took the time. Naturally, there were also horrors like deeply nested functions, a surfeit of global variables, obscure side effects, and bugs fixed by
IF(the conditions under which bug report#aannnn occur are true)
THEN
update a little of this and a little of that so the code can carry on successfully;
ENDIF;
This isn't necessarily a problem restricted to procedural languages, but I find that C++ does a better job of encouraging one to find the root causes of problems instead of working around them, which helps to both keep the code cleaner and evolve the system. Not to mention that having polymorphism, inheritance, and encapsulation built into the language saves a lot of time!
