Is there something similar to the mini-mvc-profiler for Java?
I\'m looking for something that can be used in a Struts or Sp
java-mini-profiler
This is one I wrote which takes from gae-java-mini-profiler but works for non-gae applications. It also some extra features which can be optionally enabled such as profiling annotation and sql profiling.
I would recommend: gae-java-mini-profiler

The simplest can be Java Interactive profiler
Another interesting and effective one is glassbox
It depends on case to case basis. Sometimes even using a simple performance logging library like per4j works.
