Hello everybody ...
I was playing with the file upload, it seems that it works for me ...
Might be somebody will find it usefull. Changes in brief:
ChibaBean:
updateControlValue(String id, String contentType, String filename,
byte[] data)
- to be called from the EnvironmentAdapter
Upload, Filename, Mediatype:
setValue(...)
- Upload.setValue will convert the byte[] array to the
base64 or hex char stream, that will be stored into
the proper instance element, then it will try to locate
xforms:filename and xform:mediatype elements and
invoke theirs setValue() ...
You need the commons-codec-1.2.jar from jakarta.
