Re: Re[4]: Quick Question
Hi, Alex.
Since JSP's are turned into servlets before they are executed, I don't
see why you couldn't do this. For your convenience, JSP's have some common
objects already available for use. The application object is equivalent to
the javax.servlet.ServletContext object you would get by doing a
getServletContext() call. So, application.getInitParameter(key) should do
the trick, too.

Hello TOMITA,
I know next to nothing about JSP. Haven't touched it. I use XMLC and
Barracuda to do presentation. However, I would think that you should
be able to use getServletContext() or something analogous in JSP.

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

TLC returned

TLC tomcats default directory is where ever you called the

TLC So if you dont use another script to call the startup.sh/bat file
TLC tomcats
TLC default will be the bin directory.
TLC Use this code to find the directory where WEB-INF is. Then you can
TLC traverse
TLC your directory structure from there.
