javac: invalid flag: Files\Java\jdk1.6.0_18;C:\Program

[darrell22]

Dear Experts,


Today, on Windows xp, I installed:
jdk-6u18-windows-i586.exe


I'm trying to do the simple business
of now running a simple program. The program
code DID work/run before on my old machine.
So, it's not the code.


I've changed the path, classpath, and java_path.


The symptom is:

cd C:\Program Files\Java\jdk1.6.0_18\bin

javac -classpath %classpath% C:\Notes\java\code2\Car.java

javac: invalid flag: Files\Java\jdk1.6.0_18;C:\Program
Usage: javac <options> <source files>
use -help for a list of possible options


javac -classpath %classpath%:. Car.java

javac: invalid flag: Files\Java\jdk1.6.0_18;C:\Program
Usage: javac <options> <source files>
use -help for a list of possible options



Here are the environment variables:


Path=
C:\Program Files\Java\jdk1.6.0_18\bin;C:\WINDOWS\system32;C:\ WINDOWS;C:\WINDOWS\System32\Wbem;
C:\Program Files\QuickTime\QTSystem\;C:\Program Files\Sonic\MyDVD;C:\cygwin\bin;C:\cygwin\usr\bin; C:
\cygwin\usr\sbin;C:\cygwin\sbin


CLASSPATH=
.;C:\Program Files\Java\jdk1.6.0_18;C:\Program Files\Java\jdk1.6.0_18\bin;C:\Program Files
\Java\jdk1.6.0_18\lib;C:\Program Files\Java\jdk1.6.0_18\\src.zip;C:\Program Files\Java\jdk1.6.0_18\l
ib\dt.jar;C:\Program Files\Java\jdk1.6.0_18\demo\jfc\SwingApplet\SwingA pplet.jar;C:\Program Files\Qu
ickTime\QTSystem\QTJava.zip


java_path is:
C:\Program Files\Java\jdk1.6.0_18



Does anyone know the secret to fix this???

Could it have something to do with the blanks in
C:\program files
???

Sorry for the seemingly dumb questions.
But this kind of nonsense gets me every time.

Thanks a lot!

Not a Java problem. That is a problem with the Windows command shell and the fact that you have spaces in the directory names. Place quotes around those arguments I.E. instead of

C:\Program Files\a\b\c;C:\Program Files\d\e\f

use

"C:\Program Files\a\b\c";"C:\Program Files\d\e\f"

You should be able to do it yourself, however. If you do not understand how to, and cannot, do it manually, you will be lost the first time you do not have that IDE. You will even be lost when you use other IDEs.

Thanks for your responses.

I noticed that JAVA_PATH did not take.

Reset JAVA_PATH to:
JAVA_PATH=C:\Program Files\Java\jdk1.6.0_18

And there was a blank in one of the other paths
around one of the ";" I removed it.

But still no quotes. Now I have:

CLASSPATH=.;C:\Program Files\Java\jdk1.6.0_18;C:\Program Files\Java\jdk1.6.0_18\bin;C:\Program Files
\Java\jdk1.6.0_18\lib;C:\Program Files\Java\jdk1.6.0_18\\src.zip;C:\Program Files\Java\jdk1.6.0_18\l
ib\dt.jar;C:\Program Files\Java\jdk1.6.0_18\demo\jfc\SwingApplet\SwingA pplet.jar;C:\Program Files\Qu
ickTime\QTSystem\QTJava.zip

Path=C:\Program Files\Java\jdk1.6.0_18\bin;C:\WINDOWS\system32;C:\ WINDOWS;C:\WINDOWS\System32\Wbem;
C:\Program Files\QuickTime\QTSystem\;C:\Program Files\Sonic\MyDVD;C:\cygwin\bin;C:\cygwin\usr\bin; C:
\cygwin\usr\sbin;C:\cygwin\sbin


Now it seems that the old syntax no longer works. Surprise!

Before I used %classpath%. Now that seems to cause issues.
At least if I have already defined the environment variable: classpath

cd C:\Notes\java\code2

javac -classpath %classpath%:. Car.java
javac: invalid flag: Files\Java\jdk1.6.0_18;C:\Program
Usage: javac <options> <source files>
use -help for a list of possible options


javac Car.java
- seems to work.


C:\notes\java\code2>java CarTest
- works.

I hope this will be all there is to worry about.

Stick with your thread on Sun. You are getting more detailed advice there. Not that you are actually paying attention to any of the advice you're getting.
