Hi,
I'm using VFS in a small homegrown CMS project to copy whole folder trees
about in a platform independant way.
Here's some code with "CMSMount", "destDir", and "src" all strings
containing system paths.
FileSystemManager fsm = VFS.getManager();
File destDir = new File(CMSMount+"/"+target);
if (destDir.exists()) {
File file = new File(CMSMount+"/"+src);
if (!file.exists()) {
throw new EventHandlerException("source "+src+" not
found");
} else {
Logger.debugLog("copying "+ file.getAbsolutePath());
FileObject srcObj = fsm.toFileObject(file);
FileObject targetObj =
fsm.resolveFile(CMSMount+"/"+target);
Logger.debugLog("src object:
"+srcObj.getURL().toString());
targetObj.copyFrom(srcObj, new AllFileSelector());
targetObj.close();
srcObj.close();
}
}
This code works fine when the system is started up and after you have
changed existing files in the source folder.
However, if you add a new file to the filesystem seperately and then run
the above code it fails with:
org.apache.commons.vfs.FileSystemException: Could not copy
"file:///path/to/source/filename.html" to
"file:///path/to/target/filename.html"
I assume that this is because the vfs system keeps the filestructure in
memory and cannot cope with new files being added.
Is there anyway to refresh the FileSystemManager object?
