How to set context boolean variable in tJavaRow output

Edith1 — Tue, 21 Jul 2020 23:27:28 GMT

I want to change the Boolean context variable based if the data field is null. I have tMap connected to outputs tJavaRow & tLogRow_3.

Here's what

I have in the tJavaRow code:

output_row.entity_id

= input_row.entity_id;

(input_row.entity_id != "")

{

context.Has_Objects

= true;

}else

context.Has_Objects

= false;

System.out.println(context.Has_Objects);

Here's what

happens when I run the job - it sets the context to true when there's an id,

but nothing is written when there's no id.

The tLogRow_3

shows the 1st record has ids and variable was set to true, however the 2nd

record there was no id and I don't see the variable set to false.

Change your code to:

output_row.entity_id

= input_row.entity_id;

(!input_row.entity_id.equal(""))

{

context.Has_Objects

= true;

}else{

context.Has_Objects

= false;

}

System.out.println(context.Has_Objects);

Please try and let me know if it works.

Hi @Shicong Hong, when I changed it to the code you provided, I am getting the following error:

"Detail Message: The method equal(String) is undefined for the type String. There may be some other errors caused by JVM compatibility. Make sure your JVM setup is similar to the studio."

I checked my preferences and do have -Xms256M and -Xmx1024M for Job Run VM arguments under the Run/Debug tab and I also have Java Compiler level to 1.8 and use default compliance setting. Anything else that I'm missing for this to work?

@Edith Murillo , sorry, there is a typo in the code, change it to:

output_row.entity_id

= input_row.entity_id;

(!input_row.entity_id.equals(""))

{

context.Has_Objects

= true;

}else{

context.Has_Objects

= false;

}

System.out.println(context.Has_Objects);
