Re: importing QTJ into xCode

I know how to compile my program in the terminal using "javac - classpath

Can someone please tell me how to fix this?

Try doing nothing at all.  You shouldn't even need to name that file in the
'javac -classpath ...' command-line.  (By the way, there must be no space
between '-' and 'classpath'.)

The QTJava.zip file in that location is already automatically present in
your classpath, because it's installed as a Java extension, and Java
extensions are automatically placed in your classpath.

If you can't import a simple QTJ class, such as:
  import quicktime.Errors;

in a simple Java source file, then I suspect a permissions problem on
either QTJava.zip itself or one of the dirs leading up to it.  You do need
read-permission on the file, and r+x permission on the dirs, or the Java
extension mechanism will quietly ignore the files in that location.

If you're not sure how to fix permissions problems, post the output of this
command:
  ls -la /System/Library/Java/Extensions/

so we can see if it really is the cause.  If the command fails, then paste
the error message.

Hi Greg

thanks for the help

for some reason my computer does need the -classpath variable to be set (sorry about the space in my first post), here is the terminal output if i don't set it:

The code I am compiling is example one from Chris Adamson's book on QTJ where he says that  -classpath needs to be set. Here is the source code, just in case i have made a mistake (it does compile and run if I set the -classpath in the terminal).

import quicktime.QTSession;
import quicktime.util.QTBuild;

public class QTVersionCheck
{
public static void main (String[] args)
{
try
{
QTSession.open();
System.out.println ("QT Version: " + QTSession.getMajorVersion() + "." + QTSession.getMinorVersion());
System.out.println ("QTJ Version: " + QTBuild.getVersion() + "." + QTBuild.getSubVersion());
QTSession.close();
}

catch (Exception e)
{
e.printStackTrace();
}
}
}

I have used the "get info" box in the finder to test the permissions on all the folders and QTJava.zip and that says that I have read access on them all. The terminal results echo this, I don't have execute on QTJava.zip, but I do on all the folders.
