Image in ADF form, through BPM binary datatype

Question

hi All,
I have a scenario in bpm 11g, where a user will upload the image file and after process completion it will persist to database. I tried defining the binary datatype for holding that image, but that binary type is not displaying as image in any subsequent task. Additionally, i fetched the Blob type, containing image from the database through database adapter, it also is not been shown in the adf data table. What am i doing wrong? (Found a servlet work around, but want this to be done through bpm drag and drop). Is it possible?
Thanks

Hi Asad, I'm sorry for this late answer :(
Please follow this steps:
1- Create a new manage bean with request scope.
2- Select from the page the image component and go to the property inspector in the attribute bindings and edit it, select the manage created and write a name for the component. You w'll see in the manage the attribute created.
3- In the manage bean, put this (private UploadedFile _file;) as an attribute from the class and create the accessors.
4- Do the same thing for the property value for the inputFile componet, select the manage and then the field _file* .
5- For the inputFile select, in the property valueChangeListener select the method in the manage and set true to the property AutoSubmit
The Manage can be this one, adapt it if you need it:
I already test it, so I realy hope this work wor you:
Note: Create the directory "img/tmp" in the public_html folder of the project
