I know this has been asked before and I have tried looking at, at least 30 solutions on stackoverflow if not more, but nothing has worked so far.
I have a tomcat server which is querying into a REST api to fetch and store data. This is to avoid having to query for the data to the remote API every single time my app wants to load the data. The data changes only once in a while and hence this effort.
I have a simple code to connect
final URL url = new URL("https://remote.site.com/api/request?apikey=<some-key>");
HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
connection.setConnectTimeout(5000);
connection.setReadTimeout(5000);
connection.connect();
final InputStream inputStream = connection.getInputStream();
final InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
final Gson gson = new Gson();
MyJSONResponse myJSONResponse = gson.fromJson(inputStreamReader, MyJSONResponse.class);
When I run this code from a Tomcat7 server on my MacBook it runs perfectly fine. I get the JSON and all is hunky dory. So I went ahead and ran this from inside the Tomcat7 server on my Ubuntu and I almost immediately get the SocketException.
I will concede that the data is a bit long, but I would expect it to wait for a few seconds before throwing this exception. But this exception is thrown on the line
HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
which doesn't make sense to me.
To test further, I made a single class program containing just these lines of code and printing out the input stream I get from the remote api and ran this on my Ubuntu box and it runs perfectly fine. So there is nothing wrong with the Ubuntu box and it's internet connectivity. The Tomcat Server seems to be messing up something here.
I have been trying to do multiple things for 4-5 hours now with resetting the connection, not closing it in the finally block and other things but nothing seems to work.
Any help would really be appreciated.
Thanks
Edit:
Adding logs for timeout:

It seems, the site that I was hitting was the culprit. My server seems to work properly when I hit https://www.google.com.
So I believe it has to do with the SSL certificate resolution on my Tomcat.

I guess this is no duplicate, because I checked and applied every answer in exception loading sessions from persistent storage with no luck, for example:
Delete /var/cache/tomcat7/Catalina/localhost/gdi/SESSIONS.ser (which is non-existent anyway if Tomcat is stopped).
I have no broken symlinks:
find / -xtype l 2>/dev/null
returns nothing relevant.
I guess it is a file system rights problem coming from an apt dist-upgrade. Do I really have to reinstall the hole server?
The method GDIApplication.setSessionAttribute (second stacktrace) calls getContextProperty("Session") which leads to an NPE?
The method ApplicationInstance.getContextProperty("Session") belongs to the Echo Framework (https://github.com/echo3/echo3). I'm not exactly sure how it gets hold of the Session object, but the ClassCastException in the first stacktrace might interfere with it.
Try replacing
((HttpSession) getContextProperty("Session")).setAttribute(name, value);
with
Connection conn = WebContainerServlet.getActiveConnection();
conn.getRequest().getSession().setAttribute(name, value);
This gives you access to the current ServletRequest and lets you retrieve the session using Java's ServletRequest.getSession() method, which will create the session if it doesn't yet exist.
As for the ClassCastException during session recreation: I don't know any other way than the ones you have already tried. But if the above tip works, these exceptions may still be annoying, but could turn out to be harmless. I confess, I normally ignore them when they appear...
clean files from \work\Catalina\localhost folder resolved the issue
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'm using Apache Cayenne 4 Milestone 5 and I'm getting this error. The application is not officially deployed but it is being tested within the IntelliJ IDEA.

The applicaion is working normally, but it shows this error after some usage. What is the cause of this error?
I'm using the following method to obtain the runtime each time I need a transaction.
public final static ServerRuntime getAccountsDBPostgreSQLRuntime() {
return ServerRuntime.builder().addConfig("cayenne/cayenne-AccountsDB.project.xml").build();
}
Example:
public final static Long newFanAccount() {
ServerRuntime accountsDBPostgresRuntime = AccountsDBRuntime.getAccountsDBPostgreSQLRuntime();
ObjectContext context = accountsDBPostgresRuntime.newContext();
Fan fan = context.newObject(Fan.class);
context.commitChanges();
Long fanID = (Long) Cayenne.pkForObject(fan);
return fanID;
}
From the stack trace and the code example it looks like you are not reusing the Cayenne stack (ServerRuntime object), creating a new one every time instead. Aside from being slow, this also introduces a resource leak. Each ServerRuntime holds its own connection pool that you do not shut down. So sooner or later PostreSQL server is overflown with open connections.
The solution is to turn ServerRuntime into an app-scoped singleton (e.g. make it a static var of AccountsDBRuntime), and reuse it whenever you need a new ObjectContext.

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 tried to run a stress test using a JMeter test on an API which producing messages toward a RabbitMQ queue. The ressource call a service which open a connection to RabbitMQ, publish a message on a queue via a binded exchange and then close the connection.
When I run a test with a single thread calling the API to produce 45000 messages, It works perfectly.
A problem appears when I try to run a test with five thread producing 9000 messages : a java.net.NoRouteToHostException is thrown (see the trace below).
Running this test I checked connections number on my server and I found more than 30000 TIME_WAIT connections, I decided to reduce the time_wait time out in my sysctl.conf to 20 seconds instead of 120 seconds.
But nothing changed. There are less connections in TIME_WAIT state (around 5000 now) but exception is still thrown.
I tried to increase file descriptors limit in RabbitMQ for the same result.

If I right understand you, i see two ways. First - you must close connection when don't need in it.
connect();
some_action();
disconnect();
Second - connect in setup; send queries, parse responses and others in runTest; disconnect in tearDown.
If you load MQ, i think second way is yours.
