Help with JAR creation please

Question

I've created a JAVA program with the Forte IDE and now I want to make it executable without the IDE. I read on this forum that all I had to do was create a JAR file, so I tried but I get an error (see below). Could someone point out my error please.
Also, I tried to run the jar command by itself, I received a command not found error. Only when I preceeded the jar command by JAVA (i.e. JAVA -jar ....) did DOS attempt to run the command.
Second request: Am I missing the path to the jar command in my path variable?
Directory Tree:
vio082\vio\app\
DOS command to create executable JAR:
"java -jar cmf trackerManifest.txt trackerTest.jar trackerTest.Class"
ERROR I RECEIVED:
"Exception in thread "main" java.util.zip.ZipException: The system cannot find the file specified
at java.util.zip.ZipFile.open<Native Method>
at java.util.zip.ZipFile.<init><Unknown Source>
at java.util.zip.ZipFile.<init><Unknown Source>
at java.util.zip.ZipFile.<init><Unknown Source>"
This was my file trackerManifest.txt:
Main Class: trackerTest
[cr]
This is the begining of my file trackerTest.Class:
package vio.app;
import javax.comm.*;
import vio.tracker.*;
import java.net.*;
import java.io.*;
public class trackerTest {
public static void main (String argv[]) {

Hi there,
I'd like to get in on this as well ... I've got a problem of my own with this. In the past I've created packages and ran them alright. And I create my own .jar files all the time on MS Win OS's, which I distribute for others and create desktop shortcuts for, etc. ... no problems; I sometimes jar up applications in unix, even though pretty much everything I run there is command line, just to keep things together.
But I've never jar'd up an application with my OWN packages inside, rather than just the default directory path (IOW: with package statements) and now that I'm trying it's not working quite right ... here's the deal:
Here's the path to the 1st package level: C:\MyMoveSubDir\Mysendrecv\Billsdir\TestPgms
Here's the next dir level:
mytestdir
So, in C:\MyMoveSubDir\Mysendrecv\Billsdir\TestPgms\mytestdir is:
TestClassy.class
and
TestClassy$P1.class
... created from:
TestClassy.java ... the source is:
package mytestdir;
public class TestClassy {
public static final void doNothing() {
System.out.println("What a doNothing method");
protected class P1 {
void afancymethod() {
System.out.println("What a fancy method");
public static void main(String[] argv) {
TestClassy tc = new TestClassy();
tc.doNothing();
P1 p1 = tc.new P1();
p1.afancymethod();
... The manifest file is called mymanifest.txt, and is in:
C:\MyMoveSubDir\Mysendrecv\Billsdir\TestPgms, and looks like this:
Main-Class: mytestdir.TestClassy
I compile the pgm from C:\MyMoveSubDir\Mysendrecv\Billsdir\TestPgms like this:
javac -classpath . mytestdir\TestClassy.java
I run the pgm from same like this:
java -classpath . mytestdir/TestClassy
... and it prints:
What a doNothing method
What a fancy method
...fine.
I can jar it up like this:
C:\MYMOVE~1\MYSEND~1\Billsdir\TestPgms>jar cvfm TestClassyJar.jar mymanifest.txt -C mytestdir/ .
added manifest
adding: mytestdir/./(in = 0) (out= 0)(stored 0%)
adding: mytestdir/./TestClassy$P1.class(in = 594) (out= 374)(deflated 37%)
adding: mytestdir/./TestClassy.class(in = 681) (out= 436)(deflated 35%)
adding: mytestdir/./TestClassy.java(in = 423) (out= 214)(deflated 49%)
But no matter how I try to execute it - like this - it fails with:
C:\MYMOVE~1\MYSEND~1\Billsdir\TestPgms>java -jar TestClassyJar.jar
Exception in thread "main" java.lang.NoClassDefFoundError: mytestdir/TestClassy
... any suggestions anyone. I'd sure appreciate it.
