I´m trying to create a terminal to connect with EPI in CICS Transaction Gateway. My code is below. When the connect() method exectues, an exception is generated.

The CICS TG server is running on an AIX node, I tried generating the basic terminal and the extended terminal but anyone can connect.

Here is the code to connect to hive in kerberos mode
import java.sql.*;
import org.apache.hadoop.security.UserGroupInformation;
public class hive2 {
public static void main (String args[]) {
try {
org.apache.hadoop.conf.Configuration conf = new org.apache.hadoop.conf.Configuration();
conf.set("hadoop.security.authentication", "Kerberos");
UserGroupInformation.setConfiguration(conf);
UserGroupInformation.loginUserFromKeytab("hive/ambari2012.howard2012.local#HOWARD2012.LOCAL", "/etc/security/keytabs/hive.service.keytab");
Class.forName("org.apache.hive.jdbc.HiveDriver");
System.out.println("getting connection");
Connection con = DriverManager.getConnection("jdbc:hive2://ambari2012:10000/;principal=hive/ambari2012.howard2012.local#HOWARD2012.LOCAL");
System.out.println("got connection");
con.close();
}
catch (Exception e) {
e.printStackTrace();
}
}
}
the issue is doesnt matter what keytab I pass it's always giving the below error -
ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console.
java.io.IOException: Login failure for hive/ambari2012.howard2012.local#HOWARD2012.LOCAL from keytab /etc/security/keytabs/hive.service.keytab

at hive.connect.java.hive.connect.java.App.main(App.java:21)
Caused by: javax.security.auth.login.LoginException: Unable to obtain password from user
I don't think it's even trying to check if the right keytab is given to it.
How should I ensure it's reading the correct keytab file and also if the keytab file is not present it should give unable to locate the keytab
Please let me know if I have to copy the keytab ,krb files in my local machine
I don't think you can connect to a kerberized HIVE this way.
Try using a JAAS file https://docs.oracle.com/javase/7/docs/technotes/guides/security/jgss/tutorials/LoginConfigFile.html
and add the 2 following properties to your JVM :
-Djavax.security.auth.useSubjectCredsOnly=False
-Djava.security.auth.login.config=jaas.conf
Sample file jaas.conf :
com.sun.security.jgss.krb5.initiate
{ com.sun.security.auth.module.Krb5LoginModule required
useKeyTab =true
useTicketCache =false
doNotPrompt =true
principal ="hive/ambari2012.howard2012.local#HOWARD2012.LOCAL"
keyTab ="/etc/security/keytabs/hive.service.keytab"
debug =false;
};
Client
{ com.sun.security.auth.module.Krb5LoginModule required
useKeyTab =true
useTicketCache =false
doNotPrompt =true
principal ="hive/ambari2012.howard2012.local#HOWARD2012.LOCAL"
keyTab ="/etc/security/keytabs/hive.service.keytab"
debug =false;
};
I was missing jar files so if you add all jar files it's fine, here is the complete code

i have tried to create one small java code to handle couchbase lite database and to do push pull operation
senario in depth is as follows
what i did is i have created bucket named as sync_gateway,
and conected with couchbase server by below config.json
{
"interface":":4984",
"adminInterface":":4985",
"databases":{
"db":{
"server":"http://localhost:8091",
"bucket":"sync_gateway",
"sync":function(doc) {
channel(doc.channels);
}
}
}
}
this had created metadata in sync_gateway bucket on server,
the n i have written sample java code for local database CBL , and wrote functions for push pull operations ...
code:

now i am stating sync gateway by that config file and running java code to create document on CBL and CB server by push pull operation.
bt it is showing error as
Jul 08, 2016 10:27:21 AM com.couchbase.lite.util.SystemLogger e
SEVERE: RemoteRequest: RemoteRequest{GET, https://localhost:4984/db/_local/2eafda901c4de2fe022af262d5cc7d1c0cb5c2d2}: executeRequest() Exception: javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated. url: https://localhost:4984/db/_local/2eafda901c4de2fe022af262d5cc7d1c0cb5c2d2
so is there any misunderstanding in my concept??? and how do i resolve this problem??
You have not set up your Sync Gateway for SSL. You need to add the SSLCert and SSLPass keys to your config file.

It is never suggested to mix production and non-production traffic on the same EMS messaging instance. That is a very risky practice since it introduces the possibility of inadvertently sending non-production traffic to production applications. I would suggest first checking with your EMS operations team as they can likely point you to a development EMS instance that you can use.
For unit and/or integration testing where you are not looking to stress-test the environment, many developers install an instance of EMS on their local development workstation. Again your EMS operations team may be able to provide you with a license and installation binary to install locally.

I'm trying to develop an adf mobile app using jDeveloper and oracle sql developer.
I have connected jDev and sql. I want to populate selectOneChoice comp. that I m gonna fetch datas.
this is my connection method;
package salesorder.application;
import groovy.sql.Sql;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.SQLException;
import javax.sql.DataSource;

ds.setURL(jdbcUrl);
conn=ds.getConnection(userid,password);
} catch (SQLException e) {
// if the error message is "out of memory",
// it probably means no database file is found
System.err.println(e.getMessage());
}
}
return conn;
}
}
and this, my method to fetch data;
private void Execute() {
Trace.log(Utility.ApplicationLogger, Level.INFO, Customers.class, "Execute",
"!!!!!!!!!!!!!!!!!In COUNTRY Execute!!!!!!!!!!!!!!!!!!!!!!!!!");
try{
Connection conn = DBConnection.getConnection();
customers.clear();
conn.setAutoCommit(false);
PreparedStatement stat= conn.prepareStatement("select cust_account_id,account_name from hz_cust_accounts_all where account_name is not null order by account_name asc");
// fetching customers name
ResultSet rs = stat.executeQuery();

while(rs.next()){
int id = rs.getInt("CUST_ACCOUNT_ID"); // customer id
String name = rs.getString("ACCOUNT_NAME"); // customer name
Customer c = new Customer(id,name);
customers.add(c);
}
rs.close();
} catch (SQLException e) {
System.err.println(e.getMessage());
} catch (Exception e) {
System.err.println(e.getMessage());
}
}
when i try to start application, an error comes up like that.
i cant use an image. so
Error
oracle.jdbc.pool.OracleDataSource
I dont know how Im gonna solve that, i cannot figure out why . Any help ?
Just to clarify - are you trying to use ADF Mobile (AMX pages)?
If so then you can't connect with JDBC to a remote database from the client.
You can only connect with JDBC to the local SQLite DB on your device.
To access data from remote servers you'll need to expose this data with web services and call those.
