Eclipse - Dynamic Web Project not picking up chang

问题:

I am using Run As -> Run on server, to run my web project on the local tomcat instance.

Problem is, when I make changes on JSP's and other project component, sometimes Eclipse picks this changes up, sometimes is does not. It seems kind of random...

This could be due to various reasons, and cannot give a solid answer to it without knowing the exact cause. But, there are few things that could lead to this.

• Check your Build Automatically setting (Project -> Build Automatically). This has to be enabled to publish your changes.
• Under Server definition, check the Publishing settings. If it is none, then nothing will be published. If you have set a publishing interval, then you have to wait till that time is elapsed to get your copy synchronized with server.
• If it is only related to JSP / JS, your browser cache could be giving you an old copy. Try clearing out your cache.

I was also getting the same issue. I tried clearing cache which worked sometimes but this was painstaking because, for the JS or CSS changes, this was taking more time.

I found an alternative solution (which worked best as I didn't have to clear the cache again and again)

Add the below properties in the portal-ext.properties for JS and CSS refresh issue:

layout.template.cache.enabled=false
theme.css.fast.load=false
javascript.fast.load=false
minifier.enabled=false
com.liferay.portal.servlet.filters.minifier.MinifierFilter=false
include-and-override=portal-developer.properties

This should work like charm.

Also when talking css under Liferay/Tomcat you might try deleting your server cache, e.g. %catalina_home%/temp ?? (I just delete everything underneath). Tomcat may also cache jsp files which can cause problems files if you're attempting to update them dynamically. I typically delete the catalina work directory in that case. I hope that may help someone.
