The issue of too many jsp files loaded is an issue for us as well. We have a CMS system that generates jsp files as its output and while it is not the best model for publishing content, it is certainly easy! We have > 10,000 jsp files generated through templates putting a mixture of static and dynamic content on the pages. The solution is not to buy more memory as we are on a 32-bit machine and have given all available user mode memory to the jvm.
I do not think that it is a isolated case, but a very significant problem, and a significant number of application servers have the ability to set the number of cached templates/what have yous - even IIS3! I am working on a patch which addresses some of the issues raised in the thread, such as turn-on-able and not altering the code path too much in it off state. I think that also the issue of unloading is not valid, as it already happens when a dependant file changes and the jsp is recompiled. Of course if the jsp had a one time only initialization requirement then the developer could specify not to enable the LRU cache of jsp servlet engine. I think that the externalizing of static string data is a diversion on the problem, but I would go for a single buffer and use JspWriter.write( cbuf, offset, length ) to sent the right portion. So, what are the requirement to getting a patch accepted in tomcat 5.5?
