First, although deploying web apps is not by day job, I have been following
Tapestry for some time. This is how I stumbled into Hivemind. I am excited to
see so much progress in such a relatively short period. Thanks to Howard and
team for their efforts.
I have attempted to run the examples that I downloaded with hivemind-1.0.zip.
Being new, I'm sure I am making simple errors, but have not been able to find
an answer on the mailing list archive.
I am using Ant 1.6.2
The first problem I encountered was that the file "grabber" could not open the
URL's. I assume that this is because of my firewall. I was unable to find a
proxy setting, so I downloaded the required files by hand and put them in
{hivemind}/ext-package/lib. This allowed me to continue. I was then able to
build the "compile" target sucessfully using Ant from the command line.
However, I am unable to invoke the "run-calculator" target while running Ant
from the command line, or through Eclipse. I get the following error:
Buildfile: C:\data\Download\java\hivemind-1.0\examples\build.xml

If I attempt to run the example directly through Eclipse, I get this error.

Any suggestions would be welcomed.
