RE: spark-core in a servlet
Check for the dependencies. Looks like you have a conflict around servlet-api jars. Maven's dependency-tree, some exclusions and some luck :) could help.

spark-core in a servlet
Hi,
I want to use spark-core inside of a HttpServlet. I use Maven for the
build task but I have a dependency problem :-(
I get this error message:
ClassCastException:
com.sun.jersey.server.impl.container.servlet.JerseyServletContainerInitializer
cannot be cast to javax.servlet.ServletContainerInitializer
When I add this exclusions it builds but than there are other classes
not found at runtime:
dependency

artifactIdspark-core_2.11/artifactId
version1.2.1/version
exclusions

What can I do?
Thanks a lot!,
Ralph

Re: spark-core in a servlet
I am not sure if this could be causing the issue but spark is compatible with scala 2.10. Instead of spark-core_2.11 you might want to try spark-core_2.10 On Wed, Feb 18, 2015 at 5:44 AM, Ralph Bergmann | the4thFloor.eu ra...@the4thfloor.eu wrote: Hi, I want to use spark-core inside of a HttpServlet.
