Get Sequence Next Value in OAF

I posted Get Sequence Next Value in ADF.
Today I will create function that returns sequence next value in OAF framework.

We pass sequence name to method and it returns next value of sequence

 public Number getSequenceValue(String sequenceName) {  
     Number sequenceValue;  
     if (sequenceName != null && !"".equanls(sequenceName)) {  
       OADBTransaction transaction = getOADBTransaction();  
       sequenceValue = transaction.getSequenceValue(sequenceName);  
     }  
     return sequenceValue;  
   }  

Thanks
