Re: Exception when using vsf:poller with sftp (ServiceMix 4.2)
Hi,
Seems we need add javax.crypto package import for
org.apache.servicemix.bundles.commons-vfs bundle.
Could you do a quick test to verify it?
You can change the META-INF/MANIFEST.MF of
$SMX4_home/system/org/apache/servicemix/bundles/
org.apache.servicemix.bundles.commons-vfs/1.0_3/
org.apache.servicemix.bundles.commons-vfs-1.0_3.jar
add javax.crypto for Import-Package.

Hi,
I tried to use servicemix-vfs component to import files from sftp server.
this is my xbean.xml file:
<vfs:poller service="esb:pollerService"
endpoint="vfs-poller"
path="sftp://user:password@hostIp/home/"
targetService="esb:bean"
period="10000"
deleteFile="false"
recursive="true">
</vfs:poller>
when i run servicemix server this poller don't worked, i don't see error
message in log file.
i changed the protocol to connect to ftp server and it work.
i don't know what's the problem in sftp protocol !!!

I have been trying vfs-poller recently with
'apache-servicemix-3.6.0-fuse-00-35' and I still have the same issue.
Is this the update only available on 'SMX4'? If so, how can I make it work
for the above SMX release?
I tried with the following dependencies
<dependency>
<groupId>org.apache.servicemix</groupId>
<artifactId>servicemix-vfs</artifactId>
<version>2011.02</version>
<type>jbi-component</type>

<dependency>
<groupId>commons-vfs</groupId>

Freeman, Lars
Adding the javax.crypto to Import-Package in META-INF/MANIFEST.MF did the
trick! I tested it sucessfully. However manipulating the MANIFEST.MF with an
editor and then repackage it did not work first. The MANIFEST.MF was always
invalid after this. So I checked out
http://svn.apache.org/repos/asf/servicemix/smx4/bundles/trunk/commons-vfs-1.0,
changed pom.xml and then build it. I added the javax.crypto package insinde
the <servicemix.osgi.import.pkg> element. Then bundle was okay and it
worked!
During the process of finding this bug two issues gave me a headache and I
have two proposals for enhancements:
1) The class StandardFileSystemManager which configures the different
FileProviders for webdav, SFTP, etc. is only create once after startup of
servicemix. This this is the case because the instance is retrieved from a
static singelton. See FileObjectResolver.java:46
if (manager == null) {
manager = VFS.getManager().;
}
This is bad because StandardFileSystemManager will never reconfigure itself
and be able to detect necessary support classes which have probaly added
later with new bundles.
I think FileObjectResolver should better create its own instance of
StandardFileSystemManager instead of getting the static one. Otherwise one
would have to restart servicemix completely to add new FileProviders.
2) It was very hard to track connection problems because
resolveToFileObject() throws only IOExceptions without the root Exception.
All details about a problem (wrong credentials, unknown host for SFTP
connections, etc.) are not available for logging and tracking.
I had to run a dedicated test with the jsch Library to find out that a
connection failed because of a missing entry in .ssh/known_hosts. There was
no chance to make this visible in the servicemix log.
I think resolveToFileObject() should log those root exceptions or pass them
along with the IOException.
But most important I would like to thank both of you for your support. Now
my proof-of-concept works and chances are high that I will use servicemix in
our next customer project.
