i have installed SUN APPLICATION SERVER 9.1. now the problem is when i want to add this server to NetBeans ide 6.1 it cannot recognise the installation directory and prompts me that the directory is invalid. please help.

Sorry i didn't know that .But anyways thanks for telling me the rules.it will not happen next time.

I recently brought Head First Servlets and JSP and i'm really happy by the way you people have designed it.It makes learning really simple.

I wish i had a Head First book on Jasper report Or iReport or SCJP.

If you have any information regarding it please inform.

Thanks once again for all the efforts you all put in.

This is first post since i am anew user!I will be highly gratefull to anybody who helps me.

i have been given a project using JSDK 1.6,NetBeans 5.5,MySql 5.0,JSTL 1.2.,Sun Application Server 9.1
At the end of every jsp page there is this tag--->
<jsp:include page="/includes/column_right_news.jsp" flush="true" />
<jsp:include page="/includes/footer.jsp" />

But both these two(column_right_news.jsp,footer.jsp) are missing from the entire project directory.Now when i try to delete or comment these tags error mentioned below is shown.The project is running fine if these are not deleted/commented.

HTTP Status 500 -
