XPage Gotcha #2: Ports
Thursday, December 17, 2009 at 4:41PM Two months ago I blogged about a potential gotcha for deploying XPages based on the fact that many XPages need to run Restricted Operations. It turns out there can be a few more issues for those of you who operate in environments in which tight reigns are placed on network communictions....
Some time back I encountered a series of issues trying to load the new eclipse Domino Help. The solution turned out to be to edit the proxy settings in the Location document to allow traffic to localhost:2765.
After updrading to Notes 8.5.1 in this same environment it was also proving to be impossible to run Xpages inside the Notes client. After investigating this issue it was discovered that XPages runs inside the Notes client by running a Web server on the local machine (even for XPages hosted on a Domino server). The URL for the Xpage was 127.0.0.1 but the port number assigned seems to be different for each and every Notes session. In essence it becomes to necessary unblock 127.0.0.1:* in order to get the XPage to display in my Notes 8.5.1 client.
