Regarding splitting udf

Hi Experts ,

               i had requirement where i am getting multiple emails seperated by the delimiter ; so i need to split this based on delimiter i have used the following java code but i am getting the error

Execution type is all values of context

for(int i=0;i<Email;length++)

{

string token[]=Email[i].split(';' )

Email.addValue(token[0]);

Email.addValue(token[1]);

}

Thanks in advance
