Ok what about the ant variables? I've got ANT_HOMEand JAVA_HOME and have no idea how to set them. Bill

JAVA_HOME, as said upthread, is used by more than Ant.

You set environment variables in the way specified by the operating system, not Java. Martin Gregorie wrote: > Its basic operating system stuff.

Dunno what it is for XP. Last but not least, if you're smart you'll put symbolic links in place, e.g. use one called C:/SDK that maps to C:/java/jdk1.6.0_u20 and do the same for Ant. Use the symlinks in environmental variables rather than the actual paths. The advantage is that, when you upgrade Java or Ant you simply swap the symbolic link to point to the new package without having to hunt down and change the environment variables. Disclaimer: the symlink trick works for Linux. I assume it also works for XP - if not, why would MS bother implementing symlinks? -- martin@ | Martin Gregorie gregorie. | Essex, UK org |

I also include the \bin in there so that might be part of my problem. I have also been including the bin directory. Bill |
