Peter,
MyEclipse only compiles JSPs for validation purposes. We assumed that JSP development would seek to take advantage of most appserver’s ability to dynamically compile/recompile and load JSPs incrementally. For production purposes where compiled JSPs typically come into consideration we assumed precompilation would be handled by an external build process.
Also it is my understanding that most appservers apply their own servlet class and packaging naming conventions when translating a JSP. In such cases the compiled JSPs will not be generally portable between appservers.
