----------------------------------
Summary: Knox upgarde from pre-1.0.0 fails because of error
"unable to compile class for redirecting.jsp"
Key: KNOX-1371
URL: https://issues.apache.org/jira/browse/KNOX-1371
Project: Apache Knox
Issue Type: Bug
Reporter: Sandeep More
Assignee: Sandeep More
Fix For: 1.1.0
When upgrading Knox, the JSP files are not upgraded and the packages they
reference are not part of the adapter package, as a result we get the following
error in gateway.log after upgrading
{code:java}
