我在使用Oracle Wallet作为密码存储将我的Java应用程序连接到Oracle数据库时遇到了问题。

为了隔离问题，我创建了一个小的主类，如下所示：

public static void main(String[] args) {
Connection conn;
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
System.setProperty("oracle.net.tns_admin", "c:\tns");
OracleDataSource ds = new OracleDataSource();
Properties props = new Properties();
System.setProperty("oracle.net.wallet_location", "c:/wallet2");

ds.setConnectionProperties(props);
ds.setURL("jdbc:oracle:thin:/@XE2");
Provider p;
p = new OraclePKIProvider();
Security.insertProviderAt(p, 3);
conn = ds.getConnection();

} catch (SQLException ex) {
Logger.getLogger(main.class.getName()).log(Level.SEVERE, null, ex);

} catch (ClassNotFoundException ex) {
Logger.getLogger(main.class.getName()).log(Level.SEVERE, null, ex);
}

在目录c：\tns中，我有以下文件：

sqlnet.ora
tnsnames.ora

这是sqlnet.ora的列表

SQLNET.AUTHENTICATION_SERVICES = (NTS)
names.directory_path = TNSNAMES
SQLNET.WALLET_OVERRIDE = TRUE

# WALLET_LOCATION = (SOURCE=(METHOD=FILE)METHOD_DATA=(DIRECTORY=c:wallet))

WALLET_LOCATION = (SOURCE=(METHOD=FILE)(METHOD_DATA=(DIRECTORY=c:/wallet)))

对于tnsname来说

...
XE2 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
    )
  )

在c：\wallet2中有以下文件：

cwallet.sso
ewallet.p12

该文件以前是用orapki生成的，我的条目名为xe2，具有正确的凭据。当我运行代码时，我得到以下异常

Could not open wallet. java.io.IOException: Could not open wallet. Check password

启用Oracle跟踪后，我可以看到以下几行：

mar 02, 2017 3:57:00 PM oracle.jdbc.driver.DatabaseError findMessage
TRACE_30:          Enter: "ORA-17168", java.io.IOException: Could not open wallet. java.io.IOException: Could not open wallet. Check password
mar 02, 2017 3:57:00 PM oracle.jdbc.driver.Message11 msg
TRACE_30: 72B6CBCC Enter: "ORA-17168", java.io.IOException: Could not open wallet. java.io.IOException: Could not open wallet. Check password
mar 02, 2017 3:57:00 PM oracle.jdbc.driver.Message11 msg
TRACE_30: 72B6CBCC Exit [0.066509ms]

和

mar 02, 2017 3:57:00 PM oracle.jdbc.driver.PhysicalConnection getSecretStoreCredentials
GRAVE:          Throwing SQLException: 168java.io.IOException: Could not open wallet. java.io.IOException: Could not open wallet. Check password

有人能帮我吗？谢谢你的阅读。河
