Class org/apache/wicket/Component violates loader constraints
People,I was working with WTP to debug my wicket app. But I decided to move
to jetty because there is no need to deploy de app, as I imagine that WTP
does. I changed from Eclipse->Project->Java-build-path the directory where
my class are compiled: src/main/webapp/WEB-INF/classes. I debug Start.java
where it says:
...
WebAppContext bb = new WebAppContext();
bb.setServer(server);
bb.setContextPath("/misDeportes");
bb.setWar("src/main/webapp");
...
But when I tried to login I got this expcetion. I really know what to do: I
mean I dont know anything about class loaders and how I reached this
situation.
Thanks in advance!

Martijn & Serkan,
I solved this problem with eclipse m2 plugin. I installed it and I
could debug my app inside eclipse with jetty.
I was looking for any duplicity or some compiler version problem, but
I was having a hard time.
Thanks!

it also probably indicates that wicket-xxx.jar exists in multiple
locations within the application server..

wicket version, OS version, Java version would be nice to have in such
a scenario. Did you try to generate a new quickstart and see if that
works?
