RE: JDBC Connection over VPN
Could the VPN connection be utlizing the same port Tomcat or Oracle usually does? Like something at 8080? Not sure if that's the case; or conversely, does going into VPN block those ports? -Original Message- From: Sanjeev Sharma [mailto:sanjeev.sha...@buchanan-edwards.com] Sent: Monday, May 07, 2012 2:36 PM To: Tomcat Users List Subject: JDBC Connection over VPN Hi, Not sure if this is a Tomcat issue. When I connect directly to a network and startup my tomcat 7, my JDBC connection to an Oracle 11g network works just fine, but if I tunnel into the same network, JDBC fails to connect to the database. At the same time I'm able to make a connection to the same database using SQL Developer/SQL Plus. My network people tell me that all ports are open to me and when they try to capture packets coming from me, they see nothing if I'm starting up my tomcat. I'm not a Network or VPN expert, but as far as I know, at the application level it should behave just as if I'm connected directly to the network and shouldn't have to worry about which network adapter to use (built in or VPN), and shouldn't have to worry about routing. I'm at a complete loss, so I'm just hoping there is magical tomcat setting which will fix my problem. Any help would be appreciated .

Can you run telnet DatahbaseIpaddress 1521 from command prompt when you VPN into your network?

RE: JDBC Connection over VPN
Found a solutions for this. Apparently Java 7 wraps IPV4 addresses as IPV6, which is not supported by Cisco Anyconnect. Turning of IPV6 on the Cisco VPN adapter (Control Panel\Network and Internet\Network Connections) fixed the problem. -Original Message- From: Sanjeev Sharma [mailto:sanjeev.sha...@buchanan-edwards.com] Sent: Monday, May 07, 2012 4:04 PM To: Tomcat Users List Subject: RE: JDBC Connection over VPN Telnet seems to connect. -Original Message- From: Saurabh Makol [mailto:saurabh.ma...@gmail.com] Sent: Monday, May 07, 2012 3:50 PM To: Tomcat Users List Subject: Re: JDBC Connection over VPN Can you run telnet DatahbaseIpaddress 1521 from command prompt when you VPN into your network?
