It is not evaluation the below condition in pi ( if (a.equals("F") && (b  != ("03"))))

String a = "F";

                    String b = "4";

                    String c= "";

                    System.out.println(a);

                    System.out.println(b);

                              if (a.equals("F") && (b  != ("03")))

                              {

                              c="test";

                              System.out.println(c);

                              }

                              else if(a.equals("F") && (b.equals("03")))

                              {System.out.println("PMI");}

                              else if (a.equals("E"))

                              {

                              System.out.println("FAB");

                              }

                              else if (a.equals("X"))

                              {

                                        System.out.println("MIX");

                              }

                              else

                                                  {

                                        System.out.println("NA");

                                                  }

          }}

Hi Sankar,

Simply replace each occurrence of System.out.println("SOMETHING") with result.addValue("SOMETHING") and it should work as expected.

Hope this helps,
Greg

Clarifying your questions.

System.out.println is used to write the output on the console ie. input output device. So you use in the eclipse to show the values during runtime. Similary in UDF you can write the output as log traces as mentioned on the above reply.

If you want to provide the output of the UDF to the target, you need to add to the ResultList object. In UDF we reference the ResultList class with result instance variable.

result.addValue("values that needs to be added");

System.out.println wil not work in UDF's.

try the below code which will add the message in the log:

container.getTrace().addInfo("your message");
