• Seam Framework – How do I use multiple dynamic EntityManager's in Seam?
  For the purposes of this article a Seam project named example will be used. This is only important in regards to remembering the default generated naming of the persistence unit and other configuration, ect… which will default to the project name, example.

• byte array as a parameter in JasperReports (Open Source Projects forum at JavaRanch)
  I found the solution to my problem, I'll put the solution here if someone has the same problem.
  I was defining byte array parameter as an object and when I was adding it to the page it was by default added as a String in text field. The byte array was image which I wanted to display on the report, so first I had to convert byte array to ByteArrayInputStream on the Java side, define parameter as type InputStream, and then display it within the image, also as InputStream type.
