How do I set the classpath to access JARS contained within a Jar File

[Rob Tanner]

Hi,

I am trying to build a single jar file containing two executables and the jar files they need to function (i.e., for MySQL access, to mail results, XML processing, log4j, etc). There is no default class and therefore each of the two executables are accessed by it's full package name with the CLASSPATH environment variable set to the name of the containing jar file, e.g.:

PROPERTIES=/usr/local/adm/pcounter/PcounterLog4j.properties
HEAPSIZE="-Xms1024m -Xmx2048m"

STUDENTS=org.linfield.Papercut.Billing.PaperCutMonthlyStudentBilling
EMPLOYEES=org.linfield.Papercut.Billing.PaperCutMonthlyEmployeeBilling

export CLASSPATH=${EXEC_DIR}/Papercut.jar

cd $EXEC_DIR
${JAVA_BIN}/java ${HEAPSIZE} $STUDENTS $PROPERTIES
${JAVA_BIN}/java ${HEAPSIZE} $EMPLOYEES $PROPERTIES

Inside the manifest, I am setting the Class-Path attribute to "lib/mail.jar lib/log4j-1.2.15.jar lib/xmlrpc-2.0.1.jar lib/xerces.jar lib/pcng-server-11.6.jar lib/commons-codec-1.3.jar lib/linfield.jar" which is their path within the jar file. The problem is that java isn't finding them. Am I doing something wrong or trying to do something that isn't supported in Java 6?

Thanks,
Rob Tanner

Rob,
Java isn't designed to read nested jars. Any reason you can't unjar it and have the jars "loose"?
