Hi Bengt,
I just tried to use some file endpoint inside our camel OSGi test
platform, the route is started without any issue.
Can you create a small test case which is based on you application and
submit it into a JIRA ?
In this way I can keep on digging the issue :)

This is incredibly strange to me. It seems like the caller (line 145 in
class GenericFileEndpoint) cannot find the class
GenericFileProcessStrategyFactory. They both reside in camel-core so there
can be no problem in finding the class. However it is not exactly trying to
find it but to "resolve" it. The following call throws the exception:
factory =
this.getCamelContext().getClassResolver().resolveClass(DEFAULT_STRATEGYFACTORY_CLASS);
Any ideas?

Willem,
I'm just now building a new trunk version of Camel and need to verify with
you that I'm using Camel properly in an OSGi environment:
- I only install the features "camel" (includes camel-core and camel-spring
bundles) + camel-ftp (that I wish to test)
Do I need camel-spring if I'm not using Spring directly? I create all my
routes in Java DSL.
- I noticed that there is a component called camel-core-osgi. Should I use
it in any way? How?
Just out of curiosity. What was the typo you mentioned?

Hi Bengt,
It's a typo, I just fixed it with an OSGi unit test.
Please check out the last camel trunk code to keep on riding with Camel :)

I can reproduce the error that you met, there must be something wrong
with
current OSGi refactoring,
I will keep digging to see if I can fix this issue soon.

Thanks for your reply Willem,
I've tried various combinations of camel features. Right now I use the
"camel" feature (plus camel-ftp since that's what I'm trying to test).
In
runtime I can see the camel-core, camel-spring and the camel-ftp
bundles
installed and active. I manage to create an OsgiDefaultCamelContext the
following way:
mCamelContextFactory = new CamelContextFactory();
mCamelContextFactory.setBundleContext(theBundleContext);
mCamelContext = mCamelContextFactory.createContext();
However, when I try to start the camel context I get the exception I
mentioned above:
Caused by: org.apache.camel.ResolveEndpointFailedException: Failed to
resolve endpoint:

due to: No language could be found for: file
at
org.apache.camel.impl.DefaultCamelContext.getEndpoint(DefaultCamelContext.java:377)
To me it sounds like the languages has not been registered properly.
Looking
through the code it looks like the OSGi "registration" part of camel
has
moved from camel-osgi to camel-core. Which I guess means that I should
not
be using camel-osgi anymore (just camel-core in combination with
camel-spring). This is what I'm doing, but I still get the above
exception.
Could it be a problem with iPojo? I use iPOJO to create my OSGi
services
from configurations handled by file install. I noticed that the
BundleContext I'm using is really an instance
of org.apache.felix.ipojo.IPojoContext.
Any clues?

Hi Bengt,
Did you use the apache camel feature of the Camel 2.4-SNAPSHOT ?
If so, you just need to install the feature of camel, it includes the
camel-core feature and camel-spring feature.
And you can still use org.apache.camel.osgi.CamelContextFactory to
create
the camel context :)

Claus,
I have now managed to build Camel version 2.4-SNAPSHOT. However, I
can't
get
my application to work on that version. I'm using Karaf 1.6.0 for
deployment
and something has definitely changed in Camel regarding OSGi. I
haven't
figured out how to use Camel 2.4-SNAPSHOT in Karaf yet. Maybe you (or
someone else reading this) can help out?
When using Camel 2.3, I create my camel context using
the org.apache.camel.osgi.CamelContextFactory class. In runtime, this
class
is imported from the camel-spring-osgi bundle. The activator for this
bundle
(org.apache.camel.osgi.Activator) seems to reside in the camel-osgi
bundle
but that bundle also seems to be embedded in camel-spring-osgi. Have
to
admit that this solution is far from pretty but it seems to work. The
activator keeps track of installed bundles and their camel resources
(such
as components and languages).
When I switch to Camel 2.4-SNAPSHOT I get the following exception:
...
Caused by: org.apache.camel.ResolveEndpointFailedException: Failed to

due
to:
No language could be found for: file
at
org.apache.camel.impl.DefaultCamelContext.getEndpoint(DefaultCamelCon
text.java:377)
...
It seems like Camel cannot find the "file" language (which is
supposed
to
be
mapped to the org.apache.camel.language.simple.SimpleLanguage class).
I
then
tried to find the proper activator to find out why the language
doesn't
seem
to be registered.
First, the camel-spring-osgi bundle does not seem to exist in camel
anymore.
Instead, the CamelContextFactory is now imported from the
camel-spring
bundle. camel-spring's activator (org.apache.camel.osgi.Activator) is
now
part of the camel-spring component but when I look at it I can't see
that
it
keeps track of anything but it's own BundleContext and Bundle
instance.
Then
who keeps track of the registered components, type converters,
languages
and
so forth?
I must be missing something here. Can someone please explain to me
how
to
use Camel 2.4 in OSGi? I must say I've had a lot of problems with the
combination of camel and OSGi before as well but I was hoping for
Camel's
OSGi support to get better - right now I'm a bit disillusioned :-(
I noticed that camel-osgi still exists in Camel 2.4 but it doesn't
look
like
a bundle anymore. Maybe there is a secret here that I haven't fully
understood.

Claus,
I have now tested my version using both passive and active (which
requires a
certificate) mode. I've tested against a free ftp server -
Filezilla -
and a
commercial ftp server (that we often use) - Serv-u. It works fine.
I haven't tested your version yet because it requires me to build
my
application against Camel version 2.4-SNAPSHOT instead of Camel
version
2.3.0. To get this to work I need to get all the 2-4-SNAPSHOT
artifacts
into
my local Maven repository. I tried to do this by building Camel
locally
but
I never seem to get it to build. Right now, I'm stuck with the
following
Maven error message (I'm usng Maven 2.0.11):
You can just cd into camel-ftp and build that jar. And then you
grab
the camel-core jar as well.
And if you use spring then camel-spring .jar as well. Then you got
what you need for 2.4-SNAPSHOTs.
Yeah Maven can be strange. Sometimes you need to nuke you local m2
repo
cache.
And I use maven 2.0.9.

God you're fast. I made my own attempts and attached diff files to
the
JIRA
issue you created. I also added a couple of comments/suggestions to
the
issue.
In short I believe that it is probably easier for the
user/developer
if
it
is enough to specify whether a secure data channel should be used
or
not
(the default should be true). Adding more detailed options, like
you
did, is
of course just a benefit as long as it is possible to also
configure
it
the
easy way (like I described).
I haven't tested your changes yet - will do. I have done some
limited
testing with my own version, but only in passive mode. If you use
a
secure
data channel in active mode one must first create a public/private
key
pair
for the ftps client to use and I haven't gotten around to testing
that
yet.

I was one step ahead of you. I created the ticket and took a

Can you try with the latest source code? And maybe if there is
still
some issue then work on a patch from there.
Would be lovely with an unit test, but the test ftp server we use
cannot understand the secure data transfer.
Anyway would be awesome if you could test it on your real
systems.

And you may even want to contribute a patch :)

I'm using camel-ftp for secure ftps communication. I need to be

I have encountered problems using camel-ftp for ftps
communication
in
implicit mode.
Some ftps servers require that the file transfer is encrypted
(not
just
the
commands). This is of course very natural and is the reason why
ftps
is
chosen in the first place. However, commons-net (which camel-ftp
uses)
does
(for some reason) not by default setup a secure channel for
file
transfers.
It has to be requested by code similar to the following:
ftpsClient.execPBSZ(0);
ftpsClient.execPROT("P");
I suggest to add an option to camel-ftp, regarding ftps, to
make
it
possible
to specify whether the data channel will be encrypted or not.
Encrypted
should be default.
When looking at the code in camel-ftp it seems like there is no
special
handling during connect for ftps compared to ftp. Thus there is
no
natural
place to put the above code. One way is to add something like
the
following
at the end of the method "connect" in the class
"FtpOperations":
if(client instanceof FTPSClient) {
FTPSClient ftpsClient = (FTPSClient)client;
try {
if (useSecureDataChannel) { // useSecureDataChannel should
be
initialized from the configuration somehow
ftpsClient.execPBSZ(0);
ftpsClient.execPROT("P");
}
} catch (SSLException e) {
throw new
GenericFileOperationFailedException(client.getReplyCode(),
client.getReplyString(), e.getMessage(), e);
} catch (IOException e) {
throw new
GenericFileOperationFailedException(client.getReplyCode(),
client.getReplyString(), e.getMessage(), e);
}
}
Am I the only one having problems with this? Maybe there is a
workaround
that I haven't figured out.
