Typical packages problem!!!!

Hi,
can someone please help?
i have java files arranged like this:
c:\lax\prog\sun\ui\*.java
c:\lax\prog\sun\db\*.java
java classes in the package UI need java classes in the package DB.
And my typical java class file, in package UI looks like this:

package sun.ui
import sun.db.*;
class XX{}
There's a compile time error saying can't find sun.db package and can't resolve symbol.....
where am i missing???
my javac command line option is:
c:\javac -classpath c:\lax\prog\sun\db c:\lax\prog\sun\ui\*.java

if your package is sun.ui, then your classpath needs to be set to allow the JVM to find your package, starting with "sun". You're going too deep into the package hierarchy when you define your classpath. The JVM just needs to look inside \lax\prog to find your packages, so your classpath should be just "c:\lax\prog "
And your javac call should be:
c:\javac -classpath c:\lax\prog c:\lax\prog\sun\ui\*.java

Your command line should be this:

This is saying "Compile all the java files in c:\lax\prog\sun\db\ and c:\lax\prog\sun\ui\ directories AND when you do that be sure to use c:\lax\prog\ as the classpath.
Remember, when a file is in a package the compiler and JVM wil automatically add that directory structure to the class path. So if you have your classpath set to c:\lax\prog\ and you have a file that is in the package sun\db then the compiler will actually look for that file in c:\lax\prog\sun\db WITHOUT you having to specify the classpath for each file. That's why you only have to specify one directory for your classpath.
The way you had it the compiler was actually looking for your file in c:\lax\prog\sun\db\sun\db
Hope it helps.

Hi Rob and Greg,
Thanks alot!!!
That was a fast reply.
Its working fine!!!
yes what u've said is right. I need to put c:\lax\prog after javac -classpath.
Thanks again,
Sri
