Different sessions between JSP and Servlets...
Okay, I have the following structure.
$CATLINA-HOME\webapps\a_subfolder\my_root\
Within my_root there are a number of subfolders that contain various
applications i.e. login, admin, reports and my WEB-INF.
The first thing I need to make sure of is that I am using the correct
terminology. Correct me if I'm wrong, but the structure I defined is a
<Context>, correct?
The problem I am having is that my JSP pages are receiving a different
session than my servlets. Because all of these applications exist within a
<Context>, I'm confused as to why the sessionIDs would be different.
My <Host> element is defined as follows (the only Context referenced is the
default).
<Host name="my_site.com" appBase="webapps\a_subfolder\my_root\">
<Context path="" docBase="\">
<ResourceLink name="jdbc/OracleDS" global="OracleDataSource"
type="javax.sql.DataSource"/>
</Context>
</Host>
I am obviously missing something important here, and could really use some
enlightenment (or a slap upside the head).
Thanks in advance!

That's suspicious in and of itself, but if I were you I'd start with a
clean install and make sure it works; then replace the default
Context in webapps (the directory named ROOT) with your own.

Thanks for the reply Hassan.
I definitely want this set up correctly, and I do intend to move the
<Context> elements out of the server.xml, but I have not been able to
successfully do so as none of the applications want to load from the
context.xml.

1) defining Contexts within server.xml is discouraged,
2) appBase and docBase must not be the same,
3) so, if you want to define your appBase as this:
<Host name="my_site.com" appBase="webapps\a_subfolder\"/>
:: create a META-INF/context.xml file within your Context with
<Context>
<ResourceLink name="jdbc/OracleDS"
global="OracleDataSource"
type="javax.sql.DataSource"/>
</Context>
NOTE: no path attribute and no docBase attribute should be used
in this case.

Thanks Christopher.
At this point, the context is coded within the server.xml. I understand that
the context should be placed within a context.xml file within a META-INF,
but doing so has been giving me problems thus far (something I plan to
tackle here shortly).
As for the JSP/Servlet session issues discussed within this thread, I
believe that I have them resolved.
Thanks once again for your valued input.
Best regards,
Mike

You should remove both of these attributes from your <Context> in
context.xml. As mentioned before in this thread, they are at best
ignored, and at worst confused by Tomcat or anyone looking at the file.

Hey Mark,
Your question as well as a previous post to another user in which you made
the point that the appBase should never point to a root directory helped me
resolve this and another JSP issue I was having. The change follows...
<Host name="my_site.com" appBase="webapps\a_subfolder\">
<Context path="" docBase="\my_root\">
I cannot thank you and Hassan enough for your assistance with this issue.
My very best regards,
Mike Cronin

The only <Context> I reference (whether right or wrong) is the default
Context shown above. As coded, all applications successfully load using the
default Context, but I'm not able to pass session variables between my
servlets and JSPs.

What values are you using for appBase and docBase?

I started from a clean install and continue to encounter the issue where my
JSP pages are not exposed to the session variables being set from within my
servlets. I believe that my <Host> element is set up correctly as I can get
to all of my site content as desired.
Have you experienced this? Your input is most appreciated.
