I tried to add bean into blueprint.
Added CXF namespace. But, JBOSS FUSE shows
13:10:28,339 | INFO | NAPSHOT-thread-1 | BlueprintContainerImpl | 14 - org.apache.aries.blueprint.core - 1.0.1.redhat-60024 | Bundle camel-basic is waiting for namespace handlers [http://camel.apache.org/schema/cxf]
So, I remove the cxf and added blueprint namespace
http://camel.apache.org/schema/blueprint/cxf http://camel.apache.org/schema/blueprint/cxf/camel-cxf.xsd
But, still no use, It shows same error for this namespace also.
Do I need to change anything in pom, blueprint.xml r need install anything in jboss fuse?
I have no clue about this.

I haven't used this bean in any place. First I need to resolve this problem then I need to use it in route.
I check the
Please help me.
Install all needed features into your Fuse container (see here for more information):
features:addUrl mvn:org.apache.camel.karaf/apache-camel/2.9.0/xml/features
features:install war
features:install cxf
features:install camel-jaxb
features:install camel-blueprint
features:install camel-cxf
Well, I went through all the steps stated above to find out it still does not work in blueprint.
Strangely as soon as the route was dropped in the spring xml and taken out of blueprint everything started working like a magic.
Tried camel-cxf instead cxf and worked with blueprint

I have one jar file (connection.jar) which is an OSGI bundle with folder structure src/main/resources/META-INF/spring/mq-connect.xml
following connectivity code is placed in the mq-connect.xml

I have another osgi bundle (connection_impl.jar) which contains camel routes. I want to use "amqtx" bean as the component in the camel endpoint.
Following is the code which I put in the camel-context.xml to access the "amqtx"
<beans ...... >
<import resource="classpath*:mq-connect.xml"/>
...

<camelContext trace="true" streamCache="true" autoStartup="true" xmlns="http://camel.apache.org/schema/spring">

I am using jboss-a-mq-6.2.1 and deploying to Karaf container. OSGi bundle connection.jar deploys successfully but connection_impl fails to deploy.
It gives following error in the A-MQ logs
Stack Trace:
org.apache.camel.RuntimeCamelException: org.apache.camel.FailedToCreateRouteException: Failed to create route TEST_AMQ:
Route(TEST_AMQ)[[From[amqtx:INBOUND.QUEUE]] -> ... because of Failed to resolve endpoint: amqtx://INBOUND.QUEUE due to: No component found with scheme: amqtx
I tried the part in various ways but still amqtx is not accessible in another bundle.
Please suggest any missing import,export/wrong configuration so that amqtx component in connection.jar is accessible in connection_impl.jar
Not sure if you can make this work at all but it is definitely not recommended to import a spring xml in another bundle.
Better export the bean as a service in the first bundle and refer it as a service in the second. This will also decouple your bundle in a better way.
I am in agreement with Christian. When you are using OSGI bundles are typically isolated unless you explicitly set exports for a library another bundle uses or you are exposing an OSGI Service. If you would like to setup an OSGI service my recommendation is doing it the Spring Framework way since its relatively clean. You can expose your Component via an interface. I'll show an example below.
Typically I like to have 3 bundles managing this. I usually have a bundle that contains just the interface that I will be exposing between separate bundles. A Bundle that is the implementation of the interface and a bundle that leverages the interface's injected implementation to accomplish a task.
//Interface bundle will expose an Interface and any Pojos associated. Ex:
public interface AlternateFacilityApi {
public String getAlternateFacility(String facilityName);
}
//Implementation bundle will register an OSGI service based off of the implementation bean from your interface (yes the previous bundle is a dependency OSGI wires in)
public Class MyAlternateFacilityImpl implements AlternateFacilityApi {
public String getAlternateFacility(String facilityName) {
return "Bob's house";
}

I'm having problems re-deployin a JAR on Servicemix (5.5.1) using Blueprint, Camel and Camel-CXF:
org.apache.aries.blueprint.core - 1.4.3 | Bundle my-camel-project is waiting

Aparently, certains URLs has been modified today:
http://camel.apache.org/schema/blueprint/cxf -> Not found
http://camel.apache.org/schema/blueprint -> Index of /schema/blueprint
This is a part of my blueprint definition:

I builded this codes following a lot of examples on Camel tutorials and Camel In Action book. Was working some days, but not right now.
There are something new recently?
I know I can define Camel routes in stand-alone xml file, using the Blueprint syntax. If I move one of this file in the "deploy" folder of ServiceMix, it automatically becomes an OSGI bundle. My question is, can I set an endpoint to this new bundle, accessible from outside?
I would like to do something like this:
blue_route1.xml
<blueprint>
<camelContext>
<route>
<from uri="http:my_servicemix:8181/blue_route1_endpoint" />
<to uri="jetty:http://server1" />
</route>
</camelContext>
</blueprint>
blue_route1 becomes an OSGI bundle once deployed, but where should I define "blue_route1_endpoint" ? Is it doable?
[UPDATE]
summering, I want that an external WS is able to send messages to blue_route1_endpoint, where the blue_route1 bundle will redirect messages according to Camel routes, without the need to create a new WS "Blue_route1" to deploy in ServiceMix
______________________
| ____________ |
external-->(blue_route1_endpoint)==|==-->|blue_route1|--|-->(http://server1)
WS | |___________| |
|____________________|
ServiceMix
Found it! I didn't get that it's so easy. To make ServiceMix listen on a port, I just have to specify the endpoint using the Camel-jetty component.
So, to answer my question, I solved in this way:
install the camel-jetty component in ServiceMix
features:install camel-jetty
Write the camel-route with Blueprint, in blue_route1.xml file
<?xml version="1.0" encoding="UTF-8"?>
<blueprint
xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<setHeader headerName="Content-Type">
<groovy>"text/xml; charset=utf-8"</groovy>
</setHeader>
<to uri="http://server1"/>
</route>
</camelContext>
</blueprint>
I used a random port 8181 to listen to... but I could choose every number, ServiceMix will automatically start a jetty component, listening and consuming on that port/endpoint.
For SOAP messages you need CXF Component and wsdl file of your webservice. You can configure your endpoint outside of the camelContext like this:
<cxf:cxfEndpoint id="yourId" address="/your/address/to/endpoint"
serviceClass="your.java.ServiceClass"
wsdlURL="path/to/your/wsdl/file.wsdl" />
And in your route use tag like this:
<from uri="cxf:bean:yourId"/>
You need to add namespace and schemaLocation to your blueprint to use cxf namespace, use this:
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:cxf="http://camel.apache.org/schema/blueprint/cxf"

I am trying to get a CXF endpoint working on Servicemix 4. I have created a Spring archetype with a CXF endpoint and successfully installed it with Maven. Having run osgi:install - s mvn: it installs onto Servicemix but the logs are displaying:
Application context refresh failed (OsgiBundleXmlApplicationContext(bundle=springdm,
config=osgibundle:/META-INF/spring/*.xml))

I have built this route just on Camel before with the following in my context.xml file:

</route>
</camelContext>
This is a clone of a working Camel context file but I cannot see why ServiceMix is throwing the error when it starts. The only difference is that the pom file does not use CXF as a dependency but it is in the section which I took from the online example.
I would be grateful for any pointers for any missing imports or corrections to the context file or anything that I ought to check for.
Many thanks.
Shortly after posting, I discovered that I was missing the camel-cxf dependency in my POM file which causes this error. I also needed to make sure that it was the right version as this caused an error in ServiceMix finding the correct META.cxf file.
I try to set up a camel (Ver. 2.4.0) route in a FUSE (Ver. 4.3.0) ESB/OSGi container.
It should be a simple cxf-proxy to route a WebService call from a 'proxy' address to a real service.
I read several documentation:

Trying to start the bundle in FUSE leads to this exception

I do not know what's wrong. I doubt that my Endpoint address is wrong and I do not know what my servlet address is (there is no cxf:cxfEndoint servelt address attribute).
Any help to lead me in the right direction to solve this problem would be appreciated.
Thanks

I finally found out what's wrong.
Instead
<!-- the proxy service -->
<cxf:cxfEndpoint
id="myServiceProxy"
address="http://localhost:9003/cxf/myService"
serviceClass="foo.bar.iface.MyServiceInterface" />
it has to be
<!-- the proxy service -->
<cxf:cxfEndpoint
id="myServiceProxy"
address="/myService"
serviceClass="foo.bar.iface.MyServiceInterface" />
As the first approach worked well running the camel project outside FUSE (in this case a the http server will be started to provide the service) it has to be a relative address inside FUSE.
Inside FUSE the embedded HTTP server which runs on (localhost:8181) will be used and the service url will be extended to http://localhost:8181/cxf/myService.
