hi all,
i am trying to send response entity from my java class ,and in the gateway condition i want to check if the status is 200 then move forward or else the token stays there only.
how can i use this in my XOR gateway condition?
example- i am trying to do ${status==200}
which is not working.
Any help is welcomed.
I need a lot more information -
upload your model
show the code where you’re setting the status variable and maybe also explain a bit about what you mean by “not working”.

Niall what i am trying to do is i have a java connector class where i am returning
return ResponseEntity.status(HttpStatus.ACCEPTED).body(status);
now what i want is only when my statusCode is 200 it should cross the Gateway or else it should go back to the “send task”.
Now when i am trying to create a new instance, it is throwing the following error in Postman
{
"type": "RestException",
"message": "Cannot instantiate process definition change4:1:f90af069-0a05-11eb-a393-8c1645ee0634: Unknown property used in expression: ${ResponseEntity.status(200)}. Cause: Cannot resolve identifier 'ResponseEntity'"
}
Thank in advance 
You should create a variable for the response code as part of the output of the connector, then the gateway will have access to it.
Understood thank you @Niall
And one more thing Niall if for the following flow
if i want to set the number of retries to be 3 max and if it exceed it should terminate the process,how do i set that boundry event?
You can set a variable on a listener at the beginning of the gateway and then add an additional clause to the gateway
e.g.
#{status == 200 && attempt < 4}
@Niall if there any way other than listener,i want it to be done from the camunda’s side only without the intervention of any java class.
The listener can be a script embedded in the model without requiring a Java Class.
hi niall,
as in the image above you can see as you told en the sequence flow just at the starting of the gateway i have included the following listener,
please check if this is the right way to do so,
i have a CONNECTOR in my Send Task which has output paramter as VALUE
and now i have implemeted the above ,
when the attempt becomes 0 the CONDITIONAL BOUNDARY event should hit and end the process,But still it is going into loop.
Can You please Help into this?
The script you have there will reset the value to 4 each times it’s run.
You’ll need to check first if the value is null - only set it’s null you set it to 4 otherwise you decrement it.
