Title: No signature Match error

Hi,

I would like to know if there is a solution to the following scenario....

java web service method with signature getFundHoldingTransactionss(int aUnitInvestor, string aUnitFund, string aUnitType, string aUnitClass, DateSearchCriteria aDateSearchCriteria)  is not invoked if client passes null objects for any of the objects.

In the case that the first String is null.e.g., getFundHoldingTransactionss(1, null, "", "", new DateSearchCriteria(1,null,1))  , the error message is

Exception while handling service request: getFundHoldingTransactions(int, java.lang.String, java.lang.String, com.rbc.DateSearchCriteria) -- no signature match

In the case that the DateSearchCriteria is null, e.g., getFundHoldingTransactionss(1, "", "", "", null)  the error message is

Exception while handling service request: getFundHoldingTransactions(int,java.lang.String,java.lang.String,java.lang.String) -- no signature match

 
The client is a .Net client and the proxy is correct in that it calls the web service method with the correct number of parameters.  It looks to me like it is failing in the RPC router servlet.

Can anyone shed any  light on this problem? 

Thanks in advance,

Aedemar
