Can I use something like this in my jsp page (instead of a java sevlet) to
get the parameter name?,
before that I set the parameter in my web.xml file like this:
<context-param>
<param-name>parameter name</param-name>
<param-value>localhost</param-value>
</context-param>
String value = getServletContext().getInitParameter("parameter name");
because I'm confusing here because of the name "getServletContext"..... is
it only works in a sevlet or it will work too in a jsp page???
thanks again

Hello TOMITA,
Where does your Bean exist? Is it in one of Tomcat's classloaders, or
is it running out the WEB-INF/classes or WEB-INF/lib folder of your
webapp. I'm geussing the it is in one of Tomcat's classloaders
meaning $CATALINA_HOME/common/lib, server/lib, or lib (shared/lib in
Tomcat-4.1.x).
Those classloaders can't see the individual webapp classloaders.
However, libraries in your webapp *can* see Tomcat's plublic
classloaders (all bug server/lib, server/classes).
You may have to rearrange the location of your libraries.
