Commons VFS Example Shell

This page shows some examples to configure the classpath and use the VFS Example Shell.

All examples expect to be started from within the Apache Commons VFS source directory (refering to build artifacts as well as external dependencies in a local maven repository). Linux/Unix commands are marked with $ prompt, for sample Windows command you see a C:vfs> prompt.

Enabling the SMB provider from the sandbox:

$ REP=~/.m2/repository
$ LIBS=$REP/commons-logging/commons-logging/1.2/commons-logging-1.2.jar
$ LIBS=$LIBS:$REP/jcifs/jcifs/0.8.3/jcifs-0.8.3.jar
$ LIBS=$LIBS:core/target/commons-vfs2-2.1.jar:examples/target/commons-vfs2-examples-2.1.jar:sandbox/target/commons-VFS2-sandbox-2.1.jar
$ java -cp $LIBS org.apache.commons.vfs2.example.Shell
VFS Shell 2.1

   Virtual Schemes: [gz, zip, war, par, ear, jar, sar, ejb3]
> ls smb://Domain\User:PASSWORD@host/Users/

Using the ftp(s) provider:

C:vfs> set REP=\Users\USERNAME\.m2\repository
C:vfs> set LIBS=%REP%\commons-logging\commons-logging\1.2\commons-logging-1.2.jar
C:vfs> set LIBS=%LIBS%;%REP%\commons-net\commons-net\2.2\commons-net-2.2.jar
C:vfs> set LIBS=%LIBS%;core\target\commons-vfs2-2.1.jar;examples/target/commons-vfs2-examples-2.1.jar
C:vfs> java -cp $LIBS org.apache.commons.vfs2.example.Shell
