Hi,

You can try the following mapping

             marks ------------>removeContexts------------>UDF-------->target field

The UDF is as shown below ( use advanced UDF of type "context")

public void totalMarks(String a[],ResultList result,Container container)
	{
		String t="";
		try
		{
			int i,sum=0;
			for(i=0;i<a.length;++i)
			{
				sum=sum+ new Integer(a<i>).intValue();
			}
			t=new Integer(sum).toString();
		}
		catch(Exception e)
		{
			e.printStackTrace();
		}
		result.addValue(t);
	}

Hope this helps.

Hi,

I guess this will not work with Graphical mapping..I m not Sure abt it

But by writing simple UDF you can achieve this,

Execution type -- All values of Queue

marks as firstparameter

int mark1 =0;

for(int i =0;i<marks.length;i++)

{

mark1 = mark1+marks<i>;

String s = Integer.toString(mark1);

}

resultset.addValue(s);

Try this Once

You can use Sum function. You will need to handle the context of input data.
