Can't access User type using Synonyms/Grant

Question

Hi,
We have a Stored Proc and it accepts a usertype. We are sending info from Java using JDBC and trying to get the results back. If I use the owner of the schema for connection it works fine. If I use a different schema user which has synonyms and grant access to the storeproc and userobject program does not work. Here is the stripped down code. If any one faced this problem please respond to [email protected].
In the program I used QStore_user as user. QStore_user has Synonyms for USERTABLE, GET_NEXT_ID. Owner of these objects is QSTORE_OWNER. QSTORE_OWNER provided Grant 'Execute' to both of these for QSTORE_USER. If I change the java code to use QSTORE_OWNER it works fine.
Java Sample Program
====================
* This sample can be used to check the JDBC installation.
* Just run it and provide the connect information.
// You need to import the java.sql package to use JDBC
import java.sql.*;
import oracle.sql.*;
import oracle.jdbc.driver.*;
import oracle.jdbc.dbaccess.*;
// We import java.io to be able to read from the command line
import java.io.*;
class JdbcArrayCheckup
public static void main(String args[])
throws SQLException, IOException
// Load the Oracle JDBC driver
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
System.out.print("Connecting to the database...");
System.out.flush();
System.out.println("Connecting...");
Connection conn = DriverManager.getConnection
("jdbc:oracle:thin:@DKING-W2K:1521:WASDB", "qstore_user", "qstore_user");
System.out.println("connected.");
Object[] elements = {"Sasi","Mahesh","Deepak"};
String currentName = "Sasi";
ArrayDescriptor arrayDesc = ArrayDescriptor.createDescriptor("USERTABLE", conn);
     System.out.println("Got Array Descriptor");
     oracle.sql.ARRAY inp_array = new oracle.sql.ARRAY(arrayDesc,conn,elements);
     System.out.println("inp_array = " + inp_array);
// Create a Callable statement
     CallableStatement callStmt = conn.prepareCall("{? = call GET_NEXT_ID(?,?)}");
     System.out.println("created callable statement");
     // Call setArray to set input array
     callStmt.setArray(2,inp_array);
     System.out.println("set Array done for User ID array");
     callStmt.setString(3,currentName);
     System.out.println("set String done for Policy ID");
     callStmt.registerOutParameter(1,Types.VARCHAR);
     System.out.println("registered out Parameters");
     // Execute the query
     ResultSet rset = callStmt.executeQuery();
     System.out.println("executed query");
     String userID = callStmt.getString(1);
     System.out.println("after getting next assigned ID = " + userID);
     // close the result set, the statement and connect
rset.close();
callStmt.close();
conn.close();
System.out.println("Your JDBC installation is correct.");
Database Temp Function
======================
function GET_NEXT_ID (input_userid_list USERTABLE,
     input_policy_id varchar2
return VARCHAR2
     is
     counter NUMBER;
     return_user_id varchar2(30);
     /* UserTable is defined as follows -
     create or replace type usertable as table of varchar2(30);
     BEGIN
          for counter in 1..input_userid_list.COUNT LOOP
               dbms_output.put_line('tempuser id = ' || input_userid_list(counter) );
          end loop;
          dbms_output.put_line('out of the loop');
          return_user_id := 'Mahesh';
          return return_user_id;
END GET_NEXT_ID;

Answer 1

Might be possible that the usernmae & password you are using is not working on the route ... make sure that you are using correct username & password .... if not then reset the router so that the password also gets resetted & you can use Admin password without any username ...
Once resetted you need to reconfigure the router ... .& open the port 8080 for remote access ....
