My company would like me to manage Alfresco project though I don't have experience in Linux,Alfresco and Tomcat. I installed Alfresco 4.2c in Ubuntu server. Everything looks working fine except "Edit Online" button so far. Sharepoint has been configured. I can test it by opening a word document which is from Alfresco Repository using office Word. I can edit and save the changes. However, When I tried to click button "Edit Online", nothing happened. I did the following things according to my search, nothing works. I have tested in Wondows 7 + office 2003 and Windows 7 + office 2010
