Hi All,

I really need help with this problem (at the end of my rope)...

(A) The application I created is Mu01.java - I placed in the directory below
with its supporting .zip/.jar files...

C:\Mu01>dir
Volume in drive C has no label.
Volume Serial Number is 24AB-038C

Directory of C:\Mu01

01/30/2001 09:18p <DIR> .
01/30/2001 09:18p <DIR> ..
04/10/2000 10:01a 1,552,313 classes12.zip
07/31/2000 11:56a 51,780 connectionmanager.zip
07/31/2000 11:56a 73,968 jdev-rt.zip
01/30/2001 09:01p 20 mfst
01/30/2001 10:56a 14,666 Mu01.java <---appl.
03/16/2000 06:03a 10,705,708 rt.jar
6 File(s) 12,398,455 bytes
2 Dir(s) 5,022,380,544 bytes free


(B) This directory also includes a "auxillary" file (i.e., mfst) with the
"Main-Class:" value, as shown...

C:\Mu01>type mfst
Main-Class: Mu01 <----- "Main-Class" information for manifest


(C) I ran javac agains the Mu01.java file to create the class files...

C:\Mu01>javac Mu01.java


(D) This is how my directory looked afterword (I removed the Mu01.java file
from the directory before running the jar utility)...

C:\Mu01>dir
Volume in drive C has no label.
Volume Serial Number is 24AB-038C

Directory of C:\Mu01

01/30/2001 09:25p <DIR> .
01/30/2001 09:25p <DIR> ..
04/10/2000 10:01a 1,552,313 classes12.zip
07/31/2000 11:56a 51,780 connectionmanager.zip
07/31/2000 11:56a 73,968 jdev-rt.zip
01/30/2001 09:01p 20 mfst
01/30/2001 09:25p 1,069 Mu01$1.class
01/30/2001 09:25p 1,025 Mu01$2.class
01/30/2001 09:25p 698 Mu01$3.class
01/30/2001 09:25p 1,100 Mu01$4.class
01/30/2001 09:25p 781 Mu01$5.class
01/30/2001 09:25p 870 Mu01$6.class
01/30/2001 09:25p 533 Mu01$7.class
01/30/2001 09:25p 973 Mu01$8.class
01/30/2001 09:25p 507 Mu01$9.class
01/30/2001 09:25p 9,455 Mu01.class

03/16/2000 06:03a 10,705,708 rt.jar
16 File(s) 12,415,466 bytes
2 Dir(s) 5,022,361,088 bytes free


(E)Then I ran the JAR utility to with the "m" option to specify (via the
"auxillary" file: mfst) the "Main-Class:" value...

C:\Mu01>jar cvfm Mu01.jar mfst c:\Mu01\*.*
added manifest
adding: c:/Mu01/classes12.zip(in = 1552313) (out= 547459)(deflated 64%)

adding: c:/Mu01/Mu01.class(in = 9455) (out= 4628)(deflated 51%)
adding: c:/Mu01/rt.jar(in = 10705708) (out= 3823354)(deflated 64%)


(F) After creating the Mu01.jar file (above), I attempted to execute the
Mu01.jar application, ... but, I am unsuccessful...

C:\Mu01>java -jar Mu01.jar
Exception in thread "main" java.lang.NoClassDefFoundError: Mu01


(G) H E L P ! ! ! - My Question is "Why do I get a "NoClassDefFoundError"
after I have specifically included the "Main-Class" information in the JAR
creation????

What am I doing wrong, what am I leaving out of the manifest, etc...???


Really would appreciate the help

thanks!
