Using tJava for rename of current filename

Anonymous — Thu, 11 Oct 2018 06:24:50 GMT

For one Talend job, I use the tJava component to replace the name of the current file

Code:

String currentFileName = ((String)globalMap.get("tFileList_1_CURRENT_FILE"));

String newCurrentFileName = null;

String pattern = ((String)globalMap.get("Stichtag"));

String replacement = "20181010";

if (currentFileName.contains(pattern)){

newCurrentFileName = currentFileName.replaceAll(pattern, replacement);

globalMap.put(((String)globalMap.get("tFileList_5_CURRENT_FILE")), newCurrentFileName);

}

But if I’ll execute this Job I get an exception:

Exception in component tJava_3

java.lang.NullPointerException

Do you have any ideas, what is wrong?

Thanks in advance

tJava component is executed before other components for the same subjob. So, depending on your job design (not shared) à npe exception may occurs.
May be tFileCopy should be enough for your case.

Hi,

In first step, you are using tFileList_1_CURRENT_FILE but in later step you are using tFileList_5_CURRENT_FILE.

Could you please print and see the value in the variables to make sure that it is havign right values?

Hello,

yes, you are right. It was written by mistake. Now it works fine.

Thank you very much.
