During my experience with Liferay Portal I had this problem several times. When uploading a portlet (new or a new version of an existing one) Liferay says the following:
Copying 1 file..
Copying 1 file..
.......
.........war copied successfully.
Deployment will start in a few seconds.
and then nothing happens.
Ok, I have no idea why this happens, I looked into dozen of forums blogs and each of them had different solutions that that did not work. Not only to me but to many other forum members so I got another solution that hopefully will work to you also. Here goes:
All you have to do is delete all the new xml files from the TOMCAT_ROOT/conf/Catalina/localhost folder. By new xml file I mean all of them beside the ROOT.xml (this one being the one that comes with the main Liferay distribution). And then of course, restart Liferay. Also maybe it would be a good idea to make a backup of these files although I never had to use them because new ones are generated automatically.
That is all and if it works to you also.. please provide some feedback.
Until next time,
Long live Rock and Roll !
Finally, there’s another very important peculiarity of what does Cialis that brings it so high above its alternatives. It is the only med that is available in two versions – one intended for use on as-needed basis and one intended for daily use. As you might know, Viagra and Levitra only come in the latter of these two forms and should be consumed shortly before expected sexual activity to ensure best effect. Daily Cialis, in its turn, contains low doses of Tadalafil, which allows to build its concentration up in your system gradually over time and maintain it on acceptable levels, which, consequently, makes it possible for you to enjoy sex at any moment without having to time it.
