nginx - Tomcat multiple domains Jelastic tutorial -

i've tried follow jelastic 'multiple domains' tutorial, got no success.

http://docs.jelastic.com/multiple-domains2 

i deployed 2 applications different contexts, mapped cname in dns record, edited server.xml , added host entries. i'm getting error when trying access:

502 bad gateway nginx/1.4.0 

here server.xml entries:

  <host name="urbanistico.com.br" appbase="webapps/urbanistico" autodeploy="true">     <alias>urbanistico.com.br</alias>     <context path="" docbase="${catalina.base}/webapps/urbanistico" />   </host>    <host name="smarttrade.com.br" appbase="webapps/st" autodeploy="true">     <alias>smarttrade.com.br</alias>     <context path="" docbase="${catalina.base}/webapps/st" />   </host> 

the applications deployed as:

 webapps/urbanistico  webapps/st
