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

Question

Good day!

Im using 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());
                    }
                }

}

When using method above(initializeConnection) for connecting to DB using glassfish app server. I got this errors below. If I'm using one datasource it is working but I need two data source. UserListProvider class produce an error below when using two DataSource in initializeConnection method.

StackTrace;

Please help me to solve this. 



Thank you and More Power!

Answer 1

I would say that the problem is here:

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

After these two lines, the field this.conn contains the 'COP' database connection. The connection to the 'ROC' database that was returned by ds.getConnection() has been lost.

I can understand you wanting to use two datasources, but you can't assign them both to the same field! You will need to create two separate fields, one for each connection, and assign the connections to different fields. For example:

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

It seems clear to me from the error message that you have now added that you are using the 'COP' connection to run a query against the 'ROC' database. Unsurprisingly, this fails, as the ROCWEB package doesn't exist in the 'COP' database.
