What you are seeing is the effect of Tomcat only attempting to recompile every n seconds (4 I think by default). The first error is the failed compilation. The second is the result of the class that didn't compile not being present. To get the behaviour you want, make sure you have the following configured for the JSP servlet in CATALINA_BASE/conf/web.xml development=true recompileOnFail=true Once you have fixed the compilations problems you may want to reduce modificationTestInterval to less than 4 seconds.
