I want to make an App Engine app that will display xml content that is transformed by an xsl file. I'm using the GAE Eclipse plugin for development.
I want to put the xml content in a jsp page so that I can collect form data based on the displayed xml. I am new to App Engine and jsp, and things are not as straight-forward as I'd hoped. I've copied snippets of my xml and xsl files below. I've also posted two different jsp attempts that I've made and their accompanying errors. I suspect my problem might have to do with the jars I'm using, so I've also included a list of the jars that are included in my project.
I've waded through a ton of documentation, but I can't figure this out. Any suggestions would be much appreciated!
