UDF issue about record counter

Question

Hi gurus,
i want to create the auto-increasing counter for the records in my message mapping.But during my testing,the sequence number always pops up "1" which means it don't calculate based on the cache value. The code as below:
=========================================================================================
public String Counter(Container container){
GlobalContainer gcontainer =  container.getGlobalContainer();
     Object o = gcontainer.getParameter("counter");
      Integer iSeq ;
      if(o == null)
           iSeq = new Integer(1);
      }else
           iSeq = (Integer)o;
           iSeq = new Integer(iSeq.intValue() + 1);
           gcontainer.setParameter("counter",iSeq);
      return iSeq.toString();
==========================================================================================
can anyone shed light on this?
Thanks in advance.

Hi rajesh
anothr smart option.
in meesage mapping editor under function tab
add the below code
Under Attributes and Methods  Integer iSeq ;
Under init   iSeq = new Integer(0);
Then UDF:
public String Counter(Container container){
iSeq = iSeq+1;
return iSeq.toString();
