My projects relies on Spring Boot to build standalone executable jar files. It works great for internal testing. However, once we are ready to deployment it to our development environment, applications need to be in a war file so it can be deployed to our Resin server.
So I followed the guide (http://spring.io/guides/gs/convert-jar-to-war/) and did the conversion. Then I deployed the war application to a local Resin server and a long series of exceptions occurred.
Long story short, I ended up creating a simple hello world REST service using Spring Boot that builds as war and deployed it to Resin. The test application is at (https://github.com/ChrisZhong/spring-boot-war-sample). Similar problems occurred with the test application. But, the same test war deployed to Tomcat 7 without any problems and worked as intended. The following log is from Resin.

I am told by a colleague who has some experience with Resin that there is a problem with loading the jar files as indicated by the ! at the end of each jar file.
For some reason Resin enforces that filters (programmatically?) added to the context must have a public modifier. The ErrorPageFilter in Spring Boot is package protected and as such fails that check (check the sources for both Resin and Spring Boot).
I can imagine this check for Filters that are added through the ServletContext.addFilter(String, Class) method. Not for the method ServletContext.addFilter(String, Filter). The latter is used by Spring Boot to register the filters.
I would consider this a bug in Resin.
