[VFS] Retrieving a FileContent instance
I am trying to get a FileContent object from a FileObject
so that I can retrieve the value from getLastModifiedTime().
I am to successfully create FileObject using the following URI:
jar:file:/c:/neo/code/dist/crosssell.jar
when calling resolveFile on FileSystemManager.
However, when I call the following, I receive a NullPointerException on the
call to getLastModifiedTime() because DefaultFileContent's default
getLastModifiedTime()
method is invoked and it is simply not implemented to do anything useful.
// fsManager is a DefaultFileSystemManager instance.
FileObject fileObject = fsManager.resolveFile(deployFile.getFileName());
FileContent fileContent = fileObject.getContent();
long lastModTime = fileContent.getLastModifiedTime();
What is the correct way to reference a FileContent object. In my case,
I am interested in FileContent for jar files.
If I am misusing the API, please advise.
Thanks,
Rai

I ended up creating a local temp file to resolve my problem:
// TMP_DIR = "/c:/tmp"
File tmpDir = new File(TMP_DIR);
// TMP_FILE = "temp.jar"
File tmpFile = new File(tmpDir, TMP_FILE);
// pathToJar is the SFTP uri
FileObject fileObject = defFileSysMgr.resolveFile(pathToJar, fso);
// populate tmpFile from the SftpFileObject
FileUtil.copyContent(fileObject, defFileSysMgr.toFileObject(tmpFile));
// read the local jar file
FileObject jarFileObject = defFileSysMgr.resolveFile("jar:" + TMP_DIR + "/"
+ TMP_FILE);

Re: [VFS] Retrieving a FileContent instance

I was successful when using:
sftp://username:password@hostname
/apps/web/eis81/WLS81SP4/domains/neodomain/neo/dist/crosssell.jar
I also attempting to connect via an SFTP client and was successful.
Permissions are okay.
As part of the stacktrace, the following exception seems to indicate that an
attempt to create a
temporary file is being made. Do I need to configure a FileReplicator?
Caused by: org.apache.commons.vfs.FileSystemException: No file replicator
configured.
This code works and returns an SftpFileObject:
// pathToJar - sftp://username:password@hostname
/apps/web/eis81/WLS81SP4/domains/neodomain/neo/dist/crosssell.jar
FileObject fileObject = defFileSysMgr.resolveFile(pathToJar, fso);
This code does not and causes the exception above:
defFileSysMgr.resolveFile("jar:" + fileObject + "!/", fso)
fso is defined as
fso = new FileSystemOptions();
SftpFileSystemConfigBuilder.getInstance().setStrictHostKeyChecking(fso,
"no");
SftpFileSystemConfigBuilder.getInstance().setUserInfo(fso, new
TrustEveryoneUserInfo());
I am using VFS RC8.
Thanks,
Rai

Looks good to me. Try to copy the file without the jar: stuff, just to
see if you get successfully connected.

Re: [VFS] Retrieving a FileContent instance

I am attempting to retrieve the content of a jar resource via sftp with the
following:
jar:sftp://username:password@hostname
/apps/web/eis81/WLS81SP4/domains/neodomain/neo/dist/crosssell.jar!/
However, I receive:
Caused by: org.apache.commons.vfs.FileSystemException: Could not replicate "
sftp://username:password@hostname
/apps/web/eis81/WLS81SP4/domains/neodomain/neo/dist/crosssell.jar".
Is this syntax incorrect?
Thanks,
Rai

Hi!
> jar:file:/c:/neo/code/dist/crosssell.jar

If you would like to know the lastModTime of crossell.jar the url is simply
file:/c:/neo/code/dist/crosssell.jar
If you would like to access the content of the jar the url is
jar:file:/c:/neo/code/dist/crosssell.jar!/
or for a file within the jar it is
jar:file:/c:/neo/code/dist/crosssell.jar!/path/in/jar/file.txt
For sure it should throw a NPE with your url, but one of the urls above
should help.
Ciao,
Mario
