Subject difficulties with example
Date Thu, 30 Dec 2004 00:13:34 GMT
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

BUILD SUCCESSFUL
Total time: 1 second


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

java.lang.NoClassDefFoundError: org/apache/hivemind/ClassResolver
	at org.apache.hivemind.examples.CalculatorMain.main(CalculatorMain.java:32)
Exception in thread "main" 

Any suggestions would be welcomed.
