sorry for late reply!
Why don't you go for netbeans, you just need to code and then it will do everything for you, like creating war file, ear file e.t.c
For the application server in dreamweaver i never tried it, but just start the default server, then on remote testing just put your URL like http://localhost:8080/JspFile, but bear in mind where the testing server location is, the folder. I used Tomcat, you can follow the instruction as follows: www.gurnah.com/blog
Hope you find you answer
from dream viewer menu select
site -> New
enter the name of the site not url
enter url of the server like folowing(how u r invoking files in the browser)
http://localhost:8080/abc/
next yes server technology select JSP
then select edit and test locally
and browse the root folder
like this
C:\Tomcat\webapps\abc\
in next page again give the url like this
http://localhost:8080/abc/
then click test url button.
i think it will help you
i tested this method with dream viewer 8.
please change your url according to your web application
thank you
