Access jar files in a library directory in the jar file
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: org.linfield.PreferencesManager.XMLPrefs
at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.java:190)

at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
... 1 more
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.

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/ )

You are right that it is inefficient, but it is easy to understand. If
you want to get efficient, you could create the main.jar with inclusions
of <zipfileset>[1] using the src attribute for the other jars.
As for the manifest, while this would be tricky for a general purpose
jar merging tool, it isn't a problem when you are creating a specific
JAR file. Presumably Earl knows what the combined manifest should look like.

That is a way to do it, but it is inefficient and does not deal with
manifest entries (which may or may not matter depending on your needs).
Many moons ago, I wrote a java program to do jar merging, where it
supports inclusion and exclusion expressions (so you can merge subsets
of a jars) and attempts to also merge manifest entry information. The
program is efficient in that it does not pre-extract the jar files, but
instead walks the jar structure when doing the merge.
Never made it into an Ant task. When I do need it, I just use the
<java> task to call it.
IIRC, at the time (many years ago) there was not much interest in such a
facility of merging jars so I never packaged it up as an OSS project.

It is fairly trivial to do. In your main jar target:
1. create a temporary directory
2. run the unjar task
3. jar up your main jar, including the contents of the temporary
directory
4. delete the temporary directory
See http://ant.apache.org/manual/Tasks/unzip.html for docs on the unjar
task.

In that case, is there an ant task that will enable me to explode the jar file and add the classes that way. I could simply explode the jars in my development hierarchy in Eclipse, but I would rather leave them untouched there and only explode them when I build the main jar file. I looked in the ant user's guide, and I couldn't find such a task, but is there a way to execute a short shell script from within the build.xml file?

Hi,

If you want to load classes inMyUtils.jarinto the class path for use
inMyJar.jar. These two JAR files are in the same directory and can't be

Hi Rob,
I don't think you can have JAR files inside the JAR file like that.

Re: Access jar files in a library directory in the jar file
Posted by Vimil Saju <vi...@yahoo.com>.
The JVM won't look into nested jar files for classes. Eclipse has a FatJar feature that lets you create runnable jars with nested jars within it.
for ant I think you can use one-jar. Here is a link http://one-jar.sourceforge.net/

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,
