Problem with JARs and External Libraries
Hi,
My problem is: I have a Eclipse project that uses external libraries (in the project properties--> Java Build Path --> Libraries I add all the jars I need and then they appear in my project with a white simbol) and it works running in Eclipse ( My project have a fold called "lib" containing all the libraries' jars). I want to export my project into a executable .jar
Firstly I exported the projecte into a .jar, and it makes a MANIFEST file:
Manifest-Version: 1.0
Main-Class: control.Launch
I tried to run with "java -jar MentalPoker.jar" but it said me that :
Exception in thread "main" java.lang.NoClassDefFoundError: iaik/me/security/CryptoException
I search in a lot of forums. A lot of people had this problem and de solution was to modify the MANIFEST and to use it at the moment to export (I specify in Eclipse that I want to use an existing manifest in worspace)
Manifest-Version: 1.0
Main-Class: control.Launch
Class-Path: lib/cldcapi11.jar lib/iaik_jce_full_me.jar lib/kxml.zip lib/midpapi20.jar lib/mysql-connector-java-3.1.12-bin.jar
but it dosn't work :( I run the .jar and the console say me the same initial problem:
Exception in thread "main" java.lang.NoClassDefFoundError: iaik/me/security/CryptoException
The libraries isn't found...
what can I do?
Thanks!

I execute the JAR by command line, I go to the path that contains the file and then write "java -jar MentalPoker.jar":
C:\Documents and Settings\Suu\Escritorio\PFC>java -jar MentalPoker.jar
Exception in thread "main" java.lang.NoClassDefFoundError: iaik/me/security/CryptoException
the IAIK is the cryptographic library that I need to use and it doesn't find.
My data follow this escructue:
-A fold called MentalPoker (this fold is the project's fold) that contains:
-".settings" fold
-"class" fold that contains all the .class
-"lib" that contains all the libraries that I have exported to my project
-"metadata" that contains a .sql file
-"src" that contains all .java files (contains the folds: utilities, files, exceptions, dataStructures, dao, files and control )
-a file named ".classpath"
-a file name ".project"
that's all
when I do the .jar and I open it with winrar and I saw this estructure:
-utilities fold
-files fold
-exceptions fold
-dataStructures fold
-dao fold
-control fold
-files fold
and META-INF fold that contains de MANIFEST
that's all
do you know what can be the problem?
Thanks

Sorry, the .jar has got more folds...
when I do the .jar and I open it with winrar and I saw this estructure:
-utilities fold
-files fold
-exceptions fold
-dataStructures fold
-dao fold
-control fold
-files fold
-META-INF fold that contains de MANIFEST
-lib fold containing all the .jar libraries
-metadata fold
if I open the MANIFEST that the .jar contains... I see that it not contains the Class-Path, only the version and the main-class. Why? The metadata that I use to generate the JAR contains Class-Path!!

I don't understand why the MANIFEST file that I use to export my project is diferent that the MANIFEST file that the JAR contains.
I use:
Manifest-Version: 1.0
Main-Class: control.Launch
Class-Path: lib/cldcapi11.jar lib/iaik_jce_full_me.jar lib/kxml.zip lib/midpapi20.jar lib/mysql-connector-java-3.1.12-bin.jar
and the JAR has got only:
Manifest-Version: 1.0
Main-Class: control.Launch
And... now my .JAR has got all the libraries' jars inside. it is incorrect?
if it isn't incorrect... why can I do?
thanks!
