But so far nothing. So I refer to his blog. It has a link to a blueprint.xml file. Which refers to Java routes, which are defined as <bean>. The blueprint.xml file is then placed in the META-INF/blueprint directory. The standard place for that. Then Karaf + Camel takes care of handling the lifcycle and Camel knows its running in OSGi, and its using the Blueprint CamelContext and so forth. And in Camel 2.10 you can unit test blueprint outside Karaf http://davsclaus.blogspot.se/2012/01/unit-testing-osgi-blueprint-with-apache.html > Cheers, > Borut > > >> >> >> > Thanks, >> > borut >> > >> > Dne 11. april 2012 09:05 je Claus Ibsen <claus.ib...@gmail.com> >> napisal/-a: >> > >> >> On Wed, Apr 11, 2012 at 8:32 AM, Borut Bolčina <borut.bolc...@gmail.com >> > >> >> wrote: >> >> > So instead of >> >> > >> >> > <dependency> >> >> > <groupId>org.apache.camel</groupId> >> >> > <artifactId>camel-core</artifactId> >> >> > <version>${camel-version}</version> >> >> > </dependency> >> >> > >> >> > I use camel-core-osgi and use the OsgiDefaultCamelContext instead and >> I >> >> > should be safe? >> >> > >> >> > public void start(BundleContext context) throws Exception { >> >> > camelContext = new OsgiDefaultCamelContext(context); >> >> > ... >> >> > } >> >> > >> >> >> >> Yeah try that. >> >> >> >> > Will this enable me to use Camel commands in Karaf or will I have to >> use >> >> > osgi:start command? >> >> > >> >> >> >> You need to install the Camel Karaf commands, they come out of the box >> >> if you install the camel feature. >> >> >> >> In Karaf 2.2.6 onwards its even easier to install Camel as you dont >> >> have to remember a mvn url, as there is a new chooseurl command. >> >> The name of that command IMHO could have been better, as now you have >> >> features:addUrl and features:chooseUrl, and they kinda does the same. >> >> >> >> Anyway its something a like: >> >> >> >> features:chooseurl camel 2.9.1 >> >> features:install camel >> >> >> >> See details here >> >> http://camel.apache.org/karaf.html >> >> >> >> >> >> if you use CXF in Karaf then there is a jre properties file you need >> >> to replace.
