I am trying to install “SOA and Data Services Tooling” and “Business Rules Tooling” on Getting error at JBoss Central but whenever I try to put any text in the Find bar and click refresh I get the following error:

"Failed to discover all connectors.

See 'Details' for more information"

Failed to discover all connectors.

RemoteBundleDiscoveryStrategy failed with an error

When clicked OK got the following message:
