JspC: unable to precompile linked jsp files





------- Additional Comments From daniel_collins@tertio.com  2003-12-05 16:21 -------
We have the same problem in our development environment. I wanted to precompile 
our JSPs (for performance), but our version control system creates all files in 
the workarea as symbolic links to another area of the disk hence our JSPs 
couldn't be compiled. (As an aside it also got thrown by the JARs in WEB-
INF/lib being symbolic links as well).

I remember there was an earlier bug (#12049) related to symbolic links and 
security seemed to be the problem (which I can understand, in a real webapp you 
wouldn't want symbolic links to other parts of the disk where files could be 
tampered with), but for standalone precompilation it shouldn't be a problem.
I would have thought that Tomcat (or whatever server you are using) should 
really handle the issue of symbolic links being allowed or not but I'm not that 
well up on it really.

I found 3 places in JspC.java that were using getCanonicalPath() that caused me 
problems -
initClassLoader() for the JARs,
locateUriRoot() only used if you don't specify -uriRoot,
execute() where the pathnames for the JSPs are converted to URIs relative to 
uriRoot.

I've patched our system locally to allow us to compile these links (security 
isn't a problem since its only for precompiling in our development area), I'll 
tidy that up a bit and submit it.
