================================================================================ How to repeat the problem: 1. Checkout org.eclipse.filesystem.ftp plug-in from CVS (I removed the dependency on org.osgi.core and modified Keyring.USER, Keyring.PASS to "anonymous" and "abc@sourceforge.net" to get it compiled. The user name and password is valid for ftp.leo.org). 2. Create a new project, e.g. TestFTPFilesystem 3. Since there is currently no UI support available, manually edit .project and insert the following part to manually create the linked resources <linkedResources> <link> <name>WELCOME.TXT</name> <type>1</type> <locationURI>ftp://ftp.leo.org/WELCOME.TXT</locationURI> </link> </linkedResources> 4. save .project, and an icon for the file WELCOME.TXT appears with a ! sign on it. 5. Double click on WELCOME.TXT and an error message pops up which simply say that an error has occured. The following logs are available: !SESSION 2006-04-20 23:18:02.984 ----------------------------------------------- eclipse.buildId=unknown java.version=1.5.0_04 java.vendor=Sun Microsystems Inc.

Created attachment 40856 [details] patch for linked folder on ftp file system I have worked out a partial solution. It works now for directories like <linkedResources> <link> <name>ftp.leo.org</name> <type>2</type> <locationURI>ftp://ftp.leo.org/</locationURI> </link> </linkedResources> More efforts are still required for files to work.
I have released this patch. Thanks Tianchao.
