At work, I am trying to deploy a java 8-based application on Tomcat 7 server.
The application should call some RESTful api based on another server (which is still ours). By reading some resources online I decided to use a HTTP request client library called Unirest.
I tried to call the api using Postman and everything works fine.
I deployed my application on my LOCAL Tomcat 7 server and it runs smoothly without problems and Unirest does its job correctly.
When I deploy the application on the Tomcat 7 server, every Unirest call, leads to a connect timeout.
This is the stacktrace:
com.mashape.unirest.http.exceptions.UnirestException: org.apache.http.conn.ConnectTimeoutException: Connect to srv-erp2web.rold.corp:80 [srv-erp2web.rold.corp/192.168.5.100] failed: connect timed out

I haven't find any clue on the internet about how this can happen. The really strange thing is that Unirest calls correctly the api on my local Tomcat.
Here a snapshot of the code that I use to call the api:
public static String getAccessToken() {
logger.log(Level.FINE, "calling smartfabauth to get authentication token");
String accessToken = "";
try {
Unirest.setTimeouts(0, 0); // NO TIMEOUT
HttpResponse<JsonNode> response = Unirest.post(POST_TOKEN_ENDPOINT)
.header("content-type", "application/x-www-form-urlencoded")
.header("cache-control", "no-cache")
.body("grant_type=" + GRANT_TYPE + "&client_id=" + CLIENT_ID + "&client_secret=" + CLIENT_SECRET + "&scope=" + SCOPE)
.asJson();
accessToken = response.getBody().getObject().getString("access_token");
} catch (UnirestException | JSONException e) {
logger.log(Level.SEVERE, "[Exception] getAccessToken", e);
}
logger.log(Level.FINE, "authentication token obtained");
return accessToken;
}
Note that POST_TOKEN_ENDPOINT, GRANT_TYPE, CLIENT_ID, CLIENT_SECRET and SCOPE are some constants declared in class necessary to correctly call the api.
Any help would be apreciated.
Thanks in advance.
I suspect this is a firewall/proxy issue.
You can check the connectivity by pinging srv-erp2web.rold.corp from the machine where you want to run Tomcat 7.
If you see packet loss, try below tracert(windows) or traceroute(*nix) machines.
Usual syntax is tracert srv-erp2web.rold.corp
Above tracert shows the request path from source to destination. And also tells where the request is failing.
If the packet loss is because of proxy server, provide proxy host, port and credentials if any.
If the packet loss is because of firewall, enable the port.
Hope this helps!

i tried connecting to the database via terminal and its working just fine, am using sequel Pro as a GUI tool for managing my database, it also connects just fine. so i cant stop wondering what the problem might be.
i tried checking th firewalls, everything is okey.
also below is the url i use to connect to the database
DB_URL="jdbc:mysql://localhost/pickdatabase";
NOTE: i know the url is missing the port number but its been working just fine for the past week without using the port number. So i tried including the port number as well(3306) but it still doesnt work, i even tried using "127.0.0.1" instead of "localhost" in the URL but it still doesnt work.
To me this sounds like it's a permissions or firewall issue. What is the computer that the database is housed on? I would also double check whether or not the IP that you are connecting from has a mysql user that has permissions to connect. You will likely have to add a root user with all permissions this command is start
CREATE USER 'newuser'#'localhost' IDENTIFIED BY 'password';
I need to send email through my web-application to some gmail account. I have written and tested code in windows machine and it works well. it sends emails from windows (Apache tomcat). But not able to send emails when hosted on Ubuntu in same Apache tomcat version.
what i have tried so far is :
tried both the ports 465 and 587
tried to add ports using command sudo ufw allow 465
but i still get same error.
Here is the error stack trace

In my case problem was with proxy. for help in checking the connectivity problem please go through the links in comments.
so here's the problem I'm having:
When I'm trying to connect to an smtp sever, and when I try it in netbeans, it gives me an error saying I can't connect:
I know that my computer can connect to the mail server, since telnet works perfectly fine when I try it, which makes me think the issue is with the code.
However when the program I wrote is used on a different computer, it works just fine. According to wireshark, the program never tried to connect to the mail server.
I've tried making myself an administrator on the firewall, and that has no affect on the program.
here's the code I'm using:
private static final Properties SYS_PROPS = System.getProperties();
public void sendEmail(String user, String Message, String subject, String recipient) throws ResourceException {
try {
//Set the host property
SYS_PROPS.setProperty("mail.smtp.host", "host");
System.setProperty("java.net.preferIPv4Stack" , "true");
//Create a session for all the emails
Session session = Session.getDefaultInstance(SYS_PROPS);
//Get the name of the contact peep
String name = user;
//Create a new message
MimeMessage message = new MimeMessage(session);
MimeMultipart multiPart = new MimeMultipart();
//Set to, from, and subject
message.setFrom(new InternetAddress("http://localhost:8084/appName"));
message.addRecipient(RecipientType.TO, new InternetAddress(recipient));
message.setSubject(subject);
//Next, add the message part
BodyPart arm = new MimeBodyPart();
arm.setContent(Message, "text/html");
multiPart.addBodyPart(arm);
//Set the multipart to the message
message.setContent(multiPart);
//Send the message
Transport.send(message);
} catch (MessagingException ex) {
log(ex);
}
}
My current theory is that I somehow have to configure netbeans, or tomcat, to allow me to send mail.
I would really appreciate any help that you can give!
I'm getting this error when I use the program:

I have problem. My code work good on my localhost machine. But when I deploy .war on server It can't send email. I don't know why.
Server is in the same network and ping with succes. mserv3.int.pan.wroc.pl So it's not problem with DNS.
My local dev machine: Ubuntu 14.04 + Tomcat 7
Server: CentOS 6 + Tomcat 7
My server hostname
bash> hostname
vm10.int.pan.wroc.pl
I add:
props.put("mail.smtp.localhost", "vm10.int.pan.wroc.pl");
and now it work, but I don't understand why. I have to share my .war. People should not have to edit this on every machine with CentOS 6.
The stacktrace tells you the cause of the problem:
Caused by: javax.mail.MessagingException: Can't get local hostname. Please correctly configure JDK/DNS or set mail.smtp.localhost
It seems, as if JavaMail is not able to determine the name of the host it is running on. Try the advices in the exception.
What is the result of the following statment?
bash> cat /etc/hostname
If it is impossible to set a hostname or get a name via DNS, then try to use the property mail.smtp.localhost.
Here is the source code of the failing method. Perhaps the JavaDoc of the called #getHostName()-method is helpful:
Gets the fully qualified domain name for this IP address. Best effort method, meaning we may not be able to return the FQDN depending on the underlying system configuration.
If there is a security manager, this method first calls its checkConnect method with the hostname and -1 as its arguments to see if the calling code is allowed to know the hostname for this IP address, i.e., to connect to the host. If the operation is not allowed, it will return the textual representation of the IP address.
It seems I'm having the same problem as described in this post, except I'm using the SolrJ client. Since that question remains unanswered, I'm posting my own here.
I get intermittent SolrServerExceptions (Connection refused caused by a Connection timed out) on an otherwise well-running setup. The SolrJ client and Solr server are both running on AWS EC2 instances (Bitnami Ubuntu AMIs) that are talking to each other just fine. It's just that every once in a while (several times a day) I see these errors in the tomcat logs (on the client side only! There is no evidence on the server log that anything went wrong). I can't tell for sure, but the timeouts seem to be getting logged about 30s after the query is issued.
This is a new system with two cores, each with < 1000 indexed documents running as a single instance (no zookeeper). Traffic volume is very low at this point.
Here is the complete stacktrace:

UPDATE: SolrJ is version 4.6.0, the Solr server is 4.7.1. I think we've narrowed it down to a problem with SolrJ client connections and/or network issues. I came to this conclusion by looking at the logs for Apache that sits in front of Solr, and there are no errors or entries in the access logs for the failed connections. If Apache isn't even getting the requests, then the Solr server can be eliminated as the problem.
Does SolrJ use any type of HTTP connection pooling? Perhaps I'm hitting a stale or orphaned connection.
