Configuring a Job using a tJavaFlex component

The tJavaFlex component is used to inject code at the start/end of a Job and to transform data transformations for each row.

A common Job using tJavaFlex is generally composed of:

a tFileInputDelimited component to read data from a text file,
a tJavaFlex to inject specific code at various moment of the Job processing (start, main or end parts),
a tLogRow component to print data in the console and processing information based on what the code injection says in the start and/or end part of tJavaFlex.

Procedure

In the Palette, slide a tFileInputDelimited , a tJavaFlex and a tLogRow component onto the workspace.
Connect tFileInputDelimited to tJavaRow and tJavaRow to tLogRow using a Row > Main link.
Set the Basic settings of the tFileInputDelimited component.
Double-click on tFileInputDelimited to display its Basic settings. The tFileInputDelimited reads the same text file and use the same schema as in the tJava and tJavaRow example .
When prompted, click OK to accept the propagation or click afterward on the Sync columns button in the tJavaRow Basic settings view.
Double-click on tJavaRow to display its Basic settings view. Add the following code in the Start code area:
```
System.out.println("******The subJob begins to work!******");
int nb_line=0
```

Add the following code in the Main code area:

row2.name=(row1.name).toUpperCase();
nb_line++;

Add the following code in the End code area:

System.out.println("The total number of processed data is: "+nb_line);
System.out.println("******The subJob finishes!******");

Note: This code converts the column names to upper case.
