I am wondering, is there any way of replacing these

"Look in"
"File Name"
"Type of File"
"Cancel"

With language strings so I can support more than English? Am I wrong, maybe those translations already exist in Java but I need to set the localization somehow to get them??

Wow, that was a quick reply!
So you were able to mix them, that is great!
That is also what I intend to do on my project if I switch to openGL since the Swing UI is fast enough so I want to keep the advantages of the already built Swing components to not have to reinvent the wheel 

Doing openGL means switching to at leist a AWT Canvas. So wondering, has anyone tried mixing openGL with Swing? I have a JFrame which contains 3 swing JPanel and where my map and drawing is done in the center one. So one northPanel, southPanel, centerPanel

Is it possible to have the openGL canvas in center while still using Swing components in the north and south without them interfering with each others because that would be GOLD and means the switch from Swing to openGL would be much easier.

You are correct, the JWGL is inside the Slick. But regardless, both the jar files and the.Java files misses classes like GL11 for example. I placed all jars in the same place where I placed Jogg and Jorbis jars that I used from before but I cannot import certain classes because they do not exist.

Also, downloaded GL11.java from the Internet but when I compile I get


"GL11.java": illegal character: \64 at line 717, column 22"
"GL11.java": <identifier> expected at line 717, column 50"
...
...
...

errors everywhere



example of methods that give error.
void glAccum(@GLenum int op, float value);

Downloaded these 2 packages
lwjgl-source-1.1.zip
slick.zip

and extracted them in the correct path and tried using Slick.

There are still source files missing when I try to import
for example

import org.lwjgl.opengl.GL11;

By the way I am using Java 1.4 still (because my JDE does not support newer Java) now if that would have anything todo with it.

I am mostly drawing png's.

When I switched from my Java 5 to Java 6 my Swing drawing lost like 75% of its drawing speed so I had to basically either stay with Java 5 or switch to Java 6 and convert all my code using some better graphics engine. I chose to stay with Java 1.5 for the moment.

Now with Java 1.7 out, has anyone tried it and does it work well drawing Swing or do I need to get away from Swing to get enough frame rates to make a 2D game?

I have a pretty ok codebase in Java now but would like to speed up my drawing. I am currently using pure swing so I am totally platform independant. I have contact with a company that hold a good graphics engine written in C++ using DirectX.

Also, by the way I have 7 years experience in Java but only 1 year experience in C/C++

So, my question is what would generally be easiest?

1) Convert the C++ code to Java
or
2) Use my existing Java code and build my own graphical Java code for openGL or DirectX
or
3) Convert my whole codebase to C++ so I can use their Graphics

Please motivate your answer, this is a big decision for me to take 

I have code for reading a text file using

FileReader
StringTokenizer

The text file I had was ANSI. I now need to be able to read Unicode to support more languages. As soon as I made it a Unicode text file instead then my code threw exceptions instead. Why?

Ok, but I am talking about software being sold online and retail perhaps on several platforms so that is why I need to worry about ppl "steal and code reuse".

Ok, but if the code is like 200 classes spread out on 10 packages would that mean it was much easier for someone to pick out certain classes?

Note that I do not mean copy protection or piracy but rather protecting from ppl stealing code or entire classes using it as their own source code for making games.

So, why did they sue Microsoft for not showing the source code for Windows if it is that easy? Did it have something to do with themselves being afraid being sued if they went into Microsoft code? I searched on google today and found a software named Mocha that could decompile Java code and then you would be able to compile it again. On the same webpage there was a software that would prevent the Mocha from doing it by using this so called Crema software. Is that just waste of time because I recon there are certain ways of hacking that as well?

EDIT:
I was not clear enough, I did not mean protection from hack+piracy but rather protection from others hacking and ripping away copyrighted well structured code that they can use as their own source code when making games.



I heard that Java code is easy to decompile, can someone with knowledge in these kind of things explain that abit? I am wondering if it is possible to protect my code from being reverse compiled or not. I use obfuscator but is that really enough?

Was not Microsoft sued for not sharing their source code to other developers making integration to Windows difficult for the competing businesses? But windows is an Operating System and built from C++ so the lower the leve the easier to protect a code? It is obviously not so easy to decompile everything else they would have already done that with windows? Can someone compare the languages and compare other factors that decide this?

No, I did not make the exe myself. So, my code looks ok then? I should be talking to the guy who made that exe then.

I tried 2 ways:

i)
bos.write(123456);
bos.flush();


ii)
bos.write(123456);
process.getOutputStream().flush();


neither worked

It was easy starting an exe and getting return value. But now I want also to send parameters to it, alternatively start the exe with a parameter.

So, I tried.

Process process=Runtime.getRuntime().exec(Global.getInstallPath()+"myfile.exe");
     BufferedOutputStream bos = new BufferedOutputStream(process.getOutputStream());
bos.write(123456);


It seems the exe never receive those numbers and I do not know why...

The JRE seems to be 60-70 megs on the HD with roughly half of the size being jar files. Wondering, are these jar files (one is 35 megs) necessary or are they a doublette of something?

jre/lib/rt.jar is 35 megabytes, can it be deleted?


Also, is it even allowed by Sun to modify the JRE , I do not think so?

Bah!
Was kind of easy   

Process process=Runtime.getRuntime().exec("blablabla.exe");

      int i=process.waitFor();

I want to be able to start a windows exe from my Java and also communicate with. Say I send it some parameter and also when that exe is done to get its return value.

Runtime().getRuntime().exec

is that the way? How about the parameter passing between the exe and my Java game?

Thanks, saves me alot of time not trying to find something that does not exist

The java.io has alot of classes for reading and writing. I know I can use the path of my CD/DVD player to make java read from it but if I did not know the path, how can I detemine that during runtime i.e what path my primary cd/dvd device has?

When I am building a GridBagLayout i want to be able to come back and change settings later on. Reason is that I am doing a code reuse where I have a parameter named "boolean ripped" that determines if I want to show a small version of the panel. The small version might set some aubpanel to have size 0 effectively not showing certain parts of the panel.

I also want to be able to adjust insets

basicall

if(ripped==true)
{
blahblah;
blah;
blahblahblah;
}

so inside those begin and end I want to be able to modify insets. how?
I can easily fix it on creation but what if I want to be able to have a already created object with gridbaglayout and change the insets afterwards?

Is there a way to check whether a certain font exist on the machine so that I can pick a reserve font to use? I notice this already happens but I want to be able to select what font i want to use.

I am using Haettenschweiler for my Java Game and some ppl do not have it installed on their computers, hence it is no standard font. Is there a way (what about copyright) to distribute a font with my java game?

I am using Gridlayout with 30 rows and 1 column. Thinking of using 15 rows and 2 columns instead but I want to list the first 15 to the left and the last 15 to the right


1 2
3 4

is not what I want

instead

1 16
2 17
3 18
4 19
5 20
6 21
7 22
8 23
9 24
10 25
11 26
12 27
13 28
14 29
15 30



Any way to do it?

I think I might have found the problem. Will be able to see later on when I buy a second computer. The 2 threads I have all add their results into one OrderThread in game that has vector storing up all stuff and performing it into the game. Since both threads access the same OrderThread some problem may occurr. I have put synchronized keyword on all the public methods in the OrderThread class now, so I will see if that solve it

I have one thread running for chat and one for other actions and those 2 have separate ports. Despite that, I have experienced crashes that seem to occur when using the chat.

If I have a chat and both players send simultaneously then it woudl not crash?
Meaning, it is probably that the 2 different threads interfer somehow despite on different ports?
I am going to buy a second computer soon so that I can easier provoce these crashes myself and get an answer.

I heard other ppl also had the same problem. So is it a bad driver for the graphic card or for the display and is there no way for me to work around it?

If it is correct what you are saying then I should thank you very much because else I would probably spend alot of time (which I already have) bumping my head against a wall if I think it is the Java code fault.

So, is there no way to see that alt+tab coming and quickly set the full screen off before the alt+tab comes into effect (also tried it but never go it to work)?

Yes, a pure Swing application with NO openGL or anything.
