Yeh thanks. I've already had some contact with the author of nstomcat. I believe his module is intended for general use as a web development tool using .jsp pages as an alternative to aolserver's tcl and adp pages. My focus is more to support the openacs porting effort by providing access to java library functions from tcl. This is intended to provide a path to port the sqlj stuff that aD is now using in oracle.
I've also had some contact with one of the tclblend developers, and I now think it might be possible to embed tclblend in aolserver. Though if I do that, it will only be supported for tcl 8.3 and higher.
