Thanks, Mike.
I have not used servlets or JAXP at all and have hardly done any programming in Java, so it might take me a while to figure out the solution you've proposed. Meanwhile, I decided to eliminate the parameters passed as command-line arguments to Saxon so as to transform the XML into HTML in the browser itself. When I tried doing so, I get the following error: "Error during XSLT transformation: XSLT transformation failed." I have tested the XSLT and am sure it works; and I have been able to use the browser to do the transformation with the previous version of this XSLT I had. The main (and am sure important) difference with this XSLT is it is conformant to XSLT 2.0 standards while the previous one was conformant to XSLT 1.0. That is, I am using for-each-group now instead of for-each loops and this is probably what's causing the error (my guess). Is this the source of the problem or is it something else? Please advise.

Loading and initializing a Java VM just to run one transformation is not the way to do things in a web service environment. (It can take 5 seconds to load the VM to run a 50ms transformation.) Write a Java servlet that runs in a container such as Tomcat which keeps the VM alive, and use the JAXP API to drive the transformations. There's a "starter kit" servlet for doing this in the Saxon distribution. > but it doesn't work - I am > seeing the following error in the webserver error logs: > > *** glibc detected *** java: free(): invalid pointer: 0xbfc7cbb8 ***, Sorry, that's not an XSLT or Saxon problem, it's something to do with the configuration of your web server.
