症状

When adding a user, instead of going to http://localhost:8080/secure/admin/user/AddUser!default.jspa, users are redirected to http:///secure/admin/user/AddUser!default.jspa . The base URL is removed.

原因

The context path in server.xml has been set to be simply "/".

ソリューション

Change to context path to be either "/jira" (or any other path you prefer} or simply remove it all together:

<Context path="" docBase="$ /atlassianjira" reloadable="false">
