Error in Extended Receiver Determination

Hello Experts,

We are working on a scenario where, we are using Extended Receiver Determination.

In this reveiver determination mapping we are doing JDBC lookup and some receivers are determined on that basis.

Also, we have a default receiver in mapping.

We are using: SAP PO 7.4 SP 7

We are getting below error while testing from WSnavigator/SOAP UI, but mapping works when we test it in ESR.

Error:

<s:SystemError xmlns:s='http://sap.com/xi/WebService/xi2.0'>

          <context>XIAdapter</context>

          <code>ADAPTER.JAVA_EXCEPTION</code>
