I want to know is it possible to use a Single jar file which contains classes that uses other jar that helps for DB connection, logging. And the other jar should be in the same single jar. Or there might be a way if i extract all the jar into a single directory and append all the manifest info of all jars into single manifest file.
Note : The Class-Path header points to classes or JAR files on the local network, not JAR files within the JAR file or classes accessible over internet protocols. To load classes in JAR files within a JAR file into the class path, you must write custom code to load those classes. For example, if MyJar.jar contains another JAR file called MyUtils.jar, you cannot use the Class-Path header in MyJar.jar's manifest to load classes in MyUtils.jar into the class path.
