Hi,

A quick question, did you already install camel-jetty feature

features:install camel-jetty

Or do your customer bundle embed some camel jar? Or your customer bundle use different camel version with it used in FUSE ESB?

Currently I am using FuseESB 4.4 and Camel 2.8.1

I removed the default camel features that were installed with FuseESB 4.4, i think it was camel-2.7.2-fuse....

When I did an install of camel-jetty I executed the "features:install camel-jetty" command.

Hi,

To use Camel 2.8.1 in FUSE ESB 4.4 you need update lots of bundles and features, that's not a simple task, only remove the default camel features isn't enough.

Could you use the latest released FUSE ESB 4.4.1 which already use camel 2.8.x

Freeman

[jamie3_james.archibald]

I'll try the new service mix. Once this is deployed at the customers site, upgrading the ESB container might not be possible. In such a case is there documentation on how to upgrade camel in FuseESB?

[gingell_michael.gingell]

Still no luck. Upgraded to SMX 4.4.1 and now I am getting the same exception except now with the direct component.

I sent in a JIRA for this through our Fuse support subscription.

[njiang]

Can you check if there are other version of camel-core and camel-jetty whose are installed in your Fuse ESB.

Use the below command could help you to find them out.

  osgi:list |grep camel

[jamie3_james.archibald]

Looks like there were two instances of camel-core deployed.

2.8.0-fuse...

2.8.1

I uninstalled 2.8.0-fuse... and restarted my bundle and it worked!

I find this rather odd because I was able to successfully start other spring camel bundles with no problems. It seems this was the only bundle causing the grief.

Just a suggestion, would be good to perhaps put a warning (in SMX) when installing a bundle that may conflict with another bundle version.
