Under Tomcat (bundled)

Edit the setenv.sh file (setenv.bat on windows) Search for the line that sets the JAVA_OPTS variable Add -Dexternal-properties=portal-developer.properties to the list of options For example: 

JAVA_OPTS="-Xms256m -Xmx1024m  -XX:PermSize=32m -XX:MaxPermSize=160m -Dfile.encoding=UTF8 -Duser.timezone=GMT+2 
-Djava.security.auth.login.config=$CATALINA_HOME/conf/jaas.config 
-Dorg.apache.catalina.loader.WebappClassLoader.ENABLE_CLEAR_REFERENCES=false 
-Dexternal-properties=portal-developer.properties"

Note that this has to be all on one line.

If you were already using the external-properties system property to load some other properties file, add portal-developer.properties with commas.

This is however for the later version 5.2.3+ Not sure why you are still @ 5.1.1, I would update to take advantage of some updated structure and dev handling. In the past there was more work required to get the caching disabled.

    Just to add more information to the @Jakub's reply. The file `portal-developer.properties` is already bundled in Liferay so don't worry to create one and/or to ask about what it should contains. In a standard Liferay installation (bundled with Tomcat) it should be located in: `./webapps/ROOT/WEB-INF/classes/portal-developer.properties`. – Rubens Mariuzzo Apr 05 '11 at 15:16
  • @Rubens Mariuzzo, welcome, I know what a pain Liferay can be to work with ;) – Jakub Apr 05 '11 at 18:25

    Indeed, Liferay is pretty useful, but can make you spend hours in simple and common tasks for developers. – Rubens Mariuzzo Apr 05 '11 at 20:29

    I'd like to suggest to change JAVA_OPTS to CATALINA_OPTS. Reference, justification and outcome: https://issues.liferay.com/browse/LPS-26464 – Olaf Kock Jan 20 '13 at 20:44
  • After making this change, is the restart of tomcat necessary? – Ralph David Abernathy Feb 19 '16 at 18:26

it's all about Liferay servlet filters. You need to turn some of them off. The best place for that is portal-developer-ext.properties.

You make liferay read it by 2 possible ways :

JVM parameter  -Dexternal-properties=portal-developer-ext.properties

or add this property to portal-ext.properties

include-and-override=portal-developer-ext.properties

  • Thanks for the bit about 'include-and-override'. I put that in my portal-ext.properties file on my Liferay 6.1.0 server and it worked! – CatsAndCode Jan 11 '12 at 17:49

To disable caching of JS and CSS resources in Liferay Portal 6.1+*, add the following line to your portal-ext.propeties file:

browser.cache.disabled=true

*This may work in older versions as well, but I haven't tested it.

    As links tend to go off-line earlier or later, you could try to provide a summary of the things shown on that site. – Nippey Oct 15 '12 at 06:02
  • Read the page, it's actually not about caching but about running a one-time-import. (Only in the title there is something written with caching of *.proerties files) – Manuel Manhart Jul 17 '20 at 11:34
