Importing Java Class Question

Question

Hello,
Sorry for such a newbie question and such a long post, I did remember how to do this before but now I can't for the life of me remember. Anyhow, I have a simple question about importing custom-made java classes, from another directory in the windows operating system. I have the classpath set, and also I realize that because the two files below are in the same directory theres no need for an import statement as Java will look for the class in the same directory.
But I would like to know how the import statement is suppose to look to import a custom made java class from another directory, (assuming of course that I set the correct classpath)
here's the java class location:
c:\school\csc365\narcus.java
//narcus.java
import java.io.*;
class narcus implements Comparable
String firstName = "firstName";
String lastName = "lastName";
     public narcus()
     firstName = firstName;
     lastName = lastName;
     public narcus(String f)
     firstName = f;
     lastName = lastName;
     public narcus(String f, String l)
     firstName = f;
     lastName = l;
public String getFirst()
return "first..";
     public int compareTo(Object e)
     return 1;
Here's the location of the driver program thats suppose to use the narcus.java class
c:\school\csc365\test.java
//test.java
//import statement? maybe import "c:\\school\\csc365\\*"; ?
import java.io.*;
class test
public static void main(String[] args)
     narcus jim = new narcus();
     System.out.println("omg\n");
     System.out.println(jim.getFirst());
And also, here is my classpath:
PATH=c:\school\csc365\;c:\school\
The classpath also points to the jdk libraries and few other directories but I didn't write that above, as it probably isn't relevant.
I've tried the following import statements.
import "c:\\school\csc365\\narcus.java";
import "narcus.java";
import "c:\\school\\csc365\\*";
But I keep getting an error that says:
test.java:1 <identifier> expected
Any help is appreciated!

Hi Folks,
I am new to this forum, heard that interesting discussions always happens on this forum so immediately registered,don't want to miss any oppurtunity to participate in discussions.
I have pretty much basic question regarding compiling and exceuting files in different packages.I have the following directory structure
C:\Projects\WDPROEast\Development\CommonService\Code\Java from where java files stored in different packages as follows:
com\wdpro\commerce\common\crm\dae\nautilus\adapter directory has java files in com.wdpro.commerce.coomon.crm.dae.nautilus.adapter package.
com\wdpro\commerce\common\dae\exception has java files with package named com.wdpro.commerce.common.dae.exception.
com\wdpro\commerce\common\dls\exception has java files with corresponding package name.
com\wdpro\commerce\common\dto has java files under proper package name.
com\wdpro\commerce\common\exception has java files with appropriate package name.
com\wdpro\commerce\common\util has java files with package name. I am starting at Java Directory,want to compile and run file named a.java in com.wdpro.commerce.coomon.crm.dae.nautilus.adapter package with having all other java files on classpath as follows
so I issued command for compilation as follows C:\Projects\WDPROEast\Development\CommonService\Code\Java>javac com/wdpro/commerce/common/crm/dae/nautilus/ada
pter/a.java com/wdpro/commerce/common/crm/dae/nautilus/adapter/NautilusServiceUtility.java com/wdp
ro/commerce/common/crm/dae/nautilus/adapter/URLReader.java com/wdpro/commerce/common/crm/dae/nautilus/adapter/
b.java com/wdpro/commerce/common/dae/exception/*.java com/wdpro/commerce/common/dto/*.java
com/wdpro/commerce/common/exception/*.java com/wdpro/commerce/common/util/*.java com/wdpro/commerce/common/dl
s/exception/*.java It compiled greatly but when I issue command to run a.class file as
C:\Projects\WDPROEast\Development\CommonService\Code\Java>java com/wdpro/commerce/common/crm/dae/nautilus/adap
ter/UtilityAccesssit's giving following exception
Exception in thread "main" java.lang.NoClassDefFoundError: com/wdpro/commerce/common/crm/dae/nautilus/adapter/
UtilityAccesssbut when I run a.java with the following command
C:\Projects\WDPROEast\Development\CommonService\Code\Java>java com/wdpro/commerce/common/crm/dae/nautilus/adap
ter/UtilityAccess com/wdpro/commerce/common/crm/dae/nautilus/adapter/NautilusServiceUtility.java com/wdpro/com
merce/common/crm/dae/nautilus/adapter/URLReader.java com/wdpro/commerce/common/crm/dae/nautilus/adapter/Nautil
usAccessUtility.java com/wdpro/commerce/common/dae/exception/*.java com/wdpro/commerce/common/dto/*.java com/w
dpro/commerce/common/exception/*.java com/wdpro/commerce/common/util/*.java com/wdpro/commerce/common/dls/exce
ption/*.javaSo my question do I need to add all required java files to path when required class files are under different packages?is it manadatory.
I hope you understand my question,pass me any comments you may have.
Thanks alot,
Anu
