Hi Howard, But how do you debug your application ?
Oliver Adolph -----Urspr�ngliche Nachricht----- Von: Howard Miller [mailto:[EMAIL PROTECTED]] Gesendet: Dienstag, 24. Dezember 2002 10:30 An: Struts Users Mailing List Betreff: Re: Problems with Eclipse and Struts Hi, I use much the same set up as you and had lots of problems with those plugins. Personally I don't use them, I find it *much* easier just to keep a terminal/dos window open and use Ant to build and test the application. The Ant build script that is described in the Tomcat documentation (although it has a couple of mistakes!), gets the job done. I take the attitude that I always want to be able to modify and build my applications from the command line if I'm stuck and can't use the IDE.
