Change the order in which bundles are deployed in JBOSS Fuse - apache-camel

Question

I'm deploying my apache-camel project in JBOSS Fuse as a feature. Following karaf feature file is used for the project.
<?xml version="1.0" encoding="UTF-8"?>
<features name="${project.artifactId}-${project.version}" xmlns="http://karaf.apache.org/xmlns/features/v1.0.0">
<feature name="${project.artifactId}" description="${project.description}" version="${project.version}">
...
<feature>camel-beanio</feature>
...
<bundle>mvn:${project.groupId}/abc-common/${common-version}</bundle>
<bundle>mvn:${project.groupId}/abc-service/${project.version}</bundle>
</feature>
</features>
When I install the main feature, it loads abc-service bundle before camel-beanio feature and the routes in abc-service which makes use of beanio dataformat fails.
I did some search on google and found options like, start-level, dependency, prerequesite ..etc. But, the currently configured name space is not permitting any of these attributes.
I also tried changing xml name space as provided in this example hosted on Github. But it was causing another error like
Caused by: java.lang.IllegalStateException: Could not find resource:
/org/apache/karaf/features/karaf-features-1.3.0.xsd
So, what could be rightway to ensure that camel-beanio feature is getting installed before actual service?

You should be able to write a feature file like this:
<features>
<feature name "nameOfYourProject">
<bundle dependency="true">mvn:org.apache.camel/camel-beanio/2.17.0</bundle>
..your abc bundle
..
</feature>
</features>
But I would probably advise you to create a folder called feature under /main and create a feature.xml. Manually edit that with your bundle dependencies such as:
<features>
<feature name="${project.artifactId}">
<bundle dependency="true">mvn:org.apache.camel/camel-core/2.17.0</bundle>
<bundle dependency="true">mvn:org.apache.camel/camel-blueprint/2.17.0</bundle>
<bundle dependency="true">mvn:org.apache.camel/camel-rabbitmq/2.17.0</bundle>
<bundle dependency="true">mvn:org.apache.camel/camel-jackson/2.17.0</bundle>
<bundle dependency="true">mvn:org.apache.commons/commons-lang3/3.4</bundle>
<bundle dependency="true">mvn:commons-codec/commons-codec/1.10</bundle>
<bundle dependency="true">wrap:mvn:org.apache.axis/axis/1.4</bundle>
<bundle dependency="true">wrap:mvn:org.apache.axis/axis-jaxrpc/1.4</bundle>
<bundle dependency="true">wrap:mvn:org.apache.axis/axis-saaj/1.4</bundle>
<bundle dependency="true">wrap:mvn:axis/axis-wsdl4j/1.5.1</bundle>
<bundle dependency="true">wrap:mvn:commons-discovery/commons-discovery/0.4</bundle>
<bundle dependency="true">wrap:mvn:javax.xml/jaxrpc-api/1.1</bundle>
<bundle dependency="true">mvn:org.slf4j/slf4j-api/1.7.13</bundle>
<bundle dependency="true">mvn:${project.groupId}/${project.artifactId}/${project.version}</bundle>
</feature>
</features>
Add this to your plugin section in your pom:
<!-- to generate the karaf feature file from feature template file -->
<plugin>
<groupId>org.apache.karaf.tooling</groupId>
<artifactId>karaf-maven-plugin</artifactId>
<version>4.0.2</version>
<configuration>
<aggregateFeatures>false</aggregateFeatures>
<includeTransitiveDependency>false</includeTransitiveDependency>
<addBundlesToPrimaryFeature>true</addBundlesToPrimaryFeature>
<addTransitiveFeatures>false</addTransitiveFeatures>
</configuration>
<executions>
<execution>
<id>plugin-feature</id>
<goals>
<goal>features-generate-descriptor</goal>
</goals>
</execution>
</executions>
</plugin>
Then when you run clean install the feature file will be generated in your target folder.
