INFO: Marking servlet jsp as unavailable
Hello,
well I have the following problem:
I use kornak-api which provides a simple servlet-based recommender
application available under the Apache license.
Wenn I want to start the webservice I get the following error:

but I don't know how to fix this. Does anyone know this error and how
to fix this? I try it the last 2 days but I can't fix it. :( I tried
so much things but without success... :(
I will be happy about every help. :)
Greetings, Clodan

1. Do not top-post
2. That server where it fails is your system. We do not have access to
it and we do not know anything about its actual configuration.

Hello,
thanks for your reply.
But I don't think that this is the solution. I could make this on my
system without errors. Then I installed a virtual machine (Vagrant)
and in this machine it isn't working. I have everything installed,
Path's and Codes are the same. Do you have any idea why it work on my
system but not in my virtual machine (Vagrant)? It is the same OS as
well.

The servlet was marked as unavailable because it failed to
initialize.
This:
> java.lang.ClassCastException: org.apache.jasper.servlet.JspServlet
> cannot be cast to javax.servlet.Servlet
means that your libraries are messed up.
Specifically, that classes named
"org.apache.jasper.servlet.JspServlet" and "javax.servlet.Servlet"
were loaded by different classloaders and thus are not compatible.

and make sure that your web application does not redistribute Tomcat
libraries inside of its WEB-INF/lib directory.
I see that you are using Maven to build the project. It is known that
it can pull in a lot of odd stuff if not used correctly. There were
other users experiencing similar issue before, so search the archives
