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

Requirements

1. I 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. I need to convert the JSON string into IPP Data Structure and present it to users for editing the IPP data.
4. Once edited, i need to convert the IPP data back to JSON string.

Steps:

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,
"Phones":[{"Home":"11111111","Mobile":"111111111","Office":"33333333333"},
{"Home":"2222222","Mobile":"2222222","Office":"34444444"}],
"dependents":[{"Name":"T1","Relation":"TR1","Age":21},
{"Name":"T2","Relation":"TR2","Age":43}]}

Results:

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

Next activity screen will present the data for read/write, make changes to it and complete the activity.

You will get JSON String out of edited data as shown below:

{"Phones":[{"Home":"11111111","Mobile":"111111111","Office":"33333333333"},
{"Home":"2222222","Mobile":"2222222","Office":"34444444"},{"Home":"6666666","Mobile":"6666666","Office":"66666666"}],
"Name":"Tanmoy Roy","dependents":[{"Name":"T1","Relation":"TR1","Age":21},
{"Name":"T2","Relation":"TR2","Age":43},
{"Name":"T3","Relation":"TR3","Age":56}],
"EmpID":"1002345","DoJ":1376332200000,"Salary":54433.0}
