I am creating a web content in liferay. I have added a template for my structure.In template,i have chosen velocity as my script language.
I want to access logged in user's name in my vm script.
But when i use $user.getFirstName() as declared in init.vm it doesn't work, not even with $user_first_name as used in portal_normal.vm.
Can anyone help me?

you can use below default velocity variables in web content :
http://www.liferaysolution.com/2011/10/default-velocity-variables-for-web.html .

But to get logged-in user details , you may have to call user service in template and need to set in separate variable using service locator.
And then you can use all the methods to get login user details.

Thanks for prompt reply.
But I don't know how to call user service in template.
I followed this link
http://www.liferay.com/community/wiki/-/wiki/Main/Access+Liferay+Services+in+Velocity#section-Access+Liferay+Services+in+Velocity-The+findService()+Method
but here there is no description for calling user service .

you can use below code in your web content template :

#set($userLocalService = $serviceLocator.findExceptionSafeService("com.liferay.portal.service.UserLocalService"))

Now print $userLocalService and check what and all information you are getting.

It's most probably because you have to allow it via portal-ext.properties.
This can be done by the property

1 journal.template.velocity.restricted.variables=

leaving it blank will allow service locator to get the service

Thanks!! I missed that.But the catch is, its still not working. My variable in template is still not getting set.I have set below mentioned variables.:
#set ($user = $userLocalService.getUser($request.get("theme-display").get("user-id")))
#set($userLocalService = $serviceLocator.findExceptionSafeService("com.liferay.portal.service.UserLocalService

Finally, i got it.

For me the following lines worked :
#set ($userLocalService= $serviceLocator.findService("com.liferay.portal.service.UserLocalService"))

#set ($userId = $getterUtil.getLong($request.remote-user))
#set($user = $userLocalService.getUserById($userId))
#set($userFirstName=$user.getFirstName())

Hope it helps,if someone searches the same.

Thanks for all of this. This really helped me get this sorted out.

For others who might be searching and wanting to access expando content, here's an example of how to do that:

1
2###
3## Don't forget to set journal.template.velocity.restricted.variables=
4## in portal-ext.properties; in other words, set it to nothing to unset the restriction.
5###
6
7## See http://www.liferay.com/community/forums/-/message_boards/message/14789299
8## this is where this comes from
9
10#set ($userLocalService= $serviceLocator.findService("com.liferay.portal.service.UserLocalService"))
11#set ($userId = $getterUtil.getLong($request.remote-user))
12#set($user = $userLocalService.getUserById($userId))
13
14#set ($userFirstName=$user.getFirstName())
15## This is a drop down select, so must be accessed this way
16#set ($class_year = $user.getExpandoBridge().getAttribute("gradYear").get(0))
17#set ($ugrad = $user.getExpandoBridge().getAttribute("UndergradSchool"))
18#set ($userCount=$userLocalService.getUsersCount())
19
20<h2>Getting variables from user, system, and expando</h2>
21<p>Year: $class_year</p>
22<p>School: $ugrad</>
23<p>First Name: $userFirstName</p>
24<p>User count: $userCount </p>
