packaging problem

[padmshree Patil]

Hi All,
I am facing problem in packaging .
I have file testClass.java as

package java.first;
public class TestClass {
public void testShow(String str)
{ System.out.println (str);
}
}
and PackageTest file as
package MyPrgs.java;
import java.first.*;
public class PackageTest{

public static void main(String arg[])
{
System.out.println("Before calling Test funcion");
TestClass tc =new TestClass();
tc.testShow( "Testing from main");
System.out.println("After calling Test funcion");

}
}
TestClass.java file is compliling .But PackageTest.java file is giving err at
import java.first.*; as package java.first not found.
I do have correct directory structure.
Where am I wroung ?
Thanks
padmashree

Hi Padmshree,
I bet you don't have the correct directory structure!
Let's say you place all your java into the following directory for compiling and running:
c:\java\source\
Compile your TestClass file and place it in the following place:
c:\java\source\java\first
This is very important!! It you don't have the directory structure "java\first" relative to where you are going to compile the PackageTest file then you will get the error you are getting!
Compile your PackageTest file from the "c:\java\source" directory and you should have no problem. It worked correctly for me ...
Regards,
Manfred.

or could be a CLASSPATH problem -- what's your environment?

Hi,
I have set path to javahome. It's strange that if I copy PacakegeTest.java to root dir (c:\)
and then try to compile it works .It also runs.
I just comented package statement.
// package Myprgs.java;
import Myprgs.java.first.*;

class PackageTest{

public static void main(String arg[])
{
System.out.println("Before calling Test funcion");
TestClass tc =new TestClass();
tc.testShow( "Testing from main");
System.out.println("After calling Test funcion");

}
}

same file if I move to c:/Myprgs/java dir ,then uncoment package statement and try to compile it from c:/Myprgs/java dir gives err !!
TestClass.java is in
c:/Myprgs/java/first/ dir
What's wroung with this ???
Thanks,
padmashree

I gather that your base directory is C:\, right? That's where you execute the javac command from? We'll assume "yes" for the rest of this discussion...
You seem to have changed your package names around. Is "Myprgs" part of the package name, or not? In your first post, TestClass was supposedly in package java.first, indicating that it should be defined in a file located at C:\java\first\TestClass.java. (Not "testClass.java" as you indicated. CAPITALIZATION IS IMPORTANT.) But in your last post, TestClass is apparently in the package Myprgs.java.first - so I would expect it to be defined in C:\Myprgs\java\first\TestClass.java, with a correct package statement inside the file. You also seem to have changed MyPrgs to Myprgs - Windows may not care about the difference, but Java usually does. Pick names for your packages and classes, and use them consistently. When you change them around, we can't guess what you're talking about, and neither can your compiler.
