Oracle Wallet config - oracle

Question

I am trying to configure oracle wallet in my spring app. below is the error:
Cause: org.springframework.jdbc.CannotGetJdbcConnectionException:
Could not get JDBC Connection; nested exception is
java.sql.SQLRecoverableException: IO Error: Unknown host specified ]
I put all configuration files(cwallet.sso, ewallet.p12) & jars() & setup tnsnames.ora
Below is the code.
private DriverManagerDataSource getDriverManagerDataSource(final String driver,
final String url,
final String username,
final String password) {
final DriverManagerDataSource dataSource = new DriverManagerDataSource();
Properties props = new Properties();
props.put("oracle.net.wallet_location", pathToWallet);
dataSource.setConnectionProperties(props);
dataSource.setDriverClassName(driver);
dataSource.setUrl(url);
//dataSource.setUsername(username);
//dataSource.setPassword(password);
return dataSource;
}

Malik,
The example program does not have complete information.
I think In your program if you replace below code
Properties props = new Properties();
props.put("oracle.net.wallet_location", pathToWallet);
with
System.setProperty("oracle.net.tns_admin", "**tnsnames.ora_file_location**");
System.setProperty("oracle.net.wallet_location", "**Oracle_Wallet_Location**");
It should resolve your issue.
I have setup my oracle wallet by following below steps.
cd %ORACLE_HOME%\BIN
mkstore -wrl D:\oraclewallet\wallet -create (Provide wallet password)
mkstore -wrl D:\oraclewallet\wallet -createCredential **Tns_Entry_Name** **Schema_Name** **Password**
Entries in %ORACLE_HOME%\NETWORK\admin\sqlnet.ora
WALLET_LOCATION =(SOURCE=(METHOD=FILE)(METHOD_DATA=(DIRECTORY=**Oracle_Wallet_Location**)))
SQLNET.WALLET_OVERRIDE = TRUE
Here you should be able to connect to db using sqlplus
sqlplus /#**Tns_Entry_Name**
Below java run time arguments should be set while running the java program
-Doracle.net.tns_admin=**%ORACLE_HOME%\NETWORK\ADMIN**
-Doracle.net.wallet_location=**Oracle_Wallet_Location**
Otherwise we can set during runtime as
System.setProperty("oracle.net.tns_admin", "%ORACLE_HOME%\\NETWORK\\ADMIN");
System.setProperty("oracle.net.wallet_location", "Oracle_Wallet_Location");
Now for getting db connection you should use the database url as
jdbc:oracle:thin:/#**tns_entry_name**
Sample Program Test Result Oracle Wallet
Make sure you have below jars in classpath
ojdbc6.jar
oraclepki.jar
osdt_cert.jar
osdt_core.jar
Sample code to test
package datasourcetest;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import javax.sql.DataSource;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
public class DataSourceConnectionExample {
private static final String DRIVER_CLASS_NAME = "oracle.jdbc.driver.OracleDriver";
private static final String URL = "jdbc:oracle:thin:/#**tns_entry_name**";
public static void main(String[] args) throws SQLException {
System.setProperty("oracle.net.tns_admin", "**%ORACLE_HOME%\\NETWORK\\ADMIN**");
System.setProperty("oracle.net.wallet_location", "**Oracle_Wallet_Location**");
Connection conn = getDataSource().getConnection();
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT 'test' name FROM dual");
while (rs.next()) {
System.out.println(rs.getString("name"));
}
}
public static DataSource getDataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(DRIVER_CLASS_NAME);
dataSource.setUrl(URL);
return dataSource;
}
}
