[seam-dev] Ideas for a replacement of the seam 2 PDF tags/engine in a CDI/JSF 2.0 world?

[Denis Forveille]

Yes iText "new" license could cause some trouble.  I could stick with iText v4.x but it is end of life

Maybe rewrite the tags with the PDFBox library instead of iText?

Or maybe you know another FOSS lib for that?
