It's called JSP compilation. Precompile your pages.
Are you saying that the JSP precompilation performed by the servlet-engine get's lost and I need to manually precompile my pages when the time has been set back compared to the ear's timestamp.
whereas in normal cases this is not nessesary.??
Doesn't make much sence do you think?
When u change the time, the lastmodified time will be different and the JSP Compiler thinks that the file has changed(due to timestamp difference) and recompiles it. I Think thats what Juha meant.
Ok now I see what you mean. But how to avoid that?. Would the JSP compiler not touch the generated files if they are pre-compiled, whereas it would if the JSP compiler should compile them?. Seen from the JSP compiler point of view there should be no difference??
