Hi,

Alternate way

src------------->
                   textfunction(Concat)---->tgt
constant------>

hi,

you can use predefined functions CONCAT to obtain u r functionality. no need to use UDF for this.

Thanks,

Hi,

use cache parameter - value

public String concat(String a,Container container)
{
   //write your code here
 String value = "";//inser the string which u want to add to element
 String target = " ";
 target = a + value;
 return target;
}

source->udf(concat)->tgt

Hello Malini,

Thank you for your reply...

But I cannt hard code the source element,

I have only element and this will be populated at runtime and the value of the element needs to be sent to udf while using mapping
