can't connect to the tamino server from tools under linux

Hi, i can’t connect to my tamino server per http://localhost/tamino from the tools(x-plorer, schema editor etc.). In the dialogwindow, when i click the select button, i become a message " no list of databases avaiable", although all of the databases are running. --I can start my tamino server with http://localhost:9991/smh/login.htm, everything works well --the tools and the server are installed in the same location I don’t know what’s wrong. Help! chacha
