Not able to get the data on the page

Question

hi,
I tried brining the data on the JSP page. I am passing the parameters to a PL/SQL procedure. but I am not getting any data or error. can anyone helpme how to proceed further I am retreving the page parameters that are passed to the JSP page like this.
<%
PortletRenderRequest portletRequest = (PortletRenderRequest)request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
RenderContext rc = portletRequest.getRenderContext();
PortletDefinition pd = portletRequest.getPortletInstance().getPortletDefinition();
%>
I am getting the page parameters. but I am not able to get any result on the page.
while I am using the same code to get the data on another JSP page I am getting the data except I am not retreving the page parameters.
I am using the code like this to pass the parameters to the procedure.
OracleConnection conn__OCI      = cpool.getProxyConnection(OracleOCIConnectionPool.PROXYTYPE_USER_NAME, proxUserProp);
                              cstmt = conn__OCI.prepareCall ("begin test.test1( ?,?,?,?,? ); end;");
                              cstmt.setString(2, cnumb);
                              cstmt.setString(3, cperiod);
                              cstmt.setInt(4, retStrC);
                              cstmt.setString(5, retStr3);
                              cstmt.registerOutParameter (4, Types.NUMERIC);
                              cstmt.registerOutParameter (5, Types.VARCHAR);
                              cstmt.registerOutParameter(1, OracleTypes.CURSOR);
                              cstmt.execute();
                              retStrC = cstmt.getInt (4);
                              retStr3 = cstmt.getString (5);
                              retStr = "<tr class=OraDataText><td>  " + retStrC + "</td></tr>";
                              retStr = retStr + "<tr class=OraDataText><td>  " + retStr3 + "</td></tr>";
                              if ( retStrC == -1 )                    { ALLretStr = ALLretStr + retStr; }
                              else
                                   cursor = ((OracleCallableStatement)cstmt).getCursor(1);
                                   while (cursor.next ())
                                             if (spacerLine >= 2)
                                                  ALLretStr = ALLretStr + "<tr><td colspan=5 height=1 <div id=ssubLine> <div id=ssubLinet></div> </div> </td></tr>";
                                             ALLretStr = ALLretStr + "<tr class=smmjWipAltText><td ALIGN=LEFT>" + cursor.getString(1) + "</td><td ALIGN=CENTER>" + cursor.getInt(2) + "</td><td ALIGN=CENTER>" + cursor.getString(3) + "</td><td ALIGN=CENTER>" + cursor.getString(4) + "</td><td ALIGN=RIGHT>" + cursor.getString(5) + "</td></tr>";
                                             spacerLine++;
                              }
