I am trying to configure and use embedded Firebird with log4j. Essentially I want to log my entries to a DB table (Firebird). I am unable to do so with "Connection Refused" error complete call stack pasted below.
There was one possibility for this error that was a mismatched 32 vs 64 bit libraries being used / invoked, but if I write a simple java program and use Jaybird-full-2.2.9.jar I am able to connect and get data. It seems to be a problem when using log4j's property file.
Any help regarding this is appreciated.

You are using an incorrect URL, the URL format for embedded is:
jdbc:firebirdsql:embedded:<database>
The url shown in your config (after removal of the escapes of the colon) is:
jdbc:firebirdsql://embedded:C:\\C\:\\xxxx\\xxxxx.FDB
Removing // should fix this (the same applies to the jdbc:firebirdsql:local URL shown commented out).
URLs with jdbc:firebirdsql://.... are handled by the pure java network protocol implementation. Given the config I would have expected a different error (because parsing the URL would fail), but I assume this might be a result of trying different configurations.

Do you have JAAS configuration file? If you do, then you probably have old format of "initiate" section - com.sun.security.jgss.initiate, note that it's missing ".krb5". It should be com.sun.security.jgss.krb5.initiate.
Or maybe the path to configuration file is incorrect in your server startup command line.
I have IntelliJ and other development tools stopped working today.
IntelliJ says on start:
Cannot start internal HTTP server. Git integration, JavaScript
debugger and LiveEdit may operate with errors. Please check your
firewall settings and restart IntelliJ IDEA
Before this happened I was receiving strange errors on loopback connection on build which is now gone. Currently it says
Error:failed to create a child event loop
Gradle build says:
Protocol family unavaliable
Disabling firewall does not help.
UPDATE
IntelliJ log is full of messages like this:

UPDATE 2
I found the root of the problem: this was caused by proxy autoconfiguration. By some reason address of 127.0.0.1 was processing by proxy and was leading to the web page of proxy server. The addition of
function FindProxyForURL(url,host)
{
if( host == '127.0.0.1' ) {
return "DIRECT";
}
to wpad.dat helped but I still don't understand an entire effect. I have proxy for a long time and it was no causing such an effect previously.
So I think this is also somehow related with IPv6 or something.
I have followed the following tutorial:

I am using Eclipse and have added the latest PostgreSQL JDBC driver to my project (renamed to postgres.jar), my code is as shown in the tutorial.
PostgreSQL Server is running I believe, I am using Windows 10 and have run "pg_ctl start -D ", the path is correct and the server seems to be working as far as I can tell
I have checked in pgAdmin and the database encoding is UTF8.
Can someone help please?
I had the same issue. It was solved by setting a password for the user I was trying to connect with. An older version of the JDBC driver provided a useful error message.
Also had this problem. In my case there was broken connection string, so check if the format of your connection string is correct:
spring.datasource.url=jdbc:postgresql://localhost:5432/my-database
I'm trying to submit a job (a simple word count) to hadoop-2.5.0 (installed on a ubuntu 14.04.1 server running on a virtual machine) from eclipse on windows.

Also, when checking connection configuration on hadoop, it seems it is listening/accepting for connections on 127.0.0.1:8020.
$netstat -lent | grep 8020
tcp 0 0 127.0.0.1:8020 0.0.0.0:* LISTEN 1001 10380
This is the content of core-site.xml, I wonder if it is the source of this problem and how to fix it?
<configuration>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost</value>
</property>
</configuration>
Basically your namenode is listening on the localhost interface, therefore it allows connections only from 127.0.0.1. As you suggested, the error is indeed in the fs.default.name parameter, which should be modified to use the hostname instead of localhost.
Beware that /etc/hosts should contain a line like
192.168.2.216 hostname.fully.qualified.domain.com hostname
You can verify that the hostname is properly setting running the command "hostname" and "hostname -f". "hostname" should return the the name of the system as returned by gethostname, while "hostname -f" should return the fqdn of the system.

You should add mysql drivers jar file to the build path of your project.
