I was using IntelliJ since the version 4.5 and I found that it is very annoying to continuously restart server when some class or JSP page was changed. By some reasons InteeliJ does not do the same what eclipse does in this case - redeploy resource on server. I am currently using IntelliJ 7.03 and Tomcat 5.0. May be there is some magic word that I should say in order to force InteeliJ redeploy at least JSP pages, but redeploying classes would be also cool.
On my Work use RAD6 and WebSphere 6.0. Once some java file or JSP page is changed then it immediately redeployed. But IntelliJ does not do the same.
