META-INF/MANIFEST.MF is a text file that is included inside a JAR to specify metadata about the file. Java’s default ClassLoader reads the attributes defined in MANIFEST.MF and appends the specified dependencies to its internal classpath. The encryption plug-in ID is the value of the Bundle-SymbolicName property in the manifest file for the encryption plug-in. You need to change this property when you deploy multiple instances of the default encryption plug-in, as described later in this chapter.
Listing 29-2 shows the contents of the default MANIFEST.MF.
