Default A question on bookstore sample app and pointbase
Hi all:

This is regarding the bookstore sample program bundled in the webapps folder of the Java System Application Server PE-8. The problem I face is this:

The admin console lists the appname and context roots as bookstore1. Hence the logical pathname should be http://<localhost>:<port>/bookstore1/ . However, this does not work, and I need to type /enter at the end to make it work. What is going on?

I start the application as instructed and go through one shopping cycle, and check out. I am once again instructed to "Continue Shopping", but upon clicking the "Continue Shopping" link, I get a error page saying that the servlet is unavailable. The log stack trace is as follows:



Servlet.service() for servlet BookDetailsServlet threw exception

Please help me with what is going on? Am I missing some settings, or is there a bug in the release I am unaware of? Are there any fixes?

Moreover, are there any alternatives to the pointbase database server bundled with SAS PE-8? Could I use MS-Access2k, for ex. and how do I configure it to work with these sample apps? I am really uncomfortable working with pointbase.
