Hi I try to do it only simple project using simple servlet. When I created Dynamic Web Project and added simple servlet to project I received something like this: Project SimpleProject2 is missing required library: '/local/jboss-4.2.0.CR2/server/default/lib/javax.servlet.jsp.jar' What should I do ?? because I have in /local/jboss-4.2.0.CR2/server/default/lib/ package with 'jsp' but name of this package is diffrent -> jsp-api.jar. I try to change name of this package to jsp.jar but error is still. What should I do in order to my application to run. I spent a lot of time in this forum but I didn't find solution of this problem. Environment: Eclipse 3.2.2 JBoss-4.2.0.CR2 JBossIDE-2.0.0.Beta2-ALL for Eclipse. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4053114#...
