method is undefined for the type error in tJavaRow

[TY3]

I'm working on a job that reads the IMEI number (14 or 15 digits) of a mobile phone and converts it to a 15 digit number in case the input is of 14 digits. Used tJavaRow to implement this algorithm and given below is the code. When run, this job fails with the error; device_imei_conversion being the name of the Talend job. Can someone help with this error?

Detail Message: The method sumOfDigits(int) is undefined for the type device_imei_conversion

// Calculate sum of digits for a number

public static int sumOfDigits(int number)

{

      int sum=0;

     while(number > 0)

      {

            sum += number%10;//get the modulus and add it to the running sum

number = number/10;//get the first digit of a number by downcasting; number is int datatype so it removes anything after decimal point

}

return sum;

}

if (input_row.IMEI.length() = 14) {

int sum = 0;

for(int i = 13;i>=0;i=i-1)//loop through all 14 digits in an IMEI

{

            String sDigit = input_row.IMEI.substring(i,i+1);//get each digit of IMEI, starting from the right

            int digit = Integer.valueOf(sDigit);

            if(i%2==0)//way to identify every other second digit from the right

            {

                  sum = sum + digit;

            }else

            {

                  sum = sum + sumOfDigits(digit*2);

            }

}

sum = sum * 9;// multiply the total sum by 9

String modvalue = String.valueOf(sum%10); // Return check digit

output_row.IMEI = input_row.IMEI+modvalue;

}

else

{

output_row.IMEI = input_row.IMEI;

}

I don't think you can have a function inside of your tjavarow.  Put your function:

// Calculate sum of digits for a number

public static int sumOfDigits(int number)

in the metadata/code area.  Test it to make sure it's working, and then call that from your tjavarow.

Thanks for your response. Didn't know tJavaRow doesn't support functions. As a workaround, I wrote the same code as part of my "main" instead of a function.
