How to have multiple response in one request?

[jerownimow]

I have a job that requires 2 responses, the structure is like this.

Can you help me figure out how can I facilitate these 2 succeeding responses?

Try to send an interim response with code 102 for "Processing".

Thanks for your reply. How can I configure it? Do I have to add two
tRESTResponse and one is configured with custom status code?

[TRF]

Yes, 2 tRESTResponse components.

For the status code, yes, select "<< custom >>" and enter 102 for the value, this the only way to use a status code which is not preconfigured into the component.

However I can't guarantee Talend authorize 2 responses for 1 request but it should as it is a standard behavior for REST services.

Thank you for your inputs @TRF.

However, it didn't worked, I still got this error java.lang.RuntimeException: Rest response already sent.

My first reflex was to say it is not possible.
Then I saw a post regarding the proposed solution. Finally it seems this is not supported by tRESTResponse.
You may try with a piece of Java code to send code 101.

Unfortunately, I'm not good with Java, can you give me a suggestion how to do it? I'm trying to google it but I can't seem to find one.
