Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Download and install the "Drools JBoss Rules 5.0" source code for
   the sampleApplication
2. Bring up the web application: Add a customer, Fill out a loan request,
check the task list.
3. Click on the "Approve Event" link.

What is the expected output? What do you see instead?
Expected is a refresh of the "customerList.htm" page.  Instead:

HTTP Status 500 -

type Exception report

What version of the product are you using? On what operating system?
Download as of 2 Dec 2009.  Linux OS Fedora 11.  I had to insert a
"?sessionId=1" to the end of the "approveEvent.htm" entry on the
CustomerList.jsp source code.

Please provide any additional information below.
Thanks for the book.  It is an essential guide to Drools and a lot of other
technology that is useful.

Hi,

Thanks for reporting this. As you've correctly found out you need to pass a 
sessionId 
parameter to the approveEvent.html

Please see the book for more details.
