  LPS-28555	Plugins cannot be installed via Plugin Installer
  LPS-5177	Plugin Installer not working in 5.3.0
  LPS-29039	Create a hook to display "Private Plugins Installer"
  LPS-29846	Marketplace plugin cannot install plugins if dl.store.impl is S3Store
  LPS-20176	Plugin Installation shows no plugins available

Steps to reproduce:

1. Log in as administrator.
2. Go to Control Panel -> Plugins Installation.
3. Click Install More Portlets.
4. Click Upload File.
5. Browse to a plugin .war file.
6. Click Install.

The installation fails because the Struts action is either missing or not configured. Here's the relevant part of the stack trace:

I am facing the same problem while installing War file through plugin installer in liferay-portal-6.1.10-ee-ga1. Kindly let me know the fix for this issue.

I am also facing the same issue in liferay-portal-6.1.10-ee-ga1. I would also appreciate the solution to this issue. This is an urgent request - an important project depends on it.

Update: I have found that using the "deploy" directory is an acceptable alternate to install on the system. I am still looking forward to a solution to the issue however.

Seems it affects 6.1.1 GA2 too. Someone can confirm?
