Stardust/Knowledge Base/Integration/Camel/JSON FILE TO IPP DATA


  1. Need to write a process which should be triggered when a file arrives at a particular folder.
  2. It should pick the file content (which happens to contain JSON Strings).
  3. Need to convert the JSON string into Stardust Data Structure and present it to users for editing the Stardust data.
  4. Once edited, need to convert the Stardust data back to JSON string.


  1. Create a RAD project and copy the xpdl into it. Copy all the source files as per its package structure.
  2. Download jackson-core-asl-1.9.10.jar and jackson-mapper-asl-1.9.10.jar and put it in WEB-INF/lib of the RAD project.
  3. Built the project, deploy the model.
  4. Place a file with itxt as extension in the designated folder which is being monitored by Camel Trigger (in thsi case its C:\temp).

File Content is:

{"Name":"Tanmoy Roy","EmpID":"1002345","DoJ":1376332200000,"Salary":54433.0,


As soon as the file is placed the process gets started and You will see it as below after completing Display File Contents activity:
