Configuring the tJavaFlex component

Procedure

  1. Double-click tJavaFlex to display its Basic settings view and define the components properties.
  2. Click Sync columns to retrieve the schema from the preceding component.
  3. In the Start code field, enter the code to be executed in the initialization phase.
    In this example, the code indicates the initialization of the tJavaFlex component by displaying the START message and defining the variable to be used afterwards in the Java code:
    System.out.println("## START\n#");
int i = 0;
  4. In the Main code field, enter the code to be applied on each line of data.
    In this example, we want to show the number of each line starting from 0 and then the number and the random text transformed to upper case and finally the random date set in the editor of tRowGenerator. Then, we create a condition to show if the status is true or false and we increment the number of the line:
    System.out.print(" row" + i + ":");
System.out.print("# number:" + row1.number);
System.out.print (" | txt:" + row1.txt.toUpperCase());
System.out.print(" | date:" + row1.date);
if(row1.flag) System.out.println(" | flag: true");
else  System.out.println(" | flag: false");

i++;
    Information noteWarning:

    In the Main code field, "row1" corresponds to the name of the link that connects to tJavaFlex. If you rename this link, you have to modify the code.

  5. In the End code field, enter the code that will be executed in the closing phase.
    In this example, the code indicates the end of the execution of tJavaFlex by displaying the END message:
    System.out.println("#\n## END");
