If you have problems following the tutorial all the way through --for example, Ascape won't build -- it is probably due to an error in the installation guide URL I corrected a few hours ago. That URL was for a test site and had a two day old version on it. ;( You can try updating using the manager, but if you just downloaded Eclipse it will probably be simpler to dump your current version and start with a fresh copy.

Otherwise, let us know how our install went and what we can do to make things easier or more clear for future users!

I followed along fine until I tried to run the models I downloaded (from http://www.metascapeabm.com/index.php?option=com_remository&Itemid=55&func=select&id=2) and dragged to the project window. I get the following exception in the console, and the models do not run:

Thanks for the report.

First, to be clear, the model did build, but you were unable to run the model? (The warnings are expected -- the Eclipse default build settings are pretty zealous.)

1. Can you verify the creation date of the file org.ascape.common.lib_5.0.1.jar
[correction from: org.ascape.common_5.0.1.jar] in your eclipse install plugins dir?

It should be:

2007-11-17 15:04 and if you unzip it should include a quicktime dir at the base level.

2. What OS and version are you running?

3. Please right-click on the project, choose "Build Path..." : Configure Build Path" and select the Libraries tab. There should be an entry for org.ascape.common.lib_5.0.1.jar that on the left side has ECLIPSE_HOME and on the right the actual location of that file on your machine.


Has anyone else had this issue?

Thanks for your response. I don't see any model.

1. The create dates for both the org.ascape.common.lib_5.0.1.jar and org.ascape.common_5.0.1.jar files show as 2007-11-23-16:45 PM. I don't see any Quicktime directory. I attach a screen shot of the unzipped library file.

2. I am running Windows XP Home SP2.

3. I see what you describe for both org.ascape.common.lib_5.0.1.jar and org.ascape.common_5.0.1.jar. I suspect from your "correction from" language that I should have only the ....lib.jar, and further that having both is possibly causing my errors. Do I have an uncorrected and corrected version? If so, how do I clear out the uncorrected one: delete it in Windows Explorer, or in some Eclipse project manager view? Any other backing out or starting over you would recommend?

No, you need both -- I just wanted to make sure that you were looking in the correct directory. I had a Quicktime issue recently over in the Ascape forums, and I suspect there is what is happening here. There hasn't actually been a lot of Wndows testing yet..

I don't see the screen shot.. Could you just paste in the first level of the expanded .jar. e.g. it should look like somthing like this:
