I have an application, which needs to connect to MariaDB DB version 10.1 using GSSAPI.
I have enabled the GSSAPI plugin on the database side, and have created a user via -
create user 'user'#'%' IDENTIFIED via 'gssapi' as 'user';
Now, i am trying to connect from the application as -
Class.forName("org.mariadb.jdbc.Driver");
con = DriverManager.getConnection(
"jdbc:mariadb://localhost:3305/schema?user='user'&gssapi-principal-name='user#localhost'");
stmt = con.createStatement();
I am getting the exception when i am trying to get the connection from DB -

I am trying to create customers account in my recurly account.
I got private key as i have created an account in recurly for the development purpose.
with that key and Domain name i am trying to add customers details into my recurly account.
For testing purpose i am just randomly creating an account id and first name in Account object and sending it to recurly account(my account).
But during connecting to Recurly server i am getting below error.
I have verified the connection it seems ok. from web i am able to login and connect to recurly server.
public static void main(String[] args) {
// TODO Auto-generated method stub
// key and domain were correctly written
final String apiKey = "******";
final String Domain = "*****";
Account account = new Account();
account.setAccountCode(UUID.randomUUID().toString());
account.setFirstName("Jeet");
RecurlyClient recurlyClient = new RecurlyClient(apiKey, Domain);
// opening the recurly server.
recurlyClient.open();
// creating account
recurlyClient.createAccount(account);

i was trying out this example authentication code from ORacle. The only thing I change is the logincontext
try {
lc = new LoginContext("SampleConfig", new TextCallbackHandler());
}
my jaas.conf file looks like this
SampleConfig {
com.sun.security.auth.module.Krb5LoginModule required client=true useTicketCache=false;
};
I put the conf file together with the class. However when i run it, it gives me this error

dorothy is a normal test user that I created using "Active Directory Users and Computers". Does this account need to be "Administrator" because the prompt says [Administrator]? I have also ticked the "Use Kerberos DES Encryption types" and also the AES 128, 256 support in the user profile.
This is my AD (win 2008 server) setup
C:\> ksetup
default realm = corp.example.com (NT Domain)
No user mappings defined.
How to solve this? I am guessing this is a AD config problem and not with JAas? thanks
I am not able to connect with SQL server 2008 R2 using java. The same code is working with SQL server 2005.
I have tried to find out the port and ip for the sqlserver service and it is giving me
ip - 0.0.0.0 and port 1434
I tried to use the same connection string that works in SQL Server 2005, but it won't work for me in SQL Server 2008. Here is my connection string:
conn=DriverManager.getConnection(jdbc:sqlserver://127.0.0.1:1434:DatabaseNameconnect?autoReconnect=true,user, password);
This is the Error:
jdbc:sqlserver://127.0.0.1:1434;DatabaseName=connect;user=falcon;Password=admin
Could not connect to database

Any help ?
There are many possibilities for your problem:
Firewall
No TCP/IP connector
some services are not running
Try to connect with the SQL-management Studio to you database. If this works, try to connect with SQL-Authentification over TCP/IP.
update
Take a look at the Documentation at http://msdn.microsoft.com/en-en/library/ms143693(v=sql.90).aspx
One obvious problem is that SQL Server listens on port 1433, not 1434. I've already answered this question elsewhere, but I can't be sure if it's an exact match for your problem because you haven't told us what error message you get.
I have created an application using hibernate... It works fine with database when I run it through Netbeans. But when I build application (using Clean and Build tool) it does not work with database.

Please Help Me.
Please Help Me.
This has no relationship to the jar - rather, it's a database connection privileges issue.
1) the address or account information in your hibernate configuration, which is packaged with the jar- is incorrect or incomplete compared to that used by your working netbeans code.... Are you using the same configration file in your jar as netbeans?
Or
2). You are running the jar from a machine which is not authorized to connect to the database - for example, maybe you are connecting as root from a non root authorized ip address.... Are you running the jar on the same machine which you use netbeans on?
I'm running into an issue with my applet. It's supposed to take a url and parse the html there to construct an image. I've gotten it to work on my eclipse debugger. However, when I try to use it on a web browser I get an AccessControlException. I'm using the jEditorPane.setPage(url) method. Currently both the applet and url are hosted on my localhost and I did self sign the applet.

An unsigned applet is only allowed to connect to the host it came from. And even for signed applets, in methods invoked from code less trusted (like the javascript code here), it has only the rights of this code (or more exactly, the intersection of all rights).
To be able to do everything for which your applet has the rights, wrap your rights-needing code with AccessController.doPrivileged(...). (But make sure that this can not do dangerous things when given malicious arguments from outside.)
