Java語言-java.sql.SQLException：ORA-06550

Question

美好的一天！

我正在使用JSF 2.1 Primefaces 3.5 Glassfish 3.2.1

public class UserListProvider extends DBConnectionPool{

    private List sortList;
    private String whereClause;
    private List fieldList;

private void getUserList() {
        List userList = new ArrayList();
        UserBean users = null;
        ResultSetMetaData rsmd = null;

        try {
            super.initializeConnection();
            conn.setAutoCommit(false);
            String sortString = createSortStmt();
            super.cs = super.conn.prepareCall("{call ROCWEB.USERLIST_DATAPROV(?,?,?)}");
            super.cs.setString(1, whereClause);
            super.cs.setString(2, sortString);
            super.cs.registerOutParameter(3, OracleTypes.CURSOR);
            super.cs.execute();

            super.rs = (ResultSet) super.cs.getObject(3);

            //getting the columns
            rsmd = super.rs.getMetaData();
            setFieldList(new ArrayList());
            for (int i = 0; i < rsmd.getColumnCount(); i++) {
                getFieldList().add(rsmd.getColumnLabel(i + 1));
            }

            while (super.rs.next()) {
                users = new UserBean();
                users.setFirstName(rs.getString("firstname"));
                users.setLastName(rs.getString("lastname"));
                users.setPassword(rs.getString("password"));
                users.setEmail(rs.getString("email"));
                users.setUsername(rs.getString("username"));
                users.setUsername(rs.getString("username"));
                users.setUserId(rs.getLong("user_id"));
                userList.add(users);
                users = null;
            }
            conn.commit();
        } catch (Exception ex) {
            ex.printStackTrace();
            try {
                if (conn != null) {
                    conn.rollback();
                }
            } catch (SQLException sqle) {
                System.out.println(sqle.getMessage());
            }
        } finally {
            super.closeAll();
        }
        if (userList.isEmpty()) {
            userList.add(new UserBean());
        }
        this.setList(userList);
    }
}
public class DBConnectionPool extends BasePageBean {

public Connection conn;
public ResultSet rs;
public PreparedStatement ps;
public CallableStatement cs;
private String whereClause = "";
private String sortClause = "";
        public void initializeConnection() {
                    try {
                        Context jdbcContext = new InitialContext();
                        DataSource ds = ((DataSource) jdbcContext.lookup("jdbc/rocjndi"));
                        DataSource dsCOP = ((DataSource) jdbcContext.lookup("jdbc/COP"));
                        if(this.conn != null){
                            this.closeAll();
                        }
                        this.conn = null;
                        this.conn = ds.getConnection();
                        this.conn =dsCOP.getConnection();
                        this.conn.setAutoCommit(false);
                    } catch (Exception e) {
                        e.printStackTrace();
                        System.out.println(this.getClass() + " - " + e.toString());
                    }
                }

}

當使用上述方法（initializeConnection）使用glassfish應用服務器連接數據庫時。 我在下面收到此錯誤。 如果我使用的是一個數據源，則可以使用，但是我需要兩個數據源。 當在initializeConnection方法中使用兩個DataSource時，UserListProvider類在下面產生錯誤。

Please help me to solve this. 



Thank you and More Power!

Answer 1

我會說問題出在這里：

                   this.conn = ds.getConnection();
                   this.conn =dsCOP.getConnection();

在這兩行之后，字段this.conn包含“ COP”數據庫連接。 ds.getConnection()返回的與“ ROC”數據庫的連接已丟失。

我可以理解您要使用兩個數據源，但是不能將它們都分配給同一字段！ 您將需要創建兩個單獨的字段，每個連接一個，並將連接分配給不同的字段。 例如：

                   this.connROC = ds.getConnection();
                   this.connCOP = dsCOP.getConnection();

從錯誤消息中可以明顯看出，您現在已經添加了您正在使用“ COP”連接對“ ROC”數據庫運行查詢。 毫不奇怪，這失敗了，因為“ COP”數據庫中不存在ROCWEB軟件包。
