Subject Re: class path problem
Date Mon, 09 Oct 2006 15:18:54 GMT
WOW, guys thanks for the fast response, I really appretiate this help.
I am standing in the main directory (MyProject).
When I use -verbose I get alot of output, something like:

[javac] added as MyOp1.class doesn't exist.
[javac] added as Op1Helper.class doesn't exist.
...... then I get:

[javac] Compilation arguments:
[javac] '-d'
[javac] '/path/to/MyProject/resulting_classes_directory'
[javac] '-classpath'

There nothing states that the compiler is seeing the classes in the 
package MathOp, just like I expected.
I will do a search for how to use sourcepath attribute, and try it. I 
'll let you know if it worked, in the mean while, if you have any
suggestion, please let me know.
Thank you for every body.
