Ok,
now I got the answer to the problem. First I created a decent GWT
module with the source code of charts4j and a charts4j.gwt.xml
containing:
<module>
<source path="charts4j" />
</module>
But then I found out it cant be done the way wanted. Unfortunately.
The problem is that there are some JRE-types used in charts4j, that
are not covered by the GWT-compatible subset of the JRE, eg:
DecimalFormat, URLEncoder. In the end this means that this library
cannot be used on the client side of a GWT application.
I'll now have a look at the GWT Port you suggested or using it in a
proper way (on the server side).
Cheers
Michael
