There appears to be a significant momentum in the creation of interesting Java applets for Web use. Some relatively new to me are http://mc2.cchem.berkeley.edu/Java/ (small applets illustrating color) http://www.chimie.fundp.ac.be/javas/he_dz_java.html (a full blown SCF calculation on the helium atom) Lots of new molecular sketchers, including one ACD labs have kindly let us use for the ECTOC-3 conference http://www.ch.ic.ac.uk/ectoc/ectoc-3/mol_search_java.html and this one http://daylight.daylight.com/pmsp/ which is the fastest I have thus far seen. There are of course many other chemistry Java applets out there, but they seem to be hidden behind web pages that require registration (free or otherwise, such as http://www.java.isolnet.com/java/java_invds.html or http://www.tripos.com/discovery.net/top.html ) I certainly recommend also seeing e.g. the MSI Gene/Polymer explorer modules if you can get a demo. I also note that a new form of technology (programs written in C++ or other "old languages, but surrounded by a so-called CORBA wrapper and placed onto a CORBA server) can be accessed by Java applets in the client-server model. This allows server-side computations to be performed without the performance hit that Java sometimes imposes. Any good examples of this form of computing again please post to this forum. Finally, I note http://www.odi.com/ which mentions the adoption of a technology called PSE in Netscape and IE browsers. This is a so called "persistent object store", which in effect (as I understand it; elaborations welcome) can be used to create an object database out of Java classes cached by your browser on your hard disk. This sounds like a mechanism for greatly reducing download times for Java applets, and a technology which gives much room for thought (if it can be done for Java, why not for chemistry!!). If anyone comes across other molecule sketch programs or other interesting Java applets, do please post to this list.
