beginner to Java

[notwist]

I am a beginner with Java. I just installed the Bouncy Castle provider and would like to test some sample codes to see if everything is correctly installed. I downloaded a zip file that contains all of the example code. My question is: Can I run this code straight from a folder on the desktop or does it have to be placed in a certain place in order for it to compile? I thought I all I need is the provider to start using the library. Is this correct or do I need some extra files?

Thanks in advance.

First of all, welcome to Java Forums.

After downloading samples what you have done. Try to open a file and compile? If so any errors?

Yes, you can, if you already set the bin folder in the classpath...
or if none, you have to compile it in the jdk's bin folder where javac.exe exists.

I set the PATH (both User and System variables) as C:\Program Files\Java\jdk1.6.0_05\bin in the Environmental Variables. Is this what you mean? OR do I need to another variable containing the location of the BouncyCastle provider?

Thanks for your help!

EDIT:
I set the CLASSPATH variable in both User and System variables to:

.;C:\Program Files\Java\jre1.6.0_05\lib\ext; C:\Program Files\Java\jdk1.6.0_05\jre\lib\ext;

but when I try compiling the code I'm getting the error. (cannot find symbol errors)
I followed all other rules yet it still will not compile.

[Eranga]

Can you put the complete compile error to see. Seems to me something wrong with your code. Are sure that your code is error free?

[notwist]

I think the code is error free since it's some example code supplied with BC. I checked the code to make sure that the package structure is setup properly and all the imported classes are present. I think it might be something with the classpath although the directory in the classpath does contain the providers.

Here is the errors along with my classpath:

Code:

C:\org\bouncycastle\crypto\test>

Am i compiling this correctly? is the classpath correct?
Thanks for helping me with this.

[sukatoa]

Debugging time!!!!

[notwist]

The code was sample code from the BC zip file plus they are all the same type of error. i think it might be something with my classpath or how i am compiling the program

I didn't even write this code but here it is anyways

Code:

package org.bouncycastle.crypto.test;

import org.bouncycastle.crypto.test.GOST28147Test;
import org.bouncycastle.crypto.test.GOST3410Test;
import org.bouncycastle.util.test.*;

public final class RegressionTest
{


    private RegressionTest() 
    { }; 
    
    private static Test[]    _tests = {
            new AESTest(),
        new DESTest(),
        new DESedeTest(),
        new ModeTest(),

    {
        for (int i = 0; i != _tests.length; i++)
        {
            TestResult  result = _tests[i].perform();
            System.out.println(result);
        }
    }
}

Seems to me few classes are can't find there. Like AESTest ans do many.

And also, set the class path as follows and try.

Code:

path=C:\Program Files\Java\jdk1.6.0_05\bin\

Then use javac to compile and java to run the application.

[notwist]

Hmm, I changed the classpath but i'm still getting those errors.

I tried compiling another example program and while it did compile, I got an error when I tried running it.

Code:

C:\Documents and Settings\Bill\Desktop\crypto-139\src\org\bouncycastle\crypto\examples>javac DESExample.java

C:\Documents and Settings\Carl\Desktop\crypto-139\src\org\bouncycastle\crypto\examples>java DESExample

So few classes are missing in you package. Are you sure you have collect the complete set of classes. As I said on my previous replay there are few classes missing, you get FileNotFoundException.

[notwist]

Are you talking about the last program I posted. I will have to look into this and see. But I thought only the Provider was needed to compile these programs? I guess i was mistaken.

May be. You can compile the code, because reference not used in compile time here. You have already done it. But you can't run it. Check what your provider want to do

[notwist]

I set the classpath to point to the provider, changed the security file, and checked everything yet I'm still getting these errors. This is getting annoying!

[bobleny]

Could you give a link or something so we can download the samples. I would like to check them out....

Yes, it could be a good point.
