tJavaFlex java.lang.ArrayIndexOutOfBoundsException

[Anonymous]

Hi, I'm trying to parse strings into key-value pairs in a tJavaFlex so they can be loaded by tContextLoad in Talend Studio 6.4.1

tSubJob - loads a config file and outputs the variables as a string  i.e. "Username;admin;" "Password;123;" etc

|

tJavaFlex - split into key-values

|

tContextLoad - load into environment variables

the code in tJavaFlex is 

String [] kvPairs = row6.contextString.split(";");
row5.key = kvPairs[0];
row5.value = kvPairs[1];

But i get the error below. row6 is definitely the input row and 5 the output. 

Exception in component tJavaFlex_1
java.lang.ArrayIndexOutOfBoundsException: 1

Anyone any ideas?

The above is done in the main section of tjavaflex btw

This suggests that your String being split does not have a semicolon in it. The java.lang.ArrayIndexOutOfBoundsException exception is a standard Java exception indicating that the array does not have the number of elements you are expecting. Can you just print the value held by row6.contextString in your tJavaFlex....

System.out.println(row6.contextString);

Many thanks rhall when i inspected the output it was a null value for one of the values which was causing the issue. Have managed to fix it now.

Good one. Actually I would enclose this kind of iffy code in try {} catch{} block.
