Jetty Server For Mac
- The most recent versions of prior Jetty releases can be found here, with their associated documentation. Note: The canonical repository for Jetty is Maven Central. All releases are always available there first and this download page may lag a bit update wise as post release resources are put into place.
- Originally developed by software engineer Greg Wilkins, Jetty was originally an HTTP server component of Mort Bay Server. It was originally called IssueTracker (its original application) and then MBServler (Mort Bay Servlet server). Neither of these were much liked, so Jetty was finally picked.
- Jun 01, 2018 By default, Spring boot uses embedded tomcat server to run the application. At times, you may need to use jetty server in place of tomcat server. Spring Boot provides Tomcat and Jetty dependencies bundled together as separate starters to help make this process as easy as possible. You can use jetty with following simple steps.

A virtual host is an alternative name, registered in DNS, for an IP address. Virtual hosting takes one of two forms:
- Multiple names can resolve to a single IP address.
- Multi-homed hosts, that is machines with more than one network interface, can have a different name for each IP address.
Jetty users often want to configure their web applications taking into account these different virtual hosts. Frequently, a machine with a single IP address has different DNS resolvable names associated with it, and a webapp deployed on it must be reachable from all of the alternative names. Another possibility is to serve different web applications from different virtual hosts.
You can set virtual hosts in several different ways, including:
- Using a context XML file in the context directory: setVirtualHosts. This is the preferred method.
- Java calls in an embedded usage: Embedding Jetty.
- Within an explicitly deployed webapp (no webapp provider) listed in jetty.xml or similar.
- Using a WEB-INF/jetty-web.xml file (deprecated, but works with the webapp provider if you do not use the context provider).
For descriptions of the various ways to configure Jetty, including links to documents that provide detailed configuration instructions, see How to Configure Jetty.
The examples that follow set virtual hosts in the preferred way, by calling the method ContextHandler.setVirtualHosts.
Configuring Virtual Hosts
When configuring a web application, you can supply a list of IP addresses and names at which the web application is reachable. Suppose you have a machine with these IP addresses and DNS resolvable names:
- 333.444.555.666
- 127.0.0.1
- www.blah.com
- www.blah.net
- www.blah.org
Suppose you have a webapp, xxx.war, that you want all of the above names and addresses to serve. You would configure the webapp as follows:
Assuming you have configured a connector listening on port 8080, webapp xxx.war is available at all of the following addresses:
- http://333.444.555.666:8080/xxx
- http://127.0.0.1:8080/xxx
- http://www.blah.com:8080/xxx
- http://www.blah.net:8080/xxx
- http://www.blah.org:8080/xxx
Configuring Different Webapps for Different Virtual Hosts
You can configure different webapps for different virtual hosts by supplying a different list of virtual hosts for each webapp. For example, suppose your imaginary machine has these DNS names and IP addresses:
- 333.444.555.666
- 127.0.0.1
- www.blah.com
- www.blah.net
- www.blah.org
- 777.888.888.111
- www.other.com
- www.other.net
- www.other.org
Suppose also you have another webapp, zzz.war. We want xxx.war to be deployed as above, and zzz.war to be deployed only from 777.888.888.111, www.other.com, www.other.net and www.other.org:
Webapp xxx.war is still available at:
- http://333.444.555.666:8080/xxx
- http://127.0.0.1:8080/xxx
- http://www.blah.com:8080/xxx
- http://www.blah.net:8080/xxx
- http://www.blah.org:8080/xxx
But now webapp zzz.war is available at:
- http://777.888.888.111:8080/zzz
- http://www.other.com:8080/zzz
- http://www.other.net:8080/zzz
- http://www.other.org:8080/zzz
Configuring Different Webapps for Different Virtual Hosts, But at the Same Context Path
In the example above, webapp zzz.war is available not only at a certain set of virtual hosts, but also at the context path /zzz, whilst the other webapp is available at both a different set of virtual hosts, and at a different context path. What happens if you want them at the same context path, but still at different sets of virtual hosts? You just supply the same context path for each webapp, leaving the disjoint set of virtual host definitions as before:
Now, webapp xxx.war is available at:
- http://333.444.555.666:8080/
- http://127.0.0.1:8080/
- http://www.blah.com:8080/
- http://www.blah.net:8080/
- http://www.blah.org:8080/
and webapp zzz.war is available at:
- http://777.888.888.111:8080/
- http://www.other.com:8080/
- http://www.other.net:8080/
- http://www.other.org:8080/
Configuring Virtual Hosts with Non-ascii Characters
International domain names are names containing non-ascii characters. For example 'http://www.bücher.com'. The DNS internally remains based on ascii, so these kinds of names are translated via an encoding called punycode into an ascii representation. Modern browsers detect these non-ascii characters in URLs and automatically apply the punycode encoding. For example, typing this URL into a browser:
http://www.åäö.com:8080/test/
is translated to the following url:
http://www.xn--4cab6c.com:8080/test/
To use internationalized domain names with Jetty virtual hosts you need to supply the punycode form of the name in your context xml file (and of course you need to supply it to your DNS setup).
For example, if you are running a webapp on port 8080 at context /test, and you want to configure a virtual host for www.åäö.com, you configure its ascii equivalent in the context xml file for the context:
After starting Jetty, you can enter the url http://www.åäö.com:8080/test/ in a browser and reach the webapp.
If you don't have any webapps deployed at /, hitting the URL http://www.åäö.com:8080reaches Jetty's default handler, which serves back a 404 page listing the available contexts:
Notice that the link already has the punycode transformed domain name in it.

Configuring Jetty for highload, albeit for load testing or for production, requires that the operating system, the JVM, jetty, the application, the network and the load generation all be tuned.
Load Generation for Load Testing
- The load generation machines must have their OS, JVM etc tuned just as much as the server machines.
- The load generation should not be over the local network on the server machine, as this has unrealistic performance and latency as well as different packet sizes and transport characteristics.
- The load generator should generate a realistic load:
- A common mistake is that load generators often open relatively few connections that are kept totally busy sending as many requests as possible over each connection. This causes the measured throughput to be limited by request latency (see Lies Damned Lies and Benchmarks for an analysis of such an issue.
- Another common mistake is to use a TCP/IP for a single request and to open many many short lived connections. This will often result in accept queues filling and limitations due to file descriptor and/or port starvation.
- A load generator should well model the traffic profile from the normal clients of the server. For browsers, this if mostly between 2 and 6 connections that are mostly idle and that are used in sporadic bursts with read times in between. The connections are mostly long held HTTP/1.1 connections.
- Load generators should be written in asynchronous programming style, so that limited threads does not limit the maximum number of users that can be simulated. If the generator is not asynchronous, then a thread pool of 2000 may only be able to simulate 500 or less users. The Jetty HttpClient is an ideal basis for building a load generator, as it is asynchronous and can be used to simulate many thousands of connections (see the Cometd Load Tester for a good example of a realistic load generator).
Operating System Tuning
Both the server machine and any load generating machines need to be tuned to support many TCP/IP connections and high throughput.
Linux
Linux does a reasonable job of self configuring TCP/IP, but there are a few limits and defaults that that are best increased. These can mostly be configured in /etc/security/limits.conf or via sysctl
TCP Buffer Sizes
These should be increased to at least 16MB for 10G paths and tune the autotuning (although buffer bloat now needs to be considered).
Queue Sizes
net.core.somaxconn controls the size of the connection listening queue. The default value of 128 and if you are running a high-volume server and connections are getting refused at a TCP level, then you want to increase this. This is a very tweakable setting in such a case. Too high and you'll get resource problems as it tries to notify a server of a large number of connections and many will remain pending, and too low and you'll get refused connections:
The net.core.netdev_max_backlog controls the size of the incoming packet queue for upper-layer (java) processing. The default (2048) may be increased and other related parameters (TODO MORE EXPLANATION) adjusted with:
Ports
If many outgoing connections are made (eg on load generators), then the operating system may run low on ports. Thus it is best to increase the port range used and allow reuse of sockets in TIME_WAIT:
File Descriptors
Busy servers and load generators may run out of file descriptors as the system defaults are normally low. These can be increased for a specific user in /etc/security/limits.conf:
Congestion Control
Linux supports pluggable congestion control algorithms. To get a list of congestion control algorithms that are available in your kernel run:
If cubic and/or htcp are not listed then you will need to research the control algorithms for your kernel. You can try setting the control to cubic with: Vertex standard programming software free download - software.

Low Resource Limits
Must not be configured for less than the number of expected connections.
Thread Pool
It is very important to limit the task queue of Jetty. By default, the queue is unbounded! As a result, if under high load in excess of the processing power of the webapp, jetty will keep a lot of requests on the queue. Even after the load has stopped, Jetty will appear to have stopped responding to new requests as it still has lots of requests on the queue to handle.
Jetty Server Join
For a high reliability system, it should reject the excess requests immediately (fail fast) by using a queuewith a bounded capability. The capability (maximum queue length) should be calculated according to the 'no-response' time tolerable. For example, if the webapp can handle 100 requests per second, and if you can allow it one minute to recover from excessive high load, you can set the queue capability to 60*100=6000. If it is set too low, it will reject requests too soon and can't handle normal load spike.
Below is a sample configuration:
Jetty Server For Mac Mojave
Configure the number of threads according to the webapp. That is, how many threads it needsin order to achieve the best performance. Configure with mind to limiting memory usage maximum available.Typically >50 and <500.
