[ERROR] org.apache.axis2.AxisFault: Mapping qname not fond for the package: oracle.sql

I implemented a SOAP service using Axis2 webservices which talks with the database and retrieve the values. I have used JDBC PreparedStatement, POJO java classes to generate the service. And list of fields in the table are name, id, designation, email, image. I inserted the values in the table. WSDL generated perfectly and able to see the values when I hit the service without of image field value (image =null). When I add the BLOB object to image in the table, then its giving databinding error as shown below.

Below insert statement is working fine:

insert into EMPINFO (EMP_NAME, EMP_ID, DESIGNATION, EMAIL_ID, IMAGE) values ('Ravi',1205,'Lead','ravivarma434@gmail.com',NULL);

Below insert statement giving binding error:

insert into EMPINFO (EMP_NAME, EMP_ID, DESIGNATION, EMAIL_ID, IMAGE) values ('Ravi',1205,'Lead','ravivarma434@gmail.com',to_blob(rawtohex('C:/Users/ravi.gandla/Desktop/EmpolyeeData/ravi.jpg')));

====================================================================
Java code part of the service is here:

public EmpData getEmpData(int empid) {
Connection conn = (Connection) MessageContext.getCurrentMessageContext().getProperty(DBServiceLifeCycle.DB_CONNECTION);
if(conn !=null) {
String SQL = "SELECT EMP_NAME, EMP_ID, DESIGNATION,EMAIL_ID, IMAGE FROM EMPINFO WHERE EMP_ID=?";
try {
PreparedStatement statement = conn.prepareStatement(SQL);
statement.setInt(1, empid);
ResultSet result = statement.executeQuery();
if (result.next())

{ EmpData empdata = new EmpData(); empdata.setEmpname(result.getString("EMP_NAME")); empdata.setEmpid((int)result.getInt("EMP_ID")); empdata.setDesignation(result.getString("DESIGNATION")); empdata.setImage(result.getBlob("EMP_IMAGE")); return empdata; }

} catch (SQLException e)

{ e.printStackTrace(); }

}
return null;
