I have been trying my head around the camel NMR component and wanted to practice some of use cases on servicemix platform. But to my surprise, I could not find the nmr feature in servicemix 5.3 version which I have.
Is support for NMR in servicemix withdrawn? Please help me understand this.
Yes JBI support in ServiceMix 5.x is dropped. JBI is dead, do not use that.
The NMR component was part of JBI and hence dropped.
Just use pure Camel in ServiceMix.

NMR is not available but we can use direct-vm component which is working same as NMR.

I wonder if it is possible to integrate an old version of a Camel component, with an application of a newer Apache Camel version. In my case I want to integrate to Hbase server version 1.2, that is supported only with HBase client 1.2. Therefore even though I want to use a 3.1 Camel version, I want to use the 3.0.1 version of Camel-HBase component. Is it a fine thing to do?
Or is there any place that I can see the versions of the libraries Apache Camel supports?
You can check the Camel dependencies POM to find the versions of dependencies that are imported by the different components.
See the dependencies POM of Camel 3.10.x. You will find <hbase-version>2.3.1</hbase-version> in it.
Another source is Maven Central where you can see the dependency versions of a specific Camel component version.
See Camel-HBase 3.1.0 that references Hbase-client 1.2.6.
However, normally one cannot choose the Camel version to match a specific component dependency version. In general it is the other way round. You want or have to work with an already existing version or you want to use a current version to get the best of the framework.
If you build a new application with Camel 3.10.x, you get the hbase-client in version 2.3.1.
If newer Hbase client versions are not compatible with Hbase 1.2 it becomes difficult.
you get lots of problems when you mix and match Camel component versions
even if you can build your application with an older Camel version, you could never upgrade
The only solution I see would be to isolate the Hbase integration in its own (freezed) application with an older Camel version that matches your desired Hbase-client version.
I am setting osgi-bluprint and apache camle project and I am wondering how we can integrate this two compoenent.
There are plenty of examples out of the box with Apache Camel.
See the OSGi / blueprint examples at:
https://github.com/apache/camel/tree/camel-2.x/examples#welcome-to-the-apache-camel-examples
This could be a good place to start.
http://camel.apache.org/using-osgi-blueprint-with-camel.html
It is a very common pattern to use OSGi-blueprint and Camel (with OSGi runtimes such as Apache Karaf) and there are plenty of examples out there.
What is the difference between Apache camel-jbpm and jboss jbpm ?
Since Apache camel(2.16.3) is having one component as camel-jbpm.
I am confused which one I should use ? I am integrating with karaf. please suggest.
JBoss BPM (business process - a.k.a human workflow) is a project you can find and read more about here:
http://www.jbpm.org/
Apache Camel is an integration library that allows to integrate with a lot of different system. Doing so by using Camel components. One of these components is camel-jbpm that makes it possible/easier to use JBPM from Camel users.
http://camel.apache.org/jbpm
So if you have an existing BPM system and need to integrate with that from a Camel application or Java application, then using the camel-jpmn can make that (much) easier.
Hi I would like to know which camel version is used in Fuse esb (jboss-fuse-6.0.0.redhat-024),
according to the migration guide it's 2.10.0 .
how can I update it to use 2.10.5 ?
JBoss fuse is using customer version of Camel which is based on the Camel 2.10.x branch.
As there are lots other projects which may relates to this Camel version, I don't suggest you to change the version yourself.
I am new to serviceMix, I downloaded serviceMix 4.5.1 a couple of days ago.
When I tried to install ode in serviceMix using the command
features:install ode
It tells me this:
Error executing command: No feature named 'ode' with version '0.0.0' available
I googled/baidued mass of webs, I got a bad news that:
"Fuse ESB 4.4 does not support Apache ODE. The latest version of ODE is not compatible with Fuse ESB."
which comes from
http://fusesource.com/forums/thread.jspa?messageID=11209
Fuse ESB - ODE installation
So if serviceMix 4.4 does not support ODE any longer, what is the alternative way to do the web service orchestration in serviceMix? I have tried use camel to do this work,but that's not easy.
How about "bpel-g"?(http://code.google.com/p/bpel-g/) is it a good choice? or any other choice?
Any help will be really appreciated.
I like Activiti for processes and orchestration.
Never run it inside Karaf/SMX/Fuse ESB but it should be possible, if not using this instruction.
It also has a nice web explorer for human tasks etc. if you need it and BPMN modeller for rapid desing and visualization
I would recommend to try bpel-g. A colleague and me have been doing some BPEL conformance benchmarking lately (fyi: the benchmarking tool is available at github) and bpel-g turned out have the highest degree of support for the BPEL spec., along with the older ActiveBPEL engine from which bpel-g is a fork. ODE ranked third place.
Another nice feature of bpel-g is that it is indeed actively maintained. I don't know how well it integrates into the infrastructure of Fuse ESB, but since it's deployable as a war, this shouldn't be much of a problem.
UPDATE: Just had a look up: bpel-g seems to integrate with camel and provides a custom handler to invoke camel components. So, basically, the solution outlined in Petters answer also applies to bpel-g and, in contrast to Activiti, it has a message correlation framework. Finally, the barrier to using it should be smaller, as you already know BPEL. As a consequence, bpel-g might be a more suitable solution here.
