Aled Sage created BROOKLYN-338:
----------------------------------
Summary: brooklyn-rest-client feature fails when used it in Karaf
Key: BROOKLYN-338
URL: https://issues.apache.org/jira/browse/BROOKLYN-338
Project: Brooklyn
Issue Type: Bug
Reporter: Aled Sage
Running in Karaf with 0.10.0-SNAPSHOT, I was trying to use a Java-based entity that depended on brooklyn-rest-client. Unfortunately it gave the error below when trying to call {{BrooklynApi.getServerApi}}:

Fixed the immediate error by adding to {{brooklyn-rest-client/pom.xml}}:
{noformat}
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<version>2.5.3</version>
<extensions>true</extensions>
<configuration>
<instructions>
<Import-Package>*,org.jboss.resteasy.client.core.marshallers</Import-Package>
</instructions>
</configuration>
</plugin>
{noformat}
Note the absence of version in the import. Because it is built with pax wrap ({{wrap:mvn:org.jboss.resteasy/resteasy-jaxrs/${resteasy.version}}}) it gets version {{0}}. So got a wiring error.
When giving it an explicit version number (with {{wrap:mvn:org.jboss.resteasy/resteasy-jaxrs/${resteasy.version}$Bundle-Version=${resteasy.version}}}), that seemingly just gave the bundle the version number and not the Export-Packages, so still got the same wiring error.
Hence backing off from giving any version number requirement in the Import-Package.

The normal reason for this (e.g. http://stackoverflow.com/questions/14775572/unable-to-find-a-messagebodyreader-of-content-type-application-json) is that RESTEasy Jackson provider is missing from the classpath.
Indeed, looking at {{bundle:list -s -t 0 | grep -i resteasy}}, it showed that the only resteasy bundle was {{wrap_file__Users_aled_repos_cloudsoft_amp_karaf_cloudsoft-amp_target_assembly_system_org_jboss_resteasy_resteasy-jaxrs_3.0.8.Final_resteasy-jaxrs-3.0.8.Final.jar}}.
It probably missed the others out because they were considered "optional".

Tried removing {{dependency="true"}} from each bundle in the brooklyn-rest-client feature (as defined in brooklyn).
This forced it try to add all those bundles, but led to the error below:

At this point, when it needs yet another different version of guava (between {{[15.0.0, 15.1)}}), things are getting depressing!
---
The long-term solution is probably to refactor brooklyn-rest-client: to have it just depend on {{javax.ws.rs}}, and then the user of the feature gets to choose the impl (where we test with cxf).
The short-term solution for my problem was to abandon using brooklyn-rest-client in my Java entity, and to instead use a combination of Brooklyn's HttpTool and fasterxml.jackson ObjectMapper.
