Change Jetty default port

Question

Jetty default port is 8080, but I want to change to default port to some other port (9999).

I read a few tutorials and they said almost all of configuration information is by default maintained in file jetty.xml, this file is located under $JETTY_HOME/etc/. Then, change property jetty.port to 9999. However, when I opened up that file, I couldn't find jetty.port property inside the jetty.xml. I'm currently using Jetty-9.2.1 and the port is at 8080.

I found jetty.port property under jetty-http.xml file. Even though I changed the port to 8090 in the jetty-http.xml file, jetty is still running at port 8080.

I was also advised to use an integration test to configure Jetty to use other port. There's a integration-tests.properties file inside the project. Maybe a solution is to set jetty.port to 9999 inside this file?

integration-tests.properties:

host = localhost
port = 9999

Solution 1

does it work if you set the port when you start it from the command line like this:

java -jar start.jar -Djetty.port=9999

Solution 2

I did this in Jetty 9.x version. You need to go to $JETTY_HOME/start.ini file and edit this setting jetty.port.

Lets say that you want to run jetty at 9090 port: Please change jetty.port setting in $JETTY_HOME/start.ini from

jetty.port=8080

to

 jetty.port=9090

Then start jetty using java -jar start.jar option. Then jetty will be running at 9090 port than default 8080 port. Then do curl -i -XGET "http://localhost:9090". That should give you 200 http status.

Thats it.

Solution 3

Update:

On Jetty 9.x, jetty.port has been deprecated and you can use jetty.http.port instead, as shown below:

$> cd $JETTY_HOME && java -jar start.jar -Djetty.http.port=8080

Solution 4

On jetty 9.2.3.v20140905 it`s need to write in /etc/default/jetty

# JETTY_ARGS
#   The default arguments to pass to jetty.
#   For example
JETTY_ARGS="jetty.port=8080 jetty.spdy.port=8443 jetty.secure.port=443"

but this change only http port. To change https port in jetty 9.2 create ini file $JETTY_HOME/start.d/https.ini

# Initialize module https
#
--module=https
## HTTPS Configuration
# HTTP port to listen on
https.port=8443
# HTTPS idle timeout in milliseconds
https.timeout=30000
# HTTPS Socket.soLingerTime in seconds. (-1 to disable)
# https.soLingerTime=-1

jetty 9.3 in /etc/default/jetty

# JETTY_ARGS
# The default arguments to pass to jetty.
# For example
JETTY_ARGS="jetty.http.port=8080 jetty.ssl.port=443"

or command line parameters -Djetty.http.port=8080 -Djetty.ssl.port=443

Solution 5

I changed the port successfully, you can try to edit jetty.port in the file located at $Jetty_home/start.d/http.ini.

Changing the jetty.port setting inside jetty-http.xml worked for me. Maybe you have another application using port 9999?

[MHSFisher]

For changing ssl default port: stackoverflow.com/a/72082416

[wag0325]

This doesn't change the default port. After running this line, Jetty still runs under port 8080 when I run java -jar start.jar. I'm looking for a way to permanently change the default port.

[Magnus Lassi]

@wag0325 I was just wondering if it would make a difference in order to troubleshoot the issue. After I updated jetty/start.d/http.ini and changed the port to 9999 and then run the default settings: java -jar start.jar it starts up on port 9999. If you need to run it from maven then this post may help: link

[Himalay Majumdar]

The documentation said.. mvn -Djetty.http.port=8181 jetty:run but your suggestion works for me. May be because I have context path defined like this ` <plugin> <groupId>org.mortbay.jetty</groupId> <artifactId>jetty-maven-plugin</artifactId> <version>8.1.14.v20131031</version> <configuration> <webAppConfig> <contextPath>/http</contextPath> </webAppConfig> </configuration> </plugin> `

[Mihai Alexandru-Ionut]

That's a great answer.

[Anunay]

mvn -Djetty.port=8181 jetty:run helps you start jetty on port 8181

[JSelser]

BTW if using spring boot with jetty underneath you should use --server.port=8090
