substring to get last values

[naveen_chichili]

Dear All,

I have a mapping where I am using an udf for substring in PI 7.3.

I am using below udf code for substring

-----------------

String variable1="";

if (variable1!=null)

   output1 = variable1.substring(6, variable1.length());

return output1;

---------------

if the same udf is used for the other field it is not working...

-------------------
String output1="";

if (output!=null)

   output1 = output.substring(12, output.length());

return output1;

---------------

Also I tried creating function libraries also but no luck..

could any one suggest me...

Thanks and Regards,

Naveen.

Hi naveen,

You mean you need a generic udf to use for two of the fields you have mentioned. Is tat your requirement? In tat case pass the numbers 6 and 12 as constants and use the below generic udf.

public String findSubstring(String input, int Count, Container container) throws StreamTransformationException

{

String output="";

if(input!= null)

  output = input.substring(count,input.length());

else

  output="";

return output;

}

Hi,

You may want to refer to these links:

Also if the input say inp1 is String, try   as:

if (!inp1.equals("null"))

This is pretty simple requirement. Please share your code.

@Anupam:  I think it's typo error. You check not null twice in the line 5.

Hi Baskar,

                Thank you for pointing out the typing error. Corrected the same.

Hi Naveen,

                   Made little changes to your code. Please try the code given below

public static String returnStr(String output)
 {
  String output1="";
  int l;
  if (output!=null  && !output.equals("") )
  {
     l=output.length();
     if(l>=12)
     {
      output1 = output.substring(12,l);
     }    
     
  }   
   
  return output1;
 }

Regards

Hello Naveen,

Please check the first UDF, here variable1 is an argument string, please try to change the first code line: String variable1="";  to String output1="";

-----------------

String output1="";

if (variable1!=null)

   output1 = variable1.substring(6, variable1.length());

return output1;

-----------------

I guees the problem is with the length is less 12.
