Cannot connect java mail to postfix smtp server - java

I'm facing an issue right now. I configure my postfix server together with dovecot and everything works well so far. I could connect some accounts using my phone email client with the parameters:
Host: imap.mydomain.com
email: xxx#mydomain.com
password: xxxxxxxx
port: 993
and
Host: smtp.mydomain.com
email: xxx#mydomain.com
password: xxxxxxxx
port: 465
Accept all SSL certificates
Now I want to connect my java app with the smtp parameters to send emails. Unfortunately, it takes too long and then I get a time out exception.
On the server, I get the following from the logs:
Sep 01 12:55:05 mail.mydomain.com postfix/smtps/smtpd[125179]: lost connection after AUTH from unknown[212.70.149.71]

Here is my config in java:

Here the java stacktrace I get:

org.postgresql.util.PSQLException: FATAL: no pg_hba.conf entry for host Linux error that works on Windows

I have looked at many (too many) similar questions here and tried over and over to solve this one but I can't quite get it to resolve.
I have a java code that connects to a PostGreSQL server on a RHEL 8.2 box to query and return a value. When I run it on my Windows 10 laptop; it works with no issues. However, when I run it locally on the Linux box it fails with the dreaded org.postgresql.util.PSQLException: FATAL: no pg_hba.conf entry for host.
The java code is made by a ETL software called Talend; and the code is run on Linux by RunDeck.
To make matters more confusing, I can login on Linux as the postgres user and use the psql interface to connect to the db with the same host, port, db, and user I'm using in Java without error-
psql -h [server ip] -p 5432 -d my_special_db -U my_db_user
I have checked the server settings, the pg_hba.conf file, the user permissions, the log files and tried changing all of the above to get some sort of return; all to no avail.
I have added to pg_hba.conf:
host my_special_db my_db_user [server ip]/32 md5
host my_special_db my_db_user [server ip with .0 as the last quatraine]/24 md5
host my_special_db root ::1/128 trust
host all all [server ip]/32 trust
I have tried multiple connection modifiers like:
sslfactory=org.postgresql.ssl.NonValidatingFactory&sslmode=prefer
or
sslmode=prefer
or
sslmode=Require
or
no modifier at all
Please advise.

Update 4:
After doing some more searching, I have found that the default for the postgres logging isn't verbose; so this is the verbose part:

I have gotten this error even after the following updates-
update to the postgresql.conf file:
edit 1
ssl = off
edit 2
ssl = on
edit 3
#ssl = off
updated the log level in the postgresql.conf file to
log_line_prefix = '[%p] [%c] [%m] [%v] [%e] [%i] [%d] [%u] [%a] [%r] [%l] [%x]: '
...
log_statement = 'all'
updated the pg_hba.conf file to start with:
# Allow any user on the local system to connect to any database with
# any database user name using Unix-domain sockets (the default for local
# connections).
#
# TYPE DATABASE USER ADDRESS METHOD
local all all trust
# The same using local loopback TCP/IP connections.
#
# TYPE DATABASE USER ADDRESS METHOD
host all all 127.0.0.1/32 trust
# The same as the previous line, but using a separate netmask column
#
# TYPE DATABASE USER IP-ADDRESS IP-MASK METHOD
host all all 127.0.0.1 255.255.255.255 trust
# The same over IPv6.
#
# TYPE DATABASE USER ADDRESS METHOD
host all all ::1/128 trust
# The same using a host name (would typically cover both IPv4 and IPv6).
#
# TYPE DATABASE USER ADDRESS METHOD
host all all localhost trust
hostssl all all 0.0.0.0/0 md5
also updated the connection params with-
sslfactory=org.postgresql.ssl.NonValidatingFactory
According to postgres this is supposed to stop any and all SSL issues and just let the connections through-
https://jdbc.postgresql.org/documentation/head/ssl-client.html
"A non-validating connection is established via a custom SSLSocketFactory class that is provided with the driver. Setting the connection URL parameter sslfactory=org.postgresql.ssl.NonValidatingFactory will turn off all SSL validation."

I couldn't paste the error log here because after making it verbose it was very long- so I made a gist
Last update:
I removed the Gist because the peeps here helped me find my error:
okay, so the issue was 3 things; thing 1, we have a 'properties' file that I thought was set to this server this db; and it wasn't // thing 2, the default logging was set to 'warning' and didn't have enough information so after putting it to debug level 5 (the most data) and on 'all' events; I finally saw a error message that made me realize it was pointed at the wrong db // thing 3, in the many (too many) iterations of my pg_hba.conf file I had added then removed the IP address.
so now it's working, lol

Why OpenCV-Java can not connect to mjpeg-stream (from flask) while Python3/cv2 can do it?

A Python/flask server (server.py) acts as WebCam proxy.
Python3+cv2 (opencv4.1.1) using cv2.VideoCapture() can connect and display the stream (client.py).
Java+OpenCV (1.8.0_192 / opencv-4.1.1_vc14_vc15) seems to have connect issues (client.java).
Note: While cv2.open(url) sends just one GET request. Using Java/OpenCV the server sees 2 GET requests and the capture stays close.
Below the source code and the command-line calls ... running on Win7Pro.
Is there any idea why it is not working in Java?

That means that java executable could not be found.
The fact is that I have another Symfony2 app on the same server and it works there. I compared both config.yml files and they are identical. What is missing in this other app?
This is the full config.xml file:

That is strange.... java does not exist in that folder... however, I have another symfony2 site in the same server and it works. I really don't know what assetic is doing to publish assets.

how to configure a email functionality in play-java 2.5.4

I wrote the following code for email functionality:
import org.apache.commons.mail.DefaultAuthenticator;
import org.apache.commons.mail.EmailException;
import org.apache.commons.mail.HtmlEmail;
import play.mvc.Controller;
import play.mvc.Result;
public class MailController extends Controller {
public Result sendEmail() throws EmailException {
HtmlEmail email = new HtmlEmail();
String authuser = ".......#gmail.com";
String authpwd = "XXXXXXX";
email.setSmtpPort(587);
email.setAuthenticator(new DefaultAuthenticator(authuser, authpwd));
email.setDebug(true);
email.setHostName("smtp.gmail.com");
email.setFrom(".........#gmail.com", "SenderName");
email.setSubject("TestMail");
email.setHtmlMsg("<html><body><h1>welcome to u</h1></body></html>");
//email.addTo(".......#gmail.com", "receiver name");
email.setTLS(true);
email.send();
return play.mvc.Results.ok("Success");
}
}
However, I'm facing problems (such as exceptions getting caught in Netty).
I added a plugin in bulid.sbt:
libraryDependencies ++= Seq(
"com.typesafe.play" %% "play-mailer" % "5.0.0-M1"
)
application.conf:
# Mailer
# ~~~~~
play.mailer {
host=smtpout.secureserver.net
port=587
ssl=false
tls=false
user=my username
password=my password
debug=false
mock=false
}
This is one of the errors that I'm facing:
[error] p.c.s.n.PlayRequestHandler - Exception caught in Netty

How can I fix this?
my application.config file is as below
# This is the main configuration file for the application.
# https://www.playframework.com/documentation/latest/ConfigFile
# ~~~~~
# Play uses HOCON as its configuration file format. HOCON has a number
# of advantages over other config formats, but there are two things that
# can be used when modifying settings.
#
# You can include other configuration files in this main application.conf file:
#include "extra-config.conf"
#
# You can declare variables and substitute for them:
#mykey = ${some.value}
#
# And if an environment variable exists when there is no other subsitution, then
# HOCON will fall back to substituting environment variable:
#mykey = ${JAVA_HOME}
## Akka
# https://www.playframework.com/documentation/latest/ScalaAkka#Configuration
# https://www.playframework.com/documentation/latest/JavaAkka#Configuration
# ~~~~~
# Play uses Akka internally and exposes Akka Streams and actors in Websockets and
# other streaming HTTP responses.
akka {
# "akka.log-config-on-start" is extraordinarly useful because it log the complete
# configuration at INFO level, including defaults and overrides, so it s worth
# putting at the very top.
#
# Put the following in your conf/logback.xml file:
#
# <logger name="akka.actor" level="INFO" />
#
# And then uncomment this line to debug the configuration.
#
#log-config-on-start = true
}
## Secret key
# http://www.playframework.com/documentation/latest/ApplicationSecret

#
# You can also extend Play functionality by using one of the publically available
# Play modules: https://playframework.com/documentation/latest/ModuleDirectory
play.modules {
# By default, Play will load any class called Module that is defined
# in the root package (the "app" directory), or you can define them

# Play supports multiple methods for verifying that a request is not a CSRF request.
# The primary mechanism is a CSRF token. This token gets placed either in the query string
# or body of every form submitted, and also gets placed in the users session.

How to configure pgpool for reasonable speed

I have a problem with pgpool II configured in master-slave mode with replication on slony.
I have configured postgres databases on each server to run as fast as they can and this was verified by me when I set up connection directly to the db server. However when connection is established by pgpool sth goes wrong, my webapp on tomcat starts very slowly(30min in compare to 5min without pgpool).
I can't figure out what is wrong. On working webapp communication is a bit slower, but difference is so much smaller than at startup.
PGPool use ssh tunnels to communicate with servers.
I've read sth about pgpool and if I understood correctly number of connections(pools) is determine by tuples(database, user). I use only one database and user, is that a reason? If so is there anything I can do to speed up pgpool?
Configuration info:
CentOS 6 x64
Postgres 9.2.4
PGPool II 3.2.5
There are 3 servers, two with postgres database which is replicated by slony and on another one pgpool is running.
