Java service to navigate Document (IData with complex structure)

, ,
1

Hi,

I have written a java service in wM 8.2 to modify the Document (with complex structure) at run time.

e.g. Say input to the service is “inputDoc” with complex structure

inputDoc (Document - IData Object)
-----strField1 (String)
-----strField2 (String)
-----internalDoc1 (Document - IData Object)
----------internalDoc1StrField1 (String)
----------internalDoc1StrField2 (String)
-----internalDoc2 (Document - IData Object)
----------doubleInternalDoc1 (Document - IData Object)
---------------doubleInternalDoc1StrField1 (String)
---------------doubleInternalDoc1StrField2 (String)

I would like to convert each leaf node i.e. strField1, strField2, internalDoc1StrField1… to a Document “info” and add three fields in it “key”, “value” and “type”

Here is the code I am using:

}

------------------------ End -------------------------

The output is coming, but not in the way I want, can anyone please suggest me where I am going wrong. The output I am looking for is:
outputDoc (Document - IData Object)
-----info
----------key (String)
----------value (String)
----------type (String)
-----info
----------key (String)
----------value (String)
----------type (String)
-----internalDoc1 (Document - IData Object)
----------info
---------------key (String)
---------------value (String)
---------------type (String)
----------info
---------------key (String)
---------------value (String)
---------------type (String)
-----internalDoc2 (Document - IData Object)
----------doubleInternalDoc1 (Document - IData Object)
---------------info
--------------------key (String)
--------------------value (String)
--------------------type (String)
---------------info
--------------------key (String)
--------------------value (String)
--------------------type (String)

Thanks in advance!

and what is the output you are getting?

Only one info obj is created and under that twice the key, value, type are coming

It’s coming like this!

I m not able to see complete thread, as I am replying thro my smart ph, will reply in detail.
Sorry about that!

Did you try this:

  • Define a document type conforming to the structure and field names of the source document
  • Define another document type conforming to the structure and field names of the target
  • Use FLOW service steps to map

Hi Reamon, this java service I want to use as a generic service for any document structure.
At run time, my code is reading the document structure and then modifying the fields if the field is not an IData object.

Hemanth,
yesterday, by mistake I copied the contents from the first thread and pasted in the response I was sending you.
Here is the output the code generates
-----info
----------key (String)
----------value (String)
----------type (String)
----------key (String)
----------value (String)
----------type (String)
-----internalDoc1 (Document - IData Object)
----------info
---------------key (String)
---------------value (String)
---------------type (String)
---------------key (String)
---------------value (String)
---------------type (String)
-----internalDoc2 (Document - IData Object)
----------doubleInternalDoc1 (Document - IData Object)
---------------info
--------------------key (String)
--------------------value (String)
--------------------type (String)
--------------------key (String)
--------------------value (String)
--------------------type (String)

In this output, if you see it is not adding IData object “info” for all three fields which I am adding to the output document.
Hope this answers your question on the thread…

Thanks Reamon, for formatting the thread contents, it’s much readable form now.
Just one thing was missing, my desired output is missing :).

I am looking for the output to be:

outputDoc (Document - IData Object)
-----info (Document - IData Object)
----------key (String)
----------value (String)
----------type (String)
-----info (Document - IData Object)
----------key (String)
----------value (String)
----------type (String)
-----internalDoc1 (Document - IData Object)
----------info (Document - IData Object)
---------------key (String)
---------------value (String)
---------------type (String)
----------info (Document - IData Object)
---------------key (String)
---------------value (String)
---------------type (String)
-----internalDoc2 (Document - IData Object)
----------doubleInternalDoc1 (Document - IData Object)
---------------info (Document - IData Object)
--------------------key (String)
--------------------value (String)
--------------------type (String)
---------------info (Document - IData Object)
--------------------key (String)
--------------------value (String)
--------------------type (String)

if you see the output coming from the java service is missing the “info (Document - IData Object)” at one more level…hope I am giving all the details to get solution and suggestions from experts :).

You need to do IData info = IDataFactory.create(); every time you want a new “info” document. You’re only doing one.

Hello Everybody,

I am able to create the similar kind of output if not the same one which I was expecting out of Java Service.
Here is the code I would like to share with you:
Note: “In the input/output tab of the java service add input as a document “inputDoc” and in the output tab add “outputDoc”.
You can call this service in any Flow service and map any document to inputDoc and get the result in outputDoc.”

Reamon, please format it in the same way you did earlier, so it would be in readable form.
Thanks for your help!

You can add the formatting. Just put [ code ] [ /code ] tags around your code. Remove the spaces that I added here to avoid it being interpreted.

Thanks Reamon, I updated the post.
