How to disable js and css caching in liferay?

I am developing a theme for liferay,but liferay caching system does not let me to see changes. How can i disable liferay js and css caching?

PS: I am using Liferay version 5.1.1

Solution

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.
