Re: Servlet based implementation of brl.

I have parts of brl working using the current kawa svn, using a slightly

The scheme files which comprise the brl implementation need to be loaded
in the servlet init function. Can I use Language.getLanguage("scheme")
in the servlet init, and then use it to load the scheme class files?
It looks (from the rest of your message) that you're using
gnu.kawa.brl.BRL, which is my preference and recommendation .
In that case presumably you would import the needed definitions
in the BRL, not the servlet level. I.e. modify/extends the
loadClass class in initBRL. It seems that's what you're doing,
so I'm not sure what you're asking.
Will the call to Language.getInstanceFromFilenameExtension in getModule
from the servlet run method use the same namespace as the one created
when I loaded the scheme class files?
I think so.
Following are the files I needed to change:
kawa\standard\require.java - include require of srfi-13.
gnu\kawa\slib\srfi13.scm - download of srfi-13 reference implementation
from schemers.org
gnu\kawa\servlet\HTTP.scm - additional functions to support brl.
gnu\kawa\servlet\KawaPageServlet.java - define brl-servlet-output-port.
gnu\kawa\brl\BRL.java - additional loads of files.
gnu\kawa\brl\progfun.scm - rewrite macros.
gnu\brl\netfun.scm - added.
gnu\brl\repeat.scm - added.
gnu\brl\webfun.scm - added, modified to use functions in HTTP.scm.
build.xml - added files, modified classpath.
Looking promising. I'd me happy to look at your patches and
maybe check them in.
