I have developed a Jooby-Application which is hosted on a netty server. I can access the application on localhost and tests were fine. Now I want to make the app accessable over internet and dont know what is the best way to reach this goal?
The complete application is hosted on a Windows Server, because it uses Excel. (Read/Write over Apache POI. For macros it has to be Windows) Should I try to connect the running netty-server with IIS or can I just forward the requests from outside to localhost? The last mentioned approach propably is a bad idea regarding security issues.
It works with reverse proxy over IIS. I had to install some features like Application Request Routing and URL Rewrite. Then I can start the jooby application (netty server) as usual on a specific port at localhost and set a reverse proxy to it.
I am not sure why being on a window is necessary, anyways, Netty is just a Java network programming framework, it can run on any platform where Java is installed.
You need to host a server, you can buy a VPS, install windows as OS, install Java, you can run your application as you like.
What I understand is you need to test it, for that you can use any port forwarding service like https://pagekite.net/support/intro/features/ to enable "world access" to localhost

I would like to add encrypted connections to my Spring application running on a Tomcat server in a remote host (Amazon EC2 server). I was going to add a Let's Encrypt certificate to my Tomcat, but while searching on the web I read that encrypting my connections could considerably slow down my application. So I was wondering, what would be the best practice to encrypt my application? And does it really slow down so much my application that it would be noticeable? I would really like to implement the best solution, so I am very grateful in advance for suggestions.
The (almost) universal practice is to put a proper high performance web server like nginx or Apache HTTPD in front of your application server acting as a reverse proxy and handling SSL. That way your application server stays on a private network and only a web server is exposed. It’s very easy and you can find many tutorials on how to set it up. Like this one: http://webapp.org.ua/sysadmin/setting-up-nginx-ssl-reverse-proxy-for-tomcat/
We are building php web application while i am a designers and my friend is developer we work on different pcs we want to test the file by runnig on localhost on both of our pc how can we reach it. I have gone through some of concepts in internet but didn't get proper info.
Yes. You need to create a firewall rule to allow access through whatever port you are serving on, probably 8080.
Here is how to create an inbound port rule in windows
Then they should be able to access your server by simply using your ip
i'me working on a web server using play framework 2.0, where the login is executed by a android device software we're also making. And are main concern is that we can't find any support for HTTPS in play 2.0. Sense this is a school project we can't aford clouds nor other proxy to solve the HTTPS for us.
Our main problem is the password and email going in plain sight in the request's body, encrypting and decrypting in the mobile device and on the server looks costly in performance and sense HTTPS takes care of this we wanted to avoid it. Is there any way we can use HTTPS to protect the users login data, or any other suggestion.
If not we might have to migrate all are application to another framework, because it wont look good important confidential data going through the internet without encryption.
Historically, I've seen most folks run the Java/Scala application server behind a reverse proxy of some kind. Setting up HTTPS in apache isn't too hard, and then just use ModProxy to send requests internally to your Play application.
Any one of the reverse proxy systems can likely do this, nginx is popular too, and generally has easier configuration than apache, but I've never used it with HTTPS.
The number one reason normally to do this is security. You can't start a Java program as a non privileged user on port 80. If you start your Java program as root running on port 80, then any hole in your application has root privileges! As a result, starting the Java app on another port, then reverse proxy from an web server that can run as a non-priveleged user on port 80.
(*) This is a slightly over-simplified, but a discussion of this weirdness is beyond the scope of this I think.
It's now possible to use Play and https directly. This was added in Play 2.1
Simply start the server with:
JAVA_OPTS=-Dhttps.port=9001 play start
I have a web server that responds to a number of different sites on port 80. Currently, IIS does the mapping to various sites via host headers, but I'd like to be able to serve other web apps on port 80 hosted in Jetty or Tomcat. IIS prevents that by grabbing all port 80 traffic.
I basically need a reverse proxy to just change the port number to something that another app stack can listen in on. I was looking into nginx but it seems to not be quite ready for prime time on Windows. Eventually I may set up a Linux box specifically for this, but for now I'm interested in a solution which will run all on the same box.
All I really need is something very light which mostly just matches hostname/port and allows rewriting of the port. Does anyone have any suggestions?
If you are running in IIS 7 or above you can use Application Request Routing for that: http://www.iis.net/download/ApplicationRequestRouting
For IIS 5-6, it looks like Apache Tomcat Connector (JK 1.2) is a clean solution. This is an IIS ISAPI filter which allows IIS to act as a reverse proxy for other web servers. It uses Apache JServ Protocol (AJP) to communicate with the app server actually serving requests. Both Tomcat and Jetty implement AJP. URLs are mapped with regex-like config to a particular AJP server instance.
Overview: http://www.iisadmin.co.uk/?p=40&page=3
IIS Config: http://tomcat.apache.org/connectors-doc/reference/iis.html
Mapping Config: http://tomcat.apache.org/connectors-doc/reference/workers.html
This ISAPI plug-in also works with IIS 7.x, but in that case the Application Request Routing (see marked answer) should be considered as it might work better with non-AJP servers.
What is the preferred way of deploying a compojure/sinatra applications? I have multiple sites running on the host so i can't run jetty/mongrel on port 80. How should i handle multiple sites/applications running at the same host?
Use a web server such as Apache that runs on port 80 and use virtual hosts to direct the traffic to the right app server. So basically you would run each application server (jetty/mongrel, etc.) on a different port and then in each virtual host would have a different configuration to use something like mod proxy to forward the traffic to the app server. You could use a different web server such as lighttpd or nginx. For the sinatra app you could also look at Phusion Passenger, a.k.a mod rails, a.k.a mod rack, which theoretically works with any rack app, although I've only used it with Rails.
If you look into it some more you'll find that there are various schemes for forwarding traffic to the app server from a web server, but the basic mechanism for doing this kind of thing always boils down to having a web server that listens on port 80 that uses name-based virtual hosts to then forward the traffic to the appropriate app.
I've been doing this kind of thing with various standalone servers (e.g., AllegroServe) for years. I've found the best approach to be:
Run each server on a different, non-privileged port (such as 8080)
Run pound (or Nginx etc.) on 80, configured to map requests to each application.
Pound is great, and the configurations end up very simple (unlike Nginx). It will also do SSL fronting and HTTP sanitization for you, which takes the burden off your application.
Use passenger! http://modrails.com - it is a plugin for apache and nginx that lets you (very) easily run a ruby app as a virtual host
