I am not able to get the replayable datasource (Code is attached below).
PoolDataSource pds = PoolDataSourceFactory.getPoolDataSource();
pds.setConnectionFactoryClassName("oracle.jdbc.replay.OracleDataSourceImpl");
System.out.println("connection factory set");
String URL = "jdbc:oracle:thin:#(DESCRIPTION = (TRANSPORT_CONNECT_TIMEOUT=3) (RETRY_COUNT=20)(FAILOVER=ON) " +
" (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)) (CONNECT_DATA = " +
" (SERVER = DEDICATED) (SERVICE_NAME=orcl)))";
System.out.println("Using URL\n" + URL);
pds.setURL(URL);
pds.setUser("system");
pds.setPassword("oracle");
pds.setInitialPoolSize(10);
pds.setMinPoolSize(10);
pds.setMaxPoolSize(20);
pds.setConnectionWaitTimeout(10);
// RAC Features
pds.setConnectionPoolName("Application Continuity Pool");
pds.setFastConnectionFailoverEnabled(true);
System.out.println("pool configured, trying to get a connection");
Connection conn = null;
try{
conn = pds.getConnection();
}catch(Exception e){
e.printStackTrace();
}
if (conn == null || !((ValidConnection) conn).isValid()) {
System.out.println("connection is not valid");
throw new Exception ("invalid connection obtained from the pool");
}
if ( conn instanceof oracle.jdbc.replay.ReplayableConnection ) {
System.out.println("got a replay data source");
} else {
System.out.println("this is not a replay data source. Why not?");
}
Below is the System Prints I am getting out from above code, which show the connection instance is not of replayable type.
connection factory set Using URL jdbc:oracle:thin:#(DESCRIPTION =
(TRANSPORT_CONNECT_TIMEOUT=3) (RETRY_COUNT=20)(FAILOVER=ON) (ADDRESS

to get a connection this is not a replay data source. Why not?
I got the code from below site and modified a bit to add threads and simulate AC. But I am unable to get a replayable datasource.

Please make sure you have oracle.jdbc.replay.OracleDataSourceImpl in your classpath, in other words, please make sure you have the 12.1.0.2 JDBC driver in your classpath.

I am putting online an old web application I had running like 3 years ago.
Back then everything worked and Paypal's ExpressCheckout was set perfectly.
I really cannot remember what I was doing back then but now I put my app on Windows Azure. My app is written in ASP.NET MVC5.
The following piece of code might look familiar for those of you who implemented Paypal inside your apps and its probably taken from Paypal's documentation and used for posing to Paypal's server:
/// <summary>
/// HttpCall: The main method that is used for all API calls
/// </summary>
/// <param name="NvpRequest"></param>
/// <returns></returns>
public string HttpCall(string NvpRequest) //CallNvpServer
{
string url = pendpointurl;
//To Add the credentials from the profile
string strPost = NvpRequest + "&" + buildCredentialsNVPString();
strPost = strPost + "&BUTTONSOURCE=" + HttpUtility.UrlEncode(BNCode);
HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create(url);
objRequest.Timeout = Timeout;
objRequest.Method = "POST";
objRequest.ContentLength = strPost.Length;
objRequest.ContentType = "application/x-www-form-urlencoded";
try
{
using (StreamWriter myWriter = new StreamWriter(objRequest.GetRequestStream()))
{
myWriter.Write(strPost, 0, strPost.Length);
}
}
catch (Exception e)
{
CommonFuncs.Log(MyGlobals.LOG_FILE_DO_EXPRESS_CHECKOUT, e.Message);
return null;
/*
if (log.IsFatalEnabled)
{
log.Fatal(e.Message, this);
}*/
}
//Retrieve the Response returned from the NVP API call to PayPal
HttpWebResponse objResponse = (HttpWebResponse)objRequest.GetResponse();
string result;
using (StreamReader sr = new StreamReader(objResponse.GetResponseStream()))
{
result = sr.ReadToEnd();
}
//Logging the response of the transaction
/* if (log.IsInfoEnabled)
{
log.Info("Result :" +
" Elapsed Time : " + (DateTime.Now - startDate).Milliseconds + " ms" +
result);
}
*/
return result;
}
Now, when I'm trying to POST (here)
using (StreamWriter myWriter = new StreamWriter(objRequest.GetRequestStream()))
{
myWriter.Write(strPost, 0, strPost.Length);
}
I am getting the following error message
The request was aborted: Could not create SSL/TLS secure channel.
Does it mean that I have to purchase an SSL certificate? or is there something I just need to tweek on Azure so it will work?
No need to purchase an SSL. But you can upgrade your certificate into SHA 256 and TLS 1.2. Refer to the link below.
https://www.paypal-knowledge.com/infocenter/index?page=content&id=FAQ1913
and
https://github.com/paypal/TLS-update
Thank you #PP_MTS_Steven.
I can't remember the source on SO which gave me the solution. However, all I did was to put this two lines of code:
ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;
// allows for validation of SSL conversations
ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };
Right here:
public string HttpCall(string NvpRequest) //CallNvpServer
{
string url = pendpointurl;
//To Add the credentials from the profile
string strPost = NvpRequest + "&" + buildCredentialsNVPString();
strPost = strPost + "&BUTTONSOURCE=" + HttpUtility.UrlEncode(BNCode);
ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;
// allows for validation of SSL conversations
ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };
HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create(url);
objRequest.Timeout = Timeout;
objRequest.Method = "POST";
objRequest.ContentLength = strPost.Length;
objRequest.ContentType = "application/x-www-form-urlencoded";
...
And things started working.
I have tried

I wish to fetch the list of all distinguised names (DNs) from LDAP server using JNDI. I am able to fetch the base DN using following code:
Hashtable<String,String> env = new Hashtable<String,String>();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://" + ldapServer + ":" + ldapPort);
env.put(Context.REFERRAL, "follow");
if(sslEnabled) {
env.put("java.naming.ldap.factory.socket", TrustAllSSLSocketFactory.class.getName());
}
// Create the LDAP context
LdapContext context = new InitialLdapContext(env, null);
String base = "";
String filter = "(objectclass=*)";
SearchControls controls = new SearchControls();
controls.setSearchScope(SearchControls.OBJECT_SCOPE);
// Search the directory for retrieving namingContexts attribute
// which contains all the base DNs values
NamingEnumeration<SearchResult> results = context.search(base, filter, controls);
List<String> namingContextsList = new ArrayList<String>();
// Process attributes
if(results.hasMore()) {
Attributes attrs = results.next().getAttributes();
if (attrs != null) {
Attribute namingContexts = attrs.get("namingContexts");
NamingEnumeration enumeration = namingContexts.getAll();
while(enumeration.hasMore()) {
namingContextsList.add((String) enumeration.next());
}
}
}
System.out.println(namingContextsList);
Could you please help in fetching all the possible DNs in similar manner or other?
Just change OBJECT_SCOPE to SUBTREE_SCOPE.
This is all documented, you know.
Following code works for me: (Note that you need to provide credentials to perform this operation and the attribute name is "distinguishedName")
String ldapServer = "192.168.0.11";
String ldapPort = "389";
String principal = "CN=user";
String password = "password";
Hashtable<String,String> environment = new Hashtable<String,String>();
environment.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
environment.put(Context.PROVIDER_URL, "ldap://" + ldapServer + ":" + ldapPort);
environment.put(Context.SECURITY_AUTHENTICATION, "simple");
environment.put(Context.SECURITY_PRINCIPAL, principal);
environment.put(Context.SECURITY_CREDENTIALS, password);
environment.put(Context.REFERRAL, "follow");
environment.put("com.sun.jndi.ldap.connect.pool", "true");
// Create the LDAP context
LdapContext context = new InitialLdapContext(environment, null);
String baseDN = "DC=domain,DC=com" // Put your base DN here
String filter = "(objectclass=*)";
SearchControls controls = new SearchControls();
controls.setSearchScope(SearchControls.SUBTREE_SCOPE);
//controls.setSearchScope(SearchControls.ONELEVEL_SCOPE); // Use this for first level DNs only
NamingEnumeration<SearchResult> results = context.search(baseDN, filter, controls);
List<String> searchDNsList = new ArrayList<String>();
try {
// Process attributes
while(results.hasMore()) {
Attributes attrs = results.next().getAttributes();
if (attrs != null) {
Attribute distinguisedNames = attrs.get("distinguishedName");
if(distinguisedNames != null) {
NamingEnumeration enumeration = distinguisedNames.getAll();
while(enumeration.hasMore()) {
String searchDN = (String) enumeration.next();
searchDNsList.add(searchDN);
}
}
}
}
} catch(Exception ex) {
ex.printStackTrace();
}
System.out.println(searchDNsList);
I want to connect to ldap over SSL using truststore file.
I'm using the following code:
private DirContext ctxtDir = null;
Attributes attributes = null;
ldap_server_url = "ldaps://" + getLdapHostName() + ":"
+ getPort() + "/";
ldap_base_dn = getBaseDn();
ldap_user = getLogin();
ldap_password = getPwd();
ldap_trust_store_file = "C:\\truststore.jks";
ldap_trust_store_pwd = getStoreJKSPwd();
// Set the parameters
env = new Hashtable<String, String>();
env.put(Context.INITIAL_CONTEXT_FACTORY, ldap_context_factory);
env.put(Context.PROVIDER_URL, ldap_server_url);
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, ldap_user);
env.put(Context.SECURITY_CREDENTIALS, ldap_password);
env.put(Context.SECURITY_PROTOCOL, "SSL");
// Set SSL parameters for Ldaps connection
System.setProperty("javax.net.ssl.trustStore", ldap_trust_store_file);
System.setProperty("javax.net.ssl.trustStorePassword",
ldap_trust_store_pwd);
// Try to establish the connection
try {
// create initial context
ctxtDir = new InitialDirContext(env);
attributes = getLdapattributes(ldap_base_dn);
if (null != attributes) {
isAvailable = true;
}
} catch (Exception e) {
isAvailable = false;
}
The problem is that i don't want to use the location of the truststore file, i want to use the inputstream (file content), is there any way to do that? like when using SSLContext to esbabish a https connection.
Unbound Ldap SDK is best latest LDAP API. It also offers SSLSocketFactory to establish SSL connection.
TrustAllTrustManager manager = new TrustAllTrustManager();
SSLUtil sslUtil = new SSLUtil(manager);
SSLSocketFactory socketFactory;
try {
socketFactory = sslUtil.createSSLSocketFactory("TLSv1");
}
catch (GeneralSecurityException e) {
throw new LDAPException(ResultCode.CANCELED, "An error occured while creating SSL socket factory.");
}
and use this socketFactory as
new RoundRobinServerSet(addressesArray, portsArray, socketFactory);
I'm now developing big government application with entity framework. at first i have one problem about enable SQL application role. with ado.net I'm using below code:
SqlCommand cmd = new SqlCommand("sys.sp_setapprole");
cmd.CommandType = CommandType.StoredProcedure;
cmd.Connection = _sqlConn;
SqlParameter paramAppRoleName = new SqlParameter();
paramAppRoleName.Direction = ParameterDirection.Input;
paramAppRoleName.ParameterName = "#rolename";
paramAppRoleName.Value = "AppRole";
cmd.Parameters.Add(paramAppRoleName);
SqlParameter paramAppRolePwd = new SqlParameter();
paramAppRolePwd.Direction = ParameterDirection.Input;
paramAppRolePwd.ParameterName = "#password";
paramAppRolePwd.Value = "123456";
cmd.Parameters.Add(paramAppRolePwd);
SqlParameter paramCreateCookie = new SqlParameter();
paramCreateCookie.Direction = ParameterDirection.Input;
paramCreateCookie.ParameterName = "#fCreateCookie";
paramCreateCookie.DbType = DbType.Boolean;
paramCreateCookie.Value = 1;
cmd.Parameters.Add(paramCreateCookie);
SqlParameter paramEncrypt = new SqlParameter();
paramEncrypt.Direction = ParameterDirection.Input;
paramEncrypt.ParameterName = "#encrypt";
paramEncrypt.Value = "none";
cmd.Parameters.Add(paramEncrypt);
SqlParameter paramEnableCookie = new SqlParameter();
paramEnableCookie.ParameterName = "#cookie";
paramEnableCookie.DbType = DbType.Binary;
paramEnableCookie.Direction = ParameterDirection.Output;
paramEnableCookie.Size = 1000;
cmd.Parameters.Add(paramEnableCookie);
try
{
cmd.ExecuteNonQuery();
SqlParameter outVal = cmd.Parameters["#cookie"];
// Store the enabled cookie so that approle can be disabled with the cookie.
_appRoleEnableCookie = (byte[]) outVal.Value;
}
catch (Exception ex)
{
result = false;
msg = "Could not execute enable approle proc." + Environment.NewLine + ex.Message;
}
But no matter how much I searched I could not find a way to implement on EF.
Another question is: how to Add Application Role to Entity data model designer?
I'm using the below code for execute parameter with EF:
AEntities ar = new AEntities();
DbConnection con = ar.Connection;
con.Open();
msg = "";
bool result = true;
DbCommand cmd = con.CreateCommand();
cmd.CommandType = CommandType.StoredProcedure;
cmd.Connection = con;
var d = new DbParameter[]{
new SqlParameter{ ParameterName="#r", Value ="AppRole",Direction = ParameterDirection.Input}
, new SqlParameter{ ParameterName="#p", Value ="123456",Direction = ParameterDirection.Input}
};
string sql = "EXEC " + procName + " #rolename=#r,#password=#p";
var s = ar.ExecuteStoreCommand(sql, d);
When run ExecuteStoreCommand this line return error:
Application roles can only be activated at the ad hoc level.
I do it the following way (assuming Database First):
I create the DbContext from the db and call it MyEntitiesBase
I inherit from MyEntitiesBase to create MyEntities with the following code:
public partial class MyEntities : MyEntitiesBase
{
private byte[] appRoleCookie;
private void SetAppRole()
{
try
{
appRoleCookie = Database.SqlQuery<byte[]>(
#"
DECLARE #cookie VARBINARY(8000)
DECLARE #r INT
EXEC sp_setapprole 'user', 'pass', #fCreateCookie = true, #cookie = #cookie OUTPUT
SELECT #cookie").First();
}
catch
{
throw new AuthenticationException();
}
}
private void UnSetAppRole()
{
bool failed = Database.SqlQuery<bool>("DECLARE #result BIT; EXEC #result = sp_unsetapprole #cookie = " + appRoleCookie.ToHexadecimalString() + "; SELECT #result").First();
if (failed)
throw new SecurityException();
}
public MyEntities() : base()
{
Database.Connection.Open();
SetAppRole();
}
private bool disposed = false;
protected override void Dispose(bool disposing)
{
if (disposed)
return;
UnSetAppRole();
Database.Connection.Close();
disposed = true;
base.Dispose(disposing);
}
}
Where ToHexadecimalString is an extension method for IEnumerable<byte>, as follows:
public static class BytesExtensions
{
public static string ToHexadecimalString(this IEnumerable<byte> bytes)
{
return "0x" + string.Concat(bytes.Select(b => b.ToString("X2")));
}
}
And that's it. Works with connection pooling on and everything. You just use this inherited version instead of the one generated by EF.
Basically what you are doing is calling a stored procedure.
Entity Framework has functionality to excute stored procedures. Here is an explaination with a video: http://msdn.microsoft.com/en-us/data/gg699321.aspx
If your scrol down to the section "Using Import Functions to Map Stored Procedures" you will find the part that is relevant for you.
