Hi Jeff,

The error you are getting is basically saying that Ant can't find the class files where the build.xml file is saying to look for them so it can't put them in the .jar file. You are right, it's creating the jar, but then not putting anything in it.

It's been a long time since I tried to build any of the Practical Utilities stuff, and I don't think I've ever tried with WOLips. I think the problem you are running into is that the Practical Utilities projects are all Xcode projects, not Eclipse (WOLips) projects. I think you'll need to follow the instructions for converting a Xcode project to a WOLips project before you try to build it.

Instructions for that are located in the Wiki: 
http://wiki.objectstyle.org/confluence/display/WOL/Import+an+Xcode+project+into+WOLips

A word of warning about the Wiki, there will be times where you run into instructions there that don't match with what you are seeing in your copy of WOLips. This is because there is a huge amount of work being done on the WO Development tools, and things change almost daily. Don't let this discourage you because things are getting more intuitive every day. If you see a tutorial that you can't reconcile with what is actually happening in Eclipse, post a question to the WOProject or WO-Dev lists and I'm sure someone will be happy to help you, then feel free to update the Wiki to help the next person!

Dave

Hello,
I've tried to import the practical webobjects utilities framework project per instructions of pgs 335-336 of the book, but when I use the WOLips Ant Tools->Install command on the build file to install it, I get the following warning:

Warning: skipping jar archive /Library/Frameworks/ PracticalUtilities.framework/Resources/Java/practicalutilities.jar because no files were included.

when I look at the practicalutilites.jar produced, it seems to be an empty jar (it's 4kb in size). Any ideas? I can see all the source files in the WOLips project within the src project folder.

Thanks,
Jeff
