Can’t we write webapps in Eclipse
I would encourage you to write a webapp with a base Eclipse install. Notice how all the XML, JSP, XSD, Struts, JSF, Hibernate, etc. files are ALL editing via the Text Editor in Eclipse? Notice how you have to deploy the app manually using an Ant script? Notice how you cannot debug JSP pages? Notice how you can’t browse a database or generate Hibernate mapping files from the Database?
All of this and more is supported by MyEclipse. We build ontop of Eclipse to provide facilities specific to web application development.
