I developed an application that uses JPA (eclipse-link) and connects to a MySQL database. The application works as expected when run from eclipse. However when I export the project as a runnable jar I encounter problems when I run the application. It appears that the persistence.xml file could not be loaded.
I also do not have any problems if I extract the contents of the jar and execute the application.
I execute the application from the command line using the following command:
java -jar pivotmenu.jar
Does the persistence.xml file have to be specified in the MANIFEST.MF file?
This is the content of the MANIFEST.MF file.
Manifest-Version: 1.0
Rsrc-Class-Path: ./ pivot-core-1.4.jar pivot-tools-1.4.jar org.eclipse
.persistence.core_1.1.2.v20090612-r4475.jar org.eclipse.persistence.a
