Yep, we use tha AElfred xml parser in ptII/com/microstar/xml AElfred is a little bit limited, but it works for us. > In general, I can't see any way to add to the classpath used by > Ptolemy when it is launched from Vergil, which is a major > inconvenience. Is there any way I can affect the classpath? I'm assuming that you have cygwin installed, and rebuilt everything from scratch using make, then $PTII/bin/ptinvoke.in gets linked to $PTII/bin/vergil, ptinvoke.in should be reading the CLASSPATH variable and appending it to command line. The way to test this is to start up bash and do something like: CLASSPATH="c:\\your\\jar\\file.jar;c:\\your\\other\\jar\\file.jar" export CLASSPATH sh -x $PTII/bin/vergil Another way: Assuming that the classes you want to add are in a jar file, you could edit ptII/bin/ptinvoke.in and add your jar files to the ALL_JAR line and then run make install in the bin directory Yet another way, not recommended: If you are using the installer and you did not rebuild from scratch using make, then adding classes is more complex. I think the vergil startup executable will check to see if ptII/lib/user.jar is present. You could jar up your classes and put it there. To do this, you need to unjar your jar files and then rejar them Something like: mkdir tmp cd tmp jar -xf yourjarfile.jar jar -xf yourotherjarfile.jar jar -cf user.jar . cp user.jar $PTII/lib/user.jar If that does not work, you could try adding the jar files to lib/diva.jar something like: mkdir tmp cd tmp jar -xf yourjarfile.jar mv $PTII/lib/diva.jar $PTII/lib/diva_old.jar jar -xf $PTII/lib/diva_old.jar jar -cf diva.jar . cp diva.jar $PTII/lib BTW - I'm really unhappy with the Installshield installer, so if you are serious about using Ptolemy and writing your own actors, you should definitely download the source and build from scratch > Thanks, > > Robert E.
