changed to this(where format changed):
			{
				String chr = st.nextToken();
				String cmd = "UPDATE characters SET x = -84318, y = 244579, z = -3730 WHERE char_name = '"+chr+"'";	//fixed
				java.sql.Connection connection = null;
				try

					PreparedStatement statement = connection.prepareStatement(cmd);

					statement.close();

					connection = L2DatabaseFactory.getInstance().getConnection();
					statement = connection.prepareStatement("SELECT obj_id FROM characters where char_name = '"+chr+"'");	//fixed
					ResultSet rset = statement.executeQuery();

					
					int obj_id = rset.getInt(1);
					
					rset.close();
					statement.close();

tried this (while added):

				String cmd = "UPDATE characters SET x = -84318, y = 244579, z = -3730 WHERE char_name = '"+chr+"'";
				java.sql.Connection connection = null;
				try
				{
					connection = L2DatabaseFactory.getInstance().getConnection();
					PreparedStatement statement = connection.prepareStatement(cmd);
					statement.execute();
					statement.close();

					connection = L2DatabaseFactory.getInstance().getConnection();
					statement = connection.prepareStatement("SELECT obj_id FROM characters where char_name = '"+chr+"'");
					ResultSet rset = statement.executeQuery();
					while (rset.next()) {		//added this to test
					
					int obj_id = rset.getInt(1);
					
					rset.close();
					statement.close();
					
					connection = L2DatabaseFactory.getInstance().getConnection();
					statement = connection.prepareStatement("DELETE FROM character_shortcuts WHERE char_obj_id="+obj_id);
