Unable to access global variable from tsystem component

Anonymous — Tue, 28 Aug 2018 14:46:57 GMT

Hello,

I am trying to access global variable set from tjavarow in tsystem component.

The global variable referenced is not present from tsystem component and am getting below error. Can someone please help ?

Exception in component tSystem_1 (weathersolutions)
java.lang.NullPointerException
	at java.lang.ProcessBuilder.start(Unknown Source)
	at java.lang.Runtime.exec(Unknown Source)
	at java.lang.Runtime.exec(Unknown Source)

Please refer ti image globalvariable.png which contains the global variable addition and am referencing it in tsystem component using

(String)globalMap.get("body_data")

But am getting nullpointer exception

row3.getBody() ...
should be : row3.columname

Should be input_row.columnname

@TR They both work, at least within tJavaRow, also tested it to make sure. And in other components I've always used row.columname.

input_row.columnname
row3.columnname

However same result.

Any particular reason why to use input_row or something you prefer to use, older Talend version?

Cheers
