The compiler needs to be able to locate the base of your package structure through the CLASSPATH setting. So, the folder that holds the pack folder, needs to be somehow included in the CLASSPATH. Try the following. (I'm working from my K:\java\temp folder.) 1. Create the pack folder - K:\java\temp\pack 2. Inside the K:\java\temp\pack folder, create parent1.java 3. From the command line, cd to K:\java\temp\pack and compile. K:\java\temp\pack> javac parent1.java It should compile successfully. 4. Inside the K:\java\temp\pack folder, create child1.java 5. From the command line, cd to K:\java\temp (NOT K:\java\temp\pack) and compile. K:\java\temp> javac pack\child1.java It should compile successfully, if your CLASSPATH is configured to include the current working directory (specified with a simple . - period). If it doesn't compile, then fix your CLASSPATH accordingly. Feel free to ask about how to do so. 6. You can now run the child1 program from the command line. K:\java\temp>java pack.child1 And it should output the following. Hello Hello Neelima Paramsetty 7. Any luck? [ April 12, 2004: Message edited by: Dirk Schreckmann ]
Using an IDE Tool will ease your classpath stress as you can setup/edit/customise them for individual projects. Try using Forte by Sun Microsystems for example..its free.

Let me suggest that once you figure out the whole CLASSPATH thing, it's easy. I'd suggest not using an IDE at first. Using one will hide some of those details that a programmer might do well to be familiar with.
