ILOG – JViews Gantt

Seems like JViews Gantt is a good candidate for one of the projects that we?re currently developing. We?re interested in having an output similar to that of Microsoft Project in a thin-client environment (JViews Gantt capabilities sounds good). It still too early to decide weather it?s the right solution (JSP tags, features, ease, scalability, etc…). Does anyone have an experience with it?
