question reg jar file

[ujjawal rohra]

Suppose ther is a file A.java which needs access to a file D.java located in file myjar.jar.
The directory structure in myjar.jar is B/C/D.java.
Then when using classpath i will have to state only the name of jar file or will i have to specify the directory structure also ??
such as myjar.jar/B/C

I believe the file D.java is in a "package B.C"
and you do "import B.C.D" in "A.java"
Assuming current dir is having myjar.jar and A.java

you have to use

   javac -classpath myjar.jar A.java // for compiling and
   java -classpath .:myjar.jar A // for running

But if B/C represents a directory structure and not a package then what will be the command???

Couple of things here:
1. For your A.java to run, you should have "D.class" in your jar "myjar.jar" (B/C/D.class)
2. Why is this particular requirement of putting D.class in B/C/D.class directory structure in "myjar.jar". Why can't you just create a jar "myjar.jar" and put "D.class" there?
3. Have you tried this yourself?
