Assume that the Foo class is part of the Java package <i>wombat.foo</i> but the above interface file is part of the Java package <i>wombat.example</i>. Assume that the Foo class is part of the Java package <i>com.wombat.foo</i> but the above interface file is part of the Java package <i>com.wombat.example</i>.
Without the "javapackage" typemap, SWIG will assume that the Foo class belongs to <i>wombat.example</i> class. Without the "javapackage" typemap, SWIG will assume that the Foo class belongs to <i>com.wombat.example</i> class.

Practically speaking, you should create a separate SWIG interface file, which is %import-ed into each SWIG interface file, when you have multiple Java packages: SWIG looks up the package based on the <b>actual</b> type (plain Foo, Foo pointer and Foo reference), so it is important to associate all three types with the desired package.
Practically speaking, you should create a separate SWIG interface file, which is %import-ed into each SWIG interface file, when you have multiple Java packages.
Note the helper macros below, <code>OTHER_PACKAGE_SPEC</code> and <code>ANOTHER_PACKAGE_SPEC</code>, which reduce the amount of extra typing.
"<code>TYPE...</code>" is useful when passing templated types to the macro, since multiargument template types appear to the SWIG preprocessor as multiple macro arguments.
