StringIndexOutOfBoundException In UDF in mapping

Question

Hi ,
I have a UDF via which I am taking the input string and for every 132 characters of input string I split in show it in a different line of an idoc.
It is working fine for 2 lines .However when I get 3 lines  i.e. anything more then
395 characters I get this error
StringIndexOutOfBoundException
following is the code I am using in the udf.
public void deriveTEXT(String[] a,ResultList result,Container container){
for(int i=0;i<a.length;i++)
            int len=a<i>.length();
            int variant=132;
            int count=len/variant;
            int initial=0;
            int fin=0;
            if(count>=1)
                        fin=variant;
            else
                        fin=a<i>.length();
            for(int j=0;j<count;j++)
                        result.addValue(a<i>.substring(initial,fin));
                        initial=fin;
                        fin=2*fin;
            result.addValue(a<i>.substring(initial,a<i>.length()));
            if(i<a.length-1)
            result.addContextChange();
Kindly help.

Hi ,
Just small change required .
your code
for(int j=0;j<count;j++)
result.addValue(a.substring(initial,fin));
initial=fin;
fin=2*fin;
Change  it to
for(int j=0;j<count;j++)
result.addValue(a.substring(initial,fin));
initial=fin;
fin=fin+132;
Thanks ,
