Question about features list

[sudhirshakya]

Hi,

I am a newbie to Fuse ESB, just installed ESB and trying to run it. I am using ESB 4.0.0.4 and all the cfg files that came with the installation.

While running the command 'features list', I got the following error

servicemix> features list

  State          Version       Name

ERROR UnknownHostException: svn.apache.org

I checked and found that I had lost the internet connection at that time.

Was servicemix trying to connect to svn.apache.org? And if so, why would it do that?

I fixed the network and everything worked fine.

Thanks

If you have installed Fues ESB 4.0.0.4 version, then a list of preconfigured repositories will be in your etc/org.apache.servicemix.features.cfg file, i.e.

featuresRepositories=http://svn.apache.org/repos/asf/servicemix/smx4/obr-repo/features.xml,mvn:org.apache.servicemix.nmr/apache-servicemix-nmr/1.0.0.4-fuse/xml/features,mvn:org.apache.servicemix.features/apache-servicemix/4.0.0.4-fuse/xml/features

By default, it will go over to intenet to download the feature xml files according to the repo list in the configure file. If your internet connection is down, then it will throw an exception of "ERROR UnknownHostException: svn.apache.org". Note, the first reposity in the list is "http://svn.apache.org/repos/asf..." and that was why you got UnknownHostException of "svn.apache.org".

With the internet connection still down, if you do the command "features list" the second time, it will work. The reason is that Maven will blacklist the repository and go to other local repositories instead. In this instace, it will go to your "fuse-esb-4.0.0.4\system" directory because your etc\org.ops4j.pax.url.mvn.cfg file defines your local maven repo as:

org.ops4j.pax.url.mvn.localRepository=file:${servicemix.home}/system@snapshots

Note, the Fuse ESB 4.0.0.4 is shipped with all the relevant libraries in the "system" directory including Fuse ESB 4.0.0.4 feature xml file and nmr feature xml file. It means that even without internet connection, it will work the second time.
