Rob,
There are various open source solutions out there to do what you're
looking for, but there is no "built-in" way to do what you want to do
using plain Java. I saw someone else suggest one-jar which is what I
would have suggested, too. There is another one called Meta Jar that
basically does the same thing. (http://www.yagga.net/java/metajar/ )

Hi,
I'm trying to build a runnable jar file that includes several libraries that
are also jar files. My problem is that Java does not seem to be able to find
the libraries. I get this message when I try to run the jar file:
java -jar LibraryAlmaInterface.jar
Exception in thread "main" java.lang.NoClassDefFoundError:
org/linfield/PreferencesManager/XMLPrefs
at org.linfield.Library.PatronDataTransfer.<clinit>(Unknown Source)
Caused by: java.lang.ClassNotFoundException:

You can see from the table of contents that the c;ass file is there:
jar tf LibraryAlmaInterface.jar
META-INF/
META-INF/MANIFEST.MF
lib/
org/
org/linfield/
org/linfield/Library/
org/linfield/Library/Workers/
lib/jsch-0.1.49.jar
lib/linfield.jar
lib/log4j-1.2.15.jar
lib/xerces.jar
org/linfield/Library/CalculateBarcode.class
org/linfield/Library/PatronDataTransfer.class
org/linfield/Library/Workers/MyUserInfo.class
org/linfield/Library/Workers/PatronLoadsXML.class
org/linfield/Library/Workers/SecureFTPHandler.class
And the linfield.jar contains the class that the loader can't find:
META-INF/
META-INF/MANIFEST.MF
org/
org/linfield/
org/linfield/PreferencesManager/
org/linfield/PreferencesManager/PreferencesParser.class
org/linfield/PreferencesManager/XMLPrefs.class
org/linfield/PreferencesManager/XMLPrefs.java
org/linfield/PreferencesManager/PreferencesParser.java
And the manifest in linfield.jar is:
cat META-INF/MANIFEST.MF
Manifest-Version: 1.0
Created-By: 1.4.0 (Sun Microsystems Inc.)
And most importantly, here is the main MANIFEST.MF file (for
LibraryAlmaInterface.jar):
cat META-INF/MANIFEST.MF
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.8.3
Created-By: 1.6.0_45-b06-451-11M4406 (Apple Inc.)
Built-By: rtanner
Main-Class: org.linfield.Library.PatronDataTransfer
Class-Path: lib/jsch-0.1.49.jar lib/linfield.jar lib/log4j-1.2.15.jar
lib/xerces.jar
I'm assuming that the problem is with the manifest, but I have no idea what it
is. Any help would be greatly appreciated.
Thanks,
