Hi ,
the tcl_to_oracle_list proc is inside the utils-extra.tcl file which you have to put inside your servers /web/server0/tcl dir (utils-extra.tcl is not included in a standart oacs instalation, I think I should replace it with a call to join ).
Their is a jabber-drop.tcl, I upload a tarball including the jabber-drop.tcl and the latest bugfixes to the file storage, later today (I dont have access to cvs).
