Hi Sumit,

Activities in Trident need to be coded in .Net framework.
As far as I know, it is not possible to develop a Trident workflow in java.
However, if you wish to invoke java code from within a Trident activity, one way to do so is by invoking it using Process class which provides command line functionality. Another way is to host your java code as a web service and invoke the service using a webservice client from within Trident Activity.  

In my opinion, since Azure API is available for C#, it might be a more straightforward to develop a Trident Activity which uses C# Azure API to upload to blob.

Hope this helps.

Hi Kavitha,


Thanks a lot for your quick reply. You are right even i could not find any information about writing trident activity in java. I have been trying to implement it using C# from last few days. But i am not aware of much of C#. So its taking time to understand.   I have better understanding of java code. 

I have one more question need to know. I have applied for Azure connect access through management portal in last week. But my request has not been processed yet. Do you have any idea how long usually it takes to get activated.

For uploading a file in azure blob i need to have azure connect access.. Am i right.?

Hi Sumit,

I dont think you need Azure connect access to upload to Azure blob.

You might find more information on Azure storage at
