I am planning to develop a web based work flow system which also provides drag-n-drop option of different entities for workflow creation and form builder. Primarily I am looking a solution in PHP but if could not then I can go for Java.
I got something about ezComponnts but I also need a Visualization, something like this so I wonder what could be the best bet for me? ezComponnt looks good programatically, is there anyway I can integrate visual interface and a Form builder in it? Or I make visual builder as a Desktop program and then export the entire workflow in some TextFile?
Check out ProcessMaker, which provides most of your requirements.
