Could you tell me what specific problem are you getting with
tomcat installation? I am not a guru but may be I can help you out
with running simple blazeDS application.
If you have tomcat installed just put blazeds.war file into
/webapps directory, and while creating flex project check "use
remote object service " and select "Live Cycle Data Service"
Option. your server would be J2EE in case of tomcat. then you can
provide root Folder location pointing to blazeds installation
"C:\Apache\tomcat 5.5\webapps\blazeds" (my tomcat is installed in
this location). root url would be "
http://localhost:8080/blazeds".This would create project. then there are tutorial available to
configure different services. The simplest one for remoting is:
