Re: difficulties with example

[Jamie Orchard-Hays]

Did anyone solve this? I'm having the exact same error (hm1.0).

I had already done this. But for kicks, I did it again. From the hivemind root, I ran "ant install" this built the project and ran numerous unit tests successfully.

From the root direction, execute "ant" or "ant install".  This will
compiled the source code, and generate the hivemind libraries (which
appear to be missing).

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:

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