Re: [Jetty-support] jetty can't compile a JSP ?

[Chris H. <ch...@ha...>]

There's not enough error listing from the compiler to work out exactly
what has gone wrong.

Here are some well-known Gates Gotchas to check.

You don't tell us which particular OS you are using. I'll assume it's
an earlier type of Windows. The DOS command system ( present, I think,
in all versions up to and including W2000) has a limited amount of
space allocated to the environment variables (in which the classpath,
java_home, jetty_home etc. etc. all have to be stored). I think the
shipped default is 256 bytes!

In your AUTOEXEC.BAT file you need to put
    SHELL=command.com /e:32768
which should give you enough space for all needed environment
variables, including the classpath. If you have a later Windows
version you may have to hunt around to find out how to have the same
effect, or it may move it into the Registry for you on rebooting.


The other things to check are:

(1) Make sure the capitalization of all drive and file names matches
that shown when you use DOS to list the files,

(2) Here's a great one:  You have correctly used the DOS 8-character
short-form (PROGRA~1) etc. *however* the serial number ~1, ~2 etc.
depends on how many other names have the same first 6 characters in
that same directory . So, if you set up a script which uses PROGRA~1
as the DOS alias for 'Program Files' and on a different machine there
is a second name 'ProgramFiles' (no space) to the same directory, the
abbreviated form of 'Program Files' (with a space) could change to
PROGRA~2.  In other words the 8-character DOS abbreviated names
interact with one another!  In your case I would be suspicious of
LOCALS~1.
