Hi, the problem is, that tomcat7 don't use the proxy. The tomcat6 use this option on the same server...
tomcat7/javaopts: -Djava.awt.headless=true -Xmx4096m -XX:+UseConcMarkSweepGC -XX:MaxPermSize=1024m -XX:+UseParNewGC -XX:MaxNewSize=512m -XX:NewSize=512m -XX:SurvivorRatio=128 -XX:MaxTenuringThreshold=0 -XX:+UseTLAB -XX:+CMSClassUnloadingEnabled -Dhttp.proxySet=true -Dhttp.proxyHost=10.xxx.xx.xx -Dhttp.proxyPort=3128 -Dhttps.proxyHost=10.xxx.xx.xx -Dhttps.proxyPort=3128 -Dhttp.nonProxyHosts=*.domain.local Tomcat Applications can't connect services over the proxy on Dhttp.proxyHost on Dhttp.proxyPort regards Karsten
