I need to be able to run Tomcat applications from Document Root to access them as www.domainname.com/index.jsp?
ResolutionFirstly, you should deploy an application with Plesk then edit the 'path' value for the appropriate application in tomcat4/conf/server.xml:
Additionally, you should create domainname.tld/conf/vhost.conf and add:
WebAppConnection domain_tld_Connection1 warp Server_IP_address:9008
WebAppDeploy "yourapps.war" domain_tld_Connection1 "/"
next, you should rebuild the apache configuration files with:
# /usr/local/psa/admin/sbin/websrvmng -a -v
and restart tomcat.
Now you can access your application with domain.tld path in browser.
