Here's how to get the real resultset from a the proxied class:
 

public Object getResult(ResultGetter getter) throws SQLException {
  ResultSet rs = getter.getResultSet();
  if (Proxy.isProxyClass(rs.getClass())) {
    InvocationHandler ih = Proxy. getInvocationHandler(rs);
    if (ih instanceof ResultSetLogProxy) {
      ResultSet realResultSet = ((ResultSetLogProxy) ih).getRs();
      // do something here...
    }
  }
}

It's ugly - but it works.

Jeff,

I did read your posting at http://www.mail-archive.com/user-java@ibatis.apache.org/msg06898.html  already before sending this question. I could not understand how/where do I modify the code to consider proxy class.

My getOpaqueValue() displays ResultSet class is: $Proxy2, not ResultSetLogProxy.

The program DOES WORK if I turn off logging.

I tried something like this:

  public Object getResult(ResultGetter getter) throws SQLException {
    //    if (getter.getResultSet() instanceof OracleResultSet) {
            OPAQUE opaqueValue = getOpaqueValue(getter);
            if (opaqueValue != null) {
                XMLType xmlResult = XMLType.createXML (opaqueValue);
                return xmlResult.getDOM();
            } else {
                return null;
            }
     //   } else {
      //      throw new UnsupportedOperationException("XMLType mapping only supported for Oracle RDBMS");
      //  }
    }


    private OPAQUE getOpaqueValue(ResultGetter getter) throws SQLException {

         
          java.sql.ResultSet rs = getter.getResultSet();
          System.out.println("ResultSet class is: " + rs.getClass());
   //       ResultSetLogProxy rsProx =  (ResultSetLogProxy)rs;
          OracleResultSet ors = (OracleResultSet)ResultSetLogProxy.newInstance(rs);         //--- THROWS ClassCastException
          OPAQUE op = null;
          if (getter.getColumnName() != null) {
              op = ors.getOPAQUE(getter.getColumnName());
          } else {
              op = ors.getOPAQUE(getter.getColumnIndex());
          }
          return op;
      }


Thanks

Re: Exception "XMLType mapping only supported for Oracle RDBMS"




The code in the wiki article does not take into account the fact that iBATIS logging changes the normal classes to proxy classes.  First thing to do is turn off logging to see it will work.  Second thing, the code must be modified to account for the proxy class if logging is enabled (add another instanceof check for the proxy class, then unwind the embedded "real" class).

I am using code as directed in this url:

http://opensource.atlassian.com/confluence/oss/display/IBATIS/XMLTypeHandlerCallback.java

It throw UnsupportedOperationException("XMLType mapping only supported for Oracle RDBMS");

I have logger set to DEBUG  mode.

I tried displaying class from ResultSet like :

        java.sql.ResultSet rs = getter.getResultSet();
        System.out.println("ResultSet class is: " + rs.getClass());

The cosole displays

[20 Dec 2007 15:15:05] DEBUG [PreparedStatement] {pstm-100001} Executing Statement:         SELECT OTM, SEQUENCE, MESSAGETYPE, MESSAGEID, STATUS, PROCESSED_TIME, CREATED     FROM OTM_XML

ResultSet class is: class $Proxy2

I am using JDeveloper 10.1.3.1

What should I change in my code to make it working?

Thanks
