For what it's worth, I've included my servlet code underneath my signature. I'm still new to ABCL and this is just a quick hack, so beware, but it works for me. I auto-load the servlet, so the time for starting ABCL is not spent after the first request. On Jan 9, 2010, at 1:24 , Blake McBride wrote:
Greetings,
I am considering using ABCL as an extension language to a Web server app I have. I know the answer to many of the questions I have in choosing the correct extension language and ABCL seems to fit the bill well. I do have some questions, however.
