I have downloaded Juno for Java EE and I am trying to get it set up with JBoss AS integration.

Methods I have tried...
1.
I go to servers window -~> new server -> adapters -> where JBoss AS used to be in indigo, it is no longer.

2.
Juno -> Help -> Eclipse MarketPlace -> 'JBoss' -> JBoss Developer Studio (Juno) -> Install -> Error -> Unable to read repository at https://devstudio.jboss.com/updates/6.0-staging/content.xml.
sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

3.
Juno -> Help -> Eclipse MarketPlace -> 'JBoss' -> JBoss Tools (Juno) -> Install -> Unable to read repository at http://download.jboss.org/jbosstools/updates/development/juno.
http://download.jboss.org/jbosstools/updates/development/juno is not a valid repository location.

4.
Get update site for JBoss Developer Studio (Juno) from MarketPlace directly and try 'install new software' -> same site as method 2, same error

5.
Get update site for JBoss Tools (Juno) from MarketPlace directly and try 'install new software' -> same site as method 3, same error

6.
JBoss Community -> Can't install JBoss AS Server adapters from Juno JavaEE M3 -> Nick Boldt's Solution -> http://download.eclipse.org/webtools/downloads/drops/R3.4.0/I-3.4.0-20120426145544/repository/ -> Error -> Could not find http://download.eclipse.org/webtools/downloads/drops/R3.4.0/I-3.4.0-20120426145544/repository/

7.
community -> https://community.jboss.org/message/754415 -> points to same as method 6.

8.
stackoverflow -> http://stackoverflow.com/questions/11982718/how-to-deploy-on-jboss-as-7-from-eclipse-juno -> Solution: http://download.jboss.org/jbosstools/updates/nightly/core/trunk/ -> Error -> Unable to read repository at http://download.jboss.org/jbosstools/updates/nightly/core/trunk/.
Unable to read repository at http://download.jboss.org/jbosstools/updates/nightly/core/trunk/.

Can someone please help with this issue. It appears to be leading me in circles... Can Juno work with JBoss?

Thank you all in advance
